LTP06 has been confirmed to run from 2021-12-27T00:00:00.000Z until 2022-04-11T00:00:00Z

Orbital context (with RSW placement decided at SWT #29)

Plots are in GSE (geocentric solar ecliptic) coordinates, so Earth is at [0,0], the Sun is at [1,0]. The plot is the projection of the orbit on the ecliptic plane. 

New definition for the grey shading representing downlink rates:

  • white = maximum downlink rate at which you can empty the SSMM in ~10 days
  • light-grey = SSMM fill state decreases with everyone operating at EID-A rates
  • mid-grey = SSMM fill state increases within RSW (10 instruments operating) and decreases outside RSW (IS-only breakeven rate < downlink rate < inside-RSW breakeven rate )
  • dark-grey = SSMM fill state increases with just IS operating (downlink rate < IS-only breakeven rate)

GAMs, conjunctions and other major platform events

  • SSMM maintenance window  10/01/2022 11:44 -> 12/01/2022 2:20 (ENG_WIN). Instruments will need to be OFF, there will be no receiving of TCs nor storing TM in the SSMM in that period. 
     

Science and calibration planning

Note the text in red highlights adjustments still to be made in SOOP Kitchen plan during Long Term Planning

Overall objectives:

  • Cross-calibration with Earth-based assets (crossing of S-E line occurs on 7 March 2022, 09:00 UTC)
  • High-res observations during first close perihelion

Coordinated science (and cross-calibration) campaigns: (To be confirmed during SOWG#19)

RSW1

  • 2022-03-02 to 03: Offpointing Mosaic to find connection point, i.e. 3 pointings along N-S line, chosen during pVSTP (L_SMALL_MRES_MCAD_Connection-Mosaic)
  • 2022-03-03 to 06: Coordinated campaign to point to the source region of the slow solar wind, that will be measured by IS payload at time of arrival at SC (L_SMALL_HRES_HCAD_Slow-Wind-Connection). Pointing chosen at pVSTP.
  • 2022-03-07: (Predefined) south pole pointing close to Sun-Earth line crossing (R_SMALL_HRES_MCAD_Polar-Observations)
  • 2022-03-07: Pointing to Active Region, chosen at pVSTP, for high-cadence nanoflare observations close to Sun-Earth line crossing (R_BOTH_HRES_HCAD_Nanoflares)
  • 2022-03-07: (Predefined) Full Disk Mosaic for connection science close to Sun-Earth line crossing 
  • 2022-03-07: Coordinated coronal observations, also coordinated with Herschel sounding rocket launch (L_FULL_HRES_MCAD_Coronal-He-Abundance). At sun centre. 
  • 2022-03-08: Pointing to Quiet Sun, at disk centre, for high-cadence nanoflare observations close to Sun-Earth line crossing (R_BOTH_HRES_HCAD_Nanoflares)
  • 2022-03-08: Bright points study, close to Sun-Earth line crossing (R_BOTH_HRES_MCAD_Bright-Points)

RSW2+3

Outside RSWs

  • Limb pointing campaigns during PSP quadratures:
    • 2022-02-22T18:00:00 (POINT_LIMB EAST)
    • 2022-02-26T05:40:00 (POINT_LIMB WEST)

Instrument-specific science:

  • 2022-01-20 to 24: PHI full disk helioseismology campaign (R_FULL_LRES_HCAD_Full-Disk-Helioseismology)

IS calibrations:

none

RS calibrations:

  • Flatfield calibration for PHI/FDT and EUI/FSI (CALIB_OFFPOI_FLATFIELD) on
    • 2022-03-03T04:00:00 (during RSW1, will be commanded through PTR)
    • 2022-03-16T04:00:00 (before RSW2)
    • 2022-04-06T10:00:00 (after RSW3)
  • Straylight calibration using series of SC offpoints, for Metis and SoloHI (CALIB_OFFPOI_STRAYLIGHT) on 2022-03-14T16:50:00
  • Metis polarisation characterisation using SC rolls (CALIB_ROLL_RS) on 2022-03-13T17:00:00
  • PHI-specific (re-)calibration of both FDT and HRT at end RSW1

  1. The time needed for the SSMM SW update and resizing will be marked in the FECS with a ENG_WIN window, e.g. 

    <ENG_WIN time=2022-010T11:44:00Z
           duration="140400"/>

    The activity is expected to be performed in one of the following passes (first is prime, 2nd backup):

    1. According to recent MOC weekly planning meeting emails, the expected event is

      <ENG_WIN time=2022-010T10:44:00Z
