Re: [meteorite-list] Barringer Meteor Crater (rescanned)
First off, many thanks for the many off list comments about my images. Had I know so many would like them I would have done a better job. One list member even used software to combine several of the images into beautiful panoramas. Now that I know there's interest in such things I went back and rescanned the slides using a much better scanner. It took a lot longer but I think most of the rescanned images look better. Somehow the scanner managed to electronically remove most of the dust and scratches.

Hi Abe, You got me so excited about the DVD release that I went to Amazon.com to purchase it and found that what there selling is on demand viewing of the episodes at $1.99 each.

Re: [meteorite-list] Meteorite Men in Canada
Abe posted: Is there any place that I can buy Season 1 and episodes of Season 2 online other than Amazon? Dear Abe, Todd, and all: Meteorite Men Season One is currently airing in Canada on the Discovery Science channel. I'm sorry to report that we do not yet have a DVD release date for any Meteorite Men episodes. When Steve and I were at Science Channel/ Discovery HQ recently, we asked again about this, but no decision has been yet been made. Season Two is not yet half-way through its premieres here in the US, so there's no chance of a S2 release until all the new episodes have aired. Once S2 has gone through its first run, there will be 15 Meteorite Men episodes total, including the pilot, so our hope is they may do a boxed set release of all of them. I will certainly post news to the M- List when we have it. As for the Amazon downloads, you can watch them directly on your computer, without the need for any additional hardware. The image quality is quite good for the pay-per-view episodes (and there are no ads!), so that is at least one option for you. One of you asked how to find out which episodes you might have missed, and you may find our Meteorite Men Episode Guide to be useful for that: http://meteoritemen.com/meteorite-men-episode-guide.htm Finally, we constantly post news about the show -- including air dates and overseas broadcast outlets, photos, etc. -- on our Facebook and Twitter pages, and invite you to connect with us there if you would like to know more: http://www.facebook.com/meteoritemen http://twitter.com/meteoritemen Thank you for your interest and we hope you enjoy the show.

Dear List, https://kb.osu.edu/dspace/bitstream/1811/4817/1/V61N06_341.pdf I found a very interesting PDF file report, of all iron meteorites found at all Archaeological sites across the county. It not only covers The Mound Builders, But other cultures out west and in Mexico, Canada. I do not condone anyone disturbing archaeological sites or Scared Buial Grounds. But Being facinated with the Mound Builders and meteorites I found the report to be very interesting. Native Americans were as interested in collecting meteorites as we are today. I Grew up in Butler County Ohio, and that county had over 300 earth works and mounds pre 1850. It is sad that there is less then 30 left standing today in Butler county. It is a great read if your interested in Archaeology and meteorites. dave __ 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

This cooling rate has been calculated for the Tucson Iron ring meteorite to be in the order of 1 degree C per one thousand years. This again is considered a rapid cooling rate. No, nothing makes much sense if you believe what they say that hailstones the size of golf balls to basketballs hit this craft.

