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: 4544 The landing itself should occur around November 11th. We'll keep you informed |

Every time it has been abandoned because of the number and complexity of other operations at the same time. If I am getting this right, is the high number of processes that the computer needs to handle during descent (although is free fall) that prevent transmitting images ? Will Philae transmit live any telemetry at all to Rosetta before touchdown? I am just thinking about the improvements that could be made for a next generation landing probe... -------------------- space scout

This is an interesting paper on the original conceptual design of Philae--from 1997! (just to remind ourselves of the era for which available stable technologies were being considered, and what incredible now-stable things might be in a next-gen lander) http://www.open.ac.uk/personalpages/a.j.ba...ine/capcom.html No descent imaging was even described in that paper, so the present capability and operational plan is a privilege, considering. Whole careers go by in the course of one such mission! -------------------- --
