[meteorite-list] Hartley meteor?
On 25 October 20:01 CDT I was standing in my central Texas backyard when a bright light passed overhead in a NNE direction. We were socked in with a thin low haze that completely obliterated the stars but this light was bright enough to track through the low ceiling. This object moved at a speed comparable to space junk that is burning in- quite slow for a meteor, but it gave me pause to consider what it might have been. So now I wonder if Hartley was responsible.

[meteorite-list] NASA Trapped Mars Rover Finds Evidence of Subsurface Water
Oct. 28, 2010 Dwayne Brown Headquarters, Washington 202-358-1726 dwayne.c.br...@nasa.gov Guy Webster Jet Propulsion Laboratory, Pasadena, Calif. 818-354-6278 guy.webs...@jpl.nasa.gov RELEASE: 10-278 NASA TRAPPED MARS ROVER FINDS EVIDENCE OF SUBSURFACE WATER PASADENA, Calif. -- The ground where NASA's Mars Exploration Rover Spirit became stuck last year holds evidence that water, perhaps as snow melt, trickled into the subsurface fairly recently and on a continuing basis. Stratified soil layers with different compositions close to the surface led the rover science team to propose that thin films of water may have entered the ground from frost or snow. The seepage could have happened during cyclical climate changes during periods when Mars tilted farther on its axis. The water may have moved down into the sand, carrying soluble minerals deeper than less-soluble ones. Spin-axis tilt varies over timescales of hundreds of thousands of years. The relatively insoluble minerals near the surface include what is thought to be hematite, silica and gypsum. Ferric sulfates, which are more soluble, appear to have been dissolved and carried down by water. None of these minerals is exposed at the surface, which is covered by wind-blown sand and dust. The lack of exposures at the surface indicates the preferential dissolution of ferric sulfates must be a relatively recent and ongoing process since wind has been systematically stripping soil and altering landscapes in the region Spirit has been examining, said Ray Arvidson of Washington University in St. Louis, deputy principal investigator for the twin rovers Spirit and Opportunity. Analysis of these findings appears in a report in the Journal of Geophysical Research published by Arvidson and 36 co-authors about Spirit's operations from late 2007 until just before the rover stopped communicating in March. The twin Mars rovers finished their three-month prime missions in April 2004, then kept exploring in bonus missions. One of Spirit's six wheels quit working in 2006. In April 2009, Spirit's left wheels broke through a crust at a site called Troy and churned into soft sand. A second wheel stopped working seven months later. Spirit could not obtain a position slanting its solar panels toward the sun for the winter, as it had for previous winters. Engineers anticipated it would enter a low-power, silent hibernation mode, and the rover stopped communicating March 22. Spring begins next month at Spirit's site, and NASA is using the Deep Space Network and the Mars Odyssey orbiter to listen if the rover reawakens. Researchers took advantage of Spirit's months at Troy last year to examine in great detail soil layers the wheels had exposed, and also neighboring surfaces. Spirit made 13 inches of progress in its last 10 backward drives before energy levels fell too low for further driving in February. Those drives exposed a new area of soil for possible examination if Spirit does awaken and its robotic arm is still usable. With insufficient solar energy during the winter, Spirit goes into a deep-sleep hibernation mode where all rover systems are turned off, including the radio and survival heaters, said John Callas, project manager for Spirit and Opportunity at NASA's Jet Propulsion Laboratory, in Pasadena, Calif. All available solar array energy goes into charging the batteries and keeping the mission clock running. The rover is expected to have experienced temperatures colder than it has ever before, and it may not survive. If Spirit does get back to work, the top priority is a multi-month study that can be done without driving the rover. The study would measure the rotation of Mars through the Doppler signature of the stationary rover's radio signal with enough precision to gain new information about the planet's core. The rover Opportunity has been making steady progress toward a large crater, Endeavour, which is now approximately 5 miles away. Spirit, Opportunity, and other NASA Mars missions have found evidence of wet Martian environments billions of years ago that were possibly favorable for life. The Phoenix Mars Lander in 2008 and observations by orbiters since 2002 have identified buried layers of water ice at high and middle latitudes and frozen water in polar ice caps. These newest Spirit findings contribute to an accumulating set of clues that Mars may still have small amounts of liquid water at some periods during ongoing climate cycles.

