Re: [meteorite-list] Meteorite-list Digest, Vol 138, Issue 15
Howdy, all I¹ve examined this event and I don¹t agree that this feature is a debris cloud. It is visible in radar imagery about 15 minutes prior to the eyewitness accounts of sonic booms. It is also missing some of the diagnostic features of a meteorite fall, namely internal turbulence that fades within minutes of the event, high-altitude signatures, a sequential appearance due to size sorting of falling debris, and other features in the various radar data products. This feature moves laterally the whole time it is visible and appears prior to the event; looks like weather to me. There is a feature just NE of Shreveport that is interesting but not conclusively a meteorite fall. There are turbulence features seen in the Shreveport radar and reflectivity features seen at long range from the Fort Polk radar. I¹m not convinced that these features are related either, but we are talking them over. One feature of this event that troubles me is that there aren¹t any eyewitness reports on the AMS reporting page. Even though the area was overcast, an event of this magnitude should have been visible over a very large area. In the past, events like this have turned out to be man-made events coming from something on the ground.

Re: [meteorite-list] Meteorite-list Digest, Vol 138, Issue 15
Mike, Yes of course I know. All of the reports and the witnesses I spoke with said that this was NOT a sonic boom from an aircraft. One witness x-military AF said not aircraft. One report from TX is 35 miles from Shreveport... a bit far for an aircraft sonic boom to travel. The military claims that is was not them. Pipelines and factories all checked clean. Munition storage AFAWK all negative. The only fact we know is that there was a loud pop/ing followed by a rumbling loud boom that lasted up to 15 seconds. Windows rattled on w /NW sides of houses. There was no weather with conditions to produce thunder. So for now we have the NWS saying debris trail but odd... 1000 feet to 1500 feet rising; very low and they seem to be indicating, although not saying from a ground event??. And we have Marc saying that the NWS debris is not debris and was there in the same location prior to the event. Any NOTAMs for the area? at that time? I dont know and didnt check AND very unlikely. So this leaves us with an UBO - Unknown Booming Object or UBE - Event. Me thinks that someone knows or should know but are not saying for good reasons.

[meteorite-list] NASA's Hubble Telescope Finds Potential Kuiper Belt Targets for New Horizons Pluto Mission
October 15, 2014 NASA's Hubble Telescope Finds Potential Kuiper Belt Targets for New Horizons Pluto Mission Peering out to the dim, outer reaches of our solar system, NASA's Hubble Space Telescope has uncovered three Kuiper Belt objects (KBOs) the agency's New Horizons spacecraft could potentially visit after it flies by Pluto in July 2015. The KBOs were detected through a dedicated Hubble observing program by a New Horizons search team that was awarded telescope time for this purpose. This has been a very challenging search and it's great that in the end Hubble could accomplish a detection - one NASA mission helping another, said Alan Stern of the Southwest Research Institute (SwRI) in Boulder, Colorado, principal investigator of the New Horizons mission. The Kuiper Belt is a vast rim of primordial debris encircling our solar system. KBOs belong to a unique class of solar system objects that has never been visited by spacecraft and which contain clues to the origin of our solar system. The KBOs Hubble found are each about 10 times larger than typical comets, but only about 1-2 percent of the size of Pluto. Unlike asteroids, KBOs have not been heated by the sun and are thought to represent a pristine, well preserved deep-freeze sample of what the outer solar system was like following its birth 4.6 billion years ago. The KBOs found in the Hubble data are thought to be the building blocks of dwarf planets such as Pluto. The New Horizons team started to look for suitable KBOs in 2011 using some of the largest ground-based telescopes on Earth. They found several dozen KBOs, but none was reachable within the fuel supply available aboard the New Horizons spacecraft. We started to get worried that we could not find anything suitable, even with Hubble, but in the end the space telescope came to the rescue, said New Horizons science team member John Spencer of SwRI. There was a huge sigh of relief when we found suitable KBOs; we are 'over the moon' about this detection. Following an initial proof of concept of the Hubble pilot observing program in June, the New Horizons Team was awarded telescope time by the Space Telescope Science Institute for a wider survey in July. When the search was completed in early September, the team identified one KBO that is considered definitely reachable, and two other potentially accessible KBOs that will require more tracking over several months to know whether they too are accessible by the New Horizons spacecraft. This was a needle-in-haystack search for the New Horizons team because the elusive KBOs are extremely small, faint, and difficult to pick out against a myriad background of stars in the constellation Sagittarius, which is in the present direction of Pluto. The three KBOs identified each are a whopping 1 billion miles beyond Pluto. Two of the KBOs are estimated to be as large as 34 miles (55 kilometers) across, and the third is perhaps as small as 15 miles (25 kilometers). The New Horizons spacecraft, launched in 2006 from Florida, is the first mission in NASA's New Frontiers Program. Once a NASA mission completes its prime mission, the agency conducts an extensive science and technical review to determine whether extended operations are warranted. The New Horizons team expects to submit such a proposal to NASA in late 2016 for an extended mission to fly by one of the newly identified KBOs. Hurtling across the solar system, the New Horizons spacecraft would reach the distance of 4 billion miles from the sun at its farthest point roughly three to four years after its July 2015 Pluto encounter. Accomplishing such a KBO flyby would substantially increase the science return from the New Horizons mission as laid out by the 2003 Planetary Science Decadal Survey. The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA's Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy, Inc., in Washington. The Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland, manages the New Horizons mission for NASA's Science Mission Directorate. APL also built and operates the New Horizons spacecraft.