Re: [meteorite-list] NASA Announces Comet Encounter News Conference
With all due respect Carl, please stick to talking about meteorites which you know about it and leave stuff about comets that you know nothing about to the cometary scientists. It is rather unfortunate that when scientists use or reuse everyday terms like ice, that people interpret that to mean ice cubes like in their freezer. When in fact, ice is the technical term for frozen volatiles including H2O, CO2, etc... And how ice behaves in space is going to be different than how it behaves in an atmosphere under pressure and subject to gravitational forces. If comets were in fact fiery hot, we would have several lines of evidence showing that and we don't. All of the evidence shows that comets are cold and that when close to the sun, the ices sublimate. Which ices sublimate when is a factor of distance from the sun, how fresh the comet is, and lots of details that get boring real fast. Out in space, I can imagine that it is very easy to get fluffy large snowflakes that we wouldn't see here on Earth. Snowflakes is also not a good word to use, but we have no other words to describe the things we are seeing, so we use the closest words that we have. Why didn't these fluffy things damage the spacecraft? Mostly because most of the fluffy things we were seeing were fairly close to the nucleus and not 400 miles away like the spacecraft was. As the fluffy aggregates of ice and dust get further away, the ices continue to sublimate and the fluffy aggregate eventually breaks apart into the tiny tiny dust particles. Basically, we have spectroscopic maps (the distribution maps that have been posted) showing both water vapor and water solids. They are not coming from the same places on the comet. I was going to point out how the Inuit have multiple words for snow only to find out that they have no more than we do. The article though is still interesting and.. relevant... http://en.wikipedia.org/wiki/Eskimo_words_for_snow Comets as objects are not something that we experience in our everyday lives. Therefore, their parts and structures may not have everyday equivalents. Therefore, we use words that are similar and closely describe what we see and give those words new meanings. Another classic example in astronomy is the use of the word umbra. It means shadow. When early solar observers first saw sunspots, they thought those were shadows they were seeing so they used shadow terminology. We know now that sunspots are not shadows, but to come up with brand new words to describe the parts of a sunspot... well, umbra and penumbra stuck. Clear Skies! Elizabeth Warner EPOXI webmaster cdtuc...@cox.net wrote: Larry, Chris, All, All due respect here but, Smoke is very fine dust. To your point I must agree that the eraser example is perfect. see link to latest info about Comet Hartley 2; http://www.foxnews.com/scitech/2010/11/19/spacecraft-flies-past-snowstorm-comet/ According to this news. They are now saying that this stuff spewing out of these jets is fluffy ice. This seems to me to be a classic case of 'Manipulating the facts to fit their original hypothesis'? They think comets are icy. They claim that this material moving at 27,000 MPH did not cause damage to the craft because it is soft fluffy ice. I don't know just how fluffy ice can be but golf ball to basketball size fluffy ice objects hitting something while moving that fast does not sound like fun. Now on the other hand. If this is just smoke it is easier for me to understand why no damage was done to the craft when the craft flew through the debris left by the Comet.. So, it in deed seems to me that as Larry pointed out this stuff is not ice but is smoke. We don't have to force this result to fit any ice theory. Further, in the pictures the jets appear to be everywhere. Not just at the tail end. And the reflected light appears to be illuminating parts of the surface equal to the brightness of the jets which would seem to indicate a highly reflective substance like metal. To further this theoretical possibility. In the only gathering of actual comet dust they were able to determine that a metallic mineral Manganese / silicate was in fact spewed out of the comet. This was later named Brownleeite and is now considered to be a new mineral. So, in Sum, this thing looks like it is spewing out smoke (very fine dust). Isn't this possible? Why does it have to be Ice? Many objects out in space are fiery hot. Hot stuff is out there. Look no farther than our own Sun. Why according to NASA do comets have to be cold? These pictures are the only close -ups we have and they say. This is one hot chicken leg. And the conclusion should not be forced. Let the facts speak for themselves. Sorry but, I think Ice is hard not fluffy. Especially at 27K miles per hour. IMHO.

Re: [meteorite-list] NASA Announces Comet Encounter News Conference
It is 100% certain that comets are not hot inside. Surface temperatures depend in part on the emissivity of the material; these low albedo surfaces might reach temperatures of a few tens of degree Celsius, if they are in a passive area where you don't have evaporation carrying away heat. I think you are misreading the report. The carbon dioxide jets are not being driven by water vapor. Water vapor is seen in the jets of other comets. In the case of Hartley 2, the jets are CO2, which are able to eject still frozen water crystal aggregates. While some of these were of a centimeter scale, they were extremely low mass, which is why they didn't damage the spacecraft. They were the SIZE of hailstones, but not the DENSITY of hailstones.

[meteorite-list] FW: Native American use of meteorites
I find the Hopewell use of meteoric iron fascinating -- they beat it into foil (more or less) and used it to cover the surfaces of more mundane materials. Apparently some relatively intact meteorite chunks were found in burials, more as trade goods than objects of veneration -- the Hopewells were collectors too! Has anyone ever done comparisons of the meteorites found in Hopewell mounds and existing collections? Since several of the Hopewell meteorites were pallasites (and we know how uncommon that subgroup is) it should be relatively simple to determine which pallasite they are associated with. That would both give us another marker about their trade networks, and benchmark for when the pallasite fell, since the fall obviously predates collection, although the events are not necessarily contemporaneous. __ 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] NASA Announces Comet Encounter News Conference
Vapor is the evaporation of boiling liquid water. And that is the only possible source of water vapor?? So, have you ever been in a cloud? fog?? What was boiling to make those then?? Again, your limited experience with how materials behave on Earth in atmosphere, under pressure and with gravitational forces is blinding you to the fact that materials can and do behave differently in space. Water might boil at 100 C at sea level, but in space it boils away at very low temperatures. http://www.newton.dep.anl.gov/askasci/chem07/chem07192.htm Vapor in the context given by the EPOXI scientists refers to H2O (and other materials) in a gaseous form. Ice would refer to that material being in a solid form. That solid form does not necessarily mean it is a block of ice like an icecube. And I'm sure you've heard the riddle of what weighs more: a pound of feathers or a pound of lead? They weigh the same, but you are going to need a whole heck of alot of feathers to get a pound!

