[meteorite-list] Stardust Lands in London - Scientists Look to Comet for Vital Clues about Solar System
http://www.imperial.ac.uk/P7454.htm Stardust lands in London: scientists look to comet for vital clues about Solar System Imperial College - London For immediate release 8 February 2006 Dust from a distant comet arrived in London today enabling UK scientists to be among the first to take a close look at the samples. The dust from comet Wild-2 was collected after a three billion mile round-trip by the NASA Stardust probe, which began in 1999. The return of samples from the Stardust mission gives a small group of London scientists the opportunity to find out whether comets, mysterious objects that have puzzled humans for millennia, record the very earliest history of our Solar System. The samples will also enable them to investigate the theory that comets may have provided our planet with some of the water and organic material that allowed life to develop. Although detailed analyses will take months or even years, it is possible that fundamental new data could be uncovered in a matter of hours. Dr Phil Bland, a planetary scientist from Imperial College London's Department of Earth Sciences and Engineering, will be analysing the material using an X-ray instrument capable of analysing the mineral content of the tiny particles while they are still in the collector material, without damaging them. Comets contain a record of the earliest stages of Solar System formation. These tiny grains could be a big part of the puzzle of how planets formed from dust and gas. It's a resource that will keep us busy for a long time, but we might get answers to some questions for instance, whether comets contain minerals associated with water in a matter of hours, he said. Dr Matt Genge, an expert on extraterrestrial dust who is also from the Department of Earth Sciences and Engineering, added: I've looked at thousands of exterrestrial dust particles over the years but it's tremendously exciting to have bits of known comet quite literally at the tips of our fingers. Not since the Apollo days have we had the opportunity to look at material brought back from space. These few thousands of a gram of dust may tell us more about comets than the last 100 years of telescope observations. The results of the London scientists' analysis of the comet dust will be published together with those from the rest of the international Preliminary Evaluation Team, later this year. Scientists Anton Kearsley and Gretchen Benedix at the Natural History Museum complete the London NASA team who will be analysing the samples. Imperial College and the Natural History Museum are working together on this project and an extensive range of other planetary science projects as part of the Impacts and Astromaterials Research Centre, which brings together scientists from both institutions. The X-ray machine was developed by researchers at the Natural History Museum and Imperial College and is funded by the Particle Physics and Astronomy Research Council and the Royal Society. -ends- For further information please contact: Laura Gallagher Press Officer Communications Division Tel: +44 (0)20 7594 6702 Mobile: +44 (0)7803 886 248 E-mail: [EMAIL PROTECTED] ac.uk __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] New Viewing Technique Bolsters Case For Life On Mars (Nakhla Meteorite)
http://www.spacedaily.com/reports/New_Viewing_Technique_Bolsters_Case_For_Life_On_Mars.html New Viewing Technique Bolsters Case For Life On Mars by Staff Writers SpaceDaily February 8, 2006 Houston, Texas (SPX) - New examinations of a Martian meteorite found nearly a century ago have strengthened the possibility that the red planet once harbored life. I don't understand the sample completely just yet, but it's exciting, research team member Kathie Thomas-Keprta told SpaceDaily.com. The sample in question is from a meteorite named Nakhla, which was found in the Egyptian desert in 1911, and which has been held since by the Natural History Museum in London. A new examination of Nakhla has produced a very strong indication that it might have been imbedded with organic carbon - an absolute necessity for life - that did not originate on Earth. Keprta, a specialist in microscopy techniques and a contractor for NASA at the Johnson Space Center, said she and colleagues recently obtained pristine samples of the rock -which is thought to be 1.3 billion years old - to probe its structure using the latest optical examination techniques. We have known for a long time about its carbon content via chemical analysis, she explained, but up to now no one has been able to locate it. The team took a tiny, polished piece of the meteorite only 30 micrometers thick that was sealed in epoxy and applied a technique called focused-ion-beam microscopy, or FIB, to carve out a small rectangle from the sample, and another technique called transmission electron microscopy, or TEM, to identify the deposits of carbonaceous material. For the first time, we can find the exact area on Nakhla that harbors the carbon, Thomas-Keprta said. Further analysis by secondary ion mass spectroscopy, or SIMS, identified the sample as composed of carbon 13, which she said could only have come from an extraterrestrial source, not from any earthbound contamination. All life on Earth contains some quantity of the isotope carbon 14, but no carbon 13. The deposits, which Thomas-Keprta described as shrubby, resemble similar structures on Earth created by the actions of ancient microorganisms that lived within volcanic rocks on the ocean floor. Thomas-Keprta and colleagues will present their findings next month at the Lunar and Planetary Science Conference in Houston. The team includes scientists who also presented evidence for microbial life in another Martian meteorite - ALH84001, which was found in Antarctica - in 1998. All Martian meteorites are thought to have been ejected from the red planet's surface during ancient impacts. The meteorites drifted in interplanetary space until captured by Earth's gravity and dragged down to the surface.

