Now, it's time to open a new section devoted to the landing of the Philae lander itself on the nucleus of Comet 67P C-G. Also to answer better the earlier post, http://www.unmannedspaceflight.com/index.p...st&p=212943 and for your information, here is the quick summary (as a "pdf" file) of the events that are expected to occur during landing on the nucleus and after : it's the timeschedule on which we are working to set up our EPO event in Paris. Sequence_ATTERRISSAGE10_UMSF.pdf ( 263.81K ) Number of downloads: 4568 The landing itself should occur around November 11th. We'll keep you informed |

Well, just a thought...
I think they should do whatever they can with battery and finally try to drill into the comet in hope that they can move to some better orientation. There might be a possibility for that because Philae is NOT anchored and comet's gravity is so weak. -------------------- The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.

After attitude and context are known in more detail, they might consider to use the landing gear to get more sun. But they'll be cautious before, to get as many science data back as possible, since mechanical operations are of high risk. |

That is the impression I am getting here also. Jean-Pierre Bibring said something like "Do not put any emphasis on failure of the system ... it is gorgeous where we are!" And I do not think Philae is upside down as has been suggested, I have the impression it is leaning but wedged in place. |

Ha ha, no need for harpoons, just wedge yourself into a crevice. Yes that would have been wonderful, but not in this weak gravity. =) Yet when it is as much in shadow as it is, do suggest something such though. And a confirmation: They will be looking into possible means of adjusting the position of the lander. @Thorsten: I wondered too at first, now I guess it is in relation to the nearby surface and not anything else. |
