I posted a message with three OIG elsets and a decay prediction for #24656 = 96- 64 A a few hours ago but it has yet to be reflected on SeeSat-L. Meantime, further elsets have appeared and I'm now able to fit a SatEvo orbit evolution through them. Of course, Vladimir Agapov says this object is the Block D-2 in LEO, though Spacecom have still not catalogued another object from this launch. For now I'll call it "Mars 96(?)". The latest four elsets are: Mars 96? 151 x 137 1 24656U 96064A 96322.46689235 .03446689 12560-4 48899-4 0 39 2 24656 51.5251 14.3524 0010353 193.1058 166.9712 16.48166778 97 Mars 96? 149 x 137 1 24656U 96064A 96322.52750717 .03882494 12559-4 51023-4 0 40 2 24656 51.5241 14.0069 0009452 194.5731 165.5032 16.48693178 109 Mars 96? 146 x 136 1 24656U 96064A 96322.58809741 .03869138 12586-4 47202-4 0 53 2 24656 51.5213 13.6508 0007694 204.7974 155.2667 16.49286694 113 Mars 96? 142 x 132 1 24656U 96064A 96322.70920078 .05053773 12602-4 47595-4 0 61 2 24656 51.5372 12.9538 0007989 202.1388 157.9001 16.50809267 134 The final elsets shows it running 6 sec early with respect to the SatEvo evolution in my previous post. A new SatEvo evolution has a higher ndot (drag) term but satisfies the equator crossing times for these four elsets to within 0.1 sec and leads to decay at about November 18.04 (18th at 01h UT). My predicted elsets are: Mars 96? 139 x 130 1 24656U 96064A 96322.76969833 .08122346 79844-1 64823-4 0 90032 2 24656 51.5241 12.6122 0007117 194.4141 165.5656 16.51897605 144 Mars 96? 136 x 127 1 24656U 96064A 96322.83017188 .09912296 12558+0 67577-4 0 90035 2 24656 51.5238 12.2635 0006273 194.6763 165.3055 16.52979995 155 Mars 96? 131 x 125 1 24656U 96064A 96322.89060119 .12949796 23053+0 72756-4 0 90039 2 24656 51.5234 11.9144 0005298 194.9388 165.0456 16.54342797 163 Mars 96? 126 x 120 1 24656U 96064A 96322.95097233 .19468111 58189+0 84343-4 0 90030 2 24656 51.5229 11.5648 0004098 195.2016 164.7868 16.56238785 178 Mars 96? 115 x 112 1 24656U 96064A 96323.01125265 .48091829 46920+1 13297-3 0 90035 2 24656 51.5221 11.2145 0002348 195.4650 164.5278 16.59720260 182 Alan -- Alan Pickup | COSPAR site 2707: 55d53m48.7s N 3d11m51.2s W 156m asl Edinburgh | Home: alan@wingar.demon.co.uk +44 (0)131 477 9144 Scotland | Royal Observatory: A.Pickup@roe.ac.uk +44 (0)131 668 8224
