Space medical mystery: astronaut's sudden speech loss on ISS unresolved
NASA is investigating a mid-January medical episode in which Pittsburgh astronaut Mike Fincke suddenly couldn't speak aboard the International Space Station; doctors ruled out a heart attack, but the exact cause remains unknown after ultrasound tests and extensive medical reviews, prompting an early return for Fincke and the canceled spacewalk for crewmates—though Fincke says he feels fine and hopes to fly again one day.
