Endeavour, the fifth and final space shuttle was created after the space shuttle program's greatest tragedy. Congress authorized NASA to replace the Space Shuttle Challenger, which was lost shortly after liftoff in 1986. NASA used spare parts from its shuttle fleet to create the new orbiter.
Endeavour flew into space 25 times. Among other career highlights, its crew members performed the first Hubble Space Telescope servicing mission. Endeavour also reached the Mir space station once and the International Space Station multiple times.
