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. |

Break-up of some hydrated state? I couldn't rule this out, easily. But particles should be of very different size, otherwise we would see a fork.
I've also been considering electrostatic interaction (attraction / repulsion) with the spacecraft. But for this, the motion should be almost perfectly parabolic, which I doubt that it is. Collisions with fast-moving tiny grains (less than 300 nm diameter to be invisible as individual particles) may be possible, too. |
