Yousef Is the same problem of the famous Boggy Creek lunar fake, I have received this email from Mr.BCC: OK if I send you a sample of lunar piece. I will send a slice because I cannot send a vial of crushed material. The sample will be a very nice size and I can send picture of it. Can I send it to some place in America instead of Italy. I cannot afford the postage all the way to Europe. In exchange for the sample you have to promise that you will remove me from your meteorwrong list because these samples are not meteorwrongs. You already saw the chemical analysis reports on my web page. And I have more reports I have not even posted. Are you going to remove me and apologize. I want an apology too because you were wrong. S. Ray DeRusse http://www.bccmeteorites.com Well, I have ask a piece with photos from where is cut from the main mass - to much easy take a piece of a real lunar meteorite and pass for a piece of Boggy Creek - the piece, I have write when I receivec the piece I send to my Institute in Paris or Germany for the analysis and when I have the confirm is a real lunar meteorite I send a copy of the analysis to Mr.BCC. I never received a answer from Mr.BCC. Is only a false person. Yousef why you no send a piece of your lunar meteorites to Mr.BCC, he give to you a 100% confirm is all lunars meteorites, but unfortunately not the Meteoritical Society C.

[meteorite-list] North American Impact Craters
Paul Heinrich inquired: What was the most recently discovered impact crater for the United States? Hello Paul and List, E.M. Shoemaker et al. (1995) Impact crater identified on the Navaho Nation near Chinle, Arizona (abs. Meteoritics 30, 1995, p. 578): A small impact crater has been identified about 8 km north of Chinle, Arizona, on the Navajo Nation. Preliminary studies show that the crater is in a north-south dircection, measuring about 23 x 34 m in diameter, with a depth of about 1.3 m. The impact origin of the crater is identified by its shape, subsurface deform- ation, and an Fe-Ni oxide fragment. We estimate the age to be about 150-250 yr. It doesn't matter whether the structure is buried or deeply eroded. Maybe this one: C. Koeberl, W.U. Reimold, R.A. Powell, Shocked Quartz and Impact Melt Rock at the Ames Structure, Oklahoma (abs. in Meteoritics 29, 1994, 483): The Ames structure in NW Oklahoma (centered at about 36°15'N, 98°12'W) is evident in the form of a relatively circular, concentric, structural depression with a minimum diameter of about 15 km, on top of the Upper Ordovician Sylvan Shale. The feature is covered by about 3000 m of sediments. It is marked by two concentric rims, an outer ring ... that is ca. 1.5-3 km wide and an inner ring structure that seems to be the collapsed remnant of a structural uplift ...

[meteorite-list] Meteor Trackers Called in to Predict Trajectory of Columbia Debris
http://space.com/missionlaunches/sts107_meteor_030218.html Meteor Trackers Called in to Predict Trajectory of Columbia Debris By Jim Banke space.com 18 February 2003 HOUSTON -- Columbia investigators are looking for help from experts who track meteors entering Earth's atmosphere so they can better predict where in the California mountains a potentially telling piece of debris from the doomed shuttle might have landed. NASA officials are interested in finding the material because it could help pinpoint what part of Columbia's heat shield failed first and allowed superhot plasma to flow into the spacecraft. It is believed this eventually led to the break up of the vehicle and loss of seven astronauts. So far there has been no luck locating any confirmed pieces of debris west of Texas despite hundreds of reports, NASA officials said Tuesday. But in the Sierra Nevada mountains of California there is strong hope that one or two larger pieces of debris, perhaps a reinforced carbon-carbon (RCC) panel from the leading edge of Columbia's left wing, might be sitting among the trees. Several eyewitnesses in the area saw Columbia fly overhead on Feb. 1 and saw one or two large pieces fall in flames away from the vehicle, followed by several relatively tiny pieces of debris. A few moments later, residents throughout the mountain range heard sonic booms and strong rumbling noises much like thunder, said Doug Kohl, a former shuttle engineer who now lives among the Sierra Nevada mountains. As the local space shuttle expert, Kohl has been in constant contact with the NASA debris team in an effort to pin down where the material might have landed. As part of that effort, Kohl said NASA was seeking the advice of meteor experts. While Columbia was still too high to be heard as it flew overhead, pieces falling from the vehicle could have made those sounds, which would be similar to the sound a small meteor makes as it entered the atmosphere. By combining all the visual sightings and audio descriptions, which varied depending on what side of what mountain a person was on, it is hoped that meteor tracking experts will be able to plot the debris' impact point. NASA is in the process of funding a meteor expert to give an estimate of the trajectory of the falling debris and determine if the height and velocity of Columbia was sufficient to have cleared the Sierra Range, Kohl said. NASA spokesman John Ira Petty at the Johnson Space Center could not confirm whether NASA or the Columbia Accident Investigation Board (CAIB) was seeking the help of any meteor experts in California. The independent board, led by retired Navy Admiral Harold Gehman, is overseeing the inquiry into the Columbia incident. On Saturday, former Air Force Secretary Sheila E. Widnall joined the CAIB, becoming the first woman on the panel. Gehman Jr., confirmed Widnall's appointment as board members left NASA's Marshall Space Flight Center for Louisiana to tour the Lockheed Martin factory that makes the shuttle's external fuel tanks. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Meteor Trackers Called in to Predict Trajectory of Columbia Debris
It's unfortunate that some of the obvious tools that could be used to increase the efficiency of the search are lacking. NASA's existing data on the position has been released in poor map formats. There should be an effort undertaken to coordinate the effortvia a common topo software platform, updated with GPS locations of verified debris finds, and NASA provided wind vectors over the field. That's the most efficient method of determining likely trajectories of debris.

