Huge idiot here with an honest question: with starlink, could a rogue actor just point a bunch of high-powered lasers at the satellites and brick them?
Cheaper to launch a barrel of metal trash to the Starlink orbits. Or a few barrels. Iran has rockets for that.
In short, likely no(unless the satellites are really sensitive). Otherwise lasers would have negated the fear of ICBMs long ago.
Because the atmosphere absorbs a lot of energy of the laser beam and focusing the laser beam to such a distant target is not easy. So you cannot just use some high powered lasers, as it would be just a bright spot at most. It would be different, if the laser would be space based, but that is out of reach of Iran's capabilities. They might have anti satellite rockets, but using them against US property in space would create other problems for them.
