STEREO Weekly Meeting Minutes for 2024-01-16 (Week 3) 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 2 (Jan 8-14) * On day 009 (Jan 9), the 163rd momentum dump was executed successfully at 1645z, which imparted an estimated delta V of 0.060 m/sec. This was the 82nd momentum dump conducted without gyro use. After thruster operations completed, there was a 0.9 degree of roll angle error. Fine pointing stabilized 2.7 minutes after completion of the momentum dump. * On day 011 (Jan 11), DSN conducted a Mission Network maintenance from 0000z through 0800z. After the maintenance, the MOPs team verified the SLE telemetry and command connectivity with DSN. * On day 011 (Jan 11), during the DSS-26 support, the antenna was stowed and unable to track from 1310z to 1332z, due to high winds. This anomaly resulted in the loss of 22 minutes of real-time telemetry, command, tracking, and SSR data. The MOPs team repositioned the SSR pointers during the track and recovered all the affected data. See DR #G124229 for more information. * The average daily science data return for Ahead was 6.9 Gbits during this week. Week 3 (Jan 15-21) * Ahead has eleven passes during the week, all at 720 kbps, and overall coverage is nominal. * APL will be closed for the Martin Luther King holiday on Monday, Jan 15. Week 4 (Jan 21-28) * Ahead has twelve passes during the week, all at 720 kbps, and overall coverage is nominal. * The fifteen battery discharge event is scheduled for Monday, Jan 22, at 15:25 UT. * The 69th SECCHI stepped calibration roll is scheduled for Tuesday, Jan 23, starting at 05:45 UT. This is the aphelion roll. Week 5 (Jan 29-Feb 4) * Ahead has ten passes during the week, all at 720 kbps, and overall coverage is nominal. Week 6 (Feb 5-11) * Ahead has twelve passes during the week, all at 720 kbps, and overall coverage is nominal. * A DSN Project Interface Test with station 24 is scheduled for Sunday, Feb 11, between 10:45-13:00 UT. Week 7 (Feb 12-18) * Ahead has ten passes during the week, all at 720 kbps, and overall coverage is nominal. Week 8 (Feb 19-25) * Ahead has thirteen passes during the week, all at 720 kbps, and overall coverage is nominal. * The 165th momentum dump is scheduled for Tuesday, Feb 20, with ignition at 15:00 UT.
