T+ 120 Engineering Log

The first day of Saturn approach phasing burns was completed without any issues. All EHEs used for these burns performed within normal flight ranges.

The phasing burns being performed are short, 1-5 minute burns designed to reduce the delta V requirement for the SOI burn as well as improve our timing for our arrival at Titan in 25 days. Because of the speed of our Jupiter to Saturn transit, our on-board flight path calculation software was not able to give very accurate solutions for our final approach vectors to Saturn until we are well within Saturn's sphere of influence. We are making 10-12 burns each day and recalculating our closest approach and SOI delta V requirements after each one. The current plan is to continue these phasing burns for the next 9 days, then perform our SOI burn on day 10.

All boards are green at this time.

The remaining milestones for this mission:
  • T+129 Days Terminate Saturn approach phasing burns
  • T+130 Days SOI burn
  • T+145 Days Arrival at Titan and begin construction of Titan Station
  • T+295 Days Departure from Titan Station
  • T+315 Days MCC #7
  • T+350 Days MCC #8
  • T+375 Days MCC #9
  • T+395 Days Arrival at Lunar Station and end of SSTV-01 Mission #2