Re: [meteorite-list] NASA Announces Comet Encounter News Conference
Elizabeth, Bob, Chris,All, This has been a very helpful and educational thread for me and I'm sure a few others.Unfortunatl, It seems that everybody is using old scientific information to explain all of this. So, let me ask one more question; Is their anything to be learned by these pictures of Hartley 2 that we did not already know or not? I mean can anyone relate this to what to look for in a cometary meteorite find or fall back here on Earth? As you all well know . I fully admit that I know nothing about space. My only interest in space is how it relates to meteorite material and hunting. This because I will never go to space but, I may find an important Cometary meteorite so, I would like to know what to look for. It seems that even though a new mineral was found in comet dust called brownleeite. This being a manganese silicate. You would expect this would have opened up the Science of space . But as far as I can tell it has not. I mean what was the significance of this fact and the close-ups of Hartley 2 if we don't establish and then publicize new information? Even The Carancas Fall and Crater began to re-write some of the books about impacts until it was decided that that was just an exception. Exception it may be it still caused a huge crater and remember we are talking about a meteorite so delicate that it is easily crushed between two fingers. And still it created a huge crater.

I suppose it depends upon what they are made of. Iron might stay hot longer than mica for example. And or, Perhaps they contain some source of renewable energy source within them? .

[meteorite-list] Shallow Groundwater Reservoirs May Have Been Common on Mars
NEWS RELEASE FROM THE PLANETARY SCIENCE INSTITUTE SENT: Nov. 22, 2010 FROM: Alan Fischer Public Information Office Planetary Science Institute 520-622-6300 520-885-5648 fisc...@psi.edu Shallow Groundwater Reservoirs May Have Been Common on Mars An international research team led by the Planetary Science Institute has found evidence for reservoirs of liquid water on Mars at shallow crustal depths of as little as tens of meters. J. Alexis Palmero Rodriguez, research scientist at PSI, and the research team came to this conclusion after studying collapsed terrains that occur within some of the solar system's largest channels. Investigations of similar but vastly larger zones of collapse located where these channels initiate have led previous investigations to postulate that the upper crust of Mars contained vast aquifer systems concealed underneath a global frozen layer kilometers in thickness. However, these zones of large-scale collapse are rare on Mars and their formation most likely took place under exceptional hydrogeologic conditions. The PSI-led team's work documents the distribution of groundwater within crustal zones located beyond these regions. Citing geologic evidence found in the planet's largest system of channels located in southern circum-Chryse and results from thermal numerical modeling, Rodriguez and his co-authors propose in an article published in Icarus that groundwater reservoirs may have been common within the Martian upper crust. The numerical model implies that where fine-grained, unconsolidated sedimentary deposits existed on top of an icy permafrost layer, melting of ground ice and the development of subsurface aquifers could have taken place at shallow depths. Extrapolations of their results to the present Martian conditions imply that groundwater may currently exist underneath thermally insulating fine-grained sedimentary deposits approximately 120 meters in thickness. Thus, despite large differences in hydrogeologic histories, average surface temperatures, and internal heat flows of Earth and Mars, some areas of Mars might be similar to typical permafrost on Earth, where shallow aquifers are confined by thin layers of icy permafrost. These reservoirs could mean the presence of accessible water near the Martian surface, Rodriguez said, which could greatly reduce the costs of future manned exploration of the planet. In addition, it could mean habitable environments may exist at shallow depths, he said. This research was funded by a grant to PSI from the NASA Mars Data Analysis Program.

