MARS OBSERVER STATUS REPORT
January 20, 1993
9:00 AM PST
Flight Sequence C6 B became active at 11:58 AM on January 18.
Magnetometer/Electron Reflectometer, Gamma Ray Spectrometer, and
Mars Observer Camera were powered on for instrument calibration
activities. The MOC test continues through noon Monday, January 25, while
MAG/ER (Magnetometer/Electron Reflectometer) and GRS (Gamma Ray Spectrometer)
calibrations continue beyond that date. The MOC PI (Principal Investigator)
reports that the instrument is performing as expected, but will not have
image information available until sufficient analysis has been performed.
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.
Efforts to receive Ka band telemetry last week were successful.
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 at the 2k engineering rate during
periods of minimal activity, the 4k Science and Engineering rate during
instrument calibration activities, and at 16K during DTR playback.
Today the spacecraft is 58,313,994 km (36,234,636 miles) from Earth,
traveling at a velocity of 12.9012 kilometers per second (28,859 miles
per hour) with respect to Earth. One way light time is approximately 195
seconds.
