While these are useful videos, they exaggerate size of objects (to scale, objects would be very difficult to see). However, uncertainties & velocities, do lend themselves to an exaggerated 'size'. Concern, yes, just not 'Wall-E'-like. Still, better than past 'Big Sky' thinking.

Indeed Alistair, the sheer volume of objects ≤ 1cm speeding around up there is astronomical, and there's c.900,000 pieces of debris between 1cm-10cm, I believe? Crazy amount of collision warnings and lots of debris currently not tracked. Scary, really.

What is the most scary, and what everyone needs to understand, is if we end up in a Kessler syndrome - there is no way back. Everyone alive today and yet to be born loses access to space. Nothing can get out or come in. We would be trapped forever on this rock.

Kessler syndrome wouldn't mean "no access to space and no way back". Debris can only stay in orbit if it's not colliding with other debris to slow it down, so there's a limit. So it would mainly threaten fragile, long-term satellites, not vehicles promptly leaving LEO.

There goes the recoverable rockets. Be better to use a dispensable one. SAD!

No. do the math. Reusable rockets will have absolutely zero problem with this.

That’s actually a nice graphic demonstrating how difficult polar orbits are...
