Re: [meteorite-list] Meteorite Found in India
<"The results of our study indicate that it is a rare iron meteorite having a significant radioactive content of 54 mn (manganese) and 57 co (cobalt)," said Mr Narendra Bhandari of the BSRI.> Too bad they don't say what "significant" is. The half life of 54Mn is 312.2 days and for 57Co it is 271.8 days. As a general rule after 7 half lives there is very little left. For 54Mn that is just under 6 years.So it is pretty obvious there is none left over from solar system formation. What there is most likely comes from cosmic ray exposure, which would be pretty much the same as for any other iron meteorite. There may be more radioactivity if there is more of the precursor material, but they don't mention any significant differences there. It may be significant scientifically, but in real world radioactivity safety procedures I doubt it is any different than any other iron in you collection. Unfortunately for the average person "significant radioactivity" brings visions of glowing rocks and lead gloves.Too bad they don't say what "significant" is. -- Eric Olson ELKK Meteorites http://www.star-bits.com __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] UCSD Discovery Suggests 'Protosun' Was Shining During Formation Of First Matter In Solar System
http://ucsdnews.ucsd.edu/newsrel/science/mcmeteorite.asp UCSD Discovery Suggests 'Protosun' Was Shining During Formation Of First Matter In Solar System By Kim McDonald University of California, San Diego August 11, 2005 >From chemical fingerprints preserved in primitive meteorites, scientists at UCSD have determined that the collapsing gas cloud that eventually became our sun was glowing brightly during the formation of the first material in solar system more than 4.5 billion years ago. Their discovery, detailed in a paper that appears in the August 12 issue of Science, provides the first conclusive evidence that this "protosun" played a major role in chemically shaping the solar system by emitting enough ultraviolet energy to catalyze the formation of organic compounds, water and other compounds necessary for the evolution of life on Earth. Scientists have long argued whether the chemical compounds created in the early solar system were produced with the help of the energy of the early sun or were formed by other means. "The basic question was, Was the sun on or was it off?" says Mark H. Thiemens, Dean of UCSD's Division of Physical Sciences and chemistry professor who headed the research team that conducted the study. "There is nothing in the geological record before 4.55 billion years ago that could answer this." Vinai Rai, a postdoctoral fellow working in Thiemens lab, came up with a solution, developing an extremely sensitive measurement that could answer the question. He searched for chemical fingerprints of the high-energy wind that emanated from the protosun and became trapped in the isotopes, or forms, of sulfide found in four primitive groups of meteorites, the oldest remnants of the early solar system. Astronomers believe this wind blew matter from the core of the rotating solar nebula into its pancake-like accretion disk, the region in which meteorites, asteroids and planets later formed. Applying a technique Thiemens developed five years ago to reveal details about the Earth's early atmosphere from variations in the oxygen and sulfur isotopes embedded in ancient rocks, the UCSD chemists were able to infer from sulfides in the meteorites the intensity of the solar wind and, hence, the intensity of the protosun. They conclude in their paper that the slight excess of one isotope of sulfur, ³³S, in the meteorites indicated the presence of "photochemical reactions in the early solar nebula," meaning that the protosun was shining strongly enough to drive chemical reactions. "This measurement tells us for the first time that the sun was on, that there was enough ultraviolet light to do photochemistry," says Thiemens. "Knowing that this was the case is a huge help in understanding the processes that formed compounds in the early solar system." Astronomers believe the solar nebula began to form about 5 billion years ago when a cloud of interstellar gas and dust was disturbed, possibly by the shock wave of a large exploding star, and collapsed under its own gravity. As the nebula's spinning pancake-like disk grew thinner and thinner, whirlpools of clumps began to form and grow larger, eventually forming the planets, moons and asteroids. The protosun, meanwhile, continued to contract under its own gravity and grew hotter, developing into a young star. That star, our sun, emanated a hot wind of electrically charged atoms that blew most of the gas and dust that remained from the nebula out of the solar system. Planets, moons and many asteroids have been heated and had their material reprocessed since the formation of the solar nebula. As a result, they have had little to offer scientists seeking clues about the development of the solar nebula into the solar system. However, some primitive meteorites contain material that has remained unchanged since the protosun spewed this material from the center of the solar nebula more than 4.5 billion years ago. Thiemens says the technique his team used to determine that the protosun was glowing brightly also can be applied to estimate when and where various compounds originated in the hot wind spewed out by the protosun. "That will be the next goal," he says. "We can look mineral by mineral and perhaps say here's what happened step by step." The UCSD team's study was financed by a grant from the National Aeronautics and Space Administration. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] Meteorite Found in India
