On the surface, agricultural drones are no different than other types of drones. The application of the UAV simply changes to fit the needs of the farmer. There are, however, several drones specifically made for agricultural use.
On the market can be found numerous types of agricultural drones and here are some examples of very good ones:
- PrecisionHawk's DJI Matrice 200 v2: Many farmers choose exactly the drones of PrecisionHawk and after partnering with DJI in 2016 the company has flourished in the market. PrecisionHawk describes the M200 as the ideal drone for, "the toughest farming environments." It features advanced obstacle detection and can even fly in sub-zero temperatures.
- senseFly eBee SQ: this drone is discribed as the "advanced agricutlture drone." It is popular in the agriculture industry and the biggest selling point is the company's proprietary eMotion software, which makes designing a flight plan incredibly simple. The drone boasts the ability to capture hundreds of acres of footage in a single flight.
- Sentera PHX Complete System: The PHX features a long-range omnidirectional communication link and can collect data from 700 acres. Senetra offers farmers the ability to increase opperational efficincies and perform plant health analytics.
Agricultural Drones Applications
The process of using a drone to map or survey crops is a relatively straightforward one. Many newer agricultural drone models come equipped with flight planning software that allows the user to draw around the area he or she needs to cover. Then, the software makes an automated flight path and, in some cases, even prepares the camera shots.
As the drone flies, it automatically takes pictures using onboard sensors and the built-in camera, and uses GPS to determine when to take each shot. But if your drone does not have these automatic features, then one person needs to fly the drone while the other takes the photos.
In 2015, the Federal Aviation Administration approved the Yamaha RMAX as the first drone weighing more than 55 pounds to carry tanks of fertilizers and pesticides in order to spray crops. Drones such as this are capable of spraying crops with far more precision than a traditional tractor. This helps reduce costs and potential pesticide exposure to workers who would have needed to spray those crops manually.
Future of Agriculture DronesAccording to Global Market Insights the agricultural drone market size will exceed $1 billion and 200,000 units shipped by 2024. GMI attributes the growth through 2024 to increasing awareness of the pros and cons of drones in agriculture among farmers.
The company also claims that technological advancements in farming techniques will push demand during the forecast period. Increased automation stemming from a lack of skilled resources and a labor crisis will also bolster agricultural drone demand. Finally, GMI expects government programs in this sector to permit operations of various sizes to help make farming processes more efficient. | Yes |

AbstractABSTRACT: AutoDrills at Lockheed Martin drill over 12,000 holes in the wing skins and understructure on each F-35 aircraft. To ensure these holes get the correct fasteners, a technician must measure the depth of each hole and mark the dimension on the skin adjacent to the hole. This procedure is known as"gripping". According to Lockheed Martin Manufacturing Technology (ManTech), gripping takes an average of 70 seconds per hole. This amounts to over 230 hours per aircraft. Systems and Materials Research Corporation (SMRC) proposes GripChek, an automated, zero time added, hole depth measurement solution. Technicians tend to use fasteners that are known to be too long. This adds unnecessary weight, and the practice is fundamentally incompatible with the JSF program's ESH mission. Likewise, fasteners that are installed too short must be removed and replaced with the correct fastener. GripChek uses the drilling operation itself to determine and record the depth of the hole in real time - exactly the right length fastener every time. GripChek will benefit the aircraft industry by reducing weight, cost, and waste with zero time added. BENEFIT: SMRC's GripChek solution is simpler, faster, and easier to integrate to an automated drilling system in comparison to any other real-time hole-depth measurement system under development. The baseline technology has been proven by Sandia National Laboratory, and has been addressed as a preferred solution for both Lockheed Martin and Northrop Grumman. SMRC's GripChek system does not rely on added components attached to the drill head, but instead relies on data generated by the AutoDrill controller and minimal sensor hardware attached to the drive harness. GripChek will be cost effective and provide high return on investment. It will eliminate manual hole-depth measurement process saving thousands of labor-hours per aircraft. The maintenance of GripChek will be less frequent and require minimum interruption to the drilling process. SMRC estimates savings of $305Million for the entire Aerospace industry over 27-year time period of GripChek operation.

This report presents the results of flight tests conducted to compare two sidestick controllers with a conventional rotorcraft cyclic, collective, and pedal controller configuration. The sidesticks were tested in several modes ranging from full control of all rotorcraft angular degrees of freedom plus height, to control of just pitch and roll. The emphasis in this document is on issues related to civil certification, including exposure of FAA and Transport Canada pilots to sidesticks. The task emphasized maneuvering in visual meteorological conditions (VMC) very close to the ground, although some traffic patterns and autorotations were flown. Each pilot also flew one or two decelerating instrument approaches with each controller. The test helicopter was the National Research Council of Canada (NRC) variable stability Bell 2O5A, which was augmented with rate feedback to produce angular response characteristics similar to the Sikorsky S-76. Identical rotorcraft dynamics were used for all of the tested controller configurations. This report presents interpretations of the data believed to be directly applicable to U.S. civil certification.

After setting the record for longest American astronaut in space, NASA’s Scott Kelly has landed safely in Kazakhstan. His Soyuz capsule, which he shared with cosmonauts Mikhail Kornienko and Sergey Volkov, touched down at 11.45PM EST yesterday.
The landing, which was described as “textbook” was greeted by search and rescue teams. Kelly was seen triumphally punching the air upon his emergence from the capsule, and soon after took to talking on the phone.
Both Kelly and Kornienko have spent 340 days on the International Space Station (ISS) as part of an experiment on the long-term effects of being in space.
Both will now be subject to extensive testing by NASA and Roscosmos of Russia to see how their bodies have held up after such a long time in microgravity.
During their mission, the men performed various exercises, including using ladders.
Kelly has an identical twin brother, Mark, who has also been an astronaut.
NASA anticipate comparing the two for indicators of health. Findings may help in the pursuit of longer missions beyond our planet, including, perhaps, to Mars.
Last week, in his final news conference from space, Kelly described the area as a “harsh environment”, where you never feel totally normal.
Kelly became famous for having a very “social” year in space. A regular user of Twitter and other social platforms, Kelly posted some spectacular photos of our planet, also making humorous comments on big events such as Super Bowl 50. Just before his departure, yesterday, Kelly tweeted for the last time: “My last sunrise…then I gotta go!”
Kelly, 52, has two daughters and a girlfriend – who also works for NASA. The flight from the ISS was reported to have taken 3 hours in total. After creeping away from the space station at a speed of some four inches a second, once clear the capsule ignited the rocket bursts that set it on a trajectory for home.

A military internet discussion forum has concluded that the new name most favoured for the Lockheed Martin F-35 Joint Strike Fighter when it enters service is Phœnix.
The poll of around 100 readers of F-16.net showed 23% favoured taking the name of the mythical bird that rises from the ashes. Second choice was Lightning II, currently considered most likely US Air Force reporting name to be granted by US president George Bush if he visits Lockheed Martin’s F-35 line in Fort Worth as scheduled next Friday. The aircraft programme's working name, the Joint Strike Fighter (JSF), reflecting the aircraft's use by USA's Marine Corps, navy and air force will be replaced once the aircraft enters service, although the US Department of Defense has refused to reveal any firm plans.
Current DoD nomenclature favours birds of prey, ergo the Boeing F-15 Eagle, the Lockheed Martin’s F-16 [Fighting] Falcon and F/A-22 Raptor. However, it is understood the DoD will break this naming convention and instead honour classic military aircraft.
The UK is a first level partner on the F-35 programme and speculation on the discussion site says the two governments will agree a moniker, leading to rumour of a Spitfire II name.
Lightning II, once reserved provisionally for the F-22, is also on the short list, according to insiders. Other names on a provisional shortlist, leaked to various web forums, are: Cyclone, Reaper, Black Mamba and Piasa. Other names reportedly rejected include Mustang II, Fury, Scorpion, Phantom III and Sky Ruler.

Scientific investigations launching to the International Space Station on the 19th Northrop Grumman commercial resupply services mission for NASA include studies of fire suppression, gene therapy, atmospheric monitoring, and other experiments along with space-flown student artwork. The company’s Cygnus cargo spacecraft is scheduled to launch in August from NASA’s Wallops Flight Facility in Virginia.
Read more about some of the research making the journey to the microgravity laboratory in space:
Testing Gene Therapy for Neurons
Neuronix, sponsored by the ISS National Lab, demonstrates the formation of 3D neuron cell cultures in microgravity and tests a neuron-specific gene therapy. Gene therapy shows promise as a potential treatment for people with paralysis and neurological diseases such as Alzheimer’s and Parkinson’s, but the 3D models needed to test these therapies do not form in Earth’s gravity. Creating 3D cell cultures in microgravity could provide a platform for drug discovery and gene therapy testing.
Final Fire Experiment Upon Departure
Understanding how fire behaves in space is vital for developing fire prevention and fire suppression methods, but flame-related experiments are difficult to conduct aboard an occupied spacecraft. The Spacecraft Fire Experiments (Saffire) use the Cygnus resupply craft after it leaves the space station to remove the risk to crew and spacecraft. Saffire-VI is the last of this series, building on previous results to test flammability at different oxygen levels and to demonstrate fire detection and monitoring as well as post-fire cleanup capabilities.
“The Saffire experiments provide a critical benchmark for validating our models of how fire affects spacecraft habitability,” says David Urban, principal investigator. “This work has already changed our understanding of material flammability in low gravity and demonstrated that just as on Earth, smoke from a fire represents the most immediate hazard to the crew.”
Measuring Atmospheric Density
The Multi Needle Langmuir Probe (m-NLP), an investigation from ESA (European Space Agency), monitors plasma densities in the ionosphere – where Earth’s atmosphere meets space. The space station is an ideal platform for the instrument since it orbits near the peak plasma density of the ionosphere.
“The probe can take ionospheric density measurements at unprecedented spatial resolution,” says co-investigator Lasse Clausen at the University of Oslo. “This means that we can investigate plasma structures down to sizes of a few meters and study their generation, evolution, and decay.”
Small plasma structures in the ionosphere regularly affect the accuracy of satellite navigation systems like GPS, he adds. “These measurements could help us understand the root cause of those inaccuracies and, in the future, to build models that predict problems with the quality of signals.”
Better Water for Explorers
A water system launched in fall 2008 provides water for crew consumption and food preparation on the space station. A new system, Exploration PWD, uses advanced water sanitization and microbial growth reduction methods and dispenses hot water.
The team can take Exploration PWD in and out of dormancy, an ability that is key to its use on future exploration missions. Katherine Toon, an ECLSS integration manager, points out that the Exploration PWD system also has data collection, telemetry, and self-monitoring abilities, features that provide engineers direct insight into how the unit is behaving. It also can be commanded from the ground. After successful demonstration, this technology could be used on future exploration missions and on the space station.
For I-Space Essay, JAXA (Japan Aerospace Exploration Agency) is sending a memory card that contains digital works created by students, such as pictures and poetry, to the space station. More than 13,000 students from 74 schools created digital works for the project. JAXA plans to issue a certificate to participating schools after the flight and participation could inspire the next generation of scientists, engineers, and explorers.

On 10 August, a Norwegian Boeing 787-8 (LN-LND) operated flight DY7115 between Rome Fiumicino, Italy and Los Angeles, United States. During take-off from runway 16R, however, the aircraft suffered a left engine (Rolls Royce Trent 1000) failure. The Dreamliner immediately returned to Fiumicino and safely landed 25 minutes after its initial departure.
The aircraft carried 298 passengers. Fragments of the engine hit some 12 houses and 25 cars in Isola Sacra, near Fiumicino. One bystander was hit by falling debris, but he was just frightened and remained uninjured.

When it comes to the high-reliability aerospace and defense industry, the printed circuit boards (PCBs) used in electronic systems must meet strict requirements for performance, durability, and reliability. NetVia Group is a leading provider of PCB solutions for the industry, offering a range of services that are specifically tailored to the unique needs of aerospace and defense applications.
High-reliability printed circuit boards have come to define NetVia Group. Our customer list includes some of the biggest companies in the military and aerospace industry and they keep coming back to NetVia due to our service, quality, and our experience in understanding the complexity of PCBs that go into these applications.
Below are some reasons why NetVia Group is the best solution for printed circuit boards for the high-reliability aerospace and defense industry.
NetVia Group has extensive experience in working with a wide range of materials that are commonly used in the aerospace and defense industries. This includes high-temperature laminates, polyimide, Rogers, Tachyon, and other advanced materials that are capable of withstanding extreme conditions, such as high altitude, temperature, and pressure.
Our team of experts has a deep understanding of the properties and characteristics of these materials, which allows them to select the best material for a particular application and ensure that the PCB meets all necessary requirements for performance and reliability. As well as having experience, we have a significant amount of material in stock in order to allow us to move quickly to produce circuit boards for our customers.
NetVia Group has a high PCB layer count capability, meaning that it can manufacture circuit boards with a large number of layers. This is particularly important for aerospace and defense applications, as these systems often require complex PCBs with many layers to accommodate the necessary components and functionality. Our high layer count capability and 20+ years of experience, allow us to manufacture PCBs that meet these requirements while still maintaining a high level of quality and reliability.
NetVia Group has made significant investments in state-of-the-art equipment and technology to ensure that they can provide the best possible PCB solutions for aerospace and defense applications. This includes advanced manufacturing equipment, such as laser drilling machines, laser direct imaging equipment, the latest plating, and via-fill technology, which allow us to create precise, high-quality PCBs with complex features such as blind/buried vias. Our commitment to investing in the latest technology ensures that we will continue to be able to produce the highest level of quality and reliability in our printed circuit boards.
One of the most important aspects of ensuring the reliability of PCBs for aerospace and defense applications is rigorous testing. NetVia Group has a comprehensive in-house microsection lab and testing program that includes both automated and manual testing methods to ensure that every PCB they manufacture meets the necessary standards for performance and reliability.
This includes in-house testing as well as third-party testing (when required) to ensure that the PCBs can withstand the most extreme conditions and environments.
Blind/buried vias are a critical component of many aerospace and defense PCBs. These vias are used to connect different layers of the circuit board without passing all the way through the board, which allows for a more compact and efficient design. We have extensive experience in manufacturing PCBs with blind/buried vias, and our advanced equipment and technology allow them to create these features with a high level of precision and accuracy.
Heavy copper is another critical component of many aerospace and defense circuit boards. These PCBs require thicker copper layers to support higher currents, which can be challenging to manufacture. NetVia Group has the experience and equipment necessary to manufacture PCBs with heavy copper layers up to 5 oz, ensuring that the PCBs can handle the necessary current loads while still maintaining a high level of reliability and performance.
Laser drilling is a key technology for manufacturing complex PCBs for aerospace and defense applications. This technology allows for precise, high-quality drilling of small holes and vias, which is critical for creating PCBs with a high layer count, blind/buried vias, and other complex features. We have made significant investments in laser drilling technology, ensuring that we are able to manufacture parts that require micro vias for our high-reliability military and aerospace customers.
NetVia Group's capabilities extend beyond traditional rigid PCBs, as we are also able to produce flexible and rigid-flex circuit boards for high-reliability mil-aero applications. These types of PCBs are particularly well-suited for applications where space is limited, and where the PCB must be able to bend or flex without compromising performance or reliability.
Our experience with advanced materials and manufacturing techniques, as well as our commitment to rigorous testing, quality control, and investment in the newest equipment sets, make us an ideal partner for producing flex and rigid-flex PCBs for the most demanding mil aero applications.
As we have been servicing Tier One defense and aerospace customers for many years, we are very familiar with all the different specifications that apply to printed circuit boards. We can build and test products that comply but are not certified to, MIL-55110, MIL-31032, and AS-9100. See our blog post on IPC Class III vs. MIL Spec for Printed Circuit Boards to get more information about how we can produce parts in compliance with the standards.
In addition to IPC-6012/6018 Space Addendum and/or class 3, NetVia Group also caters to individualized requirements set forth by our clientele, which can include 3rd party lab verification, data/coupon retention, lot traceability, source inspection, key characteristic measurements taken while in process and many others flowed down quality requirements. We are also JCP, DD2345 certified. | Yes |

"Earth’s distant orb appeared the smallest light that twinkles in the heaven; whilst round the chariot’s way innumerable systems rolled and countless spheres diffused an ever-varying glory. It was a sight of wonder: some were hornèd like the crescent moon; some shed a mild and silver beam like Hesperus o'er the western sea; some dashed athwart with trains of flame, like worlds to death and ruin driven; some shone like suns, and as the chariot passed, eclipsed all other light."

The Last Man On The Moon
“The Last Man On The Moon” is just excellent, a thoroughly enjoyable read and if you haven’t read any astronaut autobiographies before I’d recommend this one as a good place to start, despite it being the last in the series, so to speak. Although for a really detailed look at Gemini and Apollo you can do no better than Michael Collins autobiography “Carrying The Fire”.
Cernan’s book follows the story of the space race as seen through the eyes of a Navy aviator watching the unfolding events of Sputnik, Gargarin and Mercury right through to his own considerable involvement in Gemini and Apollo. It captures the competitiveness of astronaut life including the revelation that Cernan had a serious leg injury that he and one of the NASA doctors played down to avoid him losing the historic Apollo 17 flight. Cernan speaks about the result on family life of large egos, a massive work load, extreme pressure and the worry over whether a spouse would actually come home at the end of the day, not just from space flight but from all the other flying undertaken during an astronaut’s working day on earth. Astronaut wives were taken for granted by NASA and let’s be honest by the astronauts themselves. It was expected that they put on a show for the press for ever telling them they were “proud, thrilled, and happy” while they almost certainly felt stressed out, under pressure and scared and Cernan acknowledges this in his book. Although he survived his time as an astronaut, his marriage did not and he takes the blame for it.
Gene Cernan may well be the last man on the moon for many years to come. I suspect the next person on the moon will either be Chinese, and good luck to them I hope they make it, an extremely wealthy individual with as much courage and skill as money, or maybe a very fortunate person with those abilities who has the financial backing of an extremely wealthy individual or corporation. Whoever it is though could do worse than to read a few astronaut autobiographies before they go because nothing about being in space is easy or safe, something highlighted in Cernan’s book.
Working within the confines of a space suit makes the simplest task a huge undertaking and while space suits have improved and developed since Apollo that is a fact that cannot be altered. Working or even just manoeuvring in the totally weightless environment of space brings about problems of leverage and action/reaction. Even on the lunar surface with its low gravity, forcing a drill bit into the solid moon rock found under all the surface dust is still very strenuous work.
On the moon, even something as simple as holding on to a rock or a tool involves using a very tight grip through the many layers of a protective glove. Both Cernan and his fellow Apollo 17 moon walker Harrison Schmitt had blisters and cuts all over their hands as well as aching arms and legs that would stop most of us in our tracks. They had to work through the pain for three days on the lunar surface. When things broke or didn’t work properly it was tough, exhausting and time consuming to persevere or make repairs, if repairs could be made at all.
Living and working on the moon is never going to be easy and it’s tragic that we aren’t able to take advantage of the experience of those who have already worked in those conditions while they’re still with us. The giant leap and those few first steps should have lead us on to a running pace by now but the next time the moon has visitors from earth, they too will have to make small steps.
I don’t expect that Gene Cernan will remain the last man on the moon. Almost certainly one day, and it may be 50 years from now or 500, but one day people will again walk on the lunar surface. However, Cernan will always be the last Apollo astronaut and the last man in the twentieth century to kick up the dust of that magnificent desolation that is the surface of the moon and you can share in that experience by reading his book.
As for me, my next astronaut book is Deke Slayton’s autobiography. He was one of the Original 7 Mercury astronauts but who was grounded by health concerns. Although he missed the opportunity to fly as part of the Mercury, Gemini or Apollo moon missions he was in charge of all the other astronauts at NASA and he finally got to earn his astronaut wings as the docking module pilot of the Apollo-Soyuz Test Project. We have lift off, again.