[meteorite-list] MESSENGER Provides First Optical Images of Ice Near Mercury's North Pole
http://messenger.jhuapl.edu/news_room/details.php?id=266 MESSENGER Mission News October 15, 2014 MESSENGER Provides First Optical Images of Ice Near Mercury's North Pole NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft has provided the first optical images of ice and other frozen volatile materials within permanently shadowed craters near Mercury's north pole. The images not only reveal the morphology of the frozen volatiles, but they also provide insight into when the ices were trapped and how they've evolved, according to an article published today http://geology.geoscienceworld.org/cgi/reprint/G35916.1v1?ijkey=rxQlFflgdo/rYkeytype=refsiteid=gsgeology in the journal, /Geology/. Two decades ago, Earth-based radar images of Mercury revealed the polar deposits, postulated to consist of water ice. That hypothesis was later confirmed by MESSENGER through a combination of neutron spectrometry, thermal modeling, and infrared reflectometry. But along with confirming the earlier idea, there is a lot new to be learned by seeing the deposits, said lead author Nancy Chabot, the Instrument Scientist for MESSENGER's Mercury Dual Imaging System (MDIS) and a planetary scientist at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. Beginning with MESSENGER's first extended mission in 2012, scientists launched an imaging campaign with the broadband clear filter of MDIS's wide-angle camera (WAC). Although the polar deposits are in permanent shadow, through many refinements in the imaging, the WAC was able to obtain images of the surfaces http://messenger.jhuapl.edu/gallery/sciencePhotos/image.php?image_id=1484 of the deposits by leveraging very low levels of light scattered from illuminated crater walls. It worked in spectacular fashion, said Chabot. The team zeroed in on Prokofiev http://messenger.jhuapl.edu/gallery/sciencePhotos/image.php?image_id=1478, the largest crater in Mercury's north polar region found to host radar-bright material. Those images show extensive regions with distinctive reflectance properties, Chabot said. A location interpreted as hosting widespread surface water ice exhibits a cratered texture indicating that the ice was emplaced more recently than any of the underlying craters. In other areas, water ice is present, she said, but it is covered by a thin layer of dark material inferred to consist of frozen organic-rich compounds. In the images of those areas http://messenger.jhuapl.edu/gallery/sciencePhotos/image.php?image_id=1485, the dark deposits display sharp boundaries. This result was a little surprising, because sharp boundaries indicate that the volatile deposits at Mercury's poles are geologically young, relative to the time scale for lateral mixing by impacts, said Chabot. One of the big questions we've been grappling with is 'When did Mercury's water ice deposits show up?' Are they billions of years old, or were they emplaced only recently? Chabot said. Understanding the age of these deposits has implications for understanding the delivery of water to all the terrestrial planets, including Earth. Overall, the images indicate that Mercury's polar deposits either were delivered to the planet recently or are regularly restored at the surface through an ongoing process. The images also reveal a noteworthy distinction between the Moon and Mercury, one that may shed additional light on the age of the frozen deposits. The polar regions of Mercury show extensive areas that host water ice, but the Moon's polar regions -- which also have areas of permanent shadows and are actually colder -- look different, Chabot said. One explanation for differences between the Moon and Mercury could be that the volatile polar deposits on Mercury were recently emplaced, according to the paper. If Mercury's currently substantial polar volatile inventory is the product of the most recent portion of a longer process, then a considerable mass of volatiles may have been delivered to the inner Solar System throughout its history. That's a key question, Chabot said. Because if you can understand why one body looks one way and another looks different, you gain insight into the process that's behind it, which in turn is tied to the age and distribution of water ice in the Solar System. This will be a very interesting line of inquiry going forward. MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) is a NASA-sponsored scientific investigation of the planet Mercury and the first space mission designed to orbit the planet closest to the Sun. The MESSENGER spacecraft was launched on August 3, 2004, and entered orbit about Mercury on March 17, 2011 (March 18, 2011 UTC), to begin a yearlong study of its target planet. MESSENGER's first extended mission began on March 18, 2012, and ended one year later. MESSENGER is now in a second extended mission,

