CAPE CANAVERAL, Fla. (AP) – The astronaut who prompted NASA's first medical evacuation earlier this year has said that doctors still don't know why he suddenly fell sick at the International Space Station. Four-time space flier Mike Fincke said he was eating dinner on January 7 after prepping for a spacewalk the next day when it happened. He couldn't talk, and he remembers no pain, but his anxious crewmates jumped into action after seeing him in distress and requested help from flight surgeons
