Re: [meteorite-list] Mercury Fragments on earth (not)
Perhaps, Sterling, you are saying we should keep an open mind. I don't totally disagree, but There are some things that can help distinguish a meteorite from other rocks, no matter where it comes from. Number one: It will have or had a fusion crust. If you take the number of Martian meteorites found with at least some fusion crust, then according to the authors calculations there should be 1/2 to 1/3 as many Mercurian meteorites found also with fusion crust. If so, they should already have a class established like SNC, even if we don't know where they are from. Keep in mind that we thought the SNC meteorites were in some way special, long before we were certain they were from Mars. Were you saying a Mercurian meteorite won't be recognized as a meteorite or just that we won't be able to tell if is from Mercury? Mike Fowler PS At the time when we could have said there are no lunar meteorites, the total number of meteorites known was about 7,000 compared to todays totals of maybe 100,000 and growing! When a science is in its infancy, obviously there are many things yet to discover. There was a time when you could say: The fact that Lunar meteorites have not been found on Earth is prima facie evidence that there are none. There was a time when you could say: The fact that Martian meteorites have not been found on Earth is prima facie evidence that there are none. Humans have stared at both and had no idea of what they were looking at. Martians were frequent enough to get and maintain a class all their own for centuries before we knew, and Lunars we probably just tossed over our shoulders without a thought. I say: This is a time when you (or I) can say: The fact that Mercurian meteorites have not been found on Earth is prima facie evidence that we can't recognize them! We don't know what they are. We are probably quite wrong about what to expect. Sterlng K.

Interesting to note: I've just re-re-read Robert T. Dodd's METEORITES, A Petrologic-Chemical-Synthesis published 1981...and as early as the Introduction (page 9) the concept of lunar meteorites was at that time completely ruled out: Although returned samples confirmed that the lunar maria consist of basaltic rocks, lunar basalts differ sufficiently from analogous achondrites in composition and age to rule out a common sourse (Section 8.1), and other lunar rocks are completely different from known meteorites. Some meteoritic material is present in the lunar regolith, but the converse is not true: There seems to be no lunar component in terrestrial meteorite collections. WOW! As recently as only 30 years ago, with advanced analysis, meteoritic specimens were un-notoiced.

Re: [meteorite-list] Mercury Fragments on earth (not)
Richard, List, The timing is perfect. 1981? It was January 1982 when John Schutt found an odd Antarctic meteorite, Allan Hills 81005. At the Smithsonian, Brian Mason thought it resembled some rocks brought back from the Moon by Apollo, and it was recognized. A few years later, Yamato 791197, found in 1979 in Antarctica was recognized as a Lunar, so when Dodd wrote that in 1981, there was already a collected, catalogued Lunaite waiting for someone to notice it. As of late 2010, about 134 lunar meteorites have been discovered, representing more than 50 separate falls with a TKW of 46 kg, and around one in a thousand new falls that are collected is a lunar.

Re: [meteorite-list] Periodicity of Extinctions
Ed Grondine said: Now since the Nemesis Hypothesis has been thoroughly disproved, perhaps you'll send Morrison a note suggesting that he update this piece: http://www.csicop.org/si/show/is_the_sky_falling in which he thoroughly endorsed the Nemesis Hypothesis as the standard paradigm, while damning Clube and Napier. In fact, if you read the link given, you'll see that what Dr Morrison wrote 14 years ago was a review of a book in the popular press called 'The Three Big Bangs: Comet Crashes, Exploding Stars, and the Creation of the Universe', By Philip M. Dauber and Richard A. Muller Dr Morrison only mentions the NH in passing. Because Richard Muller is also a co-author of the NH. He tells us: This book is a good read, but should be taken with quite a few grains of salt. How you get thorough endorsement of the NH, from the admonishment to take something else one of it's co-authors participated in with a grain of salt is a mystery to me. But to say that book review is a thorough endorsement of the Nemesis hypothesis is untrue. And a classic example of the many intentionally disingenuous falsehoods of Ed Grondine.

Re: [meteorite-list] Periodicity of Extinctions
Hi Sterling, Richard, all - First off - Why should this be the Great Dismal Swamp? Why do some people have a hard time talking about cometary injection mechanisms? Second - Why do the impact hazard charts NASA provides to the Congress show a 100 year random average occurrence, instead of the actual 26 million year periodicity? As far as smaller impacts go, why did NASA not fund the determination of cratering rates from the data for other bodies, data which NASA had for years? Third - why the hell isn't NASA funding YD comet impact studies? Now to the academic side of things. When I called this process periodically chaotic a few folks did not like it. I see you are stuck for words as well. Have you graphed out the residuals between periodic and actual time of occurrence? This 26 million year periodicity should be showing up on other planets (see my comment on NASA's total lack of work on this above). In particular, say, on the walls of Valles Marineris on Mars. Since WISE has pretty much shown that Nemesis does not exist, isn't far past the time when the Nemesis Hypothesis should be rejected? (And Morrison update his Sceptical Inquirer article?) E.P. Grondine Man and Impact in the Americas PS - Richard, I'd love to go on Coast to Coast AM and talk for a couple of hours about the Contempt of Congress shown by former NASA Administrator Griffin in his deliberate failure to comply with the George Brown Jr amendment.

