STEREO Weekly Meeting Minutes for 2024-10-29 (Week 44) ANNOUNCEMENTS ------------- * None INSTRUMENT and SPACECRAFT STATUS -------------------------------- * Ahead is operating nominally. PLASTIC is in operational mode, but with a moderately higher than normal background rate. * Four years after the initial loss of communications anomaly with the Behind observatory, NASA has directed to cease periodic recovery operations with the last support on October 17, 2018. DISCUSSION AND OPERATIONS CONSTRAINTS ------------------------------------- Week 43 (Oct 21-27) * On day 296 (Oct 22), during the DSS-65 support, turbo decoder lock was lost briefly at 05:21 UT. This anomaly resulted in the loss of 116 frames of SSR data. The MOPs team repositioned the SSR pointers during the support and recovered all the affected data. See DR #M117427 for more information. * On day 297 (Oct 23), the 171st momentum dump was executed successfully at 18:30 UT, which imparted an estimated delta V of 0.046 m/sec. This was the 90th momentum dump conducted without gyro use. After thruster operations completed, there was a 0.7 degree of roll angle error. Fine pointing stabilized 3.1 minutes after completion of the momentum dump. * The average daily science data return for Ahead was 7.8 Gbits during this week. Week 44 (Oct 28 - Nov 3) * Ahead has nine passes during the week, all at 720 kbps, and overall coverage is nominal. * The ESA Cebreros track scheduled for Wednesday, October 30 has been removed due to the acquisition of additional DSN coverage. * On Wednesday, October 30th there will be a DSN Configuration table change to add Real-time VC6 Telemetry delivery to the MOC. * Daylight Savings Time ends Sunday, Nov 3. Week 45 (Nov 4-10) * Ahead has ten passes during the week, all at 720 kbps, and overall coverage is nominal. * On Wednesday, November 6th, Parker Solar Probe has a Venus flyby, and Solar Orbiter will be collecting observations for a full-disk mosaic. * An ESA New Norcia track is scheduled for Thursday, November 7, from 02:35 to 03:40 UT. Week 46 (Nov 11-17) * Ahead has thirteen passes during the week, all at 720 kbps, and overall coverage is nominal. * APL will be closed on Monday, November 11 for the Veterans Day holiday. Week 47 (Nov 18-24) * Ahead has eleven passes during the week, all at 720 kbps, and overall coverage is nominal. * There is a DSN network maintenance event scheduled for Wednesday, November 20, from 10:25 to 14:25 UT. Week 48 (Nov 25-Dec 01) * Ahead has eleven passes during the week, all at 720 kbps, and overall coverage is nominal. * The 172nd momentum dump is scheduled for Tuesday, November 26th, with ignition at 20:15 UT. * APL will be closed November 28th and 29th for the Thanksgiving holiday. Week 49 (Dec 02-08) * Ahead has ten passes during the week, all at 720 kbps, and overall coverage is nominal.
