[meteorite-list] Happy Birthday Siena
Hello all today is the birthday of the Siena fall, 16 June 1794, one of the 2 important and historical italian falls - after Albareto - where for first Ambrogio Soldani have put the question if the this rocks come from the space - sorry for Chladni but the first idea is come from Soldani 8 years first. Siena is one of the first meteorite falls to come in the British Museum. If interested in the story of this fall I have write a article for meteorite!

Re: [meteorite-list] Ot ebay reporting?
Just a side note to legal animal parts. One of the parks, might be in Nambia but it just excapes me right now, has had a program to eliminate the killing of elephants and rhinos by tranqing them and cutting off horns and tusks, there by, keeping the animal from being killed by poachers. This also serves as a source of income for the park. Mark - Original Message - From: Sterling K.

Hi, You will note that nowhere in her listing does the seller claim that she is selling elephant ivory, only ivory. Ivory, of course, is any mammalian tooth that's big enough to bother with. Since these pieces are 34mm in diameter, it could be any critter with teeth that big. The sale of elephant ivory is legal in the US if the ivory was imported before the ban commenced on 01-01-1973. I recently purchased a piece of legal elephant ivory on eBay, a slab 1/8 x 5/8 x 4-1/2, for $16.50. It came with papers like a pedigree dog, xerox of the import permit (with date), affidavits from transferring sellers, the cutter, etc., all ready for me to wave in the face of the Feds when they bust down the door with their no-knock warrant, searching for pachyderm teeth. Walrus and especially mammoth ivories, which is by definition fossil ivory, are much more expensive for some reason ($40 and $100, respectively, for a piece the size mentioned above). Whale ivory would be more expensive if you could find it. My guess is that the eBay seller is pitching water buffalo ivory, which is cheap, plentiful, not endagered as a species, and easily obtainable in Australia. So, what did I buy real ivory for? Not for a decorative purpose nor an embellishment. I cut a bridge saddle for a super rare high quality guitar. (The bridge saddle is that little strip of material the six strings rest over before they are pinned down to the bridge; it and it alone transfers the string sound to the face of the guitar, and nothing does that job like ivory.) I even managed to use only half of the piece of ivory, so I have enough left over for another bridge saddle, if I ever find another guitar good enough to deserve it. Sterling K. Webb -- -- David Freeman wrote: Dear List; Yup, antique, and/or pre early 70's is pre embargo (think it was 73). I have some. I seem to remember in the news in the past month or two that certain African nations are again able to sell (through government outlets) new ivory. The logic (through the UN...the most logical entity I know...Not), decided if the elephants were already poached and the ivory (numbering in the thousands of tons) was already harvested and the crooks paid with their lives that it was ok for the starving country to sell the ivory to help them out, instead of burning the large warehoused collections. I want to think that some of the moneys generated were earmarked to go back in to protection and game preserve work. Now if you want ivory, get some of the Mammoth ivory, or Walrus or other old ivories that can be had rather reasonably. So, depends when it was harvested and where . Dave F.

I believe that there is a cut-off date of when the ivory items were produced.

[meteorite-list] corkscrewing meteorites
Be carefull here. The dusttrails and/or persistent trains left by meteorites will start to twist after formation due to high altitude winds, often creating a cork-screw pattern in the dust-trail or persistent train. I've seen it happen many times with persistent trains of fireballs. It sometimes happens in seconds. This is not due to the meteorite itself cork-screwing down, but it might lure an eye-witness in thinking it was. This is not to say that I want to discount the possibility some do, but it is a fact, I have never seen any good photograph of a bright meteor corkscrewing, other than a few where the effect was instrumental (introduced by camera-movements), or likely to be so. - Marco -- Drs Marco Langbroek [EMAIL PROTECTED] [EMAIL PROTECTED] http://home.wanadoo.nl/marco.langbroek What seest thou else In the dark backward and abysm of time?

