There were no plans to bring her back to Earth, and she lived only a few hours in orbit. Launched on May 15, 1958, Sputnik 3 carried 12 instruments to study the Earth’s upper atmosphere and space, and was the heaviest satellite at the time, weighing 1,327 kilograms. Sputnik 3 was intended to be the first satellite. but with complexity and size, the Soviets were decided to launch Sputnik 1 spacecraft.
