What if you could send an entire science lab into space to discover secrets about the universe?

The Day the First Weather Satellite Took Flight!

How a spinning space camera helped us predict the weather

The Soviet Union launched Sputnik 3, a space laboratory with 12 experiments, on May 15, 1958!

Picture this: It's May 15, 1958, and scientists in America are SO excited! They're about to launch something that will change how we understand weather forever — Sputnik 3... wait, that's not right! Actually, on this day, the Soviet Union launched Sputnik 3, a HUGE scientific laboratory into space!

But here's the really cool part: This wasn't just any satellite. Sputnik 3 was packed with scientific instruments — twelve different experiments all crammed into one spacecraft! It was like sending a whole science classroom into orbit!

This incredible machine studied cosmic rays (super-fast particles zooming through space), Earth's magnetic field, and even tiny meteorites. Scientists on the ground could finally learn secrets about space that they'd only dreamed about before.

Sputnik 3 weighed about 2,926 pounds — that's heavier than a small car! It zoomed around Earth every 106 minutes, traveling at incredible speeds. Imagine going around the entire planet in less time than a movie!

💡 Sputnik 3 was supposed to be the FIRST satellite ever launched, but it was too heavy, so the simpler Sputnik 1 went up first instead!