[meteorite-list] Screwball
Dear List; If one imagines any number of objects that go air borne at flight speed; either motorbikes, NASCARS, fighter jets, skydivers...the potential for a deviation from a straight path of flight is the norm rather than the exception. In baseball, we have a number of pitches that generate pitch (ha, ha), roll, and yaw on the ball. The screwball resulting from a ruffed up part of the leather covering on the ball has been banned for years. The ball sinks, drops, goes screwy with the change from aerodynamic equality. I think that anything other than a perfect sphere entering the atmosphere has the potential for a spin, turn, or drag/drift to one side or another. At that point it is a matter of velocity times rotational effect (and mass/inertia) as to whether we get cork screw. With the atmospheric break up of meteorites, we can see the drift and separation evident as the pieces drift down. If a piece came in a little fast at break up, and had a jagged or protruding area out of aerodynamic balance, the potential for a corkscrewer would be there. Next thread ,how perfectly round can ablation be. A pinch screwy himself, Dave F. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] M-V-5 Rocket Successfully Launches Hayabusa (MUSES-C)
http://www.isas.ac.jp/e/new/release/2003/05_06.html M-V-5 Successfully Launches Hayabusa ISAS May 15, 2003 The M-V-5 rocket carrying MUSES-C (Mu Space Engineering Spacecraft-3) lifted off successfully from Kagoshima Space Center (KSC) at 13:29:15 on May 9, 2003. The lift off was smooth and 350sec after launch the rocket released the 4th stage, which spun into the specified direction. NASA's Goldstone station received radio signals from MUSES-C 23 minutes later. From data transmitted through Deep Space Network (DSN), we confirmed that: sequences following 4th-stage separation were executed as planned; the explorer was put into the specified interplanetary orbit; and MUSES-C functions were normal. The MUSES-C spacecraft was renamed Hayabusa (Falcon). The launch was three years and three months after the failed launch of February 10, 2000. Corrective actions included changing the nozzle-throat material of each stage from graphite to 3D-CC (3 dimensional carbon-carbon composite) and static firing tests to verify the changes. We faced a number of unforeseen problems over the period but managed at last to succeed. The success is due to the strong will and dedicated efforts of all the people concerned in for return to flight of the M-V rocket. It should also be noted that we learned many lessons over the period. For example, our quantitative understanding on phenomena related to solid rockets has progressed remarkably. Technology for large-scale 3D-CC material construction and nondestructive testing has also advanced dramatically. Rocket operation for the flight started on April 21, while work for the explorer began in mid-March. All the team members held a meeting on April 27. The daily tasks took more time than expected and the team members worked usually until 8 or 9 p.m. On one particular day, work continued until 2 a.m. and the experiment team staff were extremely exhausted. In addition, I had to order the team to perform many arduous tasks, such as: a round trip to Tokyo to replace a defective part; operation checks from midnight to dawn; and nightlong work to test radio signals during cloudless condition. I would like to ask the team's forgiveness for these tough demands in consideration of the M-V-5's successful launch as scheduled. The launch was the final one before the integration of three space agencies. I believe that all M-V rocket launches hereafter will be successful by efforts of the team, even though the launch-operation scheme will change within the new organization. Finally, I would like to take this opportunity to express my sincere thanks to those who supported the launch. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] moon meteorites exhibit
Hi List, Another highlight of the next Ensisheim show (along with the magnetic determinations of meteorite types by Pierre Rochette, described in my last post) worth mentioning is by no means the recent acceptance of Norbert Classen and Siegfried Haberer from Germany, to exhibit most of their recent extraordinary lunar meteorite finds in Oman. Norbert and Siegfried found during their expedition last February some outstanding lunars with very exciting properties that will certainly provide revolutionary ideas and debates in the scientific community. I am not supposed to say more but the main masses and their cuts you will see on display for the first time, along with the corresponding didactic explanations, are certainly more than worth a visit in the exhibition room of the museum (where the original 53.831 kg of Ensisheim remaining mass are sitting). Their exhibit of lunars and matrians will implement the already scheduled display of the similar extraordinary meteorites originating from moon and mars found in Sahare and stemming from the exceptional collection of Bruno Fectay and Carine Bidaut. All in all, this amazing exhibit, enlightened by the pertinent lectures given by moon and mars meteorites specialists, Prof Gillet (Lyon) and Jambon (Paris) and complimented by a general overview of the continuation of our moon and mars knowledge since Appolo missions (by prof. J.C. Lefebvre) is a unique opportunity for everyone to learn more about our satellite and the red planet and on how some of their fragments eventually reached the earth surface.

If they can do that, then corkscrewing caused by a flat surface spiraling in the same phase is not out of the question.

