Launch Alert! Wednesday, August 16, 2017 at 22:00 UTC (18:00 EDT) a Khrunichev (Russian Government) Proton-M rocket will be launching from the Baikonur Cosmodrome, Kazakhstan to deliver the Blagovest No. 11L communication satellite into orbit.

THE ROCKET: The Khrunichev State Research and Production Space Center, Proton-M rocket is a three-stage, heavy lift rocket that stands on average, 58.2 m (191 ft.) tall, 7.4 m (24 ft.) in diameter and boasts some serious history.  With its first launch back on July 16, 1965 the Proton rocket family has been a workhorse for the Russian space program launching legendary names such as the Salyut series, Mir, and the Russian segments of the International Space Station.  Launches fly out of Sites 81/24 and 200/39 at the Baikonur Cosmodrome, Kazakhstan.

When the Proton is used for commercial launches, it’s marketed by the International Launch Services (ILS) and when it is used for Russian government flights, it’s handled by the Khrunichev State Research and Production Space Center

Payload Fairing (PLF): The Proton PLF flies with either a 13,305 mm (43 ft. 7 in.) “short” or 15,255 mm (50 ft.) “long” two-shell protective enclosure that protects the payload during launch and throughout ascent before being jettisoned in the upper atmosphere.

Breeze-M (Briz-M) Upper Stage: is 2.6 m (8 ft. 7 in.) in length and 4.1 m (13 ft. 1 in.) in diameter and is powered by one S5.98M engine utilizing unsymmetrical dimethylhydrazine (UDMH) for fuel and dinitrogen tetroxide N2O4 as an oxidizer. The Briz-M boasts a specific impulse of 326 sec, delivering 19.62 kN (4,410 lb.) thrust with a burn time of 3,000 seconds.

The 8S812 Third Stage: Proton’s third stage is 4.11 m (13.5 ft.) in length and 4.1 m (13 ft.) in diameter and is powered by one RD-0212 engine utilizing unsymmetrical dimethylhydrazine (UDMH) for fuel and dinitrogen tetroxide N2O4 as an oxidizer. The third stage boasts a specific impulse of 323 sec, delivering 613.8 kN (102,652 lb.) thrust with a burn time of 238 seconds.

The 8S811K Second Stage: Proton’s second stage is 17 m (56 ft.) tall and 4.1 m (13 ft.) in diameter and is powered by three RD-0210 engines and one RD-0211 engines utilizing unsymmetrical dimethylhydrazine (UDMH) for fuel and dinitrogen tetroxide N2O4 as an oxidizer. The second stage boasts a specific impulse of 327 sec, delivering 2,399 kN (539,000 lb.) thrust with a burn time of 206 seconds.

The 8S810K First Stage: Proton’s first stage is 21.18 m (69.6 ft.) tall and 7.4 m (24 ft.) in diameter and is powered by six (6) RD-275 engines which are attached not to the rocket core but to the six strap-on (outboard) fuel tanks. They use unsymmetrical dimethylhydrazine (UDMH) for fuel and dinitrogen tetroxide N2O4 as an oxidizer. The second stage boasts a specific impulse of 285 sec, delivering 10,532 kN (2,368,000 lb.) thrust with a burn time of 108 seconds.

Unsure of launch coverage but you can try Tsenki but it doesn’t like like they plan to air it.
