[meteorite-list] LONEOS Discovers Asteroid with the Smallest Orbit (2004 JG6)
http://www.lowell.edu/press_room/releases/recent_releases/2004JG6_rls.html Lowell Observatory For Immediate Release May 20, 2004 contact: Steele Wotkyns (928) 233-3232 [EMAIL PROTECTED] LONEOS Discovers Asteroid with the Smallest Orbit Flagstaff, AZ-The ongoing search for near-Earth asteroids at Lowell Observatory has yielded another interesting object. Designated 2004 JG6, this asteroid was found in the course of LONEOS (the Lowell Observatory Near-Earth Object Search) on the evening of May 10 by observer Brian Skiff. I immediately noticed the unusual motion, said Skiff, so it was certain that it was of more than ordinary interest. He quickly reported it to the Minor Planet Center (MPC) in Cambridge MA, which acts as an international clearinghouse for asteroid and comet discoveries. The MPC then posted it on a Web page for verification by astronomers worldwide. It happened that all the initial follow up observations, however, were obtained by amateur and professional observers in the Southwest US. The additional sky positions measured in the ensuing few days allowed an orbit to be calculated. The official discovery announcement and preliminary orbit were published by the MPC on May 13. This showed that the object was located between Earth and Venus (presently the very bright evening star in the western sky). In addition, 2004 JG6 goes around the Sun in just six months, making it the asteroid with the shortest known orbital period. Ordinary asteroids are located between the orbits of Mars and Jupiter, roughly two to four times farther from the Sun than Earth, taking several years to go around the Sun. Instead, 2004 JG6 orbits entirely within Earth's orbit, only the second object so far found to do so. What makes this asteroid unique is that, on average, it is the second closest solar system object orbiting the Sun, said Edward Bowell, LONEOS Director. Only planet Mercury orbits closer to the Sun. As shown in the included diagram, JG6 crosses the orbits of Venus and Mercury, passing less than 30 million miles from the Sun every six months. The approximate average orbital speed of this asteroid is more than 30 km/sec, or 67,000 miles per hour. Depending on their locations, the asteroid may pass as close as 3.5 million miles from Earth and about 2 million miles from planet Mercury. In the coming weeks 2004 JG6 will pass between Earth and the Sun, just inside Earth's orbit. It will move through the constellations Cancer and Canis Minor low in the western sky at dusk. Because of the near-exact six-month period, the asteroid should be observable again in nearly the same spot in the sky next May, having gone around the Sun twice while Earth will have made only one circuit. From present estimates, 2004 JG6 is probably between 500 meters and 1 km in diameter. Despite its proximity, the object poses no danger of colliding with Earth. Asteroids with orbits entirely within the Earth's orbit have been informally called Apoheles, from the Hawaiian word for orbit. Apohele also has Greek roots: apo for outside, and heli for Sun. Objects orbiting entirely within Earth's orbit are thought by dynamicist William F. Bottke of Southwest Research Institute and colleagues to comprise just two percent of the total near-Earth object population, making them rare as well as difficult to discover. This is because they stay in the daylight sky almost all of the time. There may exist about 50 Apoheles of comparable size to or larger than 2004 JG6, but many of them are certain to be unobservable from the ground. The first asteroid found entirely inside Earth's orbit was 2003 CP20, found just over a year ago by the NASA-funded Lincoln Laboratory Near-Earth Asteroid Research project, which observes near Socorro, New Mexico. Although larger than 2004 JG6, 2003 CP20 is a little more distant from the Sun. LONEOS is one of five programs funded by NASA to search for asteroids and comets that may approach our planet closely. The NASA program's current goal is to discover 90 percent of near-Earth asteroids larger than 1 km in diameter by 2008. There are thought to be about 1,100 such asteroids. #END# For additional information: LONEOS = http://asteroid.lowell.edu/asteroid/loneos/loneos_disc.html MPC = http://cfa-www.harvard.edu/iau/mpc.html MPC's official discovery announcement: http://cfa-www.harvard.edu/mpec/K04/K04J60.html JPL orbit diagram/animations: http://neo.jpl.nasa.gov/cgi-bin/db_shm?sstr=2004+JG6 (for best results, copy and paste URL into browser) Static view of 2004 JG6 by Tom Polakis : http://www.psiaz.com/polakis/misc/2004JG6.jpg Diagram of 2004 JG6 by Larry Wasserman, Astronomer, Lowell Observatory (a pdf) __ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Mars Exploration Rover Update - May 20, 2004
http://marsrovers.jpl.nasa.gov/mission/status.html SPIRIT UPDATE: Spirit Gets an Unexpected Break. - sol 131-133, May 20, 2004 Spirit continued its trek to the Columbia Hills over the past four sols, but took an unplanned break on Sols 131 and 132 due to a software fault on sol 131. That fault left rover planners with some uncertainty about Spirit's final position and attitude, so Sol 132 was spent re-establishing that knowledge with panoramic, navigation and hazard avoidance camera imaging of the rover's surroundings. The unplanned break did have a silver lining though; it resulted in fully charged batteries, paving the way for a long drive on Sol 133. Spirit roved 113 meters (370.7 feet) on Sol 133, with a record 78-meter (256 feet) autonomous navigation segment. The previous record for an autonomous navigation drive was 62 meters (203.4 feet) on sol 125. Spirit's odometer now reads 2473 meters (1.53 miles) and it is roughly 780 meters (.5 miles) from the Columbia Hills and in excellent health. So what went wrong on sol 131? The flight software team is uncovering the details, but it appears that the error occurred within a 3-microsecond window of vulnerability when a write command was attempted to a write-protected area of RAM. The flight software team believes this is an extremely low probability event, and has not adjusted the planning process to avoid the miniscule period of vulnerability. Opportunity has the same vulnerability to the fault. __ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Theory Proposes New View of Sun and Earth's Creation
