space dogs

Laika's fellow travelers

Space dogs were dogs launched into space during the early years of space exploration, primarily by the Soviet Union in the 1950s and 1960s.

These animals served as test subjects to study the effects of spaceflight on living organisms before human missions.

Laika, who orbited Earth in 1957, is the most famous: Laika was the first animal to orbit Earth, though she didn't survive the journey.
