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. |

Request to the comet gods: puff Philae out of its hole so it lands elsewhere, in the sun and upright of course.

Request to the comet gods: puff Philae out of its hole so it lands elsewhere, in the sun and upright of course. Well, the original plans expected Philae to cook to death by March 2015. If it then instead wakes up from slumber; then, with some luck, the total number of months available for science on the surface could exceed the original plans. IIRC, there was some talk about the possibility to spin up the flywheel as a last-ditch attempt at getting Philae away from its current position before the batteries ran out. If they could successfully pull that off when the insolation at the surrounding planes is habitable, they could possibly extend the lifespan even further. So I think I'll sacrifice some dry ice for the comet gods in the hope that Philae stays put, for now. -------------------- |
