Re: [meteorite-list] WG: Asian falls
Martin, All, I would like to point out that the law prohibiting the approved export of meteorites from Australia, the Protection of Movable Cultural Heritage Act, was passed in 1986. 309 meteorites have been recovered, analyzed, and officially published in Australia since then, not including the relict iron recently found. Breaking statistics up by date alone can lead to deceiving conclusions. Most of the meteorites found in Australia in the past thirty years were found between 1990 and 1994, several years after the prohibitive laws had been passed. So, yes, it's true that relatively few meteorites have been found in Australia in the past decade. But no new laws were introduced around the year 2000, so logic would lead us to conclude that prohibitive export laws are not the culprit. Why, then, did rates fall so dramatically? I'm not sure. I'm guessing it was the influx of Saharan and NWA meteorites that caused market prices to bottom out. All of a sudden, a CK4 like Maralinga wasn't worth untold hundreds per gram. Stones like Camel Donga and Millbillillie have dropped to thirty or so percent of what they used to sell for -- and ordinary chondrites like Hamilton, Cook 007 and others now sell on ebay for cents per gram, instead of the few dollars or so they fetched ten or more years ago. And the subsistence wage in Australia is considerably higher than in Morocco (it takes more money to live above the poverty line). So while someone in Morocco might be able to live reasonably well if they sell their stones for a few cents per gram, the same is likely not true for someone in Australia. That's my best guess, anyways. If you go through the Meteoritical Bulletin, you'll notice that very few, if any, of the meteorites were actually found by meteorite dealers; they were found by Aussies, and they were found well after the passing of the 1986 law.

Martin, I believe Canadian export practice is now working not only because the rules were well thought out but also because the people in charge are level headed and thoughtful. Thanks Monica and thanks Ian! The crater forming meteorite is Whitecourt. A new iron find which fell about 1000 years ago and left a small crater in Northern Alberta. Cheers!

Re: [meteorite-list] WG: Asian falls
logic would lead us to conclude that prohibitive export laws are not the culprit. My personal belief is that this is correct. Export laws can work and Canada is an example of that. The problem here is not the federal export laws but the individual state laws (W.A., S.A. N.T. in particular) which grant ownership of any meteorites to the state. Basically it seems that people finding new material now just don't report it as they will not be able to keep it. Get rid of those laws and I guarantee the official find rate will steadily rise.

One was Tuesday: Dec 28th @ 6:45 - 6:50 the other was Wednesday: Dec 29th @ 8:30 The one tuesday night was spotted all up and down the east coast and has resulted in close to 100 AMS reports.

Borda News-Post Staff It wasn't a bird. It wasn't a plane. It wasn't even ... well, you know, but there was something that zipped across the evening sky at about 6:50 p.m. Wednesday and a number of area folks say they saw it. I tell you what, the hair stood up on the back of my neck, said Al Labrush, a veteran meteorite watcher and collector. It was frightening. Labrush said he was standing near Danielle's restaurant downtown when he caught sight of something that looked to be about 1,500 feet away. I heard this sizzling behind me. ... I turned and looked: This huge meteorite came. ... It was throwing off sparks and chunks, Labrush said. I'm into meteorites -- every time they call for meteor showers, I'm out. I very seldom get scared -- (but) I never want to see another one like that. Steve Lawrence saw it, too. Lawrence was driving home on Old Kiln Road when he saw the bright object in the northern sky, like a fireball, through the passenger side window. Three white flashes erupted, lighting up the night like daylight for an instant, and then it all seemed to disintegrate, he said. Night turned to day, Lawrence said. The flash was like heat lightning. Sean Dennison saw it, too -- from Hagerstown. Dennison, who works with Lawrence, was walking from his house to his car when he saw it. It was so unusual that he went back inside to tell his wife, before heading out to play racquetball. He heard Lawrence talking about the bright light Wednesday and chimed in. I saw the same thing, said Dennison, who compared the white brightness to burning magnesium, and the object moved slower than a falling star. A burst of sparkles, like fireworks, concluded the scene, he said. Lawrence said he watched a plume of smoke hanging in the night sky for 20 minutes. Robert Gutro, a NASA deputy news chief, said he took a call from a woman he did not know who telephoned Tuesday to report what she had seen. She was kind of panicked, Gutro said. She described the bright object moving across the sky, and it broke up into pieces, he said. A spokesman for the North American Aerospace Defense Command said NORAD did not report tracking anything, which rules out so-called space junk, such as out-of-commission satellites. Frederick County Emergency Communications reported no calls about it. If it was a meteor, it likely left a trail of debris, said expert John Wasson at the University of California at Los Angeles. He said it sounded like a meteor is probably what people saw. Wasson predicted that meteor hunters such as Mike Farmer of Tucson, Ariz., would be on the trail before anyone else. Farmer said he surely would be. Normally, I would jump on the plane and come out, Farmer said when reached by telephone. But Wednesday he was preparing to go to the Middle East on an expedition. Farmer was not aware of any meteoric activity here, but based on the accounts of Tuesday's event, he said he would have people look into it. Lawrence said he had the unsettling feeling that whatever it was fell less than a mile from his house, and he planned to look for evidence.

