SpaceX launched a rescue mission for the two stuck astronauts at the International Space Station on Saturday, sending up a downsized crew to bring them home but not until next year.
The capsule rocketed into orbit to fetch the test pilots whose Boeing spacecraft returned to Earth empty earlier this month because of safety concerns. The switch in rides left it to NASA’s Nick Hague and Russia’s Alexander Gorbunov to retrieve Butch Wilmore and Suni Williams.
Because NASA rotates space station crews approximately every six months, this newly launched flight with two empty seats reserved for Wilmore and Williams won’t return until late February. Officials said there wasn’t a way to bring them back earlier on SpaceX without interrupting other scheduled missions.
By the time they return, the pair will have logged more than eight months in space. They expected to be gone just a week when they signed up for Boeing’s first astronaut flight that launched in June.
NASA ultimately decided that Boeing’s Starliner was too risky after a cascade of thruster troubles and helium leaks marred its trip to the orbiting complex. The space agency cut two astronauts from this SpaceX launch to make room on the Dragon capsule’s return leg for Wilmore and Williams.
Wilmore and Williams watched the liftoff via a live link sent to the space station, prompting a cheer of “Go Dragon!” from Williams, NASA deputy program manager Dina Contella said.
Williams has been promoted to commander of the space station, which will soon be back to its normal population of seven. Once Hague and Gorbunov arrive on Sunday, four astronauts living there since March can leave in their own SpaceX capsule. Their homecoming was delayed a month by Starliner’s turmoil.
Hague noted before the flight that change is the one constant in human spaceflight.
“There’s always something that is changing. Maybe this time it’s been a little more visible to the public,” he said.