[meteorite-list] Rosetta's Comet Landing Site Close Up
http://www.jpl.nasa.gov/news/news.php?feature=4339 Rosetta's Comet Landing Site Close Up Jet Propulsion Laboratory October 15, 2014 A mosaic from the European Space Agency's Rosetta spacecraft shows Site J, the primary landing site on comet 67P/Churyumov-Gerasimenko for the mission's Philae lander. Rosetta is the first mission to attempt a soft landing on a comet. The mosaic comprises two images taken by Rosetta's OSIRIS narrow-angle camera on Sept. 14, 2014, from a distance of about 19 miles (30 kilometers). The image scale is 1.6 feet (0.5 meters) per pixel. The red ellipse is centered on the landing site and is approximately 1,600 feet (500 meters) in diameter. Site J is located on the smaller of the comet's two lobes. On Nov. 12, the Rosetta spacecraft will release Philae at 01:03 a.m. PST/10:03 CET/09:03 UTC (the time the signal is received on Earth). Touchdown of Philae on Site J is expected about seven hours later, at around 8 a.m. PST/17:00 CET/16:00 UTC (Earth Received Time). Launched in March 2004, Rosetta was reactivated in January 2014 after a record 957 days in hibernation. Composed of an orbiter and lander, Rosetta's objectives since arriving at comet 67P/Churyumov-Gerasimenko earlier this month have been to study the celestial object up close in unprecedented detail, prepare for landing a probe on the comet's nucleus in November, and following the landing, track the comet's changes as it sweeps past the sun. Comets are time capsules containing primitive material left over from the epoch when the sun and its planets formed. Rosetta's lander will obtain the first images taken from a comet's surface and will provide comprehensive analysis of the comet's possible primordial composition by drilling into the surface. Rosetta also will be the first spacecraft to witness at close proximity how a comet changes as it is subjected to the increasing intensity of the sun's radiation. Observations will help scientists learn more about the origin and evolution of our solar system and the role comets may have played in seeding Earth with water, and perhaps even life. Rosetta is a European Space Agency mission with contributions from its member states and NASA. Rosetta's Philae lander is provided by a consortium led by the German Aerospace Center, Cologne; Max Planck Institute for Solar System Research, Gottingen; National Center of Space Studies of France (CNES), Paris; and the Italian Space Agency, Rome. NASA's Jet Propulsion Laboratory in Pasadena, California, a division of the California Institute of Technology, manages the U.S. participation in the Rosetta mission for NASA's Science Mission Directorate in Washington.

