    Instrument Overview
    ===================
      The Mariner 9 (MR9) Radio Science investigations
      utilized instrumentation with elements on the spacecraft and
      at the NASA Deep Space Network (DSN).  Much of this was
      shared equipment, being used for routine telecommunications
      as well as for Radio Science.  The performance and
      calibration of both the spacecraft and tracking stations
      directly affected the radio science data accuracy, and they
      played a major role in determining the quality of the
      results.  The spacecraft part of the radio science
      instrument is described immediately below; that is followed
      by a description of the DSN (ground) part of the instrument.


    Instrument Specifications - Spacecraft
    ======================================
      The Mariner 9 spacecraft telecommunications
      subsystem served as part of a radio science subsystem for
      investigations of Mars.  Many details of the subsystem are
      unknown; its 'launch date' is known to be 1971-05-30.

    Instrument Overview - Spacecraft
    ================================
      The Doppler shift of the S-band telemetry signal during
      occultation of the spacecraft by Mars provided the vertical
      distribution of the index of refraction of the Martian
      atmosphere. These data yield the vertical distribution of
      neutral and ionized species."
