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 |

Google translate worked for me. There's no new information in here -- in fact it links to Bill Gray's guest blog on planetary.org and to MPML. It provides background on Toutatis and on NEOs. Mostly it asks why the national space agency isn't ballyhooing this more, and then answers the question by explaining that Chang'E 2's ability to get good data on the encounter is limited, concluding that while any data will be interesting, the significance of this is more as an engineering test of the Chinese ability to make the encounter succeed, providing "valuable experience." Seems like a very nice explainer -- hopefully the author will get some traffic from Chinese readers

Google translate worked for me. thanks. i agree that the technology demonstration of the SEL2 dwell, and the departure to the toutatis intercept point, are awesome new levels of space navigation capabilities. it would be nice to get images but your own blog put that in perspective. i'm working to get my own media clients to appreciate the accomplishment and not to set artificially high success criteria. would clementine have faced the same problem with asteroid imaging, or was its survey camera of a different design? |

would clementine have faced the same problem with asteroid imaging, or was its survey camera of a different design? The Clementine cameras were all framing cameras with filter wheels, so no. That said, slewing a pushbroom imager is not that big a deal; see http://mars.jpl.nasa.gov/mgs/msss/camera/i..._98_phobos_rel/ Of course I don't know how CE2's attitude control system works. -------------------- Disclaimer: This post is based on public information only.
