Space Shuttle Orbiter Endeavour (NASA Orbiter Vehicle Designation: OV-105), is the fifth and final operational NASA space shuttle.

History
Endeavour features new hardware designed to improve and expand orbiter capabilities. Most of this equipment was later incorporated into the other three orbiters during out-of-service major inspection and modification programs. Endeavour's upgrades include:
Modifications resulting from a 2005-2006 refit of Endeavour include:

A 40-foot diameter drag chute that is expected to reduce the orbiter's rollout distance by 1,000 to 2,000 feet.
The plumbing and electrical connections needed for Extended Duration Orbiter (EDO) modifications to allow up to 28-day missions (although a 28-day mission has never yet been attempted; the current record is 17 days, which was set with the Columbia orbiter).
Updated avionics systems that include advanced general purpose computers, improved inertial measurement units and tactical air navigation systems, enhanced master events controllers and multiplexer-demultiplexers, a solid-state star tracker and improved nose wheel steering mechanisms.
An improved version of the Auxiliary Power Units (APUs) that provide power to operate the Shuttle's hydraulic systems.
The Station-to-Shuttle Power Transfer System (SSPTS), which converts 8 kilowatts of DC power from the ISS main voltage of 120VDC to the orbiter bus voltage of 28VDC. This upgrade will allow Endeavour to remain on-orbit while docked at ISS for an additional 3- to 4-day duration. The corresponding power equipment was added to the ISS during the STS-116 station assembly mission, and Endeavour will first fly with SSPTS capability during planned STS-118. Upgrades and features
Space Shuttle Endeavour has flown 19 flights, spent 206.60 days in space, completed 3,259 orbits, and flown 85,072,077 miles (136,910,237 km) in total, as of February 2003. It last flew in November 2002.
