Well Rosetta isn't going to get to 67P/Churyumov-Gerasimenko (Chury) till 2014, but it's not to early to set up a thread. There are a bunch of earth fly-bys, a Mars encounter at 200km in 2007 and a few asteriod passes. Not to mention the mission to land on the comet itself.
Only another nine and a half years to go. |

Does anyone know whether it will be possible to do a mass determination during the Lutetia flyby? Usually these require ultra stable oscillators attached to the transmitters, in order to get a stable enough frequency to track the doppler shift. And you would like to fly as close to your target as possible.
Seeing as how it's an M type, a density measurement, even if it's rough but reasonable (spec. grav +/- 1.5), would be a very useful piece of information. |