[meteorite-list] UH Hilo Joins Hunt for Killer Asteroids
Institute for Astronomy University of Hawaii Honolulu, Hawaii Contacts: Dr. Nick Kaiser Institute for Astronomy University of Hawaii at Manoa 1-808-520-3680 Dr. Robert Fox Physics Astronomy Department University of Hawaii at Hilo 1-808-974-7731 Mrs. Karen Rehbock Assistant to the Director Institute for Astronomy University of Hawaii 1-808-956-6829 For immediate release: February 7, 2006 UH Hilo Joins Hunt for Killer Asteroids Astrophysicists at the University of Hawaii at Hilo have become partners in the Pan-STARRS project, an observatory to search the sky for dangerous asteroids and other unexpected celestial events. The prototype telescope, with a single 70-inch-diameter mirror, is currently under construction on Haleakala and will shortly be outfitted with the world's largest digital camera, a device with 1.4 billion pixels. The full Pan-STARRS observatory, which is expected to be completed in 2009, will have four such mirrors and will survey the whole sky several times each month. Scientists on the Hilo campus will contribute both to the development of the system and to reaping the scientific rewards that will follow once the observatory becomes operational. Students and faculty at UH Hilo will also be active in spreading the word of the educational opportunities arising from the project in the local community and will develop material that can be used in high schools to promote the project. The project capitalizes on expertise in developing astronomical detectors at the University of Hawaii's Institute for Astronomy in Manoa, where experts are working with MIT's Lincoln Laboratory to develop the new detectors. The data will be processed with the help of the Maui High Performance Computer Center (MHPCC) on Maui, and data will be made available to the community via a database being developed by partner Science Applications International Corporation (SAIC). The final system is planned to replace the University's 36-year-old 2.2-meter (88-inch) telescope on Mauna Kea. Institute for Astronomy Director Dr. Rolf Kudritzki said, Pan-STARRS is the first major telescope facility to be developed by the IfA in several decades. It leverages the unique features of Hawaiian observing sites which deliver the sharpest images on the planet, as well as the enormous strengths in both technological and scientific skills that have been built up at the University. Larger telescopes on Mauna Kea will be used to follow up the discoveries of Pan-STARRS. A major goal of Pan-STARRS is to discover and characterize Earth-approaching objects, both asteroids and comets, that might pose a danger to our planet. However, the huge volume of images produced by this system will provide valuable data for many other kinds of scientific programs. The system will generate up to 10 terabytes (10 million megabytes) of data per night, and these data will be used to generate a multicolor digital atlas of the entire sky as seen from Hawaii. Dr. Nick Kaiser, leader of the project says, By being able to scan the sky so rapidly and repeatedly, this observatory will open up a whole range of new possibilities in 'time-domain astronomy.' It will make enormous numbers of discoveries of moving objects like asteroids, variable stars and transients like supernovae and hypernovae. The data will be used to map the dark matter in the Universe, and also to characterize the mysterious 'dark energy' that is driving the universal expansion. We welcome the participation of our colleagues and students from UH Hilo, said Dr. Kaiser, emphasizing the importance the University of Hawaii places on educating Hawaii's students. UH Hilo Physics Department Chair Dr. Robert Fox says, Our involvement with Pan-STARRS greatly expands UH Hilo's ability to provide a unique astronomy education on the slopes of one of the world¹s premier observational sites. The Institute for Astronomy at the University of Hawaii conducts research into galaxies, cosmology, stars, planets, and the sun. Its faculty and staff are also involved in astronomy education, deep space missions, and in the development and management of the observatories on Haleakala and Mauna Kea.

