bruce,
your gut feeling is wrong. The orbital radius for a satellite which rotates
in 27.3 days around the Moon is about 75000km. This is far outside any
realizable orbit around the Moon, due to the pertubations due to the
Sun and the Earth. The only alternative is utilizing the langrangian
points of the Earth-Moon system as Jim King , and B Magnus B{ckstr|m <b@eta.chalmers.se> have already pointed out. As I pointed out to
Rick Baldridge in a private e-mail, the L2 point in the Earth Moon
system has already been utilised (radio astronomy explorer )
though because of the halo orbit, I dont think the emmisions
of homo sapiens cold be ignored completely
