    Have they used laser before or just radio. So this could be
    technology test. Based on received signal, it can provide real
    world information on attenuation and decoherence on the ability to
    signal.

    Can you imagine the diffusion of a laser at those ranges? The target
    search in many many multiples of 64 would be enormous. I also wonder at
    just how immense the output needs to be in order to penetrate space
    gases etc? Or just how fine the Bimorph crystalline trackers need to be?
