Re: [meteorite-list] What are the FeO/MnO Ratios for the Kalahari 008, 009?
Dear List, An update, it looks like even though the two Kalahari lunar meteorites have completely different classifications they are paired. This makes sense since they were found just 50 meters apart.

Re: [meteorite-list] What are the FeO/MnO Ratios for the Kalahari 008, 009?
When this meteorite came to my attention as a member of the NomCom, warning bells went off in my head too. Enough evidence was presented to us to convince us that these were meteorites, although I expected this not to be the case, that we had to name them. But the find story is very odd. My reading of it is this: somebody who knows nothing about meteorites is driving his vehicle in the Kalahari. In a brushy area (based on satellite imagery: get World Wind, then search the MetBull database for Kalahari 008/9 and click on the nasa link to see the place), he parks in front of a sand dune and there he sees a rock: no fusion crust, probably very nondescript looking, the size of a cantaloupe melon. Oh, he says, here's something cool... a rock! I think I'll drag this 30 lb thing back home with me. But first, I think I'll comb the area for more.

RE: [meteorite-list] Question on oriented SA shrapnel
Martin, Thanks for the link, very interesting, (though somewhat simplified imho). There have been quite a few oriented (with flow lines) SA shrapnel pieces pulled out of trees etc, it will be interesting to see if anyone has any idea's as to the formation mechanism. If the 3rd and 4th detonation/fragmentations where too low, (for there to be enough flight time for flowlines to form) and the explosion on impact (the normal shrapnel forming process) was not consistent with flowline formation, then the question is, how are they formed? I guess the flowlines on my SA shrapnel could conceivably be shock induced lines formed by the explosive energy during impact? But some of the examples ive seen pictures of, look exactly like normal flow lines.

Re: [meteorite-list] Question on oriented SA shrapnel
I've been around this so long ,it never occured to to think this was the result of ground impact, but I understand how it would look that way. When one thinks about it, All or the SAwe find was shrapnel-form at the beginning of breakup. Fragments which separated earlier had longer opportunity to round off and regmaglypt. So far as I understand the physics, shearing stress which exceeds the cohesiveness of the meteoroid body can begin high up(15miles?) where the density of the atmosphere presents enough resistance and reaches maximum around 5 miles above sea level. I think the artwork suggests a massive main body disruption high up , which would have yielded a swarm. Seems there were perhaps a few subsequent bursts down the smoke stream. We might want to look at the SA Postage Stamp again. When you see shrapnel which is ripped and torn and remember this is iron we are talking about, this only gives a glimpse of what terrific energy absorbing potential the atmosphere has.

RE: [meteorite-list] What are the FeO/MnO Ratios for the Kalahari 008, 009?
Hi Adam, Martin, Jeff, and All, First, as for Martin's question - it's not that unusual that two different sized individuals of one and the same fall land that close to each other. Take for example the 8 kilo + main mass of the SaU shergottite strewnfield (SaU 008). Other, much smaller stones (SaU 051, and other stones comprised under the original SaU 008 designation) were recovered from the vicinity of the main mass. I could quote other examples, such as the Dhofar 302/908 strewnfield, where very small individual masses (not fragments) and larger stones were found within the distance of less than 100 meters. This certainly depends on the original impact angle of the fall, and it doesn't sound that unusual to me. As for the CRE and terrestrial ages of Kalahari 008, and 009, you have to read Kuni Nishiizumi's study with utmost care. He isn't saying that the terrestrial age is several hundred of thousand years - he's just confronting us with two possible scenarios that might explain the cosmogenic nuclide values within these rocks. The first scenario proposes a long terrestrial residence time at the find site (that also would be valid for a terrestrial rock subjected to the same conditions!!!), and the second - more probable scenario - proposes a very short transition time, and the implantation of these radionuclides in space. So don't mistake the first scenario for a calculation of a terrestrial age for the Kalahari lunaites. As far as I know, short transition times, i.e. CRE ages, make it more or less impossible to determine a terrestrial age (at least via the usual C14 analysis). A terrestrial age hasn't been determined for Kalahari 008, and 009, and thus there might be no contradiction at all between the W1 classification, and the other given data. Last but not least, I agree with Jeff Grossmann's notion that the find story is odd. Unconfirmed rumors have it that these lunaites were either found in South Africa or in the neighboring Namibia (both countries with strict meteorite laws), and that the find location in Botswana was just made up for obvious reasons. However, these rumors aren't consistent with the fact that the finder obviously isn't interested in selling any of his stuff - it wouldn't make much sense to make up anything in this case... Anyway, the story is strange, and it sounds improbable that a person who's not into meteorites at all recovers a large lunaite, AND - having no idea of what he has there - combs the place for additional fragments. That's really odd. Lunatically yours, Norbert -Ursprüngliche Nachricht- Hi Adam, I don't know strewnfield stats so well, but for the case, that they aren't fragments of the same stone, which were transported later by a mechanism, the heck I dunno which, wouldn't it be highly improbable, that two stones of a fall landed so close to each other, especially as they have such different sizes? ???

