TODAY – August 31, 2013 at 2005 UTC (1605 EDT) a Land Launch Zenit 3SLB Rocket will lift off from Baikonur Cosmodrome, Pad-45, Launcher-1 (45/1). It will be carrying the AMOS-4 communication satellite which is designed to provide direct-to-home internet, broadband and television to Russia and the Middle East for Spacecom Ltd of Israel.

The Zenit 3SLB rocket is an expendable rocket and is part of the Zenit rocket family which is operated by Land Launch, a subsidiary of Sea Launch. Originally created as boosters for the massive Energia Launch Vehicle, when it was apparent that the mission was not going to take flight the rockets were fitted with stages and the mission changed to lofting satellites into space. The 3SLB is derived from the 2SLB which are modified variants to the Zenit 3SL which is used by Sea Launch to launch from their ocean platform Odyssey.

The vehicle stands at a height of 58.65 meters (192.4 ft.) and has a diameter of 3.9 meters (12.8 ft.) and is a three (3) stage rocket. This particular derivation of the vehicle has a perfect 5-5 launch record thus far.

The Payload Fairing = 10.4 meters (34 ft.) in length and 4.1 (13.5 ft.) meters in diameter.

Upper Stage = the Block DM-SLB Upper Stage is 5.9 meters (19.3 ft.) in length and 3.7 meters (12 ft.) in diameter. It’s powered by a single RD-58M engine that burns Rocket Propellant 1 (Kerosene) as fuel, Liquid oxygen as oxidizer (RP-1/LOX) and has a burn time of 650 seconds.

Second Stage = the second stage, called simply the Zenit Second Stage is 10.4 meters (34 ft.) in length and 3.9 meters (12.8 ft.) in diameter. It’s powered by an RD-120 engine and an RD-8 Vernier Thruster. The second stage also burns Rocket Propellant 1 (Kerosene) and Liquid Oxygen as fuel and oxidizer (RP-1/LOX) and burn time is 315 seconds.

First Stage = or simply, the Zenit 2 First Stage is 32.9 meters (108 ft.) high and 3.9 meters (12.8 ft.) in diameter. It’s powered by a single RD-171 main engine with four combustion chambers and exhaust nozzles and is the post powerful liquid fueled rocket engine in the world. It burns Rocket Propellant-1 (Kerosene) for fuel and Liquid Oxygen as oxidizer (RP-1/LOX) and it burns for 150 seconds.