[meteorite-list] Not really...
Re: Meteor Trackers Called in to Predict Trajectory of Columbia Debris Actually, NASA did not confirm this... NASA spokesman John Ira Petty at the Johnson Space Center could not confirm whether NASA or the Columbia Accident Investigation Board (CAIB) was seeking the help of any meteor experts in California. The premise of this Space.Com article rests entirely on the word of a former shuttle engineer from California. I doubt that he would even qualify as a NASA official, whatever that elusive term means. And, before my nasa.gov email address gets me in trouble by being declared as a NASA source, let me make clear that - neither I, nor any meteor expert that I know of, have been approached by NASA for help. What I can confirm is that a predicted trajectory and probable debris field has already been plotted!! It was calculated by our own List member, Rob Matson, on his own time, at his own expense, without any funding from NASA. His data is published at this URL: http://groups.yahoo.com/group/debris-locators/files/ Before I went to Tucson earlier this month, I set up a discussion group on YahooGroups so that members of our meteorite-recovery team could have a place (other than existing meteorite-lists) to discuss the O.T. subject of the STS-107 disaster and how best to help NASA locate debris. Before I returned from that Tucson trip, Rob Matson had already calculated and uploaded a map of a ground-track for the Columbia STS-107 re-entry flight path. Once again, this was accomplished before NASA published their web site. Now the Debris-locators Group will continue its theme of lead by example, by supplying links to official NASA web sites for people who wish to report debris locations, at the following URL: http://groups.yahoo.com/group/debris-locators/links Access to these links can be made by obtaining a Yahoo ID name and password at this web site: http://groups.yahoo.com/group/debris-locators With best regards, BOb Verish Moderator, Debris-locators P.S. - the Johnson Space Center Debris Hotline-number is (281) 483-3388 - Original Message -- [meteorite-list] Meteor Trackers Called in to Predict Trajectory of Columbia Debris Ron Baalke [EMAIL PROTECTED] Tue, 18 Feb 2003 12:37:18 -0800 (PST) http://space.com/missionlaunches/sts107_meteor_030218.html Meteor Trackers Called in to Predict Trajectory of Columbia Debris By Jim Banke space.com 18 February 2003 HOUSTON -- Columbia investigators are looking for help from experts who track meteors entering Earth's atmosphere so they can better predict where in the California mountains a potentially telling piece of debris from the doomed shuttle might have landed.

[meteorite-list] follow-up finds and their documentation
Hello all, I'm about to ask one of those wandering (also wondering) questions again...one that probably won't be answered to everyone's satisfaction, especially mine. Here goes... With all the latest Campos, Sikhote Alins, Kainez, Gao, Gold Basin, and others (I'm sure) being found these days...what (if any) verification and documentation is done with theselatest finds of known meteorites. Are finders required/supposedto follow any particular stepsto comply with the rules(whatever they are)of the Society that should eventually affect the total weights for these known falls/finds. Is the documentationof these and other "follow-up" findsout of control these days with the interest of meteorites being so high, and the desire to find more specimens paralleling that interest?I'm just curious. It doesn't bother me one way or the other...I just find the issue very daunting from a documentation point of view. I suppose a newly foundSikhote Alin looks like the ones found years before...and that most buyers look at it and say that is a SA andwould buy it. Is it documentedand added it to a running total? Is it supposed to be?Campos are also somewhat distinct in their appearance, but I'm not sure I could tell if one is for sure...if someone asked. The stones are often distinct in their appearance for a given name meteorite, and most buyers know what they are looking at...but (for example)some Gold Basin look just like many NWA's found in recent years.Weathered...and old looking. The source of supplieris always the key for us buyers...we have to have trust. The IMCA helps this situation in my opinion.Another key is tovisually recognize the look of a particular meteorite from experience. A problem with this is that the experience level for recognizing a given meteorite can have a wide range within a group of buyers. Notice I did not lump NWA's into this because it becomes even more gray as you look at them...from my simple mind's perspective. However, the scrutiny is much higher for them than the others...even though the level of "documentation" maybe the same...none, other than it looks like the others and were found in the vicinty of the original finds.
