[meteorite-list] India meteorite fall.
Does anyone have the link to the meteorite that fell in India month or so ago? A new one fell near Kendrapara, but I cant find the link someone sent. Mike Farmer __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
RE: [meteorite-list] Advice please; new AZ meteorite classificat ion
Hi Norm, Didn't see any replies to your message about the Arizona meteorite you sent to UCLA for classification, so I thought I'd offer my condolences and advice. > I just checked on the status of the new Arizona meteorite I sent > to Alan Rubin for classification about 6 months ago. He never > received it. Lost in the mail! First order of business would be to confirm the address, but I suspect you've already done so with Alan. Your unfortunate experience is probably the main reason I've hand-couriered my meteorites up to UCLA: time-consuming and much more expensive, but at least I know that they'll get there and get there safely. Obviously this isn't a realistic option for you, so you're stuck depending on the U.S. mail (which is nevertheless probably the best in the world). Even with hand delivery, specimens can get lost or possibly misfiled. (This has only happened once to me out of about hundred meteorites, which is pretty impressive given how many meteorites UCLA classifies a year.) > It breaks my heart to cut off another 25 gm slice to start over > again. Your counsel please. I planned to sell the specimen, > whole or in slices after classification. Should I get it > classified with a further loss of mass, or just sell it right > now, as is??? Tough call, though if it helps a little, you should know that you only need to cut off 20 grams for a proper type specimen. Alternatively, if you choose to sell the remainder whole, you can leave it up to the buyer to get it classified if he/she chooses. It's a nice-looking chondrite, by the way -- congrats on your find! --Rob __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] AD - 71 Great auctions ending soon!
Dear List, Thank you for affording me the opportunity to offer these specimens on a weekly basis. There are several nice specimens being offered this week. Be sure to stay tuned over the next several months as we will be releasing some more fantastic material including a meteorite that took the combined effort of eight laboratories and four years to get classified. We refer to it as the tooth stone because it was like getting a tooth pulled in order to get a classification. We will be introducing several other one-of-a-kinds soon so keep an eye out. In the meantime, check out some of these specimens: 1 gram plus polished slice of NWA032 at 1/4th the price you will find it on dealers' web-sites.

[meteorite-list] Deep Impact Update - August 11, 2005
http://deepimpact.jpl.nasa.gov/mission/update.html Deep Impact Science Team retreat Lucy McFadden August 11, 2005 The Deep Impact science team gathered in Hilo, Hawaii the last week of July for a working retreat to examine the results from Deep Impact's encounter on July 4th. Collaborating astronomers from around the world joined them both in person and via videoconference. The impact of comet Tempel 1 was scheduled to be observable from the ground while the comet was above the horizon in Hawaii, the location of some of the darkest and driest skies in the world. Many of the astronomers who used telescopes at Mauna Kea attended the workshop to learn about the impact from the Deep Impact science team's perspective, which would enable them to better interpret their own data. It was truly a collaborative effort, as the science team is interested in ground-based and space-based results to give us perspective on the Deep Impact spacecraft data. While about 50 people were present at the workshop, we had colleagues attending by videoconference in Germany, and Maryland, USA. We spanned 12 time zones, and didn't know whether to say "Good morning" or "Good Night". We settled on "Aloha" and appreciated our distant colleagues wearing their Hawaiian shirts to feel closer to the pulse of the meeting. Our tasks involved reviewing some of the most interesting data that we collected, reporting on the calibration, checking it and crosschecking, and discussing possible interpretations. We also defined additional questions we need to have answered in order to arrive at robust interpretations of the nature of the comet before impact, the phenomenon of the impact itself, and the effects of the impact afterwards. >From the images posted on the web pages, it is known that the Deep Impact spacecraft returned spectacular data from the collision. Bright dust glowed and illuminated space shortly after impact. The comet zipped by and the spacecraft looked back to see what effects had been made. So much dust was kicked up by the impact, that the science team is still analyzing the images to measure the size of the crater. This analysis continues. The spectrometer showed spectral signatures of water, hydrocarbons, CO and CO2. We continue the analysis of the spectra to determine how hot the water was (between 1000 and 2000 K) and how long it remained hot. The interpretation is a challenge, because the spacecraft and the comet were in motion. That is both an advantage and a challenge. We continue to put together the story of what we saw, when, and how fast the spacecraft was moving. Initial reports from ground-based and space-based observers are varied. Some telescopes saw dramatic changes as a result of the impact, while others did not. One has to recall that the results depend not only on how large a telescope is being used, and its sensitivity, but also at what region of the spectrum the data are acquired. The physics of the impact is not active in all spectral regions. There is a lot of information to be gleaned from both positive and negative results from ground-based and space-based data. Combining those results with that of the Deep Impact spacecraft, that was right there when it happened, but carried only two types of instruments (visible imagers and an IR spectrometer) will provide an interesting scientific story when we get it all sorted out. At week's end we had compiled contributions to a manuscript to be submitted to Science magazine that is scheduled for publication in September 2005. The full set of raw and calibrated data are scheduled to be delivered to the Planetary Data System in January 2006. The Planetary Data System releases the data to the public. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Ambitious Mission Hopes to Return Bits of Asteroid (Hayabusa)
