The Nasa space shuttle has been launched 135 times, carrying 355 astronauts a total of 870 million kilometres. The first launch of the space shuttle was on April 12, 1981, with the launch of space shuttle Columbia. Four other shuttles – Challenger, Discovery, Atlantis and Endeavour – were made.
For the first time, NASA has released high-definition video taken during the retrieval of solid rocket booster segments from the Atlantic Ocean. The solid rocket boosters provided 144 million horsepower of thrust for the final launch of space shuttle Discovery on its STS-133 mission.
