Re: [meteorite-list] Telescope experts
Hi. Never buy a reflector telescope under 115mm diameter, and in case of refractors under 70mm, they won't worth anything under this measures, it's the same as throwing your money. Some good eyepieces are fundamental too; those chinese telescopes on ebay could do the job... but just if you at least change the eyepieces, and they are no cheap, so it's better to buy another telescope that includes some good ones.

Re: [meteorite-list] Breja Stone, chondrite
Thanks to everybody for your interest and your kind comments on the photo of the Taousz/Breja stone which Michael kindly posted. Much appreciated. Carl, the degree of brown vs black in the color of the fusion crust of a freshly fallen chondrite is a function mainly of the magnetite (FeO·Fe2O3) content in the crust. The oxide composition in turn is basically controlled by the supply of oxygen during the formation of the crust. Thus, trailing faces, which formed in near vacuum, often show a rich brown instead of the common dull black. A textbook example is the little oriented Buzzard Coulee pictured here: http://www.meteorite-recon.com/en/Meteorite_fusion_crust_2.htm Cheers Svend http://www.rocksfromspace.org/taousz.html cdtuc...@cox.net hat am 6.

Re: [meteorite-list] Wanted: Meteorites from Mercury
Sterling makes some good points. The other thing besides trapped atmospheric gases that make the SNC's planetary is their relatively young igneous crystallization ages (except for ALH84001) -- indicating geologically long-lived volcanism on a large parent body. All angrites have ancient crystallization ages, in fact SAH99555 has perhaps the oldest crystallization age of any igneous rock in the known solar system. It is assumed that a body of Mercurian size would have at least a billion years of igneous activity and probably longer (like the Moon). If so it might take several 10's of millions of years to form a permanent crust from which to derive meteorites. Hence the zero age of angrites do not fit this picture well, more likely a smaller body, but not definitive. On the other hand, neither do the aubrites. As much as I would like our low-FeO 1-ton Norton County aubrite to be a Mercurian meteorite, this also seems unlikely because of it ancient age ~4.55 BY. The color argument is a tricky one because we have no idea what causes the Mercurian regolith to be darker than say an aubrite, and this is because of the intense stream of solar wind on rock surfaces which may have a huge on surface coloration. Another thing to remember is that none of the orbiters at Mars have ever spotted a terrain on the martian that is exactly the same as SNC meteorites, so based just on orbital data you would never know SNCs are from Mars -- dust coating is a big problem. There probably isn't as much dust on Mercury, but keep in mind that the interpretation of spectral data from orbit is as much art as it is science and ground-truth calibrations are hard to come by, so knowing the Sun's interaction with the Mercurian regolith maybe just as problematic. This is definitely a work in progress! Of course a NASA sample return mission would be my recommendation! I'm not picky, Mercury, Venus, Mars...

No, not rock samples, nor any returned samples, but the isotopic composition of rare gases in the Martian atmosphere, which made a distinctive and unusual signature (particularly for Argon). The SNC's shared this unique signature. It was like a fingerprint. And possible only because we had a lander on the surface.. Mercury has no atmosphere of any consequence and we have no lander there.

Re: [meteorite-list] Telescope experts
Hi, Pete, All astronomy magazines have regular articles on good telescope purchases for the whole range of price. Personally, I don't recall ever seeing one recommended for under ~$200.00. They will also advise that for a noob, it is best to start with a good pair of binoculars. Personally, I have a less expensive decent telescope, which wasn't cheap, and which rarely gets used since I spent only $70.00 CND on Celestron 15 x 70 binoculars (on sale every summer in Canada - Canadian Tire, for my fellow Canucks), and I'm completely content with them. They have extra-wide field oculars with rubber cups (great, if you need glasses), come with a tripod adapter so you can use it with your camera 'pod, and it goes without saying the versatility. Telescopes are definitely something you should graduate into, not start from.

