Re: [meteorite-list] Plymouth Meteorite
Interesting. I was actually referring to Keyser's son - here is small clipping I uploaded from a Scientific American clipping of 1895: http://spiralmemoprintsales.blogspot.com/p/blog-page_06.html --- Phil Whitmer prairiecac...@rtcol.com schrieb am Mi, 7.3.2012: Von: Phil Whitmer prairiecac...@rtcol.com Betreff: [meteorite-list] Plymouth Meteorite An: meteorite-list@meteoritecentral.com Datum: Mittwoch, 7. März, 2012 07:15 Uhr Regine: I remembered the story incorrectly. J.J. Keyser's age was not given when he found the Plymouth meteorite. According to Buchwald, he probably plowed it up in 1883. Ward gives the probably incorrect date of discovery as 1893 in his later catalogues. The story I heard was that Keyser gave or traded the meteorite (estimated by Buchwald at 13 to 15 kg as the actual weight was never recorded by Ward) to the Plymouth Oliver plow dealer where it sat on a desk on display in an office. Somehow Ward caught wind of an iron meteorite in Plymouth. I think maybe a relative of the plow dealer contacted him, I forget the details. Ward later cut up and sold the meteorite. I got to handle the Field Museum's Plymouth meteorite when Dr. Ed Olsen pulled it out of a drawer amongst about a hundred pounds of Murchison. There were piles of slices everywhere. My uncle and I talked extensively to Dr. Olsen about the meteorite. He shared several insights. Mr. Keyser told Ward about a larger meteorite in the same field, discovered in 1872. It was so big he was getting tired of plowing around it with his team of horses, so he and his son completely buried it, probably three or four feet deep, beneath the reach of the mold-board plow. (I'm assuming it was an Oliver plow, made in South Bend, Indiana) In 1894 Ward searched the field with a compass but found nothing. You would think he would have used a probe in areas where Keyser remembered burying the larger mass. The field has been extensively searched by many people using a variety of equipment. All searches have turned up nothing but bolts, bits of wire, nails, and other such stuff. Phil Whitmer --- It sounded so strange to me. But I do not know Nowak so I thought I'd ask before dismissing it. The original account of the guy living on the farm does on the other hand not sound completely absurd to me - he was not an old man when reporting to Ward in 1895. They went searching together.

[meteorite-list] NASA's Twin Grail Spacecraft Begin Collecting Lunar Science Data
March 7, 2012 Dwayne Brown Headquarters, Washington 202-358-1726 dwayne.c.br...@nasa.gov DC Agle Jet Propulsion Laboratory, Pasadena, Calif. 818-393-9011 a...@jpl.nasa.gov Caroline McCall Massachusetts Institute of Technology, Cambridge 617-253-1682 cmca...@mit.edu RELEASE: 12-070 NASA'S TWIN GRAIL SPACECRAFT BEGIN COLLECTING LUNAR SCIENCE DATA WASHINGTON -- NASA's Gravity Recovery And Interior Laboratory (GRAIL) spacecraft orbiting the moon officially have begun their science collection phase. During the next 84 days, scientists will obtain a high-resolution map of the lunar gravitational field to learn about the moon's internal structure and composition in unprecedented detail. The data also will provide a better understanding of how Earth and other rocky planets in the solar system formed and evolved. The initiation of science data collection is a time when the team lets out a collective sigh of relief because we are finally doing what we came to do, said Maria Zuber, principal investigator for the GRAIL mission at the Massachusetts Institute of Technology in Cambridge. But it is also a time where we have to put the coffee pot on, roll up our sleeves and get to work. The GRAIL mission's twin, washing-machine-sized spacecraft, named Ebb and Flow, entered lunar orbit on New Year's Eve and New Years Day. GRAIL's science phase began yesterday at 8:15 p.m. EST (5:15 p.m. PST). During this mission phase, the spacecraft will transmit radio signals precisely defining the distance between them. As they fly over areas of greater and lesser gravity caused by visible features such as mountains, craters and masses hidden beneath the lunar surface, the distance between the two spacecraft will change slightly. Science activities are expected to conclude on May 29, after GRAIL maps the gravity field of the moon three times. We are in a near-polar, near-circular orbit with an average altitude of about 34 miles (55 kilometers) right now, said David Lehman, GRAIL project manager from NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. During the science phase, our spacecraft will orbit the moon as high as 31 miles (51 kilometers) and as low as 10 miles (16 kilometers). They will get as close to each other as 40 miles (65 kilometers) and as far apart as 140 miles (225 kilometers). Previously named GRAIL A and B, the names Ebb and Flow were the result of a nation-wide student contest to choose new names for the spacecraft. The winning entry was submitted by fourth graders from the Emily Dickinson Elementary School in Bozeman, Mont. Nearly 900 classrooms with more than 11,000 students from 45 states, Puerto Rico and the District of Columbia, participated in the contest. JPL manages the GRAIL mission for NASA's Science Mission Directorate in Washington. The GRAIL mission is part of the Discovery Program managed at NASA's Marshall Space Flight Center in Huntsville, Ala. Lockheed Martin Space Systems in Denver built the spacecraft.

[meteorite-list] Speed that meteors enter dark flight?
Hi All, I have been wondering lately if there have been calculations done on the speeds that meteors stop their hot flight and enter dark flight. What speed does a body have to reach before it generates a hot plasma ball that shows as a fireball...or in other words how fast could a body travel without becoming incandescent. I know this is going to vary depending on altitude or thickness of atmosphere and possibly size. Has anyone seen data that shows this?

Re: [meteorite-list] Speed that meteors enter dark flight?
the follow up to this question/answer I still wonder about is: after dark flight begins, how many seconds will it take to completely decelerate so that all forward momentum is lost after dark flight starts. for example: if the meteor goes dark at 4km/s how many seconds before it will be at 0km/s and/or what does that deceleration curve look like?

[meteorite-list] Sky Tel. article: Mercury's Marvels
Hello All, Speaking of Mercury: I'm sure Pete and some others have already read the article Mercury's Marvels in the April 2012 issue of Sky Tel., pp.26-33. On pp. 28-29, ST senior contributing editor and list member J.K. Beatty describes the three ideas (or notions) of how 'iron-hearted' Mercury formed 4.5 billions years ago. On p. 29, you find a passage that may be a bit confusing, at least I think so: A third notion is that, somehow, Mercury was never Earthlike but instead assembled from metal-rich building blocks. Such bodies exist: metal-rich meteorites called CV chondrites. But what Messenger is seeing on Mercury isn't a good match to those meteorites' composition. An iron-poor type known as aubrite is a better fit (see the box on page 31). It's these words metal-rich meteorites called CV chondrites that may lead to misunderstandings (especially among readers who are not overly familiar with meteorites. A closer look at Allende will show what I mean: The Allende CV3.2 chondrite does have 23.85 % total iron but that should not be mistaken for its FeNi content, which is a mere 0.5% according to a post by Jeff Grossman many years ago. Jeff wrote on Monday, 19 Apr 1999: In fact, Allende has almost no metal, if what you mean is metallic Fe-Ni. Jarosewich (1990) measured ~0.5 wt% metallic iron plus nickel in Allende. Most of the metal in these oxidized CV3 chondrites is the high-Ni alloy awaruite. Another example: The CR2 chondrite Renazzo has 24.93 % total iron but a metal content of only 7.4 wt%.
