Re: [meteorite-list] All impact craters found
Hi Dirk - I don't know bout that particulare hole in the ground. The report does not mention ocean floor craters, nor impact-tsunami chevrons. Here's a few more jokes to brighten your day: Perhaps the story was promoted by Linda Billings, NASA's own very new impact specialist. You may never have heard of her before. I certainly haven't. If anyone here is familiar with her earlier work in impact studies, then please let me know I wouldn't want to not know about them Perhaps she is our anonymous "leading Chinese physicist". It could be that NASA management is afraid that if Don Yeomans is allowed to talk publicly he might bring up that space based neo-detection telescope he requested 10 years ago. As it is, it looks to me from the spin being put on the GAO reports, the G*D D F Mars Nuts want Dr,Morrison to take it over, and are trying to set Don up. It may be that they still have not given up try8ng to get the neo-detection effort assigned somewhere else in the Federal government, such as the NSF. I wonder how they'd feel about Meiser from WISE taking over? Did you ever hear the one about the ASTOEROID that killed the dinosaurs? Or the one how that the only major ASTEROID impact in the last century occurred in 1908 at Tugunska? Or the one about how seldom COMETS or COMET FRAGMENTS hit? Here's a real howler: perhaps the human species is so dumb that a whole lot more people will die before they remember anything. good hunting, everyone E.P.

[meteorite-list] NASA's Curiosity Mars Rover Studies Rock-Layer Contact Zone
http://www.jpl.nasa.gov/news/news.php?feature=4645 NASA's Curiosity Mars Rover Studies Rock-Layer Contact Zone Jet Propulsion Laboratory July 1, 2015 Fast Facts: o Rover team members have resumed commanding Curiosity after a moratorium while the sun was between Earth and Mars. o Curiosity is examing a zone where two regional rock units neighbor each other near "Marias Pass." o The rover found a sandstone with grains of diverse size, shape and color. NASA's Curiosity Mars rover is examining a valley where at least two types of bedrock meet, for clues about changes in ancient environmental conditions recorded by the rock. In addition to two rock types for which this site was chosen, the rover has found a sandstone with grains of differing shapes and color. Curiosity's international team has resumed full operations of the car-size mobile laboratory after a period of limited activity during most of June. The operations moratorium for Curiosity and other spacecraft at Mars happens about every 26 months, when Mars passes nearly behind the sun from Earth's perspective, and the sun interferes with radio communication between the two planets. At the rover's current location near "Marias Pass" on Mount Sharp, Curiosity has found a zone where different types of bedrock neighbor each other. One is pale mudstone, like bedrock the mission examined previously at "Pahump Hills." Another is darker, finely bedded sandstone above the Pahrump-like mudstone. The rover team calls this sandstone the Stimson unit. On Mars as on Earth, each layer of a sedimentary rock tells a story about the environment in which it was formed and modified. Contacts between adjacent layers hold particular interest as sites where changes in environmental conditions may be studied. Some contacts show smooth transitions; others are abrupt. Curiosity climbed an incline of up to 21 degrees in late May to reach Marias Pass, guided by images from NASA's Mars Reconnaissance Orbiter showing Pahrump-like and Stimson outcrops close together. "This site has exactly what we were looking for, and perhaps something extra," said Curiosity Project Scientist Ashwin Vasavada, of NASA's Jet Propulsion Laboratory, Pasadena, California. "Right at the contact between the Pahrump-like mudstone and the Stimson sandstone, there appears to be a thin band of coarser-grained rock that's different from either of them." The in-between material is a sandstone that includes some larger grains, of mixed shapes and colors, compared to the overlying dark sandstone. "The roundedness of some of the grains suggests they traveled long distances, but others are angular, perhaps meaning that they came from close by," Vasavada said. "Some grains are dark, others much lighter, which indicates that their composition varies. The grains are more diverse than in other sandstone we've examined with Curiosity." The science team has identified rock targets for further close-up inspection of the textures and composition of the mudstone and sandstone exposed near Marias Pass. The team ancipates keeping Curiosity busy at this site for several weeks before driving higher on Mount Sharp. Curiosity has been exploring on Mars since 2012. It reached the base of Mount Sharp last year after fruitfully investigating outcrops closer to its landing site and then trekking to the mountain. The main mission objective now is to examine successively higher layers of Mount Sharp. JPL, a division of the California Institute of Technology in Pasadena, built the rover and manages the project for NASA's Science Mission Directorate in Washington.

