Before Soviet cosmonaut Yuri Gagarin became the first human in space in 1961, there were the animals. The first astronauts to break through Earth's atmosphere had no understanding of what they were doing. They were dogs and monkeys, strapped into rockets and blasted out of the world they knew – often, never to return.

Animals were part of the space race from the very start. Since 1947, when the United States put fruit flies into a Nazi V-2 Rocket and fired them 100km into the air, animals helped in getting humankind into space. They unwittingly risked things that no human would then dare and made the dream of human space travel a reality.

The most famous of these first animals in space by far is Laika, the Soviet space dog. In 1957, the dog became the first animal to enter the Earth's orbit. Laika's voyage had a tragic end – her spacecraft was rushed by scientists who, determined to get into orbit before the Americans, didn't have time to find a way to bring her home. Her life-support systems failed, the spacecraft heated up, and Laika suffocated shortly after making it into space.

Laika, however, was not the only animal to travel into space. Two years later, in 1959, Soviet dogs Belka and Strelka became the first animals to go into orbit and make it back alive.

Some of the most amazing human accomplishments would never have happened without these animals.

Yuri Gagarin didn't make his flight into space until a dog named Zvezdochka ran the mission as a trial. Alan Shepard, the first American in space, didn't make his flight until a chimpanzee named Ham had done it safely. And John Glenn didn't go into orbit until Enos the chimp tried it first.

Animals made some incredible sacrifices for the sake of human progress – although they had no way of knowing what they were doing. They went through incredible conditions and experiences, many of them never coming back alive. Because of them, humanity achieved the unimaginable.
