[Various mission costs]

The number you pulled out of your ass for the difference in
productivity between a man on the scene and a remote rover is WAY too
low.

That wasn't me.

I just googled up some costs in a vague attempt to estimate what a
manned mission to Mars would cost. My conclusion was that it would
be very very expensive - enough for many many rovers. Which route
would produce "more science" - I don't know.
