- MAGELLAN STATUS REPORT
- January 11, 1993
-
- 1. The Magellan spacecraft continues to operate normally, orbiting
- Venus 50 times per week and transmitting a carrier signal (plus X-band
- telemetry) which is precisely tracked by the DSN (Deep Space Network)
- stations to extract gravity data.
-
- 2. Temperatures remain in the expected range. Bay 7 which contains
- the CDS (Command Data Subsystem), is at 46 degrees C with a cycle depth
- of 4 degrees. Transmitter B is at 49.2 degrees with a variation of 0.7
- degrees.
-
- 3. Attitude control continues to be precise. All starcals (star
- calibrations) over the weekend were successful with only one partial scan.
-
- 4. Magellan has completed 6523 orbits; 887 so far in Cycle-4 which
- will end on May 25, 1993.
-
- 5. Following the end of Cycle-4, the Magellan mission will begin a
- "Transition Experiment" in which the periapsis will be intentionally
- lowered to allow the atmospheric drag to slow the spacecraft's
- velocity. This aerobraking maneuver will enable the mission planners
- to circularize the orbit and gather high-resolution gravity data
- closer to the poles of Venus.
