[meteorite-list] No wonder Bonhams was a bust
No, buyers' premium was 20% and California sales tax (without a resale number) is 8%. ...So add 28% Jason There you have your answer, in part. Add 28% means subtract 50% of the potential bidders, including me. I watched that auction, and was scared away from bidding by the man in a black ski-mask and a Bonham's jacket on. Call me naive, but tacking on an extra 30% after the gavel (almost) is highway robbery. And I thought eBay fees were ridiculous. I guess I'll never bid on a Bonham's auction.

Re: [meteorite-list] Trinitite --Correction--UPDATE
Dear Mike just when you think you have the book ready to publish and you know all there is to know someone changes a chapter... So let me revisit what we thought we knew about trinitie formation I got this blurb today from Geology at about.com but the link to the WSMR Military website isn't there yet again. Since the new theory was published in 2005 I stand partially corrected about the origin of trinitite--there is a fallback theory paper! The trinitite appears to have formed as sand was sucked up into the nuclear fireball and fell back in a rain of molten glass, according to a new theory(link to http://www.wsmr.army.mil/wsmr.asp?pg=ypage=591). It was always assumed that trinitite formed on the ground under the fireball's direct glare, but science thrives by revisiting assumptions in the search for truer explanations. from Geology at about.com Newsletter All references to the new theory have been removed from the White Sands Missile Range web site and aren't on the Los Alamos Labs public site. So I don't know if the new theory has been withdrawn. The rayed star pattern of deposition, the lack of any trinitie more than 1200 ft from GZ and the fact that the trinitite deposits were generally concentric with GZ--e.g. not scattered down wind, makes me think that any fall back theory will need to go a long way to explain this away. In the interest of fairness and previous discussion I thought I'd share this snippet pending locating the text of the theory.

Re: [meteorite-list] Update on Colorado fireball
I had the privilege to map the geology of the north part of the Ft Carson base in 2002-2003. The area is very rugged, much like Glorieta, and is full of rocks. Not the best hunting grounds. I remember driving down one of the base roads in a remote area, and was ambushed by several men that were dressed like terrorists (masks, black clothing and machine guns). They thought I was part of the exercise. I explained who I was and we all had a laugh, but I nearly soiled myself! The area north of the base is extremely rugged with a few thousand feet in elevation changes, very remote (don't get lost) and full of mountain lions. I am not trying to scare you away, but this is no walk in the park.

