    Instrument Description
    ======================
      The Radio Science Subsystem (RSS) was used to support the radio
      science investigation.  This investigation utilizes the radio
      signals to and from the spacecraft to obtain a variety of
      information.  Transponders on the spacecraft send back signals
      that are coherent with those received from earth so that
      precision Doppler and ranging measurements can be made.  The
      downlinks from the spacecraft include two coherent frequencies
      (S band and X band) so that dispersion in the interplanetary
      medium can be measured and corrected for.
 
 
    Science Objectives
    ==================
      From analysis of the radio signals a surprising diversity of
      informatin can potentially be obtained and the Radio Science
      Team has identified a large number of scientific objectives,
      which fall into three categories: dynamical, surface, and
      internal properties of Mars, atmospheric and ionospheric
      properties of Mars, and miscellaneuos solar system properties.
