The launch of NASA’s SpaceX Crew-12 mission, which includes astronauts Jessica Meir, Jack Hathaway, ESA astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev, has been delayed due to unfavorable weather conditions. Originally set for February 11, 2026, the launch will now take place no earlier than February 13, 2026, at 5:15 a.m. EST (1015 UTC).
Weather Constraints Impacting Launch
NASA and SpaceX officials determined that the weather along the ascent corridor was unacceptable for a safe launch. Steve Stich, NASA’s Commercial Crew Program Manager, indicated that high winds, reaching up to 24 to 28 knots, posed significant risks, particularly in the staging area. A low-pressure system was identified as the cause of these winds, which the weather models consistently supported over the preceding 24 hours.
Launch Preparations and Priorities
As the Crew-12 mission awaits its new launch date, SpaceX is also preparing for other missions, including a Vulcan rocket launch by United Launch Alliance (ULA) scheduled for February 11. Stich confirmed that Crew-12 would take priority on the Eastern Range, allowing ULA to proceed with its launch only if conditions permitted.
Mission Timeline and Future Options
Should the launch on February 13 not occur, NASA has identified potential launch windows from February 15 to 17. The Crew Dragon spacecraft, nicknamed Freedom, is expected to dock with the International Space Station (ISS) approximately 3:15 a.m. EST (0815 UTC) on February 14, assuming the launch proceeds as planned. However, a launch on February 14 would result in a longer transit time to the ISS, estimated at around 42 to 44 hours.
Technical Readiness and Rehearsals
In preparation for the launch, SpaceX conducted a static fire test of the Falcon 9 rocket, identifying and replacing a sluggish check valve that could have affected performance. William Gerstenmaier, SpaceX’s vice president of Build and Flight Reliability, noted that this diligence is crucial for ensuring the vehicle’s readiness.
A successful dry dress rehearsal was conducted on February 9, confirming that the launch team is well-prepared for the upcoming mission. Gerstenmaier emphasized the importance of this rehearsal, particularly as it marks only the second crewed launch from pad 40.
As the countdown continues, NASA and SpaceX remain focused on ensuring a safe and successful launch for Crew-12, with ongoing assessments of weather conditions and technical readiness.
