Hubble Space Telescope Hubble Space Telescope The Hubble Space Telescope (HST) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. Although not the first space telescope, Hubble is one of the largest and most versatile and is well known as both a vital research tool and a public relations boon for astronomy. The HST is named after the astronomer Edwin Hubble and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory and the Spitzer Space Telescope. With a mirror, Hubble's four main instruments observe in the near
Space Shuttle Columbia disaster orbiter prevented safe reentry. The shuttle's main fuel tank is covered in thermal insulation foam intended to prevent ice from forming when the tank is full of liquid hydrogen and oxygen. Such ice could damage the shuttle if shed during lift-off. Mission STS-107 was the 113th Space Shuttle launch. Planned to begin on January 11, 2001, the mission was delayed 18 times and eventually launched on January 16, 2003, following STS-113. (The Columbia Accident Investigation Board determined that this delay had nothing to do with the catastrophic failure.) 81.7 seconds after launch from Kennedy Space Center's LC-39-A, a suitcase-sized piece