Contact: James Hathaway [EMAIL PROTECTED] 480-965-6375 Arizona State University May 20, 2004 Theory proposes new view of sun and Earth's creation Like most creation stories, this one is dramatic: we began, not as a mere glimmer buried in an obscure cloud, but instead amidst the glare and turmoil of restless giants. Or so says a new theory, supported by stunning astronomical images and hard chemical analysis. For years most astronomers have imagined that the Sun and Solar System formed in relative isolation, buried in a quiet, dark corner of a less-than-imposing interstellar cloud. The new theory challenges this conventional wisdom, arguing instead that the Sun formed in a violent nebular environment - a byproduct of the chaos wrought by intense ultraviolet radiation and powerful explosions that accompany the short but spectacular lives of massive, luminous stars. The new theory is described in a Perspectives article appearing in the May 21 issue of Science. The article was written by a group of Arizona State University astronomers and meteorite researchers who cite recently discovered isotopic evidence and accumulated astronomical observations to argue for a history of development of the Sun, the Earth and our Solar System that is significantly different from the traditionally accepted scenario. If borne out by future work, this vision of our cosmic birth could have profound implications for understanding everything from the size and shape of our solar system to the physical makeup of the Earth and the development of the chemistry of life. There are two different sorts of environment where low-mass stars like the Sun form, explained ASU astronomer Jeff Hester, the essay's lead author. In one kind of star-forming environment, you have a fairly quiescent process in which an undisturbed molecular cloud slowly collapses, forming a star here? a star there. The other type of environment in which Sun-like stars form is radically different. These are more massive regions that form not only low-mass stars, but luminous high-mass stars, as well. More massive regions are very different because once a high-mass star forms, it begins pumping out huge amounts of energy that in turn completely changes the way Sun-like stars form in the surrounding environment. People have long imagined that the Sun formed in the first, more quiescent type of environment, Hester noted, but we believe that we have compelling evidence that this is not the case. Critical to the team's argument is the recent discovery in meteorites of patterns of isotopes that can only have been caused by the radioactive decay of iron-60, an unstable isotope that has a half life of only a million and a half years. Iron-60 can only be formed in the heart of a massive star and thus the presence of live iron-60 in the young Solar System provides strong evidence that when the Sun formed (4.5 billion years ago) a massive star was nearby. Hester's coauthors on the Science essay include Steve Desch, Kevin Healy, and Laurie Leshin. Leshin is a cosmochemist and director of Arizona State University's Center for Meteorite Studies. One of the exciting things about the research is that it is truly transdisciplinary, drawing from both astrophysics and the study of meteorites - rocks that you can pick up and hold in your hand - to arrive at a new understanding of our origins, noted Leshin. When a massive star is born, its intense ultraviolet radiation forms an HII region - a region of hot, ionized gas that pushes outward through interstellar space. The Eagle Nebula, the Orion Nebula, and the Trifid Nebula are all well-known examples of HII regions. A shock wave is driven in advance of the expanding HII region, compressing surrounding gas and triggering the formation of new low-mass stars. We see triggered low-mass star formation going on in HII regions today, said Healy, who recently completed a study of radio observations of this process at work. The star does not have much time to get its act together, though. Within 100,000 years or so, the star and what is left of its small natal cloud will be uncovered by the advancing boundary of the HII region and exposed directly to the harsh ultraviolet radiation from the massive star. We see such objects emerging from the boundaries of HII regions,'' Hester said. These are the 'evaporating gaseous globules' or 'EGGs' seen in the famous Hubble image of the Eagle Nebula. EGGs do not live forever either. Within about ten thousand years an EGG evaporates, leaving behind only the low-mass star and its now-unprotected protoplanetary disk to face the brunt of the massive star's wrath. Like a chip of dry ice on a hot day, the disk itself now begins to evaporate, forming a characteristic tear-drop-shaped structure like the proplyds seen in Hubble images of the Orion Nebula. Once we understood what we were looking at, we realized that we had a number of images of EGGs caught just as they were turning into proplyds, said

[meteorite-list] Meteorite fall rates
My husband and I are doing battle with the Powers of Ignorance on one of his newsgroups. One of the nutbars on this particular newsgroup is claiming (among other things) that the gubbmint is covering up an increase in the rate of fall of meteors (their words, not mine). Could anyone out there point me to a reference I could use to refute this? As far as I know, the rate of fall of meteorites over the past several years has been pretty constant; the only reason we're finding more is that we're figuring out where to look, and there are more of us looking.
