ACE Weekly Report 09-12-01 All ACE spacecraft subsystems are performing nominally. An attitude maneuver was performed on 09/07/01. The next attitude maneuver is scheduled for 09/14/01. The FOT has completed its checkout of the relocated string 3 in Building 14, W10F. String 2 is the next string scheduled to be moved; the move date is TBD. OCR ULEIS-063 was executed on 9/10/01 to correct the 'erroneous Motor Motion Flag occurrence when autonomous shutter motion is enabled' and re-enable autonomous shutter motion. The error condition had been detected when the autonomous motor mode had been enabled on 7/23/01. The ULEIS team had disabled the autonomous mode on 8/08/01. The FOT has implemented additional monitoring of ULEIS telemetry to monitor the status of the motor motion flag. Anomalies: G01-0092: 9/12/2001 ACE experienced ~5 minute telemetry drop out. The FOT notified the Station and data back online at 14:44:47. No further problems experienced during the support. Insufficient time for FOT to complete recovery of SSR data during the support; all affected SSR slices were recovered during the next support. ================================================ Jacqueline Maldonado Snell Honeywell Technology Solutions Incorporated (HTSI) Goddard Space Flight Center Bldg. 14 Rm W10B, Code 428.2 Greenbelt, MD 20771 Phone: (301) 286-7072 Fax: (301) 286-1729 E-mail: Jacqueline.Snell.1@gsfc.nasa.gov