[meteorite-list] EPOXI Spacecraft Preps for Comet Flyby
http://www.jpl.nasa.gov/news/news.cfm?release=2010-353 NASA Spacecraft Preps for Comet Flyby Jet Propulsion Laboratory October 27, 2010 In one of its final mission trajectory correction maneuvers, the EPOXI mission spacecraft has refined its orbit, preparing it for the flyby of comet Hartley 2 on Nov. 4. The time of closest approach to the comet on that day is expected to be about 7:02 a.m. PDT (10:02 a.m. EDT). Today's trajectory correction maneuver began at 11 a.m. PDT (2 p.m. EDT), when the spacecraft burned its engines for 60 seconds, changing its velocity by 1.59 meters per second (3.6 miles per hour). On Nov. 4, the spacecraft will fly past Hartley 2 at a distance of about 700 kilometers (435 miles). It will be only the fifth time in history that a spacecraft has been close enough to image a comet's nucleus. EPOXI is an extended mission that uses the already in-flight Deep Impact spacecraft to explore distinct celestial targets of opportunity. The name EPOXI itself is a combination of the names for the two extended mission components: the extrasolar planet observations, called Extrasolar Planet Observations and Characterization (EPOCh); and the flyby of comet Hartley 2, called the Deep Impact Extended Investigation (DIXI). The spacecraft will continue to be referred to as Deep Impact. NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the EPOXI mission for NASA's Science Mission Directorate, Washington. The University of Maryland, College Park, is home to the mission's principal investigator, Michael A'Hearn. Drake Deming of NASA's Goddard Space Flight Center, Greenbelt, Md., is the science lead for the mission's extrasolar planet observations. The spacecraft was built for NASA by Ball Aerospace Technologies Corp., Boulder, Colo. For more information about EPOXI, visit: http://epoxi.umd.edu/ .

[meteorite-list] update on all my finds from NV.
Hi All, I had the great pleasure of having one of the top meteorite hunters in the USA stop in here to visit at my camp at El Mirage. HE and his incredibly nice lady friend both had a really nice long visit with me and my wife, Terri. I don't want to name any names here but he took his time out of his day to look over all of my NV dry lake bed finds from last summer and fall of hunting. I just can't express what a pleasure it was spending time with both of them. They are true treasures both of them. Any way I have two of my finds that were in my Meteorite pile from Jungo that have to go back into my meteor wrong pile. The first one was one that I had in my wrong pile but moved over into my finds pile. It was not magnetic at all but had all of the looks of a meteorite. So he goes back as a wrong now again. Now my number two wrong was, the smaller Jungo that was heavily magnetic and at one end had what I thought to be large olivine crystal gold . Well they are not, I believe he said quartz crystals and pyrite. So this little fella goes back into the wrong pile. And it looks like the rusty orange colored Luning rock will go back to my wrong pile as well . But when I get a new saw blade I will open him up for a better look inside During the big rains here I had my Jungo meteor wrongs out side and in the rain for a few days. So some days back I looked them over again after the playa was washed off them nicely. I found what looked to be a new find in my jungo wrong pile. I opened up a window and there it was nice light nickel flakes. After it was looked at by a pro I was able to add it to my Jungo Meteorite pile that will be sent in for testing. Then on my 3 bigger NE NV finds that I got underground on a dry lake bed near a big strune field where I recovered about 200 fragments at Sonny's strune field. Well there is a very good chance that these are from a different meteorite fall then the ones from the strune field. After they get classified I will up date you all. Here is my goodies I will send in I got 3 bigger ones from NE NV underground that are lightly magnetic 1 bigger one from Tungston . the other 6 smaller ones will not be sent in. 3 really nice ones from Jungo I will have thin sections made and sent in for classification ASAP. The ebb and flow of wrongs to rights and rights to wrongs. So, I am now down 2 meteorite from what I had a few days back. Its all part of the fun of meteorite recovery. WE are now headed back into the field at my no name location in the middle of the Mojave for two more weeks of Joyous meteorite recovery Best Regards Scott Johnson U.S. AirBorne Sport Aviation LLC Eagles Nest Airpark Sport Pilot C.F.I WSC-L WSC-S www.usairborne.com i...@usairborne.com Office 509-780-0554 Cell 509-780-8377 __ 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

