Space Shuttle Endeavour (Orbiter Vehicle Designation: OV-105) is one of the three currently operational orbiters in the Space Shuttle fleet of NASA, the space agency of the United States.[1] (The other two are Discovery and Atlantis.) Endeavour was the fifth and final NASA space shuttle to be built.

Endeavour is currently at Edwards Air Force Base in California. It landed on November 30, 2008 after completing its latest mission STS-126 to the International Space Station, which launched on November 14. Two scheduled landings at Kennedy Space Center were waved off due to poor weather conditions. Endeavour is scheduled be transported to Kennedy Space Center atop NASA's Shuttle Carrier Aircraft beginning December 7.
The United States Congress authorized the construction of Endeavour in 1987 to replace Challenger, which was lost in an accident in 1986. Structural spares from the construction of Discovery and Atlantis, two of the three remaining operating shuttles at the time, were used in its assembly. The decision to build Endeavour was favored over refitting Enterprise on cost grounds.
Endeavour was named through a national competition involving students in elementary and secondary schools. Entries included an essay about the name, the story behind it and why it was appropriate for a NASA shuttle, and the project that supported the name. Endeavour was the most popular entry, accounting for almost one-third of the state-level winners.[2] For example, Utah's state level winner, Nolan Butcher, a sixth grade student from Nibley Park Elementary school located in Salt Lake City Utah, selected Endeavour because some definitions of the word mean to be bold and put forth great effort. The national winners were Senatobia Middle School in Senatobia, Miss., in the elementary division and Tallulah Falls School in Tallulah Falls, Ga., in the upper school division. The national winners were selected based on the quality of the project submitted with their entries. They were honored at several ceremonies in Washington, D.C., including a White House ceremony where then-President George H.W. Bush presented awards to each school.[3]
The orbiter is named after HM Bark Endeavour, the ship commanded by 18th century explorer James Cook; the name also honored Endeavour, the Command Module of Apollo 15. This is why the name is spelled in the British English manner, rather than the American English spelling of "Endeavor." This has caused confusion, most notably when NASA themselves misspelled a sign on the launch pad in 2007.[4]
Endeavour was delivered by Rockwell International in May 1991 and first launched a year later, in May 1992, on STS-49. Rockwell International claimed that it had made no profit on Space Shuttle Endeavour, despite it costing $2.2 billion USD. On its first mission, it captured and redeployed the stranded INTELSAT VI 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. Endeavour completed its latest Orbiter Major Modification period, which began in December 2003, and ended on Thursday, October 6, 2005. During this time, the Orbiter received major hardware upgrades, including a new, multi-functional, electronic display system, often referred to as glass cockpit, and an advanced GPS receiver, along with safety upgrades recommended by the Columbia Accident Investigation Board (CAIB) for Shuttle return to flight after the disintegration of sister-ship Columbia during re-entry on February 1, 2003.
The STS-118 mission, the first for Endeavour following a lengthy refit, included astronaut Barbara Morgan, formerly assigned to the Educator Astronaut program, but now a full member of the Astronaut Corps, as part of the crew. Morgan was the backup for Christa McAuliffe on the ill-fated STS-51-L mission.
Endeavour features new hardware designed to improve and expand orbiter capabilities. Most of this equipment was later incorporated into the other two orbiters during out-of-service major inspection and modification programs. Endeavour's upgrades include:
Modifications resulting from a 2005-2006 refit of Endeavour include:
According to NASA, Space Shuttle Endeavour will be decommissioned in 2010, after 18 years of service, along with Discovery and Atlantis. NASA expects to have the Orion spacecraft ready no later than 2014. Based on the current (as of August 2007) consolidated launch manifest, Endeavour may be the last Orbiter to fly, contingent on the optional STS-133 mission to the International Space Station, which will carry the final components in the ISS assembly sequence, the EXPRESS Logistics Carrier ELC5 and ELC1, to orbit.
Space Shuttle Endeavour has flown 20 flights, spent 219.35 days in space, completed 3,259 orbits, and flown 85,072,077 miles (136,910,237 km) in total, as of August 2007[update].

NASA decided not to fix this damage in-flight as it was not believed to be serious enough to result in loss of vehicle or crew.
