We detect ice grains in comet coma (Sol88's insanity incudes that these do not exist when he has cited papers detecting them at 67P!).
Pony up then champ.

Quote:
At the scale of the COSIMA image resolution (pixel size is 14mm), there is no hint of volatiles having left the grains after collection. In other words, there is no indication of an ice–mineral mixture, or of pure icy grains hitting the target. This is in contrast to cometary grains remotely observed, or collected before the Rosetta mission.
Comet 67P/Churyumov-Gerasimenko sheds dust coat accumulated over the past four years

So Reality Checks
Quote:
Anyone with a couple of brains cells will agree that "50% additional production that could come from the sublimation of icy grains" is possible.
Could, if there was indeed icy grains at 67P. Otherwise youve WAAAAYY overestimated water production!

The nucleus is thus a highly porous very dusty body with very little ice

Once we envisioned
Quote:
Whipple’s [2] model of the dirty snowball, the first quantitative model, envisioned cometary nuclei as mostly ice, although our understanding has been evolving more toward mostly rock, particularly for 67P/C-G for which refractory/volatile ratios as high as 6 have been cited
Yup, using mainstream models and Rosetta's data has revised the dirtysnowball to a highly porous dust ball with no ice... ouch!
