[meteorite-list] nital and etching
Hello dear friends! I want to try to etching some iron meteorites and some mesosiderites, but I never try this! I have here nitric acid HNO3 at 65% and ethyl alcohol at 96% and now??

Re: [meteorite-list] Kenya meteorite
A great big CONGRATS to you guys for your hard work and your success!!! Mike had shared the news from his 1st trip with me earlier, but I am just now able to hear about the finds from trip 2 as I too am out of the country and have been without Internet access for the last few days. ( Not meteorite hunting this time. :-) Anyway, like I said, congrats on another great successful recovery, Mike! Thanks for sharing the story with us all. Robert Woolard Sent from my iPhone On Aug 24, 2011, at 9:28 AM, Michael Farmer m...@meteoriteguy.com wrote: A little more background on the fall, First want to thank Greg Hupe who went with me for trip #2 less than a week after trip one. I wanted to get more money, get the first stones home safe and in the lab and back to Kenya. I had to cancel another trip planned for months with Greg, so only proper thing to do was invite him. He was most accomodating of the rapid change in continents we were going to visit when he saw the stones I got from the first trip. Congrats to Robert Ward who also recovered a stone in the field, saving it from sure destruction under tropical rains. We had a lot of fun, we also worked our asses off, dawn to dark, endless hours of every day stuck in traffic jams just to reach the strewnfield. Cobras, yes, I am not kidding, Greg had close encounter with a Cobra that stood up and scared one of our workers nearly to death, he ran from the field, Greg went to see it but it went down a hole before he saw it. Place crawling with snakes, I was of course in shorts:) so after the worker came screaming to the car, I left the field myself for safer quarters. The people were nice, the secret police found us, threatened us, got to the point and demanded their cut of the payday to allow us to work. The usual in Africa, another day, another shilling. I paid great money to the locals, either for stones or for workers and supervisors to monitor the workers, money none of them could refuse, most of them got a year or years of salary for stone worthless to them, changed their lives. For example the woman who sold me the 3.5 kg stone bought cows and pigs, went back to give her photos I promised her, she told me she invested some of the money in livestock, she bought 4 piglets and told me in a year she would have 20 pigs. she could not afford a single pig before that meteorite fell and like a gift from heaven, she got more money than she had ever seen in her life. I will not sell it. More than one month after the fall, hundreds of deperately poor people searching, 11.8 kg has been found plus the ~2.5 kg original mass. I thought more would be found, but not so easy. I flew 39,224 miles, spent more than $28,000 on expenses, went on safari, saw things I have never seen, and recovered a meteorite for science and collectors alike. Hopefully this is a good thing, but sadly I am sure some will try to destroy my work. Thanks for the support from those who like what I do to get you the things in your collections. Trying to work on a webpage, but my computer will have none of it, so giving up for the day. Will try again tomorrow.

Re: [meteorite-list] 25143 Itokawa and meteorites
Isn't this exciting news Al Martin! Al from wikipedia: S-type asteroids are of a siliceous (stony) composition, hence the name. Approximately 17% of asteroids are of this type, making it the second most common after the C-type. and from the Nature link: S-types are commonly found on the inner fringes of the belt, So it is not fair to call puny Itokawa even one of many parent body asteroids; only that a reasonable composition match for LL chondrites was found in what might be representative of its surface dust. The asteroid is only 2 X 2 X 6 city blocks in size or so ... but interesting since its orbit gets closer to our neighborhood. There is a case for all Vestoids being from Vesta, but such a common origin has not (yet?) been identified for S-type asteroids. With the exception of Vesta, no asteroid parent bodies are suspected with any certainty to be such grand-parent bodies. Grandparent, meaning it is directly linked ... rather than one of a billion possibilities.

Re: [meteorite-list] 25143 Itokawa and meteorites
Thanks David for the reply, Al, Martin, Listers, As for Vesta, because it is differentiated, it is unlikely to have any intact chondrules to source, but as an HED source, its the best bet we've got for parent bodies. Like you say, Itokawa is so small and already considered a rubble pile. Just to think all that rubble assembled there, and how many other asteroids seem to share its class, yet on another scale, it would be like the Native American's asking Colombus if he were the parent body for all the Europeans just because they met him (first)!

Dear List, this is pretty serious and relevant to the meteorite trade: Looks like PayPal slipped one quietly past us: No more $5.00 eChecks, now they charge the same fee on everything, whether from a credit or debit card, your money in their custody, or now just to broker a check out of your bank account. Effective Date: Jul 12, 2011 • Amendment to the PayPal User Agreement Purchase Payment Fee cap for Sellers who receive eCheck payments. If you are a Seller, your Purchase Payment Fees are set out in Section 8 (Fees). Currently, your Purchase Payment Fee for eCheck-funded payments is capped at a maximum of $5.00. After the effective date listed above, this $5.00 cap will no longer be applied.

Receive it about 3 business days later and deposit it at your convenience, then mail out my meteorites when it's cleared to your satisfaction. That will save you $9.70, and give me the satisfaction of knowing the transaction fee fell to $0.30 for you.

