At the height of the Cold War, the space race between the United States and the Soviet Union was reaching its peak. Both powers sought to demonstrate their technological and scientific superiority, and in this context, animals played a crucial role. Laika, a Moscow stray dog, was selected for her endurance and calm temperament. In 1957, she became the first living being to orbit the Earth aboard Sputnik 2.
