[meteorite-list] O.T. - Hunting the Harper - Part #2
The following is a continuation from Part 1 of a debris-locating story. (Could have been an asteroid-debris-recovery story had they kept their eyes open for little brown chondrites, but that was to become my story, which will be told later;-) --Bob V. Hunting The ZEL: Part #2 A Tale of Desert Adventure, Crashed Airplanes, and a Search That Would Never End by Curtis Peebles © Copyright 1999 - Harper Dry Lake - The stage upon which the adventure was played out was Harper Dry Lake. The lakebed is about six miles long and three miles wide, and is shaped like an elongated U with the long axis running east to west. At about the midpoint of the lakebed, it is crossed by a dirt road running north to south. Beside it is a barbed-wire fence. The area to the north of the lakebed is a gentle slope, with a surface of sand and small rocks washed down from the surrounding hills. The vegetation is scattered brush. There are a series of flood control channels to the west of the fence, and at the far western end of the lakebed is a solar power station. The only other man-made structures are an abandoned shed, well, and corral The first search attempt I participated in was made on February 22, 1997. Merlin, Moore, and I drove out to the general area. The first problem was to determine the directions of the photos. It was immediately apparent that the shots of the engineers were taken looking almost due east. There were two sets of mountains, and the task became finding a position where the near and far mountains were lined up correctly relative to each other. The photos seemed to show a rolling landscape, with the impact point in a low area, and a rise in the background. In my initial viewing of the tape, I thought I could see a row of cars parked on this rise, indicating a road or hard surface The other two photos were more ambiguous. The shots of the firemen seemed to have been taken looking almost due south, towards several low hills on the horizon. When the two lines of sight crossed, we would find the wreckage. There was not a clear view of the lakebed, but rather two long tan areas against darker areas of brush. This seemed to indicate the impact point was back from the lakebed, with the view of the lakebed blocked by the foreground brush. The overhead shot of the wreckage, however, showed an area almost bare of brush, with a light tan surface and only a scattering of darker rocks. This indicated a site on the edge of the lakebed. The problem was that all we had to work with was photos taken off the television screen Because of the rolling terrain we saw in the photo of the engineers, we started in the general area of the channels, which was west of the fence. We first walked east, than turned back west. I followed Merlin, while Moore went out ahead, closer to the lakebed. This was more than simply a walk in the desert. We were tiny figures alone amid a vast desert. The only sound was our own footsteps on the sandy ground. The landscape extended for miles in every direction, while the horizon beckoned us onwards with the possibility of discovering the object of our quest. Moore was now somewhere out ahead of us, while Merlin's Jeep had become a small white dot behind us in the distance. We finally turned north, then back east, towards the Jeep, and through the flood control channels Every now and then, the surrounding desert seemed to match that in the photos, but each time the feeling faded. At no time did we see any indication that the F-100 had crashed in this area. The ground was undisturbed, and there were no small metal fragments which might have come from an aircraft crash. When Moore came back, he said he had found a clue. He had headed farther west, past the old corral. At one point, he found a set of old truck tracks - so old there were bushes grown in them. The overhead shot had shown a fire truck at the crash site, and was possible that such tracks could remain even after four decades. Moore had found no debris, however. Despite this, the clue looked positive, and we decided to look there on our next attempt - Try, Try Again - The search adjourned for the summer months, and it was not until November 9, 1997 that the second try was made. We went to a part of the lakebed farther west than the area we had searched on the first try. This was the general area where Moore had found the tire tracks. We found a flat area close to the edge of the lakebed which seemed to match the overhead shot. The ground and vegetation was similar, and the surrounding terrain was rolling like that in the shot of the engineers. I felt sure this was the crash site. For more than an hour, I walked back and forth across the area, looking for the telltale glint of metal fragments. But they were not there. This was not the place There was another disappointment awaiting us when we followed the tire tracks. They were as Moore had described them, a single set of dual wheel tracks that we

