Arabsat-6A. Arabsat-6A is a geostationary communications satellite operated by Arabsat. The satellite was built by Lockheed Martin Space Systems on a modernized A2100 bus. The satellite was successfully launched from Kennedy Space Center LC-39A aboard Falcon Heavy on April 11, 2019.

History 
Arabsat-6A and SaudiGeoSat-1/HellasSat-4 are the two satellites of the Arabsat-6G program, ordered by the Arab League to supply the communications needs of member states.

Contracts to build the two satellites were awarded to Lockheed Martin Space Systems in April 2015. Arabsat ultimately awarded the launch contract for Arabsat-6A to SpaceX for a Falcon Heavy flight with no expendable boosters. The Falcon Heavy was chosen over the Falcon 9 due to its far superior thrust; the extra boost would extend the satellite's operational lifespan from 15 years to 18-20 years.

Spacecraft 
Arabsat 6A is based on an updated version of the A2100 bus and is considered among the most advanced communications satellites built. The spacecraft utilizes fixed and steerable Ku-band and Ka-band transponders to provide TV and radio services to the Middle East and North Africa from its station at 30.5°E.

Launch 
Arabsat-6A was launched aboard the first operational Falcon Heavy on 11 April 2019 at 22:35 UTC from Kennedy Space Center LC-39A. Following a successful launch, the twin side boosters separated from the center core and returned to land at Landing Zones 1 and 2, while the center core completed its mission and landed on Of Course I Still Love You. En route to port after a successful landing, the center core tipped over in the rough seas, and was destroyed. Approximately 34 minutes after launch, the Arabsat-6A was released from the second stage and began a 17-day process to reach its operational orbit.

On June 15, 2021, the 4-tonne second stage re-entered the Earth's atmosphere, its orbit having gradually decayed due to atmospheric drag, with an uncontrolled splash down in the Coral Sea east of Australia

John Read (inventor). John Read was a British physicist and inventor. He developed a rotating doubler electrostatic generator, used to produce static electricity, which he called a 'spectacle doubler' because it involved discs of glass. His work was based on William Nicholson's doubler.

Reid lived in Knightsbridge, London and taught at the Knightsbridge Charity School.

He made observations of the atmospheric electric field, which he observed behaved differently in different air quality conditions, in 1791 and 1792. This phenomenon is now understood as originating from the global electric circuit.

Richard Lovett was the first British academic to publish Read's letters after his death.

Nautical cable. A nautical cable is a band of tightly woven and clamped ropes, of a defined cable length, used during the age of sail for deep water anchoring, heavy lifting, ship to ship transfers and towing during blue sea sailing and other uses.

Waterproof lines

Ordinary rope is not waterproof. When a ship anchors in relatively deep water (greater than about ), the anchor and rope that is let down becomes drenched with water, becoming prohibitively difficult to raise again, even with a mechanism like a capstan. This ultimately limits the depths available with  ordinary rope to within the weight bearing capacity of the rope. The rope will become so heavy with water it will break. 

The traditional instructions, according to the British Royal Navy in the age of sail, are: Three large strands of tightly woven rope of about  in length are themselves tightly woven in a direction counter to the weave, or twist, of the rope and clamped together over intervals to provide one strong length of rope that is effectively waterproof.  The three ropes are so tightly wound counter to the weave of the constituent ropes that the fibers are compressed and the individual weaves stressed, sealing out the water and resulting in a length of about , the UK traditional definition of cable length.  Using a cable, the raising of the anchor, or any activity involving submerging the cable, is not more strenuous than lowering.

Hawsers 

Hawsers are not cables.  Hawsers are ropes of arbitrary length woven together to increase the strength of the overall line, but are not considered waterproof as the weave of the hawser goes with the weave of the constituent ropes. This has come to be known as "hawser laid" and "cable laid".  Confusion between cables and hawsers is rampant because both cables and hawsers can be used through the hawsehole.

KDDX-class destroyer. The Korean Next-Generation Destroyer (KDDX) is a next generation stealth guided-missile destroyer under development by Hyundai Heavy Industries for ROK Navy, to be launched after 2025. Displacement of the class is set to be about 8,000 tons, length 155 meters, breadth 18.8 meters and draft 9.5 meters. Will feature KVLS to  launch Hyunmoo-3C land-attack cruise missiles and SSM-700K anti-ship missiles. At 8000 tons displacement, it will be lighter than Sejong the Great-class destroyers, but with more advanced sensors and stealth characteristics and lower operating costs. The ships will have advanced missile defense.  The  size  of  this  new  destroyer  would  be  between  that  of  the  currently operating 4,200-ton KDX-II and the Aegis Destroyer KDX-III, and would be assigned to a naval task force. The total cost of developing and producing the six vessels is expected to top $6.2 billion.

History 
The project was unveiled back in 2009 next-generation during the 2009 Navy Audit and was supposed to be equipped with SM-2 surface-to-air missiles and SPY-based radars that would slot in between the Chungmugong Yi Sun-sin-class destroyer (KDX-II) and Sejong the Great-class destroyer (KDX-III).  

In 2012, it was again confirmed that the Republic of Korea Navy would procure six next-generation destroyers and the project being renamed from KDX-IIA to KDDX in the Basic Plans for Defense Reform (2012-2030) and that it would be built after 2020.  But by 2013, it was decided to procure three more destroyers under a new subclass of the Sejong the Great-class destroyer named KDX-III Batch II (Jeongjo the Great) and the funding and priority allotted for the KDDX was shifted to the new batch of AEGIS-equipped destroyers. 

In 2018, the 118th Defense Program Promotion Committee approved the Basic Strategy for the Promotion of the Korean Next Destroyer (KDDX) Project  and by 2019, work began on its initial basic design and its development. 

During MADEX 2019, both HD Hyundai Heavy Industries and Hanwha Ocean (then known as Daewoo Shipbuilding & Marine Engineering) displayed their proposal for the KDDX program.