[meteorite-list] Meteor Explodes Over Colorado
Space Weather News for Dec. 6, 2008 http://spaceweather.com COLORADO FIREBALL: Last night, a fireball one hundred times brighter than the full Moon lit up the sky near Colorado Springs, Colorado. Astronomer Chris Peterson photographed the event using an all-sky video camera dedicated to meteor studies. In seven years of operation, this is the brightest fireball I've ever recorded. I estimate the terminal explosion at magnitude -18. Meteors this bright are called superbolides; they are caused by small (meter-class) asteroids and are likely to pepper the ground with meteorites when they explode. Visit http://spaceweather.com to watch the fireball video and contribute sighting reports that could help pinpoint any meteoritic debris. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Meteorites Could Have Thickened Primordial Soup
http://www.sciencenews.org/view/generic/id/39124/title/Meteorites_could Meteorites could have thickened primordial soup High temperatures and pressures of impacts can create complex organic chemicals, tests show By Sid Perkins Science News December 8, 2008 In recent geological ages, large extraterrestrial bodies colliding with Earth have been associated with worldwide extinctions, but new experiments show that massive impacts that occurred early in our planet's history could have created the raw materials for life. The hellish temperatures and pressures generated when an extraterrestrial object strikes Earth at speeds of several kilometers per second are enough to shatter and vaporize rock (SN: 6/15/02, p. 378). Yet part of such an immense burst of energy can trigger chemical reactions that generate complex organic substances from basic inorganic ingredients, says Takeshi Kakegawa, a geochemist at Tohoku University in Sendai, Japan. He and his colleagues conducted lab experiments intended to simulate a common meteorite striking one of Earth's early oceans. The team reports its findings online December 7 in Nature Geoscience. First, the researchers filled tiny, thick-walled canisters of stainless steel with various mixtures of carbon, iron and nickel - common constituents of meteorites - and water, ammonia and nitrogen, significant components of the ancient ocean and atmosphere. Then, the team fired the canisters at a solid target. The shock of impact briefly subjected the enclosed materials to temperatures approaching 4,700° Celsius and pressures about 60,000 times that of the atmosphere at sea level. These temperature and pressures are similar to those that would be caused by a large meteorite slamming into Earth at about 2 kilometers per second, says Kakegawa. After each test, Kakegawa and his team cleaned off the outside of the canister, drilled a hole in it, and then extracted and analyzed the contents. In two of the team's five tests, impacts created fatty acids like those found in cell membranes, and also generated a variety of amines, the ingredients for amino acids, Kakegawa says. In one test, the impact generated substantial amounts of glycine, the smallest of the 20 amino acids commonly found in proteins. None of the organic chemicals generated by the impacts was a contaminant from any poor handling, Kakegawa proposes. That's because all of the carbon in those resulting substances was the carbon-13 isotope, the same rare form that he and his colleagues used for the original mixture. Scientists estimate that around 4 billion billion (1018) metric tons of meteorites fell to Earth between 4.4 billion and 3.8 billion years ago. Even though meteorites only contain, on average, about 0.1 percent carbon, oceanic impacts during this era could have generated at least one hundred billion (1011) metric tons of organic substances, the researchers estimate. Although these chemicals couldn't have survived the conditions at ground zero of the impact, they probably could have formed in the more-tolerable temperatures present in the plumes of steam and vaporized rock that spewed skyward in the aftermath. The team's new analyses are a nice piece of work, says George Cody, a geoscientist at the Carnegie Institution for Science in Washington, D.C. A number of previous studies have hinted that the building blocks of life could have been generated by lightning in Earth's ancient atmosphere (SN: 6/3/00, p. 363) or at deep-sea hydrothermal vents (SN: 9/9/00, p. 175; SN: 2/2/08, p. 67). Having multiple sources of such raw materials makes determining the origin of life that much more difficult, Cody adds. However, he notes, the more we learn, the more we see how early Earth was rich with organic compounds. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] HiRISE Camera Captures High-Resolution 3D Images of Mars
FROM: Lori Stiles (520-626-4402; [EMAIL PROTECTED]) HiRISE Camera Captures High-Resolution 3D Images of Mars December 8, 2008 The High Resolution Science Imaging Experiment, or HiRISE, team based at The University of Arizona today released 362 three-dimensional images of Mars taken by the HiRISE camera on NASA's Mars Reconnaissance Orbiter. Other Mars-orbiting cameras have taken 3D views of Mars, but the HiRISE camera - the most powerful camera ever to orbit another planet - can resolve features as small as one meter, or 40 inches, across. It's really remarkable to see Martian rocks and features on the scale of a person in 3D, said Alfred McEwen of UA's Lunar and Planetary Laboratory, HiRISE principal investigator. The level of detail is just much, much greater than anything previously seen from orbit. The 3D images, or anaglyphs, can be viewed on the HiRISE Web site (http://hirise.lpl.arizona.edu/anaglyph) with inexpensive color filter glasses commonly used for viewing 3D images and movies. The HiRISE Web site links to information on where to purchase and how to make 3D red-cyan filter glasses. Without 3D glasses, the Mars images appear out of register. (In Tucson, UA's Flandrau Science Center, 1601 E. University Blvd., and Starizona, 5757 N. Oracle Road, sell red-cyan filter glasses for $2 each.) Seen in HiRISE 3D, Mars becomes a collection of deep panoramic views that leap out from the computer screen. You'd swear you could touch the terrain, HiRISE operations manager Eric Eliason said. Striking stereo views include: * Sixty-meter tall, or 200-foot-tall fractured mounds, probably composed of solidified lava, on the southern edge of Elysium Planitia. The fractured surface suggests that lava pushed the surface into domes, uplifting some sides along the same fracture higher than others. * Spectacular layers exposed on the floor about 2-and-a-half miles, or 4 kilometers, below the rim of Candor Chasma, which is a large canyon in the Valles Marineris system. The canyon may once have been filled to its rim by sedimentary layers of sand and dust-sized particles, but these have since eroded, leaving patterns of elongated hills and layered terrain that has been turned and folded in many angles and directions. * Groups of gullies at different elevations along the wall of an unnamed crater in Terra Cimmeria. The anaglyph image provides three-dimensional perspective on the depth of the gullies and the amount of material deposited below the gullies. Geological evidence suggests that the gullies may have formed by subsurface water, rather than by snow or ice melting on the surface. Other dramatic anaglyphs show a huge jumbled mass of rock that includes megabreccia at a central peak in Ritchey crater, ejecta-formed channels and mudflows at Hale crater, tightly folded rock layers lining the floor of Tithonium Chasm, spiders created by carbon dioxide venting through south polar layered deposits, and Martian glacier flows. Eliason and the team at HiROC, the High Resolution Imaging Operations Center on the UA campus, began processing stereo images in October. They automated some of the software used in processing HiRISE images so two images of a stereo pair could be fed into the software pipeline and correlated automatically. The real advance here is making this process semi-automated so we can really crank through all these huge images, McEwen said. Producing anaglyphs from stereo pairs is otherwise a tedious, time-consuming effort. The HiRISE camera has so far taken 950 stereo image pairs. The camera features a half-meter, or 20-inch, diameter primary mirror and a focal plane mechanism that can acquire up to a 3.6 megapixel image in about 11 seconds. The anaglyphs are among 1,642 observations containing 3.6 terabytes of data and 148,000 image products that HiRISE released today to the Planetary Data System, or the PDS, the NASA mission data archive. Since HiRISE began the science phase of its mission in November 2006, the HiRISE team has released a total 867,430 image products, or 30.2 terabytes of data. That is by far the greatest volume of data a space experiment has delivered to the PDS, and well more than twice the data volume some HiRISE team members expected to get during the primary science phase. The HIRISE camera was designed to take images at high-convergence angles so researchers can calculate the thickness of surface features to within about 10 inches, or 25 centimeters. High-convergence angles used to get quantitative measurements aren't always best for making anaglyphs, McEwen said. In addition, if the two stereo images on two different orbits were taken far enough apart in time, the illumination or air opacity may have changed, or frost or dust devils may have appeared in one of the images, so paired images don't always match that well, he added. Nevertheless, many of these stereo anaglyphs are very interesting and useful to us in understanding the topography, McEwen said. There's a

