Hello John, Thank you for your email. I apologize if my posting seemed rude. I was merely defending myself with that disclaimer at the end, as it has been my experience on the met-list that discussing PB's(parent bodies) is often a contentious subject with some people. My post disclaimer was not intentionally directed towards you. I would also like to add, that many believe that certain carbonaceous chondrites originated from cometary debris or the remains of burnt-out old comets, where the icy outer layer has erroded away through exposure and only the rocky core is all thats left. Almahatta Sitta is one of my favorite meteorite additions to my collection. Even though I specialize in collecting planetary meteorites(Lunar Martians, with a few irons thrown in), I made room for that one, as it is the asteroid 2008 TC3 itself that fell to earth.

Thirty-three light-years away, in the constellation Leo the lion, astronomers say they have found a world considerably smaller than Earth, orbiting a dim red-dwarf star. That's something to think about. While scientists have confirmed the existence of more than 700 so-called exoplanets since 1995, most of them have been giant -- many considerably larger than Jupiter. This new world, say the researchers who found it, may be only 5,200 miles across, about two thirds as large as Earth... http://gma.yahoo.com/planet-found-smaller-earth-orbiting-distant-star-203543868--abc-news-tech.html __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Carl wrote: You may be right about Vesta and Eucrites but, without an actual sample return it is still merely an educated guess. I would say that from the data gathered and from the conclusions of the scientists working with the Dawn mission result to more than that of an educated guess. Spectroscopy from the Dawn misson is the most accurate evidence we have so far. The link between Vesta and HED's had been established. Now with the Dawn space probe data, it's verified. To send an expensive sample return mission to Vesta merely further verifiy the link is unneccesary. Ideally, they should. If money was not an issue, I would not mind if they did. But realistically and practically, they won't. The space program should be more focused on new discoveries and exploration. I am not saying that all meteorites classified as eucrites are indeed eucrites from Vesta. The rare odd eucrite may or may not have come from Vesta or one of the many Vestiods. Though they may differ in some way from the majority of other eucrites, how can you say definitively that the anomalous eucrites are from a different PB? Especially seeing how varied diverse Vesta is and it's long history. What you have is a mere possiblity that there is another PB responsible for the few rare odd eucrites. And still that is just one of the many possibilites that could explain them. According to the latest probes of Mercury we still don't know what it's surface rocks would compare to in our collections. Maybe because there is nothing to compare with. Perhaps there are no mercurian meteorites in our collections. Which I believe is the case. There are theories, but no truly substantial connection. This is in contrast to Vesta HED's. It's much easier for a piece of Vesta to escape and fall down, than it is for a piece of Mercury to fall up to Earth's orbit. __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Never underestimate or dismiss Spectroscopy
Generally speaking, stating to the HED clan of meteorites are mainly derived from Vesta is acceptable so long as we understand ( Caveat #1) that they could also be from any of the Vesta family: any of those 6000+ bodies populating the Vesta orbital region. Many of those are over 1 km size and most but not all have Vesta matching spectra/albedos. I'd consider that the many Vestiods of the Vesta family were and are still pieces of their parent body, Vesta. Not counting the odd interloper or co-habitant of the group region, of course. Just like the many martian and lunar meteoriods(martianiod? lunoid?) out there floating in space, blasted off their PB's, were and still are considered pieces of Mars and the Moon respectively. Speaking for myself, it matters very little whether my HED came from Vesta directly or indirectly from a Vestiod. In the end, it's still from Vesta. The second caveat is covered elsewhere in recent list commentary: the fact that we do have some non-Vestian eucrites was panned as insignificant. Well, Au contraire-- the existence of a but a solitary example is proof that the basaltic, sub/minor-planetary differentiation process happened on more than a single body. Adding credibility to the planetary-science model. Naively stating over and over that all eucrites come from Vesta won't make it true. Doing so retards the advancement meteorite science. Keep in mind that the word eucrite and eucritic was a rather broad and loosely used term back in the (old) day(s). Scientists now are more specific in it's usage, accurate and clear with their classifications . So some of those old eucrites and rare non-Vestian eucrites need to be re-examined and possibly reclassified. From Wikipedia: Eucrites are achondritic stony meteorites, many of which originate from the surface of the asteroid 4 Vesta and as such are part of the HED meteorite group. They are the most common achondrite group with well over 100 distinct finds at present. Eucrites consist of basaltic rock from the crust of 4 Vesta or a similar parent body. They are mostly composed of Ca-poor pyroxene, pigeonite, and Ca-rich plagioclase (anorthite). I happen to agree with this definition. Also: Eucrites get their name from the Greek word eukritos meaning easily distinguished. This refers to the silicate minerals in them, which can be easily distinguished because of their relatively large grain size. Eucrite is also a now obsolete term for bytownite-gabbro found on Earth. The term was used as a rock type name for some of the Paleogene igneous rocks of Scotland. __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Never underestimate or dismiss Spectroscopy
If a dealer or someone were to claim that their Tatahouine or NWA 2060 came from Vesta, I would not counter or argue with him. Simply because he has more evidence and proof pointing his way now. You should say that the(1%) rare odd non-Vestan ungrouped anomalous eucrite may or may not be from Vesta instead. At this time, a sample return mission from Mars, Phobos, Europa or Titan would make more sense than a sample return mission from Vesta. On 5/16/12, Benjamin P.

