- MARS OBSERVER STATUS REPORT
- December 29, 1992
- 8:30 AM PST
- Launch +95 Days
-
- The Spacecraft Team reports that spacecraft subsystems and
- instruments are performing nominally. The spacecraft is in Array
- Normal Spin; the downlink data rate is at 250 bps while the
- uplink data rate is 125 bps.
-
- C5 continues executing as expected.
-
- Yesterday's status update reported that Mission Operations is
- planning to send interactive commands to power on an power off
- subsystem heaters this week to dissipate excessive power build
- up. It inaccurately attributed that excess power to the length of
- time spent in Sun Comm Power while teams prepared to recover from
- the loss of inertial reference.
-
- Further information from the Spacecraft Team indicates that the
- power build up is not due to that reason, but instead, to greater
- than expected solar array efficiency in producing power. Power
- subsystem and Spacecraft Team engineers were better able to
- analyze performance through refinement of subsystem power models
- and information received from flight up to this point.
-
- Today the spacecraft is 37,533,188 km (23,322,041 miles) from
- Earth, travelling at a velocity of 9.2476 km per second (20,686
- mph) with respect to Earth. One way light time is approximately
- 125 seconds.
