[meteorite-list] Asteroid 1998 QE2 to Sail Past Earth Nine Times Larger Than Cruise Ship
http://www.jpl.nasa.gov/news/news.php?release=2013-163 Asteroid 1998 QE2 to Sail Past Earth Nine Times Larger Than Cruise Ship Jet Propulsion Laboratory May 15, 2013 On May 31, 2013, asteroid 1998 QE2 will sail serenely past Earth, getting no closer than about 3.6 million miles (5.8 million kilometers), or about 15 times the distance between Earth and the moon. And while QE2 is not of much interest to those astronomers and scientists on the lookout for hazardous asteroids, it is of interest to those who dabble in radar astronomy and have a 230-foot (70-meter) -- or larger -- radar telescope at their disposal. Asteroid 1998 QE2 will be an outstanding radar imaging target at Goldstone and Arecibo and we expect to obtain a series of high-resolution images that could reveal a wealth of surface features, said radar astronomer Lance Benner, the principal investigator for the Goldstone radar observations from NASA's Jet Propulsion Laboratory in Pasadena, Calif. Whenever an asteroid approaches this closely, it provides an important scientific opportunity to study it in detail to understand its size, shape, rotation, surface features, and what they can tell us about its origin. We will also use new radar measurements of the asteroid's distance and velocity to improve our calculation of its orbit and compute its motion farther into the future than we could otherwise. The closest approach of the asteroid occurs on May 31 at 1:59 p.m. Pacific (4:59 p.m. Eastern / 20:59 UTC). This is the closest approach the asteroid will make to Earth for at least the next two centuries. Asteroid 1998 QE2 was discovered on Aug. 19, 1998, by the Massachusetts Institute of Technology Lincoln Near Earth Asteroid Research (LINEAR) program near Socorro, New Mexico. The asteroid, which is believed to be about 1.7 miles (2.7 kilometers) or nine Queen Elizabeth 2 ship-lengths in size, is not named after that 12-decked, transatlantic-crossing flagship for the Cunard Line. Instead, the name is assigned by the NASA-supported Minor Planet Center in Cambridge, Mass., which gives each newly discovered asteroid a provisional designation starting with the year of first detection, along with an alphanumeric code indicating the half-month it was discovered, and the sequence within that half-month. Radar images from the Goldstone antenna could resolve features on the asteroid as small as 12 feet (3.75 meters) across, even from 4 million miles away. It is tremendously exciting to see detailed images of this asteroid for the first time, said Benner. With radar we can transform an object from a point of light into a small world with its own unique set of characteristics. In a real sense, radar imaging of near-Earth asteroids is a fundamental form of exploring a whole class of solar system objects. Asteroids, which are always exposed to the sun, can be shaped like almost anything under it. Those previously imaged by radar and spacecraft have looked like dog bones, bowling pins, spheroids, diamonds, muffins, and potatoes. To find out what 1998 QE2 looks like, stay tuned. Between May 30 and June 9, radar astronomers using NASA's 230-foot-wide (70 meter) Deep Space Network antenna at Goldstone, Calif., and the Arecibo Observatory in Puerto Rico, are planning an extensive campaign of observations. The two telescopes have complementary imaging capabilities that will enable astronomers to learn as much as possible about the asteroid during its brief visit near Earth. NASA places a high priority on tracking asteroids and protecting our home planet from them. In fact, the U.S. has the most robust and productive survey and detection program for discovering near-Earth objects. To date, U.S. assets have discovered over 98 percent of the known NEOs. In 2012, the NEO budget was increased from $6 million to $20 million. Literally dozens of people are involved with some aspect of near-Earth object (NEO) research across NASA and its centers. Moreover, there are many more people involved in researching and understanding the nature of asteroids and comets, including those that come close to the Earth, plus those who are trying to find and track them in the first place. In addition to the resources NASA puts into understanding asteroids, it also partners with other U.S. government agencies, university-based astronomers, and space science institutes across the country that are working to track and better understand these objects, often with grants, interagency transfers and other contracts from NASA. NASA's Near-Earth Object Program at NASA Headquarters, Washington, manages and funds the search, study, and monitoring of asteroids and comets whose orbits periodically bring them close to Earth. JPL manages the Near-Earth Object Program Office for NASA's Science Mission Directorate in Washington. JPL is a division of the California Institute of Technology in Pasadena. In 2016, NASA will launch a robotic probe to one of the most potentially hazardous of the known