Re: [meteorite-list] WG: Asian falls
Hi Jason, some of the federal laws in Australia were even earlier in place. The find numbers, correct me if I'm wrong, were produced mainly by official expeditions, two times Euromet (one of them at least hopelessly unsuccessful Mundrabillas, Millbillillies, three OCs - stuff in a quantity a meteorite dealer would charge you today with 15-20k$) and one carried out by the school of mines. 15 published new finds for a whole continent with deserts, where the past proved, that they are very productive for meteorite finds - and that in THE decade, where the big harvest took place in the deserts of the African, Asian, and North-American continent, is very unsatisfying, especially in a country of such a long and in former times remarkable meteorite tradition. The problem is, that since the 1990ies, no serious meteorite expedition wasn't carried out anymore by universities there, as well as the basic work (see the 500 unclassified finds) was neglected. So the Australian meteoricists fall short regarding the special meaning and status, the Aussie meteorites are given in Australian legislation. Consequently this legislation isn't tenable anymore. How meteorites are found, I think everyone of us here on the list knows, as well as those involved in Australian projects, at least partially, do know. Therefore I allow myself to criticize the legal situation and the efforts undertaken there. Some blogs of the expeditions there, you have on internet. A handful people, for a few days in the desert, hence less professional than any of the amateur hunters. The fireball network, I'm allowed to criticize, because it is partially financed by my tax-money, I'm generating with meteorite sales. The costs and the equipment, the goals and the predicted find rates, of this project, you'll find on internet. They admit there, and the find area and the size of the covered area are almost the best condition, one can have for meteorite finding, they admit there, that they even weren't looking for all the droppers, they were able to narrow down. Here in Europe we have fundamentally different experiences and methods with our fireball network. We learned, that whenever possible, the help and the manpower of amateur hunters has to be used, to find the stones, which the cameras had documented. Therefore the data and predicted fall areas are open to everyone. If you take Neuschwanstein for instance - hundreds of people were hunting for three years in a difficult terrain, and if you take your North American showers, we have it always here on the list, there you know, what for a large number of participants and what time-spans are necessary to generate the resulting tkws. In Australia, you have an easy accessible flat terrain with less vegetation than here in Europe, the efforts to spend to find the droppers would be much lower than here - but even that isn't done there. And keeping in mind, that the camera stations here in Europe are maintained by volunteer amateurs, cost-free, as well as the hunts are done by volunteers cost-free - and finally if I think, that the large European fireball net costs only a few thousands per year, but the small Australian net a couple of hundreds of thousands, then I can express my doubts, whether my tax-money (if I'm not allowed to use it for maintaining my yacht, my castle, my Bentley-collection, my riding horses, like almost all other meteorite dealers) couldn't be used more effectively if used for meteoritical purposes, as long as the Aussie-network methodically isn't running lege artis. The problem is, that the Australians, other than in other countries, can't avail themselves of the enormous, but free, help of amateur hunters and trained expert private hunters. Because with their laws, they created - even independently from individual mentality - legal artificial obstacles to do so. And these laws, see also the federal laws there, are an anachronism from those times, when there were still so few finds a year, that it could have been worth to try to go the way of disappropriation and cutting personal rights. Well, it turned out, and that very soon, to have been a misjudgement. I object to the Aussie meteoricists and those involved, to adhere still today to that misjudgement by all means, ignoring the experiences and stats collected over the recent decades in their own country as well as in other countries. Monetary values, Jason, I don't believe them to be an argument. At current prices it wouldn't make sense for a nomad to bend down to pick up an weathered OC. And you and your colleagues, the sparetime hunters in USA, who generate so many new finds - and there I think we're together, to find an achondrite, to find a Martian or something like Sonny's CM1 you have to generate large find rates - they are doing it because of their enthusiasm - economically it isn't lucrative. And btw. the argument doesn't hold water in the Aussie case, note that the rights of ownership aren't trimmed for the Australian
Re: [meteorite-list] Crystals in Lunar Meteorites...?
Greg; Most lunar rocks are impact breccias - rocks made up of bits and pieces of older rocks. The pieces are called clasts and they may be suspended in a matrix of crystallized impact melt, glass, or shocked-compressed smaller clasts. Big clasts are fragments of rocks. The smaller clasts are typically single mineral grains. It's not uncommon to see clasts of breccias in breccias in breccias.

