On November 3, 1957, the Soviet Union launched a small dog named Laika into orbit aboard Sputnik 2. She became the first living creature to circle Earth, although the technology to bring her home safely did not exist yet [1][2].

Laika started life as a stray on the streets of Moscow. Soviet scientists chose her because they believed a stray would be tough enough to handle cramped quarters and noise. She weighed only about 5 kilograms and was trained to sit quietly in small spaces and to handle the sound and vibration of rocket launches [1][2].
Sputnik 2 carried Laika into orbit on November 3, 1957, less than a month after the first Sputnik satellite. The spacecraft had no heat shield or landing system. Officials always knew that Laika would not return, but for many years they claimed that she survived for several days before being euthanized. Later reports revealed that she likely died from overheating and stress within hours of liftoff [1][2].Laika mission was still important scientifically. It showed that a living creature could survive launch and experience weightlessness in orbit, at least for a short time. Those results helped pave the way for later missions with dogs that did return alive and eventually for human flights. Today Laika is remembered as both a scientific pioneer and a reminder of the ethical questions that come with high stakes experiments [1][3].
- Use Laika story to talk with kids about space history and also about how our views of animal testing have changed over time [1][3].
- If you are into trivia, remember the date November 3, 1957 as the day the first animal went into orbit [1][2].
Bottom Line
Laika never came back from space, but her short mission told scientists that orbital flight was possible for living beings and pushed the space race into its next phase. Her story is both inspiring and sobering at the same time [1][2][3].
