NASA Astronauts at International Space Station Welcome SpaceX Capsule for Return Home Next Year

Two astronauts, who have been at the International Space Station since June, received their new return vehicle with the arrival of a SpaceX capsule on Sunday. SpaceX launched this rescue mission on Saturday, including two astronauts and two empty seats for Butch Wilmore and Suni Williams. These seats are reserved for their return next year.

The Dragon capsule successfully docked in darkness over Botswana, with both crafts orbiting 420 kilometres above Earth. NASA had switched Wilmore and Williams to SpaceX due to safety concerns with their Boeing Starliner capsule. The first crewed Starliner test flight faced thruster failures and helium leaks after liftoff, prompting NASA to deem it too risky for the test pilots' return. Consequently, Starliner returned to Earth without passengers earlier this month.

SpaceX's Role in Astronaut Transport

SpaceX has been providing transport services since its first astronaut flight in 2020. NASA also engaged Boeing for ferry flights after retiring space shuttles. However, software issues and other problems with Starliner caused years of delays and over USD 1 billion in repairs. Inspections of Starliner are ongoing at NASA's Kennedy Space Center, with data reviews starting this week.

The Dragon capsule, carrying NASA's Nick Hague and Russia's Alexander Gorbunov, will stay at the space station until February. This extends what was supposed to be a weeklong trip for Wilmore and Williams into an eight-month mission. To accommodate Wilmore and Williams on the return journey, two NASA astronauts were removed from the mission.

Impact of Delays on Current Missions

The arrival of two new astronauts allows the four who have been aboard since March to return to Earth soon in their own SpaceX capsule. Their stay was extended by a month due to issues with Starliner. Although Saturday's launch was successful, SpaceX reported that the rocket's upper stage ended up outside its intended Pacific impact zone due to an engine misfire. As a result, Falcon launches are paused until the issue is resolved.

NASA prefers to rotate its station crews approximately every six months. Despite current challenges, "We're a long way from saying, 'Hey, we're writing off Boeing,'" said Jim Free, NASA's associate administrator, during a pre-launch briefing.
