The 2-day journey piloted by John Younger and Robert Crippen demonstrated the launch and return capabilities of the shuttles.
Over the course of 30 years, the area shuttles – Columbia, Challenger, Discovery, Atlantis, and Endeavour – launched and serviced satellites and observatories together with the Hubble House Telescope, had been a key a part of constructing the Worldwide House Station, and served as a labs for a variety scientific analysis in orbit. In all, 355 astronauts flew on the area shuttles. This system’s triumphs had been marred by tragedy, although, when Challenger’s rocket exploded 73 seconds after liftoff in 1986, and Columbia broke up on reentry in 2003. Following the Columbia catastrophe, the shuttle program’s denouement was deliberate, and it ended on July 21, 2011, when Atlantis landed after finishing STS-135.