China has flown its first indigenous long-range offensive drone (UAV) amid tensions in India and the United States. According to Chinese media, this unmanned aerial vehicle named WJ-700 successfully completed its first flight on Tuesday. This Chinese drone looks like the United States’ MQ-9 Reaper in real time. Which is made by General Atomics, America’s leading arms maker. It is even claimed that this Chinese drone can perform long-range reconnaissance missions and attack enemy hiding places.
How powerful is the Chinese drone WJ-700
This Chinese drone has a variety of special sensors and cameras, which allow it to perform reconnaissance and surveillance over long distances. Even in Chinese media, it is claimed that it can be used easily even in high altitude areas like Tibet. In addition, this UAV will be equipped with air-to-surface missiles. So that it can easily blow any ground to the ground. It will deploy the C-701 missile, the CM-102 anti-radar missile and the C-705 KD missile.
This drone can fly for 20 hours
The famous defense publication Janes reported that the Chinese drone WJ-700 is equipped with turbojet engines. With which this drone can effectively fly at higher altitudes in the air. The maximum take-off weight (MTOW) of the WJ-700 is 3,500 kg. In other words, this drone can carry missiles in addition to its load. This drone can fly in the air for up to 20 hours at a time.
Suspicion arising from China’s claim
Images published in Chinese media show this drone on the runway. On the other hand, on the trail, those associated with this mission are seen celebrating with a banner. However, no such image has been released in which this UAV is seen flying through the air. In such a situation, experts have cast doubts on this claim by China, because the world knows the difference between its words and its actions. The media is also working under the Chinese government, so his report can not be trusted either.
Deployment of WJ-700 drone will take longer
The WJ-700 drone was ordered by the third research institute of the China Aerospace Science and Industry Corp (CASIC), Heaving Aviation General Equipment Company Limited. After the first flight, this drone will now be assigned to the Chinese Air Force PLAAF, which will conduct flight tests of this drone over the coming months. At present, this UAV will certainly take at least a year to join the Chinese military.
China has already been accused of stealing the technology
China has been accused of stealing many weapon technologies from the United States and Russia in the past. A few days ago, the Chinese Air Force released a video showing their H-20 stealth bomber. This bomber also appears to be a copy of the American B-2 Spirit. Apart from that, the so-called J-20 stealth fighter plane that China has built is also based on technology from the US F-35. Other than that, China made the J-10 on the lines of the US F-16 fighter jets. The Chinese J-11 looks like Russia’s Sukhoi SU-27. | Yes |
Russian Helicopters Delivers Five Mi-171Sh Helicopters to Bangladesh
OREANDA-NEWS. Russian Helicopters (part of State Corporation Rostec) delivered a batch of five military transport Mi-171Sh helicopters to Bangladesh's Ministry of Defence. In addition to regular cargo transportation operations and border security provision, the new Mi-171Sh will be used in UN humanitarian missions and in regions facing complex crime problems.
Bangladesh received the Mi-171Sh helicopters under state credit for the purchase of Russian military goods. The contract was concluded by Rosoboronexport in late 2013. The Mi-171Sh helicopters delivered are equipped with the latest avionics, enabling them to land safely at any time of day or night in any weather conditions.
'The geographies to which we deliver modified Mi-171 helicopters expand every year. Today they are in use in Brazil, China, Ghana, Indonesia, Kazakhstan, Peru and beyond. There are real opportunities to continue to deliver the Mi-171Sh to Bangladesh,' said Russian Helicopters CEO Alexander Mikheev. 'We produce high-tech multirole helicopters, which are designed to complete highly complex missions anywhere in the world.'
'Our choice of partners is absolutely clear and fully grounded, the Mi-171Sh is ideally suited to operation in Bangladesh's environment and climate. In addition, our helicopters are renowned for their resilience and ease of operation,' said Leonid Belykh, Managing Director at Ulan-Ude Aviation Plant. 'We are constantly modernising Mi-171Sh helicopters, expanding their operational capacity.'
The helicopters are equipped with additional fuel tanks to increase range and length of flight, as well as an external sling for large cargo transportation. They boast enhanced efficiency thanks to the powerful spotlights and winches that can lift 150 kg, can be fitted with medevac equipment to evacuate up to 12 injured people. They are equipped with armour and protection systems for operation in areas that see heightened activity by terrorist or organised crime groups.
The Мi-171Sh – military transport helicopter is developed on the basis of the Mi-171Sh (Mi-8AMT) and is designed to combat armored ground, surface, immobile and mobile small targets, to destroy enemy forces, transport military cargo, troop delivery, day and night, in regular or complex weather conditions, in a variety of climates. The helicopter can be equipped with the latest small arms, rocket, bomb and gun weapons systems, and protection against attack. The helicopter is designed to transport up to 37 paratroopers, and to transport cargo of up to 4,000 kg, up to 12 injured on streatchers, and to carry out search and rescue operations (including CSAR).
Ulan Ude Aviation Plant – is a production enterprise at Russian Helicopters. Its modern production and technological capacities enable it to quickly launch work on new rotorcrafts, create prototyopes and launch series production. In the 75 years of its existance, it has produced over 8,000 aircraft. Today it specialises in producing Mi-8AMT (Mi-171), and the Mi-8AMTSh (Mi-171Sh) helicopters.

The new head of Russia's national space agency confirms that Russia will leave the International Space Station in 2024, when its current commitments end.
Russia will opt out of the International Space Station (ISS) program after 2024, the new chief of Russia's federal space agency Roscosmos has said. The decision comes at a time when the West has isolated Russia in terms of trade and finance over the Kremlin's war on Ukraine.
The Roscosmos leadership had been threatening to pull out of the International Space Station for months raising concerns of the Western sanctions destroying the Russian cooperation aboard the orbital lab. The latest proclamation made by the new Roscosmos chief Yuri Borisov underscores the space cooperation falling apart.
"The decision to leave the station after 2024 has been made," said the current head of Roscosmos, Yuri Borisov, according to space.com.
As per reports, Russia is looking into potential projects that can replace the ISS after 2024 and is currently working on extending the operation of the ISS past 2024. Earlier, the expiration date of the ISS was set for 2024, but it has now been shifted further.
"Of course, we will fulfil all our obligations to our partners, but the decision to leave this station after 2024 has been made," said Borisov in the report.
Borisov replaced Dmitry Rogozin as the head of Roscosmos after the latter was personally removed by Vladimir Putin. Borisov is a former Deputy Prime Minister with a military background, who is known for his bombastic statements and eccentric nationalist behaviour.
Borisov called the decision to go solo and build Russia’s own space station as "raising the bar" in the space industry. He also mentioned that it is Russian space programme’s “main priority".
Until now space exploration was one of the few areas where cooperation between Russia, the United States and its allies were not affected by the ongoing tensions over Ukraine and elsewhere. However, with this proclamation, the cooperation seems to be nearing its end.
The International Space Station is the largest modular space station currently placed in the lower Earth orbit. The ISS is a collaborative project involving five participating space agencies - NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). | Yes |
Four Eurofighter Typhoon jets have arrived in Seoul Tuesday morning to take part in the first-ever trilateral combined air exercise with South Korea and the US.
This aerial drill marks South Korea's first domestic air combat maneuver with a foreign country other than its main ally, the United States.
Typhoons arrived at Osan Air Base in Pyeongtaek, Tuesday morning along with a Voyager tanker aircraft, a C-17 Globemaster III transport aircraft to be part of the weeklong "Invincible Shield" drill that ends Thursday, Yonhap reports citing a joint Air Force statement.
"This exercise is helping to deepen further the relationship between the Republic of Korea Air Force and the Royal Air Force (RAF), and I have taken enormous pride from witnessing our Air Forces join together to enhance even further cooperation between our countries," RAF's Chief of the Air Staff Stephen Hillier said in the statement.
U.S. 7th Air Force Commander Lt. Gen. Thomas Bergeson said the combined drill with South Korean and British air forces will help protect peace and security on the Korean Peninsula from the North's provocations.
"This exercise offers the opportunity to develop interoperability between different types of aircraft and weapons systems, and try out various tactics and techniques, thereby greatly contributing to improving the operational capabilities of each air force," a statement by the U.S. officer said.

Need an research paper on the history of the soviet and russian space exploration. Needs to be 10 pages. Please no plagiarism. Man has had an interest in space since time immemorial but the dream of space travel could only be satisfied when advances in rocket technology could make this dream possible (RussianSpaceWeb. com, “Pre-20th Century Developments”). Russia had established a rocket production plant as early as 1861 and Nikolai Ivanovich Kibalchich (1854 – 1881), a revolutionary who was to hang for his involvement in the assassination of Emperor Alexander II, had proposed the idea of slowly burning explosives as being useful for aeronautical applications. Thus, interest in space exploration had been present in Russia before the twentieth century but the practical realization of dreams could only be fulfilled because of advances in physics, chemistry, and aeronautics, which were supported by economic development. Russia’s space exploration program was to receive a boost from efforts made in Germany to design long-range rockets during the Second World War (Harvey, “Russian Planetary Space Exploration” pp. 17 – 35). On May 4, 1945, Russian troops had occupied the German rocket research center at Peenemünde and this led to efforts directed towards improving on German rocket technology and incorporating the results in Russian technology (Chertok, pp. 1 – 15). Later, in 1950, a team led by Sergei Korolev was to study a multi-stage version of the R-3 rocket that was capable of launching a satellite into space and this was a departure from German efforts. However, Russian efforts to develop technology for long-range space exploration were not easy and it was difficult to tame the Molniya and Proton upper stages (Harvey, “Russian Planetary Space Exploration” pp. 17 – 35). A long journey was to be undertaken before the development of the Mir space station was possible and efforts continue to keep the dream alive and to expand the frontiers.

DePete on DAC: Representing ALPA, Advising the Industry
By Christopher Freeze, Senior Aviation Technical Writer
Michael Chasen, chair of the Drone Advisory Committee and CEO of PrecisionHawk, Inc., left, and Capt. Joe DePete, ALPA president, attend the Drone Advisory Committee meeting held in June in Arlington, Va.
On June 6, the FAA’s Drone Advisory Committee (DAC) convened its first meeting of 2019 in Arlington, Va., to provide guidance from governmental and industry stakeholders to the agency on integrating drones or unmanned aircraft systems (UAS) into the national airspace system.
“We’re no longer talking about what’s going to happen with drones in the future. It’s happening now,” said Michael Chasen, the CEO of commercial drone and data company PrecisionHawk and chair of the DAC. “And this group needs to work closely with the FAA to ensure that we have the proper framework to handle the exponential growth in deploying drone technology that we expect to see over the next few years and months.”
Capt. Joe DePete, ALPA’s president and newly appointed DAC member, represented airline pilots and labor interests, urging the committee to remain focused on safety. He cited the need for drone detection systems to be installed near airports as part of a layered approach to mitigating the risk from drones.
“We don’t have to wait until all the pieces are in place for counter-drone systems near airports. Let’s start with detection and build a more complete drone security solution as the technology and legal process allows,” he said.
DePete, who previously served on the subcommittee responsible for carrying out the DAC’s work, reminded members that “safety is everyone’s responsibility.” He also expressed support for the FAA’s outreach efforts, which will include a drone safety and education week taking place in mid-November.
The FAA Reauthorization Act of 2018 contained 50 provisions directly related to UAS, from establishing FAA authority over all UAS operating in the national airspace system and prioritizing integration to closing the “hobbyist” loophole.
The FAA has held several briefings with the DAC, discussing the outlook on rules that will establish requirements for remote identification and tracking small UAS, outreach efforts such as the upcoming “Drone Safety Week,” and developing a knowledge test for recreational flyers.
During the June meeting, the DAC accepted four assignments from the FAA.
1. Develop recommendations for early equipage of remote ID for drones. At present, a final rule from the FAA is likely up to 24 months away, and there will be a period of time before compliance is mandatory. Of particular interest to the FAA are technologies that could be voluntarily used by manufacturers or operators in the interim and how their use might differ from and impact what may be in the final rule. The committee was also tasked to determine what incentives or other drivers could be used to encourage early adoption of remote ID technologies.
2. Identify current existing or emerging technical solutions at the aircraft or operational limitation/capability level that would reduce threats to safety and security. The DAC was charged with determining actions—to be taken by the FAA and agreed to by industry—that would substantially reduce the likelihood of unintentional threatening behavior by UAS operators and improve security.
3. Review and recommend improvements to the FAR Part 107 waiver process. Currently, waivers to the rules are the primary mechanism for conducting expanded operations such as night operations and flights operating over populated areas.
4. Review the FAA’s UAS integration plan. DAC members were tasked with assessing the FAA’s comprehensive plan for UAS integration as required by the FAA Reauthorization Act of 2018.
The DAC was created in May 2016 to advise the FAA on priorities, formalize stakeholder input, and make recommendations to the agency for a safe, comprehensive UAS integration strategy. Its 34 members represent a wide variety of UAS interests, including industry, government, academia, retail, and technology. Members include leaders and CEOs of organizations and companies such as ALPA, Alphabet, Amazon, Boeing, DJI, Intel, the National Air Traffic Controllers Association, and UPS. ALPA’s Air Safety Organization has continually called for the safe integration of drones into national airspace and robust training requirements for their pilots. | Yes |
A Delta Air Lines Inc. (NYSE: DAL) flight and a Singapore Airlines 777 came close to colliding mid-air near Houston's Bush Intercontinental Airport before air traffic controllers corrected their courses, reports Houston Chronicle.
The incident occurred Thursday just before 7 p.m. when the Singapore jumbo jet flew within 200 feet vertically and within a little more than a half-mile horizontally of a Delta Airlines A320 – a separation of about eight football fields horizontally, the paper reports.
Federal Aviation Administration rules require aircraft to remain separated a half-mile vertically and 3 miles horizontally, the Houston paper adds.
The FAA is investigating.

Two methods are applied to the problem of trajectory optimization for launch vehicles which burn solid propellant. One is 'Optimal Control' theory, the other is 'NonLinear Programming' method. Trajectory optimization for solid rocket motors has a special problem. The special problem is that the payload of launch vehicle is not the function of control variable. This paper deals with this special problem.

We did it. And it was not easy we make the SuSi just better!
Stephan Stiegler tells: “I remember the first generation of the SuSi which had no certification (only load-tested). I built it only for myself because I wanted a wing for hike&fly which should be light, simple but performing. Today it still offers its typical flying sensations, it’s more robust than ever, and pilots all around the world can rely on the SuSi like they do since so many years!” | Yes |
|B&H Airlines and Croatia Airlines score high in AirlineRatings safety review|
B&H Airlines and Croatia Airlines have been named the safest airlines in the former Yugoslavia, in an annual global review conducted by “AirlineRatings”. For a third consecutive year, the two carriers scored highest for safety, receiving six out of seven stars, ahead of Adria Airways and Air Serbia, which settled for five stars. Montenegro Airlines received a ranking of four stars. B&H, Croatia Airlines and Montenegro Airlines all scored lower than last year, when the Bosnian and Croatian carriers boasted a perfect seven star score, while Montenegro Airlines received five stars In 2014. On the other hand, Adria and Air Serbia maintained last year’s results.
B&H Airlines and Croatia Airlines fared well as they both have successfully undergone an IATA Operational Safety Audit, are allowed to operate within the European Union, have had no fatalities in the past ten years and are endorsed by the United States Federal Aviation Administration (FAA). However, the two airlines failed to receive a perfect score as their countries did not achieve top marks in all eight of the International Civil Aviation Organisation’s (ICAO) safety perimeters. The eight ICAO audit parameters that pertain to safety are legislation, organisation, licensing, operations, airworthiness, accident investigation, air navigation service and airports. Bosnia and Herzegovina scored lower in accident investigation and organisation, while Croatia received lower scores in legislation and airports. These concerns do not necessarily indicate a particular safety deficiency in the air navigation service providers, airlines, aircraft or airports, but, rather, indicates that “the state is not providing sufficient safety oversight to ensure the effective implementation of applicable ICAO standards”, the regulatory body says. It should be noted that “AirlineRatings’” scorecard for EX-YU airlines is based on ICAO's last audits conducted between 2009 and 2011.
Australia’s Qantas Airways has been declared the world’s safest airline for a third year in a row, followed by Air New Zealand, British Airways, Cathay Pacific, Emirates, Etihad, EVA Air, Finnair, Lufthansa and Singapore Airlines. "AirlineRatings" is the first website to independently rate airlines on safety. The company’s rating system is endorsed by ICAO and rates 449 carriers. “AirlineRatings” has been used by millions of passengers from 232 countries. The editorial team has won almost fourty international and national awards and have also authored or co-authored more than 27 industry books.

