Hey again, everyone. This thread will be for discussion of anything that happens between now & landing day, currently 26 Nov US Pacific time (UTC-8 hrs during that part of the year).
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

TCM update:
"At 1:47 p.m. PST (4:47 p.m. EST) engineers successfully conducted a last trajectory correction maneuver to steer the spacecraft within a few kilometers of its targeted entry point over Mars. Engineers still need to conduct a last trajectory correction maneuver to steer the spacecraft toward its entry point over Mars. About two hours before hitting the atmosphere, the entry, descent and landing (EDL) team might also upload some final tweaks to the algorithm that guides the spacecraft safely to the surface."

TCM update: [i]"At 1:47 p.m. PST (4:47 p.m. EST) engineers successfully conducted a last trajectory correction maneuver to steer the spacecraft within a few kilometers of its targeted entry point over Mars. Engineers still need to conduct a last trajectory correction maneuver to steer the spacecraft toward its entry point over Mars. Source This seems very ambiguous. Does anyone have authoritative information that would clarify? Does the press release mean there is to be a TCM-6x at 12:42:27 UTC, or did they just forget to remove the reference to a "last trajectory correction" when they updated the post? Also, can anyone remember if MPL and PHX used a TCM-6 or TCM-6x? |

Also, can anyone remember if MPL and PHX used a TCM-6 or TCM-6x? See my post on the end of page 8. No additional TCM's will be conducted. PHX did not do a TCM6, but we only did it to ensure we were right on the center of the ellipse (all trajectory values pre-TCM6 met entry requirements, just being extra safe, which is a great idea). Got to get to bed to be ready for EDL. Hope you all enjoy the day tomorrow (actually later today). I am sure I will get my track record above 50/50 (MPL and PHX being my previous landing missions). |
