Which of the dogs flew into space and returned? - in detail
The first animal to fly into space and return safely was a dog named Laika, aboard the Soviet spacecraft Sputnik 2 on November 3, 1957. However, it is important to note that while Laika was the first to orbit Earth, she did not survive the journey. The distinction of being the first dog to fly into space and return safely goes to Belka and Strelka, who were launched into space by the Soviet Union on August 19, 1960, aboard the Korabl-Sputnik 2 (also known as Sputnik 5). After spending a day in orbit, they successfully returned to Earth, paving the way for future manned space missions.