-- Forward Message -- http://www.universetoday.com/am/publish/10th_planet_controversy.html 10th Planet Controversy Universe Today August 9, 2005 Summary - (Aug 9, 2005) Jose Luis Ortiz had no idea that his announcement on July 29th of the discovery of a big Trans-Neptunian Object (TNO) would kickstart one of the most confusing and controversial days for the astronomical community in recent years. The astronomer from Sierra Nevada Observatory, Spain, sent an e-mail detailing his findings with the subject Big TNO discovery, urgent to a mailing list for astronomers. A few hours later, reports surfaced on some astronomical websites indicating that the object found by Ortiz, designated as 2003 EL61, was twice as big as Pluto, but they were quickly dismissed by Ortiz. Full Story - At the same time, another team led by astronomer Mike Brown of Caltech reported they had been observing 2003 EL61 for almost a year, but were waiting to analyze data from the Spitzer Space Telescope before announcing the discovery. There is no question that the Spanish group is rightly credited with discovery, Brown stated on his personal website. Even if they had found the object only this year and announced its existence, they would still be considered the rightful discovers. We took a chance that no one else would find it while we were awaiting our observations from the Spitzer Space Telescope. We were wrong! And we congratulate our colleagues on a very nice discovery. But just hours after that, Brown announced to the media the discovery of two other big TNOs, designated as 2003 UB313 and 2005 FY9. Regarding the first one, he stated that it's about three times as far from the Sun as Pluto, and it's definitely bigger than the ninth planet. Brown's team discovered 2003 UB313 on January 8th, but wanted to further analyze their observations. However, they were forced to announce their results on Friday evening because word had leaked out he said. In mid-July, short abstracts of scientific talks to be given at a meeting in September became available on the web. We intended to talk about the object now known as 2003 EL61, which we had discovered around Christmas of 2004, and the abstracts were designed to whet the appetite of the scientists who were attending the meeting. In these abstracts we call the object a name that our software automatically assigned, K40506A -the first Kuiper belt object we discovered in data from 2004/05/06, May 6th-. Using this name was a very very bad idea on our part. Unbeknownst to us, some of the telescopes that we had been using to study this object keep open logs of who has been observing, where they have been observing, and what they have been observing. A two-second Google search of K40506A immediately reveals these observing logs. According to Brown, from the moment the abstracts became public, anyone with an Internet connection and a little curiosity about the K40506A object could have found out where it was. Brown was quick to point that he believes the fact that this discovery happened days after the data were potentially available on the Web is a coincidence. But some people in the community privately expressed their concerns to me that this coincidence was too good to be true and wanted to know if there was any possible way that anyone could have found out the location of our object, he added. At this point, Brown contacted Brian Marsden at the International Astronomical Union's Minor Planet Center (MPC). Brown told him confidentially about the two objects not yet announced (2003 UB313 and 2005 FY9), expressed his concerns that someone might be able to find their data and attempt to claim credit for discovering these objects, and sought advice. Marden found that someone had already used the website of the MPC to access past observations of one of the objects and predict its location for that night. The past observations were precisely the logs from the telescope that Brown's group had been using. We had no choice but to hastily pull together a press conference which was held at 4pm on the last Friday in July, perhaps the single best time to announce news that you want no one to hear, said Brown. However, some astronomers have a very different opinion about Brown's announcement. The group of Dr. Brown decided, as in previous cases, not to make public its detection until they finished their observations and their research work, and until the object was in conjunction with the Sun so that other people couldn't observe it, stated Dr. Javier Licandro in an e-mail sent to a Spanish-speaking astronomy mailing list. Licandro works at the Isaac Newton Group of Telescopes and the Instituto de Astrofísica de Canarias, in Spain. They did it before with Sedna. But this time, by taking this 'doubtful' risk, they lost all the rights on the discovery of that object. Even more, their policy is, at least, criticizeable. Due to the detection of 2003 EL61 by Ortiz et. al., and

