Flights of discovery

Flights
Space Shuttle Discovery has flown 33 flights, spent 241.95 days in space, completed 3,808 orbits, and flown 98,710,673 statute miles (158,859,429 km) in total, as of December 2006. It has flown the most flights of all Space Shuttles so far (a title it is likely to keep). Discovery has also flown on more individual flights than any other spacecraft in history and is likely to retain this honor for some time as no planned launch vehicles (neither American nor International) have a designed lifespan of more than 10 flights. Discovery has flown both "return to flight" missions after the Space Shuttle Challenger and Columbia disasters: STS-26 in 1988 and STS-114 in 2005.