Sustainable Aviation Fuel: The journey to creating greener air travel
Our final episode of our podcast mini-series, The Driving Force, welcomes Jacqueline (Jacqui) Sutton MBE, Former Chief Customer Officer at Rolls-Royce Civil Aerospace, to be our guest. Jacqui talks about her experience in the aviation industry, the impact of Covid 19, how far the industry has progressed with the development of sustainable aviation fuel and other key innovations that are aiming to ensure that we can keep taking to the skies without destroying the environment.
Read on for some snippets of this fascinating conversation, or listen now to the full episode.
What innovations did you see as a result of the pandemic?
‘One of the amazing innovations that happened was the adaptation of the engine sensor information that we already use, but cobbling that together with other databases that we’d got, in order to gain really important information about which aircraft was flying, for which airlines and in which parts of the world. Because another thing you’re under pressure to produce, of course, for your investors and for, for the banks that are considering whether to lend you more money, was some kind of forecast of when things were going to come back. Or how would we know which types of aircraft and how many would be flying again, you know, in three months time, six months time. So the data of what was actually happening out there was really important.’
How important do you think air travel is to us as human beings?
‘I think that travel connecting people is a force for good. I genuinely believe that. I think if you think about stereotypes, prejudice, misunderstandings, you know, they tend to arise from lack of awareness, experience, particularly of people. Air travel has provided the opportunity to connect people that would never otherwise have been connected. But that doesn’t mean that the aviation industry itself shouldn’t take responsibility and do something about the impact that it has on the climate.’
Is it possible to power aircraft by electricity or hydrogen?
‘There’s what you call the commuter planes. A commuter plane would be fewer than 50 seats doing, you know, on average, less than an hour’s flight. These kinds of aircraft, research shows could actually be modified to either be electric or hydrogen powered.
‘[For longer flights], they’ve got a larger aircraft to do it with, and therefore they’re burning more fuel to do so because they’re heavier. If you do the trade, you know of either hydrogen or battery, it simply wouldn’t be worth carrying that extra weight around. So the battery I’m sure you would all understand is heavier. But my understanding on the hydrogen side, there would be liquid hydrogen for which you need heavy, very well reinforced fuel tanks that are literally four times the weight of of a normal kerosene fuel tank on an aircraft. So you can quickly see that the trades not going to work. So you’re now in this sustainable aviation fuel category.’
What is Sustainable Aviation Fuel (SAF)?
‘It’s sometimes also called biofuel. And it’s a fuel that’s very cleverly made out of waste, oil, or fats or domestic waste. The reason it’s sustainable is that it’s coming from sources that are non food stock or water supply related. And you know, in a way you’re kind of recycling the carbon that would have been made to produce that oil in the first place. That’s now a waste oil. So it’s quite a smart solution. And the attraction of it is that it has 80% greater efficiency from a carbon footprint perspective than kerosene does.’
Have any flights actually used SAF or is this still being developed?
‘It’s already happening. There’s something around 440,000 flights have already happened using sustainable aviation fuel.’
What are the challenges in moving towards using SAF?
‘The ability to get enough of it, partly the cost, but also, because it’s still being proven.
‘There are aspects around the fuel tanks on the aircraft, and the Airbus’ and Boeings have to continue to do some work around 100% SAF and its ability to circulate around the aircraft and the fuel tanks. So to get to 100%, there’s still some work to be done not just by the engine manufacturers, but also by the aircraft manufacturer. But the supply problem yes is the biggest’
Does the move towards SAF need to happen quicker and who’s driving that?
‘I think, undoubtedly, there’s a feeling that it needs to happen more quickly, because the scale of the challenge is so great. And the airlines for one, feel, we’ve pinned our colours to the mast by making this netzero 2050 commitment. But we need the supply in order to have a hope of being able to get there and some governments are being more proactive than others .’
What do you think governments should be doing to support the move towards SAF?
‘The IATA Director General makes a very good point about that incentivized carrot approach being much more effective than the stick approach. So government has historically taxed airlines in terms of carbon with air passenger duty, it’s called. So those of us that fly will have paid that extra tax on the ticket. But the point they make is that that tax doesn’t then get recirculated and used for green purposes. So it’s just an extra tax. If you build something that properly incentivizes, and we pay more on our ticket, but it’s incentivizing around SAF production, you’d feel better wouldn’t you because you’d be able to see how that is being used, as an investment to accelerate and grow the supply.’
What other innovations have you seen in the airline industry that are improving its sustainability?
‘There’s a business that’s introduced something called Wheel Tug, where they basically installed a very simple, twin electrical motor device into the rim of the nosewheel of the aircraft, which means that it’s powered by the APU, which is the auxiliary power unit at the back of the aircraft. But this electrical wheel tug can basically then be used to steer the aircraft out onto the runway or back onto the ramp. And the advantage of that is that in certain cases, airlines have to use engine power to guide themselves back to the stand, which is obviously much less efficient than just a couple of electrical motors on the nosewheel being able to guide the aircraft around.’

The IDF assesses that its bases and runways could potentially be targeted by enemy missiles during wartime, leading to a decision to consider the purchase of a JSF (Joint Strike Fighter) squadron with vertical take-off and landing capabilities (VTOL), such as the F-35B.
According to Lockheed Martin, the F-35B employs a short-takeoff/vertical-landing (STOVL) capability via a shaft-driven lift fan propulsion system. The STVOL, designed to replace the AV-8B Harrier, also carries a refueling probe fitted into the right side of the forward fuselage. It has more than twice the range on internal fuel, operates at supersonic conditions, and houses internal weapons.
"The plan is that we will get the F-35 as soon as it's possible," a senior IAF official told Aviation Week & Space Technology. He noted that the IAF will eventually acquire more than 100 F-35s and emphasized that the IAF wanted the JSF "the minute it is available."
A senior Israeli general explained that "the number of aircraft [we obtain initially] could be irrelevant...The main issue now is that we get the first squadron as soon as possible. We give the basic capability to the squadron, and later on we increase it [with technology upgrades]...At the beginning, we expect to get at least one squadron, with more to follow by the end of the decade [in 2020]."
The Israeli rush to gain VTOL capability is certainly understandable, as the Jewish state faces the possibility of sustained missile and rocket attacks from at least three enemy states: Syria, Iran and Lebanon (via Hizballah).
The Israel Missile Defense Association (IMDA) notes that during the Second Lebanon War, (July 12 - August 13 2007), the IDF Home Front Command reported 3,970 rocket impacts in Israel. 907 rockets impacted on buildings or in close enough proximity to cause severe damage. 1,012 rockets landed in the northern city of Kiryat Shemona, while the coastal Nahariya sustained 808 rocket impacts. In addition, the Port of Haifa was forced to close and the Navy base at Haifa relocated south.
Hizballah still maintains an impressive arsenal of lethal projectiles that includes: Katyushas, 220mm and 302mm rockets, the FADJR-3 and FADJR-5, the Zelzal-2, the C-802 and Fatah-110.
Wyn Q. Bowen and Joanna Kidd estimate that Syria has a stockpile of several hundred SCUD-B, SCUD-C and SS-21 missiles. Damascus may also possess a number of SCUD-D missiles with a range of 650 kilometers. In addition, the Assad regime maintains 10 squadrons of fighter-ground attack aircraft (including Su-24, Su-22 and MiG-23 BN) and 16 squadrons of fighter aircraft (including MiG-21, MiG-23, MiG-25 and MiG-29A and Su-27).
According to Steven A. Hildreth, a specialist in missile defense and non-proliferation, the Iranian Shahab-3 (a derivative of the North Korean No-Dong 1 ballistic missile) is reportedly capable of achieving a range of 1,000-1,500 kilometers. The Shahab-3A may have a range of 1,500 to 2,500 kilometers and could potentially reach targets throughout the Middle East, Turkey and southern Europe. | Yes |
Yes, the rotation of satellites makes some interesting patterns like this in image sets.

Wait til we catch an iridium flare - when an iridium satellite (a communications satellite, not related to the metal) is canted just right, you get a HUGE flash. There are several places on the web where you can see when one will be visible where you are. They're quite startling.
With the short type flair ranging up to −8 magnitude. And the longer, but less bright, flair going up to −3.5 magnitude. It makes more sense to presume CSS would actively avoid them.
YouTube video: Iridium flares in real-time (Nov 2014)
Digging around a bit more:
- Iridium satellites are in low Earth orbit. (lower is faster orbital time)
- The lower a satellites the less observable sky area(declination limit) there is to catch it.
How fast: (track length)
Geostationary satellite: 360/246060/2 = 7.5 acrmin/(30sec), ~70% of cell frame.
Active Iridium satellite: 360/100.45957/2 = 1.792 deg/(30sec), ~63% of Master frame, ~10.5 cell frames.
ISS: [410..330] km, or ~[93..91] min/orbit, ~[68%..69%] Master frame, 11 Cell frames.
As ISS is in a even lower Earth orbit than Iridium satellites, its probably a very rare to a none-item on the CSS images too.
Active Iridium satellite: 781 km = 100.45957 min/orbit.
Spare Iridium satellite: 666 km = 98.04936 min/orbit.
Master frame size(H/V): 2.86 deg = 171.60 arcmin.
Cell frame size(H/V): 10.7 arcmin = 0.2 deg. (no cell overlap included!)

Currently, there are a couple of options to gather stick force data from flight test aircraft. Either the aircraft is instrumented with costly piezoelectric force sensors and recorders integrated into the aircraft stick, or the test pilot must use a traditional analog stick force gauge with a pointer and telltale. The conventional stick force gauge works well when the pilot has the mental and physical bandwidth to read and remember, or record, the stick force values throughout the maneuver but does not suffice when in a task saturated, high g force maneuver such as the windup turn. This project proposes and evaluates a cost-effective automated recording system to collect stick force data using a camera and post-flight video processing algorithms.

JAPANESE PILOTS' CAREERS SET FOR TAKE OFF AT AVALON
A new advanced pilot training program for All Nippon Airways took off today at Avalon Airport, signalling another major initiative for Victoria's aviation and aerospace industries.
The Minister for Industry and Employment, Mr Gude, told a welcoming ceremony at Avalon that the program recognised the airport's potential and reflected Government recognition of these key industries in last week's Industry Statement.
"ANA, as Japan's largest airline, has shown its commitment to Avalon by signing a three-year contract with AeroSpace Technologies of Australia (ASTA), which leases the airport from the Commonwealth Government," Mr Gude said.
"It has a further six-year extension available, which I hope will be taken as the State builds on its leading market share of the aviation and aerospace sectors."
ASTA's subsidiary, ASTA Aircraft Services, which already provides maintenance work for ANA's Boeing 747s, will contract line maintenance work for the pilot training aircraft.
ASTA's presence in the industry has increased significantly. Since 1989 ASTA has increased its sales revenue by 65% and tripled its exports, which now make up nearly 80% of its business.
"The Government welcomes ASTA's performance in the context of its goal for sustained growth and increased job opportunities for Victorians," Mr Gude said.
"ASTA is playing its part in the recovery and we are pleased to be able to support it in areas such as infrastructure and research. The Government was also pleased to play a role in negotiations with ANA for the pilot training program.
"I find it extremely gratifying that an airline of ANA's reputation and stature has chosen Avalon to undertake its pilot training program. It is another initiative which is putting Geelong back on the map as a centre of industrial and commercial activity."
Mr Gude said the support of the City of Greater Geelong and the Civil Aviation Authority had been fundamental in attracting ANA and he looked forward to ongoing assistance from these bodies to attract more investment opportunities.

On 22 October 2005, an Airbus A319-100 being operated by British Airways on a passenger flight from London Heathrow to Budapest experienced the sudden onset of a major electrical failure when passing FL200 in night Visual Meteorological Conditions (VMC). The crew recovered the situation sufficiently to decide, after consulting Company Maintenance Control, that it was appropriate to continue to their intended destination. ATC were not informed of the situation encountered. The action taken by the crew after the flight in respect of the failure was ineffective and the Operator remained unaware of the safety and airworthiness significance of it. As a result, the proper reporting action was not taken, thus delaying the start of an Investigation.
The Aircraft Accident Investigation Branch (UK) (AAIB) only became aware of the event six days after it had occurred through the UK CAA MOR Scheme. Once the significance of the occurrence had been recognised, an Inspector’s Investigation had been commenced.
It was established that the major electrical failure had occurred without prior warning and with AP and A/T engaged and with the aircraft commander acting as PF. It resulted in the loss or degradation of a number of important aircraft systems including, according to the crew, the blanking of the PFDs and NDs at both pilot positions and the upper Electronic Centralized Aircraft Monitor (ECAM) display. Uncommanded disconnect of the AP and A/T occurred and it was reported that the No 1 VHF radio and the crew intercom became inoperative and most of the flight deck lighting went out. It was reported that the passenger cabin lighting had gone out “momentarily” and that the emergency lights had come on. There were several other concurrent but more minor failures.
The PF had maintained control of the aircraft by reference to the visible night horizon and the standby instruments, although the latter were reported to have been difficult to see in the poor light. The First Officer had actioned the abnormal checklist actions which appeared on the remaining (lower) ECAM display, which was the only Electronic Flight Instrument System display still functioning. It was reported that most of the affected systems had been restored after approximately 90 seconds, following the selection by the First Officer of the AC Essential Feed switch to ‘Alternate’.
Two Special Bulletins S2/2005 and S3/2006 were published during the course of the Investigation in November 2005 and April 2006 respectively.
After an in depth Investigation of the electrical systems on the aircraft type, the formally-stated Conclusions of the Investigation in respect of the loss of airworthiness were that:
- The aircraft suffered the loss of the left electrical network, for reasons which could not be established. A possible explanation is the detection of a false DP2 condition by the No 1 Generator Control Unit, but this could not be confirmed.
- The loss of the left electrical network caused various systems powered by the left network to either cease operating, or become degraded. These systems included, most notably, the autopilot, the autothrust system, the Captain’s and Co-pilot’s Primary Flight and Navigation Displays, the upper ECAM display, most of the cockpit lighting, including the integral lighting to the instruments and standby instruments, the VHF 1 and VHF 2 radios and the ATC 1 transponder.
- The majority of the aircraft systems were recovered after approximately 90 seconds, after selection of the AC ESS FEED switch, in accordance with the ECAM procedure. AC BUS 1 was recovered after approximately 135 seconds, by cycling of the No 1 generator switch.
- This and other similar incidents show that there is at least one unforeseen failure mode on A320 family aircraft, which can cause the simultaneous loss of the captain and co-pilots electronic flight instruments and the upper ECAM display.
- Aircraft equipped with an electromechanical standby horizon and not provisioned with the ISIS wiring configuration have a single power supply to the standby horizon, from the DC ESS bus. If this incident had occurred to such an aircraft, the standby horizon would have been unpowered and become unusable after approximately five minutes.
- The A318/A319/A320/A321 MMEL allows the aircraft to be dispatched with the lower ECAM display inoperative. In this case, it was the only display available and presented the list of actions, which enabled the crew to recover most of the failed systems.
- Trials showed that in night conditions, there may be insufficient light available to see the standby instruments following the loss of the left electrical network, particularly if the cockpit dome light is off.
The formally-stated Conclusions of the Investigation in respect of the response to the occurrence and the organisational context of that response included:
- The flight crew had not received any formal training on how to operate A320-family aircraft by sole reference to the standby instruments.
- The commander did not record the full details of the incident in the aircraft technical log, however he did record this information on the Air Safety Report which he filed.
- The information contained in the ASR raised by the commander should also have been reflected in the aircraft technical log. The technical log did not contain important details of the incident; as a result it reflected only minor defects which were rectified without appreciation of the importance of the serious incident which had occurred.
- The faxed copies of the Air Safety Report raised by the commander were not received by the airline’s Flight Operations Safety Department, or the department responsible for entering the incident data on to the electronic safety management database. As a result of this and of the minimal information contained in the Technical Log, the significance of the incident was not fully understood until the original copy of the ASR arrived in the post at London Heathrow.
- The engineer in Budapest (who was not an employee of the airline), did not investigate the symptoms of the incident which were reported to him verbally by the commander and which were also recorded in the Air Safety Report.
Conclusions drawn after analysis of the recorded flight data were as follows:
- Airbus found a failure mode by which the co-pilot’s ND and PFD could have been switched from the functional DMC2 to the failed DMC3 whilst leaving the lower ECAM linked to DMC2, however, no link has been found between this failure mode and the failure of power on the aircraft.
- Because the mechanism by which the power failure on the Captain’s side resulted in the additional loss of the Co-pilot’s instruments is not known, it cannot have been considered when analysing failure modes for compliance with requirements.
- The system BITE designs have been improved to better capture this type of failure. BITE is not recorded by the FDR. Detailed evidence may be lost in the event of an accident caused by the failures involved in this incident.
- The display behaviour was not apparent from the recorded data. Only the crew observations revealed the extent of the problem. This evidence may be lost in the event of an accident.
- A crash-protected image recording of the instruments would have provided more detail to this investigation and provided crucial evidence that may otherwise have been missing had crew observations not been available.
It was not possible to determine the origin of the investigated Serious Incident due to a lack of available evidence but upon completion of the Investigation the following Causal Factors were identified:
- The aircraft suffered the loss of the left electrical network, resulting in loss of the captain’s PFD and ND, and the upper ECAM display, for reasons which could not be determined.
- A co-incident failure caused the co-pilot’s Primary Flight Display and Navigation Display to blank or become severely degraded, at the same time as the loss of the left electrical network. The origin of the co-incident failure could not be identified.
The following four Safety Recommendations were made during the course of the Investigation and published in April 2006 in Special Bulletin 3/2006:
- that the aircraft manufacturer, Airbus, reviews the existing ECAM actions for the A320‑series aircraft, given the possibility of the simultaneous in-flight loss of the commander’s and co‑pilot’s primary flight and navigation displays. They should consider whether the priority of the items displayed on the ECAM should be altered, to enable the displays to be recovered as quickly as possible and subsequently issue operators with a revised procedure if necessary. [2006-051]
[It was noted that Airbus had concluded that it would not be acceptable to change the priority of the ECAM action items for a number of (stated) reasons.]
- that the aircraft manufacturer, Airbus, should review the A320-series aircraft Master Minimum Equipment List Chapter 31, INDICATING/RECORDING SYSTEMS and reconsider whether it is acceptable to allow the ECAM lower display unit to be unserviceable. They should amend the requirement, as necessary, to take account of the possibility of the simultaneous in-flight loss of both the commander’s and co-pilot’s primary flight and navigation displays and the ECAM upper display. [2006-052]
[It was noted that Airbus had subsequently reviewed the content of the A320 series MMEL in respect of dispatch with the lower ECAM display inoperative and updated it to include the condition that an operational test of the AC Essential bus transfer function and indication must be performed once per day if the lower ECAM is inoperative. However, the AAIB noted that the Recommendation had been made “to ensure that the operating crew would always have information presented on ECAM as to the actions required to recover the systems should a similar event occur” which had not been addressed by the Airbus response and were then advised that Airbus proposed to further amend the A320 series MMEL in respect of dispatch with the lower ECAM inoperative “to remind crews of the necessary recovery action should the AC ESS bus, and therefore all DUs be lost”]
- that the aircraft manufacturer, Airbus, should identify those aircraft with the single power supply to the standby artificial horizon and advise the operators of the potential implications of this configuration. [2006-053]
[It was noted that Airbus had since advised operators that “for aircraft without the ISIS wiring configuration to the standby instruments, the standby horizon may be unusable after five minutes if the DC ESS bus is lost”]
- that the aircraft manufacturer, Airbus, revises the information about the power sources for the standby artificial horizon provided in Flight Crew Operating Manuals for the A320-series aircraft to reflect the actual status of the aircraft to which they apply. [2006-054]
[It was noted that Airbus had since updated the A320 series FCOM to reflect the different power supply configurations for the standby horizon.]
Upon completion of the Investigation, nine further Safety Recommendations were made as follows:
- that the European Aviation Safety Authority should, in consultation with other National Airworthiness Authorities outside Europe, consider requiring training for flight by sole reference to standby instruments for pilots during initial and recurrent training courses. [2007-062]
- that Airbus should introduce a modification for A320 family of aircraft which have the pre-ISIS wiring configuration for the standby instruments, in order to provide a back-up power supply which is independent of the aircraft’s normal electrical power generation systems. [2007-063]
[In publishing this Recommendation, it was noted that since the issue of Special Bulletin 3/2006, “Airbus has advised that a modification which provides an automatic reconfiguration of the power supply to the AC ESS bus in the event of AC 1 bus failure had been issued which “largely satisfies the intent of” this Recommendation.]
- that the European Aviation Safety Agency should mandate either Airbus Service Bulletin SB A320-24-1120 or the provision of a back-up power supply for the standby horizon which is independent of the aircraft’s normal electrical power generation systems, on A320 family aircraft. [2007-064]
- that in order to ensure that the standby instruments on A320 family aircraft remain adequately illuminated following the loss of the left electrical network, Airbus should introduce a modification to provide a power supply for the standby instrument integral lighting which is independent of the aircraft’s normal electrical power generating systems. [2007-065]
[In publishing this Recommendation, it was noted that in response to an earlier draft of it Airbus had issued modifications which would ensure provision of a backup supply to the cockpit floodlight above the standby instruments].
- that the European Aviation Safety Agency should mandate the provision of a power supply for the standby instrument integral lighting which is independent of the aircraft’s normal electrical power generating systems, on A320 family aircraft. [2007-066]
- that Airbus should conduct a study into the feasibility of automating the reconfiguration of the power supply to the AC Essential bus, in order to reduce the time taken to recover important aircraft systems on A320 family aircraft following the loss of the left electrical network. [2007-067]
[In publishing this Recommendation, it was noted that in response to an earlier draft of it, Airbus had issued a modification to provide automatic reconfiguration of the power supply to the AC ESS Bus in the event of AC BUS 1 failure.]
- that Airbus, in conjunction with the Generator Control Unit (GCU) manufacturer Hamilton Sundstrand, should modify the A320 family GCUs to provide the capability to record intermittent faults and to reduce their susceptibility to false differential protection trips. [2007-069]
- that the International Civil Aviation Organisation should expedite the introduction of a standard for flight deck image recording, and should encourage member states to provide legal protection, similar to that for cockpit voice recordings, for such image recordings. [2007-070]
- that British Airways should review the advice given to flight crew concerning aircraft Technical Log entries, where an Air Safety Report (ASR) is also raised, to ensure that the aircraft Technical Log fully records the details of serious incidents and to ensure, as far as possible, that ASRs are received by the Flight Operations Safety Department in a timely a manner, irrespective of where the ASR is raised. [2007-071]