[meteorite-list] NWA 869...type(s): towards a solution ?
Hello list, Regarding NWA 869/787 and their other paired friends, Dean Bessey recently wrote that: every institution that classifies NWA869 seems to get a different classification. This is actually true and probably debated in earlier posts. If I am correct with my files, (but it is so easy to be fooled), NWA 869 seems to have been typed first as L4 (A. Rubin) then L5 (Met. Bull.). NWA 787 (Farmer, Hupé...) was L6... Matteo's NWA 900 (also described and pictured in Norton's Encyclopedia) and supposed paired with the above, was suggested to be a L3.9-6 (Matteo) while Norton writes about the same: distinct chondrules and Fe-Ni clusters... suggest L4 (?) but there are also achondritic type materials in some clasts. I have a similar material in my collection and although it probably exhibits quite the same (complex) lithology as the above, it was claimed by the supplier to be first NWA 965, then recently corrected to NWA 905I did not find anywhere the description of this NWA 905.. Thus a lot of confusion concerning both the name and the type of this exceptional meteorite! Not mentioning the total weight known or recovered that stimulated recently a debate among the list. To add to the confusion, Anne Black wrote this morning that the meteorite AC 001 she is offering on E-bay (found by Alain Carion in Morocco in 2000 and under study) has a quite unusual type LL3/5. This is probably not the same meteorite as the above cited series except that my own AC 001 purchased last year in Ensisheim at AC's table, has a lithology that strangely resembles that of my NWA 905, which should also be our famous NWA 869 So far I am aware that this short statement throws even more confusion about what is what and which type is which... However, the purpose of this post is to tell you that by the end of this week, during the newt Ensisheim show, we might have a good opportunity to progress a little regarding the type of all these meteorites. Pierre Rochette, a well known list member and pertinent contributor, who recently published a new, rapid and efficient method allowing one to determine the type of any meteorite (at least stony), kindly proposed to help us determining the type of our unknowns (or doubtfull knowns). He will dispose of a special table during the next week held Ensisheim show, for doing this fairly intriguing determination, thus by Friday June 20 only, during the professional day. Whoever would be able to bring along, among other unknowns, some NWA 869 or alike for a megnetic determination, this would perhaps throw some light on our enigma. At least, I'll bring along for that purpose my NWA 905 (3 different slices with different lithoilogies each) and my two AC001 pieces. Pierre and I can make a short report on the results for the list after the show. For those who are not familiar with this new method, here is the reference: P. Rochette et al. (thus 7 other authors from France, Vatican, Italy, Spain Finland), MAPS 38(2), 251-268 (2003): Magnetic classification of stony meteorites: 1 Ordinary chondrites The paper provides database of megnetic susceptibility measurements on 971 ordinary chondrites. This property can be sucessfully used to characterize and classify OC type meteorites through a rapid and non destructuive measurement essentially determining the amount of metal in each sample which occurs in a very narrow range for each chondrite class. In this compilation, Pierre et al. confirmed the majority of known types but also proposed a new class for several meteoites, as different as (to take a few sometimes represented in collections): Kabo (was H4, now proposed L6) Wiluna (was H5, now proposed L or weathering) Albareto (was L4, now proposed L/LL4) Suizhou (was L6, now proposed L/LL or weathering ) Ceniceros (was H3.7, now proposed L3.7) Segowlie (was L6, now proposed LL6) Futtehpur (was L6, now proposed H5) etc. Glad if anyone has comments about the method or about the NWA 869 or alike puzzle.

That it is clear that this thus is a picture that was not taken from a steady tripod, but with a handheld moving camera with the shutter opened while the camera was moved. Hence, the corkscrew appearance in the picture is at least partly, if not whole, an artifact of the camera movement while the exposure was made; 2.

