After an extended stay aboard the International Space Station (ISS), NASA astronauts Sunita Williams and Butch Wilmore, along with their Crew-9 colleagues, are preparing to return to Earth sooner than initially anticipated. NASA and SpaceX have adjusted the return schedule, citing favorable weather conditions off the Florida coast.
The Crew-9 mission, which also includes NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov, is now targeting a splashdown on Tuesday, March 18, 2025. This revised schedule comes after careful assessment of weather patterns and a successful handover with the newly arrived Crew-10 astronauts.
Factors Influencing the Return
Several factors have played a crucial role in the decision to expedite the Crew-9 return:
- Weather Conditions:
- NASA and SpaceX mission managers conducted thorough evaluations of weather and sea conditions in the potential splashdown zones off the Florida coast.
- Favorable forecasts for Tuesday evening prompted the decision to move the return forward, aiming to avoid less favorable conditions predicted for later in the week.
- Crew Handover:
- The arrival of the SpaceX Crew-10 mission at the ISS on Sunday allowed for a necessary handover period.
- Completing this handover efficiently enabled the Crew-9 members to prepare for their departure.
- Operational Flexibility:
- The adjusted schedule provides increased operational flexibility, allowing for potential adjustments in case of unforeseen circumstances.

Extended Mission and Scientific Contributions
Sunita Williams and Butch Wilmore’s extended stay on the ISS resulted from complications with the Boeing Starliner spacecraft. Their time on the ISS has been a period of intense scientific research, contributing to a wide range of experiments. The crew will be bringing back valuable scientific data that will further research on earth.
It is important to note that due to the extended stay of Wilmore and Williams, they stayed on the ISS for roughly 9 months. This was due to issues with the Boeing Starliner spacecraft.
Live Coverage and Updates
NASA will provide comprehensive live coverage of the Crew-9 return, including key milestones such as hatch closure, undocking, and splashdown. This coverage will be available on NASA’s website and NASA+.
This return marks a significant milestone in the ongoing collaboration between NASA and SpaceX, demonstrating the reliability and efficiency of commercial crew transportation to and from the ISS.
