Launch Alert! Thursday, September 21, 2017 at 20:02 EDT (00:02 UTC on the 22nd) a Russian Soyuz 2.1b rocket will deliver a Russian government Glonass M (52) navigation satellite built by ISS-Reshetnev into orbit from the Plesetsk Cosmodrome, Launch Site 43/4, Northern Russia.

Soyuz 2.1b (Soyuz ST) Rocket: The Soyuz 2.1b (often called Soyuz ST) rocket is a three stage rocket that stands 46.2 m. (152 ft.) tall with a diameter of 10.3 m. (34 ft.) at its base, 2.95 m. (9 ft. 8 in.) along the rocket and is for the most part, a digitally upgraded Soyuz U (analog based) launch vehicle (as is the 2.1a).

Payloads to Orbit (Soyuz 2.1b):

Low Earth Orbit (LEO): 7,800 kg (17,196 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 rocket propellant 1 (RP-1) as fuel and liquid oxygen (LOX) 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 rocket propellant 1 (RP-1) as fuel and liquid oxygen (LOX) 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 (4 chamber) gas generator engines use rocket propellant 1 (RP-1) as fuel and liquid oxygen (LOX) oxidizer, delivering 838.5 kN (188,500 lb.) of thrust at sea level, a specific impulse of 263 s at sea level (320 s vacuum) with a burn time of 118 seconds.
