“It was completely unexpected”: NASA astronaut talks about his medical scare and says it remains a mystery

The astronaut who caused NASA’s first medical evacuation earlier this year said Friday that doctors still don’t know why he suddenly fell ill on the International Space Station.

Mike Finckewho has flown in space four times, says he was having dinner on Jan. 7 after preparing for a spacewalk the next day when it happened. He couldn’t speak and couldn’t remember any pain, but his anxious crewmates sprang into action when they saw him in distress and called the flight surgeons on the ground for help.

“It was completely unexpected. It was incredibly fast,” he said in an interview with The Associated Press from the Johnson Space Center in Houston.

Fincke, 59, a retired Air Force colonel, said the episode lasted about 20 minutes and he felt fine afterward. He said he still feels that way. I had never experienced anything like it, before or since.
