Orbital debris is like confetti floating around in space, and sometimes it needs to be cleaned up or moved aside so satellites can keep working.
Imagine you're playing with toy cars on a track. If there are too many toys scattered everywhere, the cars might crash into each other or get stuck. That's what happens with satellites when there’s too much orbital debris, bits of old satellites, tools, and even paint chips flying around in space.
To clean up, engineers sometimes use a net, like catching fish, to grab pieces of debris and pull them away. Sometimes they give the satellite a little push, like giving a toy car a gentle nudge so it can zoom ahead, that’s called reboosting.
How reboosting works
When a satellite needs more energy to stay in its spot, engineers send up a special kind of fuel or use a thruster, which is like a little rocket on the satellite. It fires off tiny bursts of gas, pushing the satellite forward, just like when you blow air into a balloon and let it go.
Sometimes, satellites even team up with other satellites to give each other pushes, like friends helping each other climb a slide! Orbital debris is like confetti floating around in space, and sometimes it needs to be cleaned up or moved aside so satellites can keep working.

Examples
- A satellite uses small thrusters to push itself higher when it starts falling back down.
- Old satellites can be pushed into a 'graveyard' orbit where they won't interfere with others.
