Line of sight issues are simply a wattage issue. A gigawatt laser is impervious to rain, a bird, a flock of birds, a bird and the tree it sitting in. Probably the entire forest. Let’s just say there are some solutions well in hand.
"At once, the planets stood between us, forever occluding what we yearn to see.
For existence itself could not repent, the time we spent, and yet
Only whence wielding wattage whole had we defined;
-- an oculus toward which we'd partake of thine.
To space and time, no morphisms apply, no longer shall ye escape our Eye."