As I got a good feedback on my last week's superfresh Dho910, I think it might be of interest for some of you, as I listed also some smaller budget specimens. What else do I have? Dho 908, the incredible colourful Moon, always a beauty, all sizes, a thin slice of the honestly spoken most boring looking lunaite on Earth Dho 026 and for the specialists, the number freaks amond the lunatics, the probably last substantial specimen of the small-tkw Dho310. Had only 10.8g. CRW: well 2.5g in Moscow, additonally a thin section was made, no idea if Serge has some material left at all. If yes, he won't give it away at my price. All specimens are listed in dark&cruel German ebay (there you could list a Bob Haag 50gram Ivuna chunk and they would pay 200$ in total, not per gram), so they have startprices. BUT they are lower priced than the finder sells them - thus you won't get it cheaper. At least you could take a look. You can bid via US-ebay, just click in the right top corner "advanced search", choose then "search by seller" and insert my ID: pardelmops Or try this sick long link: http://search.ebay.com/_W0QQsofindtypeZ15QQuseridZpardelmopsQQfclZ3QQsacatZ-1QQsspagenameZhQ3AhQ3AadvsearchQ3AUSQQsofocusZbsQQcatrefZC5QQfromZR7QQpfidZ0QQsinceZ30QQfsopZ1QQfsooZ1QQfrppZ50 Larger slices, endcuts ect. available at better conditions.

[meteorite-list] NPA 11-10-1982 (Wethersfield) Meteorite Crashes through house (again)
Paper: The Gettysburg Times City: Gettysburg, Pennsylvania Date: Wednesday, November 10, 1982 Page: 3 (of 20) Meteorite crashes through house WETHERSFIELD, Conn. (AP) - An object believed to be a meteorite crashed through the roof of a home in this Hartford suburb Monday evening, but occupants of the house escaped injury, police reported. The rock was "slightly bigger than a softball," said police officer Alan Powers, who added that he believed ti was a meteorite. It landed first in the living room of the single family home owned by Robert Donahue on Church Street and then "bounced into the living room," Powers said. Donahue and his wife were home at the time but were in another room watching television when the object smashed through the roof. Powers said his department had received numerous phone calls from residents who reported they had seen "bright lights and then heard an explosion" - phenomena associated with meteors rushing through the atmosphere. The rock was taken to the police station and authorities said they would investigate it further Tuesday to try to determine its origin. Donahue could not be reached for comment by The Associated Press on Monday night; telephone calls to his home went unanswered, and he refused to talk on camera with a Hartford television station. Meteors - some huge fireballs, others tiny specks - bombard Earth's atmosphere at the rate of one million an hour; only about 150 meteors a year survive the trip through the atmosphere and hit the surface of the Earth. Those that make it are called meteorites.

[meteorite-list] NPA 12-22-1982 Smithsonian Returns Wethersfield Meteorite
Paper: Daily Intelligencer City: Doylestown, Pennsylvania Date: Wednesday, December 22, 1982 Page: 27 Smithsonian returns meteorite WETHERSFIELD, Conn. (AP) - The Smithsonian Institution wants to display the meteorite that landed here last month, but the owners of the house hit by the rock aren't sure they want to give it up. "We're trying to arrange with the public library to put it on display," Wanda Donohue. "The people in town should have the opportunity to see it. After that, we're not sure." The meteorite, which scientists say weighed about 50 pounds before hitting the Earth's surface and breaking up on Nov. 8, was recently returned - minus a few fragments - to Mrs. Donahue and her husband, Robert. The black, stony mass has been analyzed at the Battelle Pacific Northwest Laboratory in Richard, Wash., a government-run facility. Chips of the meteorite are undergoing further study at Battelle and in Washington, D.C.; Houston and elsewhere. Roy S. Clarke Jr., curator of meteorites at the Smithsonian's Museum of Natural History, said the meteorite that hit the Donohues' house is similar to the one that landed about a mile away in Wethersfield in 1971. "They are the same, identical class and thus are probably related in space and time." Clarke said. "But how close that relationship is is hard to know." Clarke said both rocks are known as L-6 chondrites, the most common type of meteorite found on Earth. But he said the Donohues' meteorite is important because it is the "freshest" meteorite ever studied. The L-6 chondrites are believed to come from the asteroid belt, a cluster of matter that orbits the sun between Mars and Jupiter. Many scientists believe the asteroids are remnants of an exploded planet.

I wouldn't sell my sample at any price since this is one of the more well researched lunaites from Oman, exhibiting some rather special features such as high-pressure minerals (spinel pyroxenites) suggesting that at least parts of this lunaite formed deep inside the lunar crust (>20kms!!!).

First, it's no impact-melt, regolith, or fragmental breccia, like most other lunaites, but an ultra-rare granulitic breccia. Second, studies by Kuni Nishiizumi have shown it to be one of the most recent lunar falls in our collections, with a terrestrial residence age of less than a few thousand years. Thus, Dho 026, and it's respective pairings are heavily underpriced, if you want my opinion.

