Space telescope Hubble Space Telescope, which was launched on April 24, 1990 by the Space Shuttle "Discovery" (STS-31). Performing astronomy from ground-based observatories on Earth is limited by the filtering and distortion of electromagnetic radiation (scintillation or twinkling) due to the atmosphere. Some terrestrial telescopes can reduce atmospheric effects with adaptive optics. A telescope orbiting Earth outside the atmosphere is subject neither to twinkling nor to light pollution from artificial light sources on Earth. As a result, the angular resolution of space telescopes is often much smaller than a ground-based telescope with a similar aperture. Space-based astronomy is even more important for
Space Shuttle Endeavour several ceremonies in Washington, D.C., including a White House ceremony where then-President George H. W. Bush presented awards to each school. "Endeavour" was delivered by Rockwell International Space Transportation Systems Division in May 1991 and first launched a year later, in May 1992, on STS-49. Rockwell International claimed that it had made no profit on Space Shuttle "Endeavour", despite construction costing US$2.2 billion. On its first mission, it captured and redeployed the stranded "INTELSAT VI" communications satellite. The first African-American woman astronaut, Mae Jemison, was launched into space on the mission STS-47 on September 12, 1992. "Endeavour" flew the first
