                       MARS OBSERVER STATUS REPORT
                           January 22, 1993
                             10:00 AM PST

Flight Sequence C6 B is active.  Magnetometer/Electron Reflectometer,
Gamma Ray Spectrometer, and Mars Observer Camera (MOC) instrument
calibration activities continue.

Digital Tape Recorders 1 and 3 will be played back on January 26 and 27.
DTRs 1 and 3 contain the Geotail measurement data collected in December.

The Spacecraft Team reports that the spacecraft is performing nominally
in Array Normal Spin.  Uplink and downlink are via the HGA (High Gain
Antenna); uplink is at 125 bps; the downlink rate is being varied among
2k engineering, 4k Science and Engineering, and 16K for MOC Focus Test
activities.

On Wednesday morning, the Thermal Emissions Spectrometer Principal
Investigator (P. Christensen of ASU) presented an overview of TES
including scientific objectives, instrument sub-sections, and a summary
of instrument commanding to Mission Operations System team members.
Dr. Christensen also discussed the TES Team's rationale for proposed
instrument calibrations at some point within 10 to 20 days prior to Mars
Orbit Insertion.

Next week, flight sequence C7 will be updated with final TCM-2
(Trajectory Corretion Maneuver #2) parameters as developed by the Navigation
and Spacecraft teams.  TCM-2 will provide a velocity change of approximately
10 meters/second.  Uplink of C7 is scheduled for February 6 with sequence
activation and the maneuver to take place on February 8.