Re: [meteorite-list] What's going on in the background?
What's going on in the background? Hola Martin, Comes meteoritae; It would seem Sigismondo d' Conti (1432 -1512) commissioned this 1511 painting to commemorate how he narrowly escaped death by a fragmenting cannonball during the 1439 seige of Foligno, by the Status Pontificius who were retook his city after Corrado IV Trinci withdrew it from the Pope's tributary possessions. Conti attributed his survival to his guardian angel. He would have been about 7 years old during the seige, and was probably in a process of atonement and praise God, since he would die with a year after the painting was finished. Foligno is in the background under a rainbow, or halo, probably to show the presence of the angel (the left arch in your partial image of the painting). The projectile is represented on the right. Alternately, in Abraham Kaplan's word's I call it the law of the instrument, and it may be formulated as follows: Give a small boy a hammer, and he will find that everything he encounters needs pounding. It comes as no particular surprise to discover that a scientist formulates problems in a way which requires for their solution just those techniques in which he himself is especially skilled. Of course Mr. Kaplan didn't imagine what we would imagine a hammer could be ;-) Kindest wishes Doug -Original Message- From: Martin Altmann altm...@meteorite-martin.de To: meteorite-list meteorite-list@meteoritecentral.com Sent: Mon, Jan 9, 2012 9:36 am Subject: [meteorite-list] What's going on in the background?

[meteorite-list] Mirror Casting Event for the Giant Magellan Telescope
FOR IMMEDIATE RELEASE FROM THE UNIVERSITY OF ARIZONA Jan. 9, 2012 Contact information follows this news release. Mirror Casting Event for the Giant Magellan Telescope On Jan. 14, the second 8.4-meter (27.6 ft) diameter mirror for the Giant Magellan Telescope, or GMT, will be cast inside a rotating furnace at the University of Arizona's Steward Observatory Mirror Lab underneath the campus football stadium. The mirror lab will host a special event to highlight this milestone in the creation of the optics for the Giant Magellan Telescope. Members of the media are invited to visit the mirror lab on Jan. 14 between 9-11 a.m. MST to see the liquid glass as it is spun cast in a rotating oven at a temperature of 1170 degrees C (2140 F). This casting marks another major step in the construction of the Giant Magellan Telescope. There will be opportunities to interview leading scientists and engineers involved in the project. The GMT features an innovative design utilizing seven mirrors, each 8.4 meters in diameter, arranged as segments of a single mirror 24.5 meters (80 feet) in diameter, to bring starlight to a common focus via a set of adaptive secondary mirrors configured in a similar seven-fold pattern. In this design the outer six mirrors are off-axis paraboloids and represent the greatest optics challenge ever undertaken in astronomical optics by a large factor, said Roger Angel, director of the Steward Observatory Mirror Lab, or SOML. The GMT will allow astronomers to answer some of the most pressing questions about the cosmos including the detection, imaging and characterization of planets orbiting other stars, the nature of dark matter and dark energy, the physics of black holes, and how stars and galaxies evolved during the earliest phases of the universe. The GMT will allow astronomers to observe for the first time the first stars formed after the Big Bang, said Steve Finkelstein, Hubble Fellow at The University of Texas at Austin. I cannot wait to make these observations. Astronomical discovery has always been paced by the power of available telescopes and imaging technology, said Peter Strittmatter, director of Steward Observatory. The GMT allows another major step forward in both sensitivity and image sharpness. In fact the GMT will be able to acquire images 10 times sharper than the Hubble Space Telescope and will provide a powerful complement not only to NASA's 6.5-meter James Webb Space Telescope, or JWST, but also to the Atacama Large Millimeter Array, or ALMA, and the Large Synoptic Survey Telescope, or LSST, both located in the southern hemisphere. Patrick McCarthy, GMT project director, added, This second GMT casting is going forward now because the primary optics are on the critical path for the project, and because the polishing of the first off-axis 8.4-meter GMT mirror is very close to completion, with an optical surface accuracy within about 25 nanometers, or about one-thousandth the thickness of a human hair. Like other mirrors produced by the SOML, the GMT mirrors are designed to be spun cast, thereby achieving the basic front surface in the shape of a paraboloid. A paraboloid is the shape taken on by water in a bucket when the bucket is spun around its axis; the water rises up the walls of the bucket while a depression forms in the center. Some 21 tons of borosilicate glass, made by the Ohara Corporation, flow into a pre-assembled mold to create a lightweight honeycomb glass structure that is very stiff and quickly adjusts to changes in nighttime air temperature, each resulting in sharper images. The mirror lab has already produced the world's four largest astronomical mirrors, each 8.4 meters in diameter. Two are in operation in the Large Binocular Telescope, or LBT - currently the largest telescope in the world; one is for the LSST, and the fourth is the first off-axis mirror for GMT. The UA's Mirror Lab has also produced five 6.5-meter mirrors, two of which are in the twin Magellan telescopes at Las Campanas Observatory in Chile. The novel technology developed at the mirror lab is creating a whole new generation of large telescopes with unsurpassed image sharpness and light collecting power, said Wendy Freedman, director of the Carnegie Observatories and chair of the GMTO Board. The SOML mirrors in the twin Magellan Telescopes at our Las Campanas Observatory site are performing superbly and led to our adoption of this technology for the GMT. The GMT is set to begin science operations in 2020 at the Las Campanas Observatory, exploiting the clear dark skies of the Atacama Desert in northern Chile. With funding commitments in hand for close to half of the $700 million required to complete the project, with one mirror essentially finished and the second about to be cast, and with the planned groundbreaking at Las Campanas in February of this year, the project is on track to meet this schedule goal, said Matthew Colless, Director of the Australian Astronomical

