HI! Have someone some blank microscope slides for thin section for sale? Could someone tell me where I can find for sale? I'm looking on ebay but I find only normal slides 1x3, but the dimensions of the thin section slides that I have are very different about 26x46mm.

Re: [meteorite-list] the next met. bulletin
I hope only this time Dr.Connolly decide to put the Lido di Venezia meteorite seen the analysis is ready from over 7 years and we have re-sent 1.5 years ago again complete. I not understand, for other ordinary material found in desert or other desert zones of the world this appear to the Met.Bullitin immediatly, when is a meteorite from Italy this take many time to appear in the met.bulletin. Another, I hope Mr.Killgore decide to inform me what is it the meteorites I have sent to him years ago to analyzed in the University, or I have to addvise the University he not work if he say is one of the responsable of the Arizona University for the meteorite analysis And no answer to emails or fax's sent to him???

[meteorite-list] The Threat from Outer Space
http://www.economist.com/world/international/displaystory.cfm?story_id=9533468 The threat from outer space Economist.com July 23, 2007 The ultimate environmental catastrophe ONE of the main weaknesses of the environmental movement has been its unfortunate predilection for using doom-laden language and catastrophic superlatives to describe problems that are serious but not immediately disastrous. But one calamity that truly deserves such a description is almost never talked about. There are tens of millions of asteroids in the solar system, and several thousand move in orbits that take them close to Earth. Sooner or later, one of them is going to hit it. Several have done so in the past. Earth's active surface and enthusiastic weather conspire to scrub the tell-tale impact craters from the planet's surface relatively quickly, but the pockmarked surface of the moon - where such scars endure for much longer - testifies to the amount of rubble floating in the solar system. Earth's thick atmosphere makes it better protected than the moon: asteroids smaller than about 35 metres (115 feet) across will burn up before hitting its surface. Nevertheless, plenty of craters exist. The Earth Impact Database in Canada lists more than 170. Fortunately, such impacts are relatively rare, at least on human timescales. Statisticians calculate that the risk to lives and property posed by meteorite strikes are roughly comparable with those posed by earthquakes. Although the chance of an impact may be small in any given year, the consequences could be enormous. The effect of an impact depends on an object's size and speed. A meteorite a few metres wide could level a city. The largest (a kilometre or more in diameter) could wreak ecological havoc across the entire globe. David Morrison, a NASA scientist, argued at a recent conference that a large meteorite strike is the only known disaster (except perhaps global nuclear war) that could put civilisation at risk. Nasa Armageddon Examples give a more visceral illustration than statistics. The Chicxulub crater, buried beneath modern Mexico, is 65m years old and 180km (112 miles) across. Some think that the ten-kilometre meteorite that created it threw so much dust into the atmosphere that it blotted out the sun and led to the extinction of the dinosaurs. In 1908 a comparatively tiny piece of space-borne rock, 30-50 metres across, exploded above Tunguska, a remote part of Siberia. The blast - hundreds of times more powerful than the atom bomb dropped on Hiroshima 37 years later - felled 80m trees over 2,150 square kilometres. Only blind luck ensured that it took place in a relatively unpopulated part of the world. Astronomers are currently trying to work out whether a 270-metre asteroid named 99942 Apophis will hit Earth in 2036 (probably not, but it would be nice to be sure). Happily for humanity, technology has advanced to the point where it is possible, in principle, to avoid such a collision. In 1998 NASA agreed to try to find and catalogue, by 2008, 90% of those asteroids bigger than 1km in diameter that might pose a threat to Earth. Any deemed dangerous would have to be pushed into a safer orbit. One obvious way to do this is with nuclear weapons, a method that has the pleasing symmetry of using one potential catastrophe to avert another. But scientists counsel caution. A nuclear blast could simply split one large asteroid into several smaller ones, some of which could still be on a collision course. Other plans have been suggested. One is to use a high-speed spaceship simply to ram the asteroid out of the way; another is to land a craft on the rock's surface and use its engines to manoeuvre the asteroid to safety. A subtler method is to park a spaceship nearby and use its tiny gravity to pull the asteroid gradually off course. For now, all such suggestions are theoretical, although the European Space Agency is planning a mission, named Don Quijote, to test the ramming tactic in 2011. These schemes offer consolation, but any effort to deflect an asteroid requires plenty of advance warning, and that may not always be available. NASA has so far catalogued only the very largest, civilisation-killing asteroids. Plenty of smaller ones remain undiscovered, and they could inflict considerable damage. In 2002 a mid-sized asteroid (50-120 metres across) missed Earth by 121,000km - one-third of the distance to the moon. Astronomers discovered it three days after the event. Comets, which originate from the outer reaches of the solar system, are faster moving and harder to track than asteroids, but carry just as much potential for catastrophe. But perhaps the biggest problem is humanity's indifference. Currently only America is spending any money on detection, and even there, politicians have other priorities. Much of the work is done by Cornell University's Arecibo radar in Puerto Rico, which is facing federal funding cuts. The telescope costs roughly $1m a year to operate.