While the fast-approaching ADS-B Out mandate does not apply to drones, there’s still a strong case for integrating the technology in both manned and unmanned operations. AOPA members can purchase uAvionix solutions for both kinds of aircraft at a discount.
Manned aircraft owners have just a few weeks left to equip before the January 1, 2020, ADS-B Out deadline, and it’s a hot topic in aviation. So are drones, and not always for the best reasons. Headlines around the world report both the benefits and dangers of this incredible new technology; from medical and blood supply delivery in Rwanda to airport shutdowns in London.
There is a critical intersection of these two topics: Drone technologies are evolving each year, and much of the effort to safely integrate manned and unmanned aircraft in the same airspace focuses on detect-and-avoid (DAA) technology. Just as manned pilots must “see and avoid” other aircraft, drones will need to be able to avoid colliding with other aircraft, and that needs to be as automated as possible. There are dozens of DAA technologies in development ranging from computer vision systems to radar, electro-optical systems, and even microphones tuned to listen for nearby aircraft. But many of these systems are too big, too expensive, or simply don’t perform well enough yet.
Right now, the most cost-effective and robust DAA solution available is ADS-B receivers (or ADS-B In) on the drone itself, enabling the remote pilot to be aware of any nearby aircraft broadcasting ADS-B Out.
uAvionix leads the industry when it comes to ADS-B technology for both general aviation and drones.You may know uAvionix as the manufacturer of tailBeacon and skyBeacon—the lowest-cost ADS-B Out solution for GA aircraft.You may not know that we also develop ADS-B In modules for drones.
There has been a lot of movement just this year in leveraging ADS-B as a key DAA solution. Here are some key activities:
In the drone industry, it is becoming the culturally responsible thing to integrate ADS-B as the DAA technology of choice. This is great news for pilots, because drones are very hard to see (and avoid) from the cockpit, and situational awareness for all will dramatically reduce risk. Remote pilots must always yield right of way to any manned aircraft, and that’s not always easy when trees, buildings, and other obstacles can obscure an approaching aircraft. Eyes and ears alone may not always leave a remote pilot enough time to get out of the way of an approaching aircraft. Just like in the cockpit, ADS-B In on your drone gives you precious minutes to detect, decide, and act. The more operators participate in ADS-B, the safer everyone will be. | Yes |

A plane's wing was seen "coming apart" in footage captured by a passenger on a United Airlines flight.
The plane was forced into an emergency landing after the Boeing 757-200's wing started to break apart.
Kevin Clarke, one of the 165 passengers aboard the flight from San Francisco to Boston, filmed the wing while in the air.
He said: “Just about to land in Denver with the wing coming apart on the plane.
“It came apart when we took off in San Francisco, and we’re just about on the ground. Can’t wait for this flight to be over.
They’ve got another plane waiting for us. Touchdown any second, and the nightmare will be over.”
Speaking to WCVB, he added that he felt “this incredible loud vibration” on the plane.
Clarke continued: “It was like, ‘What was that?’”
Speaking to NBC Boston, he described how the pilot walked out into the cabin to examine the damage.
Clarke went on: “He goes behind me and I was kind of sleepy, so I wasn’t paying much attention at that point, but then he goes back to the cockpit and he comes on the PA and says, ‘We’ve discovered we have some damage on one of the front flaps and we’re going to divert to Denver and put you all in a different plane.'"
Another passenger from the flight shared a photo of the wing on Reddit.
They shared the picture with the caption: “Sitting right on the wing and the noise after reaching altitude was much louder than normal. I opened the window to see the wing looking like this.
“How panicked should I be? Do I need to tell a flight crew member? I’ll be very relieved once we land.”
The plane made its emergency landing safely in Denver at 5:15 pm Monday.
United Airlines said in a statement: “United Flight 354 diverted to Denver yesterday afternoon to address an issue with the slat on the wing of the aircraft.
“The flight landed safely and we arranged for another aircraft to take our customers to Boston."
What caused the damage remains unclear with an investigation underway. | Yes |

Wherever you are in the world, the National Aeronautics and Space Administration (NASA) is giving you an opportunity to “fly along” to the Red Planet—even before the actual, most-anticipated human mission takes place. On Wednesday, the independent agency invited space enthusiasts to be part of the Mars 2020 rover just by filling out this online form.
Now you’re probably wondering how this trip is even possible?
NASA explained that the names will be etched on a dime-sized chip with lines of text smaller than one-thousandth the width of a human hair (75 nanometers). The Microdevices Laboratory at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, will use an electron beam to engrave about a million names onto a silicon chip that will be affixed to the rover. This means that even though you’re not in the spacecraft physically, you’re already part of the mission…in spirit.
Upon signing up, the participants will then receive a “boarding pass” and “frequent flyer points”, proof that you have already been included in the exciting exploration.
According to NASA, the Mars 2020 rover will represent the beginning of the human race’s journey to another planet. The agency also added that the main purpose of this rover is to “search for signs of past microbial life, characterize the planet’s climate and geology, collect samples for a future return to Earth, and pave the way for human exploration of the Red Planet.”
The said exploration vehicle is scheduled to launch as early as July 2020 and the spacecraft is expected to touch down on Mars in February 2021.
Although this offer is open to all, the entries will still have to be reviewed before they can have their names on the rover. You still have until September 30th to participate.

Sharp chest pains. Myocarditis and pericarditis. Heart attacks. Strokes and subsequent blindness.
These are just some of the many COVID-19 vaccine-related adverse events reported by commercial airline pilots and by a growing number of advocacy groups representing aviation industry workers.
According to these individuals and groups, the number of pilots speaking out about their vaccine injuries is dwarfed by the number of pilots who are still flying despite experiencing concerning symptoms — but not speaking out because of what they describe as a culture of intimidation within the aviation industry.
These individuals fear they will lose their jobs and livelihoods in retaliation if they reveal their symptoms or go public with their stories, sources told The Defender.
Still, a growing number of pilots are coming forward.
Last month, The Defender published the accounts of several pilots — and of the widow of a pilot who died from a vaccine-related adverse event.
Since then, more pilots have shared their stories, including one who is currently flying for a commercial airline.
A growing number of advocacy organizations, representing workers across the aviation industry and in several countries, are joining these pilots in speaking out. | Yes |

U.S. vs. China: the new space race is on
Carol Ingley, President, Media Mogul Enterprises
Digital Trends and Key Words: space industry, space launches, U.S. space industry, China's space industry, private sector space industry, SpaceX, Blue Origin, space race, launch vehicles, payloads, space stations, lunar stations, NASA, Artemis
A new rivalry has emerged in the space industry. In the 1950s and 1960s, the hot rivalry was between the U.S. and Soviet Union (now Russia). The U.S. pulled ahead in the space race with the manned Apollo 11, landing on the moon in 1969. Meanwhile, the Soviet space program and space agency got mired in bureaucracy. They never made it to the moon. It's decades later and now a space rivalry has emerged between the U.S. and China.
There’s an expression that may be telling in the space race between the U.S. and China. The expression is: the race is not always to the swift, nor the battle to the strong, but that is the best way to bet.
Yet putting a big value on the swift and strong may not be the best way to bet when it comes to the space industry. The expression actually changes the meaning from the Biblical verse upon which it is based. That verse says: “The race is not given to the swift or to the strong but to the one who endures to the end.” Will this space race be about being fast and being strong or will it be about enduring to the end, along the lines of the lesson learned from the tortoise and the hare fable – slow but sure wins?
Big Ticket Items
Getting to space is expensive and that expense never lets up. The hardware that is required to participate in the space race has always been capital intensive. A short list of these big ticket items includes:
Non-reusable launch vehicles: example rockets
Reusable launch vehicles: example space shuttle and SpaceX’s Falcon
Payload: carried by the launch vehicle including satellites, space exploration tools, spacecraft carrying humans, animals, or cargo.
Lunar Bases: a facility on the surface of the moon, allowing human activity on the Moon.
Space Telecommunications Systems: telecommunications systems in space such as StarLink
Space Stations: It is a spacecraft that offers support for astronauts in space for an extended amount of time, often for many months.
Mission Control Center: a facility that manages and controls space flights.
Exploration Tools: space telescopes, intelligent robots, super-high-speed communications, sophisticated detectors, probes and instruments
Not every country can compete in this very expensive space game with the above highly expensive components. It’s not just making the components but having them evolve and change with the market needs, meaning the expense of research and development is also part of the cost package.
Four Top Countries
Most countries or regions of the world are not capable of completing space launches. The top four countries/regions who are capable of space launches are: the U.S., Russia, China and Europe.
For this launch capability, the U.S. has the space agency NASA (which has recently partnered with the U.S. Space Force) with a robust private sector participation by SpaceX with its own capability to complete space launches. The U.S. has also succeeded in launching astronauts into space, often to the International Space Station, as well as being the first (and still the only) to have astronauts walk on the moon.
Russia has launch capability with ROSCOSMOS. In 2015, ROSCOSMOS's merged with another government entity, resulting in its current form as a Russian nationalized agency. Russia has also succeeded in launching cosmonauts into space, primarily to the International Space Station.
China has two space agencies. The China National Space Administration or CNSA is responsible for civil space administration and international space cooperation. The second agency is the China Manned Space Agency or CMSA. It is responsible for the administration of the China Manned Space Program.
In Europe, twenty-two European countries form the European Space Agency (ESA) headquartered in Paris, France. ESA is dedicated to the exploration of space. Ariane 5 is the launch vehicle used by ESA, located in French Guiana. The launch vehicle is operated by Arianespace for ESA. ESA has not yet put astronauts into space.
Truth or Fiction
A rivalry has now developed between the U.S. and China. Both of these countries’ space programs are discussed, first the U.S. and then China.
But first, is that statement reflect truth or is it fiction? Is it a rivalry? Some say truth, specifically. Gen. David D. Thompson, vice chief of space operations for the U.S. Space Force. Recently, he declared vehemently, “The fact, that in essence, on average, they [the Chinese] are building and fielding and updating their space capabilities at twice the rate we are means that very soon, if we don’t start accelerating our development and delivery capabilities, they will exceed us.”
But some say fiction. Money talks in the space industry. Space funding in China has grown significantly but it stood at $8.9 billion in 2020 compared with the U.S. funding of $48 billion. More significantly is the fact that China is far behind the U.S. in the participation of the private sector in space. Still, China could have an ace up its sleeve by partnering with Russia. They have been cooperating for some time.
U.S. Space Program
In the U.S., NASA’s new mission is named Artemis, the twin sister of Apollo and the goddess of the moon in Greek mythology. The Artemis mission is lunar at first and then will shift to Mars.
During a news conference in August 2022, Bill Nelson, a NASA administrator, explained, "We're going back to the moon in order to learn to live, to work, to survive." .He went on to clarify that it is all about how to keep people alive in hostile environments as well as learning how to use planetary resources. The plan is to establish a sustained human presence on the moon. As that plan progresses, an orbiting lunar outpost called the Gateway will be put in place. At some point, the focus will turn to Mars.
In the private sector, which is very active in the U.S. for the space industry, the three largest defense contracting companies are Lockheed Martin, Northrop Grumman and Raytheon Technologies. These companies and many others are packed with resources and experience in the space industry.
The U.S. private sector for space, though, has changed rapidly over the past decade or so. Two newcomers are SpaceX and Blue Origin. These companies are creating innovative technologies and plan themselves to develop industry in space. SpaceX is likely the best known newcomer. Elon Musk started SpaceX with his eye on creating human colonies on Mars. But he is interested in industry on the planet as well.
Much of the innovative future forthe U.S. space programs may well come from the private sector. NASA’s plan is to partner with that private sector whenever possible. How the partnerships between NASA and the private sector will all shake out is still unknown, it should be noted.
Chinese Space Program
According to Chrisotpher Newman, a professor at the U.K.’s Northumbria University, China’s ambitions are big. First, the country wants to be the superpower in science and technology. Second, by 2045, China wants to be the leading space power.
Big ambitions require big moves. In December 2020, China went to the moon. Its lunar mission returned to earth with moon rocks. It was a first for China. More telling was that it is evidence of China moving forward into space travel and exploration.
The U.S. government, as many are familiar with, owns the Global Positioning System or GPS. Now China has finished its own satellite navigation system. The system is named Beidou.
In 2021, a crewed mission from China landed at their space station, another bold move.
Like the U.S., the Chinese eyes are fixed on the red planet. Their goal is to land humans on Mars by 2033.
Meanwhile, the Chinese have been madly filing patents related to space and space travel. If the patents set the standards, China could end up being a gatekeeper to space development in the future
What’s missing in China is a big participation by the private sector. That could prove key to who wins this race. Historically, in the U.S., the private sector moves faster and with more innovation than the government. The U.S. private sector has aggressively moved forward in the space industry, with SpaceX standing out, making big splashes with success after success.
According to Scott Pace, director of the Space Policy Institute at The George Washington University’s Elliott School of International Affairs, as told to CNBC: “The United States has a strong policy for space exploration, a clear direction, and capable allies and partners. The challenge for the United States is not so much what China does, but how well and how quickly the United States implements its own plans.”
So back to the hare and tortoise fable. The tortoise just plods along and wins. The hare zips ahead but gets distracted. But that’s a short race in the fable. This is a very, very long race. The winner may be a combination of the two: the country with the hard drive forward (hare-like) with a steady pace over a long period of time (tortoise like but a longer race) wins the crown.

Today, August 12, is the first-year anniversary of the launch of NASA’s Parker Solar Probe (PSP), which is already revolutionizing our understanding of the nearest star, our Sun. PSP is conducting multiple close flybys, coming closer to the Sun’s surface than any other spacecraft before.
Scientists and other mission team members got a pleasant surprise when the final data was sent back to Earth from the previous two flybys, on May 6, 2019: the total amount of data turned out to be 22 gigabytes. That’s 50% more than had been expected.
The data was received on Earth at Johns Hopkins Applied Physics Laboratory (APL), in Laurel, Maryland.
“We’re very happy,” said Nicky Fox, director of NASA’s Heliophysics Division at NASA Headquarters in Washington, D.C. “We’ve managed to bring down at least twice as much data as we originally suspected we’d get from those first two perihelion passes.”
The additional data is thanks to the telecommunications system on the spacecraft performing better than pre-launch estimates said it would. The mission team was able to maximize the data download after determining that the telecom system could effectively deliver more downlink opportunities.
“All of the expected science data collected through the first and second encounters is now on the ground,” said Nickalaus Pinkine, Parker Solar Probe mission operations manager at APL. “As we learned more about operating in this environment and these orbits, the team did a great job of increasing data downloads of the information gathered by the spacecraft’s amazing instruments.”
The mission team was able to send instructions to the probe to record and send back extra science data from the second flyby. This is an additional 25 gigabytes of data that is being downlinked between July 24 and Aug. 15, 2019.
Of course, as with any mission, the more data the better.
“The data we’re seeing from Parker Solar Probe’s instruments is showing us details about solar structures and processes that we have never seen before,” said Nour Raouafi, Parker Solar Probe project scientist at the Johns Hopkins Applied Physics Laboratory, which built and operates the mission for NASA. “Flying close to the Sun — a very dangerous environment — is the only way to obtain this data, and the spacecraft is performing with flying colors.”
PSP made its second close flyby of the Sun on April 3, 2019. PSP passed through the outermost layers of the Sun’s atmosphere, the corona, at 213,000 mph, coming within 15 million miles of the Sun’s surface itself. Closest approach, called perihelion, occurred at 6:40 p.m. EDT.
The first close flyby occurred on November 5, 2018.
PSP’s mission is to complete multiple close flybys of the Sun, to try to solve some long-standing solar mysteries such as how the solar wind accelerates particles, and why the Sun’s corona is so much hotter than its surface. The three main science objectives include:
- Trace the flow of energy that heats and accelerates the solar corona and solar wind.
- Determine the structure and dynamics of the plasma and magnetic fields at the sources of the solar wind.
- Explore mechanisms that accelerate and transport energetic particles.
It has already flown closer to the Sun than any other previous spacecraft, passing through the Sun’s outer atmosphere, the corona. The previous distance record was held by the Helios 2 probe, which passed about 27 million miles from the Sun, in 1976. Four different suites of scientific instruments take images and other data during the flybys.
PSP will perform 24 flybys of the Sun in total, each one a bit closer than the previous one. Its third solar encounter will begin on Aug. 27, 2019; the spacecraft’s third perihelion will occur on Sept. 1.
You can view the entire mission timeline here.
The data from the flybys will also be useful in helping to protect satellites and power grids on Earth, as well as future astronauts.
In 2025, at the end of the mission, PSP will pass only 3.83 million miles from the surface of the Sun, enduring extreme temperatures of nearly 2,500 degrees F.
“It’s going to help us be able to predict solar flares,” NASA administrator Jim Bridenstine said last March at a congressional subcommittee in Washington, D.C. “It’s going to help us predict coronal mass ejections potentially that could be very damaging to astronauts in deep space as we return to the moon and eventually go on to Mars. So we need to be able to predict those to protect human life into the future.”
PSP was formerly known as Solar Probe Plus, but was renamed for solar scientist Eugene Parker in 2017. This is the first NASA mission that has been named for a still-living individual.
More information about Parker Solar Probe is available on the mission website.

