It's a huge concern. It's a very, very big problem in certain orbits around the Earth, low Earth orbit, and also at the geostationary orbits, they're very, that's where you could put, like, communication satellites. And they stay over one spot of the earth. Those are very polluted. You know, there's a lot of junk, and it is very dangerous, and it's a real problem. It's hard to clean up over time. Eventually, even at higher altitudes, there's still a little bit of atmosphere, like, individual atoms. Eventually that slows you down. Those collisions eventually slow you down. So eventually it comes back, but it could take a long, long time.
