NASA Examines Technology Demonstration to Raise Swift Space Telescope Orbit

  • One response
The telescope, which has been in space for over 20 years, could burn up in the atmosphere if its orbit is not raised. * Design studies are examining an orbit raise that could extend the Swift Space Telescope's operation and advance satellite servicing capabilities.