Re: [meteorite-list] NASA Announces Comet Encounter News Conference
Well, you ended up asking several questions... Is their anything to be learned by these pictures of Hartley 2 that we did not already know or not? Ahh, I think I'm starting to see where some of the confusion lies. You are operating under the assumption that everything we know about comets we know as an absolute fact... Well, for the most part yes, Yes, comets are essentially dirty snowballs. Dusty snowballs might be better. Some are dustier, some are snowier. But there are a lot of details that are getting glossed over in that summary that the public doesn't care about. And while we knew from various studies that comets are dusty snowballs, most of those observations were indirect or derived results. With Hartley 2, we *see* the CO2 jets spewing out H20 snow... we finally *see* the snow! It's not just spectroscopic distribution maps, spectra, etc. We can trace the jets we see in the coma down to features on the nucleus. We *see* what is going on rather than just inferring. So, yes, we learned new stuff! These are scientists. They are looking for information. We have gotten tons of data, but it is going to take more than just 2 weeks to properly process/analyze/understand it all. Theories will get revised/updated accordingly. We've posted what we can. The details will get written up in the journals and properly peer-reviewed and published. And then you'll have plenty to read. Have you bothered to read any of the papers published about Tempel 1 after Deep Impact? So the information is out there, you just haven't read it. Likewise, the info about Hartley 2 will eventually get published, but will you actually read it? As for your second question I mean can anyone relate this to what to look for in a cometary meteorite find or fall back here on Earth? I don't think that any scientist expects to find cometary meteorites because based on what we currently know about comets, they are simply to fragile and volatile to survive the atmosphere. Maybe when Rosetta reaches comet C-G and lands on it, we'll know more. Clear Skies!

Re: [meteorite-list] NASA Announces Comet Encounter News Conference
Elizabeth, You express yourself much better than I do but, I still don't get your reasoning. It seems you are very quick to accept that what you *see* is dusty snow and CO2 jets spewing out H2O snow and you may be right. So, wouldn't catching actual manganese silicate material spewed out of a Comet tell you at least as much about the make up of a comet as what the *visual only* of the H2O tells you ? I mean if these jets are spewing out H2O from these jets and that leads you to conclude that this comet is made up of H2O then if you know for a fact they also spew Manganese / silicate. Doesn't that offer even greater evidence than a mere *observation* of H2O does? We *captured* Brownleeite (manganese silicate) and we *observed* H2O!! Which scenario holds more weight for proof ? I would thing the verifiable physical evidence would be much more telling about what these comets are made up of And yet no mention of a comet found on earth may have a primary make up of manganese by anything I have read so far? Additionally, To me this suggests that the Manganese being much stronger than H2O might be all that would survive of a comet meteorite. Maybe this tells us we should be looking for manganese meteorites to be tested to see if they are cometary in origin? I mean testing the isotopes in these manganese meteorites may just surprise some of us? But , again. Only NASA Scientists can do this testing. If I were to find a manganese meteorite do you think anyone would help me get it tested?

Re: [meteorite-list] NASA Announces Comet Encounter News Conference
Carl- I'd argue that we have not captured MnSi from any comet. We have captured it from the interior of interplanetary dust particles. Those particles were collected during an influx of dust from one particular comet, and are reasonably inferred to be constituents of that comet, but that is not absolutely certain. And assuming that they are cometary, the amount of MnSi is exceedingly small. I can't see any grounds for thinking it contributes more than a trace amount of the total material. This is in contrast to CO2, H2O, and other ices which have been observed to constitute a large fraction of the total mass of an active comet. Those observations consist of direct reflectance measurements of comet nucleuses, as well as of gases in the comas and tails.

[meteorite-list] Temperature of meteorites
Hi all: I am in the middle of a workshop on asteroids and meteorites. At the end of the first day, the teachers get to write down questions that they would like answered. During the session, I had said that when they land, meteorites are cold, not burning hot. The question that was asked was how cold? What is the best estimate we have for the ambient temperature of meteorites after they have passed through the atmosphere? Thanks.

Re: [meteorite-list] Temperature of meteorites
Hi, after glowing off, the small size meteorites passes thru Stratosphere with temperatures of minus 60 °C in winter and -10°C in summer. During their minute-flight thru the atmophere they warm up to normal temperature. Only large objects which fly til the ground with hight supersonic speed (like Sikhote Alin) contact the ground with temperatures above 500°C. What I will say, the temperature depends on the landing speed. If it is the normal velocity of fall of earth gravity the meteorite is cold, if it is supersonic speed, it could be very hot. m42protosun -Original-Nachricht- Subject: [meteorite-list] Temperature of meteorites Date: Tue, 23 Nov 2010 00:34:24 +0100 From: lebof...@lpl.arizona.edu To: Chris Peterson c...@alumni.caltech.edu Cc: meteorite-list@meteoritecentral.com Hi all: I am in the middle of a workshop on asteroids and meteorites.

