I think I heard it mentioned during the press conference today, (I can't find it now), about Rosetta itself possibly landing eventually, similar to what NEAR did at the end of the main mission at Eros? Since it's not like there's anywhere else to go with the remaining delta-v left by the end of 2015, and sunlight levels and activity starting to drop after perihelion, and the low gravity makes the difference between orbiting and 'landing' trivial. The whole thing would weigh a kilo or two, right?
Obviously there's a few more pressing concerns right now, but it's something to eventually think about. |

Could it also be that the neck region is occluded by the two lobes so that less dust and other material contributing to the dark colour is able to aggregate on the surface as the comet travels through interplanetary space? Admittedly, I have little expertise in the science of comet formation so that might be nonsensical (ie. is the surface colour even expected to be due to such aggregation?).
