He said that we are still sufficiently unsure about the composition of Phobos to make this likely.Of course if the achondritic fragments could be shown to be Martian, this would increase the liklihood, IMHO.Jon <br />Posted by jonclarke</font></DIV></p><p><font size="2" color="#000000"><strong>Cheers Jon.</strong></font></p><p><font size="2" color="#000000"><strong>Yes, I can see where he is coming from. Perhaps the recent MRO HiRISE obs as well as the post Pheonix EDL Mars Express obs will help. There's nothing wrong with being a Phobosphile. Phobos is a fascinating little world, that deserves further exploration. I am a bit of an Iophile, so that makes me pretty weird.</strong></font></p><p><font size="2" color="#000000"><strong> Where I think the Phobos link is suggested is the fact the achondrite fragments are embedded in very primitive Carbonaceous material.</strong></font></p><p><font size="2" color="#000000"><strong>What I think we can be certain of, is that the Kaidun Meteorite is a real mongrel, with the highly evolved volcanic achondrite fragments being embedded in very primitive unevolved carbonaceous material.</strong></font></p><p><font size="2" color="#000000"><strong>It makes sense through logic that material from a volcanically active body, past or present, was somehow embedded in material on a very primitive unevolved one. Mars & Phobos or Mars & Deimos fit that scenario. </strong></font></p><p><font size="2" color="#000000"><strong>As you say, not enough is known for 100% sure for this meteorite to be a peice of Phobos, only that it does seem very likely. I hope the multispectral obs done by MRO & Mars Express, will help clarify, though really we need a Phobos lander, to sample materials on the surface & even bring a piece back. Likewise with Deimos.</strong></font></p><p><font size="2" color="#000000"><strong>I will do some more digging myself to see how Phobos & Deimos share or differ from what is known about Jupiter's outermost family of retrograding, primitive moons, such as Pasiphae, Ananke, Carme or Sinope. What a shame New Horizons, Galileo or either Voyager, could not have encountered one.</strong></font></p><p><font size="2" color="#000000"><strong>Once again, thank you very much Jon for your input. Like yourself, I would love to know where the Kaidun Meteorite comes from & how highly evolved & very primitive materials became 'mixed up'. </strong></font></p><p><font size="2" color="#000000"><strong>I still think Mars & Phobos or Mars & Deimos is still very likely. Things appear to have gone quiet on PhobosGrunt. Hope it's still happening.</strong></font></p><p><font size="2" color="#000000"><strong>Andrew Brown.</strong></font></p> <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.
