NASA Begins Medical Evacuation for SpaceX Crew-11 Mission
NASA has announced the start of a controlled medical evacuation for the four-member SpaceX Crew-11 mission currently aboard the International Space Station (ISS). This decision was made due to a serious but stable medical issue affecting one crew member, whose identity remains confidential.
As a result, their mission will conclude about a month earlier than scheduled, originally expected to end in late February 2026 after transitioning duties to Crew-12. The astronauts are set to return to Earth shortly using their Crew Dragon spacecraft.
During a press conference, NASA Administrator Jared Isaacman shared, “Yesterday, Jan. 7, a single crew member on board the station experienced a medical situation and is now stable. After discussions with Chief Health and Medical Officer, Dr. JD Polk, and leadership across the agency, I’ve come to the decision that it’s in the best interest of our astronauts to return Crew-11 ahead of their planned departure.”
The Crew-11 team includes American Mission Commander Zena Cardman, Pilot Mike Fincke, JAXA astronaut Kimiya Yui from Japan, and Roscosmos cosmonaut Oleg Platonov from Russia. They will be returning via the SpaceX Dragon Endeavor spacecraft soon.
“Since the astronaut is stable, this isn’t an emergency evacuation; we’re not rushing to get them down. However, the uncertainty surrounding their diagnosis poses some risk,” stated Dr. James “JD” Polk. “We are prioritizing caution for the crew member’s well-being,” he added.
Polk pointed out that this marks the first medical evacuation in the 25 years humans have lived on the ISS. To protect privacy, NASA is not disclosing the name or specifics regarding the affected astronaut’s condition.
Earlier this week, NASA also postponed a planned spacewalk for the two American astronauts, originally scheduled for Thursday. Polk clarified that the medical issue is not related to the spacewalk, which was chiefly impacted by the challenges of working in microgravity.
In past instances, U.S. astronaut Mark Vande Hei had a planned spacewalk canceled in 2021 due to a pinched nerve, while another was called off in 2024 due to discomfort in the spacesuit.
With the Crew-11 departure, only NASA’s medical physicist Christopher Williams and Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikayev will remain on the ISS.
The Crew-11 astronauts reached the ISS on August 1, 2025, with an initial plan to leave in February after Crew-12 arrives via SpaceX Dragon.
Although Crew-12’s launch is scheduled for no earlier than February 15, Isaacman reassured that any changes to that timeline will not impact the Artemis II lunar mission, as the two missions operate independently.
Artemis II will mark the Orion spacecraft’s first crewed flight, with four astronauts orbiting the Moon to test essential technology for future deep space exploration.
