This led to it being 1,000 kilograms (2,200 pounds) lighter than Columbia, though still 2,600 kilograms (5,700 pounds) heavier than Discovery.ĭuring its three years of operation, Challenger was flown on ten missions in the Space Shuttle program, spending over 62 days in space and completing almost 1,000 orbits around Earth. Lessons learned from the first orbital flights of Columbia led to Challenger 's design possessing fewer thermal protection system tiles and a lighter fuselage and wings. However, after NASA found that their original plan to upgrade Enterprise for spaceflight would be more expensive than upgrading Challenger, the orbiter was pressed into operational service in the Space Shuttle program. Initially manufactured as a test article not intended for spaceflight, it was utilized for ground testing of the Space Shuttle orbiter's structural design. It was destroyed in January 1986 soon after launch in an accident that killed all seven crewmembers aboard. ![]() Named after the commanding ship of a nineteenth-century scientific expedition that traveled the world, Challenger was the second Space Shuttle orbiter to fly into space after Columbia, and launched on its maiden flight in April 1983.
