Over the course of its 19-year spaceflight career, Endeavour logged nearly 123 million miles (198 million kilometers) and zipped around the Earth more than 4,600 times. Here are some other interesting facts about the orbiter.
FIRST STOP: It's NASA's Baby
Congress authorized the construction of Endeavour — NASA's fifth spacegoing shuttle — in 1987, and the orbiter first blasted off in 1992. Endeavour flew a total of 25 space missions, with the final one launching in May 2011.
NEXT: Named By Kids
Then-president George H.W. Bush announced the winning name in May 1989. The shuttle's namesake, H.M.S. Endeavour, was commanded by Britain's James Cook on his epic 18th-century voyage of discovery in the South Pacific (hence the orbiter's British spelling).
NEXT: Built from Spare Parts
These pieces were left over from the construction of the shuttles Discovery and Atlantis. This recycling ethic helped keep Endeavour's construction costs down to $1.7 billion, according to NASA officials.
NEXT: Hubble Space Telescope Hero
In a series of complex operations involving multiple spacewalks, Endeavour's astronaut crew swapped out some of Hubble's optics and other gear. Soon the telescope was seeing the universe in crisp, sharp detail.
"Without that mission, Hubble would be rather useless in orbit," said space-history expert Robert Pearlman, editor of collectSPACE.com (which is a SPACE.com partner). Endeavour, he added, "more or less saved Hubble and helped give it the legacy it has today."
NEXT: Helped Create Space Station
"By attaching Unity, it became a space station, and an international one at that," Pearlman told SPACE.com.
On its final STS-134 mission, Endeavour made another significant contribution to the ISS, delivering the final big piece yet to be added to the station from the American side — the $1.5 billion Alpha Magnetic Spectrometer physics experiment.
"Endeavour sort of bookends the International Space Station assembly," Pearlman said.
