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.
