Recently, astronauts drove an Earth-bound rover from the International Space Station. Yes, that's doing it the hard way. :-)
But importantly, this could pave the way for operating a Mars rover interactively from Mars orbit (or a Martian moon), thus saving the trouble and expense of landing a human on the planet who will, presumably, have to be lifted back to Earth at some point. The savings in fuel and equipment that would result from this could be quite significant, making this is a very interesting potential hybrid between manned and robotic missions.
