NOVEMBER 2001 ROLL TIMELINE --------------------------- Last Update: 13 November, 19:10 UT Standard Disclaimer: All times are in UT and are estimates. This is the NOMINAL plan, contingencies may occur. As of the last update of this plan, the wheel speeds are fine to proceed with the roll as originally planned. No offsets or changes to the dwell positions are expected. Note: The X-panel heater time-tag command that occurs *during* the roll, will only take about 1 minute out of NRT (if NRT is already enabled). The verification of the command will be done after the nominal NRT is ended. An even more detailed timeline for Wednesday's activities can be found at http://soho.nascom.nasa.gov/soc/timeline_roll2001.detailed SUNDAY -- 11 November 2001 -------------------------- 06:40-14:45 D66 13:00 SUMER will open doors and start observing 17:05-20:50 D27 17:30-17:40 X-panel heater time-tag command scheduled MONDAY -- 12 November 2001 -------------------------- A SOC will be in the EOF to support roll preparations 09:20-14:10 D66 13:55-15:50 D16 18:40-06:45 D46 19:00-22:00 MDI loads, calibrations and tests The SSR dump from the 15:50-18:40 gap will be delayed until about 04:00UT. CDS will upload pre-roll observation plans No X-panel heater commands today - Nominal NRT. TUESDAY -- 13 November 2001 --------------------------- 06:35-08:20 D66 13:45-15:10 D16 (26m automation test) 13:50-23:05 D27 will be fallback during 26m test ~15:30 Test of communications between SOC, CDS, MDI, LASCO, SWAN Note: dry run only 15:30-18:30 NRT available (estimated) 16:45-16:55 NRT paused for X-panel heater time-tag command verification 18:30-20:00 UVCS dedicated NRT for safing ~18:20 CDS pre-roll observations start 20:00-22:30 NRT available (estimated) 21:00 Any limit violation sheets for the roll are due Before COB, all teams confirm with SOCs that everything is set for pre-roll zero-degree observations. *** NO NRT SCHEDULED AFTER 22:30 until after 1st roll profile has ended *** WEDNESDAY -- 14 November 2001 ----------------------------- NOTE: A more detailed version of Wednesday's timeline can be found in http://soho.nascom.nasa.gov/soc/timeline_roll2001.detailed 03:25-06:45 D46 06:45-24:00 VC2 for MDI, handovers/bandwith permitting 06:35-14:10 D66 09:30-10:00 "Maneuver Prep" script FOT will disable offpointing flag function for everyone MDI loop will be kept closed for now 10:00-11:00 "Profile in CRP" script *BEGINS* (note: no profile yet!) 10:00-10:30 Science teams arrive to confirm all nominal roll position observations are finished ***** NOTE the following 3 lines have been advanced by 5 minutes to make ***** sure the first profile starts at 11:00 UT 10:55 All teams should have confirmed all nominal roll position observations are finished MDI confirms they are ready for the FOT to open MDI loop 11:00-22:02 12x30-degree roll profiles, with nominal cadence ~ 54 minutes from one roll profile to the next. 14:00 Handover D66 to D16 16:29-16:31 X-panel heater time-tag command scheduled 13:50-22:50 D16 SOCs will be informed immediately about the end of each roll profile, as a time reference ("END"). NRT will be enabled immediately thereafter. The time profile of each roll position will be as follows: TIME ACTION ------------- END-6 Roll profile starts END SOCs are informed **NRT BEGINS** SOCs inform over loop CDS will move as early as possible END+01 SWAN uploads commands and starts observations END+~5 MDI closes loop END+10 LASCO uploads commands w/varying time delays END+10 CDS uploads commands and starts observations END+35 All teams have informed SOCs they are done with NRT END+35 **NRT ENDS** UNLESS SOCS ASK FOR EXTENSION END+45 All instruments have informed SOCs observations are done MDI has informed/will inform SOCs that loop can be opened END+45 SOCs inform FOT they can open MDI loop and proceed END+49 Start of (N+1)th roll profile *** Each team INFORMS THE SOCs when done with NRT *** Each team INFORMS THE SOCs when observations are done *** MDI INFORMS THE SOCs that their loop can be opened *** On each stop except 180 degrees, MDI should be last one to confirm observations are done. At 180 degrees, LASCO will extend the dwell by about 10 minutes. MDI still needs to confirm that the loop can be opened. There will be a few minutes between the time the SOC says to go ahead and when the next profile starts If we are running far behind, the 360-degree stop will be omitted, going directly from 330 to 270. 22:02-22:15 After finishing observations from the 360 (or 330) degree stop, MDI will confirm that loop can be opened, and we will proceed with Roll profile back to 270 degrees for overnight stay 22:15 NRT Enabled when profile has ended CDS, SWAN load overnight plans SUMER will load overnight observations at this point or later MDI close loop via NRT If there are any limit violations that may occur, submit a limit violation sheet 22:30 AOS/Handover to D46 22:30-06:40 D46 22:50 NRT Disabled (according to nominal plan - note handover!) SVM Reserved activities: Star map, FDF provide current roll attitude + CRS drift Enable offpointing flag for MDI, SUMER, LASCO *** NRT can be enabled when FOT is done with SVM reserve time *** SUMER will load overnight observations if not done earlier THURSDAY -- 15 November 2001 ---------------------------- 00:00-24:00 VC2 for MDI, handovers/bandwith permitting 06:25-14:00 D66 13:40 All teams will confirm that the necessary 270 degree observations are complete MDI will confirm that ISS loop can be opened * CDS has currently scheduled observations to end at 14:28 13:45-22:50 D27 13:45 FOT will resume "Profile in CRP" script FOT will disable offpointing flag function FOT will open MDI loop shortly before roll profile 14:30 Roll profile 270->360 14:43 Roll profile ends/NRT begins (for ONLY 35 minutes) CDS repoints, then loads 14 hour post-roll observations SUMER loads post-roll observations SWAN loads post-roll observations LASCO loads post-roll observations MDI closes loop 15:18 NRT ends 15:30 SVM Reserved Complete "Profile in CRP" script 17:00 SVM Reserved continued Begin "Maneuver End" script Preparations to return to Normal Mode If roll trim is needed, FOT will consult with MDI and open ISS loop or leave it closed, as deemed appropriate. Return to Normal Mode Offpoint flag enabled for UVCS, MDI, LASCO, SUMER (Close MDI loop if necessary) 17:30-17:40 X-panel heater time-tag command scheduled When FOT have completed their SVM reserved activities: 1 hour dedicated NRT for UVCS recovery Then, NRT available for everyone, one at a time on D27 22:30-06:40 D46 MDI may do load FRIDAY -- 16 November 2001 -------------------------- 00:00-06:40 VC2 for MDI, handovers/bandwith permitting 13:50-21:05 D16 16:00-18:30 Intercal1, SUMER/CDS/EIT 18:30-19:00 Sumer closes door, offpoint flag disabled to SUMER 19:03:00 X-panel heater time-tag command scheduled 19:10 Submode change to Submode 6 MDI may do load on either D16 or D46 w/VC2 (time TBD) 20:45-05:00 D46