[meteorite-list] Never underestimate or dismiss Spectroscopy
Protoplanet in color May 2012 Recent results of the Dawn mission show that the asteroid Vesta is the only known remnant from a big early phase of planet formation. The cameras help NASA's Dawn space probe the mysteries of the asteroid Vesta. The color images now confirm: Vesta is a relic from the early solar system. Because of the surprisingly heterogeneous celestial body is more like a planet than a primitive asteroid. In addition, recent studies show that most of HED meteorites - a special group of meteorites - are in fact, fragments of Vesta. Since the summer of 2011, two cameras on board the spacecraft orbiting the asteroid Vesta, Dawn - one that is currently in operation, and a backup camera. With this camera system, the scientists, led by the Max-Planck-Institute for Solar System Research (MPS) designed and built, supplied by NASA planetary scientist with the probe image data of the previously almost unexplored asteroid. The framing cameras are equipped with seven different color filters and a clear filter. You can do much more than a normal camera: The color filters can decipher the exact composition of the reflected light from Vesta. Thus, the scientists map the surface of their research subject and draw conclusions about its mineralogical composition. After ten months of meticulous observations of the planet, scientists are now certain that the celestial body is unlike any previously studied asteroid. Vesta is a kind of living fossil prehistory of planet formation. Even the diameter stands, with 525 kilometers, as the third largest asteroid of all. Vesta is a proto-planet, said the lead investigator of the camera crews, Nathues Andreas, and is therefore in a primitive stage of development, from which have been once the giant planets such as Earth and Mars formed. Vesta is probably the last specimen of this species of celestial bodies. The measurements of the other instruments on-board support this interpretation. So far, Vesta was photographed only from a great distance. The observations with the circular orbit in the framing cameras now provided are surprising: No one had expected the large differences in brightness of Vestas surface, explains researcher Lucille Le Corre from MPS. While the brightest spots on Vesta reflect sunlight as much as some snow, the reflectivity of the dark areas is comparable to that of coal. The asteroid shows such a brightness variation not yet observed by a spacecraft. Striking is the sharp difference between the northern and southern hemispheres of the asteroid. This is also reflected in the different colors, which have been identified by scientists at Vestas surface. In particular, the color differences are interesting, reflecting the presence of rocks, the planetary scientists know from studying a particular group of meteorites, the HED meteorites. The acronym stands for Howardites, Diogenites an Eucrites. Even before the mission, these celestial stones were suspected to be fragments of Vesta, as the reflectance spectra of HED meteorites are very similar to those of Vesta. An important goal of the Dawn spacecraft was therefore to find further evidence of the link between Vesta and the HED meteorites. Eucrites are rigid crustal rocks similar to terrestrial basalt, but much brighter, however, diogenites come from greater depths of the crust. The howardites are mixtures of the two rock types, that come from impacts. The pictures show our framing cameras now distinct color differences between regions with rock, which comes from the interior of Vesta, and those that are more influenced by crustal rocks, says Andreas Nathues. We were able to clarify with the observations of other instruments, the Dawn of origin of the HED meteorites. It is actually Vesta. The new data have also revealed that Vesta's color and topography are not generally correlated . This is the case with the Moon: Dark areas correspond to valleys on the moon, bright areas indicate the range of hills. But in this context, not to Vesta. The Dawn spacecraft is at Vesta until the end of August 2012, and then on to her second goal of the dwarf planet Ceres. The mission was launched in September 2007 in the direction of Vesta and arrived July 2011 into an orbit around the asteroid. The dwarf planet Ceres is the largest asteroid between Mars and Jupiter.

