[meteorite-list] Gold Basin Group Outing
This past weekend (Nov. 8-10th) my father and I drove up to Gold Basin, AZ for the Nuggetshooter.com group outing. It's pretty hard to find meteorites at GB anymore so I was surprised at our finds. Below is a link to my Flickr album containing photos from the hunt: https://www.flickr.com/photos/fislermeteorites/sets/72157648876507848/ If anyone is interesting in viewing other photos from our hunts over the years, below is a link to my entire Flickr photo-stream: https://www.flickr.com/fislermeteorites Erik Fisler phx.e.f...@gmail.com __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list

[meteorite-list] Newly Released Map Data Shows Frequency of Small Asteroid Impacts, Provides Clues on Larger Asteroid Population
http://neo.jpl.nasa.gov/news/news186.html Newly Released Map Data Shows Frequency of Small Asteroid Impacts, Provides Clues on Larger Asteroid Population Linda Billings NASA/JPL Near-Earth Object Program Office November 14, 2014 It happens all the time: small asteroids impact Earth's atmosphere Small asteroids near Earth, with sizes of only about a meter, hit the atmosphere and disintegrate with surprising frequency - around every other week, new data show. Data gathered by U.S. government sensors and released to NASA for use by the science community reveal that these small impact events are frequent and random. A map of these small impact events - known as fireballs or bolides - recently released by NASA shows the frequency and approximate energy released by bolide events detected from 1994 through 2013. It dwarfs a data-base of small impacts based on infra-sound detections released last fall, but it does not contain all fireballs - objects less than a meter in size - that impacted the Earth during this period. [Graphic] Map showing the bolide events from 1994 to 2013 Over this 20-year interval, U.S. Government assets recorded at least 556 bolide events of various energies. On this world map illustration, the size of the orange dots (daytime events) and blue dots (nighttime events) are proportional to the optical radiated energy of the impact event measured in billions of Joules (GJ) of energy. An approximate conversion between the measured optical radiant energy and the total impact energy can be made using an empirical relationship provided by Peter Brown and colleagues in 2002. For example the smallest dot on the map represents 1 billion Joules (1 GJ) of optical radiant energy, or when expressed in terms of a total impact energy the equivalent of about 5 tons of TNT explosives. Likewise, the dots representing 100, 10,000 and 1,000,000 Giga Joules of optical radiant energies correspond to impact energies of about 300 tons, 18,000 tons and one million tons of TNT explosives respectively. The largest impact energy recorded during this 20-year interval was the recent daytime Chelyabinsk event (440,000 - 500,000 tons of TNT) recorded over central Russia on February 15, 2013. This small asteroid that exploded in the atmosphere near Chelyabinsk, Russia was about 20 meters in size before it hit the Earth. While that impact focused public attention on the potential hazards of NEO impacts with Earth, space scientists have long known that such events are just a part of Earth's geologic history. NASA's Near Earth Object (NEO) Observations Program finds, tracks, and characterizes asteroids whose orbits bring them within approximately 50 million kilometers (31 million miles) of Earth's orbit about the sun. We now know that Earth's atmosphere does a great job of protecting Earth from small asteroids, said NASA NEO Observations Program Executive Lindley Johnson. The new data will be extrapolated to estimate more precisely the frequency of impacts by asteroids large enough to cause ground damage. How big is the population of larger asteroids we really need to worry about? We need to better understand that. Johnson said. While the new data emphasize that small asteroid impacts with Earth are not unusual, the risk of future impacts is not to be taken lightly. The aim is to find potentially hazardous asteroids before they find us, said Donald Yeomans, manager of NASA's NEO Program Office at the Jet Propulsion Laboratory. NASA's Asteroid Initiative features a Grand Challenge to the community to create a plan to find all asteroid threats to human populations and know what to do about them. The NEO Observations Program already has identified more than 96 percent of the estimated population of nearly one thousand one-kilometer or larger sized asteroids. The Program's current objective is to identify 90 percent or more of the far more numerous NEOs larger than 140-meters in diameter. It is estimated they may be as much as 25 times more numerous than 1 kilometer asteroids. Every day, Earth is bombarded with more than 100 tons of dust and sand-sized particles from space. About once a year, an automobile-sized asteroid hits Earth's atmosphere, creating a spectacular fireball (bolide) event as the friction of the Earth's atmosphere causes them to disintegrate - sometimes explosively. Studies of Earth's history indicate that about once every 5,000 years or so on average an object the size of a football field hits Earth and causes significant damage. Once every few million years on average an object large enough to cause regional or global disaster impacts Earth. Impact craters on Earth, the Moon and other planetary bodies are evidence of these occurrences. Meteor Crater near Winslow, Arizona, is evidence of the impact with Earth's surface of a 50-meter asteroid about 50,000 years ago. Impact of the metal-rich object released energy equivalent to a 10
