Who is Kessler Syndrome?

Kessler Syndrome is when too many things are floating around in space and they start to crash into each other a lot.

Imagine you're playing with building blocks, if there are only a few, it's easy to stack them up. But if there are hundreds, and they all start tumbling over, it’s like a big block avalanche! That’s what happens in space when too many satellites or pieces of old rockets are flying around.

When satellites, which are like little robots that help us watch TV or find our way, get hit by pieces from old rockets, they might break apart. Then those broken parts can hit other satellites, and boom! More crashes happen. It's like a big game of tag in space, but instead of running, everyone is crashing into each other.

If this keeps happening, it could make it really hard to send more satellites up to space, kind of like if your block tower kept falling every time you added one new block. It might even stop us from using the cool things satellites help with, like maps on our phones or weather forecasts.
