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.
Attached File  Sequence_ATTERRISSAGE10_UMSF.pdf ( 263.81K ) Number of downloads: 4707

The landing itself should occur around November 11th.

We'll keep you informed smile.gif
