I thought it was time to split the subject from the Moon forum.
Admins, can you move the relevant messages here? anyway, just out: an interesting blog article by Bill Gray explaining how he recovered the probe and how he computed the orbit yielding the 13 December flyby date Chang'e 2: The Full Story |

We can look to the past. CE-2 flyby was in many ways similar to the NEAR flyby around Mathilde.
Here are scientific papers about Mathilde and NEAR. CE-2 engineering cameras are not scientific instruments, but it's better than nothing and images from those cameras can be useful for shape determination, topography (as you said), geology (cratering record, boulders), rudimentary photometry etc. Another thing: Flyby was very close, so it's maybe possible to refine mass measurements of Toutatis and with better shape model, we can better derive its density and models of internal composition as well. -------------------- |

It may also provide a bridge between what we are seeing in radar imaged asteroids vs what we are seeing with from spacecraft flybys.
