[meteorite-list] Odd Rock - Is it...??
Dear list, this is a first time posting, so please be patient with me as I still need to get the hang of recognizing the physical properties of meteorites that don't have fresh baked crusts or bright olivine and chondrules. http://www.geocities.com/sstelenes/rocks.html The above link is a page with three photos and a description of an odd "stone" from Mexico. I don't think it is a meteorite. (I have found some others I suspect to be, though.) This particular one was given to me and the giver (finder) insisted it was a meteorite. I don't think so, but it is certainly odd, does anyone know what it could be, with all these odd gunmetal gray square shapes? Thanks. Doug Dawn Mexico

Doug, I think everyone will have fun with this. My guess is that its a batch of parts that were throw out the back door of a plating shop around 35 years ago. Bill Kieskowski __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

*SNOE satellite to re-enter atmosphere in coming days* *UNIVERSITY OF COLORADO-BOULDER NEWS RELEASE* Posted: December 2, 2003 A $5 million University of Colorado at Boulder satellite dubbed the Little Satellite That Did now is expected to re-enter the atmosphere and burn up in early December following a successful six-year mission. The Student Nitric Oxide Explorer, or SNOE, is carrying instruments that have measured nitric oxide in the upper atmosphere that affects Earth's ozone layer, the intensity of X-rays from the sun and ultraviolet light from Earth's aurora. Developed at CU-Boulder's Laboratory for Atmospheric and Space Physics by students, engineers and faculty, the mission has been controlled from LASP's CU Research Park facility 24 hours a day by students and faculty since early 1998. http://spaceflightnow.com/news/n0312/02snoe/ __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] STARDUST Update - December 5, 2003
Stardust Status Report December 5, 2003 The Stardust team has had daily communications with the spacecraft in the past week. Telemetry relayed from the spacecraft indicates it remains in very good shape as it approaches its date with Comet Wild 2 on January 2, 2004. Trajectory Correction Maneuver 10 was successfully executed on December 3. The burn duration was 118 seconds. This trajectory correction maneuver places Startdust on a trajectory that is a little inside the 300 kilometer flyby distance planned for Comet Wild 2. Three more trajectory correction maneuvers are planned during the next month to precisely control the flyby to 300 km +/- 50 km. On December 4, the seventh and last of the bi-weekly optical navigation images was taken. Daily optical navigation imaging begins on Monday, December 8th. A JPL news release of NASA Spacecraft Pinpoints Where the Wild Thing Is was issued on December 1 which as picked up by other news organziations. An article was published in the Los Angeles Times in the Kid's Corner section on November 26 titled Giant Snowballs in Outer Space! (They're Actually Comets). The Stardust mission was highlighted on Los Angeles KKJC 88.1 Jazz Radio on December 2. Space Place created an online Stardust activity called Tails of Wonder which is available here: http://spacespace.jpl.nasa.gov/stardust Information on the present position and orbits of the Stardust spacecraft and comet Wild 2 may be found on the Where Is Stardust Right Now? web page located at: http://stardust.jpl.nasa.gov/mission/scnow.html For more information on the Stardust mission -- the first ever comet sample-return mission -- please visit the Stardust home page: http://stardust.jpl.nasa.gov . __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] NASA Scientists Use Radar to Detect Asteroid Force
MEDIA RELATIONS OFFICE JET PROPULSION LABORATORY CALIFORNIA INSTITUTE OF TECHNOLOGY NATIONAL AERONAUTICS AND SPACE ADMINISTRATION PASADENA, CALIFORNIA 91109. TELEPHONE (818) 354-5011 http://www.jpl.nasa.gov D.C. Agle (818) 393-9011 Jet Propulsion Laboratory, Pasadena, Calif. December 5, 2003 NEWS RELEASE: 2003-163 NASA Scientists Use Radar to Detect Asteroid Force NASA scientists have for the first time detected a tiny but theoretically important force acting on asteroids by measuring an extremely subtle change in a near-Earth asteroid's orbital path. This force, called the Yarkovsky Effect, is produced by the way an asteroid absorbs energy from the sun and re-radiates it into space as heat. The research will impact how scientists understand and track asteroids in the future. Asteroid 6489 Golevka is relatively inconspicuous by near-Earth asteroid standards. It is only one half-kilometer (.33 mile) across, although it weighs in at about 210 billion kilograms (460 billion pounds). But as unremarkable as Golevka is on a celestial scale it is also relatively well characterized, having been observed via radar in 1991, 1995, 1999 and this past May. An international team of astronomers, including researchers from NASA's Jet Propulsion Laboratory in Pasadena, Calif., have used this comprehensive data set to make a detailed analysis of the asteroid's orbital path. The team's report appears in the December 5 issue of Science. For the first time we have proven that asteroids can literally propel themselves through space, albeit very slowly, said Dr. Steven Chesley, a scientist at NASA's Jet Propulsion Laboratory and leader of the study. The idea behind the Yarkovsky Effect is the simple notion that an asteroid's surface is heated by the sun during the day and then cools off during the night. Because of this the asteroid tends to emit more heat from its afternoon side, just as the evening twilight on Earth is warmer than the morning twilight. This unbalanced thermal radiation produces a tiny acceleration that has until now gone unmeasured. The amount of force exerted by the Yarkovsky Effect, about an ounce in the case of Golevka, is incredibly small, especially considering the asteroid's overall mass, said Chesley. But over the 12 years that Golevka has been observed, that small force has caused a shift of 15 kilometers (9.4 miles). Apply that same force over tens of millions of years and it can have a huge effect on an asteroid's orbit. Asteroids that orbit the Sun between Mars and Jupiter can actually become near-Earth asteroids. The Yarkovsky Effect has become an essential tool for understanding several aspects of asteroid dynamics. Theoreticians have used it to explain such phenomena as the rate of asteroid transport from the main belt to the inner solar system, the ages of meteorite samples, and the characteristics of so-called asteroid families that are formed when a larger asteroid is disrupted by collision. And yet, despite its profound theoretical significance, the force has never been detected, much less measured, for any asteroid until now. Once a near-Earth asteroid is discovered, radar is the most powerful astronomical technique for measuring its physical characteristics and determining its exact orbit, said Dr. Steven Ostro, a JPL scientist and a contributor to the paper. To give you an idea of just how powerful - our radar observation was like pinpointing to within a half inch the distance of a basketball in New York using a softball-sized radar dish in Los Angeles. To obtain their landmark findings, the scientists utilized an advanced model of the Yarkovsky Effect developed by Dr. David Vokrouhlický of Charles University, Prague. Vokrouhlický led a 2000 study that predicted the possibility of detecting the subtle force acting on Golevka during its 2003 approach to Earth. We predicted that the acceleration should be detectable, but we were not at all certain how strong it would be, said Vokrouhlický. With the radar data we have been able to answer that question. Using the measurement of the Yarkovsky acceleration the team has for the first time determined the mass and density of a small solitary asteroid using ground-based observations. This opens up a whole new avenue of study for near-Earth asteroids, and it is only a matter of time before many more asteroids are weighed in this manner. In addition to Chesley, Ostro and Vokrouhlický, authors of the report include Jon Giorgini, Dr. Alan Chamberlin and Dr. Lance Brenner of JPL; David Capek, Charles University, Prague, Dr. Michael Nolan, Arecibo Observatory, Puerto Rico, Dr. Jean-Luc Margot, University of California, Los Angeles, and Alice Hine, Arecibo Observatory, Puerto Rico. Arecibo Observatory is operated by Cornell University under a cooperative agreement with the National Science Foundation and with support from NASA.