[meteorite-list] Fw: [Geology2] Meteorite fragments discovered 20 years after bolide event in Czech Republic
www.sciencedaily.com/releases/2014/10/141014142736.htm Meteorite fragments discovered 20 years after bolide event in Czech Republic Date: October 14, 2014 Source: Astronomy Astrophysics Summary: Scientists have discovered meteorite fragments 20 years after the corresponding bolide was seen in the skies of the Czech Republic. This discovery was made possible by reanalyzing the trajectory, which moved the impact line by 330 meters. Interestingly, the meteorites found on the ground are of different types, pointing to a parent asteroid of heterogeneous composition. First three Benešov meteorites found in April 2011, with metal detectors. From left to right: H5 chondrite of 1.56 g, LL3.5 chondrite of 7.72 g with achondrite clast, and LL3.5 chondrite of 1.99 g [2]. Credit: Image courtesy of Astronomy Astrophysics Astronomy Astrophysics is publishing the spectacular discovery of meteorite fragments 20 years after the corresponding bolide was seen in the skies of the Czech Republic. This discovery was made possible by reanalyzing the trajectory, which moved the impact line by 330 meters. Interestingly, the meteorites found on the ground are of different types, pointing to a parent asteroid of heterogeneous composition. Collisions of meter-sized meteoroids with Earth's atmosphere are relatively rare, occurring about 40 times a year. They cause very spectacular events, known as superbolides. One of the best known such events, the Benešov bolide, occurred on 7 May 1991 at 23h 03m 46s UT over the Czech Republic. It was recorded during systematic photographic observations by the European Fireball Network and certainly ended in a multiple meteorite fall, but no meteorite was found in the weeks and years after the fall, despite many attempts. In February 2011, nearly 20 years after the event, P. Spurný and his colleagues [1] measured the records again and analyzed the data with improved methods. This led to a new picture of the whole event with a revised atmospheric trajectory and a new impact location. This allowed the team to recover the Benešov meteorites, 20 years after the fall, exactly in the newly predicted area. It is the first time a meteorite is found so long after the bolide observation. The team found four small, highly-weathered meteorites with a total mass of 12 g. The probability that these four fragments come from different meteoroids and were found by chance at the same place is estimated to be 1 in 100,000 or less. Even more interestingly, these four meteorites are of three different mineralogical types. This means that the Benešov meteoroid was heterogeneous and contained at least three different types of material. After the Almahata Sitta fall, this is the second time that such a heterogeneous composition has been found. It raises the possibility that a significant fraction of all asteroids are heterogeneous and that they were strongly reprocessed by collisions with other asteroids in the main belt.

After the Almahata Sitta fall, this is the second time that such a heterogeneous composition has been found. It raises the possibility that a significant fraction of all asteroids are heterogeneous and that they were strongly reprocessed by collisions with other asteroids in the main belt.

Regardless, it would take far more evidence to suggest such a thing, not desert varnished ancient meteorites supposedly found only 20 years after a fall. No one in their right mind would think these are only 20 years old.

