ACE Weekly 10/21/2009 - 10/28/2009

All ACE spacecraft subsystems are performing nominally.

========================================================================
Orbit/Attitude:

No maneuvers were completed this week.  The next attitude maneuver is
scheduled for Friday 10/30/2009.

=======================================================================
OCRs:

DOY 295 (10/22/2009)  1500-1550z  GND-200
A Contingency Exercise is performed annually to confirm that the
spacecraft can be commanded from a software backup.  This exercise runs
the TPOCC software and sends a NO_OP command from a workstation with
software from a backup archive.  This was last performed 11/20/2008
(GND-195).

========================================================================
Activities:

Data Capture:  100%  DOY 291-298 2009


DOY 299 10/26/2009 - Multi-Mission Operations Center (MMOC) Test
There were no problems receiving telemetry or sending commands with
DSS-65.  The spacecraft was commanded to high-rate and SSR data from the
previous pass was redumped.  ACE reformatted data was forwarded for NOAA
space weather.  The ACE Science Center has set up a test port for
real-time data from the MMOC, but a GSFC RIONet gateway request has not
yet been implemented.  Two "St9bad_alloc" errors occurred on the backup
workstation; the errors were not reproducible.
