The core booster, identified as Blok-A is powered by an RD-108 rocket engine. Several minutes into the flight, as the boosters exhaust their fuel, they drop away from the core booster. The boosters are identified as Blok- B, V, G, and D. The six combustion chambers share a single set of fuel pumps and are considered to be one engine.

An RD-107 rocket engine, at the base of each booster, has four main combustion chambers and two smaller vernier engines. Each booster is fueled with kerosene and liquid oxygen. The four strap-on boosters are considered to be the rockets first stage. An instrument section and warhead rode on top of the core stage. The R-7 rocket is comprised of a core stage surrounded by four strap-on boosters. Soyuz spacecraft continue to fly on what has become the worlds most reliable space launcher. Over 50 years after its first flight, descendents of the R-7 are still in regular use. Versions of the rocket would launch the first human into space, the first Lunar probes, even some of the first missions to Venus and Mars. The basic R-7 rocket evolved with the addition of increasingly capable upper stages. Sputnik 1, the first artificial satellite, was launched on an R-7 rocket on 4 October 1957. R-7 Family of Rocketsįirst developed as an ICBM in the 1950's, the R-7 has become one of the most important rockets in the history of space exploration.