Dear Friends, I believe that Derek and Hazel have been taking a well earned Christams season holiday with family. Its been a lot of work to pick up the magazine mid-stride, along with all of our regular work loads, but I'm confident we'll be able to take care of all of your subscription support and get the magazine out on time from here forward. I really appreciate all of your patience and support during this transition. It's hard to tell you much about August issue, since it was before we were involved, but we will do our best to get everyone taken care of. On another note, if you have new feature or article ideas that you would like to propose or contribute, please let us know. This is magazine is created by the meteorite community for the meteorite community, and we are enthusiastic about having your input and contributions. We are collecting May issue articles now, so let us know if there is something you would like to write. All the best to each of you, and I hope that you all have a wonderful New Years Eve.

Re: [meteorite-list] NASA finds extra-terrestrial amino-acids in Sudan meteorites
Hi Mike and List, Have been meaning to post a reply about the article link Mike posted: http://www.digitaljournal.com/article/301636 I assume they are talking about Almahata Sitta. I had not heard this before. Yes, Almahata Sitta is right. As we all know, ET amino acids have been found in plenty of carbonaceous meteorites, perhaps most famously within Murchison. So I was curious to find out what was so special about finding them in carbon-rich 2008 TC3 (Almahata Sitta). A quote from the article: Amino-acids have been found in carbon-rich meteorites before but this is the first time the acid substances have been found in a meteorite as hot as 2,000 Fahrenheit (1,100c). This naturally heated hot rock should have obliterated any form of organic material, reports National Geographic. Daniel Glavin, an astro-biologist at NASA's Goddard Space Flight Centre in Maryland said, Previously, we thought the simplest way to make amino acids in an asteroid was at cooler temperatures in the presence of liquid water, this meteorite suggests there's another way involving reactions in gases as a very hot asteroid cools down. So the obvious question to ask is why anyone thinks that the interior of 2008 TC3 was ever heated up to 1100 C? Sure, the *surface* of the asteroid got very hot when it entered earth's atmosphere, but how is that different from Murchison or any other meteorite-generating fall? The interior of 2008 TC3 should never have been above freezing. So something must be missing from the article to explain why they believe Almahata Sitta's interior got so hot. About all I can come up with is that they assumed 2008 TC3 was a rubble pile (almost certainly true given the range of petrology), and that it fragmented into tiny pieces very high in the atmosphere while still moving at cosmic velocity. Instead of heat from ablation only affecting the outer centimeter or so of the surface of a 4-meter monolithic rock, all the individual fragments got the blast treatment. I still don't buy it, though. Small fragments decelerate so rapidly that there wouldn't be time to heat up the interior of even a 1 diameter rock.

Re: [meteorite-list] NASA finds extra-terrestrial amino-acids in Sudan meteorites
This raises some very interesting question. If the interior (core) of the smaller stones from smaller meteorite falls such as Murchison, Tagish Lake, Allende, Ash Creek, Mifflin, or any meteorite fall for that matter, are still frozen during entry and upon impact, then would it be a stretch of logic to assume a larger iron mass, such as Canyon Diablo, which was estimated to be 50 meters wide, would also still have a frozen core upon impact? After all it did hold probably most of it's cosmic velocity, meaning it was incandescent for just a few seconds at most, right? Even when you consider iron conducts heat much faster and more efficiently than stone, could such a large mass heat all the way to the core in just a couple few seconds?

Even when you consider iron conducts heat much faster and more efficiently than stone, could such a large mass heat all the way to the core in just a couple few seconds? I wouldn't think so. As the outside of a meteoroid is melted upon atmospheric entry, melted material is constantly being sloughed off along with the heat that caused the melting. As the melted material sloughs, it exposes fresh material that is still frozen. This process continues until the meteoroid hits the ground, burns up completely or slows sufficiently til it no longer causes incandescence and begins to air cool.

