It helps that the orbit of Toutatis is extremely precisely known (thanks to all those previous radar observations), but still, it will not be easy for Chang'E 2 Chinese probe (meaning; moon goddess) to succeed. If it does succeed, it will obtain at most two images, one on approach and one on departure, with resolutions of a few tens of meters. This isn't any better than the radar resolution, but images would identify albedo patterns and could help disambiguate radar-derived models of Toutatis' shape. This is an extremely challenging thing for China to attempt, especially given that this is their first deep-space encounter.

I love this stuff. No better time than the present to dive in.
