ACE Weekly 08/18/06 - 08/24/06 All ACE spacecraft subsystems are performing nominally. ============================================================================ Orbit/Attitude: Type Attitude Date 08/23/2006 DOY 235 2006 Thrusters 2R 4R- 4R+ Duration 7:44 min Start 15:42:28z Stop 15:50:12z StartHGA 5.08 deg StopHGA 6.13 deg Firing 39 pulses FinalSCMass 1395.759lbs The next attitude maneuver is scheduled for Wednesday, 08/30/06. ============================================================================ OCRs: None ============================================================================ Ongoing Activities: Attitude Training - The FOT continues training on attitude determination, maneuver planning, and maneuver execution. The transition date is tentatively scheduled for 08/18/06. RIONET - The transition to the RIONET on String 3 will tentatively occur around mid-September. Space Link Extension (SLE) - ACE SLE version 2.1 was delivered to the Library on April 28, 2006. The delivery to the ACE MOC will not occur until after the MOC is converted to the RIONET. Multi-Mission MOC - The FOT has begun supporting the effort to determine the feasibility of transferring to a multi-mission MOC. Automation - Development for the next ROBOTT automation release in ongoing on String 3. A ROBOTT SPS release is expected no later than September 18. ============================================================================ Extra Activities: None ============================================================================ Anomalies: DOY 230 (08/18/06) G06-0077 - ACEDDS unable to change password FOT was unable to change the password on the ACEDDS. The sys admins logged in and the password was changed from within the root account. IMPACT: FOT would not have been able to log in without the help of the sys admins. DOY 231 (08/19/06) G06-0078 - offline.gen did not run For unknown reasons, offline.gen did not run after the pass. The script did run nominally the next day and moved and archived all history files. IMPACT: Postpass recorder redump list was not created, but fortunately no redumps were needed. The pass summary file was not generated. History files were not transferred to archive directory until the following day. DOY 233 (08/21/06) G06-0079 - Corrupted DSN Schedule The week 34 schedule file on the DSN Lilypad Server was actually a "Change Log" for passes that occurred in week 33. There was no pass information for the current week in the DSN schedule when ROBOTT went to download it from DSN. DR N103859. IMPACT: The ROBOTT automation schedule was blank, so ROBOTT would not have supported the ACE pass without FOT intervention. DOY 235 (08/23/06) G06-0080 - Incorrect CMD MOD Index The first command was not making it to the spacecraft. Analysis of the 0158 DSN Monitor Data revealed that DSS-66 had the command mod index incorrectly set at 0.43 dB vice 1.69 dB. DR M103823. IMPACT: The first command had to be retransmitted 10 times before it made it to the spacecraft. All commands were received.