Dave is not able to post at the moment, and rather than rewriting this I am forwarding it for him. Obviously I had concerns about specimen transport prior to acquiring the meteorite in Conception Junction -- not because the landowner wasn't credible, but rather because it was possible a the stone was transported by a native American, perhaps centuries ago. It's hard in photographs to notice this at first, but the average crystal diameter of Brenham specimens we used for comparison was about 7.5 millimeters, whereas Conception Junction averages only about 4.5 millimeters. It's painfully obvious in a direct comparison that the two are quite different based on physical characteristics alone (including several factors, not just crystal size). Then of course there are the findings of UCLA's Dr. John Wasson, the world's authority on iron and pallasitic meteorites, which are detailed in the monograph through his contribution to same. To summarize, he wrote, The information I report here shows there is no main group pallasite that is closely related to Conception Junction.

Re: [meteorite-list] 25143 Itokawa and meteorites
Hello Craig: The theory of a single large object being pulled apart (or exploding as with Krypton) was shown pretty much proven wrong more than 30 years ago. If one looks at the various classes of asteroids, their distribution in the asteroid belt, and potentially related meteorite types, one finds that most of the objects in the asteroid belt and the meteorites derived from them were never larger than a few hundred kilometers in diameter, HEDs being the exception and even then, still less than 500 km in diameter. It is likely that Ceres, Pallas, and Vesta were the largest object to have survived planet formation (in the asteroid belt, as there are bigger things in the Kuiper Belt) and these also survived subsequent breakup. Larry PS It is very possible that we do not have any meteorite samples from Ceres as it is not near any resonances that would transport pieces to Earth-crossing orbits as we see for Vesta.

Re: [meteorite-list] Conception Junction
Bernd, Michael G., All, I see that Robert got a draft of this note out earlier, but I've added a little more detail here as well. Michael M. hit on part of this in his post, but you raised a reasonable question that we're happy to address. Obviously we had concerns about specimen transport prior to acquiring the meteorite in Conception Junction -- not because the landowner wasn't credible, but rather because it was possible a the stone was transported by a native American, perhaps centuries ago. It's hard in photographs to notice this at first due to a lack of perspective (even with a scale cube), but the average crystal diameter of Brenham specimens we used for comparison was about 7.5 millimeters, whereas Conception Junction crystals average only about 4.5 millimeters -- among the smallest of all known pallasites.

If one looks at the various classes of asteroids, their distribution in the asteroid belt, and potentially related meteorite types, one finds that most of the objects in the asteroid belt and the meteorites derived from them were never larger than a few hundred kilometers in diameter, HEDs being the exception and even then, still less than 500 km in diameter. It is likely that Ceres, Pallas, and Vesta were the largest object to have survived planet formation (in the asteroid belt, as there are bigger things in the Kuiper Belt) and these also survived subsequent breakup. Larry PS It is very possible that we do not have any meteorite samples from Ceres as it is not near any resonances that would transport pieces to Earth-crossing orbits as we see for Vesta. Hello list I still agree with the theory that almost all of the asteroids in the belt, were once part of a single planetoid, that was torn apart by the gravitational tug of war between the Sun and Jupiter. Also, people assume that the asteroid belt likes like the one from The Empire Strikes Back (Where Han Solo flies the Millennium Falcon INTO an asteroid field with hundreds of them bouncing off each other like a pinball game.) They are actually very far apart. Orbital distance is maintained via speed and mass because (Insert scientific techno-mumbo-jumbo here), so there's bound to be the occasional collision. It could be violent or it could be like a gentle touch. What reaches us here on earth, depends which piece of the pie got bumped our way this time. Also, is it possible that a fall in 683BC could also have a sibling fall in 2011 with both pieces being ejected from the parent body during a violent impact. One was travelling much slower than the other, and it took an extra 2694 years to get here. They would be identical (if it weren't for terrestrial weathering).

Approximately 17% of asteroids are of this type, making it the second most common after the C-type. and from the Nature link: S-types are commonly found on the inner fringes of the belt, So it is not fair to call puny Itokawa even one of many parent body asteroids; only that a reasonable composition match for LL chondrites was found in what might be representative of its surface dust.

[meteorite-list] Cassini Closes in on Saturn's Tumbling Moon Hyperion
http://www.jpl.nasa.gov/news/news.cfm?release=2011-266 Cassini Closes in on Saturn's Tumbling Moon Hyperion Jet Propulsion Laboratory August 26, 2011 NASA's Cassini spacecraft captured new views of Saturn's oddly shaped moon Hyperion during its encounter with this cratered body on Thursday, Aug. 25. Raw images were acquired as the spacecraft flew past the moon at a distance of about 15,500 miles (25,000 kilometers), making this the second closest encounter. Hyperion is a small moon -- just 168 miles (270 kilometers) across. It has an irregular shape and surface appearance, and it rotates chaotically as it tumbles along in orbit. This odd rotation prevented scientists from predicting exactly what terrain the spacecraft's cameras would image during this flyby. However, this flyby's closeness has likely allowed Cassini's cameras to map new territory. At the very least, it will help scientists improve color measurements of the moon. It will also help them determine how the moon's brightness changes as lighting and viewing conditions change, which can provide insight into the texture of the surface. The color measurements provide additional information about different materials on the moon's deeply pitted surface. The latest raw images of Hyperion are online at: http://saturn.jpl.nasa.gov/photos/raw/ . Cassini's closest encounter with Hyperion was on September 26, 2005, when the spacecraft flew approximately 310 miles (500 kilometers) above the moon's surface. Cassini's next flyby of Hyperion will be on Sept. 16, 2011, when it passes the tumbling moon at a distance of about 36,000 miles (58,000 kilometers). The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
