Shuttle Orbiter Endeavour (NASA Orbiter Vehicle Designation: OV-105) is the fifth and most recent NASA space shuttle to be built.

Construction of Endeavour began in 1987 to replace Challenger, which was lost in an accident in 1986. Structural spares from the construction of shuttles Discovery and Atlantis were used in its assembly.

Endeavour was first launched in 1992 and on its first mission captured and redeployed a stranded communications satellite. In 1993 it made the first service mission to the Hubble Space Telescope. Endeavour was withdrawn from service for eight months in 1997 for a retrofit, including installation of a new airlock. In December 1998, it delivered the Unity Module to the International Space Station.

The orbiter is named after the HM Bark Endeavour, the ship commanded by 18th century explorer James Cook (which explains the British spelling).
