Comets are overrated

Hi MeteorWayne & Yevaud.<br /><br />AFAIK, the Moon rocks have shown no evidence of hydration at all.<br /><br />They have been 'dry' all along.<br /><br />The Moon clearly at one time, like the Earth was a huge ball of molten rock & metal.<br /><br />However with the Moon's smaller mass & size, cooled off relatively quickly, although there is<br />likely to be some molten rock remaining in the Moon's mantle today.<br /><br />Interesting diagram below, suggesting the Moon has a double layered core, <br />(inner core & outer core) like the Earth.<br /><br />The only other solar system object suspected of having one is the giant Jupiter<br />moon Ganymede.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world. It was extremely large with respect to the overall size of Io and crescent shaped.

Hydrogen likes to combine with oxygen and releases lots of heat when it combines.<br />A shaft of sunlight or the tinyest spark can start rapid burning. If the partal pressure of either gas is low, ignition is not sustained, and thus proceeds very slowly, except at very high temperature. Water is the ash when hydrogen and oxygen combine.<br />The water typically does not condence, nor sublinate, in moon surface high vacuum conditions even during the long night which is about 200 degrees f below zero.<br />In the very thin premoidal atmosphere, there was many times more free hydrogen than than free oxygen, so most of the oxygen was chemically combined with hydrogen and other elements.<br />Is the Moon diagram mainstream opinion? It seems to me that many assumptions are needed, and a wide variety of layers are possible. ie the temperate the core is 500 degrees c = 932 degrees f, so many common compounds and elements are solid or very viscous due to the very high pressure at the center. The fluid layers should separate into many separate layers as many compounds are insoluable in fluids of various kinds. Mixing is likely insufficient to keep insoluable substances homogenized. Please comment, refute and/or embellish. Neil

Hi Neil.<br /><br />Thanks for you very informative post.<br /><br />Yes, the diagram above does appaer to reflect mainstream opinion, based<br />on the seismometers left behind by Apollo & density profiles based on orbiting craft.<br /><br />It is an interesting diagram, as not only showns a double yayer core, but also a <br />double layered mantle. <br /><br />Apart from Earth, only Ganymede is suspected of showing these double layered, 'layers'.<br /><br />Yes the dawn temperatures at the lunar equator at is about minus 167 C.<br /><br />At the poles in permanently shadowed craters maybe minus 230 C (about the same as the <br />Neptune moon Triton or an average <br />British Summer <img src="/images/icons/laugh.gif" /> ).<br /><br />From the Smithsonian / NASA ADS.<br /><br />'Based on the geophysical constraints on velocities of seismic waves, moment of inertia,<br /> and mass, the chemical composition and the internal structure of the Moon were <br />constructed by mathematical simulation of phase relations in the CaO-FeOMgO-Al2O3-<br />SiO2-Fe-FeS system. The method for solving the inverse problem of the determination of <br />the chemical composition, <br />temperature, and physical properties of the Moon, as well as its core size, is based on the <br />minimization of the deviations of the calculated geophysical parameters from <br />observational data. The lunar mantle was shown to be stratified according to the <br />chemical composition. <br />The radius of the lunar core was estimated to be 290-350 km for an Fe core and 460-530 <br />km for an FeS core. The chemical compositions of <br />both the silicate shell (crust + mantle) <br />and the Moon as a whole (enrichment in SiO2 , FeO, <br />and refractory elements, depletion in <br />MgO, and very low Fe/Si ratio) resemble neither the <br />terrestrial matter nor the material <br />of chondrites and achondrites. All this gives <br />evidence that the present-day <br />hypotheses for the Moon's formation from the <br />Earth's mantle do not m <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.
