NASA Evaluates How Crew Will Exit Orion Spacecraft


When astronauts return to Earth from destinations beyond the moon in NASA’s Orion spacecraft and splashdown in the Pacific Ocean, they’ll still need to safely get out of the spacecraft and back on dry land. Using the waters off the coast of Galveston, a NASA and Department of Defense team tested Orion exit procedures on July 10-14, 2017.
