It makes its closest approach to the Sun at a toasty 11 million miles—a very close distance for a comet....Scientists find comet 96P interesting because it has an unusual composition
Clearly the religiously held belief of the dirty snowball hypothesis of comet theory has been blown out of the water by direct observation. Despite the claims of the acolyte jonesdumb.

The first indisputable , direct detection of H20 in any comet was made during IR observations of comet Halley from the NASA Kuiper Airborne Observatory (KAO) in December 1985.
When astronomers view the comas of comets spectroscopically, what they actually see is the hydroxyl radical (OH), which they assume to be a residue of water (H2O) broken down by the ultraviolet light of the Sun (photolysis)
Wow! Look at all that non-electric ice!
The first indisputable , direct detection of H20
^^^^So show me the papers that confirm your woo.
How are you getting H2O when the solar wind is not even reaching the comet? No O- to combine with.
You'll find that paper is not taken at all seriously
Conveniently ignoring the data and explanation as usual.

In other words, conveniently ignored as it neither fits with their beliefs nor do they have a viable explanation. You must have learned the same techniques as they, and your application of the technique is spot on.
And what happens when you hit one of Thornhill's 'rocks' with an impactor? It leaves an impossibly large crater, and excavates a shed load of solid ice grains! Whoops.
Nope, as a mission scientist on that page agreed, the mechanism is highly unlikely, and the numbers are way out.

As has been pointed out repeatedly, that which does not agree or is explainable by your failed theories is conveniently ignored and marginalized. It's religious in nature, and a pathetic display of scientific method. Clearly these people are protecting their relevance which is soon to be realized is none.
No, idiot, I'll repeat; the mechanism is highly unlikely
And as of yet, not a comment on the utter failure of the predictions or the successful predictions by Thornhill.
The impact was much more energetic than presumed by mission scientists, Thornhill predicted the energy to exceed that of a simple physical impact. Thornhill- 1; Mission- 0
Sized, volume, and characteristics of the dust plume. Thornhill-2; Mission- 0
Surface geology, open your eyes. Thornhill- 3; Mission- 0
New collimated jets, check. Thornhill- 4; Mission- 0
It goes on, but what's the point, you will ignore and marginalize.
No, idiot, I'll repeat; the mechanism is highly unlikely
But there is the O, and as the direct data from Rosetta shows there are plenty of electrons present... The M.O., ignore, marginalize, and obfuscate. You're a pro!
It is noteworthy that the flux of water ions impinging on the nucleus is frequently of a similar order of magnitude as that of the solar wind. At times, it is even higher than a typical solar wind flux and reaches above 10^11 m-2 s-1.
And why didn't he tell you lot that the crater was waaaaaay too big to have been made in rock?
Photographs taken by the spacecraft showed the comet to be more dusty and less icy than had been expected. The impact generated an unexpectedly large and bright dust cloud
Initial results were surprising as the material excavated by the impact contained more dust and less ice than had been expected. The only models of cometary structure astronomers could positively rule out were the very porous ones which had comets as loose aggregates of material. In addition, the material was finer than expected; scientists compared it to talcum powder rather than sand.
Other materials found while studying the impact included clays, carbonates, sodium, and crystalline silicates which were found by studying the spectroscopy of the impact.[15] Clays and carbonates usually require liquid water to form and sodium is rare in space.
But where is the liquid water?
Use any online cratering program to find out the size of a crater in rock with the DI parameters. 5 - 7m would be the answer.
But where is the liquid water?
"67P from the outburst of 2016 July 03: The ejected material comprised refractory grains of several hundred microns in size, and sub-micron-sized water ice grains."
You keep pushing the simple impact, Thornhill assumes there will be an electric discharge associated. This is how he presumed there would be an ***advanced flash,****
So now water ice is liquid water? Do we need to call it "ice" and "liquid" for you now?
Clays and carbonates usually require liquid water to form....
The presence of carbonates is provocative because, like the phyllosilicates, liquid water was thought to be required to form carbonates from CO2 in the presence of silicates. However, recent work by Toppani et al. (22) suggests that carbonates can be grown from the vapor phase in the presence
of silicates, water, and carbon dioxide vapor.
A hammer stroke exerted on a surface dominantly excites surface waves of the Rayleigh type. By comparison of arrival times at the individual feet, we estimate the propagation velocity of these Rayleigh waves to be at least 80 m/s. With the bulk density of 533 ± 6 kg/m3 as derived from tracking Rosetta (Pätzold et al., Nature, vol. 530, 2016), this velocity translates into a shear modulus of the comet material of at least 3.2 MPa. Shear modulus scales with velocity squared, so when taking into account the formal uncertainties arising from the arrival time inversion, the shear modulus may easily be as large as 10 MPa. ***This is still low compared to solid rock or monocrystalline ice, but is compatible with highly porous materials. ***
