[meteorite-list] NWA 6694 (was: ad- offering for sale a killer eucrite breccia like none other!)
Hi Edwin! Great new addition to the world --- and I'm with you in mind and body on the medical issues, can't say enough ... Godspeed and all our prayers and positive thoughts be with you! On the Eucrite, Wow, it is so highly polished it sort of loses me to compare to my other stone age polished specimens: Nuevo Laredo? Igdi? NWA 3368? My cute little Stannern slice isn't so nicely polished, but might even fit the bill! Do you see something different in the matrix? I plead ignorance on how breccias could be evaluated, but speaking a little about my intrinsic fancies yours would be a great candidate to do a size distribution of included chunks compared to others and something would be learned from that, though I'm not sure what it would be, it would probably be very enlightening!

Greetings list Members! Writing to introduce what I believe to be one of the wildest and most beautiful eucrites ever to fall to Earth. The pictures attached are of a center slice from this single beautiful mass. The slice weighs 121 grams. Slices from this stone range from 50 grams to 145 grams. We’ve also had three thick slices cut for museum curation. Last month Marlin Cilz and his lovely wife Debbie came to Lake Oswego for a visit during their vacation travels throughout the Northwest. While they were here visiting we opened up the vault and went through a number of stones and irons that show cutting potential. Among other items Marlin talked me into slicing and polishing a large piece of our “Super Green” NWA 6693 the pyroxenite. In Tucson this year I bought a large oriented achondrite. It was a huge gamble and a high priced purchase. But it was one of those times when instincts told me that it was something special. I really should not have made the investment but the stone was so beautiful that I figured that if it turned out to be an HED instead of planetary that I could at least maybe get the investment back by selling the oriented stone whole. We donated a large fragment taken from an already broken surface (78 grams) to UCLA for classification. The stone was classified as a eucrite (NWA 6694). This seemed to feel like a bit of a letdown. Now the vault was home to a very pretty, oriented, expensive, loaf of bread. Well, Marlin looked at this not so little gem and said; “why don’t you let me take a single cut off this side of the stone where it is already broken and it will clean up the stone, give you a good look at the inside and you can still sell the whole thing if that’s what you decide you want to do. A week later we were talking on the phone and while talking about other pieces Marlin was cutting for me I said “hey Marlin, how about just cutting the end off of that stone and then send me a picture of the cut face. He did that and when he emailed the picture it was one of those moments that one remembers forever, a definite Kodak moment. My favorite meteorite feature has always been breccia. I remember getting week in the knees the first time I saw Chico at UNM and the first time I saw Abee. I could not be happier to get to share this gorgeous meteorite with all of you. We are selling it and there are roughly twenty slices. So please feel free to contact me or Patrick off list for sizes and prices and pictures. Just minutes ago I got the long awaited phone call from my neurosurgeon’s office telling me that my back surgery is scheduled for next Tuesday September 20th. So this rock truly is a gift from Heaven. Hopefully it will help pay the medical bills. I also want to take this opportunity to publicly thank Darryl Pitt for all of his support and knowledge regarding this pending surgery and everything leading up to this time. I never dreamed that someone could talk me through the pain like Darryl has done. Instead of feeling like I am falling apart, Darryl has helped me to feel like this is just part of the program. Darryl has given me more answers and information than any ten doctors could have. He has been through exactly the same problem and repair. May the Heavens bless Darryl by dropping loads of gorgeous meteorites nearby. Not on him but nearby! Thanks man.

Re: [meteorite-list] Slightly OT: UARS decay strategy
Rob Matson wrote: A third alternative would have been to let the orbit naturally decay to a lower altitude before doing that burn. The advantage of this approach is that once the orbit is very low (as it is now), that final burn can push perigee so low that reentry is guaranteed half an orbit after the burn. This allows spacecraft controllers to choose the reentry location judiciously (e.g. over the South Pacific Ocean). By burning years early as they did, they sacrificed the ability to choose the reentry location. The problem here is, that it would have taken 30+ to 40+ years for UARS to naturally decay to a suitable altitude for such a burn. This would have meant they would be obliged to keep the satellite operational for 40+ years. Apart from questions whether the satellite will not fail before that time (I am quiet sure it wasn't designed with 40+ years in mind), for a science satellite that is financially impossible to do. Why does it need to be kept operational for these 40+ years in this case? The point is that without active maintenance, the satellite will start to lose attitude control quickly, pointing wildly to all places as it starts to tumble. Which means its receiver antennas could no longer point to earth at the moment, 40 years ahead, you want to contact it. But a bigger issue is the fuel in the tanks. Without active maintenance, the fuel will freeze in the tanks. Once that happens, it becomes impossible to use the engines for a deorbit boost. UARS is not the only thing currently coming down by the way. In about a year, a 1.5 tons malfunctioned Japanese spy satellite (IGS 1B) will come down in an uncontrolled re-entry as well. That sat does still have some fuel onboard, unlike UARS, which is an added risk. UARS is a nice bright object easily seen by the naked eye during a pass.

Congrats on that nice looking breccia! Breccias are my favorites, esp. polymicts. It's like having different stones within a stone. Reminds me alot of DaG 400, except more clast laden. One of the few neat interesting examples of how eucrites can look so lunar. e.g. (NWA 6072 -- NWA 482) (NWA 5234 -- NWA 5000) and now: (NWA 6694 -- DaG 400) any others?

[meteorite-list] Astronomers Plan Last Look at Asteroid 1999 RQ36 Before OSIRIS-REx Launch
FOR IMMEDIATE RELEASE FROM THE UNIVERSITY OF ARIZONA Sept. 13, 2011 This story and photos are online at: http://uanews.org/node/41796 . Contact information follows this story. Astronomers Plan Last Look at Asteroid Before OSIRIS-REx Launch Every six years, asteroid 1999 RQ36 nears the Earth - by cosmic standards - and researchers are launching a global observation campaign to learn as much as possible in preparation for the OSIRIS-REx, the first U.S.-led mission to bring back a sample of pristine asteroid material. Astronomers working on the U.S.' first asteroid-sample return mission - the NASA mission named OSIRIS-REx - have begun a months-long observing campaign that is the last chance to study their target asteroid from Earth before the OSIRIS-REx spacecraft launches in 2016. OSIRIS-REx is a quest to bring back to Earth a good-sized sample of an asteroid unaltered since solar system formation - a sample that very well could contain molecules that seeded life. Discovered in 1999, the OSIRIS-REx target asteroid, designated 1999 RQ36, nears Earth once every six years. During the 2011 closest approach in early September, it will be 10.9 million miles (17.5 million kilometers) away. In 1999, closest approach was 1.4 million miles (2.3 million kilometers). Six years sets the whole cadence for our mission, said Dante Lauretta of the University of Arizona Lunar and Planetary Laboratory, deputy principal investigator for the OSIRIS-REx mission. The next chance for ground-based telescopes to see this asteroid will be in 2017, when it again nears Earth. Our spacecraft performs a gravity-assist at this time, giving it the kick it needs to rendezvous with the asteroid in 2019-20. The next chance for ground-based astronomy is 2023, the year the spacecraft returns a sample of the asteroid to Earth. 1999 RQ36 last attracted astronomers' attention in 2005, when it passed 3.1 million miles (5 million kilometers) from Earth and appeared 30 times brighter than it does this year. In 2005, Carl Hergenrother of the UA Lunar and Planetary Laboratory was searching with the 61-inch Kuiper telescope on Mt. Bigelow north of Tucson for exciting targets for the proposed asteroid sample-return mission. He observed 1999 RQ36. Looking at my data, I saw this was a B-type asteroid, which is carbonaceous and related to unusual outer main-belt asteroids that act like comets by outgassing volatiles, Hergenrother, who heads the OSIRIS-REx asteroid astronomy working group, said. After a quick search of the scientific literature, which turned up nothing on the object, he did a Google search. Jackpot. Astronomers had been observing this asteroid, just not formally publishing about it, Hergenrother said. Their results were sitting on their personal Web pages. They had radar images of it, visible and near-infrared observations, confirmed it was a B-type (bluish) asteroid, got a pretty good light curve and a rotation period, although the rotation period was wrong. Michael Drake of the UA Lunar and Planetary Laboratory, principal investigator for OSIRIS-REx, urged Josh Emery, one of Drake's former students, now of the University of Tennessee and a co-investigator on OSIRIS-REx, to observe 1999 RQ36 with the Spitzer Space Telescope. Emery won the telescope time, providing first observations of the asteroid at thermal infrared wavelengths. Coming out of 2006-07, 1999 RQ36 was probably the best-studied near-Earth asteroid out there that hadn't already been visited by a spacecraft, Hergenrother said. We lucked out in that not only is this an asteroid that's relatively easy to get to, it is extremely interesting, exactly the kind of object that we want for this mission. The international team of astronomers collaborating in the fall 2011-spring 2012 observing campaign for 1999 RQ36 have time or are applying for time on a network of telescopes operating in Arizona, the Canary Islands, Chile, Puerto Rico and space. The new observations will not only influence mission planning and development, but will directly address two key OSIRIS-REx mission goals, Lauretta said. One goal is to check results from ground-based observations against results from OSIRIS-REx spacecraft observations that will be made in 2019-20 as the spacecraft circles the asteroid for about 500 days. Another goal is to measure a slight force called the Yarkovsky effect to better understand the likelihood that potentially hazardous near-Earth asteroids, such as 1999 RQ36, will strike our planet, and when. # # # LINK: The University of Arizona Lunar and Planetary Laboratory: http://www.lpl.arizona.edu CONTACTS: Dante S.

[meteorite-list] NASA Announces Design For New Deep Space Exploration System
Sept. 14, 2011 David S. Weaver Headquarters, Washington 202-358-1600 david.s.wea...@nasa.gov Michael Braukus/J.D. Harrington Headquarters, Washington 202-358-1979/5241 michael.j.brau...@nasa.gov/j.d.harring...@nasa.gov RELEASE: 11-301 NASA ANNOUNCES DESIGN FOR NEW DEEP SPACE EXPLORATION SYSTEM New Heavy-lift Rocket Will Take Humans Far Beyond Earth WASHINGTON -- NASA has selected the design of a new Space Launch System that will take the agency's astronauts farther into space than ever before, create high-quality jobs here at home, and provide the cornerstone for America's future human space exploration efforts. This new heavy-lift rocket-in combination with a crew capsule already under development, increased support for the commercialization of astronaut travel to low Earth orbit, an extension of activities on the International Space Station until at least 2020, and a fresh focus on new technologies-is key to implementing the plan laid out by President Obama and Congress in the bipartisan 2010 NASA Authorization Act, which the president signed last year. The booster will be America's most powerful since the Saturn V rocket that carried Apollo astronauts to the moon and will launch humans to places no one has gone before. This launch system will create good-paying American jobs, ensure continued U.S. leadership in space, and inspire millions around the world, NASA Administrator Charles Bolden said. President Obama challenged us to be bold and dream big, and that's exactly what we are doing at NASA. While I was proud to fly on the space shuttle, tomorrow's explorers will now dream of one day walking on Mars. This launch vehicle decision is the culmination of a months-long, comprehensive review of potential designs to ensure the nation gets a rocket that is not only powerful but also evolvable so it can be adapted to different missions as opportunities arise and new technologies are developed. Having settled on a new and powerful heavy-lift launch architecture, NASA can now move ahead with building that rocket and the next-generation vehicles and technologies needed for an ambitious program of crewed missions in deep space, said John P. Holdren, assistant to the President for Science and Technology. I'm excited about NASA's new path forward and about its promise for continuing American leadership in human space exploration. The SLS will carry human crews beyond low Earth orbit in a capsule named the Orion Multi-Purpose Crew Vehicle. The rocket will use a liquid hydrogen and liquid oxygen fuel system, where RS-25D/E engines will provide the core propulsion and the J2X engine is planned for use in the upper stage. There will be a competition to develop the boosters based on performance requirements. The decision to go with the same fuel system for the core and the upper stage was based on a NASA analysis demonstrating that use of common components can reduce costs and increase flexibility. The heavy-lift rocket's early flights will be capable of lifting 70-100 metric tons before evolving to a lift capacity of 130 metric tons. The early developmental flights may take advantage of existing solid boosters and other existing hardware. These flights will enable NASA to reduce developmental risk, drive innovation within the agency and private industry, and accomplish early exploration objectives. NASA has been making steady progress toward realizing the president's goal of deep space exploration, while doing so in a more affordable way, NASA Deputy Administrator Lori Garver said. We have been driving down the costs on the Space Launch System and Orion contracts by adopting new ways of doing business and project hundreds of millions of dollars of savings each year. NASA elected to initiate a competition for the booster stage based on performance parameters rather than on the type of propellant because of the need for flexibility. The specific acquisition strategy for procuring the core stage, booster stage, and upper stage is being developed and will be announced at a later time.

[meteorite-list] Oum Rokba (H5)
A question for those of you who may have visited this strewn field: In September of 2000, several hundred chondritic stones with a total known weight of around 100 kilos were exported out of Morocco. All of these stones were found by a Berber native turned meteorite hunter a few kilometers from an Oasis named Oum Rokba. Does anyone have the coordinates for that Oasis? I'm not sure if this oasis is in Maroc or in Western Sahara, so how do I go about finding these coordinates? -- Bob V. __ 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] Sundiving Comet
It's always great to hear of a new comet we can see, but SOHO's been cranking them out every week, especially these neverending Kreutz fragment stream like the one today, and there's not much to observe except online. It's getting harder to be excited for discoveries that one guy makes and then someone else looks at the same picture 15 seconds later an sees the same thing. I am sure it is exciting for the discoverers, but: For those who still like to observe things with their own eyes through glass, the thrill I'd recommend the newest bright SWAN Comet discovered by Rob Matson a couple weeks ago. For most of our latitudes, the comet will be visible doing its thing with the Virgin (Virgo) all night at almost the 10th magnitude, which is decent enough for a small-medium sized telescope. Plus Rob is a list member! It's C/2011 Q4 if you are looking it up...

[meteorite-list] ad-NWA 6694 eucrite price
Hello Fellow list members. After the huge response to our release of the new eucrite breccia NWA 6694, Patrick and I had a serious discussion based on all of the collectors and scientists who are strapped by a tight budget controlling their purchase decisions. We calculated the cut and polish loss and the cost of the original mass. We have decided to offer this wonderful meteorite for just a little over our cost in order to get this beautiful meteorite into more collections. So for all of those who have already committed to a slice and for those who have inquired about the sizes and price, we are selling 6694 in all sizes for $20.00 per gram. Patrick will soon have a picture page on our web site etmeteorites.com and also he will list some slices on Ebay with this same starting price. As said earlier there are roughly 20 slices, 2 thick end cuts and four thick center slices for museums or for future cutting. I will have to break down and send some material off for thin sections as under magnification it is beyond description. There have been a large number of requests for very small slices so we may decide to break up slices if that is what people want. We also had Marlin slice up a big piece of NWA 6693 Super Green and Marlin Cilz did a fantastic job of polishing these slices. Were only asking $5.00 dollars more per gram to cover the cut loss on these. Also, Patrick will be listing gorgeous thin slices of our new howardite and small partial slices of Klamath Falls Oregon the size of postage stamps and smaller for the same price per gram because there was very little cut loss or prep charge from Marlin for his top shelf workmanship on this rare Oregon iron.

Re: [meteorite-list] [Meteorites] do have a question. how many people would call it...
Well, if it is your intention to have these used as educational materials, then you would want to present these in the most naturial way possible. If you want to make a quick buck, then by all means, mess them up with oil. For the sake of the students who will benifit from these kits, stick to a method that will stick in their minds as outstanding teaching aids. I do a lot of outreach, using my collection for teaching aids. I can tell you from firsthand experience that natural is by far the prefered way.

[meteorite-list] Experiments and Observations on certain stony and metalline Substances, which at different Times are said to have fallen on the Earth by By Edward Howard
Hello Listers, I am always doing research on meteorites and I found a great paper by Edward Howard written in 1802. This paper is about Siena, Wold Cottage and Benares meteorite falls and the similarities that these three stones have in common. Down below is an introduction to the paper and at the end will be a link to the 45 page PDF file. Have fun Experiments and observations on certain Stony Substances which, at different times, are said to have fallen on the Earth also on various Kinds of native Iron. By Edward Howard, Esq. F. R. S. Read February 25, 1802. The concordance of a variety of facts seems to render it most indisputable, that certain stony and metalline substances have, at different periods, fallen on the earth. Whence their origin, or whence they came, is yet, in my judgment, involved in complete obscurity. The accounts of these peculiar substances, in the early annals, even of the Royal Society, have unfortunately been blended with relations which we now consider as fabulous ; and the more ancient histories of stones fallen from heaven, from Jupiter, or from the clouds, have evidently confounded such substances with what have been termed Ceraunia, Bcetilia, Ombria, Brontia, c. names altogether unappropriate to substances fallen on our globe* Indeed some mislead, and others are inexpressive. The term Ceraunia, by a misnomer, deduced from its supposed origin, seems, as well as Boetilia,* to have been anciently used to denote many species of stones, which were polished and shaped into various forms, though mostly wedge-like or triangular, sometimes as instruments, sometimes as oracles, and sometimes as deities. The import of the names, Ombria, Brontia, c. seems subject to the same uncertainty. In very early ages, it was believed, that stones did in reality fall, as it was said, from heaven, or from the gods ; these; either from ignorance, or perhaps from superstitious views, were confounded with other stones, which, by their compact aggregation, were better calculated to be shaped into different instruments, and to which it was convenient to attach a species of mysterious veneration• In modern days, because explosion and report have generally accompanied the descent of such substances, the name of thunderbolt, or thunderstone, has igno» rantly attached itself to them ; and, because a variety of sub« stances accidentally present, near buildings and trees struck with lightning, have, with the same ignorance, been collected as thunderbolts, the thunderbolt and the fallen metalline substance have been ranked in. the same class of absurdity. Certainly, since the phenomena of lightning and electricity have been so well identified, the idea of a thunderbolt is ridiculous. But the existence of peculiar substances fallen on the earth, I cannot hesitate to assert; and, on the concordance of remote and authenticated facts, I shall rest the assertion. Mr. King, the learned author of Remarks concerning Stones said to havefallenfrom the Clouds, in these Days, and in ancient Times, has adduced quotations of the greatest antiquity, descriptive of the descent of fallen stones ; and, could it be thought necessary to add antique testimonies to those instanced by so profound an antiquarian, the quotations of Mons. Falconet, in his papers upon Boetilia, inserted in the Histoire des Inscriptions et Belles- Lettres;* the quotations in Zahn's Specula Pbysico-matbematica Historiana ;-f the Fisica Sotterranea of Giacinto Gemma; the *** From the external characters, and from his analysis, the Professor considers the stone of Ensisheim to be argillo-ferruginous ; and is of opinion that ignorance and superstition have attributed to it a miraculous existence, at variance with the first notions of natural philosophy.* The account next m succession is already printed in the' Transactions of the Royal Society ; but cannot be omitted, as it immediately relates to one of the substances I have examined. I allude to the letter received by Sir William Hamilton, from the Earl of Bristol, dated from Sienna, July isthj 1794. In u the midst of a most violent thunder-storm, about a dozem stones, of various weights and dimensions, fell at the feet of u different persons, men, women, and children. The stones are u of a quality not found in any part of the Siennese territory ;.: they fell about eighteen hours after the enormous eruption of '* Mount Vesuvius; which circumstance leaves a choice of dif~ Acuities in the solution of this extraordinary phenomenon, Either these stones have been generated in this igneous mass* of clouds, which, produced such, unusual thunder ; or, which is; equally incredible, they were thrown franr Vesuvius, at a* distance of at least 250 miles; judge then of its? parabola;. The philosophers here incline to the first solution. I wish u much, Sir, to know your sentiments. My first, objection was u to the fact itself; but of this there are so many eye witnesses,, it seems impossible to
[meteorite-list] Green Fireball in Tempe, AZ.
Hi list. I just went for a quick lap around my apartments at McClintock and University here in Tempe. I started at approx 7:45pm GMT and while I was running south I saw a vibrant green fireball streak, break up and then it went dark. Unfortunately I wasn't close enough to hear a sonic boom but I did hear a very soft pop like a bottle rocket far away. It appeared to be 25 degrees West of South and was about 20-30 degrees from the horizon. It's was moving fairly slow so I assume it was far south. Can someone check Doppler? It must have had a better sighting further South like in Casa Grande or Tucson.

G'Day List Confirming Erik's and Count's sighting. We just got a call from Taryn, Kat's daughter. She was driving on Pahrump Valley Blvd heading South in the town of Pahrump. The light was not very high in the sky about 35 - 40 degrees. It was bright green and looked like a firework. She was able to look at it for at least 5 seconds as it was heading East and South to Las Vegas. No sonic boom was heard. Many other people in town also saw this.

[meteorite-list] NWA 6694 / Abee
Hello List, Several list members brought it to my attention that the last 3 images in Edwin's photo album are of Abee, not NWA 6694. My mistake. I should've figured it out when I noticed the 'weathering' effect was not evident in the first images of the hand specimen, '6694, only the last 3 images of the big slab of Abee. I didn't see any comments on this weathering effect seen in clasts of the Abee, can anyone explain what's going on there? Having not ever seen a piece of it in person it's hard to tell exactly what I'm looking at. Now that I know it's an EH chondrite I'm wondering if the high metal is somehow causing the effect. Thanks!
