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? |

Yeah, propguy clarified in post #120. From what I've read, TCM-6X wouldnt have been more of a alternate or part 2 of TCM6 rather than clean up a TCM6 gone wrong. Also, I see you quote "12:42:27 UTC" ... if you've taken that from my website, thanks for the visit, and a note that it was just my best guess based on descriptions I had ("so-and-so many hours before landing" which I took as "before EI" based on EI info I had at the time). I havent coded functionality yet for events that are not known (to me) to the second precise. If it was the actual time considered, that'd be spooky -------------------- |
