Excluding one superseded elset, todays offerings (so far) from OIG are: Mars Pthfndr r 5.9 2.4 0.0 5.6 d 340 x 141 km 1 24668U 96068B 97331.09776261 .06345767 23716-5 44252-3 0 7491 2 24668 36.3123 79.7308 0150359 222.4970 136.3861 16.12213518 47895 Mars Pthfndr r 5.9 2.4 0.0 5.6 d 324 x 141 km 1 24668U 96068B 97331.40709275 .05248544 24652-5 33473-3 0 7506 2 24668 36.3200 77.5388 0138715 225.7954 133.0944 16.15293474 47949 Mars Pthfndr r 5.9 2.4 0.0 5.6 d 314 x 139 km 1 24668U 96068B 97331.59238022 .05282561 24782-5 29710-3 0 7525 2 24668 36.3123 76.2233 0132529 227.2029 131.7430 16.17321897 47976 Mars Pthfndr r 5.9 2.4 0.0 5.6 d 308 x 138 km 1 24668U 96068B 97331.71578029 .05327643 24883-5 27273-3 0 7539 2 24668 36.3086 75.3321 0128608 228.4750 130.5271 16.18687166 47996 These show it running 9, 30, 51 and 71 seconds late against my SatEvo evolution of yesterday. Clearly the drag has not increased by anything like as much as I expected, perhaps because the atmosphere is still settling down after intense geomagnetic conditions on Sunday - isn't hindsight wonderful :-) My latest prediction is for decay at about November 29.0 (+/-0.2d, but you won't need reminding that my previous prediction was for Nov 28.5 +/-0.3d). SatEvo predicted elsets for the next few hours, by which time I hope to post an update: Mars Pthfndr r 5.9 2.4 0.0 5.6 d 299 x 137 km 1 24668U 96068B 97331.83902917 .06660862 10000-1 30576-3 0 97534 2 24668 36.3083 74.4527 0122524 229.7009 129.2218 16.20597058 48016 Mars Pthfndr r 5.9 2.4 0.0 5.6 d 285 x 137 km 1 24668U 96068B 97332.02369624 .07303487 13432-1 30947-3 0 97530 2 24668 36.3077 73.1312 0112797 231.5433 127.4392 16.23169826 48047 Mars Pthfndr r 5.9 2.4 0.0 5.6 d 265 x 136 km 1 24668U 96068B 97332.26943788 .08552863 18176-1 31594-3 0 97539 2 24668 36.3068 71.3647 0098372 234.0061 125.0778 16.27046549 48081 Mars Pthfndr r 5.9 2.4 0.0 5.6 d 242 x 135 km 1 24668U 96068B 97332.51454994 .10058053 22685-1 31136-3 0 97530 2 24668 36.3058 69.5921 0081479 236.4775 122.7414 16.31594280 48123 With perigee on its southbound leg to the south of the equator, I think decay is most likely between the southbound equator crossing and the following northbound one.
