NASA astronaut Raja Chari climbs through a hatch of Lockheed Martin’s deep space habitat ground prototype at NASA’s Kennedy Space Center in Florida on March 25, 2019. Chari is one of the astronauts helping engineers refine requirements for the design of an American-made deep space habitat for the Gateway. Astronauts provide important design perspective as they may one day live and work aboard the lunar outpost, which would be located about 250,000 miles from Earth. To date, five habitat prototypes have been developed through NASA’s Next Space Exploration for Technologies Partnerships, or NextSTEP. Lockheed Martin was the first to turn their habitat over to NASA for testing. Ground prototypes developed by Bigelow Aerospace, Boeing, Northrop Grumman and Sierra Nevada Corporation will be tested in the future at various facilities across the country. A sixth company, NanoRacks, plans to develop a prototype as well.

CAPE CANAVERAL, Fla. -- Lockheed Martin crews assist as a crane is used to move the Orion ground test vehicle in the Operations and Checkout O&C Facility at NASA's Kennedy Space Center in Florida. The vehicle traveled more than 1,800 miles from the company's Waterton Facility near Denver where it successfully completed a series of rigorous tests that simulated launch and spaceflight environments. The ground test vehicle will be used for pathfinding operations in the O&C, including simulated manufacturing and assembly procedures. After those operations are completed, new backshell panels will be installed on the ground test vehicle at the O&C prior to the vehicle’s trek to NASA's Langley Research Center in Virginia for splashdown testing at the agency's Hydro Impact Basin. Launching atop NASA's heavy-lift Space Launch System SLS, which also is under development, the Orion Multi-Purpose Crew Vehicle MPCV will serve as the exploration vehicle that will carry astronaut crews beyond low Earth orbit. It also will provide emergency abort capabilities, sustain the crew during space travel and provide safe re-entry from deep space return velocities. For more information, visit www.nasa.gov/orion.

CAPE CANAVERAL, Fla. -- A view of one of the test stands in the Operations and Checkout O&C Facility at NASA's Kennedy Space Center in Florida where the Orion ground test vehicle has arrived. The vehicle traveled more than 1,800 miles from the company's Waterton Facility near Denver where it successfully completed a series of rigorous tests that simulated launch and spaceflight environments. The ground test vehicle will be used for pathfinding operations in the O&C, including simulated manufacturing and assembly procedures.

NASA began evaluating five habitat prototypes developed through NASA’s Next Space Exploration for Technologies Partnerships, or NextSTEP, to help engineers refine requirements for the design of an American-made deep space habitat for the Gateway. Lockheed Martin turned over its prototype to NASA, and testing began with crew on March 25, 2019, at Kennedy Space Center in Florida. Pictured inside the Space Station Processing Facility on March 26, 2019, from left are astronauts Shannon Walker and Stephanie Wilson. Astronauts are participating in the evaluations to provide their perspectives as those who may one day live aboard the lunar outpost, which would be located about 250,000 miles from Earth. Ground prototypes developed by Bigelow Aerospace, Boeing, Northrop Grumman, and Sierra Nevada Corporation will be tested in the future at various facilities across the country. A sixth company, NanoRacks, plans to develop a prototype as well.