Hi all. I’m new to the site and I’ve spent the last few months doing a lot of research on drones. During the pandemic, I purchased a DJI Phantom 4 and had fun learning to fly.
I have a background in cyber security and Linux/software development. I want to put together a Pixhawk 4 drone and run the PX4 flight stack. My goal is to learn the inner workings of an open source drone and potentially develop some software. I'm particularly interested in imaging and data analystics.
I’m currently considering a Holybro S500 kit with a FrSky Taranis X9D transmitter. I'd like to add a camera and companion computer like an RPi. I'm looking for suggestions from anyone with a similar rig. | Yes |
With the current methodology of runway condition monitoring, when a runway is contaminated by ice...
Global Runway Reporter is an advanced software designed to make runway inspection and maintenance effortless and efficient, as well as Global Reporting Format standardisation.
Get alerted when inspection is timely. Easily report contaminants directly from the inspection vehicle with mobile software. Explore with limitless visual analytics. Customise analysing tools and perform analyses in just a few clicks. From the biggest airports to the smallest ones uses Global Runway Reporter to report runway conditions and generate consistent SNOWTAM syntax.
The three modules cover the whole process of runway reporting and make it simple and safe. Alerter improves cost-efficiency due to better timing of efforts and gives alerts when PIREP or aeroplane RWYCC differ current runway condition. Mobile software gives guidance for the user for assessment and visualises reported conditions in real time. Web software allows history browsing and running unlimited analysis from the database.
Alert benefits include:
- Improved cost efficiency due to better timing of efforts
- Alerts when regulatory or aircraft performance limits are passed
- Alerts when PIREP or aircraft RWYCC differ from current runway condition
Mobile benefits include:
- Runway Condition Reporting in accordance with ICAO, FAA and EASA
- Assessment guidance and real-time visualisation of reported conditions
- Consistent SNOWTAM syntax and regulatory archiving
Web benefits include:
- Able to view real-time status of all your runways
- Browsing of report history
- Large scale of customisable analysing tools
ICAO (International Civil Aviation Organization) has put a lot of effort to build up a harmonised reporting system called Global Reporting Format (GRF). The purpose of this is that no matter where the pilot is landing, he or she is getting the runway report in same format and in a way that the reported condition is the same in all airports. This new format replaces all existing formats in November 2020. All airports should report runway conditions according to this Global Reporting Format by then. So all airports should report runway conditions and with Global Runway Reporter software this can be easily done in a way that always follows ICAO standards.
Difference between landing and take-off
The new RCAM runway reporting table is designed for landing airplanes. The importance of landing safety can’t be underestimated but this generates other issues which are not discussed because of lack of understanding of this topic and that is the takeoff. When using the same Runway Condition Code for landing and takeoff can be very dangerous in certain situations. And those situations occur when we report slippery conditions, which generate low Runway Condition Code but are still thick, which also generate drag when an aircraft is taking off. This can lead to catastrophic overruns if, for example, the engine breaks during acceleration.
There are multiple situations when the information generated by the RCAM table is not enough for safe takeoff. In our Global Runway Reporter software, there is an in-built feature that takes care of this issue. Thanks for our long history of providing aircraft performance software we have the understanding needed to tackle this topic. We report runway conditions in a way that we are able to calculate the most significant contaminant for takeoff. This increases safety when we don’t compromise takeoff safety when reporting landing conditions. Aircraft companies are very happy with this when our provided information makes their decision-making process easier when calculating the takeoff performance parameters.

Nonlinear Interaction of a 3D Kinetic Alfv\ en Wave with a Null Point and Turbulence Generation in the Solar Corona
In the present paper, we have studied nonlinear kinetic Alfv\ en waves (KAWs) in the vicinity of a null point. We have considered the nonlinearity due to ponderomotive effects associated with KAWs in the solar corona. A 3D model equation representing the dynamics of KAWs is developed in this null point scenario. Using numerical methods, we have solved the model equation for solar coronal parameters. The pseudospectral method and the finite difference method have been applied to tackle spatial integration and temporal evaluat ...

Antenna scattering measurements using a scaled 3-D printed spacecraft model
A method to measure an antenna s performance when mounted to an electrically large and complex-shaped spacecraft is described. In the past, either time-intensive numerical simulations or antenna range measurements of an expensive full-scale model of the spacecraft were used to determine the antenna s performance. An alternative method fabricated a reduced-size scaled spacecraft model using 3-D printing processes. The antenna is also reduced in size by the same scale factor as the spacecraft, but the frequency of operation is ...

Leasing Company And Boeing Expand Their Partnership With AMX
International Lease Finance Corporation (ILFC), a wholly owned subsidiary of American International Group, announced Wednesday it has completed an agreement to expand its partnership with Grupo Aeromexico by adding two additional new Boeing 787-8 aircraft bringing the total leased from ILFC to five.
"The addition of these two Boeing 787 aircraft to our current fleet of five, two which were ordered from Boeing and three previously leased from ILFC, is very positive news for Grupo Aeromexico, as part of our expansion plan to service international markets. These aircraft will be deployed on our long-haul routes, ultimately replacing 767 aircraft and allowing us to continue providing high-quality service while proudly representing Mexico worldwide," said Andres Conesa, CEO of Grupo Aeromexico.
ILFC Chief Executive Officer Henri Courpron commented, "Aeromexico was ILFC's first customer. We appreciate their confidence in ILFC over the last 38 years. This new transaction is a symbol of the important strategic partnership between Aeromexico and ILFC."
The aircraft, equipped with GEnx engines, are scheduled for delivery in the first half of 2014.

It’s a milestone in a formidable plan to launch new spacecraft, assemble a lunar space station, and bring humans back to the Moon for the first time since the end of the Apollo program, when astronauts Gene Cernan and Harrison Schmitt were the last to set foot on the dusty regolith moon.
Artemis 1 will mark the inaugural launch of a 32-story rocket called the Space Launch System, topped by the Orion space capsule.
The capsule will fly within 62 miles of the lunar surface while deploying small spacecraft for research on and beyond the moon.
While this first flight will be unmanned, others with astronauts will follow in the years to come, and Orion is capable of carrying humans further than any spacecraft has flown before.
Although the important Artemis 1 mission includes some research objectives, it serves as both a technology demonstration and a symbol. “For all of us who gaze at the moon dreaming of the day humanity returns to the lunar surface, we are coming back. This journey, our journey, begins with Artemis 1,” NASA chief Bill Nelson said during a a virtual press conference in early August.
The Artemis 1 launch period begins at the end of August, the NASA schedule will be from the morning of August 29, and the backup dates will be September 2 and 5.
If liftoff from NASA’s Kennedy Space Center in Florida, the moon flyby, reentry and crash of Orion off San Diego in October go as planned, the Artemis 2 will continue.
On a video of NASA – in English – is a good illustration of this decision.
During this first manned mission in 2024, four astronauts will perform a lunar flyby. Next is Artemis 3 in 2025 or 2026, the first moon landing since 1972, which will include the first woman to set foot on the moon.
Astronauts aboard Artemis 4 in 2027 will deliver the I-HAB module, which will become the main crew quarters aboard the Lunar Gateway station in its orbit around the moon.
The Artemis program has been running since 2017 and has cost around $40 billion so far.
Its main purpose will be to establish a sustained presence on the Moon in the form of a space station and lunar camp or colony, as part of NASA’s larger effort to prioritize human space travel.
“We are beginning a long journey of science and exploration,” Bhavya Lal, associate administrator at NASA, said at last week’s press conference. “We did our initial reconnaissance with robots and humans, and now we’re learning what we need to know so we can spend more time on the Moon and then prepare to go to Mars and beyond.”
Indeed, Artemis is part of NASA’s long-term “Moon to Mars” program, as the space agency plans to send astronauts to the Red Planet within 20 years.
“Everything we do on the lunar surface, we do to explore science, and we’re not just going to put up ‘flags and footprints’ as some call it. [Apollo]but also to test the systems that we will eventually need to reduce the risks of a human mission to Mars, ”explains Cathy Koerner, deputy associate administrator at NASA, based at the Johnson Space Center in Houston.

The U.S. National Aeronautics and Space Administration (NASA) is sending a humanoid robot, called Robonaut 2 (R2), to the International Space Station for the first time. R2 is made of aluminum and nickel-based carbon fiber and has more than 350 electrical sensors throughout its body. R2 is humanoid from the waist up and measures three feet, four inches tall and weighs 330 pounds. It can carry out preprogrammed orders by itself, once the orders are given. The objective is to help astronauts, not replace them, NASA says.
"While it might be just a single step for this robot, it's really a giant leap forward for tinmankind," says NASA's Rob Ambrose.
Once onboard the space station, R2 will undergo tests to see how it performs in weightlessness when attached to a fixed pedestal. NASA plans to send legs next year that will enable it to perform indoor chores, and future torso and computer enhancements will allow it to take space walks. R2 is expected to be onboard the space station until it stops operating sometime after 2020.

Hours Set for AirVenture LOA/LOOA Conversions
EAA Assists Warbird Owners With FAA Authorization
As reported last week, EAA has obtained an agreement with the Federal Aviation Administration that allows pilots of U.S. and non-U.S. surplus military aircraft and certain turbine-powered experimental amateur-built/experimental exhibition aircraft to operate beyond the July 31 deadline for Letters of Authorization (LOA) and Letters of Operational
Authority (LOOA) under certain specific circumstances. Affected pilots who plan to attend EAA AirVenture Oshkosh, July 27-August 2, can complete their LOA-LOOA conversion on convention grounds on Wednesday, July 28, and Thursday, July 29, at the Warbirds Aircraft Registration Building from 9 a.m.-noon and 1-4 p.m. (both days). Those wanting to convert their certificates at AirVenture must bring their full application package with them to the event.
Some Vintage Aircraft Can be Flown by Sport Pilots
Current vintage lightplane owners have been anxiously awaiting the final rule for light-sport aircraft, hoping that their particular airplane would fit within the guidelines. Joe Norris of EAA's Aviation Services compiled the following list of Type Certificated aircraft whose performance criteria, as documented within the Type Certificate Data Sheet, would allow the airplane to be operated by a sport pilot.
In the final rule, the slight increase in maximum gross weight to 1,320 pounds did allow a few more aircraft to meet the criteria.
Sport Pilot Takes Center Stage at EAA AirVenture
At EAA AirVenture Oshkosh 2004’s Sport Pilot Center, attendees can see a wide variety of light-sport aircraft on display. EAA members and visitors will have a great opportunity to examine and consider a nearly complete range of light-sport aircraft that will be available under the new rule.
Sport Pilot Instruction Seminar Planned by NAFI
A NAFI (National Association of Flight Instructors) workshop is planned for Friday, July 30, to gather several representatives of general aviation flight schools and the ultralight flight instruction community to design an agenda and procedures for a much larger NAFI Symposium to be held at EAA headquarters in Oshkosh in the early fall. The AirVenture workshop will also include EAA representatives Rusty Sachs, NAFI Executive Director; Timm Bogenhagen, EAA Information Services ultralight programs manager; and Dan Johnson, EAA’s SP/LSA marketing leader.
LSA Promotional Board to Meet at Oshkosh
A second meeting of the Steering Committee for the Light-Sport Aircraft (LSA) Promotional Board is planned for Thursday afternoon, July 29, during the EAA AirVenture Oshkosh 2004 convention. The board’s purpose is to reach out to the general public with news and messaging touting an easier way to become involved with aviation.
The sport pilot certificate and light-sport aircraft category provide an opportunity for people to get involved in aviation who, for a variety of reasons, did not previously. The LSA Promotional Board hopes to change that by developing a traveling exhibit for recreational trade shows (motorcycle, boat, RV, outdoor sports, and other "affinity" activities). Early response to the formation of an LSA Promotional Board has been enthusiastic.

training in order to earn their Aircraft and Power Plant (AP&P)
license. For more information, visit www.mooney.com.
Comp Air Jet Makes First Flight
Aerocomp’s Comp Air Jet (CAJ) made a 37-minute maiden flight on Tuesday morning, July 20, at approximately 10:45am local time. The flight departed from Florida’s Merritt Island Airport, circled the field then proceeded to the Space Coast Executive Airport where the longer runway was chosen for the first (2,000-foot) landing.
Test pilot Ron Lueck’s first impressions were very positive and encouraging. “Although the gear was not retracted on this flight, we still saw speeds of 157 knots at 92 percent n1,” he said. “Pitch, roll, and yaw control were positive and harmonious making the big plane easy to handle.”
The CAJ is a kit jet built of composite materials. It offers seating for 8 and a cruise speed of 320 knots. With a fuel load of 550 gallons the CAJ’s projected range is over 1,000 nm. More details will be posted as flight-testing progresses on the company’s website.

The publicity of the week is undoubtedly to credit Audi. Far from the “dieselgate”, Volkswagen’s subsidiary CSP ++ communicates on a brand new model of the Audi Quattro, an all-terrain model since it is designed to face the lunar tracks. The carmaker is sponsoring the German “Part-Time Scientists” team, which participates in Google Lunar XPRIZE, a challenge with $ 30 million in endowments. 5 teams are still in the race to the Moon and the Audi Lunar Quattro may well be the first private rover to put its wheels on the lunar surface.
A robot on the trail of the Apollo 17 lunar jeep
It was in 2007 that the Google Lunar XPRIZE was launched and about fifteen teams committed to the technical challenge posed by Google. If several prizes have been awarded at different stages of the competition, the ultimate goal and land a robot on the moon, then roll it at least 500 m on the lunar ground. A distance that will allow the robot to go to the landing site of the famous Apollo 17 mission and find the lunar jeep left by the American astronauts in 1972.
This will send high-resolution images to the Earth. 16 teams entered the competition, with American, European, Japanese and Malaysian teams. These teams are essentially made up of researchers, academics and few industrialists involved in this space competition. Audi has chosen to sponsor “Part-Time Scientists”, a team of 70 members, 35 of which are based in Germany. Financial support that allows the manufacturer to affix his logo to the robot created by these part-time scientists.
The Lunar Quattro was unveiled at the beginning of the year and the manufacturer is now testing his robot to check that it will withstand the extreme conditions of a lunar stay. To realize its rover, the engineers chose titanium and aluminum to lighten the robot to the maximum. In addition, this one was realized in 3D printing. The Top Gear website points out that a change in the design of the wheels, initially intended to improve the stability of the robot, reduced their weight by 8 kg.
The German team has already negotiated with SpaceX to board its robot on a Falcon 9 rocket. If the mission ends in 2017, as announced, it will be the first private mission to reach the Moon and, incidentally, the first Audi to ride on the lunar ground.

Radiation hard four-junction space solar cell based on GaInAsP alloys
Electric orbit raising increases the radiation dose for space solar arrays significantly. This leads to the need for a more radiation resistant, highly efficient space solar cell. We propose a new wafer-bonded 4-junction structure which allows reaching begin-of-life efficiencies up to 34.7% (AMO) and efficiencies up to 30.8% (AMO) after 1*10 15 cm -2 1-MeV electron irradiation. The high radiation hardness is a result of specific material properties of InP-rich compounds which benefit from significant defect annealing under typical operating conditions in space. A new four-j unction space solar cell, based on high InP fractions containing GaInAsP and Ge is currently under development in the EU project RadHard and first devices achieve an efficiency of 21.4% (AM0) before irradiation. After irradiation, as expected, a strong annealing effect after 3 days at AM0 & 60°C is found for this device. Already at this early development stage 78% of the end of life open circuit target voltage of 3.09 V under AM0 has been reached. | Yes |
Goodrich Corporation today officially opened its new state-of-the-art nacelle integration facility, Goodrich Aerostructures Integration Services, Inc., in Everett, Wash. The 140,000-square foot building will be used for engine integration and final assembly of the nacelle inlet cowl for the new Boeing 787 Dreamliner.
Goodrich Aerostructures Integration Services is located at 2615 94th Street SW in Everett, adjacent to the company's Landing Gear facility, on property leased from the Snohomish County Airport. Goodrich owns the building.
Staffing for the new facility has already begun, with employment expected to total 35 by mid 2007. Employment levels will parallel 787 production and will increase in 2008 to about 80, mainly in production roles, adding to a substantial existing Goodrich presence in Snohomish County.
Goodrich was chosen by Boeing in April 2004 to provide the nacelles and thrust reversers for both the General Electric and Rolls-Royce engine options on the 787. The new building will incorporate the Lean design and manufacturing processes that Goodrich uses to produce world-class nacelle systems.
"This is an innovative site for an innovative airplane," said Curtis Reusser, president of Goodrich Aerostructures. "Lean principles have affected every aspect of this building, from the utility infrastructure to the flow of material through the building, enabling us to better meet the needs of the game-changing airplane program."
Another guiding principle of Lean design and manufacturing is collocation of customers and key suppliers. "By locating right next to 787 final assembly, we can better serve our Boeing customer with just-in-time delivery, close collaboration and real-time issue resolution," said Dave Castagnola, Goodrich Aerostructures Vice President for Boeing Programs. "This location also demonstrates our long-term Goodrich commitment to Boeing and the 787."
The integration of the Goodrich-built nacelles at the Everett facility will include installing nacelle hardware onto the engines that will enable the installation of the propulsion system directly onto the aircraft. Flight test units will be built in 2007 and full production will begin in 2008.
In addition to the nacelles and thrust reversers, Goodrich is providing the following technologies to Boeing for the Dreamliner: flight deck lighting system; cabin attendant seating; cargo system; wheels and electric braking system; exterior lighting; proximity sensor system; flight deck entry video surveillance system; fuel quantity indicating system and fuel management software. In addition, Goodrich has been selected by Rolls-Royce to provide the engine control system and sensor suite for the Trent 1000 engine, an engine option for the 787.

