So very little ice on the surface, we can at least all agree on that, Tusenfem?
I do not know why we would expect lots of ice on the surface of a comet which passes close by the Sun every 6 year.
So, therefore I cannot understand the "surprise" of the spokes person surface mapping team of ALICE (neither about the low albedo, which has been known for ages). It is this kind of bad public outreach which fuels the ridiculous electric comet claims.
So therefore in standard mainstream thinking it must(or else it's the death of the insert theory here be HIDDEN never to be seen under the surface.
Yes, it is under the surface, because if it would be on the surface it would not come out as jets. Sublimation of surface volatiles does not happen in a specific direction.
So as long as we can not "see" under the surface the standard model will never be falsified....sweet more $$$$ because we can see the -OH in the tail, so there MUST be H2O somewhere ay!
No, you are wrong there, if we see the collimated jets come from the surface, then it comes from under the surface, there is no other way.
Because if your detection of OH in the tail is NOT coming from UV bust'n up H2O then why are we detecting -OH down the tail somewhat?
First of all we are NOT in the tail, and probably never will be in the tail of 67P/CG, we are circling on the day side of the comet, just a tiny detail that you seem to forget. The only times we flew actually through the tail was with ICE at comet 1P/Halley and comet Giacobini-Zinner, all other visits of comets have always been on the front side.
And why would we not have dissociation of H2O through UV or electron impact or other processes working around the comet?
Now, it would be nice to see an actual EC model of how they would generate the OH that they are so fond off. Apparently by working the surface minerals with solar wind protons. However, a quick back of the envelope calculation can easily show that the number of protons impacting the comet is orders of magnitude too small even for the original 2 glasses of water per second emission as measured by MIRO.
