Profile America -- Tuesday, April 26th. One of the greatest scientific achievements in history began this week 21 years ago -- when the crew of the space shuttle Discovery put the Hubble Space Telescope into orbit. The telescope was named for the great American astronomer Edwin Hubble. It has produced far more distant images than earth-bound instruments can achieve, and has largely rewritten our understanding of the universe and how it works. Between 1993 and 2009, the Hubble Telescope was serviced and upgraded five times by shuttle crews. From 2000 to 2009, the U.S. launched 54 noncommercial space vehicles, along with 24 commercial launches. You can find these and more facts about America from the U.S. Census Bureau, online at www.census.gov.