[meteorite-list] China Targets 2013 For Launch of Lunar Landing Mission
http://www.spaceflightnow.com/news/n1201/09chinamoon/ China targets 2013 for launch of lunar landing mission BY STEPHEN CLARK SPACEFLIGHT NOW January 9, 2012 Under a new five-year plan unveiled in December, China will continue to make methodical progress in human spaceflight, expand its satellite navigation system, explore the moon and seek space technology partnerships with developing nations. China also plans to test new rocket systems to haul hefty payloads into Earth orbit with kerosene fuel, a less toxic alternative to hydrazine used on today's Chinese Long March boosters. China is constructing a new spaceport on Hainan Island off the southern coast of the country's mainland. The fresh five-year plan will kick off in 2012 with the launch of two Shenzhou spaceships to dock with Tiangong 1, a prototype space station module launched in September 2011. An unmanned Shenzhou capsule accomplished China's first robotic docking in orbit in November. At least one of the Shenzhou missions this year will carry a crew of astronauts. Chinese officials have not disclosed a timetable for either mission, which are named Shenzhou 9 and Shenzhou 10. In the next five years, China will launch space laboratories, manned spaceships and space freighters, the plan says. The country will also make breakthroughs in and master space station key technologies, including astronauts' medium-term stay, regenerative life support and propellant refueling. China plans to make technological preparations for the construction of a 100-ton space station and initiate research to land humans on the surface of the moon. Engineers are developing the Chang'e 3 robotic lunar lander for launch in 2013, the second phase of a three-step moon exploration effort. China successfully sent two Chang'e orbiters to the moon in 2007 and 2010, collecting sharp imagery for a high-resolution map of the lunar surface. Controllers dispatched Chang'e 2 from lunar orbit to a position at the L2 libration point a million miles from Earth, the furthest distance any Chinese probe has ever traveled from Earth. The third step in the robotic lunar program is to return samples to Earth. China is also prioritizing Earth observation, communications and navigation satellites. Nigeria, Venezuela and Pakistan purchased government-owned broadcasting satellites for launch by Chinese rockets, and further craft are under construction in China for Bolivia, Laos and Belarus. China says it will continue negotiating satellite and launch agreements with developing countries. Another focus for Chinese space officials will be the continued deployment of the Beidou navigation system, a satellite network designed to provide positioning services independent of the U.S. Air Force's GPS program. China activated the Beidou system Dec. 27 on a trial basis. Its 10 satellites currently provide services over the Asia-Pacific region, including most of China. The coverage zone stretches from the southern border of Russia to Australia, and from India in the west to the Pacific Ocean in the east. Global coverage will be possible by 2020 with a constellation of 35 satellites, according to the state-run Xinhua news agency. __ HAPPY HOLIDAYS!!

The most common Dob _is_ an 8-inch reflector.

Re: [meteorite-list] telescope
On a limited budget, a small refractor is best for casual planetary and lunar viewing. Small reflectors are more suited for viewing deep space objects, such as galaxies and nebulas. Avoid reflectors under 100mm in aperture. Their large central obstruction from the secondary mirror blocks out too much light. You'd get a better, brighter, sharper image through a 60mm refractor than through a 80mm reflector. I started out in astronomy decades ago with a quality 60mm tabletop spotting scope with a zoom eyepiece. I could easily see all 4 of Jupiters' moons, the rings of Saturn, the orange disk of Mars, the phases of Venus, 7 stars of Pleiades, and Orion's nebula with it. Ignore all the magnification power hype. A useful magnification guideline is 50-60x per inch of aperture. So 60mm(2.4 inches) will yield a maximum useful magnification of about 140x. More than enough for the casual astronomer. Beyond that magnification and everything begins to look crappy, dark and fuzzy. Remember, even on a low budget, you can still find a good quality scope. Look for a coated(multi-coated if you're lucky) air-spaced achromatic lens and good multi-element .965 or 1.25 sized eyepieces. A finderscope is a non-essential accessory and usually useless junk anyways. __ HAPPY HOLIDAYS!!