[meteorite-list] Sun Eruption and Close Earth Flyby of Asteroid 2003 UV11
Space Weather News for Oct. 28, 2010 http://spaceweather.com SUN TWISTER: Earlier today, NASA's Solar Dynamics Observatory (SDO) recorded a spectacular eruption on the sun's northeastern limb. An unstable magnetic filament hundreds of thousands of kilometers long pirouetted and launched a fragment of itself into space. Earth was not in the line of fire, but the SDO movie is worth seeing anyway. Visit http://spaceweather.com for cinema. ASTEROID FLYBY: Asteroid 2003 UV11 will fly past Earth on Oct. 29th and 30th at a distance of only 1.2 million miles. Experienced amateur astronomers should have little trouble photographing the 600-meter wide space rock as it glides through the constellation Pegasus on Friday night, glowing about as brightly as a 12th magnitude star. Observers in North America and Europe are favored.

[meteorite-list] Where Is the New Horizons Centaur Stage?
http://pluto.jhuapl.edu/news_center/news/20101028.php Where Is the New Horizons Centaur Stage? Alan Stern and Yanping Guo October 28, 2010 When New Horizons launched at 2 p.m. Eastern time on January 19, 2006, its first Atlas V stage and solid rocket boosters fell back to Earth within minutes of launch, never entering orbit. New Horizons then proceeded on to Earth orbit aboard its Atlas V's powerful Centaur second stage, which then re-ignited to propel itself, New Horizons and its STAR-48 third-stage solid rocket out of Earth orbit. Just seconds after the Centaur stage completed that Earth-escape maneuver, it was discarded, and New Horizons was propelled onto its Pluto trajectory by a brief (84-second) but powerful (up to 13 G!) burn of its third stage. That derelict third stage is now traveling out of the solar system in the general direction of Pluto, much like New Horizons, though it will miss Pluto by hundreds of millions of miles because it has no ability to make the course corrections to precisely target for Pluto as New Horizons itself has. But what became of the also now derelict Centaur second stage New Horizons left behind? It's orbiting between the Earth and the asteroid belt, with a period of 2.83 years, never reaching farther than three times as far from the Sun as the Earth does. Orbital calculations reveal that the approximate current positions of New Horizons, its STAR-48 third stage, and its Centaur second stage are as shown in the figure below. The Centaur stage is now on its second orbit of the Sun, having just passed its aphelion, or greatest distance from the Sun, and is now approaching the orbit of Mars as it falls back sunward.

