On August 20th, 1960, two dogs named Belka and Strelka became the first living beings to safely return from orbiting the Earth. As part of the Soviet Union's space program, these brave canine cosmonauts embarked on a groundbreaking mission that paved the way for human spaceflight.
Belka, which means "Squirrel," and Strelka, meaning "Little Arrow," were both stray dogs found on the streets of Moscow. They were selected for their small size, calm temperament, and ability to withstand the rigorous training required for space travel. The dogs underwent extensive preparation, including being placed in centrifuges to simulate the acceleration of a rocket launch and spending time in isolation to prepare for the solitude of space.
On the historic day, Belka and Strelka, along with a gray rabbit, 42 mice, two rats, and several plants, were launched into space aboard the Sputnik 5 spacecraft. The mission lasted just over 24 hours, during which the spacecraft completed 18 orbits around the Earth. Throughout the flight, the dogs were monitored closely, with their vital signs, such as heart rate and blood pressure, being transmitted back to Earth.
After successfully completing their mission, Belka and Strelka safely returned to Earth, landing in the Soviet Union. They became instant celebrities and were hailed as national heroes. Their success demonstrated that living beings could survive the harsh conditions of spaceflight and paved the way for human exploration of space.
Following their return, Belka and Strelka lived out their lives in comfort, and Strelka even went on to have a litter of puppies. One of her puppies, named Pushinka, was gifted to President John F. Kennedy's daughter, Caroline, by Soviet Premier Nikita Khrushchev, as a symbol of the thawing relations between the two Cold War superpowers.
The legacy of Belka and Strelka's historic flight continues to inspire scientists and space enthusiasts worldwide, reminding us of the incredible achievements made possible through the dedication and bravery of these remarkable animals in the name of science and exploration.
