re: Moonbus
Hello Ed,
I've seen your website years ago (even before becoming a MSNBC space forum regular).
I'm reading "Taking Science to the Moon" by Donald Beattie and he mentions Eugene Shoemaker once protesting about a Moonbus design (one was actually built in the 60's). It's center of gravity was dangerously high (far too many hilly places on the Moon). I'm afraid this one has too high a CG too.
But to move, a wheeled vehicle will certainly be the best solution: low center of gravity, high wheels (to pass over rocks), wheels capable of keeping the dust away from the crew