Nigeria’s airforce has said its plane, which crashed shortly after take-off from Abuja airport on Sunday morning – killing everyone on board – was on a mission to rescue the schoolchildren kidnapped last week.
A spokesman told CNN the aircraft was on surveillance operations in Niger State as part of efforts to rescue at least 42 schoolchildren and staff members taken by gunmen from the Government Science School Kagara last Wednesday. One student died during the attack.
Air Vice-Marshal Ibikunle Daramola told CNN on Monday afternoon that the air force had donated the military plane to a joint task force coordinating the rescue operation in Kagara.
“The rescue effort is being coordinated by a multi-agency team… the crashed aircraft was part of the air force’s contribution to the rescue mission,” he added.
Daramola told CNN that the airforce would continue to support the rescue operation.
He added that all families of the personnel have been informed, and an investigation launched.
The ongoing rescue efforts followed a directive by President Muhammadu Buhari to the armed forces and police to ensure all captives are rescued. | Yes |
UNITED STATES (VOP TODAY NEWS) — The landing module of the Mars InSight automatic station landed on Mars in the Elysium Planitia highland area. This was announced on Monday by the flight control center of the station during a live broadcast on the website of the National Aeronautics and Space Administration (NASA).
The landing on Mars took place at the estimated time of 14:54 by the US eastern coast. Seven minutes after landing, the device should send the first radio signal to Earth, and nine minutes later, after the dust settles in the landing area, begin the process of opening two solar panels.
The Elysian highland region, with a total area of 130 kilometers and 27 kilometers at 4 degrees north of the equator, was chosen for landing because it is a fairly flat part of the surface of Mars. On it are located volcanoes – the dome of Hecate, Mount Elysius and the dome of Labor.
In addition, in this area there are deep depressions – Cerberus furrow, Elysian furrow and Hephaestus furrow. The Mars InSight landing site is about 600 kilometers from Gale Crater, where the Curiosity rover was researching.
Communication with the landing module will be carried out both through the system of remote space communications, and through two Mars Cube One (MarCo) microsatellites, NASA representative Ann Marinan said.
Also, the landing module of the Mars InSight automatic station transmitted the first image from the surface of Mars. On the image displayed on the screen in the flight control center a few minutes after landing, small particles of Martian dust are visible.

Two 737 passenger flights landed at Darwin Airport in September 2021 with unnecessarily reduced landing distances available to them after their flight crews misinterpreted NOTAMs detailing that a displaced threshold was in place due to runway works.
The incidents occurred on two flights operated by Virgin Australia Boeing 737-800s: the first on 3 September 2021, from Melbourne to Darwin, the second on 19 September 2021, from Brisbane to Darwin.
On both occasions, during pre-flight briefings, flight crews misinterpreted a NOTAM (notice to airmen) for Darwin Airport. The NOTAM stated that runway 29 (for landing from the east) had a displaced threshold of 765 metres due to works in progress and that the eastern end of the runway was not available due to the works.
Landing from the west on runway 11, however, did not require using the displaced threshold, although the landing distance available, due to the runway works at the eastern end, was reduced to 2,670 metres.
“On both occasions, the flight crews misinterpreted the NOTAM and conducted unnecessary displaced threshold landings, reducing the available runway for their landings.”
Both aircraft landed without incident.
“These incidents highlight the critical importance that operational information in a NOTAM can have for the planning and conduct of a flight,” ATSB Director Transport Safety Stuart Macleod said.
“Misinterpretation of NOTAM information can significantly affect flight safety.”
In addition, Mr Macleod noted correct and complete readback of air traffic control clearances are important to confirm information has been received and understood.
“Readbacks provide a valuable defence to detect and correct errors such as occurred during these incidents,” he said.
“Flight crews are also encouraged to seek clarification from air traffic control when there is uncertainty or ambiguity about the condition of a destination, such as a displaced threshold.”
After the first incident, Virgin Australia updated their Flight Crew Operational Notice for Darwin Airport. It then modified it further after the second incident, to specifically highlight the displaced thresholds. | Yes |
"We are examining the issue. Air India management has sent a report to the (Civil Aviation) Ministry. They have acted as per the operations manual," DGCA chief Arun Mishra told PTI.
Airline sources said both the pilots have been suspended and taken off the roster, pending an internal inquiry.
The Directorate General of Civil Aviation (DGCA) is conducting a thorough probe into the "flagrant violation of passenger safety norms," a senior official said.
The pilots, Jagan M Reddy and S Kiran, had allowed 25-year-old Kannada actress Nithya Menon to enter the cockpit mid-air and sit through the flight duration, according to a complaint lodged by a passenger.
The passenger said the actress had during the hour-long flight occupied the observer's seat, which is reserved for examiners and observers authorised by DGCA.
With quite a few such incidents coming to fore in the past months, the regulator is considering imposing harsher penalties on the cockpit crew, the sources said, adding that cockpit entry by a passenger is completely prohibited since the 9/11 terror strike.
In May, the pilot of an Air India flight from Delhi to Bangalore got locked out of the cockpit as the door got jammed, resulting in the co-pilot making an emergency landing in Bhopal.
In April, two stewardesses were inside the cockpit for nearly 45 minutes as one of the two pilots had taken a long break.
Who is Nithya Menon?
Menon, a Malayali born in Bangalore, is a journalism graduate from Manipal.
She, however, changed tack and enrolled for FTII Pune to become a director, there she is said to have been convinced to take up acting.
Nithya Menon appeared first as a child actor in The Monkey Who Knew Too Much in 1998.
Her debut as an actor was in the Mohanlal-starrer Aakasha Gopuram ten years later. She then acted in Kannada films. She has also acted in several Telugu and Tamil films.

“This revised timeline for first delivery accommodates the work we believe remains to be done to complete testing and certification of the 787,” said Scott Fancher, vice president and general manager of the 787 program. “We’ve also restored some margin in the schedule to allow for any additional time that may be needed to complete certification activities,” Fancher said.
The 787 program has been gradually returning individual airplanes to the flight test program. After receiving interim software and hardware improvements, four flight test airplanes have been subjected to extensive ground testing and a thorough review to ensure their readiness to return to flight. The remaining two airplanes will be returning to flight in the days ahead to bring the full flight test fleet back up to flight status.
News agencies are reporting that Iranian authorities will ban flights of Russian-made Tupolev Tu-154 aircraft from February 20.
“All Iranian airline companies which have Tupolev-154 in their fleet are required to end operation of their Tupolevs by February 19,” the country’s civil aviation chief told media.
Four Iranian air carriers – Iran Air Tour, Kish Air, Eram and Taban – who have a total of 17 Tu-154 jets in their fleets, were instructed to ground their Tupolevs by February 19 and replace them with other planes. Which planes that might be is unclear.
“The use of Tu-154 planes is banned in connection with recent incidents involving those aircraft,” the civil aviation chief said in his letter to the air carriers.
Iranian authorities criticized the Russian Tupolev manufacturer for refusing to respond to the Iranian Civil Aviation Organization’s request in connection with recent Tu-154 accidents.
Over the last 10 years, 5 Tupolev Tu-154 crashed in Iran, killing more than 300 people.
In an effort to renew its outdated civil aviation fleet, Iran plans to import 13 McDonnell Douglas MD-80 and 6 Airbus planes in the near future. The Islamic Republic will also start the domestic production of the IrAn-140 passenger plane, that is based on the Antonov An-140.
Iran is treated by international sanctions (UN and US) which, at some level, prohibit import of modern airplanes, spare parts and any other “aviation related material”.
The Chengdu J-20, first Chinese 5th generation stealth fighter, today successfully completed its first flight! According to Chineses sources the jet fighter made a 15-minute flight in southwest China’s City of Chengdu.
The Chengdu J-20 is a twin-engine multi-role heavy fighter with stealth capability and maneuverability as compared to American F-22 Raptor and Russian Sukhoi T-50 PAK FA.
An Iran Air Boeing 727-286 (EP-IRP) crashed yesterday evening near Urmia (Orumiyeh) Airport (OMH), Iran, killing at least 77 souls on-board.
Flight IR277 was bound from Tehran-Mehrabad Airport (THR) to Urmia. The 36 year old plane crashed during an emergency landing in heavy snow storm after the pilots reported technical problems.
Ongoing international sanctions on the country are blamed for the recent history of deadly aviation accidents. United Nations Security Council Resolution 1929 still prohibits international supply of aircraft, strongly needed aircraft parts as well as “related material” to Iran.
Aviation Week is reporting that Chinese aviation enthusiasts have spotted a mysterious jet fighter at Chengdu Airport, China. It’s believed that the plane might be the infamous J-20 – the first Chinese stealth fighter, built by Chengdu Aircraft Industry Corporation (CAC).
Judging from the pictures you can’t deny big similarities to an F-22 and the Sukhoi T-50 PAK FA. It seems to be much larger than an F-22 though.
The Chengdu J-20 was first disclosed by US Office of Naval Intellegence (ONI) in 1997 as XXJ, J-20 (?) and is a 5th generation fighter to enter service around 2015. The jet is believed to be a twin-engine multi-role heavy fighter with enhanced stealth capability and maneuverability comparable to American F-22. It was speculated that 601 Institute was working on a “tri-plane” design based on canard/conventional layout/V-shape tailfin while 611 Institute working on a design based on canard/tailless delta wing/all moving V-shape tailfin/side DSI/bump inlet layout. All designs were expected to feature an internal weapon bay to reduce its radar footprint. The overall performance of J-20 is thought to be superior to Russian T-50 but still inferior to Amereican F-22. In August 2008 it was reported that 611 Institute was selected to be the main contractor for the development of J-20 and 601 Institute as the sub-contractor. One rumor in May 2010 suggested that 611 Institute started to construct the first prototype, which is expected to fly by 2012. The latest rumor claimed that the first two prototypes have been constructed and the first high-speed taxiing trial took place on December 22, 2010.
I’m absolutely fascinated about this video. In 2009 James May, presenter of UK TV series “Top Gear”, took a ride in a USAF Lockheed U-2 (TU-2S two-seat trainer) – they reached an altitude of 70000 feet. If you’re an aviation buff (and I know you are) you definitly have to watch this.
On Friday US Air Force released the results of their investigation into a fatal C-17 Globemaster III aircraft (tail number 00-0173 – call sign Sitka 43) mishap July 28 at Joint Base Elmendorf-Richardson, Alaska.
The plane was on a training flight for the Arctic Thunder Air Show scheduled for the weekend of July 31.
The accident investigation board found clear and convincing evidence the cause of the mishap was pilot error. The investigation revealed the pilot placed the aircraft outside established flight parameters and capabilities. During the mishap sortie, the pilot aggressively flew the aircraft in a manner inconsistent with established flight procedures, resulting in a stall. The pilot failed to take required stall recovery actions.
Furthermore, the board concluded the co-pilot and safety observer failed to recognize or address the developing dangerous situation. As a result, the C-17 stalled at an attitude and altitude from which recovery to controlled flight was impossible.
Video footage of the mishap flight was officially released and is found on YouTube. The footage has been edited to cut off just prior to the aircraft’s impact out of consideration and respect for the families of the deceased.
What about some airshow fun on this cold December day? 😉 I just found this amazing video on YouTube, showing Rob Holland in his MX2 at Daytona Wings and Waves Airshow 2010. The footage is taken straight out of the cockpit using a helmet camera! So you’re going to see the whole action from pilots eye in finest HD quality!

Today a preliminary report on Qantas flight QF32 (Airbus A380 VH-OQA) was released by Australian Aviation Safety Bureau (ATSB). On 4 November the flight sustained an uncontained failure of the Intermediate Pressure (IP) turbine disc on engine No 2.
The report reveals many interesting details about sustained damage, flight crew response, a brief history of the flight, cause of the incident and data obtained from flight data recorder (FDR). (link at the bottom)
Following a short summary of events that occured on-board
The crew reported that, while maintaining 250 kts in the climb and passing 7,000 ft above mean sea level (AMSL), they heard two, almost coincident ‘loud bangs’.
The crew reported a slight yaw and that the aircraft immediately levelled off in accordance with the selection of altitude hold
PIC noticed that the autothrust system was no longer active
Electronic Centralised Aircraft Monitor (ECAM) system displayed a message indicating an “overheat” warning in the No 2 engine turbine. Soon after, multiple ECAM messages started to be displayed. The PIC confirmed with the flight crew that he was maintaining control of the aircraft and called for the commencement of the requisite ECAM actions by the FO in response to those messages.
Affected engine’s thrust lever was moved to IDLE and a PAN radio call was transmitted to Changi air traffic control (ATC)
Warning indicating a fire in the No 2 engine that displayed for about 1 to 2 seconds; the ECAM then reverted back to the overheat warning
The crew decided to shut down No 2 engine; after they had selected the ENG 2 master switch OFF, the ECAM displayed a message indicating that the No 2 engine had failed
The crew reported assessing that there was serious damage and discharged one of the engine’s two fire extinguisher bottles into the engine
Flight crew did not receive confirmation that the fire extinguisher bottle had discharged. They repeated the procedure for discharging the fire extinguisher and again did not receive confirmation that it had discharged.
Crew followed the procedure for discharging the second fire extinguisher bottle into the No 2 engine. After completing that procedure twice, they did not receive confirmation that the second bottle had discharged.
Continuation with engine failure procedure, which included initiating an automated process of fuel transfer from the aircraft’s outer wing tanks to the inner tanks.
Engine display for the No 2 engine had changed to a failed mode
Engine display for Nos 1 and 4 engines had reverted to a degraded mode (indicates that some air data or engine parameters are not available)
Display for No 3 engine indicated that the engine was operating in an alternate mode as a result of actioning an ECAM procedure
Crew recalls following systems warnings on ECAM after failure of engine No 2:
Engines No 1 and 4 operating in a degraded mode
GREEN hydraulic system – low system pressure and low fluid level (one of two primary hydraulic systems – power is supplied by engine-driven pumps on Nos 1 and 2 engines)
YELLOW hydraulic system – engine No 4 pump errors (second of two primary hydraulic systems – power is supplied by engine-driven pumps on Nos 3 and 4 engines)
Failure of the alternating current (AC) electrical No 1 and 2 bus systems
Flight controls operating in alternate law (reduces some of the flight control protections that are available under normal law)
Wing slats inoperative
Flight controls – ailerons partial control only
Flight controls – reduced spoiler control
Landing gear control and indicator warnings
Multiple brake system messages
Engine anti-ice and air data sensor messages
Multiple fuel system messages, including a fuel jettison fault
Centre of gravity messages
Autothrust and autoland inoperative
No 1 engine generator drive disconnected
Left wing pneumatic bleed leaks
Avionics system overheat
Photo: Damage to electrical wiring located in the leading edge of the left wing (punctured by debris)
Customer service manager (CSM) attempted to contact the flight crew, including through use of the EMERGENCY contact selection on the cabin interphone system. This activated the flight deck warning horn. No associated ECAM message was displayed, the flight crew associated the emergency contact warning horn with the continuously-sounding warnings from the ECAM system and cancelled the horn.
holding at the present altitude while processing ECAM messages and associated procedures – no immediate return to Singapore – needed holding pattern for about 30 minutes
20 NM (37 km) racetrack holding pattern at 7,400 ft east of Singapore
ATC acknowledged crew that a number of aircraft components found on Indonesian island of Batam
Second Officer (SO) was dispatched into the cabin to visually assess the damage to the No 2 engine; a passenger, who was also a pilot for the operator, brought the SO’s attention to a view of the aircraft from the vertical fin-mounted camera that was displayed on the aircraft’s in-flight entertainment system. That display appeared to show some form of fluid leak from the left wing.
Photo: Left wing fuel tank damage (punctured by debris)
SO proceeded to lower deck on the left side of the aircraft to observe damage to the left wing and fuel leaking. The fluid leak appeared to be coming from underneath the left wing, in the vicinity of the No 2 engine and that the fluid trail was about 0.5 m wide. The SO could not see the turbine area of the No 2 engine from any location within the cabin.
Elected not to initiate further fuel transfer – were unsure of the integrity of the fuel system. Could not jettison fuel due to ECAM fuel jettison fault
Noticed that the aircraft’s satellite communications system had failed and received ACARS message from aircraft operator that indicated that multiple failure messages had been received from the aircraft
SCC and PIC made a number of public address (PA) announcements to the passengers indicating that the aircraft had sustained a technical failure, and that the crew were addressing the issues associated with that failure. Subsequently, the SCC and SO returned to the cabin on numerous occasions to visually assess the damage on the left side of the aircraft, and to inspect the right side of the aircraft, and to provide feedback to the cabin crew and passengers.
It took about 50 minutes to complete all initial procedures associated with ECAM messages. During that time, the autopilot was engaged.
They assessed the aircraft systems to determine those that had been damaged, or that were operating in a degraded mode. They considered that the status of each system had the potential to affect the calculation of the required parameters for the approach and landing. The crew also believed that the failure may have damaged the No 1 engine, and they discussed a number of concerns in relation to the lateral and longitudinal fuel imbalances that had been indicated by the ECAM.
Input of affected aircraft systems into landing distance performance application (LDPA) to determine the landing distance required for an overweight landing to runway 20C at Changi Airport of about 440 t, which was 50 t above the aircraft’s maximum landing weight.
Based on the initial inputs to the LDPA by the flight crew, the LDPA did not calculate a landing distance. After discussion, and in the knowledge that the runway at Changi was dry, the crew elected to remove the inputs applicable to a landing on a wet runway and re-ran the calculation. This second calculation indicated that a landing on runway 20C was feasible, with 100 m of runway remaining. The crew elected to proceed on the basis of that calculation and advised ATC to that effect.
Crew advised ATC that they would require emergency services to meet the aircraft at the upwind end of the runway, and that the aircraft was leaking fluid from the left wing that was likely to include hydraulic fluid and fuel.
Crew discussed the controllability of the aircraft and conducted a number of manual handling checks at the holding speed. The crew decided that the aircraft remained controllable
Lowering of flaps – remained controllable
As result of the landing gear-related ECAM messages, the landing gear was lowered using the emergency extension procedure and a further controllability check was conducted
Crew was aware of: reverse thrust was only available from the No 3 engine, no leading edge slats were available, there was limited aileron and spoiler control, anti-skid braking was restricted to the body landing gear only, there was limited nosewheel steering and that the nose was likely to pitch up on touchdown. An ECAM message indicated that they could not apply maximum braking until the nosewheel was on the runway.
The wing flaps were extended to the No 3 position
The PIC was aware that accurate speed control on final would be important to avoid either an stall condition, or a runway overrun. Consequently, the PIC set the thrust levers for Nos 1 and 4 engines to provide symmetric thrust, and controlled the aircraft’s speed with the thrust from No 3 engine.
Autopilot disconnected a couple of times during early part of approach as the speed reduced to 1 kt below approach speed. The PIC initially acted to reconnect the autopilot but, when it disconnected again at about 1,000 ft, he elected to leave it disconnected and to fly the aircraft manually for the remainder of the approach. Due to the limited landing margin available, the CC reminded the PIC that the landing would have to be conducted with no flare and that there would be a slightly higher nose attitude on touchdown.
Cabin crew was briefed to prepare for a possible runway overrun and evacuation
Aircraft touched down, the nosewheel touched down within about 6 seconds, the PIC commenced maximum braking and selected reverse thrust on No 3 engine. The flight crew observed that the deceleration appeared to be ‘slow’ in the initial landing roll, but that with maximum braking and reverse thrust, the aircraft began to slow. The PIC recalled feeling confident that, as the speed approached 60 kts, the aircraft would be able to stop in the remaining runway distance. In consequence, the No 3 engine was gradually moved out of maximum reverse thrust. Manual braking was continued and the aircraft came to a stop about 150 m from the end of the runway. The aircraft was met by emergency services.
After landing, crew commenced to shut down the remaining engines. When the final engine master switch was selected OFF, the aircraft’s electrical system went into a configuration similar to the emergency electrical power mode. That rendered many of the aircraft’s cockpit displays inoperative, and meant that there was only one very high frequency (VHF) radio available to the crew.
Just before the cockpit displays went blank, a number of the flight crew noticed that the left body landing gear brake temperature was indicating 900 °C, and rising. After some initial confusion about which radio was functioning, the FO contacted the emergency services fire commander, who asked for the No 1 engine to be shut down. The FO responded that they had done so already, but was advised again by the fire commander that the engine continued to run.
recycled the engine master switch to OFF but the engine did not shut down
use of emergency shutoff and fire extinguisher bottles but the engine did not shut down
tried to activate a series of circuit breakers in the aircraft’s equipment bay, the engine did still not shut down
attempts were made to reconfigure the transfer valves in the aircraft’s external refuelling panel, in an effort to transfer fuel out of the No 1 feed tank, and starve the No 1 engine of fuel. However, due to the lack of electrical power, that was not possible.
Ground engineers attended the aircraft and attempted a number of methods to shut down the engine, each without success
Finally, the decision was taken to drown the engine with fire-fighting foam from the emergency services fire vehicles. The No 1 engine was reported to have finally been shut down about 2 hours and 7 minutes after the aircraft landed.
Fire commander indicated that there appeared to be fuel leaking from the aircraft’s left wing. The FO advised the commander of the hot brakes, and requested that fire retardant foam be applied over that fuel. The fire commander complied with that request
four of the wheels on the left body landing gear had deflated
55 minutes after landing – after the fire risk had decreased – passengers disembarked via stairs on the right side of the aircraft, using only a single door (No 2 main deck forward door), to keep remaining doors clear in case of the need to deploy the escape slides. | Yes |
The telescope is a marvelous instrument. Its lenses and mirrors perform magic by bringing what's distant closer.
It's also a marvelous metaphor for this time of year, as we look to the future and wonder what it will look like when it becomes our present.
This year, the metaphorical and the actual aligned for everyone navigating the road ahead, when the James Webb Space Telescope finally launched. Sure, its production went over budget by billions, and yes, it lifted off 11 years later than first anticipated, frequent consequences of pursuing audacious goals.
But all of that delivered a launch on Christmas Day, adding to the annual font of anticipation. Where many among us traditionally lift our eyes to the heavens figuratively, this time we did so in reality.
The Webb blasted off from a tropical rainforest in French Guiana, on the northern coast of South America. Its earliest moments of flight were obscured by clouds, not unlike our own muddled present. And as it passed in and out of view as it climbed, it was easy to see those moments of uncertainty as representing the mysteries the telescope was designed to solve.
Its mission is ambitious — to look back more than 13 billion years at the first stars and galaxies that emerged after the Big Bang, and to hunt for clues about the formation of black holes. This is origin-of-life stuff. The Webb also will be seeking the infrared signatures of oxygen and water on planets orbiting distant stars. That's life-elsewhere-in-the-universe stuff.
And it will be doing so from its eventual perch 1 million miles from Earth.
Its numbers are the kind that are difficult to wrap your mind around. But they're also the kind of numbers that inspire.
The Webb's ultimate payoff lies in providing the information astronomers and physicists need to deepen their accounts of cosmic history. The telescope's more immediate benefit is what it teaches us about ourselves.
The Webb demands we look up rather than down and consider the endless expanses of space and time rather than the confines of our daily lives. It is a celebration of human ingenuity and technical achievement, a testament to the power of dreams and imagination. It is proof that yearning and grasping can find fruit, and it shows us for the magnificent strivers that we are.
Of course, high rewards don't come without high risks and this mission has plenty, from the journey itself to the many maneuvers that must be made remotely for the telescope to become operational — like the ongoing "unfolding" of a tennis-court-sized sunshield to protect the telescope from intense solar radiation. It's only one of what NASA says are 344 potential single-point failures, not unlike what seems to be 344 anxieties we contend with every day right now.
The Webb will have plenty of celestial company in inspiring us in 2022. The space agencies of Europe and Russia will team to send a rover to Mars, scheduled for September, when it will join rovers from the United States and China already on the Red Planet's surface. NASA's DART mission is slated to slam into an asteroid in 2022 to see whether that could be a way to divert a future one headed for Earth. Another NASA mission intends to explore a strange, metal-rich asteroid that might be part of the core of an early planet. And the U.S., Russia, India, and Japan will send missions to and around the Moon.
The Webb itself is a grand partnership between NASA, the European Space Agency and the Canadian Space Agency, and its instruments and data will be used by scientists around the world from all sorts of countries.
More reasons for hope, in a fractious world, at any time of year.

