NASA and SpaceX Postpone Crew-10 Mission to Retrieve Stranded Astronauts

Hydraulic Issue and Weather Concerns Prompt Delay / Reuters

NASA and SpaceX have delayed the highly anticipated Crew-10 mission launch, originally set to send a replacement crew to the International Space Station (ISS) and facilitate the return of U.S. astronauts Butch Wilmore and Suni Williams, who have been stranded in orbit for nine months due to complications with Boeing’s Starliner spacecraft. The postponement stems from a hydraulic system malfunction in a ground support clamp arm for the Falcon 9 rocket, identified just before the scheduled liftoff from Kennedy Space Center in Cape Canaveral, Florida. Compounding the issue, unfavorable weather forecasts, including high winds and rain along the Dragon spacecraft’s flight path, led mission managers to wave off an attempt the following day, pushing the next possible launch window to no earlier than 7:03 p.m. EDT on Friday. This SpaceX Crew-10 mission delay has ripple effects, rescheduling the Crew-9 team’s departure, including Wilmore and Williams, to Wednesday, March 19, provided the new timeline holds. Launch teams are actively troubleshooting the hydraulic glitch, with NASA emphasizing safety as the top priority for this critical astronaut rotation mission.

The Crew-10 mission, featuring a seasoned quartet of astronauts, NASA commander Anne McClain, pilot Nichole Ayers, JAXA’s Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov, was poised to blast off aboard the SpaceX Dragon spacecraft Endurance, a veteran of three prior missions: Crew-3, Crew-5, and Crew-7. This spacecraft swap occurred after delays in preparing a new Dragon capsule, C213, prompted NASA to expedite the timeline by two weeks, a decision influenced by public calls from President Donald Trump and SpaceX CEO Elon Musk for an earlier retrieval of Wilmore and Williams. Their extended ISS stay began in June 2024, when they launched as the inaugural test crew for Boeing’s Starliner under a $4.5 billion NASA contract, only to face propulsion system failures that rendered their return on that craft too risky. Consequently, NASA pivoted to SpaceX’s reliable Crew Dragon, operational since 2020 under a similar $4 billion deal, to bring them home, spotlighting the contrasting trajectories of these competing commercial crew programs.

Wilmore and Williams, both U.S. Navy test pilots with extensive astronaut experience, have adapted to their prolonged mission, contributing to ISS research and maintenance alongside Crew-9 members Nick Hague and Aleksandr Gorbunov. In a recent March 4 call, Williams shared her excitement about reuniting with her family and dogs, noting the emotional toll on loved ones back home while describing their daily work in space as engaging and enjoyable. Their safe return hinges on Crew-10’s successful arrival, as ISS staffing protocols require a sufficient U.S. presence for ongoing operations, meaning Wilmore and Williams must await their replacements before departing in the Crew-9 Dragon, docked since September 2024. The SpaceX Crew-10 mission delay thus extends their orbital tenure, originally planned as an eight-day test flight, into a nine-month odyssey, drawing attention to the complexities of space travel logistics.

Adding an unusual twist, political pressure from Trump and Musk has framed this NASA SpaceX astronaut retrieval mission as a point of contention, with the duo alleging, without evidence, that former President Joe Biden’s administration bears responsibility for the delay. This intervention, shifting the launch from a late March target to mid-month, underscores the intersection of space policy and public discourse, though NASA maintains its decisions prioritize technical readiness over external influence. The agency’s meticulous preparations included a Launch Readiness Review on March 11, affirming a “go” status, and a Delta Flight Readiness Review to finalize details, only for the hydraulic issue to emerge hours before liftoff. Detailed timelines had crew suiting up at 3:48 p.m. EDT, walking out at 4:28 p.m., and entering the Dragon by 5:13 p.m., plans now deferred as teams reassess.

Boeing’s Starliner woes further contextualize this SpaceX Crew-10 mission delay, as the spacecraft, intended to rival Crew Dragon, has faced engineering setbacks and cost overruns since 2019, lagging far behind its competitor. The June 2024 test flight marked Starliner’s first crewed outing, a milestone overshadowed by its inability to safely return Wilmore and Williams, thrusting SpaceX into the spotlight as NASA’s dependable ISS transport provider. With a potential launch now eyed for Friday, subject to weather and technical resolutions, the SpaceX Crew-10 mission update remains fluid, with NASA and SpaceX poised to provide further clarity.
