ACE Weekly 12/16/05 - 12/22/05 All ACE spacecraft subsystems are performing nominally. ============================================================================ Orbit/Attitude: Type Attitude StationKeeping Date 12/22/05 12/22/05 DOY 256 2005 256 2005 Thrusters 2R 4R+ 4R- 3A 4A Duration 7:24 min 30.4 sec Start Time 16:43:27z 18:16:10z Stop Time 16:50:51z 18:16:41z Start HGA 1.686 deg Stop HGA 6.497 deg Firing 38 pulses Continuous The next attitude maneuver is scheduled for Thursday 12/29/05. ============================================================================ OCRs: None ============================================================================ Ongoing Activities: Space Link Extension (SLE) - The first version of ACE SLE was delivered to the Library on December 14. The delivery to the ACE MOC will not be until January. RIONet - String 3 is anticipated to move to the RIONet in January. The firewall testing in the TDF has been scheduled for the first week in January. ============================================================================ Extra Activities: DOY 355 (12/21/05) Installation of ACE DDS v1.0 from the Library. (Ref AR G05-0152 and AR G05-0153). Installation procedures were red-lined to correct the DDS software. The SysAdmins performed a backup of the DDS after the installation. ============================================================================ Anomalies: DOY 350 (12/16/05) G05-0152 ACEDDS Software Missing The FOT noticed that software on the ACEDDS (ACE Data Distribution Server) was missing. Cause Unknown. DR CDSID 21325 was submitted to remove universal write privileges from the software directory. IMPACTS: Unable to update paging lists and passwords, unable to access pass summary reports. DOY 350 (12/16/05) G05-0153 Library and backup copy of ACEDDS software incorrect The System Administrators used a backup from May 2005 to restore the ACEDDS (Ref AR G05-0152). This backup version was different from the version that was being used for operations. IMPACTS: The DDS webserver was not functioning properly after the backup was installed. The validity of the rest of the ACEDDS software was unknown, so it was powered off for the weekend. The XTE DDS was used as a backup. DOY 350 (12/16/05) G05-0154 Unable to Connect to XTEOST The connection to the XTEOST was not established from the ACEMOC. An update to the Gateway Request was not implemented correctly by NASCOM. NASCOM re-established the gateway rules to XTEOST. IMPACTS: Unable to use XTEOST as the backup until the connectivity issue was resolved. DOY 352 (12/18/05) S05-0055 S3DPU_CONV_SEC_I RH Limit Violation S3DPU_CONV_SEC_I had 1 brief red high limit violation (RH >480 mA). The SSDIDLECTR was ~ 69. 2005-352 18:29:18 - 18:29:20 482.406mA Mark Popecki was notified. IMPACT: Unknown at this time. DOY 354 (12/20/05) G05-0155 ACEDDS Rebooting Unexpectedly The ACEDDS kept rebooting unexpectedly. IMPACTS: Minimal. The motherboard was replaced.
