NASA astronaut Douglas Hurley is helped out of the SpaceX Crew Dragon Endeavour spacecraft onboard the SpaceX GO Navigator recovery ship after he and NASA astronaut Robert Behnken landed in the Gulf of Mexico off the coast of Pensacola, Florida, Sunday, Aug. 2, 2020. The Demo-2 test flight for NASA’s Commercial Crew Program was the first to deliver astronauts to the International Space Station and return them safely to Earth onboard a commercially built and operated spacecraft. Behnken and Hurley returned after spending 64 days in space.

Additionally, the crew may be deconditioned on landing, impacting their ability to independently egress the vehicles, perform post-landing tasks in a timely manner, and perform surface EVAs post-landing -including those required for emergencies.
