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 |

I don't want to belittle the CE-2 achievement, but I have a question for the scientific data minded: beside basic shape and topography, what can be extracted from this kind of webcam-like, probably uncalibrated images? not much I suspect.
as for another extended mission, I think even merely tracking the probe as long as possible, without firing the engine anymore would provide useful experience for future missions beyond the Moon |

what can be extracted from this kind of webcam-like, probably uncalibrated images? What does "webcam-like" mean? A camera is a camera. These images might be a bit blurry, but they're a lot better IMHO than the science camera's on, for example, Deep Space 1. Most use of panchromatic or relatively broadband color imaging is morphologic and has little to do with calibration. As often as not, calibration is more about removing objectionable image signature, not data analysis, and these images look pretty good. I'm impressed, and even more so by the close flyby distance. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.
