[meteorite-list] Catalog of the recovered Bassikounou masses released
We are pleased to announce that the Descriptive Catalog on the Recovered Masses of the Bassikounou Meteorite Fall is now available as a non-commercial download. The catalog lists 108 single masses of a combined weight of 62.186kg (including the 6.120kg main mass) individually and another 31.665kg in lots. More than 80 individual masses are pictured. The final TKW of the Bassikounou meteorite fall is 93.851kg. In the latest phase of this undertaking we have often been approached by collectors explaining that regarding to their observations the TKW should be much higher. To prove their point they showed us images of single Bassikounou meteorites or complete lots they were offered recently. In 99% of these cases we had cataloged the particular masses before either individually or under a certain lot. In this context it might be interesting for some of you, that many meteorites change hands already before they get distributed. Moroccan sellers equip their colleagues with commission material to visit Europe, or they simply exchange certain batches of material between one another. This is the reason why one and the same meteorite can be offered to you from different sellers from the same NWA country successively. During our research we were able to follow an exemplary Bassikounou mass on its journey from the local finder, to a distributor in Morroco, to a meteorite fair in France, to a European mineral dealer and finally to a collector in Canada. During the stations of the journey this particular meteorite was offered no less than 12 times under different circumstances and with different photos. This in mind it is no wonder that people think there is much more material circulating than actually is. Our experience lead us to the conclusion that many recent meteorite falls that produced showers are largely overestimated in their total weight. We hope that our investigation may aid the understanding and recovery of future meteorite falls in isolated areas. And we are positive, that our undertaking helps to sensitize finders as well as distributors in Mauritania and Morocco to preserve the information that is connected to the meteorites they trade.

An absolutely stunning piece of work, well done Svend and Matthias. I've only managed a quick browser through so far, but look forward to spending longer reading it later. It's enlightening to see this amount of detail regarding a fall and it's subsequent collection/distribution. Thanks for all your time and effort, Matt.

[meteorite-list] Mars Exploration Rover Update - July 2, 2007
http://marsrovers.jpl.nasa.gov/mission/status.html SPIRIT UPDATE: Spirit Independently Approaches and Studies A Rock Outcrop - sol 1234-1239, July 02, 2007: Spirit remains healthy after attempting to wrap up scientific studies on an outcrop that contains several tantalizing, high-silica targets. High-silica targets are of interest to scientists because water might have been involved in forming them. Spirit still has some work to do on two targets, known as Eileen Dean and Innocent Bystander, before moving on to the elevated, circular plateau known as Home Plate. On Spirit's 1,235th sol, or Martian day of exploration (June 24, 2007), the rover successfully completed Step 4 of a new computer sequence called IDD Autoplace. (IDD stands for Instrument Deployment Device, the technical name for the rover's robotic arm.) During the test, Spirit drove to a pre-selected target and autonomously gathered scientific data. The sequence enables the rover to select a substitute target of opportunity if the pre-selected target is out of range, which is exactly what happened during the first two tests. Over the next month, Spirit will collect data in support of future Mars rover missions by taking images of the Sun each day with the navigation camera. These images are being used to develop an alternate method for orienting the rover. Sol-by-sol summary: In addition to daily remote science observations of the atmosphere and terrain using the panoramic camera and the miniature thermal emission spectrometer, and communication activities including morning direct-from-Earth uplinks via the rover's high-gain antenna and evening downlinks at UHF frequencies via the Mars Odyssey orbiter, Spirit completed the following activities: Sol 1234 (June 23, 2007): Spirit acquired full-color images, using all 13 filters of the panoramic camera, of outcrop exposures known as Virginia Bell, Nancy Warren, and Innocent Bystander. The rover acquired panoramic camera images of a target known as Eileen Dean. Spirit surveyed several targets using the miniature thermal emission spectrometer, including Mary Dailey, NancyWarren3, Dolores Moore, Louella Daetweiler, NancyWarren_background, MaryDailey2, and Eileen Dean. Sol 1235: Upon awakening, Spirit surveyed the sky with the panoramic camera. Spirit then moved slightly closer to Eileen Dean. The rover completed Step 4 of the automatic targeting test by touching a spot that was offset from the target by about 5 centimeters (2 inches) with the Moessbauer spectrometer, acquiring a 1-by-1-by-seven mosaic of microscopic images, and placing the alpha-particle X-ray spectrometer on the spot and collecting data with the instrument. Spirit acquired navigation camera images and