Well, the wheels are each driven independently by an internal motor. The
rocker-bogie suspension is self-evident, but of course it works best if
the wheel and motor sit out at the ends of the suspension. That means
six motors.

I haven't seen a radiation-hardened and mil-spec qualified version of the
Handyboard. Remember, initial cost of an item is insignificant when you
compare it to the cost of space-qualifying it. Besides, the supply of
68HC11 chips seems a little erratic for a program which designs, buys,
tests, and flies over a period of *years*.
