I wonder if AI is really the right tool to automate the process. Couldn’t it be done more robustly with a simple algorithm that takes todays collision probability models as input?

One every two weeks (about) don't seem "rare" to me.

The vast majority of ESA avoidance manoeuvres are the result of dead satellites or fragments from previous collisions.

It so weird that there is no incentive to fix many usability shortcomings like this one and too tiny UI elements on mobile etc. - all of that despite multiple complaints over years..

As the number of satellites in orbit increases, due to 'mega constellations' such as #Starlink comprising hundreds or even thousands of satellites, today's 'manual' collision avoidance process will become impossible...

How much thrust? How high should it go? And on what information? Data sources will become more complex, risks need to be weighed. I'm not sure 'AI' is the right answer as most (all?) of AI is probably today just ML or more often simple BS - but certainly what ESA & co need won't be a simple one-variable algorithm.
I'm actually wondering if there's not a need to communicate more between all the bodies having satellites in space - just like autonomous cars, if both make an evasive maneuver they might cancel each other out. So there needs to be some kind of communication to avoid this.

It’s meant for code, where the browser isn’t necessary very good at wrapping lines.

How many maneuvers can such a satellite do with it's limited fuel?

Mobile works fine for me and the UI elements as shown honor my text size setting accurately. Using code formatting for non-code results in broken formatting for non-code. This should come as no surprise to anyone. Indents aren’t worth a semantic violation. Use “> ” prefixes like classic email, and optionally italic asterisks if that’s desirable.

#20Of course, inside the article it’s explained that SpaceX didn’t “refuse” to move the satellite, they were politely asked to do so and declined for reasons the author is unaware of. Possibly because they couldn’t move the satellite or had a higher collision tolerance.