[meteorite-list] UNT confirms man’s meteorite
Seems like they could have done more testing. Seems a little off. Greg S. http://www.dentonrc.com/sharedcontent/dws/drc/localnews/stories/DRC_meteor_1028.1d2463a9b.html UNT confirms man’s meteorite Down to Earth 11:58 PM CDT on Wednesday, October 27, 2010 By Rachel Mehlhaff / Staff Writer A man recently found out that a rock he stumbled upon two years ago is actually a meteorite. George Wright holds a meteorite he discovered near Lufkin, on Wednesday in Denton. Researchers at the University of North Texas confirmed that Wright’s find was from a meteor. George Wright of Denton was walking outside his brother’s house in Lufkin when he kicked a rock that was sticking out of the ground. He knew it wasn’t like rocks that are typically found in the area, he said, because he hauled rocks for 30 years. “I could tell it was different,” he said of the rock that was halfway buried in the clay. Wright’s girlfriend convinced him to take the rock, which sat on a shelf at his parents’ house for the past couple of years, to the University of North Texas. “I had an idea it was a meteorite,” Wright said. His suspicions were confirmed with the help of George Maxey and Ron DiIulio, UNT faculty members who put Wright’s rock to the meteorite test. A meteoroid is the result of two asteroids colliding in space, DiIulio said. DiIulio said an asteroid has three layers: the core, which is made of iron; the middle “boundary” layer, which is a combination of stone and iron; and the outer “mantle” layer, which is made of stone. Each layer produces different types of meteorites that people find. “Ninety-four percent of the meteorites that come in are rock,” he said. He said 5 percent are iron and 1 percent of meteorites are stony iron. Since the meteorite was found in Texas by a Denton resident, the university wanted to keep the meteorite in Denton, and UNT was willing to pay Wright $300 for his find. But there is no easy answer to how much a meteorite is worth, as each type has a different monetary value, DiIulio said, adding that each part of an asteroid is important to scientific research. He said a person has to research the market. An iron meteorite, like the one weighing 300 grams that Wright found, is worth $1 per gram. “Unless you find one of these oddballs like this,” said DiIulio, pointing to a stony iron meteorite — worth closer to $50 per gram. The stone meteorites are worth about 15 to 20 cents a gram. To determine whether Wright’s rock was a meteorite, it went through several tests, starting with a test to see if it was attracted to magnets. DiIulio said that even stone meteorites are usually attracted to magnets. Researchers also check that it is solid and not porous, and that it is an irregular shape, Maxey said. Meteorites usually don’t have sharp edges, and they have what look like “thumb prints,” DiIulio said, which researchers believe form when a meteorite enters the Earth’s atmosphere and burns unevenly. They don’t know the composition of Wright’s meteorite yet, he said. And it is difficult to date the meteor that Wright’s rock came from, but DiIulio said he believes that the meteorite is from a meteor that fell in 1955 and was reported in the Port Arthur News. DiIulio and Maxey are hoping to extract Earth rocks from the meteorite that will help them determine when it may have fallen. “Earth rock may be easier for us to date,” DiIulio said. He said that while they may not know whether it fell in 1955, he thinks the coincidence is significant. This year UNT opened a lab that allows people to do just what Wright did — bring in their finds and determine if they have meteorites or fossils. “We have a lot of people come in with objects; they don’t know what they are,” Maxey said. Many people bring in what DiIulio calls “meteor-wrongs,” as opposed to meteorites. He has a collection of those items on a table in his office for comparison with possible meteorites. He and Maxey encourage people to bring in objects they want tested.

[meteorite-list] Achondrite - looking for experts!
Hello meteorite friends, Two years ago I bought in Dean Bessey's shop an unclassified NWA. THe side which I have polished now was very bad weathered and it took a long time and hard work until I finished it. Because there was last week a discussion about achondrites, I hope to find now experts who can tell me whether the piece is an achondrite or not and what kind it is. The total surface (about 6 x 4 inches) show no chondrules but a lot of iron flake nests. Remarkable are only the two pyroxene xenolithes. Comparing to my collection the surface looks like a Shisr 007 urelite. Photos are stored under http://s345.photobucket.com/albums/p384/m42protosun/?action=viewcurrent=achondrite3.jpgnewest=1 Is anyone able to give an expert opinion?

[meteorite-list] Thin Section / Micro-photography Update.
I'll like to start off by thanking those of you who have offered assistance to me while I was setting up my microscope and working out the kinks. I'd also like to apologize for that funky looking SRPoD recently. Privately, Anne Black made a polite comment about the focus. I agreed about the problems but commented back that's about as good as it gets. Her comment bothered me enough to make look deeper into my setup and I found a few things that weren't quite right and were causing severe distortions. Needless to say I've resolved the easiest ones, which were causing the worst effects. The event also motivated me to put in a foundation of basic pages for my microphotography, both thin sections and biologic specimens online, so I have a little more control over them than I do on other sites. The pages will never be polished. You can access my new and improved meteorite thin section photography at: http://www.lpl.arizona.edu/~kowalski/microscopy/meteorite_thin_sections.htm I currently have 9 Pena Blanca Spring images up and 7 of the R4, NWA 5426 Partly because I'm still working out bugs in my setup and I want to really see the errors that are left, many of my images are processed to bring out the maximum detail. You may not like the way those images are processed. I also have some that are adjusted for aesthetic reasons and may not be scientifically accurate. Note that the full res images are between 2 and 4 meg in size each, so once you click on the link to the image, be patient if you have a slow connection. I'd be interested in hearing from experienced microscopists who have suggestions on ways to resolve the optical aberrations. The other areas of the microscopy section are live, mostly incomplete, but might be useful or interesting to others. Thanks for taking the time to look. -- Richard Kowalski __ 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
