ACE Weekly 06/16/06 - 06/22/06 All ACE spacecraft subsystems are performing nominally. ============================================================================ Orbit/Attitude: Type Attitude Date 06/16/2006 DOY 167 2006 Thrusters 2R 4R+ 4R- Duration 7:15 min Start Time 15:51:03z Stop Time 15:58:18z Start HGA 1.50 deg Stop HGA 6.20 deg Firing 37 pulses The next attitude and station keeping #40 maneuvers are scheduled for Monday, 06/26/06. ============================================================================ 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 07/01/06. RIONET - A licensing issue with the firewalls needs to be resolved before the MOC can be transitioned. 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 String 3 is converted to the RIONET. ============================================================================ Extra Activities: None ============================================================================ Anomalies: DOY 168 (06/17/06) G06-0065 - DSS66 - Antenna Stopped DSS-66 antenna stopped and the station lost telemetry for 9 minutes. When telemetry came back online, RCVR B was out-of-lock. DR M103742. IMPACT: All data was recovered. No commanding to inactive CDH after telemetry was back online, but necessary commands had already been sent. DOY 172 (06/21/06) G06-0066 - DSN SFG Alarms There were problems with the SFG at JPL which cause telemetry dropouts in the last 5 minutes of the pass. DR N103750. IMPACT: None. All pass activties were completed before the dropouts.
