I know I was focusing on only what some might call a minor problem with EP's think. I don't. He has all the habits of a usenet troll.

I don't think he knew the difference between space based and Moon based at the time of his post. And EP is now trying to cover his tracks. I think this is how he operates normally.

BTW, the Earth-Moon Lagrange point known as L2 would be out of comms with Earth without something at either L4 or L5. Most proposals I heard of use L1 as the station keeping point. If you use the Sun-Earth L2 we would be in comms most of the time...here is something on L-points Like I need to tell everyone here...

A system of satellites at L-1, L-2, L-4 and L-5 would cover the Moon nicely and could be both comms and I think GPS...or would that be MPS?