conducted a sky survey at low sun with the panoramic camera. Prior to the overpass of the Odyssey orbiter, the rover took images of the sky, known as sky flats, for calibration purposes. Sol 1236: Spirit used on-board software to watch for dust devils in addition to completing standard remote-science observations. Sol 1237: Spirit rotated in place toward Eileen Dean, completing a final yaw, or pivot, of 42.8 degrees. Working autonomously, Spirit touched Eileen Dean with the Moessbauer spectrometer, acquired a 1-by-1-by-7 mosaic of microscopic images of the target, and completed alpha-particle X-ray spectrometer studies on the target. Spirit acquired images with the navigation camera. Spirit examined the rover's external calibration target with the miniature thermal emission spectrometer to verify that there was no dust contamination on the mirror as a result of recent dust-cleaning events related to Martian winds. Spirit acquired full-color images, using all 13 filters of the panoramic camera, of the rover's solar arrays, also to characterize changes in dust accumulation on the surface. Prior to the overpass of the Odyssey spacecraft, Spirit observed the Sun with the navigation camera in support of the Mars Science Laboratory rover scheduled for launch in 2009. The goal of these observations is to see if navigation camera images of the sun can be used to orient the rover. Sol 1238: In the morning, Spirit monitored dust build-up on the rover's mast, surveyed the horizon with the panoramic camera, and acquired movie frames with the navigation camera in search of dust devils. Spirit acquired microscopic images of the solar arrays, capture magnet, and filter magnet to document dust levels since the most recent dust-cleaning events on sols 1233 and 1234 (June 22-23, 2007). The rover acquired microscopic images of Eileen Dean and collected data on the target using the alpha-particle X-ray spectrometer. Spirit acquired four sets of comparative measurements with the miniature thermal emission spectrometer early in the day, in the afternoon, overnight, and early the next sol. Spirit observed the Sun with the navigation camera in support of the Mars Science Laboratory rover scheduled for launch in 2009. The goal of these observations

Re: [meteorite-list] Catalog of the recovered Bassikounou masses released
Dear Svend and Mathias, I can't say it with any more appreciation and acclaim than everyone else who've already thanked you both for your extremely diligent, singular work on Bassikounou. Your Descriptive Catalog on the Recovered Masses of the Bassikounou Meteorite Fall is simply astounding! I immediately downloaded it, printed it, and I'm presently in the process, with excitement, digesting it all! Both your descriptive catalog and your account of the fall presented on your website will hopefully give impetus to those in the future to present such similar detail when researching and documenting subsequent falls and even finds for that matter when possible! I've printed out both works and placed them in a binder to sit along side my other reference materials. Danke sehr, Mal At 02:36 PM 7/3/2007 +0200, [EMAIL PROTECTED] wrote: We are pleased to announce that the Descriptive Catalog on the Recovered Masses of the Bassikounou Meteorite Fall is now available as a non-commercial download. The catalog lists 108 single masses of a combined weight of 62.186kg (including the 6.120kg main mass) individually and another 31.665kg in lots. More than 80 individual masses are pictured. The final TKW of the Bassikounou meteorite fall is 93.851kg. In the latest phase of this undertaking we have often been approached by collectors explaining that regarding to their observations the TKW should be much higher. To prove their point they showed us images of single Bassikounou meteorites or complete lots they were offered recently. In 99% of these cases we had cataloged the particular masses before either individually or under a certain lot. In this context it might be interesting for some of you, that many meteorites change hands already before they get distributed. Moroccan sellers equip their colleagues with commission material to visit Europe, or they simply exchange certain batches of material between one another. This is the reason why one and the same meteorite can be offered to you from different sellers from the same NWA country successively. During our research we were able to follow an exemplary Bassikounou mass on its journey from the local finder, to a distributor in Morroco, to a meteorite fair in France, to a European mineral dealer and finally to a collector in Canada. During the stations of the journey this particular meteorite was offered no less than 12 times under different circumstances and with different photos. This in mind it is no wonder that people think there is much more material circulating than actually is. Our experience lead us to the conclusion that many recent meteorite falls that produced showers are largely overestimated in their total weight. We hope that our investigation may aid the understanding and recovery of future meteorite falls in isolated areas. And we are positive, that our undertaking helps to sensitize finders as well as distributors in Mauritania and Morocco to preserve the information that is connected to the meteorites they trade.

