Mars Global Surveyor Status Report
Wednesday, November 27, 2002 (DOY 324/19:00:00 to DOY 331/19:00:00 UTC)

Launch / Days since Launch = Nov. 7, 1996 / 2212 days
Start of Mapping / Days since Start of Mapping = April 1, 1999 / 1337 days
Total Mapping Orbits = 16,635
Total Orbits = 18,318

Recent Events:

Background Sequences - The spacecraft is operating nominally in performing the beta-supplement daily recording and transmission of science data. The mm229 sequence executed successfully from 02-325 (11/21/02) through 02-327 (11/23/02). The mm230 sequence has performed well since it started on 02-328 (11/24/02). It terminates on 02-331 (11/27/02). The mm231 sequence, successfully uplinked on 02-330 (11/26/02), begins executing near the end of day on 02-331 (11/27/02).

Other - Fifteen Roll Only Targeted Observations (ROTOs) were performed successfully by the mz219, mz220, and mz221 mini-sequences. MGS has completed 418 ROTOs to date.

Spacecraft Health:

Spacecraft subsystems report good health and performance.


There have been 18 uplinks to the spacecraft during the past week, including new star catalog and ephemeris files, instrument command loads, the mz221, & mz222 ROTO mini-sequences, and the mm230 & mm231 background sequences. 7,214 command files have been radiated to the spacecraft since launch.

Upcoming Events:

ROTOs are planned for next week in the mz221, mz222, & mz223 mini-sequences. A DDOR experiment will be conducted on 02-332 (11/28/02). A Nav acceptance test is scheduled for 02-333 (11/29/02). The next series of Radio Science Occultation Egress measurements will occur from 02-336 (12/02/02) to 02-337 (12/03/02) as part of mz223.