Re: [meteorite-list] telescope
Hi John, I remember those telephoto converters sold back in the late 80's-early 90's. I even thought about buying one myself back then. To answer your question, it wouldn't hurt to try that setup. F/16 should be okay for bright objects such as the moon and planets. I do not know what Nikon lens you are using exactly, whether it is a conventional lens or a catadioptric lens. Usually camera lenses have so many glass elements that light has to pass through. More so than a typical refractor telescope would have. Add to that your multiple teleconverters and then the scope converter itself, well needless to say a nice bright sharp picture may be iffy. Less is better sometimes. I would go by the lower end of the guideline in your case. 50x magnification per inch aperture. If I recall, those telephoto converters were meant more for lower power wide field use. Remove a teleconverter or two, and I bet it would be great on open star clusters, bright nebulas, and large galaxies such as Andromeda. On 1/10/12, Pict p...@pict.co.uk wrote: Mmmm.

Sun; meteorite-list@meteoritecentral.com Subject: Re: [meteorite-list] telescope Benjamin, Haven't had a chance to play with this yet but I just managed to find a Nikon Lens scope converter. They were discontinued some time ago and are rare - been looking for a couple of years for a reasonably priced one. You mount it onto a manual focus F mount telephoto and it turns the lens into a telescope with a magnification 1/10th the focal length in mm. Now I have a 600mm f4, two 1.4X teleconverters, and a 2X teleconverter. So in theory I could stack all the teleconverters on and have a 2400mm f16 lens. The front objective on this lens is 160mm in diameter so according to your rule of thumb it should be good for a useful magnification of (50/25)x160 = 320, whereas the actual magnification will be 2400/10=240, well within this. I was assuming the lens would be too dark at f16 to see much. Is this setup comparable to a telescope in the sense that your guidelines for maximum useable magnification still apply? I'd be delighted to hear that I do have a chance of it being useable at this magnification. What do you think? It will be monstrously unwieldy, but I do have a substantial tripod and gimbal head so should be possible to keep it reasonably steady. Regards, John On 10/01/2012 04:13, Benjamin P.

Re: [meteorite-list] Telescope experts
Nah, I would pass on that. Too much central obstruction. Focal length is too short for good planetary views. I'd recommend a good, quality small refractor or tabletop refractor instead, 60mm or bigger. Avoid all the toy scopes. Look for coated(multi-coated is better) achromatic AIR SPACED glass lenses.

Re: [meteorite-list] LOTS OF MOON ROCKS GONE?
I do believe quite a bit of Apollo lunar material has been lost or stolen. Which is unfortunate. But not surprising or unexpected, given human nature. Though it may not be as much as the article makes it seem. The article doesn't say how much(weight-wise) is missing. You have to consider that a certain amount of the Apollo lunar material was destroyed by scientists when they analyzed some samples. This may not have been all accounted for. Also, did they save all the cutting/chipping dust and fragments from the samples since 1969? http://www.physorg.com/news/2011-12-misplaced-nasa-moon-space.html one of the responses from the article above: This is an intriguing story at this time of many intrigues in science and politics. A special investigator from NASA showed up at my lab at the University of Missouri in ~1972 and accused us of losing Moon samples. I showed him receipts for every sample received, every sample melted/vaporized/analyzed, and every sample returned to the Lunar Curator. We sent him back to Houston, but he never told us if he found out why he had been sent on this wild goose chase. With kind regards, Oliver K.