[meteorite-list] mercury escape numbers? can it be this?
I don't post much. I did not do the math. (my calculus has not been used much for many many years. would not if you had a highly highly elliptical orbit not have to have the full sun escape velocity as it could do the whip around gravitational boost effect from the sun. also would a highly elliptical orbit have less of a escape velocity? the second part could be wrong but the first one is always a possibility. (at least in my mind) :) -Rex Scates scalecubes.com But what about Mercury. Mercury's escape velocity is 4.3 km/s. But it's downstream from Earth and the Sun is a huge gravitational drain plug that devours material. If you think Earth gets a piece of Mars, imagine what the Sun gets from Mercury. To escape the Sun ... that is to go upstream towards Earth, at Mercury, any fragment would have to battle an escape velocity of 67.7 km/s. That's greater than Jupiter ! You might say ... ok, you don't have to actually escape the Sun, only make it from Mercury to Earth. Well, at Earth, the escape velocity is 42 km/s from the Sun. That's a loss of 25 km/s ... and don't forget the extra 4.3 km/s to get away from Mercury as well ... __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Here is another one. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemitem=310336142374ssPageName=STRK:MEWAX:IT I suppose if I posted all the scams on Ebay, it would crash the server! It's to the point of being ridiculous. I thought Ebay had rules for authenticity. The responses you get from these sellers, is a riot! Everyone ought to be challenging these sales. I was contacted by a person who was scammed. His purchase streaked red in a clean window! While the seller is refunding his money, that just adds to the evidence these sellers do not know what they are selling. And they are suppose to know what they are selling...it's an Ebay policy.

[meteorite-list] CA meteorwrongs + Cat Mountain redux
Hi Count, Right away you can tell that the this piece is probably a meteorite..although methinks it ain't an iron...by the experienced guys who are commenting on this post. Surely you jest! ;-) Or you're poking some good-hearted fun at experienced guys because of the feedback you got about your Cat Mountain. (Though you can't lump Mike Farmer and me into the group that said that ~your~ find wasn't a meteorite, 'cuz I don't believe either of us commented on it.) In any case, I don't mind risking what little reputation I have by saying these California finds aren't meteorites. I've seen these roasted meteorwrongs enough times in the Mojave Desert that I no longer bend over to pick them up. So, if you fellows will let me...I'll take a crack at buying it and see if my luck is still holding up since last weekend. I applaud your optimism! On the plus side, you should be able to get one of them pretty cheap since I don't expect a bidding war to ensue. ;-) I say luck as I'm getting ready to make another announcement of an even larger find of Cat Mountain then the one I got 3/23/11...initial analysis looks good. A 170 gram individual and some questionable smaller pieces. Fantastic! Good for you! You fellows are missing out by not getting down to Snyder Hill in Tucson. Only one hunter there last weekend. Lonely. Tough time of year to be hunting. I expect you'll have more company come late autumn. I've been meaning to ask about your Cat Mountain 001 designation. Is this expected to become a synonym for Cat Mountain (since your initial find is clearly paired to the original)? Presumably the only reason one would start a numbered series is if one or more unpaired meteorites have been found in the same general area. Congrats on your latest find(s), Rob __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] mercury escape numbers? can it be this?
Hi Walter and great to see you still active on the list, also Sterling and Mark and ET and all listers Rex is referencing my comment on the escape velocity from the Sun, in addition to the escape velocity from the planet. I.e., the closer you are to the Sun, the greater the escape velocity at that distance. Perhaps I was a bit sloppy, since in fact escape velocity is not the exact measure needed to get from the Mercury to Earth (note: escape velocity from the Sun's grip at Mercury to the Sun's grip at Earth), but rather a significant part of it. It is conveniet however to think of escape velocity. The same is true for Earth, for example, if you are at the Moon's distance, the escape velocity from the Earth is only 1.4 km/s instead of the often quoted 11.2 km/s from Earth's surface. Escape velocity depends upon the mass and distance from the center of mass as well of the primary object, but as you note it is normally thought of fromm something being launched from the surface. In this case, thought, it is the Sun's escape velocity that trumps everything, incluiding Mercury's surface escape velocity. Since Rex is correctly observing (as I also mentioned in my original post) that in an eccentric orbit you can play with the gravitational potential energy so that you are further away from the Sun, the escape velocity from the Sun at Earth's distance if that is where the semimajor axis of the ellipse reaches will not be the barrier. The question to ask at that point is how something smashing into Mercury in the first place - when all of Mercury's momentum is in the orbital direction. So, you there is no easy escape from this conumdrum in my opinion. As was already covered very effectively by Mark (and also covered in my original post, and to some extent by Sterling when we discussed moving orbits in the asteroid belt some time ago) the energies required to change orbits are on a huge scale. So if we treat this as a delta energy and pay close attention to the velocity vectors, the correct question to ask IMO is in order to change the energy from a Mercury orbit to deliver it here on Earth, how do you flip the velocity vector enough to send it here without channelling such a great amount of energy into the rock that it completely changes form. How would you throw a tennis ball out the window of your speeding car (even without air resistance to deal with) and get it to peacefully go on its way in a perpendicular direction? As for the Canadian modeling, Sterling I respect the modelers and have been there and done that myself, well in material property situations -not orbits. But, letting the computer plug and chug while we all chug our own cold ones is not enough unfortunately. With all modeling, a few basic assumptions are made; with all published work on modeling, even though the authors say generally the assumptions, it is not always so hermetic that one can reproduce identically. I welcome their addition to the literature, had not heard of it before...but what I will say is it is *NOT* an *ab initio* calculation that they have done, and I would need to see all the fudge factors to properly criticize such a work. It does bring up good questions and comments as a tool - but it doesn't change the physics of the situation. If I had more time I would get into it, but at the moment I am luck to find time to type this poorly thought out comment. Kindest wishes Doug Regarding ET's specimen, whether or not it is from Mercury has little impact on its incredible status. Not being from Mercury (IMO) is in fact more exciting because we aretalking about a completely different parent body that holds more of a key to unraveling what happened in the larger bodies in the evolution of the Solar system. -Original Message- From: Walter Branch waltbra...@bellsouth.net To: rexsca...@comcast.net rexsca...@comcast.net Cc: meteorite-list@meteoritecentral.com meteorite-list@meteoritecentral.com Sent: Fri, Aug 5, 2011 1:34 pm Subject: Re: [meteorite-list] mercury escape numbers? can it be this?

