Re: [meteorite-list] Rainbow Fusion crust
Rainbow effect on minerals, oil on water, soap bubbles and other examples comes from an optical effect in thin layers. When light is reflected on a surface like a mirror it is reflected equally in every wavelength and you don't get any effect. But if there is a thin layer that some of the light is reflected from then you get interference. If the extra distance travelled is equal to one or more full wavelength of a colour then you get constructive interference and that colour is enhanced. But if the distance travelled is equal to a half plus zero or more full wavelength then you get destructive interference and that colour is dampened. The best example is a drop of oil on water where you could watch the colours change while the oil layer gets thinner. http://en.wikipedia.org/wiki/Thin-film_interference My guess is that the colour seen on these meteorites comes from a thin oxidation layer or maybe from oil from the hands that handled the meteorite. Anyhow, you need a quite glossy surface to get that effect so it is a really fresh meteorite.

To: meteorite-list@meteoritecentral.com Date: Thursday, 21 July, 2011, 0:33 Hi Mike, no worries, neither we understood it like that. Of course, if one looks to the photos, the first idea, which comes to one's mind is: oil. No idea, what causes this effect, maybe the composition. Also that strange tint the cut faces reveal. And especially worrying is the variety of the odd inclusions. I mean normally we all get already excited, whenever we find a carbonaceous fragment in a howardite, but what that stone has all for strange clasts - that is really not normal anymore. Since 1999 Stefan is in Morocco and since then we certainly had quite a bunch of materials in our hands, but such a weird polymict one - extremely unusual. And it seems that many collectors feel the same, if after such a short time now only three slices are left. Now all of the smaller ones are gone, sorry for that. But we have still a slice left, which we could subdivide into small partslices, if desired - but for that one has really to raise his finger. For the moment!

[meteorite-list] NASA'S Next Mars Rover To Land At Gale Crater (MSL)
July 22, 2011 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: 11-243 NASA'S NEXT MARS ROVER TO LAND AT GALE CRATER WASHINGTON -- NASA's next Mars rover will land at the foot of a layered mountain inside the planet's Gale crater. The car-sized Mars Science Laboratory, or Curiosity, is scheduled to launch late this year and land in August 2012. The target crater spans 96 miles (154 kilometers) in diameter and holds a mountain rising higher from the crater floor than Mount Rainier rises above Seattle. Gale is about the combined area of Connecticut and Rhode Island. Layering in the mound suggests it is the surviving remnant of an extensive sequence of deposits. The crater is named for Australian astronomer Walter F. Gale. Mars is firmly in our sights, said NASA Administrator Charles Bolden. Curiosity not only will return a wealth of important science data, but it will serve as a precursor mission for human exploration to the Red Planet. During a prime mission lasting one Martian year -- nearly two Earth years -- researchers will use the rover's tools to study whether the landing region had favorable environmental conditions for supporting microbial life and for preserving clues about whether life ever existed. Scientists identified Gale as their top choice to pursue the ambitious goals of this new rover mission, said Jim Green, director for the Planetary Science Division at NASA Headquarters in Washington. The site offers a visually dramatic landscape and also great potential for significant science findings. In 2006, more than 100 scientists began to consider about 30 potential landing sites during worldwide workshops. Four candidates were selected in 2008. An abundance of targeted images enabled thorough analysis of the safety concerns and scientific attractions of each site. A team of senior NASA science officials then conducted a detailed review and unanimously agreed to move forward with the MSL Science Team's recommendation. The team is comprised of a host of principal and co-investigators on the project. Curiosity is about twice as long and more than five times as heavy as any previous Mars rover. Its 10 science instruments include two for ingesting and analyzing samples of powdered rock that the rover's robotic arm collects. A radioisotope power source will provide heat and electric power to the rover. A rocket-powered sky crane suspending Curiosity on tethers will lower the rover directly to the Martian surface. The portion of the crater where Curiosity will land has an alluvial fan likely formed by water-carried sediments. The layers at the base of the mountain contain clays and sulfates, both known to form in water. One fascination with Gale is that it's a huge crater sitting in a very low-elevation position on Mars, and we all know that water runs downhill, said John Grotzinger, the mission's project scientist at the California Institute of Technology in Pasadena, Calif. In terms of the total vertical profile exposed and the low elevation, Gale offers attractions similar to Mars' famous Valles Marineris, the largest canyon in the solar system. Curiosity will go beyond the follow-the-water strategy of recent Mars exploration. The rover's science payload can identify other ingredients of life, such as the carbon-based building blocks of biology called organic compounds. Long-term preservation of organic compounds requires special conditions. Certain minerals, including some Curiosity may find in the clay and sulfate-rich layers near the bottom of Gale's mountain, are good at latching onto organic compounds and protecting them from oxidation. Gale gives us attractive possibilities for finding organics, but that is still a long shot, said Michael Meyer, lead scientist for NASA's Mars Exploration Program at agency headquarters. What adds to Gale's appeal is that, organics or not, the site holds a diversity of features and layers for investigating changing environmental conditions, some of which could inform a broader understanding of habitability on ancient Mars. The rover and other spacecraft components are being assembled and undergoing final testing. The mission is targeted to launch from Cape Canaveral Air Force Station in Florida between Nov. 25 and Dec. 18. NASA's Jet Propulsion Laboratory in Pasadena manages the mission for the agency's Science Mission Directorate in Washington.

