It's a ton of money but if I'm going to spend the rest of my life on Mars I don't think I want the Motel 6 package.
My dream is of the rings. When Cassini-Huygens was on the way, I naively supposed that it would get down there and give real closeup shots of them. After arrival, though, when the itinerary was laid out in the popular press, there was no such thing in the offing, and the reason was apparent. It costs as much energy to descend into a gravitational well as it does to ascend out of it. The closest approach to the ring was a one time thing when the orbit was being shaped, and took a steep elliptical form. Once it was rounded out, it was much higher than the rings, and at this point it became impossible to go any deeper, due to fuel limitations.
They have a very good vantage point, of course, but there is no prospect of visual closeups of the actual ring particles, like we see in artists conceptions. This was and remains a real disappoint to me, even though the rewards of the Cassini-Huygens mission are otherwise ample, most particularly the landing of Huygens on Titan, 'cause if that doesn't capture your imagination, I don't know what.