[meteorite-list] Arizona Radio Observatory Team Discovers Supergiant Star Spews Molecules Needed for Life
ARIZONA RADIO OBSERVATORY TEAM DISCOVERS SUPERGIANT STAR SPEWS MOLECULES NEEDED FOR LIFE (From Lori Stiles, University Communications, 520-626-4402) - Monday, July 23, 2007 --- Contact information, Web sites listed at the end --- University of Arizona astronomers who are probing the oxygen-rich environment around a supergiant star with one of the world's most sensitive radio telescopes have discovered a score of molecules that include compounds needed for life. I don't think anyone would have predicted that VY Canis Majoris is a molecular factory. It was really unexpected, said Arizona Radio Observatory (ARO) Director Lucy Ziurys, UA professor of astronomy and of chemistry. Everyone thought that the interesting chemistry in gas clouds around old stars was happening in envelopes around nearer, carbon-rich stars, Ziurys said. But when we started looking closely for the first time at an oxygen-rich object, we began finding all these interesting things that weren't supposed to be there. VY Canis Majoris, one of the most luminous infrared objects in the sky, is an old star about 5,000 light years away. It's a half million times more luminous than the sun, but glows mostly in the infrared because it's a cool star. It truly is supergiant -- 25 times as massive as the sun and so huge that it would fill the orbit of Jupiter. But the star is losing mass so fast that in a million years -- an astronomical eyeblink -- it will be gone. The star already has blown away a large part of its atmosphere, creating its surrounding envelope that contains about twice as much oxygen as carbon. Ziurys and her colleagues are not yet halfway through their survey of VY Canis Majoris, but they've already published in the journal, Nature (June 28 issue), about their observations of a score of chemical compounds. These include some molecules that astronomers have never detected around stars and are needed for life. Among the molecules Ziurys and her team reported in Nature are table salt (NaCl); a compound called phosphorus nitride (PN), which contains two of the five most necessary ingredients for life; molecules of HNC, which is a variant form of the organic molecule, hydrogen cyanide; and an ion molecule form of carbon monoxide that comes with a proton attached (HCO+). Astronomers have found very little phosphorus or ion molecule chemistry in outflows from cool stars until now. We think these molecules eventually flow from the star into the interstellar medium, which is the diffuse gas between stars. The diffuse gas eventually collapses into denser molecular clouds, and from these solar systems eventually form, Ziurys said. Comets and meteorites dump about 40,000 tons of interstellar dust on Earth each year. We wouldn't be carbon-based life forms otherwise, Ziurys noted, because early Earth lost all of its original carbon in the form of a methane atmosphere. The origin of organic material on Earth -- the chemical compounds that make up you and me -- probably came from interstellar space. So one can say that life's origins really begin in chemistry around objects like VY Canis Majoris. Astronomers previously studied VY Canis Majoris with optical and infrared telescopes. But that's kind of like diving in with a butcher knife to look at what's there, when what you need is an oyster fork, Ziurys said. The Arizona Radio Observatory's 10-meter Submillimeter Telescope (SMT) on Mount Graham, Ariz., excels as a sensitive stellar oyster fork. Chemical molecules each possess their own unique radio frequencies. The astronomers identify the unique radio signatures of chemical compounds in laboratory work, enabling them to identify the molecules in space. The ARO team recently began testing a new receiver in collaboration with the National Radio Astronomy Observatory. The receiver was developed as a prototype for the Atacama Large Millimeter Array, a telescope under construction in Chile. The state-of-the-art receiver has given the SMT 10 times more sensitivity at millimeter wavelengths than any other radio telescope. The SMT can now detect emission weaker than a typical light bulb from distant space at very precise frequencies. The UA team has discovered that the molecules aren't just flowing out as a gas sphere around VY Canis Majoris, but also are blasting out as jets through the spherical envelope. The signals we receive show not only which molecules are seen, but how the molecules are moving toward and away from us, said Stefanie Milam, a recent doctoral graduate on the ARO team. The molecules flowing out from VY Canis Majoris trace complex winds in three outflows: the general, spherical outflow from the star, a jet of material blasting out towards Earth, and another jet shooting out a 45 degree angle away from Earth. Astronomers have seen bipolar outflows from stars before, but not two, unconnected, asymmetric and apparently random outflows, Ziurys
[meteorite-list] Mars Dust Storm Update - July 23, 2007
http://www.jpl.nasa.gov/news/news.cfm?release=2007-080 NASA Mars Rovers Braving Severe Dust Storms Jet Propulsion Laboratory Updated July 23, 2007 NASA's Mars Exploration Rover Opportunity sent signals Monday morning, July 23, indicating its power situation improved slightly during the days when it obeyed commands to refrain from communicating with Earth in order to conserve power. Dust storms on Mars in recent weeks have darkened skies over both Opportunity and its twin, Spirit. The rovers rely on electricity that their solar panels generate from sunlight. By last week, output from Opportunity's solar panels had dropped by about 80 percent from a month earlier. Rover controllers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., commanded Opportunity last week to go into a very low-power state and to communicate only once every three days. The rover transmitted a small amount of information today. Next scheduled transmission will be Thursday, July 26, though controllers may command Opportunity to send information on Tuesday, July 24. Meanwhile, communications from Spirit over the weekend indicated that the sky had cleared slightly at Spirit's location on the other side of Mars from Opportunity. The outlook for both Opportunity and Spirit depends on the weather, which makes it unpredictable, said JPL's John Callas, project manager for both rovers. If the weather holds where it is now or gets better, the rovers will be OK. If it gets worse, the situation becomes more complex. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] OT: Lack of CLASS FOR NWA 2749 OT: REPLY ABOUT BIG STEVE ADs
Congrats Steve, I am sure that the offers to buy are going to fly in for an NWA OC H5; at $8.00/gr (or was that 0.80 cents per gram?)that is a super bargain when many witnessed falls and US finds are much cheaper and certainly more rare than an orphan NWA that hasn`t been paired YET! Wow a BIG STEVE OFFER!! Maybe you live in another world than reality? I suggest that you find some suckers on fleabay and sell only specks; it will appear to be more rare that way. BTW: If your NWA 2749 is not yet published in the Meteoritical Bulletin perhaps it will not get the status you dream of? A committee must approve it before your dream comes truelalalalala land Enough of your blowing your own horn and wasting other`s time with your non-sense! Don`t you have a fan club by now that you can email privately? Sorry, not all of us appreciate your enthusiasm for your lack of sense.
