What is Orion? Orion is NASA’s new spacecraft, built to take humans farther into space than they’ve ever gone before. It will carry the crew to space, provide emergency abort capability, sustain the crew and provide a safe return to Earth. Having completed its first successful flight test in December 2014, Orion's next milestone will be a flight beyond the orbit of the moon.
 Flight Tested
  first launch On Dec. 5, 2014, Orion launched atop a Delta IV Heavy rocket from Cape Canaveral Air Force Station's Space Launch Complex 37.
 Orion Flight Test Loaded with almost 1,200 sensors, Orion completed a two-orbit, 4.5-hour flight to test many of the systems most critical to safety before it carries astronauts.
 In the future Orion will launch on NASA’s new heavy-lift rocket, the Space Launch System. More powerful than any other rocket ever built, SLS will be capable of sending humans to an asteroid and eventually to Mars.
 Building on History NASA is using new technology and lessons learned from earlier missions to build the new spacecraft. Orion will carry up to six astronauts compared with Apollo's three, and a new version of the Apollo heat shield will keep the astronauts safe as the crew module re-enters Earth's atmosphere when it returns from deep space.  Orion will use more modern technology in many other areas, such as computers, electronics, life support and propulsion.
 Orion builds on the Space Shuttle design
  Space Shuttle Technology Orion's 970 outer tiles are made of the same material as the tiles that protected the shuttle.
 Service Module The European service module on Orion's second flight will use refurbished engines from the shuttle program.
 Crew Seats The crew seats that will fly on future missions will incorporate advances from the shuttle program to reduce mass but still protect the crew.





Journey to Mars
  International Space Station Photo of International Space Station from orbit. The human Journey to Mars begins some 250 miles overhead, as astronauts aboard the International Space Station are working off the Earth for the Earth. The space station's microgravity environment makes research possible that can't be achieved on Earth, leading to breakthroughs in understanding Earth, space and physical and biological sciences, including how future crews can thrive on longer missions, including round-trip journeys to an asteroid and Mars. The space station also is a test bed for exploration technologies like autonomous refueling of spacecraft, advanced life support systems and human/robotic interfaces. A portion of the space station has been designated a national laboratory, and NASA is committed to using this unique resource for wide-ranging scientific research. A new generation of U.S. commercial spacecraft and rockets are supplying cargo to the space station and will soon launch astronauts once again from U.S. soil.
 Robotic Explorers Curiosity rover self-portrait on Mars. A fleet of robotic spacecraft and rovers already are on and around Mars, dramatically increasing our knowledge about the Red Planet and paving the way for future human explorers. The Mars Science Laboratory Curiosity rover measured radiation on the way to Mars and is sending back radiation data from the surface. This data will help us plan how to protect the astronauts who will explore Mars. Future missions like the Mars 2020 rover, seeking signs of past life, also will demonstrate new technologies that could help astronauts survive on Mars.
  Space Launch System Artists Illustration of Space Launch System taking off through the clouds on it's way to deep space. NASA’s Space Launch System, or SLS, is an advanced launch vehicle for a new era of exploration beyond Earth’s orbit into deep space. SLS will launch astronauts in Orion on missions to an asteroid and eventually to Mars, while opening new possibilities for other payloads including robotic scientific missions to places like Mars, Saturn and Jupiter. Offering the highest-ever payload mass and volume capability and energy to speed missions through space, SLS will be the most powerful rocket in history.
 MARS Artists Illustration of astronaut boot and surface of Mars NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s. Mars is a rich destination for scientific discovery and robotic and human exploration as we expand our presence into the solar system. Its formation and evolution are comparable to Earth's, helping us learn more about our own planet’s history and future. Mars had conditions suitable for life in its past. Future exploration could uncover evidence of life, answering one of the fundamental mysteries of the cosmos: Does life exist beyond Earth?





Orion's First Flight Test Before we can send astronauts into space on Orion, we have to test all of its systems. There’s only one way to know if we got it right: Fly it in space.


The Flight Test Launch of Orion on Delta IV Heavy rocket For Orion’s first flight, no astronauts are aboard. The spacecraft is loaded with sensors to record and measure all aspects of the flight in every detail.
 Into Orbit Orion fairing separation seen from camera on spacecraft It all begins with the launch aboard a Delta IV Heavy rocket. As it punches into Earth orbit, Orion separates from its protective fairing (above), then jettisons its Launch Abort System. On future missions the Launch Abort System can pull Orion and its crew out of danger if there is a problem with the rocket during ascent.
  3,600 Miles Above Earth View of Earth from Orion in orbit After Orion completes one orbit of the Earth, the upper stage of the rocket fires again to start Orion on a climb to more than 3,600 miles above Earth. It passes through the Van Allen Belts, an area of dangerous radiation. Orion's shielding is put to the test as the vehicle cuts through the waves of radiation.
 Orion Separates Artist's Illustration of Orion Capsule separating from upper stage of rocket. The upper stage of the rocket triggers separation. Orion's jets fire to turn it into the proper position to re-enter Earth's atmosphere. At 75 miles above Earth, Orion travels at more than 20,000 mph.
   Re-entry Artist's Illustration of Orion Capsule re-entering the earths atmosphere. As Orion pushes air particles out of its way, those particles heat up. Temperatures around the vehicle reach 4,000 degrees Fahrenheit. This may be the most dangerous part of the flight. During re-entry, Orion is in a fireball. Onboard systems ignite jets to keep the ship pointed correctly so that a specially constructed shield takes the full brunt of the inferno.
 Splashdown and Recovery Orion in Pacific after splashdown After re-entry, it is time for Orion to slow down. Even though its speed has dropped to about 300 miles per hour, that is still too fast to land safely in the ocean. Orion has specially designed parachutes to help slow the spacecraft down to a gentle pace, keeping things comfortable for a future crew.

Building and Testing  Welding Photo of the bulkhead and nose cone of the Orion spacecraft were welding. The bulkhead and nosecone of the Orion spacecraft were joined using friction stir welding at NASA's Michoud Assembly Facility in New Orleans. Nondestructive evaluations validated the strength and integrity of the weld before the spacecraft was prepped for ground testing in flight-like environments, including static vibration, acoustics and water landing tests.
