  Title: Artist concept of Magellan spacecraft orbiting Venus
  Description:
  Magellan spacecraft orbits Venus in this artist concept.  The continued
  quest  for detailed topographic measurements of Venus will again be
  undertaken in  April 1989 by Magellan, named after the 16th century
  Portuguese explorer.   Magellan will orbit Venus about once every three
  hours, acquiring radar data  for 37 minutes of each orbit when it is
  closest to the surface.  Using an  advanced instrument called a synthetic
  aperature radar (SAR), it will map  more than 90 per cent of the surface
  with resolution ten times better than  the best prior spacecraft.  Magellan
  is managed by the Jet Propulsion  Laboratory (JPL); Martin Marietta is
  developing the spacecraft and Hughes  Aircraft Company, the advanced
  imaging radar. Magellan will be deployed from  the payload bay (PLB) of
  Atlantis, Orbiter Vehicle (OV) 104, during mission  STS-30.
