NASA Cut SpaceX Crew-11 1 Month Short After Mike Fincke's 20-Minute Medical Event

Eight days after Mike Fincke suddenly lost the ability to speak for 20 minutes in January, NASA brought SpaceX Crew-11 home a month early, the first health-related early ISS return among more than 290 station visitors.
NASA called it a serious medical condition but disclosed no diagnosis; Fincke said the episode was likely space-related, and the crew used the ISS ultrasound system with mission-control support to assess him.
Microgravity-driven fluid shifts can disrupt blood flow and may trigger problems such as transient speech lapses, experts said; a 2019 study of 11 astronauts found six had stagnant or reversed blood flow and one had a blood clot.
The case is sharpening planning for longer missions, where crews cannot quickly return and may face communication delays of 40 minutes near the moon and roughly 40 minutes round-trip from Mars.

Overview
On January 7, 2026, astronaut Mike Fincke experienced a sudden medical incident aboard the International Space Station, which led to the first-ever early medical return for a NASA mission. The swift and decisive actions of his crewmates, guided by NASA’s flight surgeons, stabilized his condition. After a thorough evaluation, NASA decided to bring Crew-11 back to Earth ahead of schedule, since advanced medical imaging was not available on the space station. This unprecedented event highlighted the importance of crew training, robust protocols, and the need for better onboard medical capabilities for future space missions.
