Laika (dog)
Laika was a Soviet space dog who became the first living creature to orbit Earth.
Laika was a Soviet space dog who became the first living creature to orbit Earth. Launched aboard Sputnik 2 on 3 November 1957, she died hours later from overheating and stress. Her flight provided early biological data from space and became one of the most famous moments in the history of space exploration.
Early life and selection
Laika was a stray dog found in Moscow and later chosen for the Soviet space program. Sources describe her as a mongrel and note that she was trained alongside other dogs before selection.
Sputnik 2 mission
Laika launched aboard Sputnik 2 on 3 November 1957, making her the first animal to orbit Earth. The spacecraft was not designed for a return mission, so her survival had not been planned.
Death and aftermath
Laika died a few hours after launch, most likely from overheating and stress. For years, Soviet officials gave incomplete accounts of her fate, and the true circumstances were revealed later.
Scientific and historical significance
Although Laika did not survive, the mission showed that a living passenger could be launched into orbit and provided some of the first biological data on spaceflight. Her flight is widely seen as an important step toward later human missions.
Key facts
- Laika was a stray dog from Moscow selected for the Soviet space program.
- She flew aboard Sputnik 2 on 3 November 1957 and became the first living creature to orbit Earth.
- Laika did not survive the mission; she died within hours from overheating and stress.
- The mission was designed to test whether a living organism could survive launch and conditions in orbit.
- Sputnik 2 re-entered Earth's atmosphere and burned up on 14 April 1958.
Laika’s mission is relevant to Canadian readers as a landmark in the global history of space exploration and bioastronautics, fields that later influenced international and Canadian space science.