Re: [meteorite-list] 'Meteor' drop-tests, have been done?
Pekka List, At 01:58 16.06.03 +0300, you wrote: Hello, Bjorn and the list, we had some speculations last winter in Finland to try some kind of dropping, but as far as I know, nobody here has tried...;- We tried to find information about this kind of test, but with no results. We consulted people from different universities in Europe, US and Canada, and there was not information available in this kind of tests in practise. There are some scientists that do shoot small, mm-size, metal balls ito ice surfaces and study the resulting craters. They then use scaling laws to draw conclusions about the really big craters on icy bodies. Burchell and Grey at the University of Canterbury, England are two of them. But they are actually more interested in the crater form, not the cracking pattern around it. A crater is hardly of interest in the case of just the hole into a relative thin ice surface. I think the _cracking patterns_ in such cases is the feature that will tell the tale only. I'm also interested in looking at practical results in the nature, with different values of thickness of ice, temperatures, angle, speed. Think this can be also quite simply calculated and simulated, but I´m not a mathematician... Seems to be a bit removed from what you might see on a frozen lake some winter day.. Especially taking into account how easy it would be to do a drop-experiment. If you know the thickness and the structure of the ice, mass / size / angle of the falling specimen, this should not be a problem for a professional. It also should be remembered, if you make this kind of test somewhere, it´s only valid in exactly same circumstances. Usually the meteoroids don´t have any cosmic velocity left, when they drop, so they come down in free fall. The quite simple test is try to shoot a hole in the ice. Let´s say, you use 9.00 mm bullet and check the exact angle and the distance from the ice, when shoot, so the energy of the hit can be exactly calculated. More problematic case is the structure of the ice. If we are talking about steel-ice in the middle of the winter, let´s say, 60 cm:s thick, I bet, the hole you can get, it´s not deeper than 15 cm:s. The case is different in spring-time, when the ice with same 60 cm:s thickness is usually layered at least in 2 parts, strong steel-ice on the bottom, and week ice containing lot of water on the top. But anyway, think some modelling can be made. This may be a bit safer way than drop the stones from the plane. Anyway, if you are going to make this test, please, let me know the results, and also the dropping-area, so I know to wear a safety-helmet if happen to be near...;- Well, I'm probably not trying in the summer-time, even though there are lakes in the mountains here that are covered in ice at this time. But they probably do not have the sought after type of ice. Anyway, I'm still surprised that no one seems to have done such tests previously...

Re: [meteorite-list] Pasamonte (corkscrewing meteorites)
Hi Steve and list Not being familiar with aerodynamics and such, I can't speak with authority, but can pose the question of that caused by the wash of the item traveling through an atmosphere. If anyone has ever seen a rocket launched (the smaller ones such as I worked with years ago, nike hercules), they often have a convoluted and twisted trail simply from the speed at which they travel through the atmosphere and the resulting remix of atmosphere behind them (because of the displacement of air). This effect is often seen in wind tunnel tests which is done on purpose using smoke to better see the tail wash and turbulences cause at higher velocities.

If they can do that, then corkscrewing caused by a flat surface spiraling in the same phase is not out of the question. Hi Steve and others, That is a good one. My first hunch would be, that fragmentation is a violent event and that what different fragments do is more related to the explosive fragmentation event including separation due to the formation of independant bow shock fronts for each fragment than to their shape. At least that is what I understand from reading in Hills Goda, The fragmentation of small asteroids in the atmosphere (Astr. J. 105, 1993). Yet, you can indeed wonder what shape would do, although with as much as 70-90% or more of the initial mass ablating, I think shapes for meteorites in flight are highly transient and it would appear flight is shaping them (hence the formation of oriented meteorites) rather than them shaping flight. That's my two cents worth of it, but I am no expert in aerodynamics of high velocity objects, nor the process of meteorite ablation and fragmentation.

Re: [meteorite-list] corkscrewing meteorites
Hello People, Just a thought here, but in my younger days I was pretty handy with a slingshot and my usual ammunition was mainly rocks. The rounder they were the straighter they flew. Usually they would slice left,right ,up or down but on occasion one would corkscrew. If I remember right it was the oblong ones that were most likely to do it. Maybe someone ought to do a test.

Re: [meteorite-list] corkscrewing meteorites
At first, as the meteoroid is entering the atmosphere at high altitude and hypersonic velocity, I imagine that there would not be much deflection in its flight no matter what the shape. But as it penetrates to greater deph and its speed is reduced, then aerodynamic forces must have a greater influence. If the object is spinning this could deflect is trajectory in some way. But if the object breaks as most meteoroids do, then it is possible that some of the fragments will have odd shapes, like flat slabs. What will these do in the atmosphere? I know that with regards to Pasamonte, there were reports of the fireball having a corkscrew appearance, and I think that there are other reported sightings of the same.

You can get a battery operated one, that never needs to be set and is never wrong by more than a second, for about 30 bucks. http://store.yahoo.com/radiowatches/seikrwavrada.html (This is not a commercial, just an example...)

[meteorite-list] Meteorites on Mars?
List: With all the Probes heading for Mars I have been pondering a bit on how meteorites on mars might differ from those on earth? How would an asteroid fragment react with the atmosphere of Mars with its different composition and density? Does the Martian atmosphere have enough density to stop an incoming fragment? Would the smaller mass and less gravitational attraction have any affect? Regards, Fred Olsen __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
