SCIENCE ROLL MANEUVER TIMELINE FOR 26 Oct 2009 Standard Disclaimer: All times are in UT and are estimates. No fuel usage SORR on 21 Oct 2009 at ~11 AM local time OCD (SWAN, offpoint flags) due Tuesday 20 October Test communications (speakerphone?) between MDI, SOC office and FOT on Friday 23 Oct 2009 MONDAY -- 26 OCT 2009 --------------------- D65 09:00 - 11:40 D14/D27 13:50 - 23:50 Data from the D65-D14/D27 gap will be put on Tape Recorder, hence no SSR dump on the roll pass UVCS already safed (Friday 23 Oct) SWAN roll preparation - n_fl_roll, first delayed command load Experiment offpoint flag disabled MDI loop opened by FOT just before first profile Roll angles (relative to the orientation at beginning): 0 1 10 2 55 3 100 4 145 5 190 6 235 7 280 8 325 9 10 10 0 Preparation 60 min (includes roll to initial position and transponder swap) Roll segment timeline for Segments 1-9 only - see below comment for Segment 10 (T=0 is the end of roll profile. start times are T+ and in min): Roll profile begins -8 acceleration of 180 s Roll profile ends 0 tell Kevin as soon as it ends Attitude settling begins 0 science may start right away, MDI at T+25 min SWAN load 1 by FOT ASAP after roll completion NRT enabled 2 ASAP after SWAN load uplink MDI loop closing ~5 NRT or FOT CDS commands ~10 NRT; during settling, not time-critical LASCO/EIT commands 15 NRT TC for SSU mapping 25 Science 30 for MDI SSU mapping data dump 30 MDI loop opening 40 by FOT just before next roll profile - tell Sarah Roll profile begins 40 For Segment 10 - back at 0 degrees - don't send SWAN load - instead send n_fl_manrec and then enable NRT for MDI loop closing for regular observations, EIT/LASCO regular loading, and CDS post-roll observations loading Recovery Part 1 (includes roll back to RSL angle and transponder swap) Experiment offpoint flag enabled for MDI and LASCO MDI loop already closed from 0 degree observations Stay in CRP overnight DAY -- 27 OCT 2009 -------------------------- D54 07:25 - 11:25 D24 19:00 - 23:50 D24 Recovery Part 2 - go back to Normal Mode - no instrument activities UVCS will stay safed for the keyhole