[meteorite-list] Polarizers way cheap! Big ones!
Hi list, All my images involve polarizers in one way or an other and over the last couple years I have had many inquiries of where to get polarizers cheap. I haven't had a solution other than scrounge them at yard sales etc. I just found an eBay seller that has 82mm PL for $8.50. This is way cheap for these big ones. I bought a couple and they are quality made in Japan with total extinction. The eBay # is 170282710765 Normal retail on a polarizer this size is usually several times this price. They are linier polarizers and not circular polarizers which is perfect for meteorite Xpol application. Check out my Micro Vision article in the Jan 2007 Meteorite Times Cross titled Polarized Light Hand Sample Examination. The link is http://www.meteorite.com/meteorite-gallery/Micro_Visions.htm This will give you an idea of what polarizers can do in meteorite examination and you don't necessarily need a microscope. With two 82mm filters you could make a thin section viewing set. These are big enough for a standard microscope slide to fit inside the filter holder. I'm not selling any thing, I just thought some of you might like to know. Also, while you are at Meteorite Times, check out this months MV on NWA 3151 Brachinite. It has three killer shots from Bernd Pauli in wide field cross polarized light. Tom Phillips **Make your life easier with all your friends, email, and favorite sites in one place. Try it now.

[meteorite-list] Hey folks
Hi everyone - Every day when I go to www.spacer.com for space news, I see these adds for Moondust pens containing real SIMULATED Moon dust. If any of you people saved your lunar cuttings, then it would strike me that this is wide open for you. Good luck and Good hunting, E.P. Grondine Man and Impact in the Americas PS - Probably a few years from now someone will have little flat panels with the Peekskill fall video, with a piece of Peekskill mounted next to it. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