[meteorite-list] Ad - Carbonado Impact Diamonds, Suizhou, Long Island, Saratov, Impactites (shattercones, breccias), and more!
Hi Listees and Collectors, I have acquired a small lot of rare carbonado impact diamonds. These come from the deposit in Brazil and it is thought that these diamonds originate from a 2.8 billion-year-old impact. A large asteroid slammed into the Earth when South America and Brazil were still united as one continent. There are matching deposits of these diamonds in Brazil and Africa from when these landmasses were joined. This type of black carbonado diamond has odd properties and a strange appearance compared to the more familiar type of gem diamonds. I have never offered these for sale in the past and the only one I had was a large specimen in my personal collection. Now is your chance to own one of the most exotic and unusual forms on diamond on Earth without breaking the bank on a large specimen. See the link below for more details, photos, and ordering. Don't forget to use coupon code metlist for 20% off your purchase. http://www.galactic-stone.com/product/carbonado-black-diamond-ancient-impact-artifact I also have new micromounts of : Suizhou (L6, China, Witnessed Fall 1986) Saratov (L4 Russia, Witnessed Fall 1918) Long Island (L6 Kansas, Find 1891) Introductory price on those are $5 each with free shipping.

[meteorite-list] View from the Summit: Hunting for KBOs at the Top of the World
http://pluto.jhuapl.edu/news_center/news/20110805.php View from the Summit: Hunting for KBOs at the Top of the World John Spencer New Horizons August 5, 2011 John Spencer is a member of the New Horizons mission science team, and the coordinator and self-described cat-herder-in-chief for the effort to find a Kuiper Belt object flyby target for New Horizons. I'd like to tell you a bit about our recent Kuiper Belt object search observing run on the Subaru telescope on Mauna Kea Observatory in Hawaii, one of a dozen or so KBO search runs we're doing this year. But first, I want to thank everyone who's helping out with the crucial task of sorting through our terabytes of data for those elusive KBOs, using the Ice Hunters http://www.icehunters.org/ site! It's amazing the effort people are putting into this, and I hope we can all reap the rewards sometime in the coming decade, when we get mankind's first look at one of the typical members of the Kuiper Belt. I used to go to the telescope all the time, starting when I was a postdoc at the University of Hawaii - Mauna Kea was where I learned the ropes. But these days I spend most of my time working on space missions - a thrilling business, but one where you do your observing at your desk, or in teleconferences, or at meetings, thrashing out the details of observations to be made millions of miles away and relayed back to your computer for analysis after the fact. When I do use Earth-bound telescopes these days, I usually do it over the Internet, controlling the telescope from my desktop thousands of miles away. For the KBO search effort, I've mostly been helping to plan observations to be made by other teams, at the Subaru or Canada-France-Hawaii telescopes in Hawaii, or at the Magellan telescopes in Chile. So I was excited at the prospect of going back to Hawaii in person for one of our Subaru runs. Even then, I expected to be operating the telescope from a control room in Hilo at the base of the mountain, not from the summit - it's logistically easier to observe at sea level, and astronomers' brains work better at 2 a.m. if they're not starved of oxygen at 13,500 feet. But it turned out that Subaru had a staff shortage, and wasn't able to field two of its own people to be on the summit, at the telescope itself, for our run. That's a problem, because working alone overnight in such a remote place, amid such massive equipment, is not only lonely but dangerous, and observatory rules require at least two people at the telescope at night. So we astronomers (myself, Dave Tholen from the University of Hawaii, and Dave Trilling from Northern Arizona University, plus our assigned Subaru support astronomer Miki