[meteorite-list] NASA's Asteroid Sample Return Mission Moves into Development (OSIRIS-REx)
May 16, 2013 Dwayne Brown Headquarters, Washington 202-358-1726 dwayne.c.br...@nasa.gov Nancy Neal Jones Goddard Space Flight Center, Md. 301-286-0039 nancy.n.jo...@nasa.gov RELEASE: 13-143 NASA'S ASTEROID SAMPLE RETURN MISSION MOVES INTO DEVELOPMENT WASHINGTON -- NASA's first mission to sample an asteroid is moving ahead into development and testing in preparation for its launch in 2016. The Origins-Spectral Interpretation Resource Identification Security Regolith Explorer (OSIRIS-REx) passed a confirmation review Wednesday called Key Decision Point (KDP)-C. NASA officials reviewed a series of detailed project assessments and authorized the spacecraft's continuation into the development phase. OSIRIS-REx will rendezvous with the asteroid Bennu in 2018 and return a sample of it to Earth in 2023. Successfully passing KDP-C is a major milestone for the project, said Mike Donnelly, OSIRIS-REx project manager at NASA's Goddard Space Flight Center in Greenbelt, Md. This means NASA believes we have an executable plan to return a sample from Bennu. It now falls on the project and its development team members to execute that plan. Bennu could hold clues to the origin of the solar system. OSIRIS-REx will map the asteroid's global properties, measure non-gravitational forces and provide observations that can be compared with data obtained by telescope observations from Earth. OSIRIS-REx will collect a minimum of 2 ounces (60 grams) of surface material. The entire OSIRIS-REx team has worked very hard to get to this point, said Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona in Tucson. We have a long way to go before we arrive at Bennu , but I have every confidence when we do, we will have built a supremely capable system to return a sample of this primitive asteroid. The mission will be a vital part of NASA's plans to find, study, capture and relocate an asteroid for exploration by astronauts. NASA recently announced an asteroid initiative proposing a strategy to leverage human and robotic activities for the first human mission to an asteroid while also accelerating efforts to improve detection and characterization of asteroids. NASA's Goddard Space Flight Center in Greenbelt, Md. will provide overall mission management, systems engineering and safety and mission assurance. The University of Arizona in Tucson is the principal investigator institution. Lockheed Martin Space Systems of Denver will build the spacecraft. OSIRIS-REx is the third mission in NASA's New Frontiers Program. NASA's Marshall Space Flight Center in Huntsville, Ala., manages New Frontiers for NASA's Science Mission Directorate in Washington.

[meteorite-list] House-Pedigree-AD: Large Nininger Bondoc (244g) superb Nininger Estherville Indivdual (111g) with AML-Labels
Dear Collectors, today we want to accelerate especially the heartbeat of the lovers of documented historic specimens, in setting up for sale two of such, which would be without doubt also very remarkable, if they wouldn't be accompanied by their passports of provenience, the labels of the American Meteorite Laboratory. The American Meteorite Laboratory (AML) was founded in 1960 in Westminster, Colorado by H.H.Nininger's daughter Margaret and her husband Glenn Huss, to reestablish and continue the work of her father with his American Meteorite Museum, which he had finally to shut down for financial reasons in 1953. The AML had such an outreach in the institutional and private meteorite scene, that it served even as an eponym for the meteorite dealers of the following generation, like e.g. the Suisse Meteorite Laboratory and the Bavarian Meteorite Laboratory. Instead of giving you here the hundredth instant-biography of Nininger or Huss, we rather like to honor: The women! Who so undeservedly are standing small and faint behind the gloriole of their husbands, who never would have achieved that, they are celebrated for, if there hadn't been the support by the passion, the patience, the knowledge and the special abilities of their wives.(see also post scriptum). Therefore you get here for reading the obit for Margaret Huss, who died in 2007: http://www.denverpost.com/news/ci_5878113 Now to the exhibits: BONDOC. http://www.meteoritenhaus.de/img/Bondoc_244_g_004.JPG Bondoc was one of the largest coups ever of the Niningers. The story of the adventurous recovery is told in one of Al Mitterling's Nininger Moments: http://kuerzer.de/AlBondy Unfortunately the large slices cut from the huge main mass turned out to be everything else than stable and they crumbled and disintegrated to the harder iron nodules, manifold abundant in Bondoc, in larger silicate inclusions and crumbs of rust. The AML-Bondoc offered now is pretty massive and stable, looks like to be an endcut, and belongs to the iron-rich mesosideritic looking specimens, which seems to be scarcer than the preserved iron nodules and eucritic/silicate-inclusions. 