They have even put pieces of the meteorite in water with petals. My son, Vishwarasi picked up the stone and later I found that he has developed rashes on his hands. As, I saw the stone flowing in the water I felt that it belongs to Lord Ram or maybe some other god, said Hansa Bai, villager, Jamnagar. Officials in the area say occurrences like a meteorite shower are often seen as divine warning for some impending doom or misfortune. Meanwhile, a two-member team of the Geological Survey of India has arrived in Rajkot to examine the remains of the meteorite shower over Saurashtra and Kutch region of Gujarat on July 31. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Dawn Journal - July 29, 2006
http://dawn.jpl.nasa.gov/mission/journal_07_29_06.asp Dawn Journal Dr. Marc D. Rayman July 29, 2006 Dear Dawnthusiasts, Dawn continues to keep its human handlers very busy as preparations continue on schedule to meet the planned opening of the launch period on June 20, 2007. Much of June 2006 was devoted to conducting the comprehensive performance tests (CPTs) described in the previous log. In these tests, most of the hardware and software subsystems already on the spacecraft were exercised to help uncover problems ranging from incomplete solder connections on a microchip or a broken wire, to software bugs, to unexpected interactions between subsystems that must work together. Of course, each subsystem was tested extensively as it was being built, but some afflictions may remain hidden until the subsystem is operating on the spacecraft with other subsystems. As thorough as the CPTs are, testing will become more and more demanding over the coming months as the spacecraft is asked to perform in ways progressively more like what it will encounter during its voyage to the asteroid belt and its explorations of Ceres and Vesta, the most massive bodies in that region of the solar system. The upcoming tests will be described in future logs. The CPTs yield a tremendous volume of data, and engineers are still analyzing the details of their subsystems' performance, but all indications are that the tests went extremely well. As our humble human readers know, some errors are inevitable in a design as intricate and complex as one of Earth's interplanetary spacecraft. So far it appears that all such flaws are easily correctable. Some subsystems have not yet had their first CPT. The ion propulsion subsystem and the instruments for collecting scientific data are awaiting their tests in August. We will introduce each of Dawn's subsystems in the next log. Some of the ion propulsion subsystem's individual components received some extra testing recently before being mated to the spacecraft in June. The power processing units have to provide the properly controlled voltages and currents to different elements of the ion thrusters, which apply the electrical power to xenon gas to produce fantastically efficient propulsion, without which Dawn's ambitious mission would be quite impossible. Each unit will process up to 2500 watts (much more than the average house consumes), and we wanted special assurance that these devices would perform reliably on the mission. So in addition to the testing they received at the company that manufactured them for Dawn, each one was subjected to further trials in one of JPL's laboratories. The devices were operated for about 20 days in vacuum chambers. During most of that time, the units were pushed to the highest temperature they will experience on the spacecraft of 35°C (95°F). Both units passed with flying colors (what other kind of colors would you expect for space hardware?), adding to the confidence that they are up to the rigors of Dawn's mission. While operating in their thermal vacuum chambers, the power processing units were under the control of the same software that runs in the ion propulsion control unit on the spacecraft. So this work provided a bonus opportunity to test the software that operates this complex subsystem on its travels through deep space. Each of the three ion thrusters will be mounted on a mechanism that allows its pointing direction to be fine tuned by other software on the spacecraft. As we will see in the next log, this accurate aiming is essential, so if one of these mechanisms fails, the attached thruster would be useless. To verify the robustness of the design for the mechanism, a test unit was subjected to 10 times the amount of work the ones to be flown on Dawn will have to provide. The performance was flawless. After the ion propulsion subsystem testing and the first set of CPTs were completed in June, the focus of the Dawn team's activity in July was on what nontechnical readers might think of as baking the spacecraft. The technical term used by the engineering team was -- well, baking out the spacecraft. This was not a test; rather, bake-out was intended to heat the spacecraft to drive off contaminants it might have collected, despite the assembly having been conducted in a specially controlled clean room at Orbital Sciences Corporation. The first step in the bake-out was to clean the oven in which the baking would occur, a cylinder 3.7 meters high and 4.9 meters long. (Ever poetic, team members fondly refer to this facility as the 12 by 16 foot chamber.) For several days, the chamber was heated to 95°C (203°F). This ensured that its interior would be free of chemical residue that might contaminate Dawn. With the chamber certified to be clean, the spacecraft was moved in. As it is not completely assembled yet, some of the flight equipment was simply placed in the chamber with the spacecraft. After the chamber was sealed, it took 7 hours to
