What if you could send a spaceship zooming around Earth 2,000 times to unlock the secrets of space travel?

The Day Sputnik 2 Flew Higher Than Ever Before!

A tiny spacecraft zoomed into the unknown to test if life could survive in space

Sputnik 2 launched in 1957 to test if life could survive orbiting in space!

On November 3, 1957, the Soviet Union launched Sputnik 2 into space, and it was WAY bigger than the first Sputnik! This spacecraft was about the size of a small car and weighed over 1,100 pounds — that's heavier than a grand piano!

But here's what made Sputnik 2 super special: it carried the first living creature ever to orbit Earth! Scientists wanted to know if a heart could keep beating in space. Could lungs still breathe? Would the strange feeling of weightlessness be dangerous?

Sputnik 2 was packed with amazing science equipment. It had special gadgets to measure cosmic rays — those are tiny invisible particles zooming through space at incredible speeds! It also had instruments to study the Sun's radiation and what happens way up in Earth's atmosphere.

The spacecraft orbited Earth at mind-blowing speeds — about 18,000 miles per hour! That's fast enough to travel from New York to Los Angeles in just 8 minutes! It zoomed around our planet more than 2,000 times before it finally burned up in Earth's atmosphere in April 1958.

💡 Sputnik 2 traveled so fast that it circled the entire Earth in just 103 minutes — faster than most movies!