Re: [meteorite-list] Wanted: Meteorites from Mercury
Carl, You make a very convincing argument against your Norton County Aubrite being from Mercury. Especially when you do consider it's very low Iron content and it's white color. I have seen many Aubrites and I do not ever recall seeing one with zero observable iron. But, What do you think about Mayo Belwa being mis-classified? It not only looks way different than most of the other Aubrites in that it has a lot of darker colored material but, it also has no visible metal at all (at least from photos I have seen). Including red rust spots. It was also studied by non- American scientists that may or may not have tested it for it's true age? So, maybe it is young enough to be a Mercurian candidate? Or maybe it is old but, still from Mercury? Could it be mis-classified? I mean it happens. Look at ALH84001. As a trained architect; I see a relationship between Art and Science and on the art side ( visible) Mayo Belwa looks much different than the other 62 known Aubrites. And on the Science side; Lets just say that I'd like to see more science done by Americans. Surely it has a lower total iron content than even Norton County has and according to the Messenger, Mercury also has extremely low iron (maybe none). Maybe the detected iron is exclusively from meteorite hits? Carl meteoritemax -- Cheers Carl Agee a...@unm.edu wrote: Sterling makes some good points. The other thing besides trapped atmospheric gases that make the SNC's planetary is their relatively young igneous crystallization ages (except for ALH84001) -- indicating geologically long-lived volcanism on a large parent body. All angrites have ancient crystallization ages, in fact SAH99555 has perhaps the oldest crystallization age of any igneous rock in the known solar system. It is assumed that a body of Mercurian size would have at least a billion years of igneous activity and probably longer (like the Moon). If so it might take several 10's of millions of years to form a permanent crust from which to derive meteorites. Hence the zero age of angrites do not fit this picture well, more likely a smaller body, but not definitive. On the other hand, neither do the aubrites. As much as I would like our low-FeO 1-ton Norton County aubrite to be a Mercurian meteorite, this also seems unlikely because of it ancient age ~4.55 BY. The color argument is a tricky one because we have no idea what causes the Mercurian regolith to be darker than say an aubrite, and this is because of the intense stream of solar wind on rock surfaces which may have a huge on surface coloration. Another thing to remember is that none of the orbiters at Mars have ever spotted a terrain on the martian that is exactly the same as SNC meteorites, so based just on orbital data you would never know SNCs are from Mars -- dust coating is a big problem. There probably isn't as much dust on Mercury, but keep in mind that the interpretation of spectral data from orbit is as much art as it is science and ground-truth calibrations are hard to come by, so knowing the Sun's interaction with the Mercurian regolith maybe just as problematic. This is definitely a work in progress! Of course a NASA sample return mission would be my recommendation! I'm not picky, Mercury, Venus, Mars...

No, not rock samples, nor any returned samples, but the isotopic composition of rare gases in the Martian atmosphere, which made a distinctive and unusual signature (particularly for Argon). The SNC's shared this unique signature. It was like a fingerprint. And possible only because we had a lander on the surface.. Mercury has no atmosphere of any consequence and we have no lander there. It's always possible that our present sensing capacity will turn up something as definite, but I can't think of what it could be. Believe me, I've tried. Sterling K. Webb -- Carl B.