[meteorite-list] 145-Million-Year-Old Morokweng Impact Crater
http://www.vuvuzelaonline.com/index.php?option=com_contenttask=viewid=483Itemid=51 Our Boffins find 145-million-year-old meteor relic Written by MARIZANNE KOK Vuvuzela Online 03 August 2006 THREE Wits academics were part of an international team that found pieces of an ancient asteroid in the Morokweng crater, located beneath the sands of the Kalahari Desert. Dr Marco Andreoli, Prof Lew Ashwal and Prof Rodger Hart, all involved with the Wits School of Geosciences, were among the team of 11 who drilled loose an asteroid relic and subsequently published an article about the find in the Nature journal. A soccer-ball-sized meteorite fossil was discovered in the Morokweng crater when scientists drilled holes into the area where an asteroid with a diameter of 5-10km struck the Earth 145 million years ago. It is a groundbreaking discovery because scientists commonly accepted that objects melted or vaporised at the moment they crashed into the Earth's surface. The collision of an asteroid with the rocky surface of our planets generates enormous heat which has the potential to turn rocks into gas It is reported that a 10km-diameter object will produce temperatures of between 1 700 and 14 000°C. The Morokweng crater is now 70km wide, but according to Prof Ashwal it was probably much bigger after the initial impact. It possibly became smaller because of the effects of erosion over time. The discovery of a 25cm-long asteroid relic, the first ever to be found on Earth, will not only enable scientists to study a piece of space rock that hit the earth millions of years ago, but it can also help them to understand the different kinds of meteorites in existence. It blows the field of meteorite study wide open. We now need to rethink everything we ever thought we knew about meteorite craters, said Ashwal. According to Ashwal, the team went to the Morokweng crater to look for something. We're geologists, we go wherever we think there's a chance of finding something. We had no idea we would find something like this, he told Vuvuzela. Ashwal said that a colleague assembled a group who could drill in the Morokweng crater many years ago. The crater cannot be seen from the air because it is covered with sand. The only way it could be found was through geophysical photography, which takes a picture of an area's magnetic field. On such photographs it is easy to spot circles on the planet's surface, which can only be one of a few things. These include volcanoes or, as in the case of Morokweng, meteorite craters. Ashwal said he and the rest of the team had been very surprised by the public's reaction to the discovery. The professor himself has already appeared on television and has done numerous interviews with radio stations, magazines and newspapers. People's imaginations have really been captured by this. Of course Hollywood movies like Armageddon have played a part in the public's interest in these things, but we're not complaining. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Dear Menno, and All, You probably didn't intend to sent this to the list, but solely to Adam. Hmm, but since it showed up I guess I owe you a response. NWA 3186 actually is a new martian meteorite, but it's not really new. It belongs to the NWA 1068/1110 pairing grouplet from Maarir, Morocco, and it has a small TKW of just 15g, consisting of mostly small fragments. It has been classified by Dr. Ted Bunch (NAU), but it's not yet official because it hasn't been voted upon by the NomCom of the Meteoritical Society, thus far.

[meteorite-list] More about beautiful Lahoma
Hello Mark B., M.C., and List, My three Lahoma slices arrived today and what shall I say, ... they are out of this world! Beautiful shades of green, delicate shock veinlets, abundant troilite (!), very rich in FeNi or to use Michael Cottingham's own words ... loads of metal. The oval metal-sulfide inclusion that I mentioned in my previous post measures a whopping six millimeters. What is also very extraordinary about this inclusion is that the troilite is surrounded by FeNi metal and not vice versa. My 23.39-gram slice features a 3.5 millimeter FeNi bleb so close to the outer edge of the cut and polished slice that most of it (ca. 90%) is embedded in the pitted crust. This same slice has one of those dark inclusions but not only is it dark but also featureless and devoid of FeNi metal. There is a thin seam of minute FeNi dots all around it but the interior of this dark inclusion is virtually free of nickel-iron. So maybe I am looking at a melt inclusion (shock-melted as Lahoma is shock stage S4). Whether these dark inclusions are xenolithic I don't know (yet). Time and professional meteoriticists will tell :-) When I mentioned the abundance of troilite, I added an exclamation mark because there are not very many L5 chondrites with such an abundance of troilite - only the fresher ones like Mount Tazerzait, Baszkowka.

