If it's solar powered, how's it going to work in the permanently shadowed craters?
Why not make them large enough to be impossible to swallow?
So, all these pulsars (like everything else in the universe) are always in motion... That motion isn't constant and the direction is also subject to change. In addition to their rate, wouldn't you also have to know their velocity/vector at the time of the pulse?
first step to solar fail?