[meteorite-list] ad* MURCHISON with a unique history and documented provenance
Hello List, The following is a brief account of a story about a Murchison meteorite, an adventure, and a mission to promote world peace. It is also an ad to sell some Murchison part slices with a unique history and documented provenance. http://meteoriteusa.com/murchison.htm *** DeVere Baker was an explorer and adventurer born in 1915 to Mormon parents in Utah. He developed a love for the water and built a shipyard in California that did work for the US Navy during WWII. He had the goal of sailing the ocean currents on a raft to prove that writings in the Book of Mormons were true about possible voyages over long distances on rafts. Over the years he built a series of 5 rafts each named Lehi (after the prophet) with the idea of sailing from California to Hawaii. The Lehi IV set sail July 5th, 1958 from Redondo Beach with four crew plus Tangaroa (the dog). Despite storms, heavy winds and shark encounters the raft stayed on track, easily demonstrating, as others have done, that one can live at sea off rainwater and fish for long periods. After a total of 69 days of sailing some 2100 miles across the northern Pacific, Baker and his small crew made landfall in Maui in the Hawaiian islands. Baker became a celebrity after the successful raft journey. He started touring and giving lectures on world peace and his spiritual beliefs. In 1970 he visited the area around Victoria, Australia to promote a film he made about sailing on his rafts and he heard about the Murchison meteorite that fell there a year earlier. Baker’s grandson, Greg Ballard was with him in Australia and when they stopped at a rest stop / park area near Murchison. Greg decided to look for pieces of the meteorite. Greg said it didn't take long for him to stumble across a softball sized rock that appeared to be what his grandfather was looking for. His grandfather immediately recognized it for what it was and took the meteorite from him to use to further his cause in promoting world peace. During this trip, Captain Baker was given another piece of Murchison by a young Australian girl named Ellen Castle to also help his cause for world peace. Later, Captain Baker cut a piece off of the meteorite that Greg found, bringing its weight to 569 grams. In 1972 he donated a piece to Brigham Young University. This piece was either the slice from Greg's find or the fragment from Miss Castle. The remainder of the meteorite was given back to Greg from his grandfather's estate in 1990. DeVere Baker wrote several books including “The Raft Dog”, about his experience drifting to Hawaii, “The Intruder”, about his Murchison meteorite, and “Quetara” a book about a beautiful alien female. These three books were combined to create another book called The Raft, The Meteorite and a Dog! In March of 2014, I got a call from Greg Ballard in California and he told me he had a Murchison meteorite that he had found in Australia and would I be interested in buying it. When he said it was “larger than a softball”, I told him that indeed if it was Murchison, it was quite valuable. Over the next several months Greg and I worked out an agreement where I arranged for the purchase of part of the meteorite, with him giving the balance of it to a public non-profit foundation for donation to two Museums in North Carolina. I was recently able to take some slices from the meteorite for resale to offset some of the costs of the purchase. Since the meteorite had been cut before I received it, I was comfortable with taking some additional slices from it. Cutting and polishing the rough side where it was originally cut, improved its appearance greatly. Greg gave me permission to use his grandfather’s writings and pictures in displaying and telling the story of the Murchison. Included with each slice purchased are copies of pictures and descriptions of the Murchison and its history since found in 1970. Plus copies of two letters sent to Captain Baker in 1958 and 1961. Taking into consideration the cost of the meteorite, the cost of cutting, the cut loss, the history, the provenance and that most of the meteorite is going to museums, consider the value of owning a slice of this meteorite. I'm limited in the amount of this meteorite that I can offer to collectors. Thank you for taking time to visit my webpage about this Murchison and the related information and pictures. http://meteoriteusa.com/murchison.htm John MeteoriteUSA.com __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list

Eucritic inclusions in Vaca Muerta as well. But there aren't too many meteorites that have different specimens with different petrologic classes, unless it's a clast or xenolith that weathered out of a host specimen.

Interestingly, the meteorites found on the ground are of different types, pointing to a parent asteroid of heterogeneous composition. Collisions of meter-sized meteoroids with Earth's atmosphere are relatively rare, occurring about 40 times a year. They cause very spectacular events, known as superbolides. One of the best known such events, the Benešov bolide, occurred on 7 May 1991 at 23h 03m 46s UT over the Czech Republic. It was recorded during systematic

Re: [meteorite-list] Meteorite-list Digest, Vol 138, Issue 17
Hi all, Pavel Spurny and his team are considered to be among the world's experts in instrumentally observed bolides. Before dismissing this story as a scam based on a single image, you may wish to read the paper in its entirety: http://www.aanda.org/articles/aa/pdf/2014/10/aa24308-14.pdf paying special attention to the local conditions where the meteorites were found. 20 years of being repeatedly tilled under farmland soil in a wet European climate is hard on meteorites. These were also thought to be meteorites that came from a violent, low-altitude disruption, so even if they initially had fusion crust or typical meteorite shapes, 20 years in the ground would have likely significantly altered their appearance.

Re: [meteorite-list] Meteorite-list Digest, Vol 138, Issue 17
Hi Eric, I don't think anyone is questioning the integrity of the scientists involved. Rather, there are two obvious problems that are raised by that single image : 1) the presence of what appears to be desert varnish on the stones - a process not seen in meteorites from non-desert locales. Weathering in wet climes typically produces an appearance quite different from the glossy varnish seen on these stones. 2) the presence of two different petrologic types from the same fall. In the case of #1, appearances can be deceiving, so that may not be desert varnish, although it certainly looks like it. Perhaps someone with expertise in this area can comment (i.e. Dr. Garvie). In the case of #2, multiple types from the same fall is not unheard of, but is very rare. I will read the entire paper though, out of curiosity, and perhaps it can clarify these points.
