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:
