Re: [meteorite-list] News confirmed - NASA landed on VESTA !
My *guess* is that it is probably more stones of the Eucrite-IMB that has been floating around for the last couple of years or so which also tend to be small stones. There may be more than one type of Eucrite-IMB out there though. Maybe those who have had similar material classified could chime in but I would say it needs classification to be sure though.

[meteorite-list] Pawnee meteorite lore
Hi all - I spent some time reading through Adrienne Major's book Fossil Legends of the First Americans recently. It's not too bad, and she nearly spans the two worlds, but sadly did not realize that the peoples remembered impacts, and thus failed to entirely grasp simple concepts like uktena and tlanwa. She also retells the traditions, with her intense interest in fossils coloring them, and it is tough using her book to locate the originals as they were first shared. However, that said, its a pretty good book. In the footnotes we find these two items: Besides an interest in fossils, the Pawnees were also keenly aware of meteorites, which they located and collected after observing their trajectories. Indeed, the Kansas prairie is one of the best places on Earth to find meteorites. page 377 Pawnee priests were concerned with astronomy, while Pawnee doctors dealt with earth phenomena, such as fossils. page 376 good hunting, everyone, E.P.

Its eucrite IMB becouse each sample is different. Some fragments dont have IMB and other consist in 80+% with IMB so it depends what sample I will send to lab ofcourse. It seems to me it should have broken apart and separated at that point where they connect. And if they had separated what would you call or classify the black portion as? No, I think this is zone beetween eucrite fragment that swim in a vein of hot and liquid eucrite. It happends becouse of any kind of impact or something similar.

[meteorite-list] What's Hitting Earth?
http://science.nasa.gov/science-news/science-at-nasa/2011/01mar_meteornetwork/ What's Hitting Earth? NASA Science News March 1, 2011: Every day about 100 tons of meteoroids -- fragments of dust and gravel and sometimes even big rocks - enter the Earth's atmosphere. Stand out under the stars for more than a half an hour on a clear night and you'll likely see a few of the meteors produced by the onslaught. But where does all this stuff come from? Surprisingly, the answer is not well known. Now NASA is deploying a network of smart cameras across the United States to answer the question, 'What's Hitting Earth?' Did that meteor you saw blazing through the sky last night come from the asteroid belt? Was it created in a comet's death throes? Or was it a piece of space junk meeting a fiery demise? When I get to work each morning and power up my computer, there's an email waiting with answers, says William Cooke, head of NASA's Meteoroid Environment Office. And I don't have to lift a finger, except to click my mouse button. Groups of smart cameras in the new meteor network triangulate the fireballs' paths, and special software^1 uses the data to compute their orbits and email Cooke his morning message. If someone calls me and asks 'What was that?' I'll be able to tell them. We'll have a record of every big meteoroid that enters the atmosphere over the certain parts of the U.S. Nothing will burn up in those skies without me knowing about it! In other U.S. meteor networks, someone has to manually look at all the cameras' data and calculate the orbits - a painstaking process. With our network, our computers do it for us - and fast, says Cooke. The network's first three cameras, each about the size of a gumball machine, are already up and running. Cooke's team will soon have 15 cameras deployed east of the Mississippi River, with plans to expand nationwide^2 . Cooke is actively seeking schools, science centers, and planetaria willing to host his cameras. Criteria are listed in the notes at the end of this story. In addition to tracking fireballs and their orbits, Cooke's system gives him other valuable information. It provides data on meteor speed as a function of size - and this is critical to calibrating the models we use in designing spacecraft. Meteorite hunters will reap benefits too. By determining a bright fireball's trajectory through the atmosphere, the network's software can calculate whether it will plunge to Earth and pinpoint the impact location fairly precisely. And when we collect the meteorite chunks, we'll know their source. I could be holding a piece of Vesta in my hand.^3 It would be like a free sample return mission! Opportunities like that, however, will be rare. Most meteorites fall in the ocean, lakes, forests, farmer's fields, or the Antarctic, says Rhiannon Blaauw, who assists Cooke. And the majority of those meteorites will never be found. But our system will help us track down more of them. All cameras in the network send their fireball information to Cooke and to a public website, fireballs.ndc.nasa.gov. Teachers can contact Cooke at william.j.co...@nasa.gov to request teacher workshop slides containing suggestions for classroom use of the data. Students can learn to plot fireball orbits and speeds, where the objects hit the ground, how high in the atmosphere the fireballs burn up, etc. Cooke gives this advice to students and others who want to try meteor watching on their own: Go out on a clear night, lie flat on your back, and look straight up. It will take 30 to 40 minutes for your eyes to become light adapted, so be patient. By looking straight up, you may catch meteor streaks with your peripheral vision too. You don't need any special equipment -- just your eyes. One more thing -- don't forget to check the website http://fireballs.ndc.nasa.gov/ to find out what you saw! Author: Dauna Coulter Editor: Dr. Tony Phillips Credit: Science@NASA *More Information* (1) The smart meteor network uses ASGARD (All Sky and Guided Automatic Realtime Detection) software, developed at the University of Western Ontario with both NASA and Canadian funding, to process the information and perform the triangulation needed to determine the orbits and origins of the fireballs. The Southern Ontario Meteor Network, or SOMN, composed of seven cameras, also uses the ASGARD system. (2) The cameras will be deployed in clusters of 5. One group will be spread over the Southeast US, another in the Ohio and Kentucky area (to overlap with the Southern Ontario Meteor Network, or SOMN), and another along the Atlantic coast in the NorthEast. Our hope is that at least one of the three regions will have clear skies at any given time. *Here are the criteria* that must be met for a location to be considered as a camera site: 1.

[meteorite-list] Abundant Ammonia Found in Antarctic Meteorite Aids Life's Origins
http://asunews.asu.edu/20110301_ammonia Abundant ammonia aids life's origins Arizona State University March 01, 2011 An important discovery has been made with respect to the possible inventory of molecules available to the early Earth. Scientists led by Sandra Pizzarello, a research professor at Arizona State University, found large amounts of ammonia in a primitive Antarctic asteroid. This high concentration of ammonia could account for a sustained source of reduced nitrogen essential to the chemistry of life. The work is being published in this week¹s Proceedings of the National Academy of Sciences (PNAS). The paper is titled, Abundant ammonia in primitive asteroids and the case for a possible exobiology, and is co-authored by Pizzarello, geologist Lynda Williams, chemists Gregory Holland and Jeffery Yarger, all from ASU and Jennifer Lehman of UC Santa Cruz. The finding of a high concentration of nitrogen-bearing molecules in an asteroidal environment shown by the new study is very provocative. Besides the noble gases, nitrogen is the fourth most abundant element in the Sun and the universe overall. On the Earth, it is an indispensable ingredient of the biosphere, being essential to DNA, RNA and proteins. In other words, it is necessary for life's information transfer and catalytic processes. All origins-of-life theories need to account for a sustained source of reduced nitrogen in order to make amino acids and nucleobases, said Pizzarello, who works in ASU's Department of Chemistry and Biochemistry in the College of Liberal Arts and Sciences. On the early Earth, on the other hand, the prebiotic inventory of reduced nitrogen necessary for the formation of N-containing biomolecules has been difficult to predict. The hypotheses of a reducing atmosphere had initially allowed one to envision considerable ammonia abundance as well as evolutionary pathways for the production of amino acids. However, the current geochemical evidence of a neutral early Earth atmosphere, combined with the known photochemical destruction of ammonia, has left prebiotic scenarios struggling to account for a constant provision of ammonia. An abundant exogenous delivery of ammonia, therefore, might have been significant in aiding early Earth's molecular evolution, as we should expect it to have participated in numerous abiotic as well as prebiotic reactions. It also is interesting to note that the new PNAS work was made possible by the finding in Antarctica of these exceptionally pristine, ammonia-containing, asteroidal meteorites. Antarctic ices are good curators of meteorites. After a meteorite falls and meteorites have been falling throughout the history of Earth it is quickly covered by snow and buried in the ice. Because these ices are in constant motion, when they come to a mountain, they will flow over the hill and bring meteorites to the surface.

NASA Science News March 1, 2011: Every day about 100 tons of meteoroids -- fragments of dust and gravel and sometimes even big rocks - enter the Earth's atmosphere. Stand out under the stars for more than a half an hour on a clear night and you'll likely see a few of the meteors produced by the onslaught. But where does all this stuff come from? Surprisingly, the answer is not well known. Now NASA is deploying a network of smart cameras across the United States to answer the question, 'What's Hitting Earth?' Did that meteor you saw blazing through the sky last night come from the asteroid belt? Was it created in a comet's death throes? Or was it a piece of space junk meeting a fiery demise? When I get to work each morning and power up my computer, there's an email waiting with answers, says William Cooke, head of NASA's Meteoroid Environment Office. And I don't have to lift a finger, except to click my mouse button. Groups of smart cameras in the new meteor network triangulate the fireballs' paths, and special software^1 uses the data to compute their orbits and email Cooke his morning message. If someone calls me and asks 'What was that?' I'll be able to tell them. We'll have a record of every big meteoroid that enters the atmosphere over the certain parts of the U.S. Nothing will burn up in those skies without me knowing about it! In other U.S. meteor networks, someone has to manually look at all the cameras' data and calculate the orbits - a painstaking process. With our network, our computers do it for us - and fast, says Cooke. The network's first three cameras, each about the size of a gumball machine, are already up and running. Cooke's team will soon have 15 cameras deployed east of the Mississippi River, with plans to expand nationwide^2 . Cooke is actively seeking schools, science centers, and planetaria willing to host his cameras. Criteria are listed in the notes at the end of this story. In addition to tracking fireballs and their orbits, Cooke's system gives him other valuable information. It provides data on meteor speed as a function of size - and this is critical to calibrating the models we use in designing spacecraft. Meteorite hunters will reap benefits too. By determining a bright fireball's trajectory through the atmosphere, the network's software can calculate whether it will plunge to Earth and pinpoint the impact location fairly precisely. And when we collect the meteorite chunks, we'll know their source. I could be holding a piece of Vesta in my hand.^3 It would be like a free sample return mission! Opportunities like that, however, will be rare. Most meteorites fall in the ocean, lakes, forests, farmer's fields, or the Antarctic, says Rhiannon Blaauw, who assists Cooke. And the majority of those meteorites will never be found. But our system will help us track down more of them. All cameras in the network send their fireball information to Cooke and to a public website, fireballs.ndc.nasa.gov. Teachers can contact Cooke at william.j.co...@nasa.gov to request teacher workshop

Hi Robert, I got it... Looks like a great idea... ;) I just haven't had time to reply yet.

Re: [meteorite-list] East Coast Meteor and MN Meteor 1MAR2011
Hello Dirk and Listers, I've been staring up at the sky for monthsHaven't seen s---. It seems more meteors are clobbering the East Coast than bombs fell on London during WW2. It's about G-- damn time we got a boomer out here in Nevada. One of those big ass bolides detonating and fragging and scaring the s--- out of the peasants. Boredstiff.
