Animals in Space

Laika, a dog, was the first animal to be launched into space. On November 3, 1957, the Soviet Union’s spacecraft, Sputnik 2, carried Laika aboard, marking the first time a living creature embarked on a space mission. While this historic event was a significant milestone in space exploration, it is important to note that Laika’s mission was one-way, as the technology at the time did not allow for the safe return of animals from space. Tragically, Laika did not survive the mission, sparking discussions about ethical treatment of animals in scientific research.
