NASA made the decision to use the Boeing Starliner capsule to bring astronauts Butch Wilmore and Suni Williams back to Earth was considered too risky due to technical glitches during their journey to the International Space Station (ISS). The two astronauts had been stranded at the ISS since December, but with the arrival of a SpaceX capsule, they are now a step closer to returning home. SpaceX launched a rescue mission with a crew of two astronauts and two empty seats reserved for Wilmore and Williams, who are scheduled to return to Earth in February.
Following concerns over the safety of the Boeing Starliner capsule used for the outward journey, NASA switched Wilmore and Williams to SpaceX instead. The thruster failures and helium leaks that occurred after liftoff during the first Starliner test flight with a crew were deemed too serious and poorly understood to risk the test pilots’ return. As a result, Starliner returned to Earth empty earlier this month. The Dragon capsule, carrying NASA’s Nick Hague and the Russian Space Agency’s Alexander Gorbunov, will remain at the space station until February, extending what should have been a weeklong trip for Wilmore and Williams into a mission lasting more than eight months.
NASA had to make adjustments to the mission, pulling two astronauts to make room for Wilmore and Williams on the return leg. Williams, the space station commander, welcomed the new crew members once Hague and Gorbunov arrived at the ISS. NASA typically rotates station crews every six months, and SpaceX has been providing transportation services since its first astronaut flight in 2020. The space agency also hired Boeing for ferry flights after the retirement of the space shuttles, but issues with the Starliner, including flawed software and other technical problems, led to years of delays and costly repairs.
Post-flight inspections are currently underway for the Starliner capsule at NASA’s Kennedy Space Center, with reviews of the data set to begin this week. Despite the setbacks and challenges faced during the mission, NASA remains committed to ensuring the safe return of its astronauts from the ISS. The collaboration between SpaceX and NASA has been instrumental in providing reliable and efficient transportation services for crew members to and from the space station. As space exploration continues to evolve, advancements in technology and safety measures will be crucial in supporting future missions and ensuring the well-being of astronauts in space.