[meteorite-list] Kaboom! Ancient Impacts Scarred Moon To Its Core, May Have Created 'Man in the Moon'
Research Communications Ohio State University Contact: Laramie Potts, (614) 292-7365 Ralph von Frese, (614) 292-5635 Written by Pam Frost Gorder, (614) 292-9475 2/8/06 KABOOM! ANCIENT IMPACTS SCARRED MOON TO ITS CORE, MAY HAVE CREATED MAN IN THE MOON COLUMBUS , Ohio -- Ohio State University planetary scientists have found the remains of ancient lunar impacts that may have helped create the surface feature commonly called the man in the moon. Their study suggests that a large object hit the far side of the moon and sent a shock wave through the moon's core and all the way to the Earth-facing side. The crust recoiled -- and the moon bears the scars from that encounter even today. The finding holds implications for lunar prospecting, and may solve a mystery about how past impacts on Earth affect it's geology today. The early Apollo missions revealed that the moon isn't perfectly spherical. Its surface is warped in two spots; an earth-facing bulge on the near side is complemented by a large depression on the Moon's far side. Scientists have long wondered whether these surface features were caused by Earth's gravity tugging on the moon early in its existence, when its surface was still molten and malleable. According to Laramie Potts and Ralph von Frese, a postdoctoral researcher and professor of geological sciences respectively at Ohio State , these features are instead remnants from ancient impacts. Potts and von Frese came to this conclusion after they used gravity fluctuations measured by NASA's Clementine and Lunar Prospector satellites to map the moon's interior. They reported the results in a recent issue of the journal Physics of the Earth and Planetary Interiors. They expected to see defects beneath the moon's crust that corresponded to craters on the surface. Old impacts, they thought, would have left marks only down to the mantle, the thick rocky layer between the moon's metallic core and its thin outer crust. And that's exactly what they saw, at first. Potts pointed to a cross-sectional image of the moon that the scientists created using the Clementine data. On the far side of the moon, the crust looks as though it was depressed and then recoiled from a giant impact, he said. Beneath the depression, the mantle dips down as he and von Frese would expect it to do if it had absorbed a shock. Evidence of the ancient catastrophe should have ended there. But some 700 miles directly below the point of impact, a piece of the mantle still juts into the moon's core today. That was surprising enough. People don't think of impacts as things that reach all the way to the planet's core, von Frese said. But what they saw from the core all the way to the surface on the near side of the moon was even more surprising. The core bulges, as if core material was pushed in on the far side and pulled out into the mantle on the near side. Above that, an outward-facing bulge in the mantle, and above that -- on the Earth-facing side of the moon -- sits a bulge on the surface. To the Ohio State scientists, the way these features line up suggests that a large object such as an asteroid hit the far side of the moon and sent a shock wave through the core that emerged on the near side. The scientists believe that a similar, but earlier impact occurred on the near side. Potts and von Frese suspect that these events happened about four billion years ago, during a period when the moon was geologically active -- with its core and mantle still molten and magma flowing. Back then, the moon was much closer to the Earth than it is today, Potts explained, so the gravitational interactions between the two were stronger. When magma was freed from the Moon's deep interior by the impacts, Earth's gravity took hold of it and wouldn't let go. So the warped surfaces on the near and far sides of the moon and the interior features that connect them are all essentially signs of injuries that never healed. This research shows that even after the collisions happened, the Earth had a profound effect on the moon, Potts said. The impacts may have created conditions that led to a prominent lunar feature. The man in the moon is a collection of dark plains on the Earth-facing side of the moon, where magma from the moon's mantle once flowed out onto the surface and flooded lunar craters. The moon has long since cooled, von Frese explained, but the dark plains are a remnant of that early active time -- a frozen magma ocean. How that magma made it to the surface is a mystery, but if he and Potts are right, giant impacts could have created a geologic hot spot on the moon -- a site where magma bubbles to the surface. Some time between when the impacts occurred and when the moon solidified, some magma escaped the mantle through cracks in the crust and flooded the nearside surface and formed a lunar hot spot. A hot spot on Earth forms the volcanoes that make the Hawaiian island

[meteorite-list] Asteroid Mining: Key to the Space Economy
