                        MARS OBSERVER STATUS REPORT
                             January 8, 1993
                               1:30 PM PST

The spacecraft is in Array Normal Spin and continues to perform as
expected. Teams are continuing to study the Attitude Control Subsystem
miscompared star problem.

Downlink is via the HGA (High Gain Antenna) at 2 kilobits per second.
Uplink is at 125 bps using the LGA (Low Gain Antenna). HGA calibration
activities were completed last evening.  Those calibrations indicate
HGA performance to be nominal.

With completion of C5 B as scheduled at 7:00 PM last evening, no flight
sequences are currently active.  This is to provide a ten day window to
allow upload of a new Flight Software build.

Teams are preparing Flight Software Build 7.1.1 for uplink on January 13
though 15.  Build 7.1.1 contains changes to AACS (Attitude and Articulation
Control Subsystem) Fault Protection logic determined to be necessary by
the Spacecraft Team.  These changes are not related to the Celestial
Sensor Assembly miscompared star situation.

The next Flight Sequence, C6 B (necessary C6 A activities were moved
into C5 B) is scheduled to go active on January 18.

Ka Band Link Experiment (KaBLE) activities have begun and are scheduled
to take place daily through January 12.  There are additional KaBLE
opportunities projected for January 16 and 17.
