Re: [meteorite-list] From the strewnfield of the newest meteorite fall..........
Hi Rob You are correct about the Montrose fireball. It fragmented very high above the city of Montrose. I have included the text from Chris Peterson's website www.cloudbait.com below. He explains it much better than I could. The fireball began about 25 miles southeast of Montrose at a height of 75 miles, and descended steeply towards the town (47° from the vertical), exploding at a height of 48 miles directly over the southeast corner. This event was captured by the allsky camera at Montrose High School (the orange dot labeled "MHS" is seen very close to the end of the meteor path). From the view of this camera (video, 87K ), the meteor is seen to start high in the sky and rise nearly overhead before exploding, with the final material disappearing behind the camera. This fireball exploded unusually high. Normally, meteoroids are much closer to the ground before the stress of deceleration in the denser atmosphere causes them to break up. The high altitude suggests that the parent body was particularly fragile, possibly cometary debris or a carbonaceous chondrite. This reduces the possibility that material survived to reach the ground. Nevertheless, after a close examination of the decay following the terminal explosion, I think there remains a good possibility that meteorites were formed. Although the path makes it appear that debris would fall over Montrose, the altitude of the breakup combined with high altitude winds that evening make it likely any strewn field produced would actually lie about 12 miles to the northeast, between Montrose and Crawford. My guess is that due to the high winds aloft it flew over Denver 3-4 hours later then again in 24 hours, then againwell you get the "drift". I figure if Mike Farmer and Blaine Reed could not find anything chances are not good that anything will be found.

[meteorite-list] Cassini-Huygens Mission Status Report - May 28, 2004
MEDIA RELATIONS OFFICE JET PROPULSION LABORATORY CALIFORNIA INSTITUTE OF TECHNOLOGY NATIONAL AERONAUTICS AND SPACE ADMINISTRATION PASADENA, CALIF. 91109 TELEPHONE (818) 354-5011 http://www.jpl.nasa.gov Carolina Martinez (818) 354-9382 Jet Propulsion Laboratory, Pasadena, Calif. Donald Savage (202) 358-1727 NASA Headquarters, Washington News Release: 2004-134 May 28, 2004 Cassini-Huygens Mission Status Report The Cassini spacecraft successfully performed a critical six-minute trajectory correction maneuver May 27 to put it on course with its first encounter, Saturn's outermost moon Phoebe, set for June 11. The spacecraft is operating normally and is in excellent health. The maneuver is very critical for getting us into Saturn orbit because it is the first checkout of the bipropellant pressurization system after nearly five years of dormancy, said Todd Barber, propulsion engineer for Cassini at NASA's Jet Propulsion Laboratory, Pasadena, Calif. It sets the stage for Saturn orbit insertion on June 30. During the course of its trip, Cassini has traveled 3.4 billion kilometers (2.1 billion miles). We couldn't have asked for a smoother ride, said Robert T. Mitchell, program manager for the Cassini-Huygens mission at JPL. All the instruments are performing well, and for almost seven years we have traveled without any major hitches. The excitement is building as we are getting ready to put Cassini in orbit around the ringed planet. The orbiter has relied on three radioisotope thermoelectric generators to power all the electrical components, including the 12 science instruments. The European-built Huygens probe on board Cassini carries six instruments. If the road to Saturn were a highway, the Cassini orbiter would have passed the sign along the road that says 'Saturnian County line,' said Jeremy Jones, chief navigator for the Cassini-Huygens mission at JPL. The next exits are Phoebe, 9 million kilometers (5.4 million miles) ahead, Saturn 19 million kilometers (12 million miles) ahead. Phoebe is an oddly shaped moon with a dark surface. It orbits in the opposite direction from the motion of most other bodies in the solar system. The backwards-revolution leads scientists to believe that it is an object captured from distant Kuiper Belt, making it an interesting target. The Phoebe flyby may offer the first glimpse of what the frigid bodies at the edge of the solar system look like, said Dr. Bonnie Buratti, scientist on the Cassini-Huygens mission at JPL. These bodies, which include Pluto and its satellite Charon, are believed to be remnant objects left over from the formation of the planets 4.5 billion years ago. After the Phoebe flyby, Cassini will be on course for Saturn. On arrival date June 30 (July 1 Universal Time), Cassini will become the first orbiter around Saturn. The two Voyager and Pioneer spacecraft flew by the planet and saw it from a distance two or three days at a time. With Cassini, we will be in the city limits for four years, said Dr. Dennis Matson, project scientist for Cassini at JPL. The difference is like driving by the Grand Canyon versus stopping, getting off and enjoying the sights for a while. On arrival, Cassini will begin a 96-minute burn designed to put the spacecraft into Saturn's orbit. As part of getting the spacecraft into orbit, Cassini will twice cross between known gaps in the rings. As a precautionary measure, the spacecraft will use its antenna as a shield to protect it from tiny particle hits. A prime target for Cassini and the piggyback Huygens probe built by the European Space Agency is the smoggy moon Titan. In the 350 years since the discovery of Titan we have come to see it as a world with surprising similarities to our own, yet located almost 1.5 billion kilometers (900 million miles) from the Sun, said Dr. Jonathan Lunine, Huygens interdisciplinary scientist and professor of planetary science and physics at the University of Arizona, Tucson. With a thick, nitrogen-rich atmosphere and possible hydrocarbon seas, Titan may harbor organic compounds important in the chain of chemistry that led to life on Earth. Six months after reaching Saturn, Cassini will release the wok-shaped Huygens probe towards Titan on Dec. 24, 2004 (Dec. 25 Universal Time). The event will be by far the most distant descent of a robotic probe on another object in the solar system. On Jan. 14, 2005 (Jan. 15 Universal Time), Huygens will enter Titan's atmosphere, deploy its parachute, and begin its scientific observations of Titan. 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 Cassini-Huygens mission for NASA's office of Space Science, Washington, D.C. JPL designed, developed and assembled the Cassini orbiter. For the latest images and more

