Hello, Mir orbital station successfully made its burn and raised own orbit. Engine ignition took place at 12:46:01 UTC, dV=3.0 m/s, burn duration was 137 sec. Orbital parameters on the burn's revolution are (compare pre-burn and post-burn values, post-burn are preliminary after first orbit determination): Pre-burn Post-burn Date 15 Apr 1997 15 Apr 1997 Asc. node time 11:59:55.935 UTC 11:59:52.516 UTC Nodal period, min 92.1885 92.2960 Semimaj. axis, km 6769.50 6774.74 Eccentr. 0.00143 0.000659 Inclination, deg 51.6731 51.6757 Hmin, km 381.63 389.51 Hmax, km 397.16 402.54 Long. of AN, deg 17.0606 17.0746 RAAN 1950.0 40.9872 40.9869 Arg. of perig,deg 359.3208 353.2211 Preliminary EFG post-burn vector: Date 15.04.1997 Time,UTC 11:59:52.516 X, km 6471.89673 Y, km 1987.88027 Z, km 0.00000007 Vx, km/s -1.25199277 Vy, km/s 4.07811517 Vz, km/s 6.02152894 Best regards, Vladimir Agapov. -- Vladimir M.
