Recent Events:

Background Sequences – The spacecraft is operating nominally in performing the beta-supplement daily recording and transmission of science data. The mm215 sequence executed successfully from 02-276 (10/03/02) through 02-278 (10/05/02). The mm216 sequence has performed well since it started on 02-279 (10/06/02). It terminates on 02-282 (10/09/02). The mm217 sequence, successfully uplinked on 02-281 (10/08/02), begins executing near the end of day on 02-282 10/09/02).

Other – Fifteen Roll Only Targeted Observations (ROTOs) were performed successfully by the mz206 & mz207 minisequences. MGS has completed 337 ROTOs to date.

Spacecraft Health:

Spacecraft subsystems report good health and status.

Uplinks:

There have been 13 uplinks to the spacecraft during the past week, including new star catalog and ephemeris files, instrument command loads, the mz207 & mz208 ROTO mini-sequences, and the mm216 & mm217 background sequences. 7,090 command files have been radiated to the spacecraft since launch.

Upcoming Events:

ROTOs are planned for next week in the mz208 & mz209 mini-sequences.