Re: [meteorite-list] Temperature of meteorites
I don't think there is a general answer to that question. It depends heavily on the size of the body after ablation. The larger it is, the longer it will take to cool down as it falls for a few minutes through cold (around -40°C) air. So a large body will be closer to the temperature it was at in space, which might be anywhere from 50°C or so down to a few tens of degrees below zero. Further complicating things, the outer surface might be near ambient temperature, while the interior is much cooler (or occasionally warmer). The few reports I've heard of meteorites forming frost after they fell were in cases where they split open.

Re: [meteorite-list] Temperature of meteorites
Are there ANY photos of any meteorite, taken *immediately* after it fell? Within seconds, or even minutes? I know some people have reported meteorites as warm, (e.g. Peekskill). http://astro.wsu.edu/worthey/astro/html/im-meteor/strikes.html and http://www.amnh.org/exhibitions/permanent/meteorites/what/index.php Then this: http://www.mail-archive.com/meteorite-list@meteoritecentral.com/msg42288.html and I'm sure there are others... So is it that all meteorite falls are different and variable with regards to temperature at the time of fall and is this why there is no definitive answer to the Hot/Cold question? Is it because some are warm, and some are cold? Does it depend on angle of descent, speed, and composition of the body? All of the above? Does the weather/temperature in the area of the fall have anything to do with the temperature of the meteorite at the time of impact? Lots of questions to ponder...

[meteorite-list] Saw another fireball a little bit ago
We need an all-sky camera in my neck of the woods... I just saw another (small) fireball. It was orange/red. I first saw it a little to the west of Montrose at about 45 to 50 degrees above the horizon and it appeared to be on a path almost due north. It traveled until I would say it was at 10 to 15 degrees above the horizon from my view point, then looked to have disrupted and then quickly went dark. No sound from it that I could hear but that's not saying much because I have tinnitus terrible bad tonight. My wife had called me to come outside to listen to a really high pitched sound she could hear when she was on the north side of the house. Turned out to be an alarm going off in our 5th wheel sitting in the driveway. As I was standing out there in the front drive trying to figure out that sound, that is when I saw the fireball.

On the warmer surface the carbon dioxide has already boiled away by the time the water ice starts to sublime. This means that the gas from below (C02) and the gas from the surface (H20) are coming off at the same time. But the jets of hot C02 (well, hot for C02!) are blowing chunks of ice off the surface even as they start to melt. Sterling K.

Perhaps you did not read the NASA link I provided in my previous post. Here it is in case you missed it; http://www.foxnews.com/scitech/2010/11/19/spacecraft-flies-past-snowstorm-comet/ Again, all do respect here. To be clear my questions here relate to gaining the knowledge of what rocks to look for that might be of a cometary origin. Not to knock others opinions. I just want logical answers. The link does say they think it is water ice as opposed to other substances. They go on to say that jets of carbon dioxide *appear to be* fueled by water vapor. Vapor is the evaporation of boiling liquid water. But later say there are also large hailstone chunks to boot. I think it looks like hot dust (smoke) . They say some of the hailstorm of Fluffy Ice that hit the spacecraft may have been between the size of a golf ball and a basketball. This with NO damage to the spacecraft? Dr. A. Hearn also points out how different Comets are from one another. Aw Ha moment here? They are different! You ask. How could they stay hot? That is the big question. I suppose it depends upon what they are made of. Iron might stay hot longer than mica for example. And or, Perhaps they contain some source of renewable energy source within them? . A source that is yet known to us? How do we know whether they are cooling or not? That coupled with the fact that all things take time. Look no farther than the published cooling rates of iron meteorites. The Tucson iron meteorite is said to not display the widmanstten pattern on an etched surface primarily because in spite of the fact that it contains plenty of nickel, it cooled too fast. This cooling rate has been calculated for the Tucson Iron ring meteorite to be in the order of 1 degree C per one thousand years. This again is considered a rapid cooling rate. No, nothing makes much sense if you believe what they say that hailstones the size of golf balls to basketballs hit this craft. It had to of been smoke from the intense heat of this comet to have not damaged the craft. ice and even melted ice in the form of water at 27K miles per hour would have damaged the craft. Incidentally , I took a piece of coal in the dark and illuminated it. Sorry, but it looks nothing like the close-up pics of Hartley 2 and that is the comet we are talking about here. No antique distant pics from the past can compare with these new pics. We are in a new age of discovery and should give up these old and possibly obsolete photos and theories of the past. One more thing. If these so called infrared spectrometers tell us what this Comet is made of then I would love to hear it? Please spare me the Fluffy ice though. What other minerals are abundant on comet hartley 2? Thanks. Again. IMHO.
