Inasmuch as i am predicting ample elemental carbon dust all over the surface, we are really doing pretty good. In fact all the evidence is screaming carbon as the primary constituent of this comet. For myself, this is no surprise as i predicted exactly this several years ago. It is now looking more convincing than i had expected.
In the meantime, the cinder is charging up and some of the carbon dust is becoming airborne with more to come.
I have thought of this as a solved problem for so long that i forget that it is not for the rest.ow we have dust dunes, fragile 'rock' conforming to carbon cinders and apparent nodules as well. All conforms to carbon metallurgy and so far we are seeing scant evidence of ice. There may be none. High temperature roasting is quite capable of driving all water away through earlier passes.
I still think there is plenty of water in the Oort cloud, but we are going to have to go and look for it out there..
Europe's Rosetta spacecraft reports unexpectedly bumpy, dusty, and dry discoveries on its new home.
The European Space Agency's Rosetta probe will continue to capture data and photos in 2015 of comet 67P/Churyumov-Gerasimenko, seen in this mosaic image taken in January.