[meteorite-list] NASA Gives Two Successful Spacecraft New Assignments (Stardust Deep Impact)
July 3, 2007 Grey Hautaluoma/Tabatha Thompson Headquarters, Washington 202-358-0668/3895 RELEASE: 07-147 NASA GIVES TWO SUCCESSFUL SPACECRAFT NEW ASSIGNMENTS WASHINGTON -- Two NASA spacecraft now have new assignments after successfully completing their missions. The duo will make new observations of comets and characterize extrasolar planets. Stardust and Deep Impact will use their flight-proven hardware to perform new, previously unplanned, investigations. These mission extensions are as exciting as it gets. They will allow us to revisit a comet for the first time, add another to the list of comets explored and make a search for small planets around stars with known large planets. And by using existing spacecraft in flight, we can accomplish all of this for only about 15 percent of the cost of starting a new mission from scratch, said Alan Stern, associate administrator for NASA's Science Mission Directorate, Headquarters, Washington. These new mission assignments for veteran spacecraft represent not only creative thinking and planning, but are also a prime example of getting more from the budget we have. The EPOXI mission melds two compelling science investigations -- the Deep Impact Extended Investigation (DIXI) and the Extrasolar Planet Observation and Characterization (EPOCh). Both investigations will be performed using the Deep Impact spacecraft, which finished its prime mission in 2005. DIXI will involve a flyby of comet Boethin, which has never been explored. Boethin is a small, short period comet, or one that returns frequently to the inner solar system, from beyond Jupiter's orbit. This investigation will allow the recovery of some of the science lost with the 2002 failure of the COmet Nucleus Tour (CONTOUR) mission that was designed to make comparative studies of multiple comets. DIXI will be targeted to fly by comet Boethin December 5, 2008. The EPOCh investigation also will use the Deep Impact spacecraft to observe several nearby bright stars, watching as the giant planets already known to be orbiting the stars pass in front of and then behind them. The collected data will be used to characterize the giant planets and to determine whether they possess rings, moons, or Earth-sized planetary companions. EPOCh's sensitivity will exceed both current ground and space-based observatory capabilities. EPOCh also will measure the mid-infrared spectrum of the Earth, providing comparative data for future efforts to study the atmospheres of extrasolar planets. This search for extrasolar planets will be made this year, en route to comet Boethin. Michael A'Hearn of the University of Maryland, College Park, is EPOXI's principal investigator and the leader of the DIXI science team. L. Drake Deming of NASA's Goddard Space Flight Center, in Greenbelt, Md., is EPOXI's deputy principal investigator and leads the EPOCh investigation. John Mather, Chief Scientist for NASA's Science Mission Directorate, said, EPOXI is a wonderful opportunity to add to our growing body of knowledge of exoplanets. Watching planets go behind or in front of their parent stars can tell us about their atmospheric chemistry. The other newly selected Discovery mission of opportunity is called New Exploration of Tempel 1 (NExT). The mission will reuse NASA's Stardust spacecraft to revisit comet Tempel 1. This investigation will provide the first look at the changes to a comet nucleus produced after its close approach to the sun. It will mark the first time a comet has ever been revisited. NExT also will extend the mapping of Tempel 1, making it the most mapped comet nucleus to date. This mapping will help address the major questions of comet nucleus geology raised by images of areas where it appears material might have flowed like a liquid or powder. The images were returned by Deep Impact from its encounter with the comet on July 4, 2005. NExt is scheduled to fly by Tempel 1 on Feb. 14, 2011. Joseph Veverka of Cornell University, Ithaca, NY, is NExT's principal investigator. Stardust launched in Feb. 7, 1999. It traveled over 2 billion miles to fly within 150 miles of the comet Wild 2 in January 2004 to bring back samples that may provide new insights into the composition of comets and how they vary from one another. The container with the comet samples returned to Earth in January 2006 while the rest of the spacecraft remained in space. Created in 1992, NASA's Discovery Program sponsors frequent, cost-capped solar system exploration missions with highly focused scientific goals. In 2006, NASA received approximately two dozen proposals in response to an Announcement of Opportunity for Discovery missions and Missions of Opportunity. Proposals were evaluated for scientific merit, technical, management and cost feasibility.

