ACE Weekly 10/01/04 - 10/07/04 All ACE spacecraft subsystems are performing nominally. No maneuvers were executed this reporting period. The next attitude maneuver is scheduled for 10/08/04. ============================================================================ Orbit Events: The next SEZ crossing will occur in the Nov-Dec time frame. ===================================================================== OCRs Executed: None ===================================================================== Ongoing Activities: TAPS: - Installation of TAPS release 4.3 on the Backup System occurred on 07/20/04. -- FOT testing of this release has completed. - Installation of TAPS Release 4.3 on the Prime System is tentatively scheduled for the week of 10/11/04. ---------------------------------------------------------------------------- Automation (ROBOTT): - ROBOTTv0.9 delivered to String 1 on 09/27/03 (OCR GND_145). -- Performing operations in "Auto" mode on String 1. -- 13 DR fixes in this release. --- 12 DRs have been verified by the FOT to date. --- The last DR to be verified will require ROBOTT to be observed over a period of time to ensure no reoccurrence of the problem. -- 5 DRs have been written against this release. None are considered "Critical" to operations. ============================================================================ Extra Spacecraft Activities: None ===================================================================== Anomalies: DOY 04279 (10/05/2004) ACE Anomaly G04-0116 - TPOCC - Snap Error Message Received the message "snap error ace_cmdstat terminated prematurely" while C&C was running the procedure G_END_DAY.