[meteorite-list] First Triple Asteroid System Found
http://www.berkeley.edu/news/media/releases/2005/08/10_sylvia.shtml UC Berkeley Press Release First triple asteroid system found By Robert Sanders 10 August 2005 BERKELEY - One of the thousands of asteroids orbiting the sun has been found to have a mini planetary system of its own. University of California, Berkeley, assistant research astronomer Franck Marchis and his colleagues at the Observatoire de Paris have discovered the first triple asteroid system - two small asteroids orbiting a larger one known since 1866 as 87 Sylvia. Because 87 Sylvia was named after Rhea Sylvia, the mythical mother of the founders of Rome, Marchis proposed naming the twin moons after those founders: Romulus and Remus. The International Astronomical Union (IAU) approved the names, to be announced in its Aug. 11 circular. Marchis and his colleagues will report their discovery in the Aug. 11 issue of the journal Nature simultaneously with an announcement that day at the Asteroid Comet Meteor conference in Armação dos Búzios, in the Brazilian state of Rio de Janeiro. The asteroid 87 Sylvia is one of the largest known from the asteroid main belt, which is located between the orbits of Mars and Jupiter. Shaped like a lumpy potato, Sylvia is about 280 kilometers (175 miles) in diameter and is located in the Cybele outer part of the belt, about 3.5 astronomical units (AU) from the sun. An AU is 93 million miles, the average distance between the sun and Earth.

Seventeen of these binary systems are in the main asteroid belt and have been imaged directly either by adaptive optics systems on large, ground-based telescopes or by the Hubble Space Telescope. Now, a second moon has been seen around Sylvia, making it a triple asteroid system. Sylvia's newly discovered moons orbit in nearly circular orbits in the same plane and direction (prograde) as the moon orbits the Earth. The closest moonlet, orbiting about 710 km (450 miles) from Sylvia, is Remus, a body only 7 km (4.4 miles) across and circling Sylvia every 33 hours. The second, Romulus, orbits at about 1360 km (860 miles), measures about 18 km (11.3 miles) across, and orbits in 87.6 hours. The asteroid Sylvia spins at a rapid rate, once every 5 hours and 11 minutes. People have been looking for multiple asteroid systems for a long time, because binary asteroid systems in the main belt seem to be common and formation scenarios, such as a collision between two asteroids followed by disruption and re-accretion, suggest that fragments should be orbiting bigger asteroids, Marchis said. I couldn't believe we found one. From two months' of observations of the moonlets' orbits, Marchis and his Paris colleagues were able to precisely calculate the mass and density of Sylvia, which shows it to be a rubble-pile asteroid, Marchis said. These asteroids are loose aggregations of rock presumably created when one asteroid smacked into another, disrupting one or both of them. A new asteroid formed later by accretion of large fragments from the disruption. The moonlets probably are debris left over from the collision that were gravitationally captured by the newly formed asteroid and which eventually settled into orbits around it. That's why most main-belt asteroids with companions have a rubble-pile structure, he said. Because of the scenarios of their formation, we expect to see more multiple asteroid systems like this. The density, 1.2 grams per cubic centimeter, is 20 percent higher than the density of water, which suggests it is composed of water, ice and rubble from a primordial asteroid, probably a hydrated carbonaceous chondrite, based on previous spectroscopic studies of the asteroid. It could be up to 60 percent empty space, said astronomer Daniel Hestroffer, one of three coauthors from the Institut de Mécanique Céleste et Calculs d'Éphémérides at the Observatoire de Paris. The discovery was made with one of the European Southern Observatory's 8-meter telescopes (Yepun) of the Very Large Telescope at Cerro Paranal, using the telescope's infrared camera and the high angular

The launch is scheduled for Thursday, August 11. The launch window is from 7:50 to 9:35 a.m. EDT. The launch was postponed for 24 hours due to a failure of a Redundant Rate Gryo Unit (RRGU) at the manufacturer. The unit is similar to two RRGU's that are part of the flight control system on MRO's Atlas V launch vehicle. The decision to go ahead with Thursday's launch was made today by launch vehicle engineers following test and evaluation of the failed RRGUs at the manufacturer. Similar units on the Atlas V at the Cape Canaveral Air Force Station Complex 41 were deemed acceptable for MRO's launch. For interested media, the imagery opportunity for the Atlas V rollout from KSC's Vertical Integration Facility to the launch pad departs from the KSC Press Site at 10:15 p.m. EDT tonight. On launch day, Aug. 11, 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.

