Not science. Not based on science.


Your source is incorrect.

Latest Rosetta blog will please the EU supporters, though. blogs.esa.int...

From data collected over the last month, the Alice team discovered that the comet is unusually dark in the ultraviolet and that the comet’s surface – so far – shows no large water-ice patches. Alice is also already detecting both hydrogen and oxygen in the comet’s coma, or atmosphere.

“We’re a bit surprised at just how unreflective the comet’s surface is and how little evidence of exposed water-ice it shows,” says Dr. Alan Stern, Alice principal investigator and an associate vice president of the SwRI Space Science and Engineering Division.


There's already a comment from an EU supporter:

Well isn't that SHOCKING, no water ice detected on the surface, yet hydrogen and oxygen exist in the coma. How can this be without photodissociation of water?? Solar wind's electrical influence is eroding the comet surface. The silicates in the nucleus release oxygen, which react with hydrogen of the solar wind and you've got hydroxyl, which scientists in the past so eagerly used as evidence of water. If you haven't at least tried to "debunk" the electric comet theory, I recommend looking it over so you can get a head start for when we observe it directly.


So, what can we say about the comets' apparently ice-less surfaces, but with plenty of OH in their comas? And can solar wind really react with the silicates on comets to produce OH?

The oxygen is released from silica by a process of electrochemical reduction, and the comet will become more and more porous every time it interacts with the stronger electric field as it gets closer to the Sun, and not from the heat of the Sun melting ice on the surface or in the interior. The solar wind reacts with that released oxygen to produce the OH that they have always called water. IMO.

Doesn't electrochemical reduction of oxygen from silica involve very high temperatures?

I think it can also be done by microwaves, or microwave assisted anyway, and comets produce microwaves. Possibly due to the ion tail acting as a plasma antenna and creating the microwaves somehow, though not sure on that.
It will be interesting to see, if the probe and lander hold up, if the comet does get heated, and if it is by microwaves then there should also be an increase in the electrical charge state, and a larger corona. Hopefully the instruments have the capability to figure out just what is happening as the comet moves closer to the Sun.