http://www.navhindtimes.com/stories.php?part=news&Story_ID=08125 Meteorite found in Rajasthan The Navhind Times (India)" August 11, 2005 PTI Ahmedabad: Elaborate tests conducted on a meteorite fragment found after it had crashed in Rajasthan recently has revealed it to be a very rare iron meteorite exuding significant radioactivity. A variety of tests were conducted by scientists of the Phyical Research Laboratory and Basic Sciences Research Institute on the meteorite which fell at Bhuka village in Barmer district of Rajasthan on June 25, this year. "The results of our study indicate that it is a rare iron meteorite having a significant radioactive content of 54 mn (manganese) and 57 co (cobalt)," said Mr Narendra Bhandari of the BSRI. "It seems to have originated from the asteriodal belt between Mars and Jupiter and might have been 100 times bigger than the its present weight of about 2.5 kg," said the scientist adding that tests were still to be conducted to arrive at the estimated time the meteorite to travel from the belt to Earth. The meteorite, which fell in the farm of Mubeen Sindhi with a loud noise, made a crater of about half-a-metre and is actually an alloy of iron and nickel, said Mr Bhandari. "It is the first iron meteorite to fall in Rajasthan among the seven falls in the past 15 years," he said explaining the rareness of the cosmic object. The iron meteorite is the rarest of the three kinds of meteors, the other two being stony meteors and stony iron meteors, he said. "Moreover, for the radioactive isotopes of cobalt and manganese to be found together in a single meteorite is very rare and it is perhaps the first time they have been found on earth," Mr Bhandari added. We were able to detect the radioactivity because the meteorite was sent to us immediately after it fell, he said adding that radioactivity slowly wanes with the passage of time. "About 80 per cent of most meteors entering the Earth's atmosphere burn out. What makes iron meteorite rare on Earth is because unlike stony meteors they have a tendency to completely burn out," said Mr Bhandari who is also the president of International Lunar Exploration Working Group. The meteorite has a thick black crust with a golden or brownish tinge. The crust also has well developed regmaglypts (thumb marks formed when the meteorite enters Earth's atmosphere) typical of meteorites. "The tests conducted on a piece of the meteorite sent to PRL (a large chunk was also sent to the Geological Survey of India), also found it to be made of pure iron which is very different from the kind of iron usually found on Earth which normally exists as an oxide," he said. The iron and nickel alloy which the meteorite is made of, was formed at very high temperatures, in "reducing atmosphere" devoid of oxygen or water at least four-and-a-half billion years ago. The meteorite also has a special crystalline structure which is indicative of the slow cooling process it witnessed, Mr bhandari said. Talking about the meteorite's fall in June this year, he said, "This is the seventh observed fall in the past 15 years in Rajasthan the other six meteorite falls being at Didwana (1991), Lohawat (1994), Devri Khera (1994), Piplia Kalan (1996), Itawa Bhopji (2000) and Bhawad (2002)." Since only about 126 falls have been observed all over India in the past two centuries, this frequency of falls (one every two years) in such a small area of Rajasthan is very unusual. In comparison, no more than 10 falls have been reported from the rest of India in the past 15 years, he observed. Certain questions as to whether this observation is just a regional or temporal statistical fluctuation or whether the Earth is going through an unusually dense swarm of interplanetary bodies continues to remain unanswered, Mr Bhandari added. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Dolores Beasley Headquarters, Washington August 11, 2005 (Phone: 202/358-1753) George H. Diller Kennedy Space, Fla. (Phone: 321/867-2468) MEDIA ADVISORY: M05-136 NASA'S MARS ORBITER LAUNCH DELAYED 24 HOURS he launch of NASA's Mars Reconnaissance Orbiter (MRO) has been postponed. The new launch window is 7:43 to 9:43 a.m. EDT, Friday, August 12. The delay was called after engineers saw an anomalous reading in the hydrogen propellant loading system on the Atlas V. There was insufficient time in the launch window to fully investigate the reading. The Atlas V vehicle is being de-tanked. The rocket will remain on the launch pad, and the MRO spacecraft is secured. Tomorrow's weather forecast calls for a chance for isolated coastal showers. There is a 20 percent probability of not meeting the launch weather criteria. On launch day, August 12, the KSC News Center will open at 4:30 a.m. EDT. Foreign national news media should meet at Gate 1 at Cape Canaveral Air Force Station at 5 a.m. to be escorted to the KSC Press Site. NASA TV live coverage of the launch begins at 5:15 a.m. EDT.

[meteorite-list] Perseids Tonight
Dear Listees: A reminder for skywatchers and night owls that the annual Perseids meteor shower is expected to peak late tonight/early tomorrow morning. From UtahSkies.org: Time for the annual Perseid Meteor Shower. The event has been going on for a couple of weeks already as skywatchers have seen a dramatic rise in meteor counts. Well, you ain't seen nothing yet. The Perseid's peak very early on Friday morning (8/12). Highest counts are expected between midnight and first light (5am). If you're under dark, clear skies, you could expect to see upwards of 100 meteors per hour for a while. More info: http://www.utahskies.org/solarsystem/meteors/perseids/index.html We've been experiencing heavy rain and storms for several days in Tucson. Hoping for clear skies tonight.

Re: [meteorite-list] goran Lindfors lunar stuff
I get photos of what looks like some sort of sandstone from that guy regularly also. Usually a meg or more of photos at a time - which since I use yahoo and hotmail for email was a royal pain before they gave everybody hundreds of megs of space last year. It is so obvious even from a photo that these are not meteorites that I suspect that this guy is running some sort of criminal activity like money laundering or something. (Just a guess as I have no idea what he is up to but realistically anybody trying to sell something as a meteorite wouldent use something so obviously not a meteorite as what he is using. Therfore I can only assume that he is running some sort of non meteoritic scam directed at non meteorite people using fake meteorites). I once sent him a very polite email saying "Congratulations on finding a lunar but you sent me the wrong photos as the photos you sent were obvioously not of meteorites". I get a nasty email back saying that I am not a serious meteorite buyer and dont know what I am talking about. There is really nothing you can do with this guy other than block his email address. He is not a member of the IMCA or have any respectibility anywhere in the meteorite world so unless you are willing to take him to court your only option is ignore him. --- Michael Farmer <[EMAIL PROTECTED]> wrote: > This guy is an idiot, he sends nasty emails if you > request documentation on > his crap.