[meteorite-list] Mars Odyssey THEMIS Images - December 1-4, 2003
MARS ODYSSEY THEMIS IMAGES December 1-4, 2003 o Swirling Winds Reflected In Dunes (Released 1 December 2003) http://themis.la.asu.edu/zoom-20031201a.html These dark transverse and linear dunes are located in the floor of a crater in the southern highlands. The dunes appear to follow the flow of winds that circle around the crater floor, creating a swirling pattern. Rather than swirling winds, however, the apparent arc may simply be caused by a north to south shift in the relative strengths of two winds that influence these dunes. o Disappearing Act (Released 2 December 2003) http://themis.la.asu.edu/zoom-20031202a.html o Nili Fossae in Color (Released 3 December 2003) http://themis.la.asu.edu/zoom-20031203a.html o Hematite Outlier and Sand Dunes (Released 4 December 2003) http://themis.la.asu.edu/zoom-20031204a.html This image shows a crater just south of the edge of the famous hematite-bearing surface, which is visible in the context image as a smooth area to the north. The crater has two features of immediate note. The first is a layered mound in the north part of the crater floor. This mound contains hematite, and it is an outlying remnant of the greater deposits to the north that have otherwise completely disappeared in this crater. The second feature is a dune field in the center of the crater floor, with dark dunes indicating winds from the northwest. The dunes grade into a dark sand sheet with no coherent structure, indicating that the sand layer thins out to the south and east. All of the THEMIS images are archived here: http://themis.la.asu.edu/latest.html NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C.

[meteorite-list] Classic meteorites - my Top 10
Hello all, On a quiet snowy night here in Pennsylvania I had a thought about classic meteorites. My first question was...what is a classic meteorite? Lots of answers I'm sure to that...but I came up with my own simple set of Rules. Popular, nice material, in lots of collections, stays in good condition, rich history, can be acquired if desired, should stay a favorite, etc. Here is my own list and ranking. Top 10 Classic Meteorites 1. Sikhote-Alin: an iron from a Russian fall in 1947 2. Canyon Diablo: an iron found near Meteor Crater, USA 3. Allende: a carbonaceous chondrite fall in Mexico in 1969 4. Gibeon: an iron found in Africa 5. Gao: a stone from a 1960 fall in Burkino Faso 6. Murchison: an awesome carbonaceous fall in Australia in 1969 7. Esquel: a pallasite type stony-iron found in South America 8. Zagami: a 1962 Martian fall in Nigeria, Africa 9. Henbury: an iron found in Australia 10. Vaca Muerta: a mesosiderite type stony-iron found in South America Try your own list on us... putting Gao at #5 is probably too high with my list.

That site with the bogus meteorite has more bogus baggage.

You will need spybot or similar to remove it.