[meteorite-list] FS: Uruacu Whole Specimens
My 1975 gram end cut sold really fast so I figured it it would be a good time to list the 7 whole specimens I have available for $1 per gram They range from 85 grams up to around 400 grams I have soaked them in a NaOH solution for a week and nothing came out so they are very stable. They have a brownish material on the surface but it's not rust, I soaked one in Naval Jelly and it had no effect on it, if it were rust it would have cleaned it up pretty good. I do have a cleaning process that removes most of this weathered material and once I'm done they have a very nice crust. Click this to see a picture of an 85 gram specimen: http://i131.photobucket.com/albums/p298/BobaDebt/Uruacu/85grFragment.jpg There is no oil or anything to make it shiny, it's just the way it looks. If you're interested in a whole specimen send an email off list to bobadebt at ec.rr.com and let me know what your interested in. If you want to include your phone number I will be glad to give you a call to discuss exactly what your looking for.

[meteorite-list] Dust Delays Mars Crater Entry
http://www.jpl.nasa.gov/news/features.cfm?feature=1411 Dust Delays Mars Crater Entry Jet Propulsion Laboratory July 03, 2007 A giant dust storm brewing for more than a week on Mars has become worse and is affecting surface operations of the Mars Exploration Rovers, Spirit and Opportunity. Because the rovers depend on solar energy for survival, and the dust is partially blocking the sun, the storm is being watched closely by the rover scientists and engineers. Opportunity's entry into Victoria Crater is delayed for at least several days. The storm, the most severe storm yet to hit the rovers, is expected to continue for at least another week. Opportunity is perched near Duck Bay as it readies to descend into Victoria Crater, but operations were scaled back on Saturday, June 30, to conserve power. The storm is affecting both rovers and reducing the power levels on Opportunity, said John Callas, Mars Exploration Rover project manager at NASA's Jet Propulsion Laboratory, Pasadena, Calif. We are keeping an eye on this as we go forward, but our entry into Victoria Crater will be delayed until no sooner than July 13. We have some data that show the atmospheric opacity is decreasing, so the storm might have peaked and we may have passed the worst of this. The situation could improve quickly from here, but we will have to wait and see, said Callas. Weather reports from NASA's Mars Reconnaissance Orbiter Mars Color Imager camera are helping track the storm and plan rover operations. Pictures from the orbiter's Mars Color Imager show the storm is regional in extent, and includes several local areas of especially high dust activity. The storm has been moving eastward and toward mid-latitudes, and is now also causing an increase in atmospheric dust at Spirit's location, on the opposite side of the planet at Gusev Crater. Dust levels at Gusev remain much lower than at the Opportunity site, however. Both rovers take daily measurements estimating the amount of dust in the atmosphere. The less dust the better, because it means more sunlight reaches the rover's solar panels, which power the vehicles. In the last week, Opportunity has broken its dust record, with the opacity level rising from 1.0 to 3.3. Solar array energy on Opportunity dropped from 765 watt-hours to 402 watt-hours over the same period of time. While this only represents enough dust to coat the planet to about the thickness of a human hair, it is enough to decrease the brightness of the noon sun by 96 percent compared to a completely clear atmosphere, said Steve Squyres, principal investigator, Cornell University, Ithaca, N.Y. Of course, the solar arrays also receive light that is scattered from the dust, so the decrease in power is not nearly that great. We have not seen dust measurements this high on either rover before. If the dust levels were to increase further and stay elevated for several days, there is a risk to how well Opportunity could continue to work in this darkened environment, said Callas.
