STEREO Weekly Meeting Minutes for 2007-09-11 (Week 37) ANNOUNCEMENTS ------------- * SELENE launch has slipped to day 257 (Sep 14), affecting some schedules. INSTRUMENT AND SPACECRAFT STATUS -------------------------------- * All subsystems on both spacecraft are nominal, except that the Ahead spececraft is currently operating on IMU #2. DISCUSSION AND OPERATIONS CONSTRAINTS ------------------------------------- Week 36 * Average daily downlink was 7.7 gigabits for Ahead, and 8.9 gigabits for Behind. * Launch-specific rules were removed from the EEPROMs on both spacecraft on day 249 (Sep 6). * Station 65 had a transmitter problem during the Behind pass on day 247 (Sep 4), leading to a late uplink and a short gap in the spacecraft data. * JPL performed maintenance on their central data recorder during the Behind pass on day 249 (Sep 6). SSR playback was stopped for 1 hour. All data was played back except for 6% of the SECCHI synoptic partition, which was recovered during the following pass. Week 37 * The SELENE launch has slipped to day 257 (Sep 14). This affects the Ahead pass on station 34 on day 260 (Sep 17). * Behind PLASTIC table load being performed today (Sep 11) with tomorrow as a backup. * Station 55 had a receiver problem during the Behind pass yesterday (Sep 10), and had to switch receivers. This caused an 8 minute gap during playback, at around 17:42 UT. Week 38 * No unusual events scheduled. * One extra pass on Behind, and 2 extra passes on Ahead. Week 39 * There will be a momentum dump on Tuesday, day 268 (Sep 25), at 13:00 for Ahead, and 18:00 for Behind. * DAWN is scheduled for launch on Sep 26 at 11:25. * The DSN schedule delivers only the basic track requirement for this week--there are no extra weeks. DSN schedules are not available yet beyond this week. * PLASTIC will perform there table load on Ahead on Sep 24. Other * The SSC performed some reconfiguration this morning. Some telemetry files are not yet available through the ftp interface--it is still being copied over. There are some problems processing the insitu beacon telemetry which is being investigated.
