SpaceX's Starlink dodged 300,000 collisions in 2025. That's nearly 40 maneuvers per satellite, and it's rising fast – possibly hitting 1 million maneuvers in 2027. "If they make a mistake, we’re in really big trouble.” Story by me in @newscientist.com www.newscientist.com/article/2512...

And when one runs out of propellant?

It is made burn in the atmosphere, which releases a ton of (poisonous) heavy metals. Not a huge problem if you have a handful of satellites doing it every few years. A massive issue if you have hundreds or thousand of them burning every year.

I was also thinking that if it doesn’t have enough propellant to manoeuvre it could increase the likelihood of a collision.

Before the propellent finishes they are sent down burning (they would eventually fall down by themselves, but you want to speed it up exactly because you can't manoeuvrer them).