The advent of the space era signalled a great boost for all geosciences, since scientific observational methods were not limited any more to terrestrial only, but to satellite ones as well. Considering the main advantages of satellite methods we can immediately distinguish their improved observational methods, the dense coverage as well as the repeatability and homogeneity of the data offered for almost the entire planet. The Earth’s oceans cover almost 73% of our planet’s surface, thus the interactions that take place on their surface and interior trigger and direct changes in the environment and the natural and human ecosystem. One of the main goals of space geodetic techniques and of satellite altimetry in particular is the study and observation of the processes and properties of the marine environment, so that when utilizing altimetry data monitoring and studying of phenomena like mean sea level variations and changes, ocean circulation, mass variations and balance, ice transfer, wind speed, storm surges, wave height and water temperature would be feasible. It is easily concluded that coastal zone monitoring and management can be greatly benefited by utilizing the measurement provided by satellite altimetry, since the late offer direct observations of the sea level and of its variations. Altimetric measurements have a vital importance for geosciences, since we are lucky enough to have satellites that provide very accurate and direct measurements of the instantaneous heights of the sea. This is so, since the altimetric observables, the sea surface heights (SSHs), correspond to the separation of the sea surface from the reference ellipsoid and are very close to geoid undulations. Once having these measurements and with proper handling through appropriate procedures one can derive the deviations of the geoid above the ellipsoid and therefore determine a reference equipotential surface useful to geodetic, oceanographic, geological, geodynamic and hydrological studies. The data offered to the scientific community come from different agencies such as the French Archiving, Validation and Interpretation of Satellite Oceanographic data (AVISO), the Centre ERS d’Archivage et de Traitement (CERSAT), the Centrale Nationale d’ Etudes Speciales (CNES), the Collect, Localization, Satellites (CLS) project at the University of Texas, the European Space Agency (ESA), the Jet Propulsion Laboratory (JPL) through its Pathfinder project, the National Aeronautics and Space Administration (NASA) and finally the National Oceanic and Atmospheric Administration (NOAA).
Altimetric satellites and missions
In the following paragraphs we will briefly give some introductory information about the already launched and expected altimetric satellites, together with their characteristics and missions.
Skylab, GEOS-3 and Seasat
The beginning of satellite altimetry, as it was defined in the introductory chapter, originates in the first purely altimetric satellite GEOS-3, which was launched in 1973. Before GEOS-3 there have been a number of satellites with the name Skylab, which conducted some experimental altimetric measurements without this being their primary goal. The Skylab satellites where the first ones to perform altimetric observations and they formed the basis for the first complete altimetry mission with SEASAT.
The next satellite launched was the GEOdetic SATellite (GEOSAT), which is considered as the cornerstone of satellite geodesy and satellite oceanography. The satellite’s name, GEOSAT (see Figure 1), indicates its primary mission, i.e., the approximation of the oceanic geoid. GEOSAT was constructed at the Applied Geophysics Laboratory of Johns Hopkins University under the supervision of the U.S. Navy. The satellite was equipped with one altimeter, which measured the distance between the satellite and the instantaneous sea surface (ISS) as well as the wave height and the wind speed.
The European Earth Remote-sensing Satellite 1 (ERS1) followed GEOSAT’s mission on July 17, 1991 and was launched by the European Space Agency (ESA) (see Figure 2). The primary goal of ERS1 was to study the oceans, monitor the ice sheet movements, measure the wave height and the ocean surface temperature and determine the wind speed and direction. These are only the altimetric tasks that ERS1 was dedicated to do, since the satellite carried a multitude of scientific instruments for many other different types of experiments. ERS1 was originally scheduled to fly for two years only, but since the altimeter recorder was continuing to operate and the satellite was in good health, its mission continued until 1996 when it was used in a tandem phase for the calibration of its successor ERS2.
TOPEX/POSEIDON, JASON-1 and JASON-2
The altimetric mission of JASON-1 (Figure 4) was launched in December 7, 2001 and constitutes the continuation of T/P. The satellite is the result of cooperation between NASA, through its Jet Propulsion Laboratory (JPL), CNES, through AVISO (Archiving, Validation and Interpretation of Satellite Orbit) and CLS (Collect, Localization, Satellites). JASON-1 was the first satellite in a row planned to launch in the next 20 years, all aiming to provide a continuous record of the variability and the state of the Earth’s oceans. JASON-1 is revolving the Earth at an altitude of 1336 km with a 66ο inclination and a period of 112 min. It has already completed 240 complete cycles around the Earth and repeats its orbit track with a horizontal accuracy better than 1 km at the equator. It successor, JASON-2 has been launched in June 20, 2008 and its main goals are to monitor ocean tides, mean sea level change, as well as the ocean circulation and sea level variability in scales longer than ten years, which will result by the combination of its data with those of T/P and JASON-1.
GFO altimetric satellite
After the great success of the altimetric mission of GEOSAT, which is considered as one of the most successful satellites for military and geodetic applications, the U.S. Navy decided to launch its successor called Geosat Follow On (GFO) in February 10, 1998. The satellite repeats the 17.05-day GEOSAT ERM mission, thus providing observations at the exact same tracks as its predecessor did almost 15-years ago.
ENVISAT (ENVIronmental SATellite) is the successor of ERS1/2 and was launched in March 1, 2002 by the European Space Agency (ESA). The satellite is set in a polar sun-synchronous orbit with an inclination of 98.55o and its life span is scheduled to ten years. It should be noted that ENVISAT is not a purely altimetric satellite, but has a wide variety of instruments in order to monitor many natural processes that take place on the Earth’s surface (monitoring of the atmosphere, the oceans, polar as well as continental areas). So, altimetric measurements are just a component of the entire laboratory aiming to continue the successful record of the ERS1/2 missions.
Satellite altimetry principle
The definition of some basic terms related to satellite altimetry is presented in Figure 6 which depicts a basic altimetric system. As range we define the distance from the satellite centre of mass to the instantaneous sea surface. This is the main measurement that the altimeter provides. As satellite altitude we define the distance between the satellite centre of mass and the reference ellipsoid in the direction of the normal to the ellipsoid. As height or sea surface height (SSH) we define the deviation of the instantaneous sea surface from the reference ellipsoid. This is given as the difference between the altitude and the range. As orbit we define the path that the satellite follows while revolving around the Earth. As revolution we define a complete revolution of the satellite around the Earth. As satellite pass we define the half of a satellite revolution. The satellite passes are distinguished in ascending and descending ones. Ascending passes are those that the satellite goes from South to North (North-going passes) and descending those that the satellite goes from North to South (South-going passes). Finally, as a complete satellite repeat cycle we define the time period until the satellite passes twice from the exact same point. It is obvious that this term is found in ERM phases only.
The principle of satellite altimetry (see Figures 6 and 7) is based on the transmission of a radar pulse from the altimeter towards the surface of the Earth along the vertical and its subsequent reflection from the sea surface towards the satellite receiver. The satellite has an accurate on-board time-tagging device, which measures the time needed for the radar pulse to do this two-way trip from the satellite to the sea surface and then back to the satellite receiver. After proper processing and the removal of instrumental and geophysical corrections the distance between the satellite and the ISS is computed, which is called range or instantaneous sea surface topography (ISST). This is computed as half the time that the radar pulse needed to travel from the satellite two the sea surface and then back to the satellite. The distance between the ISS and the mean sea surface (MSS) is called time-varying sea surface topography (TSST) and is denote by ς_t in Figure 7. It is caused by many factors like the earth tides, the ocean currents and meteorological phenomena. For some of these parameters available models have been developed either in a global, regional or local scale. Finally, the distance between the geoid and the MSS is called quasi-stationary sea surface topography (QSST), denoted by ς_c in Figure 7, and originates from various dynamic phenomena in the oceans such as the temperature, the salinity and the dissolved oxygen content. Additionally, it is attributed to the loading of the oceans due to the existence of ocean currents.
Measuring and monitoring coastal zones of a changing planet from space
The main products of satellite altimetry techniques useful in monitoring and managing coastal areas refer to models of the mean sea surface, of the bathymetry and of the sea circulation. Mean sea surface (MSS) models are generated by integrating sea surface height measurements from multi-satellite missions, so as to achieve wide-coverage, high-accuracy and high-resolution. In Figure 8 an example of a multi-mission combination setup is presented for the Eastern Mediterranean and Black Seas, where TOPEX/Poseidon (T/P) and ERS1/2 data have been combined for the determination of a MSS model. After various combination schemes have been examined, a model based on Least Squares Collocation has been determined with a spatial resolution of 2 arcmin, in both latitude and longitude, and an accuracy in the order of 4-5 cm (standard deviation – std). The result from this multi-mission combination for MSS determination is presented in Figure 9. Apart from a picture of the mean state of the sea, such models offer a great opportunity to perform studies on the variations of the sea level at least in time-scales that the altimetric data record allow. In the same study (Tziavos et al. 2004), sea level variations relative to the determined MSS model for the period 1993-2001 have been determined for the Aegean Sea. From the results acquired it was determined that a regular seasonal pattern was evident while a significant response to ENSO events like El Niño and La Niña could be spotted in the analysis performed. These variations are depicted in Figure 10, where the seasonal pattern is evident.
Another opportunity to monitor the sea surface and collect data closer to the coastline where space methods suffer due to the scattering of the radar pulse by the ocean bottom is the so-called marine GPS-measurements. The entire concept is based on the development of enhanced ground-based methods for the precise determination of Sea Surface Heights (SSH), through a system consisting by shipborne multi-antenna GPS measurements (Figure 12) and GPS equipped buoys (Figure 11). The SSH data provide local-scale information on the short-wave structure of the gravity field and can be used to improve local marine geoid solutions, monitor the sea variability especially close to the coastline and determine ocean circulation. They also contain information on the local dynamic ocean topography (DOT) and can be used for the validation and calibration of radar altimeter satellites. In addition, they can provide a link between offshore radar altimeter data and tide-gauge stations.
Highly-precise GPS positioning of the buoys and the boat is achieved by simultaneously operating the buoy receivers, the receivers aboard the boat and several permanent terrestrial GPS reference stations, all operated at a sampling rate of 1 Hz. The coordinates of the reference stations are first determined with respect to the ITRF reference frame. The kinematic positions of the buoys and the boat are then determined through differential GPS carrier phase processing with respect to the reference stations. In order to derive the Sea Surface Topography (SST) from the instantaneous SSHs, several corrections have to be applied, especially for tides and atmospheric effects (inverse barometer effect). The tide corrections can be computed using any global tide model, e.g., the GOT00.2 model, while local tidal effects can be determined by using tide gauges installed in the survey area. The inverse barometer corrections can be computed using ECMWF atmospheric pressure data. Such a study has been performed in the Aegean Sea in 2004 and 2005, totalling more than 1000 nm (nautical miles) of ship tracks (Fig. 13). For calibration and validation purposes of radar altimeter missions, the survey area has been chosen in the vicinity of Jason-1 ground-tracks. Dedicated buoy measurements have been performed along these Jason-1 tracks, including deployments with direct Jason-1 crossovers, which provide precise ground-truth SSH information during the overflight. From the description of the method it is evident that measurements can be performed as close to the coastline as one wishes, with the only limitation being the depth of the sea and the height of the sailing boat keel. Of course in case a sail boat’s tender is used, then this depth limit reduces to lets say 20 cm, which practically means that the system is capable of performing measurements in virtually all coastal areas.
A direct consequence of the continuous development of MSS models of the ocean is that they are usually combined with satellite-only Earth Gravity Models (EGMs) to estimate models of the Quasi-Stationary Sea Surface Topography (QSST). The QSST is defined as the semi-constant over large periods of time deviation of the mean sea surface from the geoid. It reaches a maximum of +2.2 m and in closed sea areas has very small variations over large regions. This is why most QSST models developed during the last two decades are usually provided in terms of a spherical harmonics expansion of the QSST to low degrees, e.g., 20 (which corresponds to about 2000 km full wavelength). It can be easily concluded that when the area under study is rather small or is characterised as closed, e.g., the Mediterranean Sea, then such global models are insufficient. Moreover, in areas like the aforementioned the differences between the presently available global QSST models largely exceed the magnitude of the signal under consideration itself. This signals both a significant uncertainty in the available models and a need for the development of reliable and accurate local estimates of the QSST for use in geodetic and oceanographic studies.
The QSST is needed in geodetic and oceanographic studies for the reduction of the altimetric measurements from the sea surface to the geoid. This is so because the basic measurements of satellite altimeters, the sea surface heights (SSHs), refer to the sea surface and not the geoid itself. Therefore, the reduction of these observations to the geoid is necessary to determine a geoid and not a MSS model. Additionally, shipborne gravity measurements refer to the sea surface as well and need to be free-air reduced to the geoid to be used for the determination of a gravimetric geoid. The quantity needed for this reduction is the QSST, which is the “marine” counterpart of orthometric heights on land. It can be easily concluded that the QSST is significant for the precise and accurate determination of gravity-field related quantities, while local models are highly necessary as well to serve local to regional geoid modelling. Moreover, since the geoid serves as the reference surface for oceanographic measurements, its determination and separation from the MSS is necessary as well. Finally, under the assumption of geostrophic flow, the QSST can be used to determine the direction and magnitude of the ocean currents, with obvious implications to coastal zone management and monitoring since the circulation of the sea has a direct effect in coastal erosion, habitat changes and determines the biodiversity of coastal regions. An example of a QSST model is presented in Figure 14 for the Southern Aegean Sea (Vergos 2006, Vergos and Tziavos 2007), while Figure 15 presents the resulting circulation in the area. From Figure 15 we can clearly distinguish some well-known jets in the area like the Mid-Ionian (MIJ) and Mid-Mediterranean ones (Mid-MED Jet), the Western Cretan Gyre (WCG), the Ierapetra Anticyclone (IAC), Rhodes Gyre (RG) and the Cyclades Anticyclone (CAC). Furthermore, South of the island of Crete we can identify a small (in terms of magnitude) jet (dotted lines), which can be either a branch of the Mid-Mediterranean one or a jet by its own. Finally, there is a clear flow from the Aegean Sea (jets J1 and J2) which merge into the Western Cretan Anticyclone and probable “feed” the MIJ.

