Michael Foale

Colin Michael Foale is a British-American astrophysicist and former NASA astronaut. He is a veteran of six space missions, and is the only NASA astronaut to have flown extended missions aboard both Mir and the International Space Station. He was the second Briton in space and the first to perform a space walk. Until 17 April 2008 he held the record for most time spent in space by a US citizen: 374 days, 11 hours, 19 minutes, and he still holds the cumulative-time-in-space record for a UK citizen.