[meteorite-list] Mars Exploration Rover Update - May 27, 2004
http://marsrovers.jpl.nasa.gov/mission/status.html SPIRIT UPDATE: Taking Time to Trench - sol 134-135, May 27, 2004 Spirit roved an impressive 109.5 meters (359.3 feet) on sol 134. Two hours of the drive were guided by the autonomous navigation system. After the long traverse, Spirit completed an hour of post-drive science observations with the panoramic and navigation cameras and mini thermal emission spectrometer. The rover finished the sol healthy and ready for another day on Mars. After so much driving on sol 134, Spirit got a break and spent sol 135 doing in-situ science investigations of its surroundings. It began the sol observing nearby soil with the alpha particle X-ray spectrometer and Moessbauer spectrometer. It then used the microscopic imager to see the soil up close. After stowing the instrument deployment device, Spirit used its wheels to dig a trench and then imaged the trench with the cameras on the mast. Spirit's odometer now reads 2,585.52 meters (1.6 miles). The rover still has 680 meters (0.42 miles) to go before reaching the base of the Columbia Hills, but will likely get there before sol 160. __ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] SAU 001 - L4/5 - S2; W1
Hi list, I was sitting looking at my SAU 001 and I thought it is one of the most beautiful meteorites I have ever seen. Have you ever seen the Hubble deepfield images? They look just the same as a slice of SAU 001. Please let me in on your thoughts ... Lars Pedersen Hello Lars and List, I absolutely concur. When I got my slice from Michael Blood on 13 Jun 2001, I wrote to him: Thank God, the SaU 001 was a real sleeper 'cause it almost knocked my two socks off!!! The description which I wrote that night for my personal collection database will confirm your feelings and thoughts about SaU 001: A thin fully-crusted slice with lots of perfect chondrules of various sizes and colors, and abundant small to medium-sized FeNi specks. The FeNi which surrounds several armored chondrules consists of a minute spray of nickel-iron. One light-colored chondrule measuring 2 mm across, sports a 0.5 mm round FeNi bleb sitting within. The pointed end displays some shock darkened areas where chondrules are less abundant. Have you ever seen the Hubble deep field images? There are some outstanding ones in the July issue of Sky Telescope (pp. 30-31, pp. 42- 49) ... and, yes, they do remind me of the gorgeous, colorful matrix and chondrules of my 16.5-gram SAU 001 slice. I also wrote to Capt'n Blood: Well, this L4/5 is a real 'Sleeping Beauty'. It does look much more like an L3 than an L4/5 and reminds me of Cole Creek. I was so intrigued that I also got a thin section from Michael in August 2001, and, to top it off, I acquired a 340-gram, completely fusion-crusted individual at a local rock and gem show that same month. It has numerous shallow regmaglypts, and is, together with my 194-gram Gao individual from Michael Cottingham, and my 160-gram Allende individual one of the most beautiful pieces that I own.

Re: [meteorite-list] Numbered meteorites
Jeff, I noticed the meteorite that is placed out in the ocean in the Oman map. I saw this a year back when plotting the points and thought it was a simple error. Can you find which meteorite that is and see who found it and why it plots in the ocean? Great job, wonderful work.

[meteorite-list] Deception Point by Dan Brown
Hi All, Don't remember anyone here mentioning Dan Brown's novel, _Deception Point_ (the same Dan Brown who wrote _Angels Demons_ and _The Da Vinci Code_). Meteorites figure prominently in this story, so I thought list members would enjoy reading it. I think Dan has a little bit of confusion over what a chondrule is, but aside from that he spins a good yarn. --Rob __ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list
