(Source: Jet Propulsion Laboratory)

(DOY 087/19:00:00 to DOY 094/19:00:00 UTC)

Launch / Days since Launch = Nov. 7, 1996 / 1610 days
Start of Mapping / Days since Start of Mapping = April 1, 1999 / 734 days
Total Mapping Orbits = 9,272
Total Orbits = 10,955

Recent Events:

Background Sequences -- The spacecraft continues to operate nominally in performing the beta-supplement daily recording and transmission of science data. The mm126 sequence executed successfully from 01-088 (3/29/01) through 01-090 (3/31/01). The mm127 sequence has performed well since it started on 01-091 (4/01/01). It terminates on 01-094 (4/04/01). The mm128 sequence, successfully uplinked on 01-093 (4/03/01), begins executing on 01-095 (4/05/01).

Other - MGS performed 6 Roll Only Targeted Observations since the last status report, bringing the total number of ROTOs to 46.

Spacecraft Health:

All subsystems report nominal health.

Uplinks: There have been 15 uplinks to the spacecraft during the past week, including new star catalogs and ephemeris files, instrument command loads, the background sequences cited above, ROTO mini-sequence mz084, and Radio Science Occultation Egress Scan mini-sequence mz085. There have been 5,228 command files radiated to the spacecraft since launch.

Upcoming Events:

The mm129 background sequence will be uplinked on 01-096 (4/06/01). ROTO mini-sequences mz086 and mz087 will be uplinked and executed this next week. Radio Science Occultation Egress Scans, contained in the mz085 mini-sequence, will take place on 01-095 (4/5/01) and 01-096 (4/6/01).