http://www.jpl.nasa.gov/news/news.cfm?release=2011-221 NASA's Dawn Spacecraft Beams Back New Photo Jet Propulsion Laboratory July 21, 2011 [Image} NASA's Dawn spacecraft obtained this image with its framing camera on July 18, 2011. NASA's Dawn spacecraft obtained this image with its framing camera on July 18, 2011. It was taken from a distance of about 6,500 miles (10,500 kilometers) away from the protoplanet Vesta. The smallest detail visible is about 1.2 miles (2.0 km). Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA Dawn took this image during its current orbit of Vesta, traveling from the day side to the night side. The large structure near the south pole that showed up so prominently in previous images is visible in the center of the illuminated surface. Compared to other images, this one shows more of the surface beneath the spacecraft in the shadow of night. Vesta turns on its axis once every five hours and 20 minutes. Dawn entered orbit around Vesta on July 15, 2011, and will spend a year orbiting the body. After that, the next stop on its itinerary will be an encounter with the dwarf planet Ceres. The Dawn mission to Vesta and Ceres is managed by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, for NASA. The University of California, Los Angeles, is responsible for overall Dawn mission science. The Dawn framing cameras have been developed and built under the leadership of the Max Planck Institute for Solar System Research, Katlenburg-Lindau, Germany, with significant contributions by DLR German Aerospace Center, Institute of Planetary Research, Berlin, and in coordination with the Institute of Computer and Communication Network Engineering, Braunschweig. The Framing Camera project is funded by the Max Planck Society, DLR, and NASA/JPL.