For those who are eagerly waiting to watch Moscow’s air show, this show has a lot to see. The makers of Russian aircraft unveil that they will present an anticipated new fighter jet on this show which will be conducted next week. This new jetliner has hidden inside the tarpaulin was captured being towed to a spot of parking across an airfield which is in Zhukovsky outside of Moscow where the MAKS2021 International Space and Aviation Salon open on Tuesday. The President of Russia, Vladimir Putin is all ready to visit the Air show for the opening.
Russian Fighter Jets
As per the reports of Russian Media, the new jet has been constructed by the maker of Sukhoi aircraft during a program of development of the light tactical fighter. Different from Russia’s latest Su-57, 2 engine stealth fighter, the new aerodyne is smaller and only has one engine in it. The aircraft Su-57 has been constructed to match the level of U.S. F-22 Raptor stealth fighter but is different from American aerodyne that has been working and giving service since 2005.
The serial production is just beginning and a new engine deliberate to give it the capability to sail at jetliner speed which is still under development. The name of this new warplane is still not revealed yet and no such information is available regarding this warplane including its capability and stationing prospects. The anticipated Russian fighter plane appears deliberated to fight with the U.S. F-35 Lightning II fighter, and this fighter plane started its service in the year 2015.
Russian government hoping to provide or offer the new aerodyne to overseas customers. The Russian makers made a statement that “fundamentally new military aircraft” will be introduced on Tuesday, 20th July 2021 at the Air show of Moscow. The statement further added, “Russia is one of some countries in the globe with full-cycle capability for developing advanced aerodyne systems, as well as an acknowledged trendsetter in the development or the creation of combat aerodyne.”
In order to increase the interest of the out lookers before the presentation, Rostec introduced a photograph of the new aircraft which is hidden under the tarpaulin along with the caption “Wanna see me naked?” A small video clip is also posted in order to create a sensation amongst the overseas customers and the aircraft’s ambiguous shadow on top of the water. | Yes |

Random Thought From Childhood:
Moon Covered in Snow
When I was a kid, I thought the moon was covered in snow. The moon is white;snow is white. It made perfect sense to me. Further, I thought the moon was a fun place to visit since it was covered in snow. After all, during snow-days in grade school, I always had a good time. The moon looked like a big playground.
Fortunately, I kept this strange thought to myself. And I was able to figure out quickly that the moon was not covered with snow, or at least on the light-side. On the light-side, the moon is well over the boiling point of water. So, I was able to figure out that the whiteness I saw on the moon was not snow.
But I wasn't totally let down. I was still intrigued by the moon because gravity there is 1/6th what it is on Earth. I thought since people would be so light on the moon, jumping on the moon would be like jumping on a trampoline. | Yes |

The last men on the moon: Nasa releases 1972 shot of Apollo 17's crew exploring lunar valleys in search of rocks
The 1972 Apollo mission 17 brought back 110 kilos of moon rock - but it's more famous as the last mission where astronauts walked on the moon.
Nasa released the image via its Astronomy Picture of the Day website - 40 years after the astronauts harvested 100 kilos of moon rock, by far the biggest haul of any mission.
In December of 1972, Apollo 17 astronauts Eugene Cernan and Harrison Schmitt spent about 75 hours on the Moon in the Taurus-Littrow valley, while colleague Ronald Evans orbited overhead.

The three astronauts (from left to right - Eugene Cernan, Ronald Evans and Harrison Schmitt) get the red-carpet welcome back as they splashdown on December 19, 1972
Apollo 17 was the sixth and last Apollo mission and the last time that humans walked on the surface.
The mission returned to earth on December 19, 1972.
The team carried out a series of experiments including seismic profiling, atmospheric composition analysis and lunar sampling, orbital and biomedical experiments.
The crew spent 22 hours on the lunar surface in total.
This sharp image was taken by Cernan as he and Schmitt roamed the valley floor.
The image shows Schmitt on the left with the lunar rover at the edge of Shorty Crater, near the spot where geologist Schmitt discovered orange lunar soil.
The Apollo 17 crew returned with 110 kilograms of rock and soil samples, more than was returned from any of the other lunar landing sites. Now forty years later, Cernan and Schmitt are still the last to walk on the Moon.

A “hot start” in any variant of a jet engine refers to the circumstance where the manufacturer defined limiting temperature for start has been exceeded. … The most common reasons for a hot start include insufficient airflow through the compressor, incorrect fuel scheduling and slow engine acceleration.
What is hot start in gas turbine engine?
If the fuel is ignited before there is enough air flowing around the chamber, its temperature will increase dramatically and exceed the design limits of the combustion chamber and turbine blades, thus causing a failure. This condition is known as a hot start.
Will a hot start damage a turbine engine?
Exceeding temperature limits during a turbine start (a “hot start”) can cause severe engine damage requiring expensive repairs. … Reduced power assurance margins accompanied by high start temperatures may indicate a dirty compressor. Fuel control adjustments can also affect start temperature.
What is the difference between hot start and hung start?
Motor the engine long enough to purge all the fuel and hot gas from the combustor and allow airflow to cool the hot section. A hung start occurs when the engine starts but doesn’t accelerate to idle speed.
What is a hot start procedure?
Aircraft Systems, General Aviation. There is a hot start procedure at my flight school that requires the throttle to be placed half way before turning on the fuel pump, as this apparently allows air to be pumped into the cylinders to even out the ratio of excess fuel already in the system with more air.
What is a wet start jet engine?
A faulty start of a gas turbine engine in which ignition fails to take place or a self-sustaining RPM is not achieved. The unburned or burning fuel is ejected from the tailpipe.
Is the air coming out of a jet engine hot?
The engine needs air suction first, then the air is squeezed or compressed, after that the mix of air and fuel ignites, resulting in airflow. … In a healthy jet engine in operation, the temperature in the combustion chamber can reach about 1,400 degrees Celsius or 2,552 degrees Fahrenheit. We think that’s pretty hot!
What is a hung start?
A hung start occurs when the engine lights off normally but doesn’t accelerate to idle RPM. This is usually the result of insufficient power to the engine from the starter. Live from the Flight Deck.
What does creep of the turbine blades mean?
Creep is the natural tendency of a material to gradually move or permanently deform as a result of mechanical stress or strain. … For turbines, creep can cause the blades to elongate, which can ultimately lead to the blade beginning to damage or pierce the turbine casing.
What is a hung stall?
Hung stall: after compressor stall, engine fails to recover immediately. … The formation of ice on inlet guide vanes, stators, and compressor blades can result in reduced clearance and interference damage. Post-crash evidence may include FOD-type damage.
What is N1 and N2 in a jet engine?
N1 and N2 express the rotational speed of turbine engines as a percentage of the maximum normal operating RPM. N1 is the speed of the low pressure spool and serves as the primary power setting, and N2 is the speed of the high pressure spool which indicates if aircraft systems have sufficient power.
What is NG on a turbine engine?
Ng: Gas generator rotation speed indication. Ng is an indication of the power output of the engine. The pilots and technicians reference the Ng speed to determine the engine power setting.
Why is an ACU fitted to a gas turbine engine?
Why is an A.C.U fitted to a gas turbine engine?. Option A. It increases the rate of acceleration of the engine. … It limits the rate of increase in fuel flow during sudden acceleration.
What does Hot Start PCR do?
Hot Start PCR allows for reaction set up at room temperature without non-specific amplification and primer dimer formation. Whereas conventional PCR is often utilized to make exponential copies of your DNA target sequence without an additional temperature-sensitive reaction activation component.
What should be done initially if a turbine engine catches fire when starting?
64 (8171) – What should be done initially if a turbine engine catches fire when starting? A- Turn off the fuel and continue engine rotation with the starter. 65 (8172) – What is the proper starting sequence for a turbojet engine?

SINGAPORE, Oct. 8 (Xinhua) -- Singapore had offered to extend the deployment of two C-130 transport aircraft of the Republic of Singapore Air Force in the disaster-hit area of Indonesia's Sulawesi, said Singapore's Defence Minister Ng Eng Hen in his Facebook post on Monday evening.
He said the deployment would be extended "as long as Indonesia needs our help."
Ng said the two aircraft had been busy in Sulawesi, as they had flown 20 sorties, ferried more than 30 tons of supplies, and transported close to 400 displaced persons to better facilities for aid and treatment, over six days.
The city-state's defense ministry announced last week that two C-130 transport aircraft carrying humanitarian supplies were sent to Indonesia on Oct. 2, in support of the Indonesian government's disaster relief efforts following the earthquake and tsunami on Sept. 28.
The relief package comprises tents, meal rations, bottled water and medical supplies, worth approximately 240,000 Singapore dollars (about 174,620.4 U.S. dollars).
The two C-130s would remain in Indonesia following the delivery of the relief package, to support the Indonesian government to evacuate those displaced from disaster-hit areas, the ministry added. | Yes |

Supported by SPRINT, Omnidea Ltd will collaborate with the University of Leicester to develop a ground-breaking miniature solid fuel plasma-based electrical thruster for use on CubeSats.
The new thruster is a highly innovative electrical propulsion system for spacecraft applications and is the first system of its kind to generate plasma at thermonuclear temperatures and densities. It will be used for moving and positioning deployed space assets in vacuum and low-pressure environments, used on assets ranging from low Earth Orbit spacecraft (200-500km altitude) to deep space exploration systems. Omnidea Ltd is also planning to incorporate this technology into a new generation of rocket engines for use in Very Low Earth Orbit satellites, a relatively new market, still in its infancy.
The system works by generating a particular magnetic effect which results in a more tightly focused ion beam that gives higher performance when compared to traditional Pulse Plasma Thruster (PPT) systems. This results in higher specific impulse performance and higher energy efficiency operation.
The University of Leicester will bring its expertise in plasma physics, electronic circuit design and overall expertise in the space arena to this SPRINT project with Omnidea Ltd.
CubeSats equipped with these propulsion systems can also help with the mitigation and remediation of space debris - by avoiding collisions and removing themselves from orbit at end of life – thus enhancing mission performance.
This project with the University of Leicester will be funded by the £7.5 million SPRINT programme. SPRINT provides unprecedented access to university space expertise and facilities. SPRINT helps businesses through the commercial exploitation of space data and technologies.
Joe Wells, Omnidea Ltd UK Managing Director, said: “We are delighted to be collaborating with the University of Leicester and aim to maximise the innovation support it offers, whilst gaining access to key experts and the range of facilities at the University’s Space Research Centre.
“This research project will be extremely valuable in determining specifications for an in-orbit demonstrator and an equivalent breadboard demonstrator that will be built and tested in laboratory vacuum conditions.
“More significantly, we see this as an ideal opportunity to enter and exploit the small satellite market as an early player. This type of propulsion system has previously never been used in space applications. The technology combines the advantages of traditional PPT including simplicity, reliability, lower cost and low power consumption, with improved performance, including higher specific impulse, impulse bit and energy efficiency.”
Piyal Samara-Ratna, Space Park Leicester’s METEOR centre Principal Engineer added: "Omnidea’s electronic propulsion capability will revolutionise the way that small spacecraft are deployed in space.
“SPRINT has enabled us to collaborate with Omnidea on this innovative project, allowing us to enter the electronic propulsion sector, leverage our core research skills and knowledge, and apply this to space systems. SPRINT will help to develop an initial proof of concept and accelerate this development into a commercially viable system.” | Yes |
A manned capsule escape test is not the first (or third) thing they would launch on NG.
By that time they should(tm) have one or more well used 1st stages. Then add a stock 2nd stage and do the test for real. Maybe do that launch partially fueled to keep the environmental impact small.
Blue is primarily interested in selling seats to tourists, they need to convince the public that their safety systems work. Easiest to do that using the actual flight configuration. For NASA they could go with a cobbled up rocket and try to save some money, but that is more difficult to explain. Also, once the booster is "free" the cost for such a test go down by a good margin. - If reuse does not work out Blue has a bigger problem.
Convincing the public is why I think that we may see another NS abort test in the future, once a booster and capsule combination reaches their end of life. Reinforcing the message that the safety systems work as intended over the full lifetime of the system. | Yes |

Blogger Aslan has paid a visit to the aircraft repair plant of Rzhev, Russia, to make a report about mass modernization of MiG-31 fighters. His pictures are presented in this post.
There are about 10 aircraft on the conveyor of the assembly shop. Upon full disassembly and assembly, they will be sent to a painting shop.
An aircraft is fully disassembled, all units are repaired and tested, and when necessary – replaced with new ones.
The main problem that might occur is a short supply of some parts required for production.
They have an additional facility for wing and empennage repair.
The MiG-31 was phased out of production in 1994, the average service life of such aircraft exceeds 25 years. When such a period expires an aircraft has to go through an overhaul that provides a guaranteed extra 30 years of normal service.
Specialists believe that the operation time of its airframe may reach 40 years.
They have been preparing for this modernization since 2006.
They have a lot of orders, but the modernization of MiG-31 is their top priority.
Modernization of 50 units of MiG-31BM is to be completed by the end of 2018.
Modernization includes new avionics, digital data channels, radar and cabin improvement (multifunctional color displays), new powerful “smart” bombs, air-to-air missiles, anti-radar missiles. The detection range of the new radar is 320 km, it may track up to ten targets at the same time.
MiG-31 became the replacement of MiG-25 that had been developed to oppose American bombers B-70 and SR-71 jets.
While modernizing MiG-31 they made necessary corrections to eliminate the shortcomings of MiG-25 so the new fighter turned into a very impressive interceptor.
MiG-31 is not a very maneuverable aircraft but a rather speedy one (up to 3000 km/h). Its combat radius is 720 km, which is not too much, in fact.
About 500 units of MiG-31 were made back in the 80s. In fact hundreds of MiG-31 aircraft that Russia has today could be updated to the level of MiG-31M or 31BM.
The service life after modernization is about 10-15 years.
In the painting shop.
Something seems to be lacking..
Oh, bright colors were missing!
The bottom of the body will be a bit lighter…
They use sprayguns for coloring.
Presently, the plant repairs and modernizes the following aircraft: MiG-31, Su-24, MiG-29, their components and detachable equipment.
Aircraft repair plant No. 514 is a big enterprise that repairs and modernizes front-line aircraft and has 72-years experience in military aviation equipment repair.
Millimeter after millimeter…
The most delicate work is done by women.
ARZ engines are waiting for their owners.

The Qatar Airways plane landed as an emergency after the pilot was allegedly handed a note warning of a device on board.
Greater Manchester Police later posted on their official Twitter account: "Passengers now being allowed off the plane at @manairport. One passenger still with officers and incident still being dealt with.
"A man who was onboard the plane at @manairport has been arrested on suspicion of making a hoax bomb threat."
One passenger tweeted what was apparently a picture of a man being led off the plane by armed police.
Eyewitnesses in the area reported seeing several police and fire vehicles around the airport.
Chief Superintendent John O'Hare, of Greater Manchester Police, said: "Today's incident at the Manchester Airport has received widespread coverage and interest so it is right we update everybody.
"We can confirm the incident is over and it's business as usual at the airport."
He continued: "The incident arose when the pilot received information about a possible device on board the plane, having been handed a note from a passenger.
"As a result, a full emergency activation commenced that involved the aircraft being escorted in by the RAF before specialist officers boarded and subsequently made an arrest.
"A 47-year-old man from the North West has been arrested on suspicion of making a bomb hoax and remains in police custody for questioning.
"A full search of the aircraft has now finished and nothing suspicious was found."
A spokeswoman from National Air Traffic Services confirmed a military aircraft escorted a plane into land but could not give further informatiion.
Witness Paul Bell, who was on his way to the airport in a taxi, told Sky News that he saw the RAF Typhoon meet the passenger plane.
He said: "We heard the fighter jet circling over Stockport, and literally 10 minutes later we saw the plane coming in being followed by it.
"We saw the (RAF Typhoon) coming in, literally flying around the aeroplane.
"It then pinged up on the sat nav that the airport is on lock-down.
"There are lots of people hanging around, checking their phones. We're stuck in a massive traffic jam. There are no planes landing or taking off." | Yes |
NASA has always sent probes into the universe, but it is about to start sending humans into space again.
The first Artemis I mission, an uncrewed expedition around the moon, is scheduled to leave Earth as early as August 29.
The first leg of that trip, which NASA hasn't undertaken since the last Apollo mission in 1972, starts Tuesday with the slow crawl of the rocket and spaceship to the launchpad.
The first four miles of NASA's return to the moon are referred to by mission leaders, according to Michael Bolger, exploration ground systems manager at Kennedy Space Center.
You can watch a live broadcast on NASA's Kennedy Space Center channel. The live stream starts at 3 pm. The roll begins at about 9 p.m. on August 16. E.T.

It's been a long time since a rocket of this size was used by NASA. It's expected that the first crewed flight to Mars will happen one day, thanks to the SLS rocket. In the future, it could be possible to take a robotic scientific journey to the planets.
Artemis I, the first in a series of planned voyages named after the Greek goddess and twin of Apollo, is a more than $4 billion launch to fly the Orion capsule farther than any spaceship built for humans has ever flown.
The United States will be able to send a crew on the next mission, Artemis II, if this test mission is anything to go by. During Artemis III, the first moonwalk of a woman and person of color is expected to take place.

Artemis I will fly a total of 1.3 million miles, which includes 40,000 miles beyond the moon. The capsule will splash down in the ocean after liftoff. Bill Nelson, NASA's administrator, said that the primary purpose of the first mission is to test the ability of the Navy to recover from reentering Earth's atmosphere.
"Orion will come home faster and hotter than any other craft has before." It is returning at 32 Mach. At 32 times the speed of sound, it will hit the Earth's atmosphere. "It's going to dip into the atmosphere and bleed off some of that speed before it starts descending through the atmosphere," said the former astronauts during a briefing. We were at 25 Mach on the Space Shuttle.
The big moon rocket needs to warm up. On its crawl to the launchpad, it won't travel over 1 mph. | Yes |
Navy: Training jet flew too low for thrills before crash
NASHVILLE, Tenn. (AP) - The Navy is citing pilot error for a military training jet crash in Tennessee that killed the two aboard, saying it was being flown for thrills and too low.
Navy officials say in a report the T-45C Goshawk was flying below allowable altitudes last October when it plunged into woods near Tellico Plains.
The crash killed 31-year-old instructor Lt. Patrick Ruth from Metairie, Louisiana, and 25-year-old student pilot Lt. J.G. Wallace Burch from Horn Lake, Mississippi. Both were stationed at Naval Air Station Meridian in Mississippi.
The report cites a "culture" within the individual training unit and Naval air training at large that allowed pilots to fly "beyond the bounds" of approved Naval Air Training Command curriculum. It also says leadership failed to ensure training operations adhered to approved publications.

LA PAZ, BOLIVIA — Supported by planes, hundreds of soldiers searched remote areas of the Andean foothills for pieces of a missing Russian space probe that carried radioactive material.
The soldiers are looking for tiny capsules of radioactive plutonium fuel that could have fallen in southwestern Bolivia or northern Chile, the government said Friday.
The Russian Embassy said the Mars-bound spacecraft probably disintegrated as it fell and that some small parts may have landed on land.
They said that the 9 1/2 ounces of plutonium-238 on board was contained in four capsules, about the size of film canisters, designed to withstand the searing heat of reentry into the atmosphere.
The spacecraft fell in two pieces Nov. 16 and 17 after its fourth-stage booster rocket failed to propel it out of the Earth's orbit. | Yes |
