  • The latter - targeting from ground. While that sounds daunting, it’s already possible. Sats can aim data laser beams at other sats at even higher relative speeds.

    Beam decoherence is a pretty big problem when you are lasering through the entire atmosphere, and both scenarios require an astounding degree of precision.

    Beam coherence is the only problem with targeting sats from the ground. But remember, these sats come with big telescopes to collect as much light as they can. It may not take a lot of radiative flux to overload their sensors. I wonder how much it will take to completely fry them.