[meteorite-list] Mars Rover Opportunity Update: July 14-21, 2011
http://marsrovers.jpl.nasa.gov/mission/status.html#opportunity OPPORTUNITY UPDATE: Opportunity Past 20-Mile Mark As it Nears Large Crater - sols 2656-2662, July 14-21, 2011: Opportunity is only about 1.1 kilometers (0.68 miles) from Spirit Point, the first landfall on the rim of Endeavour crater. The rover continues to make very good progress, driving five times in the last week and totaling over 510 meters of drive distance. The right-front wheel currents remain behaved. The project continues to use backwards driving and actuator heating as mitigation techniques for the elevated drive actuator currents. On Sol 2656 (July 14, 2011), an atmospheric argon measurement was performed with the Alpha Particle X-ray Spectrometer (APXS). On Sol 2662 (July 21, 2011), a visual odometry experiment was performed to measure the precision in which the rover can determine its relative position. This has benefit to future radio tracking experiments with the rover. The plan ahead is more driving. As of Sol 2661 (July 19, 2011), solar array energy production was 417 watt-hours with an atmospheric opacity (Tau) of 0.945 and a solar array dust factor of 0.574. Total odometry is 32,513.36 meters (32.51 kilometers, or 20.20 miles). __ 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] Vesta is NOT a protoplanet
Hi John, Just a gentle request to resist the urge to parrot NASA's erroneous (and mildly self-serving) labeling of Vesta as a protoplanet. Vesta will never evolve into a planet via accretion, so while one might have optimistically called it a protoplanet 4+ billion years ago, that window of opportunity has long since closed. To label it as such is simply an anacronism; it is an asteroid, and nothing more.

Re: [meteorite-list] Is Vesta Mong Nong?
Today's Dawn photo: A lot more little craters visible but still nothing over ~20 mile. What seems to be an ancient 50-mile crater has a fully illuminated vertical side, (not sloped like a crater wall). Disdurbed terrain below the 12-mile-high cliff makes it look like a slump feature. IF Vesta is hard basalt rock, how could it SLUMP? And the illuminated cliff-face is high albedo, burnout white, like ICE. (A spot check shows the actual pixel value is 180 out of 256 grays, a 30% gray, still dam bright for basalt. On the (right) side most fully illuminated, apparent craters with very dark bottoms and albedo rims of no apparent height. Filled with dark lava? Flooded craters as are seen on other bodies? Many gouges revealed on the left, at lower sun-angles, are sinuous, like rilles. More lava flows?. Why no recent-ish craters bigger than 20 miles? I love a mystery. Sterling K.

Abstract This paper reviews the current archaeological and palaeo-environmental evidence from the Younger Dryas period on the Northwest Coast of North America. Sea level histories are region-specific, ranging from 100 m lower to 150 m higher than modern at ca. 12,200 cal BP, the mid-point of the Younger Dryas. Palaeo-environmental evidence shows temperature decrease across the study area, but in some regions this is accompanied by greater precipitation and glacial advance whereas in other conditions were drier. Terrestrial vegetation reflects this variability, with northern areas in particular showing evidence for expansion of herb and shrub tundra and southern areas marked by increased mountain hemlock and other species. Marine, intertidal and terrestrial fauna indicate productive ecosystems, with some sub-regional changes, such as extirpation of deer and bison, perhaps associated with the Younger Dryas onset. Stable isotope analysis of bear remains show these species, which are a good ecological analogue for humans, exploited both marine and terrestrial resources. Despite patchy and dynamic marine and terrestrial environments, these results suggest a challenging, yet viable environment for humans. Archaeological evidence for Younger Dryas human occupation is currently limited to six sites, of which four are associated with karst caves. The earliest of these are in Haida Gwaii, where bear hunting is dated to at least 12,650 cal BP, during the heart of the Younger Dryas interval. Other sites in southeast Alaska and in the Fraser River lowlands date to around 12,100 cal BP. In Puget Sound, the presence of ca. 13,000 cal BP Clovis surface collections, and the emerging data from the pre-Clovis Ayer Pond bison butchery site, suggest pre-Younger Dryas occupation. The Northwest Coast was open to population movement from both the north and south in the poorly known interval before the Younger Dryas, when conditions may have been more moderate and stable. The sub-regional variation and the scale of environmental change in the Younger Dryas, especially sea level fluctuation, makes discovery of Pleistocene archaeological sites challenging. The Younger Dryas may therefore be seen as something of a worst-case scenario for both the human occupation and the archaeological investigation of the Northwest Coast. Article Outline 1.