[meteorite-list] RE: First Triple Asteroid System Found
Hi, Besides being delightful in itself, the first thing I thought of was that low-eccentricity, co-planar satellite orbits have long been regarded as a proof of formation in place, as in the Gallilean satellites of Jupiter, which I, in contrast, believe are captured Plutonian planets, just to keep riding my newest hobby-horse. Well, it's hardly likely that Old Sylvie is the center of her own little solar system! So, such orbits don't prove very much as to how they were formed, it seems. The second thought was: do you suppose that, in addition to a satellite system, Sylvie the Asteroid has an Asteroid Zone of her own? This falls into the really confusing category right next to Why does Pluto, an anthropormorphized cartoon dog, have another, less- human cartoon dog as a pet? Only partly in humor, but semi-seriously, too, I suggest a sensitive infra-red image search could reveal a ring of smaller bodies or particles around 87 Sylvia, orbiting in that same plane... Seriously, the low-eccentricity, co-planar satellite orbits argue a lack of perturbations and a long residence for these satellites. Sterling --- Rubble-Pile Minor Planet Sylvia and Her Twins VLT NACO Instrument Helps Discover First Triple Asteroid One of the thousands of minor planets orbiting the Sun has been found to have its own mini planetary system. Astronomer Franck Marchis (University of California, Berkeley, USA) and his colleagues at the Observatoire de Paris (France) [1] have discovered the first triple asteroid system - two small asteroids orbiting a larger one known since 1866 as 87 Sylvia [2]. Since double asteroids seem to be common, people have been looking for multiple asteroid systems for a long time, said Marchis. I couldn't believe we found one. The discovery was made with Yepun, one of ESO's 8.2-m telescopes of the Very Large Telescope Array at Cerro Paranal (Chile), using the outstanding image' sharpness provided by the adaptive optics NACO instrument. Via the observatory's proven Service Observing Mode, Marchis and his colleagues were able to obtain sky images of many asteroids over a six-month period without actually having to travel to Chile. One of these asteroids was 87 Sylvia, which was known to be double since 2001, from observations made by Mike Brown and Jean-Luc Margot with the Keck telescope. The astronomers used NACO to observe Sylvia on 27 occasions, over a two-month period. On each of the images, the known small companion was seen, allowing Marchis and his French colleagues to precisely compute its orbit. But on 12 of the images, the astronomers also found a closer and smaller companion. 87 Sylvia is thus not double but triple! Because 87 Sylvia was named after Rhea Sylvia, the mythical mother of the founders of Rome, Marchis proposed naming the twin moons after those founders: Romulus and Remus. The International Astronomical Union approved the names. Sylvia's moons are considerably smaller, orbiting in nearly circular orbits and in the same plane and direction. The closest and newly discovered moonlet, orbiting about 710 km from Sylvia, is Remus, a body only 7 km across and circling Sylvia every 33 hours. The second, Romulus, orbits at about 1360 km in 87.6 hours and measures about 18 km across. The asteroid 87 Sylvia is one of the largest known from the asteroid main belt, and is located about 3.5 times further away from the Sun than the Earth, between the orbits of Mars and Jupiter. The wealth of details provided by the NACO images show that 87 Sylvia is shaped like a lumpy potato, measuring 380 x 260 x 230 km and spinning at a rapid rate, once every 5 hours and 11 minutes. The observations of the moonlets' orbits allow the astronomers to precisely calculate the mass and density of Sylvia. With a density only 20% higher than the density of water, it is likely composed of water ice and rubble from a primordial asteroid. It could be up to 60 percent empty space, said co-discoverer Daniel Hestroffer (Observatoire de Paris, France). It is most probably a rubble-pile asteroid, Marchis added. These asteroids are loose aggregations of rock, presumably the result of a collision. Two asteroids smacked into each other and got disrupted. The new rubble-pile asteroid formed later by accumulation of large fragments while the moonlets are probably debris left over from the collision that were captured by the newly formed asteroid and eventually settled into orbits around it. Because of the way they form, we expect to see more multiple asteroid systems like this. Marchis and his colleagues will report their discovery in the August 11 issue of the journal Nature, simultaneously with an announcement that day at the Asteroid Comet Meteor conference in Armação dos Búzios, Rio de Janeiro state, Brazil.
