The crew of the U.S. space shuttle Discovery places the Hubble
Space Telescope, a long-term space-based observatory, into a
low orbit around Earth.
The space telescope, conceived in the 1940s, designed in the
1970s, and built in the 1980s, was designed to give
astronomers an unparalleled view of the solar system, the
galaxy, and the universe. Initially, Hubbleâ€Ös operators
suffered a setback when a lens aberration was discovered,
but a repair mission by space-walking astronauts in
December 1993 successfully fixed the problem, and Hubble
began sending back its first breathtaking images of the universe.
Free of atmospheric distortions, Hubble has a resolution
10 times that of ground-based observatories. About the
size of a bus, the telescope is solar-powered and orbits
Earth once every 97 minutes. Among its many astronomical
achievements, Hubble has been used to record a cometâ€Ös
collision with Jupiter, provide a direct look at the
surface of Pluto, view distant galaxies, gas clouds and
black holes, and see billions of years into the universeâ€Ös past.
