Hello all, A Soyuz-U rocket is scheduled to launch the Progress MS-04 spacecraft the 2016/12/01 at 14:51:52 UTC: http://www.mcc.rsa.ru/progress_mc04.htm The launch will occur from Baikonur Cosmodrome and the spacecraft will make the classical 2-day renzezvous to the ISS. Here are the estimated elsets, based on the times and delta-v data available in the above link: Just after launch, the spacecraft will enter this initial orbit: PROGRESS MS-04 #0 183 X 225 km 1 70000U 16500A 16336.63930292 0.00000000 00000-0 00000+0 0 04 2 70000 51.6437 303.6148 0032419 82.3498 81.0227 16.25722976 00 At 18:14:19 UTC the first maneuver will occur, boosting the spacecraft into a 193 X 301 km orbit: PROGRESS MS-04 #1 193 X 301 km 1 70001U 16501A 16336.76112269 0.00000000 00000-0 00000+0 0 06 2 70001 51.6439 302.9397 0081218 131.5275 25.2775 16.09983895 01 About half orbit later, at 18:53:43 UTC the second maneuver will occur, leaving the MS-04 into a 287 X 301 km orbit: PROGRESS MS-04 #2 287 X 301 km 1 70002U 16502A 16336.78820602 0.00000000 00000-0 00000+0 0 07 2 70002 51.6439 302.7927 0009960 136.7728 177.0828 15.92934708 08 After those two burns the orbit of the spacecraft will be measured, giving the chance to calculate an accurate renzezvous to the ISS. Most surely, the USPACECOM will release TLEs for the spacecraft and rocket shortly after launch. Use the released TLEs for get more accurate positions of the mission. Observers of latitude around 30N will have dusk passes and observers from around 30S will have dawn passes. The docking is expected to be the 2016/12/03 at 16:43:06 UTC, +- three minutes. Webcast will be available here: http://www.tv-tsenki.com/live.php https://www.nasa.gov/multimedia/nasatv/#public Regards, Jon. -- Jon, COSPAR 6242, 42.9453, -2.82839, 623m, Bitoriano, Basque Country. _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Wed Nov 30 2016 - 05:09:21 UTC
