The next mission of SpaceX’s Crew Dragon to the International Space Station (ISS) has been postponed by a month due to delays in completing a new spacecraft. This decision will extend the stay of some astronauts aboard the ISS, including two who have been there since June.
NASA announced on December 17 that the Crew-10 mission, initially scheduled for February, is now set to launch no earlier than late March. The delay stems from the need for additional time to finish the fabrication, assembly, testing, and integration of a new Crew Dragon capsule.
Crafting the New Dragon Capsule
“Fabrication, assembly, testing, and final integration of a new spacecraft is a painstaking endeavor that requires great attention to detail,” said Steve Stich, NASA’s Commercial Crew Program Manager. He commended SpaceX’s efforts to expand the Dragon fleet and the flexibility of the ISS crew in accommodating the delay.
The new Crew Dragon will be the fifth in SpaceX’s lineup of crewed spacecraft, complementing its three cargo Dragon vehicles. According to Sarah Walker, SpaceX’s Dragon Mission Management Director, the spacecraft was near completion as of July and was undergoing final work at SpaceX’s California facility. It is now expected to arrive in Florida for final preparations in January.
While NASA did not specify the exact reasons for the delay, it considered other options, including using an existing Crew Dragon or making adjustments to the launch manifest, before opting for the delay. Existing capsules, including Freedom, currently at the ISS, and Endeavour and Resilience, which recently returned from other missions, were not available for a February launch.
Crew Adjustments and Extended ISS Stay
The Crew-10 mission will proceed with its planned roster: Anne McClain and Nichole Ayers from NASA, Takuya Onishi from JAXA, and Kirill Peskov from Roscosmos.
The delay has implications for the Crew-9 mission, launched in late September with NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov. They were joined by NASA astronauts Suni Williams and Butch Wilmore, who have been on the station since June after arriving on Boeing’s CST-100 Starliner.
Originally, Williams and Wilmore were scheduled to stay for just over a week, but their time on the ISS will now extend to about 10 months. NASA had earlier decided to return the uncrewed Starliner to Earth due to concerns with its thrusters.
Despite the delay, NASA emphasizes that Williams and Wilmore are not “stranded” as they can return to Earth in an emergency. Their extended stay is tied to the decision to use the new Crew Dragon for the upcoming mission, as preparing another vehicle was deemed impractical.
Looking Ahead
Assuming the Crew-10 launch proceeds in late March, the Crew-9 spacecraft is expected to return to Earth in early April after a handover period. This delay underscores the complexity of preparing new spacecraft while ensuring the safety and readiness of all missions.
As the new Crew Dragon nears completion, SpaceX and NASA remain focused on maintaining seamless operations aboard the ISS and advancing human space exploration.
