ELI5: Explain Like I'm 5

Orbital stationkeeping

Okay kiddo, imagine you're on a really big swing in the park, high up in the air. You want to keep swinging back and forth, but you don't want to bump into any other swings or trees, right? So you have to make sure you stay in your own space.

That's kind of like what it's like in space for satellites and spacecraft. They're also on a swing, but it's called an orbit, and they go around the Earth instead of a pole. And just like you, they have to stay away from other objects in space, like other satellites or debris.

That's where stationkeeping comes in. Stationkeeping is like steering the swing and making sure it stays in the right spot. In space, it means using small rockets or thrusters to adjust the speed and direction of a satellite or spacecraft, so they stay in their orbital path and don't drift too far away or get too close to anything else.

Scientists and engineers use lots of math and science to figure out exactly how much to adjust the satellite's speed and direction to keep it in the right spot. And they have to do this all the time, because gravity and other forces are always trying to pull the satellite off course.

So just like swinging in the park, stationkeeping is a really important thing to do to keep things safe and running smoothly in space!