[meteorite-list] NASA's New Horizons Spacecraft Stays the Course to Pluto
July 01, 2015 RELEASE 15-143 NASA's New Horizons Spacecraft Stays the Course to Pluto NASA's New Horizons spacecraft is getting a final "all clear" as it speeds closer to its historic July 14 flyby of Pluto and the dwarf planet's five moons. After seven weeks of detailed searches for dust clouds, rings, and other potential hazards, the New Horizons team has decided the spacecraft will remain on its original path through the Pluto system instead of making a late course correction to detour around any hazards. Because New Horizons is traveling at 30,800 mph (49,600 kph), a particle as small as a grain of rice could be lethal. "We're breathing a collective sigh of relief knowing that the way appears to be clear," said Jim Green, director of planetary science at NASA. "The science payoff will be richer as we gather data from the optimal flight path, as opposed to having to conduct observations from one of the back-up trajectories." Mission scientists have been using the spacecraft's most powerful telescopic camera, the Long Range Reconnaissance Imager (LORRI), to look for potential hazards, such as small moons, rings, or dust, since mid-May. The decision on whether to keep the spacecraft on its original course or adopt a Safe Haven by Other Trajectory, or "SHBOT" path, had to be made this week since the last opportunity to maneuver New Horizons onto an alternate trajectory is July 4. "Not finding new moons or rings present is a bit of a scientific surprise to most of us," said principal investigator Alan Stern of the Southwest Research Institute (SwRI) in Boulder, Colorado. "But as a result, no engine burn is needed to steer clear of potential hazards. We presented these data to NASA for review and received approval to proceed on course and plan. We are 'go' for the best of our planned Pluto encounter trajectories." New Horizons formed a hazard analysis team in 2011, after the discovery of Pluto's fourth moon, Kerberos, raised concerns the cratering of these moons by small debris from the outer area of the solar system known as the Kuiper Belt, could spread additional hazardous debris into New Horizons' path. Mission engineers re-tested spare spacecraft blanketing and parts back on Earth to determine how well they would stand up to particle impacts, and scientists modeled the likely formation and locations of rings and debris in the Pluto system. By the time New Horizons' cameras were close enough to Pluto to start the search last month, the team had already estimated the chances of a catastrophic incident at far less than one percent. The images used in the latest searches that cleared the mission to stay on its current course were taken June 22, 23 and 26. Pluto and all five of its known moons are visible in the images, but scientists saw no rings, new moons, or hazards of any kind. The hazards team determined that satellites as faint as about 15 times dimmer than Pluto's faintest known moon, Styx, would have been seen if they existed beyond the orbit of Pluto's largest and closest moon, Charon. If any rings do exist, the hazard team determined they must be extremely faint, reflecting less than one 5-millionth of the incoming sunlight. "The suspense - at least most of it - is behind us," says John Spencer, of SwRI, who leads the New Horizons hazard analysis team. "As a scientist I'm a bit disappointed that we didn't spot additional moons to study, but as a New Horizons team member I am much more relieved that we didn't find something that could harm the spacecraft. New Horizons already has six amazing objects to analyze in this incredible system." The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, designed, built, and operates the New Horizons spacecraft, and manages the mission for NASA's Science Mission Directorate. The Southwest Research Institute, based in San Antonio, leads the science team, payload operations and encounter science planning. New Horizons is part of the New Frontiers Program managed by NASA's Marshall Space Flight Center in Huntsville, Alabama.

[meteorite-list] Predictions
Dear Listees, In reading our comments on the past impacts and the propensity for future ones,I cannot ignore the predictions of Nostradamus so beautifully couched in uncorrupted medieval French. Some quatrains that raised my hackles,particularly the timing of FIRE in the SKY events. C.2 Q.46 After great trouble for humanity a greater one is near The Great Motor renews the ages: Rain, blood, milk, famine, steel and plague, In the heavens fire seen, a long spark running. (wow) Apres grat troche humain plus grad s'appreste Le grand moteur les siecles renouuelle Pluye sang laict, famine, fer et peste Au ciel veu feu courant longue estincelle. The fire in the sky is clearly part of this century and is to be part of our current and near-future tribulations. This verse is the epitome of Nostradamus interest in the three great mutations and is far more significant than the events covered in many of Nostradamus' quatrains. Nostradamus specific mention of Meteorites & Asteroids. C.01 Q.46 Very near Auch, Lectoure and Mirande (Predicted postion of constellations known to Nostradamus.) a great fire will fall from the sky for three nights The cause will appear both stupefying and marvellous A short time afterwards the earth will tremble. (Great description of sequence of physical phenomenom.) Tout au pres d'aux de Lestore et Mirande Grand feu du ciel entrois nuicts tumbera Cause aduiendra bien stupende et mirande Bien peu apres la terre tremblera.

[meteorite-list] Giant Meteorite Update
Dear List Members, Many are asking how Team LunarRock's June expedition went, especially the suspected "giant meteorite." We tried to get to the "giant meteorite" site but were mired down in several feet thick mud and other obstacles. We got to within a couple of miles of it but were chased off by intense lightning storms, flash floods, hail and a funnel cloud. I will post images if anybody is interested once I am able to take care of several other pressing issues. We will make another attempt this September if anybody is interested in joining in. We chose June on this attempt because it was supposed to be the driest month of the year. Unfortunately, no amount of planning can take into account bad weather. There is nothing more disappointing than observing massive and pristine "dry" lake beds that are wet. We did successfully make it to three other sites but were mostly unproductive, as far as meteorites go, but did recover some rarities and other real treasure that made the undertaking worthwhile. I will provide a field report once I am caught up. I consider this 1,700 mile expedition a success based on both excitement and adventure, not to mention the acquisition of some real treasure.
