Launch / Days since Launch = Nov. 7, 1996 / 1372 days
Start of Mapping / Days since Start of Mapping = April 1, 1999 / 496 days Total Mapping Orbits = 6360
Total Orbits = 7963
 
Recent Events:
 
Background Sequences — The spacecraft continues to operate nominally in performing the beta-supplement daily recording and transmission of science data. The mm058 sequence executed successfully from 00-216 (8/03/00) through 00-218 (8/05/00). The mm059 sequence has performed well since it started on 00-219 (8/06/00). It terminates on 00-222 (8/09/00). The mm060 sequence, successfully uplinked on 00-222 (8/09/00), begins executing on 00-223 (8/10/00).
 
The spacecraft successfully completed twelve Radio Science Occultation Egress Scans on 00-221 (8/8/00) and 00-222 (8/9/00). The AACS performed well using the same off-NADIR pointing scheme that proved successful last May.
 
Spacecraft Health:
 
All subsystems report nominal health.
 
Uplinks:
 
There have been 9 uplinks to the spacecraft during the last week, including new star catalogs and ephemeris files, instrument command loads, and the background sequences cited above. There have been 4774 command files radiated to the spacecraft since launch.
 
Upcoming Events:
 
The mm061 background sequence will be uplinked 00-224 (8/11/00). MOLA Polar Scans are scheduled for 00-242 (8/29/00) through 00-246 (9/2/00).