244 gram it has! http://www.meteoritenhaus.de/img/Bondoc_244_g_001.JPG http://www.meteoritenhaus.de/img/Bondoc_244_g_002.JPG http://www.meteoritenhaus.de/img/Bondoc_244_g_003.JPG http://www.meteoritenhaus.de/img/Bondoc_244_g_004.JPG As you can see, in the last decades it had developed here and there some rust on the cut face. According to your wishes, we can re-polish it. (We have let it now as it is, because we know that most pedigree-collectors like their specimens to be as original as possible, also to keep the accordance of the specimen's weight with the given weight on the label). The second AMLer is a truly wonderful ESTHERVILLE http://www.meteoritenhaus.de/img/Estherville_111_g_005.JPG We guess, that Estherville doesn't need any introduction anymore here on the list, as it is the third largest observed fall of the U.S. Nevertheless it seems pretty difficult to find nowadays still entire individuals, better than the also hard to get popular nuggets. Here to your delight we have now a perfectly intact individual, which by all means would be also without the old label a premium collection-piece for your cabinet. Note that it has not only the thinner rougher fusion crust, but also the fat and bulgy one with bubbles from outgassing where the silicate constituents had been molten. 111 grams it has (and Nininger/Huss/AMM/AML-fans know, that Esthervilles with AML-Labels are so much rarer than the Bondocs). Enjoy! http://www.meteoritenhaus.de/img/Estherville_111_g_001.JPG http://www.meteoritenhaus.de/img/Estherville_111_g_002.JPG http://www.meteoritenhaus.de/img/Estherville_111_g_003.JPG http://www.meteoritenhaus.de/img/Estherville_111_g_004.JPG http://www.meteoritenhaus.de/img/Estherville_111_g_005.JPG Prices: Bondoc 244g $1350 Estherville 111g$1387 Both together: $2580 And for your patience, to have read the advertizing until that point, a third goodie: MURCHISON AT BELOW 100$/g All said about Murchison. The recent 5 years it got so sought after, that the standard price, even for larger stones, has established at 150$/g (and even 200-250$/g for minor amounts here and there and on ebay). Below you won't get any anymore. Here now a fragment, naked without crust and grinded on one side, At $800 with a weight of 8.13grams - which is 98.4$/g. The label on the back is looking familiar, but we didn't get it, from whom it could be. Maybe you can identify it? The font is outdated today, print looks like to stem from the time, when the printers still had needles. http://www.meteoritenhaus.de/img/Murchison_8_13_g_004.JPG http://www.meteoritenhaus.de/img/Murchison_8_13_g_001.JPG http://www.meteoritenhaus.de/img/Murchison_8_13_g_003.JPG Now time to let the games begin!

[meteorite-list] Nine-Year-Old Mars Rover Passes 40-Year-Old Record
http://www.jpl.nasa.gov/news/news.php?release=2013-166 Nine-Year-Old Mars Rover Passes 40-Year-Old Record Jet Propulsion Laboratory May 16, 2013 PASADENA, Calif. -- While Apollo 17 astronauts Eugene Cernan and Harrison Schmitt visited Earth's moon for three days in December 1972, they drove their mission's Lunar Roving Vehicle 19.3 nautical miles (22.210 statute miles or 35.744 kilometers). That was the farthest total distance for any NASA vehicle driving on a world other than Earth until yesterday. The team operating NASA's Mars Exploration Rover Opportunity received confirmation in a transmission from Mars today that the rover drove 263 feet (80 meters) on Thursday, bringing Opportunity's total odometry since landing on Mars in January 2004 to 22.220 statute miles (35.760 kilometers). Cernan discussed this prospect a few days ago with Opportunity team member Jim Rice of NASA Goddard Space Flight Center, Greenbelt, Md. The Apollo 17 astronaut said, The record we established with a roving vehicle was made to be broken, and I'm excited and proud to be able to pass the torch to Opportunity. The international record for driving distance on another world is still held by the Soviet Union's remote-controlled Lunokhod 2 rover, which traveled 23 miles (37 kilometers) on the surface of Earth's moon in 1973. Opportunity began a multi-week trek this week from an area where it has been working since mid-2011, the Cape York segment of the rim of Endeavour Crater, to an area about 1.4 miles (2.2 kilometers) away, Solander Point. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Exploration Rover Project for NASA's Science Mission Directorate, Washington. JPL also manages the Mars Science Laboratory Project and its rover, Curiosity, which landed on Mars in August 2012.
