Space shuttle Endeavour makes its final landing at NASA's Kennedy Space Center in Florida on June 1, 2011 to end the STS-134 mission, the shuttle's final spaceflight and NASA's second-to-last shuttle mission.

The space shuttle Endeavour has capped a storied career with one final mission before it retires, leaving behind a 19-year legacy of flying in space.
Endeavour is NASA's youngest orbiter, built as a replacement for the shuttle Challenger, which was destroyed along with its crew in 1986.
The orbiter launched six astronauts into space on May 16 from NASA's Kennedy Space Center and returned to Earth in the wee hours of June 1. This final misison, STS-134, delivered a $2 billion particle detector called the Alpha Magnetic Spectrometer to the International Space Station, along with a set of backup supplies to outfit the station.

After this final voyage, Endeavour will be retired to the California Science Museum in Los Angeles for public display.
Here's a by-the-numbers look at Endeavour's lasting legacy in space:
122,883,151: The total miles Endeavour has traveled after its last voyage. [Video: Shuttle Endeavour Lands After Final Voyage]
500,000: The number of spectators estimated to turn out to Florida's Space Coast to watch Endeavour's final launch.
6,154: The number of entries in a national student contest to name the space shuttle Endeavourwhen it was built. The name Endeavour honors the 17th century sailing ship HMB Endeavour, which was captained by British seaman James Cook on a famous voyage of exploration in the South Pacific.
17,400: The speed at which Endeavour traveled (in miles per hour) to remain in orbit. It's about Mach 25, or five times the speed of a bullet.
4,671: The number of orbits Endeavour made of Earth during all of its missions.
1992: The year Endeavour lifted off on its first flight. The orbiter carried seven astronauts to space on the STS-49 mission to rescue and repair a broken communications satellite.
299: The total number of days Endeavour has spent in space, counting those during this final flight STS-134.
133: The number of crew members Endeavour has carried to orbit, not including the six astronautsslated to ride the shuttle on the STS-134 mission.
25: The number of missions Endeavour will have flown by the time it is retired.
12: The number of times Endeavour will have visited the International Space Station before it is retired. The shuttle's trips to the orbiting laboratory include the very first U.S. space station mission, the STS-88 flight in December 1998 that launched the first American space station module, Unity.

3.5: The number of years it took NASA to build Endeavour. Construction on the orbiter began in September 1987, and completed in April 1991.
1: The number of times Endeavour has visited the Hubble Telescope in orbit. The shuttle was used to launch the first Hubble servicing mission, STS-61 in December 1993, which famously corrected the observatory's faulty optics.
