Korabl Sputnik 2

Sputnik 5 was the first spaceflight to send animals into orbit and return them safely back to Earth. Launched on August 19, 1960 it paved the way for the first human orbital flight less than eight months later with Vostok 1. Sputnik 5 was a USSR artificial Earth satellite from the Sputnik space program. It was in fact the second test flight of the Vostok spacecraft, and therefore it is sometimes called Korabl-Sputnik 2 ("korabl" is Russian for "ship").

Mission parameters

Mission highlights

A radio station in Bonn, Germany, was among the first to pick up the signal. On the third orbit, a Swedish radio station confirmed this.

The spacecraft carried two dogs, Belka and Strelka, 40 mice, two rats and a variety of plants on-board. The spacecraft returned to earth the next day and all animals were recovered safely. The spacecraft also carried a television camera which took images of the dogs.

Shortly after the landing, one of Strelka's puppies was sent to Jacqueline Kennedy as a present from the Soviet Union.


The launch time is disputed: Sergei Voevodin gave the time as 08:38:24 UTC while it was officially said to be 08:44:06
