Iskra-1 was a prototype of the Polyot rocket launched by the Soviet Union in 1957. This launch marked the beginning of the space age, ushering in an era of exploration and the development of a new generation of space-faring vehicles.
The Iskra-1 rocket was a one-stage design consisting of three main parts: the main engine, the boosters, and the payload. The main engine was a liquid-fueled rocket motor with a thrust of 33 metric tons at liftoff. It was equipped with two RD-107A engines of 11 metric tons thrust each, providing the main thrust for the vehicle. The boosters, called 'rear boosters', provided additional thrust of 10 metric tons each. The payload was the satellite itself, which was encapsulated in a payload fairing.
The 30.045.711 part of Iskra-1 was the Russian product number which was the official way to identify it. It was an important part of the whole launch program that allowed technicians, operators, engineers, and everyone in the space program to refer, track and discuss specific components of the assault.
