- MARS OBSERVER STATUS REPORT
- January 28, 1993
- 8:30 AM PST
-
- Flight Sequence C6 B is active. Magnetometer/Electron Reflectometer and
- Gamma Ray Spectrometer are taking data.
-
- 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; downlink is at the 4 kilobits/second
- Science and Engineering data rate.
-
- Playback of DTRs (Digital Tape Recorders) 1 and 3 completed yesterday.
- An initial problem flowing data at the 85 Kilobit playback rate due to
- ground configuration was experienced Tuesday but was resolved quickly.
- No data was lost. DTRs 1 and 2 contained the Geotail measurement data
- collected in December.
-
- Flight Engineering Office teams are investigating an apparent
- dissimilarity between on-board Standard Control Processor spacecraft
- state indications. The control SCP shows the expected state, while the
- backup SCP indicates the spacecraft to be in Contingency mode. There is
- no present danger or risk to the spacecraft. A memory readout of the
- COMPOOL area of SCP2 will be performed today, and compared to
- telemetry being received from SCP1.
-
- Flight sequence C7 is being updated with final TCM-2 (Trajectory Correction
- 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.
