LAUNCH ALERT: Thursday, May 18, 2017 at 11:54 UTC (07:54 EDT) an Arianespace Soyuz 2-1B (Soyuz ST-B) rocket designated VS-17 will be launching the SES-15 communication satellite for the SES Corporation of Luxembourg from the Soyuz Launch Zone (ZLS) or Ensemble de Lancement Soyuz (ELS) at the Guiana Space Centre or Centre Spatial Guyanais (CSG), in Sinnamary, near Kourou, French Guiana.

This will be the 17th launch of the Soyuz from the Guiana Space Center.

Arianespace Soyuz ST (Soyuz at Guiana Space Center aka Soyuz CSG):

The Soyuz ST is a three stage rocket stands 46.2 m. (152 ft.) tall with a diameter of 10.3 m. (34 ft.) at its base. Since 2011, Arianespace had tapped the legendary Soyuz as their medium lift launcher of choice with the massive Ariane 5 carrying the heavy loads and Vega shouldering the lightest payloads to orbit.  Soyuz is often referred to as a four stage rocket with the boosters as the first stage, core as a second stage, third stage and the Fregat as the fourth stage.  Soyuz is supplied by the Russian Federal Space Agency (Roscosmos), TsSKB-Progress and NPO Lavochkin.

Payloads to Orbit (Soyuz ST):

Low Earth Orbit (LEO): 4,850 kg (10,692 lb.)

Sun Synchronous Orbit (SSO): 4,400 kg (9,700 lb.)

Geostationary Transfer Orbit (GTO): 3,250 kg. (7,170 lb.)

Geostationary Earth Orbit (GEO): 1,440 kg. (3,170 lb.)

Payload Fairing: Soyuz’s payload fairing is a two-shell protective enclosure 11.4 m (37 f. 5 in.) in length, 4.11 m (13 f. 6 in.) in diameter and protects the spacecraft during launch and the turbulence of ascent before being jettisoned.

Fregat Upper Stage (3rd stage): The Fregat upper stage is 1.5 m (4 ft. 11 in.) in length with a diameter of 3.35 m (11 ft.). Its single S5.92 engine uses nitrogen tetroxide (N2O4) for fuel and unsymmetrical dimethylhydrazine (UDMH) as an oxidizer, delivering 19.85 kN (4,600 lb.) of thrust and a burn time of 1,100 seconds and can be restarted 20 times in flight.

Second Stage (ST-B): ST-B stage is 6.7 m (22 ft.) in length with a diameter of 2.66 m (8 ft. 9 in.). Its single RD-0124 engine uses liquid oxygen (LOX) as fuel and Kerosene as an oxidizer, delivering 297.9 kN (67,000 lb.) of thrust and a burn time of 270 seconds.

Core Stage (1st stage): Core stage is 27.1 m (89 ft.) in length with a diameter of 2.95 m (9 ft. 8 in.). It single RD-180A engine uses liquid oxygen (LOX) as fuel and Kerosene as an oxidizer, delivering 792.5 kN (178,200 lb.) of thrust and a burn time of 286 seconds.

Boosters: Soyuz’s 4 boosters are each 19.6 m (64 ft.) in length with a diameter of 2.68 m (8ft. 10 in.). Each of their single RD-107A engines uses liquid oxygen (LOX) as fuel and Kerosene as an oxidizer, delivering 838.5 kN (188,500 lb.) of thrust and a burn time of 118 seconds.