[meteorite-list] Wethersfield Meteorite - Part 2 of 4
DENNIS di CICCO (1983) Target Wethersfield - Wethersfield meteorite: The odds were astronomical (Sky & Telescope, 1983 Feb., pp 118-119): Amateur astronomer Phil Dombrowski from the neighboring town of Glastonbury, was among the first astronomically oriented people to talk with the Donahues. He reports that the following took place. After hearing the crash, the Wethersfield couple rushed into the living room and discovered a hole in the ceiling and smoke and plaster dust filling the air. From outside they could see a hole in the roof. Still unaware of what caused the damage and suspecting a fire, they summoned police and fire personnel. About 10 minutes passed between the impact and the discovery of the meteorite under the dining room table, by a fireman who also initially identified its true nature. The stone, weighing just over 2.7 kilograms (almost six pounds), came through the roof and ceiling with such force that before coming to rest it bounced off a carpeted wooden floor; hit the dining room ceiling, dislodging more plaster; struck and overturned a small chair; and dented a wall. News traveled quickly, and by the next morning local newspapers and radio stations were carrying the story. Residents of Wethersfield, who recalled that a meteorite crashed through the roof of a house less than two miles from the Donahue home on April 8, 1971 (see this magazine for June, 1971, page 346), found the 1982 event quite plausible. Some scientists, however, were less inclined to accept immediately the remarkable coincidence. Roy Clarke of the Smithsonian Institution in Washington, D.C., flew to Connecticut the day after the fall occurred and arranged to borrow the meteorite so that it could be properly analyzed. Although several chips, which broke off the main body on impact, were given to the Smithsonian and local colleges for study, the Donahues requested that the large meteorite not be further damaged. (As of mid-December they had not decided what they would ultimately do with it.) __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Wethersfield Meteorite - Part 3 of 4
DENNIS di CICCO (1983) Target Wethersfield - Wethersfield meteorite: The odds were astronomical (Sky & Telescope, 1983 Feb., pp 118-119): A preliminary examination made at the Smithsonian revealed that the stone was an L6 chondrite (the most common type of meteorite found on Earth). Furthermore, it is almost identical in type to the one that hit Wethersfield in 1971. The main difference between them is that the earlier object showed more signs of having withstood violent shock due to preterrestrial impacting. The stone was shipped to John Evans of Battelle's Pacific Northwest Laboratories in Richland, Washington, where it was studied for the effects of cosmic-ray exposure while in space. In this way the meteorite was used as a probe to determine how cosmic-ray intensity within the solar system varies with time. As an aside, Evans notes that the radioisotope cobalt-60 was below detectable levels in the stone. From this he deduced that it was probably not part of a considerably larger body when it hit the Earth's atmosphere. The fireball associated with the meteorite's passage through the air was widely observed across New England, New York, and New Jersey. David Menke of the Central Connecticut State College (CCSC) Copernican Observatory collected eyewitness reports. In the days following the event he fielded hundreds of telephone calls from persons who saw the fireball. According to Menke, most observers claim that the object broke into three or more pieces during its flight. This gave rise to the speculation that more fragments might be located around Wethersfield. Also, the thin fusion crust suggests that the meteorite is part of a larger body that broke up in the atmosphere. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Wethersfield Meteorite - Part 4 of 4
DENNIS di CICCO (1983) Target Wethersfield - Wethersfield meteorite: The odds were astronomical (Sky & Telescope, 1983 Feb., pp 118-119): Dombrowski contacted several people who saw the fireball. He reports that Ted Pace, a former seafaring navigation officer from Mahwah, New Jersey, saw the meteor plunge almost straight down in the eastnortheast part of the sky. Through a window in his home at Marlborough, Massachusetts, Robert De Collibus viewed about three seconds of the meteor's flight. It appeared in the southwestern sky. Stan Hedden of Glastonbury, Connecticut, was out jogging about five miles from the meteorite's impact site when the entire sky appeared to light up. He looked up to see the fireball about 5° northwest of the zenith. It never appeared to move during his observation since it was flying almost directly at him! Between 30 and 50 seconds after he saw the fireball, Hedden heard what sounded like gunshots coming from the direction of Wethersfield. These and other reports, along with the orientation of the hole in the Donahue's roof, give a good indication of the meteorite's direction of travel. Menke and Charles Hammond, also of CCSC, believe the object approached from 25° off the vertical at an azimuth of 295° (west-northwest). It probably passed over Canaan, Connecticut, in the northwest part of the state, on its way to Wethersfield. Certainly one of the most outstanding aspects of the 1982 Wethersfield fall is the almost incalculable odds that two separate meteorites could strike houses in the same town. There are, however, several other cases of meteorites falling very close to one another. According to Ursula Marvin of the Harvard-Smithsonian Center for Astrophysics, a stony meteorite was found near the rim of Arizona's Meteor Crater, which is known to have been formed by an iron meteorite. Also, in Ontario, Canada, the Sudbury structure is believed by many to be an ancient meteorite impact feature. A much younger crater is superimposed on it. Thus, not only were there two falls in the same location, but they were large enough to leave enduring impact craters. What makes the pair of Wethersfield falls so special is how closely they are spaced in time. Only 11 years elapsed between the two whereas the earlier events were separated by thousands or even millions of years.

