GAMs and conjunctions

  • Superior conjunction from 2025-06-25 to 2025-08-27 (based on 5 deg, dates from CREMA - may need to be updated)
    • This is the longest conjunction(!) of the mission (64 days, with 5 deg constraint)
    • SSMM sizing (at time of writing these sentences, Nov 2021) does not cover this case
