ACE Weekly 02/02/2007 - 02/08/2007 All ACE spacecraft subsystems are performing nominally. ============================================================================ Orbit/Attitude: No attitude maneuvers were completed this week. The next attitude maneuver is scheduled for Friday, 02/09/2007. ============================================================================ OCRs: Step 7 of OCR SEP-110 to turn off internal stimulation still needs to be scheduled. ============================================================================ Activities: DOY 038 (02/07/07) - Preventive maintenance was performed on the ACE MOC Power Distribution Units (PDUs) during the pass. There was no impact to operations. RIONet - Testing and configuration of String 3 continues. * DSN CDR download not yet successful. Troubleshooting continues. Another end to end test has not yet been scheduled. ROBOTT * Release v1.0.3 is tentatively scheduled for late February 2007. This patch release will contain the necessary DR fixes (CDSID#22954 and #23091) to allow ROBOTT to work with the RIONet. Space Link Extension (SLE) - ACE SLE version 2.1 was delivered to the Library on April 28, 2006. Installation in the ACE MOC will not occur until after the MOC is converted to the RIONet. ============================================================================ Anomalies: DOY 035 (02/04/2007) S-ACE-0152 (G07-0013) - ROBOTT killed procedure prematurely The procedure S_OPS_PLBK_COMPLETE started immediately after ULEIS_MOTOR_ERROR completed. However, results checking for ULEIS_MOTOR_ERROR had not completed before ROBOTT started the next procedure. ROBOTT erroneously killed the procedure S_OPS_PLBK_COMPLETE when the results checking for ULEIS_MOTOR_ERROR timed out. This is a known issue (CDSID#21122) which last occurred on 01/05/2007 (AR#G07-0003). IMPACT: Minimal. All data recovered automatically during following support. ================================================ Jacqueline Maldonado Snell Advanced Composition Explorer Flight Operations Team Manager 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