[meteorite-list] Formaldehyde Claim Inflames Martian Life Debate
http://www.nature.com/news/2005/050221/full/050221-15.html Formaldehyde claim inflames martian debate Mark Peplow nature.com February 25, 2005 Top scientist defends data that he says point strongly to life on Mars. Formaldehyde has been found in the martian atmosphere, according to a senior scientist working with the Mars Express orbiter. If correct, the discovery provides strong evidence that Mars is either extremely geologically active, or harbouring colonies of microbial life. But many experts are not yet convinced. The claim comes from Vittorio Formisano, who is in charge of the Planetary Fourier Spectrometer on the European Space Agency's orbiter. The spectrometer analyses infrared light, whose frequencies carry the fingerprints of chemicals in the atmosphere. The most likely source of formaldehyde (CH2O) is the oxidation of methane (CH4), which has already been identified in the martian skies. So the presence of formaldehyde itself is not too surprising, says Michael Mumma, of NASA's Goddard Space Flight Centre near Washington DC, who studies the martian atmosphere. Any oxidizing atmosphere such as Mars's that contains methane should also have formaldehyde, he explains. Big claim The truly eye-opening part is the sheer quantity of formaldehyde that Formisano claims to have found: about 10 to 20 times more than there is of methane. This means that estimates of martian methane production must be revised upwards substantially, as most of the gas is oxidized as soon as it comes out of the ground, he says. "If you consider formaldehyde as oxidized methane, then Mars is producing 2.5 million tonnes of methane a year," says Formisano. This is simply too much to be accounted for by any known geological process, he says, so some other source (possibly life) must be involved. However, other planetary scientists say the planet alone could still be responsible. "We don't know the intricacies of [martian] geochemistry," says Rocco Mancinelli, an astrobiologist from NASA's Ames Research Center in Moffett Field, California. Formisano presented his results to a packed session of the Mars Express Science Conference at Noordwijk in the Netherlands on 24 February. Unstable hope The discovery of martian methane last year excited scientists, who said that there were two likely sources of the gas: active geological processes beneath the planet's surface or a population of methane-generating microbes. Because Mars was long thought to be a dead planet, devoid of both life and geothermal activity, either prospect came as a revelation. However, a molecule of methane can typically survive for about 350 years in the atmosphere before being broken down by the Sun's ultraviolet radiation. So the possibility remained that the gas could have been delivered to the planet by a colliding comet, or by an occasional release from an underground reservoir. Formaldehyde is far more unstable, surviving for just 7.5 hours or so before breaking apart. The majority of scientists agree that methane is the most likely precursor for formaldehyde on Mars, so this means that the planet's production of methane must be an ongoing, continuous process, says Formisano. Going sceptic Formisano is careful to point out that he has not proved there is life on Mars. "I do believe there is life inside the planet, maybe 50 to 100 metres below the surface, but there is a long way to go to demonstrate that." "We all want to believe in something," says Yuk Yung, a planetary geologist from the California Institute of Technology, Pasadena. "Even as scientists we're not completely objective, especially about something we've worked on for ten years. There's enormous pressure to deliver, and under this pressure you can easily believe things that are unbelievable." Many scientists are sceptical about the quality of Formisano's data. "The measurements are right on the borderline of the [instrument's ability]," says Mancinelli. "I don't believe it," adds Yung. He explains that Formisano's infrared fingerprint of the formaldehyde in Mars's skies should match a laboratory sample of the gas, "and the match is just not convincing". But Formisano argues that his martian spectrum tallies in 15 key places, which should be enough to convince anyone: "It's not a matter of opinion any more," he says. He adds that, since he presented his data at the conference, several sceptics have already changed their views. He points out that although rejected by Nature, the research will soon be published in the journal Planetary and Space Science. Acid test Formisano also announced at the conference that he has found traces of hydrogen fluoride (HF) and hydrogen bromide (HBr) in the atmosphere, which are probably produced when acids break down certain minerals in the soil. Many scientists believe that Mars once had briny, acidic seas that may have been conducive to life. "An acidic environment still exists," says Formisano. "On Earth, there are certain bacteria th

