Colin Michael Foale, CBE, PhD, (born 6 January 1957) is an Anglo-American astrophysicist and a NASA astronaut. He is a veteran of six space shuttle missions and extended stays on both Mir and the International Space Station. He was the first Briton to perform a space walk, and holds the record for most time spent in space by a UK and US citizen: 374 days, 11 hours, 19 minutes.
Foale joined the mission operations division of NASA in 1983 aged 24, working on the shuttles navigation system. Having gained dual-UK/US citizenship, he applied and was turned down twice as an astronaut candidate. After the Space Shuttle Challenger disaster in January 1986, Foale changed his application essay from writing about his dreams to focusing on the realities of leadership faced by NASA, and was selected in 1987.
In 1999, Foale was a member of space shuttle mission STS-103, during which he conducted an 8-hour spacewalk to replace components of the Hubble Space Telescope. In 2003, Foale was named commander of International Space Station Expedition 8 with cosmonaut Aleksandr Kaleri. His six-month tour of duty on the station ended on April 29, 2004. Foale is currently Deputy Associate Administrator for Exploration Operations at NASA HQ, Washington D.C.
