NASA astronauts Butch Wilmore and Suni Williams inspect safety hardware aboard the International Space Station. NASA The two NASA astronauts who launched to the International Space Station (ISS) on board Boeing’s Starliner spacecraft will have to wait even longer to return home. NASA delayed the launch of a SpaceX Dragon spacecraft, designated as the Starliner astronauts’ ride home. Originally set for liftoff in February 2025, NASA’s SpaceX Crew-10 will launch no earlier than late March 2025 to “complete processing on a new Dragon spacecraft for the mission,” the space agency wrote in an update. The new Dragon spacecraft will arrive at SpaceX’s processing facility in Florida in early January. “Fabrication, assembly, testing, and final integration of a new spacecraft is a painstaking endeavor that requires great attention to detail,” Steve Stich, manager of NASA’s Commercial Crew Program, said in a statement. After launching to the ISS with the Crew-10 astronauts, the Dragon spacecraft will be used to transport the SpaceX Crew-9 mission back to Earth. That includes NASA astronauts Nick Hague, Suni Williams, Butch Wilmore, and Roscosmos cosmonaut Aleksandr Gorbunov. Williams and Wilmore launched to the ISS on June 5 on board Boeing’s Starliner for the first crewed test flight of the spacecraft. Starliner’s journey to the ISS was less than ideal; five of the spacecraft’s thrusters failed and the spacecraft developed five helium leaks, one of which was identified prior to liftoff. The crew capsule remained docked to the ISS for months while NASA and Boeing debated whether or not Starliner is fit to return the astronauts to Earth safely. Mission teams ultimately decided to return an uncrewed Starliner and bring back its crew on board a SpaceX Dragon spacecraft. This marked a severe blow to Boeing’s Starliner program, but it also meant that the two astronauts would have to spend an unexpectedly long time on board the ISS. The Starliner crew was originally meant to be in space for a week or so, but the astronauts were now forced to spend months living and working in the space station. The most recent delay of the Crew-10 launch is yet another month added to Williams and Wilmore’s unplanned time in space.
