ACE Weekly 12/02/05 - 12/08/05 All ACE spacecraft subsystems are performing nominally. ============================================================================ Orbit/Attitude: Type Attitude Date 12/02/05 DOY 336 2005 Thrusters 2R 4R+ 4R- Duration 12:30 min Start Time 17:14:53z Stop Time 17:27:23z Start HGA 5.98 deg Stop HGA 6.39 deg Firing 64 pulses The next attitude maneuver is scheduled for Wednesday 12/14/05. ============================================================================ OCRs: None ============================================================================ Ongoing Activities: Space Link Extension (SLE) - The first SLE delivery to the Library is expected 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 in the TDF has not been completely configured and tested. The SA's would like the TDF configured with the firewall and RIONET before converting the MOC to the RIONET. ============================================================================ Extra Activities: DOY 339 (12/05/05) - Scrolled through all 30 telemetry section for SSR-A. No new errors were detected on the SSR. DOY 340 (12/06/05) - Scrolled through all 30 telemetry section for SSR-B. No new errors were detected on the SSR. ============================================================================ Anomalies: DOY 336 (12/02/05) G05-0150 2 CMD Echos for every 1 CMD At the completion of the pass with DSS-16 the FOT noticed that 2 cmd echoes were received for each command sent. DR#N103250 IMPACT: It is unknown whether duplicate commands were sent to the spacecraft. The spacecraft would have just ignored the duplicate command. DOY 336 (12/02/05) S05-0054 SWICS Limit Violation SSCGR20V had 1 brief yellow low limit violation (YL <= 17V). 2005-336 00:46:26 - 00:47:02 17.0 Jim Raines notified. IMPACT: Awaiting instructions from Jim Raines.
