  • Start of Mapping / Days since Start of Mapping = April 1, 1999 / 1309 days
  • Total Mapping Orbits = 16,292
  • Total Orbits = 17,975

Recent Events:

Background Sequences - The spacecraft is operating nominally in performing the beta-supplement daily recording and transmission of science data. The mm221 sequence executed successfully from 02-297 (10/24/02) through 02-299 (10/26/02). The mm222 sequence has performed well since it started on 02-300 (10/27/02). It terminates on 02-303 (10/30/02). The mm223 sequence, successfully uplinked on 02-302 (10/29/02), begins executing near the end of day on 02-303 (10/30/02).

Other - Eleven Radio Science Occultation Egress Scans were performed on 02-302 (10/29/02) and 02-303 (10/30/02). Results are pending.

Twelve Roll Only Targeted Observations (ROTOs) were performed successfully by the mz211, mz212 & mz213 mini-sequences. MGS has completed 366 ROTOs to date.

Spacecraft Health:

Spacecraft subsystems report good health and performance.

Uplinks:

There have been 16 uplinks to the spacecraft during the past week, including new star catalog and ephemeris files, instrument command loads, the mz213 ROTO mini-sequence, and the mm222 & mm223 background sequences. 7,143 command files have been radiated to the spacecraft since launch.

Upcoming Events:

ROTOs are planned for next week in the mz213, mz214, & mz215 mini-sequences. A DDOR experiment will be conducted on 02-305 (11/01/02).
