What dogs flew into space Belka and Strelka? - in detail
The first successful canine mission to space was conducted by the Soviet Union on August 19, 1960. The spacecraft Sputnik 5 carried two strays named Belka (Squirrel) and Strelka (Little Arrow). These dogs became international celebrities after their successful flight, paving the way for human space travel.
Belka and Strelka were chosen from a group of trained dogs due to their calm demeanor and ability to withstand extreme conditions. The mission was crucial in understanding how living organisms would react to weightlessness and radiation exposure. Launched into orbit, the dogs spent a day in space, experiencing zero gravity and the effects of cosmic rays. Throughout the flight, physiological data including heart rate, breathing patterns, and brain activity were continuously monitored.
The successful return of Belka and Strelka provided valuable insights that helped ensure the safety of future human missions into space. Strelka later gave birth to a litter of six puppies, one of which was named Pushinka (Little Flower) and gifted to President John F. Kennedy's family by Nikita Khrushchev. This gesture symbolized the potential for cooperation between nations in space exploration efforts.
Belka and Strelka's journey marked a significant milestone in the history of space exploration, demonstrating that living beings could survive and function normally in space. Their legacy continues to inspire generations of scientists and explorers, highlighting the importance of animal testing in advancing human space travel.