[meteorite-list] Asteroid Itokawa Sample Return
http://science.nasa.gov/science-news/science-at-nasa/2010/30dec_samplereturn/ Asteroid Itokawa Sample Return NASA Science News Dec. 29, 2010: The Japanese Aerospace Exploration Agency's Hayabusa spacecraft has brought home to Earth tiny pieces of an alien world - asteroid Itokawa. It's an incredible feeling to have another world right in the palm of your hand, says Mike Zolensky, Associate Curator for Interplanetary Dust at the Johnson Space Center, and one of the three non-Japanese members of the science team. We're seeing for the first time, up close, what an asteroid is actually made of! He has good reason to be excited. Asteroids formed at the dawn of our solar system, so studying these samples can teach us how it formed and evolved. Hayabusa launched in 2003 and set out on a billion kilometer voyage to Itokawa, arriving a little over two years later. In 2005, the spacecraft performed a spectacular feat -- landed on the asteroid's surface^(1) . The hope was to capture samples from the alien world. But there was a problem. The projectiles set to blast up dust from the surface failed to fire, leaving only the particles kicked up from landing for collection. Did any asteroid dust made it into the collection chamber? Zolensky and other eager scientists, with eyes riveted skyward, watched the answer plunge back into Earth's atmosphere at 27,000 miles per hour on the night of June 13th, 2010. Hayabusa's main bus shattered over the Australian outback during reentry, and the intact sample return capsule drifted to Earth via parachute. We were mesmerized, says Zolensky. As we waited for it to land, no one even moved. But the waiting was only just beginning. Because attempting retrieval of the capsule in the dark was too dangerous, he spent a sleepless night before getting a closer look. I was one of the first people to board the helicopter that flew to the landing site the next morning. And I was the first person to walk up to the capsule. He had to stop within 10 feet of it. More waiting. I watched the retrieval team recover it. They wore face masks and gloves and blue padded suits. They had to disable the unexploded parachute release charges, and that was pretty nerve wracking. Then they picked up the capsule oh so carefully and placed it in a box. The precious cargo was flown via charter jet to Japan for analysis. Guess who was waiting for it when it arrived? I was ready to work, says Zolensky, who along with fellow team member Scott Sandford of NASA Ames Research Center had traveled to Japan for the opening. The first results were disheartening. When we scanned the capsule with a modified CAT scan, there appeared to be nothing inside. Next, Japanese members of the team painstakingly dismantled the capsule, piece by piece. They had to use a micromanipulator to avoid contamination, and the process took months. More waiting. Once we got inside the capsule, we could see dust on the interior walls. I thought to myself, 'we've got asteroid dust here!' But there was still a possibility the contents could be contamination from launch or reentry and landing. The next step was to remove and analyze the particles -- another agonizingly slow process, and more waiting. The particles are each smaller than the diameter of a human hair. We finally used a Teflon spatula to sweep out a large number of tiny particles. Though most of the particles are still in the capsule, the team has removed and analyzed 2000 of them with an electron microscope. And? At least 1500 of them are from the asteroid! We're seeing pieces of another world. It looks like a very primitive type asteroid. We'll tell you more in March at the 2011 Lunar and Planetary Science Conference in Houston. This is only the third time ever that samples of a solid extraterrestrial body have been brought back to Earth. The Apollo astronauts and Soviet Luna robots were first - they brought us samples of moondust. And NASA's Stardust spacecraft returned samples of comet Wild 2 in 2006. The Japanese people are thrilled, and so are we. The emperor even requested a personal tour of the capsule. This is their Apollo mission. They're showing us all a new world!

Re: [meteorite-list] NASA finds extra-terrestrial amino-acids in Sudan meteorites
Rob, Marc sent me this response after I posted the article: Yeah, apparently de novo synthesis. Hot, carbon-rich gases in the ureilite formed a small amount of amino acids in the meteorite as it cooled. My bet is that it happened on metal surfaces which acted as a catalyst, and it's not all that surprising. All you need is an appreciable amount of nitrogen in the source gas and you should get a little bit of everything as it cools. I got the impression from the article / marc that the heat happened a long time ago during the meteorites original formation or metamorphose and not during its atmospheric entry.