[meteorite-list] Quarter of Mars Scientists at European Meeting Believe Life Possible on Mars
http://space.com/scienceastronomy/mars_believe_050225.html Quarter of Mars Scientists at European Meeting Believe Life Possible on Red Planet By Peter B. de Selding Space News 25 February 2005 PARIS - Three-quarters of the 250 Mars science experts meeting to analyze the results from U.S. and European Mars probes believe life could have existed on Mars in the past, and 25 percent think life could be there even now, according to a poll released Feb. 25. The poll was announced during a press briefing following the First Mars Express Conference, held Feb. 21-25 at the European Space Agency's Estec technology center in Noordwijk, Netherlands. The results perhaps reflect the sober caution of scientists who refuse to jump to conclusions before conclusive evidence is in about the No. 1 issue on the minds of everyone attending the conference, held to review a year's operations of Europe's Mars Express orbiter. Everett K. Gibson of NASA's Johnson Space Center in Houston, who attended the meeting as a Mars interdisciplinary scientist reviewing the results of all the Mars experiments, said the available data lends credence - but as yet offers no proof - to the idea that the methane and formaldehyde present in Mars' atmosphere is evidence of underground life. Gibson said definitive proof likely will require a future Mars mission carrying sophisticated drills to penetrate beneath the Mars surface to take samples directly or - a preferred option - to return them to Earth for laboratory evaluation. "Mars is revealing her secrets, but slowly," Gibson said. "We need those samples or in-situ measurements." In a series of presentations on each of Mars Express' seven experiments, several scientists stopped just short of saying that the evidence so far points to life buried under the surface of Mars away from the ravages of the solar wind. One possible explanation for the absence of liquid water on the surface of the planet is that Mars, which unlike Earth does not have a protective magnetic field, is being shorn of its surface by the solar wind. An estimated 100,000 kilograms per day of Mars surface material is blown off the planet, according to Stas Barabash, lead scientists for the Mars Express ASPERA-3 experiment, which measures the phenomenon. Vittorio Formisano, lead scientist for the Mars Express Planetary Fourier Spectrometer, which is investigating Mars' atmosphere, said the differing levels of concentration of methane and formaldehyde are cause for optimism that life exists under the surface. "We need more work for a final conclusion," Formisano said, adding: "Life is probably the only source that could produce so much methane. The question is not any more, Was there life on Mars? The question is: Is there life on Mars today?" __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] tile saw cut meteorites?
I have tried tile saws with some success. Unfortunately the cutting loss is great. Also tile saws do not leave smooth cuts because the slice needs to be hand feed through the saw. After the cut you really need to sand the cut face with various grits of paper until you have an acceptable smooth face. Using a tile saw is only good for cheaper, and soft, NWA stones. Still lots of fun though.

Re: [meteorite-list] tile saw cut meteorites?
Hey, I like to use the wide blades, they cut faster and don't flex when the specimen is twisted by accident. There is less meteorite surface that needs to be smoothed off when you are done cutting if you use the bigger thicker blade. A vice like a work mate, and a good hand grinder makes initial smoothing go much faster. A good old fashioned bench grinder takes off the saw cuts pretty fast too, saves a lot of time spent standing over your specimen wondering what to take off and what not to take off.. Plenty of 80 grit sanding wheels get the task of initial smoothing done right with the program. When you are all done you can use a good wet/dry shop vac to clean up your mess and save those nice pieces of coarsely ground meteoritte for later, and put in a pie!

Re: [meteorite-list] tile saw cut meteorites?
Tom, My advice is to get a regular lapidary saw the largest size that you can afford. If you get a 6 inch you may be kicking yourself for not being able to slice up a large stone. After some practice your cuts will be smoother and you will have half the cut loss that you would have with a tile saw.Getting one with a clamp is a definite plus. Don't worry about cutting with water. I cut with water all of the time. Its alot cleaner than cutting with oil. Just put the meteorites in a toaster oven for 15 minutes right after you cut them. They shouldnt rust.

Rod saws, wire saws, are great for cutting thin ceramic tile, usually soft wall tile. It would be a waste of time and a good meteorite to try and use them in this way. Imagine trying to cut a meteorite with a hack saw but with less control.

Re: [meteorite-list] tile saw cut meteorites?
The few kilos of Estherville I received had 1/4" wide cuts in them, probably from a cut-off saw or grinder. Cut loss did not seem to be a factor back then, several years ago, by non-collectors, or some geologists.
