NASA Crew-9 astronauts Sunita Williams, Nick Hague, Butch Wilmore, and Russian cosmonaut Aleksandr Gorbunov breathed earthly air for the first time in over nine months on Wednesday after the successful splashdown of SpaceX's Dragon capsule. The astronauts disembarked the capsule on stretchers, as is customary, CNN reported. This precaution is taken by SpaceX for all astronauts returning from long-duration space missions.

Earlier, a worker rinsed the Crew Dragon spacecraft with fresh water to remove as much salt water as possible. "Saltwater is corrosive, and we want to try and rinse out as much of the salt water as possible to reduce that corrosion on the metallic structures," SpaceX's Kate Tice said. The side hatch of the Crew Dragon remains closed throughout its time in orbit. After docking with the ISS, astronauts enter and exit through a different hatch on top of the vehicle, CNN reported.