[meteorite-list] Save ANSMET!
http://www.washingtonpost.com/national/health-science/at-the-bottom-of-the-world-a-controversial-search-for-cosmic-leftovers/2011/12/02/gIQAUU8hTO_story.html By Brian Vastag, Published: December 4 The geologist who conceived it called it the poor man’s space program. Sen. John McCain (R-Ariz.) fumed that it was a waste of taxpayer dollars. Meteorite hunter Ralph Harvey simply calls it work. For the 35th year, the United States is mounting its annual campaign to gather space rocks from the wind-hammered icefields of Antarctica. “We’ll be living two to a tent for six weeks, and everybody’s got a snowmobile,” said Harvey, a geologist at Case Western Reserve University who is leading the expedition for the 21st time. “I guess we’re almost like cowboys trying to round up cows.” Except these cows don’t moo. They hunker on the blue ice, half-buried, dark and inert. In the 24-hour sunshine of the austral summer — starting now — meteorites stick out like Angus among Holsteins. “If you want to find stuff falling out of the sky, get a big white sheet,” Harvey said during a phone call from McMurdo Station, the U.S. research base on the continent. “We’ve got a white sheet as big as the continental United States.” Getting to that sheet is a feat of logistical largesse. The eight-person expedition requires 20,000 pounds of gear, hauled first to McMurdo. From there, three giant C-130 transport planes plop the tents, food, water, fuel, snowmobiles, generators and spare parts on the ice halfway to the final destination. From there, many flights of a smaller Otter plane shuttle the expedition to its camp site, which this year is near the Miller Range along the Transantarctic Mountains. “I feel more like I’m moving a city than doing science,” Harvey said. “It will be a three- or four-day process” that will begin Wednesday or Thursday. Scientists say meteorites bombard the Earth from all directions, falling everywhere in roughly equal proportions. But geologic forces concentrate them at the foot of Antarctica’s mountains. Giant ice sheets push against these peaks, churning fallen meteorites toward the surface. Harsh winds knifing down the mountains blow off a layer of snow and ice each year, exposing a new batch. The whole process is a meteorite-generating machine. The expedition collects hundreds each year. “The ice continues to produce more and more meteorites that have been buried below,” said Linda Welzenbach, manager of the National Meteorite Collection at the Smithsonian Institution, where most of the Antarctic finds eventually reside. As a bonus, the continent serves as a natural deep-freeze, keeping the ancient space rocks nearly pristine. Finding them is as straightforward as riding out across the ice with open eyes. Because few Earthly minerals exist out there, anything rocky is bound to come from space. Of every 1,000 meteorites picked off the ice, about 50 hold “outstanding interest to a broad range of scientists,” Harvey said. The smallest are marbles. The largest weigh hundreds of pounds. Some originate at asteroids. Others are free-floating detritus from the birth of the solar system some 4.6 billion years ago. A few — the rarest and, to many scientific minds, the most precious — come from the moon and Mars. An asteroid or comet blasted them into space on an improbable trajectory that eventually landed them at the bottom of the Earth. Nobody knew the Antarctic held such otherworldly wealth until 1969, when a Japanese expedition stumbled on nine unusual rocks near the Queen Fabiola Mountains. It took a few years for Japanese scientists to realize that the rocks hailed from space. (Since then, an ongoing Japanese campaign has collected 30,000 meteorites from Antarctica. Italy, Belgium and China have more recently launched smaller collection programs.) In 1974, word of the Japanese discovery reached William Cassidy, then a geologist at the University of Pittsburgh, who ran the program until 1991. “I realized there had to be some previously unknown process concentrating meteorites in Antarctica,” he wrote in an e-mail. With a grant from the National Science Foundation, Cassidy launched ANSMET, as the program is known. The NSF, NASA and the Smithsonian jointly run it. The ANSMET logo is playful: A penguin in a baseball hat running across the continent, a flaming space rock falling into his glove. Harvey and other scientists credit the program’s longevity to Cassidy’s vision: He insisted that all finds be made available to any scientist in the world. “It almost sounds ridiculous,” said Harvey. “Who goes out and finds a new Egyptian pyramid and says, ‘Hey, you guys study it and I’ll watch’? That’s basically what it is.” Harvey pinned the cost of ANSMET at about $1 million a year. He said it’s a bargain; Cassidy called it “the poor man’s space program.” Sending robots or humans into space to collect such rocks would costs tens of billions. “It’s a unique way to explore the solar system, and we are

Regolith is mostly powdered rock and pebbles from the parent body that may or may not be compacted at the surface. So why should the reflectance spectra from Lutetia's regolith be totally dismissed?

Re: [meteorite-list] Lutetia
Doug, By your own argument, it would be a speculative assumption to consider that Lutetia is not an E-class meteorite, and that it's spectroscopy doesn't reflect in some way it's general composition. Like you say, without a direct sample of Lutetia, no one can be absolutely certain. On this I agree. But for me, all signs are pointing towards --- enstatite. If I were to place a bet, that's what I would be betting on. In the case of Vesta, it was predicted that it was the source for HED's through Spectroscopy long before the chain of Vestoids was found spanning along Vesta's orbit. Granted, Spectroscopy of asteroids from Earth is probably not as accurate as from a space probe in a close flyby. But that's one of the reasons why it's nice that we have Dawn and Rosetta now. __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Impact Melt or Shock Melt?
AFAIK, an impact melt is created from the heat and energy of the collision itself. A contact metamorphism, in-situ. Whereas, a shock melt is created by the energy of the shock waves that travel through the rock and away from the impact site. The shock wave compression generates the heat. Reminds me of the great debate regarding Dhofar 026/461/ect. Whether it is an impact melt or not. First, it was said to be an impact melt breccia. Then others said it's actually a Shocked granulitic breccia. Then the ambiguous Crystalline melt classification.
