- After a medical issue involving one astronaut, SpaceX’s Dragon undocked from the International Space Station carrying four Crew-11 members
- NASA plans a pre-dawn splashdown off California, with live coverage of the reentry and landing scheduled.
- The station is down to a three-person crew after the early return, putting spacewalk plans on hold
Late Wednesday, a SpaceX Dragon capsule carrying four astronauts undocked from the International Space Station, marking NASA’s first medical evacuation from the orbiting lab following a crew member’s health issue.
The decision trims the Crew-11 mission by about a month, leaving the station with fewer crew members until the next rotation. It’s a real-time challenge for NASA and its partners to see how fast they can get astronauts back when a health issue arises in orbit.
NASA hasn’t disclosed which astronaut is involved or the nature of the condition, citing medical privacy. The agency emphasized the situation isn’t an emergency and confirmed the crew member remains stable.
“Our timing of this departure is unexpected,” NASA astronaut Zena Cardman said ahead of the trip home. NASA commentator Rob Navias confirmed the affected crew member “was and continues to be in stable condition.” Outgoing station commander Mike Fincke posted on social media: “First and foremost, we are all OK.” 1
NASA announced live coverage will pick back up at 2:15 a.m. EST, ahead of a planned deorbit burn—a short engine firing to bring the capsule down from orbit—scheduled for 2:51 a.m. Splashdown is expected around 3:41 a.m. EST off California’s coast. A post-landing briefing led by NASA Administrator Jared Isaacman will stream at 5:45 a.m. on NASA+, Amazon Prime, and YouTube. 2
Crew-11 features NASA astronauts Cardman and Fincke, alongside Japan Aerospace Exploration Agency’s Kimiya Yui and Russia’s Oleg Platonov. They reached the station in early August, with plans to remain until mid-February.
James Polk, NASA’s chief health and medical officer, pointed to a “lingering risk” and unresolved questions around the diagnosis as reasons for the early return. The agency canceled a planned spacewalk last week, an excursion to install hardware outside the station, after the medical concern surfaced.
After Crew-11 leaves, three astronauts will stay aboard the ISS: NASA’s Christopher Williams and Russian cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, according to NASA and mission updates. NASA announced it will pause routine spacewalks until a new crew arrives, since such operations need two suited astronauts plus extra support from those inside the station.
The episode highlights NASA’s heavy reliance on SpaceX’s Dragon for U.S. crew flights to and from the ISS, while Russia’s Soyuz continues to serve as a backup for its cosmonauts, including occasional seat swaps between the agencies. Boeing, tasked with building a rival U.S. crew capsule, has encountered delays that disrupted NASA’s crew rotation plans over the past year, the Associated Press reported. “The health and the well-being of our astronauts is always and will be our highest priority,” Isaacman said in last week’s announcement, according to AP. 3
Much remains uncertain. NASA says splashdown timing and location hinge on weather, sea conditions, and how ready the recovery team is. It hasn’t detailed the medical issue, labeling it only as a concern, leaving outside experts to speculate on the potential risks if the condition deteriorates before recovery.