[meteorite-list] Is that a bulge at your equator, or...
http://www.cosmosmagazine.com/node/515 Solved! Mysterious Moon bump explained by eccentric orbit by Marie Theresa Bray Cosmos Online SYDNEY, 4 August 2006 - The far side of the Moon boasts an unusual bulge at the equator, whose origin has baffled scientists for centuries, but according to a new study in today's issue of the U.S. journal Science, a possible explanation could be that early in the Moon's history the orbit may have differed during the crucial stage in which the lunar magma ocean was solidifying. This age-old mystery of the 'fossil bulge' was first brought to attention by mathematician Pierre-Simon Laplace in 1799, and since then various explanations have been proposed but have failed to fit the exact dimensions of the Moon. Today's study showed that the moon's shape can be justified if the Moon was in an oval, or 'eccentric' orbit, 100 million years after its formation. Ian Garrick-Bethell, co-author of the paper and PhD student from the Massachusetts Institute of Technology, USA described the resulting shape of the moon as like half an American football. For the model to work, Garrick-Bethell had to take into consideration the process of how the fossil 'freeze-in', or solidification, actually works. He framed his research around the question: how can you freeze-in a single-axis football component in a plastic Moon, when the Moon is continually spinning with respect to the Earth thereby changing the axis that gets the football deformation? Along with fellow colleagues, Garrick-Bethell modelled specific orbits that were possible solutions, including one similar to the present state of Mercury. The researchers said that if the Moon was spinning 1.5 times on its own axis for each time it orbited the Earth, instead of only once as it does now, it would have been spinning fast enough to stretch the cooling magma. At any point in its orbit, the Moon's rotation stretches it like a flattened basketball, while tides from the Earth stretch it like a football, said Garrick-Bethell. We thought of different scenarios that could increase the flattening component, and one of the most straightforward ones is to simply assume that the Moon was once spinning faster. It is well known that [an eccentric] orbit is stable for Mercury (which has a 3:2 resonance), so we explored what values of eccentricity would give the current lunar moments of inertia in a 3:2 resonance, if any, explained Garrick-Bethell. According to Garrick-Bethell, these findings can be used for future work along similar lines as there is still much left to be studied about the evolution of the Earth and Moon system. There are always new ways of looking at old problems. Very little is definitively known about the early evolution of the Earth-Moon system, he said. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Is that a bulge at your equator, or...
The far side of the Moon boasts an unusual bulge at the equator, this age-old mystery of the 'fossil bulge' was first brought to attention by mathematician Pierre-Simon Laplace in 1799, How could they ascertain this phenomenon on the far side of the moon in 1799? WOW ain't Mathematics magnificent!!

[meteorite-list] Introduction...
Dear Adam, and All, I guess I owe you an apology for sending my private mail to the entire list, sorry about that... Perhaps a good occasion for presenting myself to the list though, as I am following the postings for the last 4-5 years without really introducing myself. Although I am working in an entirely different field as a psychologist and a university lecturer, I have always been fascinated by everything from outer-space. I am from the lunar-landing Apollo generation and since I found out about meteorites being sold at Ebay I have spent most of my spare time (and money ;-) ) on building up a collection through the last five years or so. I have specialized on collecting smaller stones and am currently "focused" on martians, which is why I sent my mail to Adam. I'd like to take the opportunity to thank so many of you dealers, especially Adam Hupé, Mike Farmer for making the collecting of meteorites possible. In addition Imuch appreciate the enormous amount of interesting info I have been able to obtain from so many of you from the list. It really is a pleasure to be part of it all. Again apologizing to Adam, and sending you all my very best regards fromthe Netherlands!
