LTP06 Q1-2022

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)

RS window placement

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.
