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: 4571 The landing itself should occur around November 11th. We'll keep you informed |

Questions from an interested non-expert:
I have read that Philae may still partly function if it lands in the wrong orientation (lying on its side, or similar). Is there the possibility that Philae may bounce off the surface, or even not contact the surface? In either of these scenarios, would Philae still be able to transmit back whatever data or images it has already taken? Is there a scenario other than spacecraft system failure where Philae would not be able to transmit data back (like landing upside down, perhaps)? Thanks. |

The landing site is so chaotic... Franckly we don't know : so mainy possibilities of failures and so many possibility of successes... What is certain is that as soon as it touches the ground, the lander tries to screw its footpads into it and there is a small engine on top of it that pushes it downwards to maintain a contact as long as the grip is not firmy done... We'll know for sure in what shape the lander is upon arrival on the 12th ! Hope for the best ! |
