![]() Scientists work to retrieve Galileo's Io flyby data NASA/JPL NEWS RELEASE Posted: August 14, 2001
On Saturday the spacecraft again uses its thrusters, this time to turn in place and point the antenna closer to the Earth. This 4 degree turn takes about 10 minutes to perform. On Sunday, routine maintenance of the propulsion system is performed. This will guarantee that all parts of the propulsion system are properly exercised, not just those branches that are used for the particular maneuvers and turns we have done recently. In addition to these navigation and engineering tasks, playback of the
science data from last weekend's flyby continues. A quick survey of the
data on the tape takes up the first week or so of playback. Due to the
effects of the accumulated radiation the spacecraft has received in its
nearly six years in orbit around Jupiter, measurements from several
instruments have been affected. The survey will determine if any of the
data on the tape are bad, and allow the scientists to plan how best to
retrieve the good data on subsequent passes over the tape.