[meteorite-list] 2nd Annual Eating Around Tucson - 2012
Hey, List Members! I have it on good authority that Tucson is fast approaching! With that in mind, I am once again giving my “Annual Eating Around Tucson” list. This list has been put together with over twenty years of attending the shows. These are my opinions (well, my wife, Cookie, too!) only. I have no vested interest in any of these establishments, no free food, etc! I just like good food! Maybe you will find my/our tastes different from yours but all of these are worth a try! I’m leaving for Tucson Friday of this week! This spring, I was finally able to retire from my ‘real’ job of teaching! One item on my ‘bucket list’ was to drive (rather than fly, which I have done for 15-20 years!) and enjoy more of Arizona. We have side trips planned to Meteor Crater, Bisbee, etc. And, I will get to attend the MAIN show for my first time (about time, huh?)! My wonderful wife is still working and will not be able to fly out until the end of the month. I hope to get some food scouting done before she arrives and have some new places for her to visit! I am adding some new locations suggested by list members last year after my initial post. I did get to try some of them and enjoyed them VERY much. I hope to add more this year! * Pat's Drive In, 1202 West Niagara Street, 520-624-0891 I should not list this first, but I AM! I first read about Pat's in Arizona Highways magazine. It is a tradition in Arizona! It is on a side street off N. Grande Ave, between Speedway and St. Marys. It is near the condo that we rent each year. I had driven within half a block of it for years and did not know it existed! If you like the old drive in restaurants, this IS the place for you! If you like greasy fries by the pound, this is for you! If you like GREAT chili hotdogs, this IS the place for you, please note that they have three degrees of heat for their chili! We have three favorites that we think everyone should try at least once. In no particular order: * La Fuente Restaurant, 1749 N. Oracle Rd., 520-623-8659 REALLY good Mexican/Tex-Mex food. The lunch buffet is very good and very reasonable. If you're there for dinner, be sure to order the Guacamole made table-side. It is VERY GOOD! * Silver Saddle Steak House, 6th Ave. I-10 (310 E. Benson Highway), 520-622-6253 This place is near downtown and has some of the best steak that I've had in Tucson. If you're going for dinner, it is best to get there early or be prepared to wait 30 minutes to an hour. It IS worth the wait! I do not think that they take reservations. * Lil Abner's Steakhouse, 8501 N Silverbell Rd., 520-744-2800 This is a MUST for Tucson show visitors. I remember going there a lot of years ago when this place was truly in the middle of nowhere! If you go this year, you'll she how that has changed. It use to be a drive out into the desert! Any of the show weekends will have tons of show folks there! The steaks rival Silver Saddle but everything is served with a salad, beans, and bread! LOVE the atmosphere there! * Daisy Mae's Steak House, 2735 W. Anklam Rd., 520-792-. This is just down the street from the condo we rent while in Tucson. Great steaks! Other recommendations: Breakfast recommendations: * Blue Willow, 2616 N. Campbell Ave. Tucson, AZ 520-327-7577 If you want to take time for a nice, leisurely breakfast, this is THE place! Food is great, prices are reasonable. It is in a house converted to a restaurant. * Los Betos Mexican Food, 914 E Speedway Blvd, 520-884-5291 and 32 N Campbell Ave 520-628-7462 plus several other around town. If you're looking for something that will keep you going through MOST of a day visiting shows without having to stop to eat lunch, try the burritos at any Los Betos! There are many breakfast burritos available and VERY reasonably priced. Last year the one on Speedway was closed for remodeling. I hope it has reopened as it is so convenient to several of the shows. Look for a Los Betos! Fun evening choice: * Chuy's Baja Broiler, 3100 E Speedway Blvd, 520-326-4969 plus several other around town! Good food, GREAT chip and salsa bar, but if you go, you MUST the pitcher of Margaritas! Don't order a pitcher just for yourself IF you are driving! 'Nuff said! * Country Folks Restaurant, 1015 East Benson Highway, 520-622-8844 This is right next door to Marty Zinn's show at the Quality Inn on Benson Hwy. They have a very reasonable priced buffet for all three meals! Good food and plenty of it. We usually try to schedule a couple of days around Country Folks for breakfast or lunch! Really nice folks! I must say that sometimes the buffet is not up to par after the regular breakfast or lunch times. Other times it is GREAT! And you can walk next door to or from the show! Tradition choices: El Charro Cafe, Bar Toma! Gift Shop, 311 N. Court Ave., 622-1922 This place has been in business since 1922 in Tucson! That says it

Re: [meteorite-list] Display Hardware and Suggestions Needed.
I've always favoured the caliper display over all others, Alex. The nicer ones give that orrery feeling to them, making it a natural for a meteorite display! I've got some 9 brass rings set aside. I thought I'd try to make a model atom with the rings representing the electron orbits, and a choice meteorite as the nucleus.
