Rocket engineer Alexei Isayev was the force behind the Russian space program. His engines powered the vehicles that launched the first artificial satellites, including the Sputnik-1, the first man into space, and the first unmanned probes to Venus and the moon. He also specialized in small-scale, liquid fueled rocket engines, such as this engine for a S-75 Dvina, a command-guided, high-altitude surface-to-air missile (SAM) - the most widely used air defense missile in history. A striking reminder that the space programs grew from research and development done by the military.