Ishii) had to be at the summit too for our two-night run in early July. This was good news as far as I was concerned - I didn't mind braving the altitude and the remoteness if it meant being able to recapture some of the romance of the old way of connecting with the universe, up there on the mountaintop. So, on June 30, after the long flight from Denver to Kona, I left behind the coconut palms of the Hawaiian coast and drove 9,000 feet up the mountain to the observer's dormitory. The dormitory, Hale Pohaku (Hawaiian for stone house), is perched near a tree line on the flanks for Mauna Kea in a scrubby forest of native mamane trees, with a stunning view of the vast bulk of the volcano Mauna Loa to the south. Hale Pohaku used to be my home away from home, but I hadn't been there for eight years, so it was great to be back and slip into the familiar old routines, and see familiar faces. Joining us at the dormitory was a film crew from the New Horizons team at the Johns Hopkins Applied Physics Lab, who were filming a piece about our observing run that I hope you'll soon be able to watch at this site. After a night and a day of acclimatization, adjusting our bodies to the thin air, we climbed into 4WD vehicles and made the half-hour drive to the summit as sunset approached. It is always an amazing transition from the relative domesticity of Hale Pohaku and its mamane trees to the vast, alien, apparently lifeless landscape of the summit and its giant telescopes. This was the first time at Subaru for some in our group, so Josh Williams, the telescope operator, gave us a quick tour of the darkened, cathedral-like space of the dome, almost filled by the huge bulk of the telescope with its 8-meter diameter mirror. We also made quick trip around the catwalk outside the dome, to admire the fabulous view, before returning to the warmth and comfort of the control room, where we were to spend the night. After the sightseeing, it was down to business. We made some calibration observations of the evening sky, and then had about an hour to wait until the part of the sky where we knew our KBOs were hiding rose high enough for us to look at it. We had a quick look at a couple of near-Earth asteroids (NEOs) while we were waiting, to check their locations
[meteorite-list] Mars Rover Opportunity Update: July 29 - August 4, 2011
http://marsrovers.jpl.nasa.gov/mission/status.html#opportunity OPPORTUNITY UPDATE: Nearing First Landfall of Large Crater - sols 2670-2676, July 29 - August 4, 2011: Opportunity is now only about 120 meters (394 feet) from Spirit Point, the first landfall on the rim of Endeavour crater. The rover drove four times in the last week on Sols 2670, 2671, 2674 and 2676 (July 29, 30, Aug. 2 and Aug. 4, 2011), totaling over 370 meters (0.23 miles) of drive distance and exceeding over 33 kilometers (20.5 miles) in total odometry. The right-front wheel currents remain behaved. On Sol 2672 (July 31, 2011), Opportunity performed an overnight alpha particle X-ray spectrometer (APXS) spectrum of atmospheric argon. On Sol 2673 (Aug. 1, 2011), the rover used the autonomous AEGIS software to look for interesting outcrops. The AEGIS software was awarded the NASA 2011 Software of the Year Award. The plan ahead is more driving to reach Spirit Point. As of Sol 2675 (Aug. 3, 2011), solar array energy production was 385 watt-hours with an atmospheric opacity (Tau) of 1.03 and a solar array dust factor of 0.537. Total odometry is 33,227.58 meters (33.23 kilometers, or 20.65 miles). __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Mercury Meteorites - the short list
Hello again Mercury Nornoids, Physics, opinions and biases aside ... can we build a concise list of Mercury meteorite candidates already in our collections (at least wistfully) and play a game to see if we can speculate on them one by one - before the scientific press - with information from MESSENGER - as candidate meteorites from Mercury? Or, better yet, not eliminate one or more ... ;-) ? 1. Bencubbinites 2. Angrites 3. GRA 06128 06129 4. NWA 011 and pairings 5. Mercury Meteor (parent body Mercury or Ford?)
