ACE Weekly 03/12/2008 - 03/18/2008

All ACE spacecraft subsystems are performing nominally.

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

No maneuvers were performed this week.  The next attitude maneuver is scheduled for Wednesday 03/26/2008.

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

None

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

The precal test commands will be stopped before the pass on Wednesday 03/26/2008.  The precal test commands were reinstated at the
request of DSN 26m stations so that they could verify that their CMD system was working properly with SLE.  However, the 34m
stations cannot guarantee that the precal test command won't be sent to the spacecraft after BOT.  Therefore the precal test command
will be removed.  Other missions that use SLE do not send precal test commands.  Note, there is no impact to the spacecraft when the
precal test command is received by the spacecraft.  But it does throw off the FOT's tracking of the command count.

Anomalies:

DOY 084  03/24/2008  S-ACE-0293  G08-0033  ROBOTT/C&C Terminated Procedure
The MOC automation software, ROBOTT, prematurely terminated the SSR redump procedure (s_ops_plbk_complete.prc).  ROBOTT did not see
that the previous procedure had completed and terminated all procedures.  This is a known issue (CDSID#21122) which last occurred on
02/04/2007 (AR#G07-0013).
IMPACT:  Minimal.  No redumps were required.
