[meteorite-list] Jupiter: Turmoil from Below, Battering from Above
http://www.jpl.nasa.gov/news/news.php?release=2012-328 Jupiter: Turmoil from Below, Battering from Above Jet Propulsion Laboratory October 17, 2012 Jupiter, the mythical god of sky and thunder, would certainly be pleased at all the changes afoot at his namesake planet. As the planet gets peppered continually with small space rocks, wide belts of the atmosphere are changing color, hotspots are vanishing and reappearing, and clouds are gathering over one part of Jupiter, while dissipating over another. The results were presented today by Glenn Orton, a senior research scientist at NASA's Jet Propulsion Laboratory, Pasadena, Calif., at the American Astronomical Society's Division for Planetary Sciences Meeting in Reno, Nev. The changes we're seeing in Jupiter are global in scale, Orton said. We've seen some of these before, but never with modern instrumentation to clue us in on what's going on. Other changes haven't been seen in decades, and some regions have never been in the state they're appearing in now. At the same time, we've never seen so many things striking Jupiter. Right now, we're trying to figure out why this is all happening. Orton and colleagues Leigh Fletcher of the University of Oxford, England; Padma Yanamandra-Fisher of the Space Science Institute, Boulder, Colo.; Thomas Greathouse of Southwest Research Institute, San Antonio; and Takuyo Fujiyoshi of the Subaru Telescope, National Astronomical Observatory of Japan, Hilo, Hawaii, have been taking images and maps of Jupiter at infrared wavelengths from 2009 to 2012 and comparing them with high-quality visible images from the increasingly active amateur astronomy community. Following the fading and return of a prominent brown-colored belt just south of the equator, called the South Equatorial Belt, from 2009 to 2011, the team studied a similar fading and darkening that occurred at a band just north of the equator, known as the North Equatorial Belt. This belt grew whiter in 2011 to an extent not seen in more than a century. In March of this year, that northern band started to darken again. The team obtained new data from NASA's Infrared Telescope Facility and the Subaru Telescope on Mauna Kea that matched up that activity with infrared observations. Those data showed a simultaneous thickening of the deeper cloud decks, but not necessarily the upper cloud deck, unlike the South Equatorial Belt, where both levels of clouds thickened and then cleared up. The infrared data also resolved brown, elongated features in the whitened area called brown barges as distinct features and revealed them to be regions clearer of clouds and probably characterized by downwelling, dry air. The team was also looking out for a series of blue-gray features along the southern edge of the North Equatorial Belt. Those features appear to be the clearest and driest regions on the planet and show up as apparent hotspots in the infrared view, because they reveal the radiation emerging from a very deep layer of Jupiter's atmosphere. (NASA's Galileo spacecraft sent a probe into one of these hotspots in 1995.) Those hotspots disappeared from 2010 to 2011, but had reestablished themselves by June of this year, coincident with the whitening and re-darkening of the North Equatorial Belt. While Jupiter's own atmosphere has been churning through change, a number of objects have hurtled into Jupiter's atmosphere, creating fireballs visible to amateur Jupiter watchers on Earth. Three of these objects - probably less than 45 feet (15 meters) in diameter - have been observed since 2010. The latest of these hit Jupiter on Sept. 10, 2012, although Orton and colleagues' infrared investigations of these events showed this one did not cause lasting changes in the atmosphere, unlike those in 1994 or 2009. It does appear that Jupiter is taking an unusual beating over the last few years, but we expect that this apparent increase has more to do with an increasing cadre of skilled amateur astronomers training their telescopes on Jupiter and helping scientists keep a closer eye on our biggest planet, Orton said. It is precisely this coordination between the amateur-astronomy community that we want to foster. The California Institute of Technology, Pasadena, operates the Jet Propulsion Laboratory for NASA.

[meteorite-list] Science of Global Climate Modeling Confirmed by Discoveries on Mars
NEWS RELEASE FROM THE PLANETARY SCIENCE INSTITUTE FROM: Alan Fischer Public Information Officer Planetary Science Institute 520-382-0411 520-622-6300 fisc...@psi.edu Science of Global Climate Modeling Confirmed by Discoveries on Mars Oct. 16, 2012, Tucson, Ariz. and Reno, Nev. -- Scientific modeling methods that predicted climate change on Earth have been found to be accurate on Mars as well, according to a paper presented at an international planetary sciences conference Tuesday. An international team of researchers from the Planetary Science Institute in Tucson, working with French colleagues, found that an unusual concentration of glacial features on Mars matches predictions made by global climate computerized models, in terms of both age and location. PSI Senior Scientist William K. Hartmann led the team, which included Francois Forget (Université Paris), who did the Martian climate modeling, and Veronique Ansan and Nicolas Mangold (Université de Nantes) and Daniel Berman (PSI), all of who analyzed spacecraft measurements regarding the glaciers. Some public figures imply that modeling of global climate change on Earth is 'junk science,' but if climate models can explain features observed on other planets, then the models must have at least some validity, said team leader Hartmann. Hartmann presented the report, Science of Global Climate Modeling: Confirmation from Discoveries On Mars, at the annual meeting of the Division of Planetary Sciences of the American Astronomical Society in Reno, Nev. The scientific team reached their conclusions by combining four different aspects of Martian geological mapping and Martian climate science in recent years. They noted that the climate models, the presence of glaciers, the ages of the glacial surface layers, and radar confirmation of ice in same general area, all gave consistent results - that the glaciers formed in a specific region of Mars, due to unusual climate circumstances, just as indicated by the climate model. The work has a long background. As early 1993, astronomers analyzed the changing tilt of Mars' rotational axis and found that during high-tilt Martian episodes, the axis tilt can exceed 45 degrees. Under this extreme condition, the summer hemisphere is strongly tilted toward the sun, and Mars' polar ice cap in that hemisphere evaporates, increasing water vapor in the Martian air, thus increasing the chances for snowfall in the dark, cold, winter hemisphere. The last such episodes happened on Mars 5 million to 20 million years ago. By 2001-2006, various French and American researchers applied the global climate computer models to study this effect. The computer programs were originally developed for planet Earth to estimate climate effects, from hurricane paths to CO2 greenhouse warming. Planetary scientists simply applied the Martian topography, atmosphere, and gravity, in order to run the computer calculations for Mars. The calculations indicated a strong concentration of winter snow and ice in a mid-latitude southern region of Mars, just east of a huge Martian impact basin named Hellas. At the same time, the PSI scientists independently discovered an unusual concentration of glacial features in a 40-mile-wide crater named Greg centered in the same region. Their analysis showed that the surface layers of the glaciers formed at the same time as the predicted climate extremes, about 5 million to 20 million years ago. The bottom line is that the global climate models indicate that the last few intense deposits of ice occurred about 5 million to 15 million years ago, virtually centered on Greg crater, and that's just where the spacecraft data reveal glaciers whose surface layers date from that time, Hartmann said. If global climate models indicate specific concentration of ice-rich features where and when we actually see them on a distant planet, then climate modeling should not be sarcastically dismissed. Our results provide an important, teachable refutation of the attacks on climate science on our home planet.
