ACE Weekly 05/21/2008 - 05/27/2008 All ACE spacecraft subsystems are performing nominally. ============================================================================ Orbit/Attitude: No maneuvers were completed this week. The next attitude maneuver is scheduled for Monday 06/02/2008. =========================================================================== OCRs: None ============================================================================ Activities: Now that the Phoenix mission has landed on Mars, JPL is expected to continue investigating the ISO router problems that resulted in several lost ACE passes over the past month (DOY 124-126 and DOY 134). ============================================================================ Anomalies: DOY 146 05/25/2008 S-ACE-0323 S08-0003 SEPICA 30kV Discharge Flag The SEPICA 30kV Discharge (SSS30KSTATH) and SSSALARMS flagged on DOY 146 2008 at 17:20:01z. SSS30KV and SSS30KI remain nominal at values of 4.0392kV and 41.5mA, respectively. Within the past 7 years, this is the third 30kV discharge flag. DOY 165 2001 16:03:04 DOY 364 2004 06:08:32 DOY 146 2008 17:20:01 Mark Popecki has been notified and OCR SEP-071 is available if the only action needed is to clear the flag (i.e. transient current). IMPACT: Awaiting instructions from Mark Popecki.
