In a series of complex operations involving multiple spacewalks, Endeavour's astronaut crew swapped out some of Hubble's optics and other gear. In 1993, Endeavour launched on its STS-61 flight - the first Hubble servicing mission - to fix the problem. Shortly after NASA's Hubble Space Telescope launched in 1990, scientists noticed that the instrument's images were a bit blurry. It helped save the Hubble Space Telescope This recycling ethic helped keep Endeavour's construction costs down to $1.7 billion, according to NASA officials.Ĥ.

These pieces were left over from the construction of the shuttles Discovery and Atlantis. While Endeavour debuted a fair amount of new gear - it was the first shuttle to use a drag parachute during landing, for example, and it featured advanced avionics systems - much of the orbiter was built from spare parts. Endeavour was built on the cheap - sort of 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).ģ.

Bush announced the winning name in May 1989. The kids were given some guidance - the name had to be based on a historic oceangoing research or exploration vessel. In 1988, NASA staged a national competition among elementary and secondary school students to hang a name on the new shuttle. Friday's launch will initiate Endeavour's 25th space mission.Įndeavour is the only shuttle to have been named by children. Congress authorized the construction of Endeavour - NASA's fifth spacegoing shuttle - in 1987, and the orbiter first blasted off in 1992.