Abstract Global climate change associated with the onset of the Younger Dryas chronozone affected different regions of the northern hemisphere in different ways. In the Great Basin of western North America, the effect was positive for human populations. Relatively cool temperatures causing effectively wetter conditions filled some pluvial basins with shallow but permanent lakes and other basins with well-watered marshes or meadows. Vegetation communities dominated by sagebrush and grasses promoted healthy and diverse animal populations. Ten archaeological sites from the region have been dated to the Younger Dryas chronozone. Evidence from these sites indicates that Paleoindians with skull shapes and mitochondrial DNA similar to modern western North American Indians occupied the region. These early
Re: [meteorite-list] A sweet PLANETOID by any other name ...
just an asteroid Awww, come guys, VIVA PLANETOID VESTA! ... Remnant protoplanet is perfectly fine description and so what if just an adjective is being dropped! They are not required in the English language unless the context is obviously misunderstood. Agreed that it is a little nutty to think Vesta would dynamically grow into a planet at this point - but that is only one point of view on what a protoplanet is and while a lot of people might insist they know better what a protoplanet is because it sounds like a somewhat scientific term, the definition is just, well, just not there unless someone wants to massage the literature to create an upwelling of passion among scientists that have nothing better to do than carve out new definitions out of what we all have settled already, and then to educate us on our improper usage which they work up in foolish, ramrodded, not properly peer reviewed meetings by all interested parties. To NASA's credit, DAWN's stated mission is to make a trip back to the point in history by hoping Vesta in fact is a remnant protoplanet in the truest form. So in the context of Dawn, while it may serve NASA's publicity, unless someone has an axe to grind against Vesta because of the well-deserved passion and euphoria of all of the growing Vestal crowd that just wants to have a good time, IMO, NASA is well within its bounds. That is not to say that that for every opinion there is not an equal and opposite opinion, but this is not scientific; it is much less scientific at least than the Great Planet Pluto debate garbage many of us got caught up into and that wasn't scientific. Speaking of self serving, if geologists ran the show, there would be no problem calling Vesta a planet even. Astronomers somehow feel that when something is far out in space that somehow makes it their exclusive domain. However, though astronomy is my first true love, IMO it is time to defer to those specializing in planetary geology, especially bodies other than earth. Yeah, I know planetary geologists and astronomers are now just like the delocalized mesomeristic electrons in Kekule benzene diagrams ;-) Right. Pure opinions ... Vesta, however, from a classical view is definitely not just an asteroid. Asteroids are those star-like things that don't move much against the background and are most frequently just points of light on photographic plates and these days in the domain of patient and gifted people like Rob to pick out of noisy backgrounds. Vesta is thought to be actively bombarding earth with fragments and is brighter than planet Uranus at her best. So, just to be a little self serving myself, I'll get ready to announce a new sale of Tatahouine's at great prices, and I think I'll call Vesta a planet. It'd probably be good for marketing, as if no scientist ever marketed his passionate work in the history of the age of reason by selecting the words that suited them! Nah. I love Vesta as a planetoid, but that is just my 2c. Peace, Vesta has just graduated and is on its way to becoming the most studied roundish, formerly volcanic, big object at 2.3 or so AU in the Solar system ... my fingers are crossed that the mission goes well.

Vesta will never evolve into a planet via accretion, so while one might have optimistically called it a protoplanet 4+ billion years ago, that window of opportunity has long since closed. To label it as such is simply an anacronism; it is an asteroid, and nothing more.

Hello List, I don't know what i don't know---so: The latest photo of Vesta shows about 1/2 of this protoplanet which is about 350 miles in diameter and the largest crater looks approximately 1/10 0f this radius which means the crater dia. is about 17.5 miles--quite a hit for such a little guy. I remember seeing a photo of a much smaller asteroid with an impact crater of about 1/3 to 1/2 the size of the whole thing and wonder why it wasn't cracked in half or completely obliterated. So, are impact forces mitigated when an object is not in a tightly bound orbit confiscation and just gets pushed rather than crushed?
