"Just" how? Orbital collisions happen at an average of 10km/s, you're going to make what, some kind of sponge that can get hit by a chunk of satellite going ~8x faster than a bullet and absorb it and slow it to a halt without fragmenting at all? Good luck.

Things in orbit are constantly moving, you can't "clear a path" any more than you can, IDK, make a safe route through a forest by walking through it once and moving any bears you encounter a couple of feet.

- ben_w 2y agoWhipple shields fragment, don't they? They slow stuff down enough to not be a hazard to the thing being shielded, but if the goal is mess-reduction I don't see how that will help? https://www.researchgate.net/figure/Whipple-shield-concept_fig1_292756529 https://www.researchgate.net/figure/Whipple-shield-concept_f...
- lupusreal 2y agoThe force of the impact effectively vaporizes part of the shield and the debris. Eventually the shield will be structurally unstable swiss cheese, but that can be modeled and the shield deorbited before it starts to fall apart.
