Did Sputnik Come Back to Earth?

Sputnik 1 was launched in 1957, and just three months later, it spontaneously de-orbited and fell back to Earth. The particles from our atmosphere rise far above any artificial line we've drawn, affecting all of our Earth-orbiting satellites.

Was Sputnik recovered?

It wasn't until noon that Bauch and Rusboldt associated what they had seen with the reported breakup of Sputnik. They returned to the spot and found it, still in the gutter, more than seven hours after it had fallen.

Did Sputnik safely return?

Sputnik 4 was launched two years later, on May 15, 1960. Sputnik 5 was launched on August 19, 1960 with the dogs Belka and Strelka, 40 mice, 2 rats and a variety of plants on board. The spacecraft returned to earth the next day and all animals were recovered safely.