http://www.space.com/adastra/060209_adastra_mining.html Asteroid Mining: Key to the Space Economy By Mark Sonter National Space Society 09 February 2006 The Near Earth Asteroids offer both threat and promise. They present the threat of planetary impact with regional or global disaster. And they also offer the promise of resources to support humanity's long-term prosperity on Earth, and our movement into space and the solar system. The technologies needed to return asteroidal resources to Earth Orbit (and thus catalyze our colonization of space) will also enable the deflection of at least some of the impact-threat objects. We should develop these technologies, with all due speed! Development and operation of future in-orbit infrastructure (for example, orbital hotels, satellite solar power stations, earth-moon transport node satellites, zero-g manufacturing facilities) will require large masses of materials for construction, shielding, and ballast; and also large quantities of propellant for station-keeping and orbit-change maneuvers, and for fuelling craft departing for lunar or interplanetary destinations. Spectroscopic studies suggest, and 'ground-truth' chemical assays of meteorites confirm, that a wide range of resources are present in asteroids and comets, including nickel-iron metal, silicate minerals, semiconductor and platinum group metals, water, bituminous hydrocarbons, and trapped or frozen gases including carbon dioxide and ammonia. As one startling pointer to the unexpected riches in asteroids, many stony and stony-iron meteorites contain Platinum Group Metals at grades of up to 100 ppm (or 100 grams per ton). Operating open pit platinum and gold mines in South Africa and elsewhere mine ores of grade 5 to 10 ppm, so grades of 10 to 20 times higher would be regarded as spectacular if available in quantity, on Earth. Water is an obvious first, and key, potential product from asteroid mines, as it could be used for return trip propulsion via steam rocket. About 10% of Near-Earth Asteroids are energetically more accessible (easier to get to) than the Moon (i.e. under 6 km/s from LEO), and a substantial minority of these have return-to-Earth transfer orbit injection delta-v's of only 1 to 2 km/s. Return of resources from some of these NEAs to low or high earth orbit may therefore be competitive versus earth-sourced supplies. Our knowledge of asteroids and comets has expanded dramatically in the last ten years, with images and spectra of asteroids and comets from flybys, rendezvous, and impacts (for example asteroids Gaspra, Ida, Mathilde, the vast image collection from Eros, Itokawa, and others; comets Halley, Borrelly, Tempel-1, and Wild-2. And radar images of asteroids Toutatis, Castalia, Geographos, Kleopatra, Golevka and other... These images show extraordinary variations in structure, strength, porosity, surface features. The total number of identified NEAs has increased from about 300 to more than 3,000 in the period 1995 to 2005. The most accessible group of NEAs for resource recovery is a subset of the Potentially Hazardous Asteroids (PHAs). These are bodies (about 770 now discovered) which approach to within 7.5 million km of earth orbit. The smaller subset of those with orbits which are earth-orbit-grazing give intermittently very low delta-v return opportunities (that is it is easy velocity wise to return to Earth). These are also the bodies which humanity should want to learn about in terms of surface properties and strength so as to plan deflection missions, in case we should ever find one on a collision course with us. Professor John Lewis has pointed out (in Mining the Sky) that the resources of the solar system (the most accessible of which being those in the NEAs) can permanently support in first-world comfort some quadrillion people. In other words, the resources of the solar system are essentially infinite? And they are there for us to use, to invest consciousness into the universe, no less. It's time for humankind to come out of its shell, and begin to grow!! So both for species protection and for the expansion of humanity into the solar system, we need to characterize these objects and learn how to mine and manage them. Once we learn how to work on, handle, and modify the orbits of small near-earth objects, we will have achieved, as a species, both the capability to access the vast resources of the asteroids, and also the capability to protect our planet from identified collision threats. Since the competing source of raw materials is delivery by launch from Earth, which imposes a launch cost per kilogram presently above $10,000 per kg, this same figure represents the upper bound of what recovered asteroidal material would be presently worth in low earth orbit. Future large scale economic activity in orbit is unlikely to develop however until launch cost drops to something in the range $500 to $1,000 per kilogram to LEO. At that point, any

[meteorite-list] fukang meteorite
Well after all the emails.After all the mention of looking for a piece of this meteorite,I came home with none.There were 4 meteorite dealers who had it forsale.They were selling it for between $12 and $20 a gram.And after hearing all the stories about it,there is ALOT of this stuff to go around.Bud eisler,mike farmer,Ann black,all had some forsale.But like I also heard,after a few months it will be lower than $10 a gram.The market will be flooded with this meteorite.But if you have not seen it,it is beautiful.It has the largest olivine crystals I have even seen.Esquel is still the king.Some fukang someday.But not today.I will just enjoy my new haag pieces.

Re: [meteorite-list] I need a scale cube
Hi Ingo and all who requested a cube. Most stated they would light one, ...if the price were right I looked through a massive pile of paperwork but can not find what I paid for these. Does anyone know what Niger Meteorite Recon were charging for each cube? I can't answer anyone's emails until I have this info.

Re: [meteorite-list] Strange two-tone rock on Mars
Mark and all, This really is a cool image. Thanks for bringing it to our attention. I'm guessing you might appreciate a serious reply or two. On earth, this is immediately reminiscent of a weathered lahar fragment. Volcanic mudflows involving big blocks in an ashy matrix are almost universal in the sorts of volcanic environments for which Mars holds all the solar system records. Add some wind ablation to sculpt both the block and the matrix, and this image depicts the result. This scenario would benefit from some liquid (water?) but could be seen in a dry pyroclastic ash flow. There are other possibilities, but this seem an obvious first guess for Mars.
