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.
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.
And can solar wind really react with the silicates on comets to produce OH?
