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: 4623 The landing itself should occur around November 11th. We'll keep you informed |

I'm wondering what percent of Phillae's descent rate is due to the mechanical push toward the comet it receives and how much is due to gravity and how that changes over the course of the descent. Has this been described?
Edit: After some more reading and thought, I've concluded that the mechanical shove is almost entirely devoted to counteracting orbital velocity (and not to push the lander toward the comet) and that the descent is pretty much 100% due to gravity. |
