The Hubble Space Telescope


 

Hubble was originally designed in the 1970s and launched in 1990. Thanks to on-orbit service calls by the Space Shuttle astronauts, Hubble continues to be a state-of-the-art, model year 2001 space telescope.

Hubble orbits 600 kilometers (375 miles) above Earth, working around the clock to unlock the secrets of the Universe. It uses excellent pointing precision, powerful optics, and state-of-the-art instruments to provide stunning views of the Universe that cannot be made using ground-based telescopes or other satellites.

As of March 2000, Hubble has:

  • Taken more than 330,000 separate observations.
  • Observed more than 25,000 astronomical targets.
  • Created a data archive of over 7.3 terabytes. (That is like completely filling a PC every day for 10 years.)
  • Provided data for more than 2,663 scientific papers.
  • Traveled about 1.489 billion miles—nearly the distance from Earth to Uranus. It circles the Earth about every 97 minutes.
  • Received more than 93 hours of on-orbit improvements in three successful servicing missions.
