NASA astronaut who suffered serious medical issue on ISS steps forward

The identity of the astronaut had been kept secret up until now.

The NASA astronaut whose serious medical issue prompted the early return of SpaceX’s Crew-11 from the International Space Station (ISS) has spoken out about the incident.

In a statement posted on NASA’s website on Wednesday, NASA astronaut Mike Fincke stepped forward to say that while in orbit aboard the ISS, he experienced a medical event “that required immediate attention from my incredible crewmates,” adding that “thanks to their quick response and the guidance of our NASA flight surgeons, my status quickly stabilized.”

Fincke, 58, continued: “After further evaluation, NASA determined the safest course was an early return for Crew-11 — not an emergency, but a carefully coordinated plan to be able to take advantage of advanced medical imaging not available on the space station.”

Crew-11 arrived at the ISS in August 2025 and weren’t due to return until at least a month later. But it became apparent that all was not well aboard the orbital outpost on January 7 when NASA called off a spacewalk involving Fincke and colleague Zena Cardman that was scheduled for the following day.

In his statement, Fincke declined to give any details about the nature of his medical condition, but at the time the situation was deemed serious enough for newly installed NASA administrator Jared Isaacman to bring the four-person crew home early aboard their SpaceX Dragon spacecraft, which splashed down off the coast of San Diego on January 15.

“I am deeply grateful to my fellow Expedition 74 members — Zena Cardman, Kimiya Yui, Oleg Platonov, Chris Williams, Sergey Kud-Sverchkov, and Sergei Mikayev — as well as the entire NASA team, SpaceX, and the medical professionals at Scripps Memorial Hospital La Jolla near San Diego,” Fincke said in his statement. “Their professionalism and dedication ensured a positive outcome.”

He added that he’s “doing very well and continuing standard post-flight reconditioning at NASA’s Johnson Space Center in Houston,” describing spaceflight as “an incredible privilege,” and how it sometimes “reminds us just how human we are.”

Crewed space missions have, very occasionally, been shortened due to technical issues, but the rescheduling of Crew-11 marks the first time in NASA’s history that an astronaut mission has been cut short over health concerns.

While the ISS has various medical facilities to cope with health emergencies, in this case it was clear that the safest way forward was to bring the crew home.

Dimming the sun sounds unhinged, but this new study on El Niño makes a surprisingly good case for it
A natural test case, Australia's worst-ever wildfire season, suggests the idea deserves serious consideration.
Nature, Outdoors, Sky

When I first saw "scientists propose dimming the sun," I rolled my eyes. It sounds like a science fiction movie cooked up after watching many climate documentaries. But a new study, published on July 8, 2026, in the journal Science Advances, seems to have a genuinely compelling argument.

A Super El Niño is currently forming in the Pacific, feared to be the most intense in decades. It could escalate floods, wildfires, and extreme heat events worldwide. However, Researchers at UC San Diego's Scripps Institution of Oceanography, led by climate scientists Kate Ricke and Jessica Wan, are now proposing one of the most interesting solutions I’ve come across.

Scientists warn Elon Musk’s orbital data centers could blind Earth’s biggest telescopes
A new ESO study suggests millions of satellites could make parts of the night sky effectively unusable for astronomy.

The race to blanket Earth with satellite internet has unlocked faster connectivity for millions. But according to the European Southern Observatory (ESO), it could also make one of humanity's oldest hobbies, and one of its most important sciences, a whole lot harder. The organization warns that the rapid growth of satellite mega-constellations could severely disrupt observations made by some of the world's most powerful telescopes.
