generally when two satellites collide some debris can be shot at a higher orbit which will take forever (or will not) reenter atmosphere. See the scatterplot of debris for the Chinese collision test of 2000: [LINK] See this video for evolution of debris and altitude over time: [VIDEO]

>Do a search for "atmospheric drag" or anything about orbital lifetimes, gabbard diagrams [0] or the like >nothing, instead it equates all constellations and satellites together as the same thing Yet another click bait crummy article, with the obligatory "concerned astronomers" emotional tug on top but no serious engagement. And "big numbers!!" but no sort of context on if or why it's a problem. It's so tiresome how this gets trotted out over and over again. SpaceX's approach isn't bad for debris risks, it's good! The absolute best possible fail safe solution for sats is to have them low enough that they will passively deorbit very quickly without continuous boosts, or even better VLEO orbits where they must maintain aerodynamic orientation as well. Which in turn requires lots of sats that are actively replaced regularly, which in turn helps ensure updates can also be made rapidly based on real experience and they can become extremely refined. Sloppily throwing it all into some vague fear panic of "Kessler Syndrome" is not just wrong it's actively bad for that very reason vs clear differentiation between stuff at 300-550km vs 700+. Also the implication that the utility function for earth-based astronomers is unlimited and they have some special right on top, ignoring the potential future paths for improvement and approaches that would ensure that (a small tax that would go directly towards a fund for space based telescopes say). And so on and so forth. There are real importan

[VIDEO] "Gabbard Diagram for Low Earth Orbit 1959-2021" See how the stuff in the lower left corner speeds up towards the lower left corner? That's low flying debris falling out of space.
