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.

Declared sources for Horizons data:
CODE Trajectory files Start (TDB) End (TDB) -------------------------------------- ----------------- ----------------- od002_v1.V0.1 2018-May-05 12:39 2018-May-05 21:00 od037_v1_delTCAL.V0.1 2018-May-05 21:00 2018-Jun-08 00:00 od092_v1.V0.1 2018-Jun-08 00:00 2018-Jul-29 00:01 od102_v1.V0.1 2018-Jul-29 00:01 2018-Nov-25 19:40 4day_landed.V0.1 2018-Nov-25 19:40 2018-Nov-29 19:40 are we missing something?!? |

They made a mistake, seem fixed now (at least the wrong day above) CODE od110_v2_V0.1 2018-Oct-12 19:00 2018-Nov-26 19:40 4day_landed.V0.1 2018-Nov-26 19:40 2018-Nov-29 19:40 It seems Horizons has flight data to entry interface, and from then on static, on the ground coordinates for 4 days. I.e. no EDL data in Horizons, which I dont think they ever had anyway. I suspect, however, they may have pasted the static data a tad too early over the flight data. CODE A.D. 2018-Nov-26 19:39:59.0000 3,543.74 A.D. 2018-Nov-26 19:40:00.0000 3,393.11 (distance from Mars center to landing site) At :39:59 distance is about 20km greater than for nominal EI (125km above equator radius Mars, or 3522 from center), so that data infers EI at 19:40:16. I'll check back in 24 hours, will update my stuff then. The good thing is, Mars will be there, regardless :-) -------------------- |
