During the 16-day mission, Endeavour and its crew will deliver the Alpha Magnetic Spectrometer (AMS) and spare parts including two S-band communications antennas, a high-pressure gas tank and additional spare parts for Dextre.
The flight is Endeavour's 25th since a maiden voyage in 1992. The youngest shuttle orbiter was built as a replacement for Challenger, the shuttle destroyed in a 1986 launch accident that killed seven astronauts. Endeavour has traveled 116,372,930 miles, spent 283 days in space and has had a total of 4,423 orbits since its first mission. After returning to earth in 16 days time Endeavour will be retired to a Los Angeles museum.
