Space domain awareness is like playing hide-and-seek, but in space! We have a lot of things up in space, like satellites and debris from old rockets. Just like in the game, we need to know where these things are so we don't bump into them by accident.
To do this, we use special tools and techniques to keep track of everything in space. These tools can be like toys that help us see where things are and how they move. We put them up in space or down here on Earth, so we can keep an eye on everything.
It's important to keep track of all these things because if something were to collide in space, it could cause a lot of problems. It could damage the satellites we rely on for things like navigation and communication. It could also create more debris that could cause even more collisions!
So, just like how we use our eyes and ears to find our friends when we play hide-and-seek, space domain awareness uses special tools to find everything up in space and keep everyone and everything safe.
