This space object became famous and received a mixed response in the world. For the first time in history, it brought a living being in orbit — the dog Laika. The engineers virtually had no time for the construction of "Sputnik-2", since, after the success of the first satellite, it was decided that the second one should be launched on the anniversary of the October Revolution — only a month after the launch of «Sputnik-1». So, the «Sputnik-2» was created in a hurry. Hence, a number of controversial technological decisions were made. The cabin for Laika was a modified version of the cabin used for high-altitude launches of laboratory animals. The radio transmitter was taken from the first satellite’s twin copy. For scientific data transmission, the radio-telemetry complex of the launching rocket was used, which means that the satellite was not designed to separate from the rocket core. In spite of everything, "Sputnik-2" with Laika on board was launched on November 3, 1957. The satellite successfully reached orbit and began transmitting telemetry. Scientists received data on the pulse and the breathing of the dog, as well as Laika’s cardiogram and actogram (graphic data of the animal’s movement). The launch of "Sputnik-2" showed that a living being can survive the launch of the rocket and the state of zero gravity. However, Laika paid for that information with her life — the satellite did not have the descent module, and there was no chance for the dog to return to Earth.