http://www.spaceflightnow.com/news/n0508/22hayabusa/ Ambitious mission hopes to return bits of asteroid BY STEPHEN CLARK SPACEFLIGHT NOW August 22, 2005 Slowly pulling alongside a space rock the size of several typical city blocks, a Japanese probe is preparing to begin scooping the first dusty samples of material from the surface of an asteroid this fall for an eventual return to Earth. Japan's Hayabusa spacecraft is halfway through a four-year $100 million mission to chase down a small celestial target, retrieve pieces of its rocky crust, and return them safely to Earth in a capsule designed to survive the intense heat as it enters the atmosphere and parachutes to a safe landing. Formerly known as MUSES-C, the Hayabusa craft was launched in May 2003 aboard a solid-fueled M-5 rocket to embark on its journey to visit asteroid 1998 SF36. The asteroid, named Itokawa, is in an orbit that brings it close to Earth and is classified as a near-Earth asteroid, meaning its closest approach to the Sun is inside a point 1.3 times further than Earth's orbit. En route to Itokawa, Hayabusa completed one orbit of the Sun and conducted a high-speed flyby of Earth in May 2004, using Earth's gravity to "slingshot" the 1,000-pound probe on an arcing trajectory outward from the Sun to intercept its small target this year. Hayabusa is busy this month calibrating instruments and cameras in advance of its crucial arrival in the vicinity of Itokawa in the middle of September. Its star tracker sighted the asteroid in late July and took a series of 24 images through August 12 to refine the craft's course to the object. Higher resolution imagery will be gathered in the next few weeks using the optical navigation camera. As of August 15, the asteroid had reached magnitude four when viewed from Hayabusa. One of the probe's three reaction wheels responsible for controlling the orientation of the spacecraft failed on July 31 when friction levels went out of limits. Software governing modes of operation for the reaction wheels can support the use of only two of the assemblies, and officials are confident the fix will work. The wheels were built by the Ithaco company based in upstate New York. Operated by the Japanese Aerospace Exploration Agency's space science division, Hayabusa has been propelled chiefly by three ion drive engines relying on xenon gas and electricity to tweak its path toward Itokawa. The high-efficiency propulsion system generates very low levels of thrust, and therefore it must fire nearly continuously for thousands of hours to produce optimal results. A hands-free navigation system is also aboard Hayabusa, demonstrating key technologies that allow the probe to precisely approach Itokawa without intervention or commands from ground teams. During the high-stakes approach, the hybrid system will combine optical and laser data from on-board assets with radio data obtained from ground telescopes on Earth. With the craft now within 6,000 miles of its destination and closing at 82 feet per second, the most critical phase of the mission will soon begin. By Thursday, range will be less than 4,800 miles and the closing rate will be near 50 feet per second. Once it reaches a point around 2,200 miles from the asteroid near the first of September, the ion engines will be turned off to leave Hayabusa coasting toward its target at about 33 feet per second. That closing rate will then be slowed by smaller thrusters using chemical propellants. Although exact dates remain elusive, Hayabusa should come to a relative stop in what officials call the "gate position" a little over 12 miles from Itokawa in mid-September. There it will begin to study the asteroid as it completes one rotation every 12 hours. Hayabusa will not enter orbit, but instead it will remain in a fixed position after the tedious rendezvous sequence. The spacecraft could push onward to the "home position" within five miles of the asteroid's surface before October if all goes as planned. The arrival at Itokawa was delayed two months from earlier this summer after a violent solar flare in 2003 caused damage to the craft's solar array panels that produce electricity, which is needed to power the probe's ion propulsion system needed during the approach. Itokawa is roughly potato-shaped and its dimensions measure about 2,000 feet by 942 feet by 866 feet. It is a member of the Apollo class of near-Earth asteroids that pose potential impact threats to our planet because they often cross paths with Earth during their trip around the Sun. The asteroid travels in an elliptical solar orbit stretching from a furthest point of over 157 million miles to a closest approach to the Sun of around 88 million miles. The asteroid was discovered in September 1998 by a telescope operated by a joint team of U.S. Air Force and MIT scientists under the Lincoln Near-Earth Asteroid Research, or LINEAR, program. >From its static positions five and 12 miles out, the probe will exha

I'm thinking about buying a small collection of "cooler" NWA's but I'm unsure of the current NWA market. I usually stick to the witnessed falls and finds with cool stories, but I thought that this would round out the collection better. Plus they are great under the microscope. Can anyone on the list provide the current retail prices of these NWA's so I can tell if the price that he is asking is OK. Thanks in advance, Derek.
