Within the unlikely occasion an area emergency arises on the area station within the close to future, two astronauts must experience house with out spacesuits.
Boeing’s Starliner spacecraft is ready to depart the Worldwide Area Station (ISS) empty no sooner than tomorrow (Sept. 6). It carried NASA astronauts Butch Wilmore and Suni Williams as much as the ISS and was anticipated to carry them house in Boeing-made spacesuits. However after Starliner’s propulsion system acted up throughout docking with the ISS June 6, NASA ultimately concluded that placing the astronauts on board for a return can be an excessive amount of of a danger.
For a number of weeks, a SpaceX spacecraft that flew the Crew-8 mission to the ISS would be the emergency automobile out there for Williams and Wilmore if the orbiting complicated wants evacuation. However the Starliner fits should not appropriate with SpaceX’s Crew Dragon spacecraft, NASA industrial crew supervisor Steve Stich instructed reporters throughout a teleconference yesterday (Sept. 6). “So in a brief scenario, we might not have fits for Butch and Suni on Dragon,” he defined.
SpaceX and Boeing are the 2 industrial distributors tasked with sending up American-launched astronauts to the ISS. Every firm not solely has its personal spacecraft, however its personal spacesuits. (Russia additionally has its personal spacecraft and spacesuits for the Soyuz spacecraft, which launches and lands crews from Kazakhstan.)
Crew-8 already has 4 spacesuited astronauts occupying its 4 seats as they conclude a half-year mission in area: NASA’s Matthew Dominick, Michael Barratt, Jeanette Epps and Roscosmos cosmonaut Alexander Grebenkin. If required, Williams and Wilmore would experience house with the Crew-8 astronauts on the cargo pallet beneath their Crew Dragon spacecraft’s seats.

As Crew Dragon is totally pressurized, there are not any nominal points for the 2 Starliner astronauts on board, however the tiny danger of depressurization might pose a crucial danger.
Such an accident has occurred earlier than, when the Soviet Union’s Soyuz 11 crew of three died throughout touchdown after a valve popped open of their spacecraft; not one of the cosmonauts was sporting a spacesuit.
On NASA’s facet, all crews have been spacesuited for launches and landings for the reason that deadly Challenger area shuttle launch catastrophe of 1986 that killed seven astronauts.
However the probabilities of Wilmore and Williams having to experience house with out fits are shrinking every day, as Crew-8’s standby position for Starliner won’t final for lengthy. Crew-9, the following SpaceX astronaut mission for NASA, is ready to launch no sooner than Sept. 24 for a traditional ISS half-year mission. Crew 9’s Crew Dragon will launch with solely two astronauts, as a substitute of the deliberate 4, to make room for Williams and Wilmore. One spacesuit may also be shipped to the ISS sized for Wilmore, as Williams can use a SpaceX swimsuit on board ISS.
“We do have one swimsuit on orbit proper now that matches Suni, and he or she’s tried that swimsuit on, and it suits properly. That is a SpaceX swimsuit,” Stich stated. “After we [NASA] arrange the contract, we let every of the contractors to seek out their very own fits and their very own interface, after which we’re sending up a swimsuit for Butch that may fly up on Crew-9.”
Crew-9’s Crew Dragon will function the emergency evacuation for the 4 astronauts manifested to fly house on it: Wilmore, Williams, NASA astronaut and Area Pressure Guardian Nick Hague, and Roscosmos mission specialist Aleksandr Gorbunov. The nominal plan requires the quartet to return to Earth in February 2025, after Hague and Gorbunov spend about 5 months in area and Wilmore and Williams, eight months.
