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."

Source That is a somewhat confusing report on activities. We did perform TCM6 today and it was very successful. We do not have any more TCM's to perform (that is the somewhat confusing portion of the report). Latest Navigation report show us very close to the entry corridor and estimates of the ground landing ellipse shows over 99% chance of landing on the perfect terrain for InSight (think Bonneville Salts Flat). The last portion is accurate in that the EDL tream is reviewing atmosphere models and entry location to set the last set of parameters for entry. Prop system preheats of the portions of the system used for EDL only (pressurization system and descent components) are well underway and looking good. Just about E-12 hrs and we are ready for EDL! Going to be a great day tomorrow! Go InSight and Go Marco! |
