ACE Weekly 02/02/2007 - 02/08/2007

All ACE spacecraft subsystems are performing nominally.

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

No attitude maneuvers were completed this week.  The next attitude maneuver
is scheduled for Friday, 02/09/2007.

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

Step 7 of OCR SEP-110 to turn off internal stimulation still needs to be
scheduled.

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

DOY 038 (02/07/07) - Preventive maintenance was performed on the ACE MOC
Power Distribution Units (PDUs) during the pass.  There was no impact to
operations.

RIONet - Testing and configuration of String 3 continues.
* DSN CDR download not yet successful.  Troubleshooting continues.
Another end to end test has not yet been scheduled.

ROBOTT
* Release v1.0.3 is tentatively scheduled for late February 2007.  This patch
release will contain the necessary DR fixes (CDSID#22954 and #23091) to allow
ROBOTT to work with the RIONet.

Space Link Extension (SLE) - ACE SLE version 2.1 was delivered to the
Library on April 28, 2006.  Installation in the ACE MOC will not occur until
after the MOC is converted to the RIONet.

============================================================================
Anomalies:

DOY 035 (02/04/2007) S-ACE-0152 (G07-0013) - ROBOTT killed procedure 
prematurely
The procedure S_OPS_PLBK_COMPLETE started immediately after ULEIS_MOTOR_ERROR
completed.  However, results checking for ULEIS_MOTOR_ERROR had not completed
before ROBOTT started the next procedure.  ROBOTT erroneously killed the
procedure S_OPS_PLBK_COMPLETE when the results checking for ULEIS_MOTOR_ERROR
timed out.  This is a known issue (CDSID#21122) which last occurred on 
01/05/2007
(AR#G07-0003).
IMPACT: Minimal.  All data recovered automatically during following support.
