Something is going on right now. Six fireballs in one night from the OKC camera - all of them short. The week has been empty with almost nothing, then BAM, all of these. One particular event was to our WSW around the time of this one, but after reading the description, I think they are separate. About half of the radiants appear to be from Auriga / Perseus. Is anyone else seeing this? Very active night How fast do they appear? Are you sure these aren't Orionids?

[meteorite-list] Volcano... Or Giant Impact?
An interesting study, with implications for how we think giant impacts behave. Sterling K. Webb http://www.space.com/13325-gas-blast-meteorite-strike-resembled-volcanic-eruption.html Ancient Meteorite Blast Resembled Volcanic Eruption A billion years ago, a meteorite slammed into the Earth along the coast of what is now Scotland. A forensic investigation by a team of volcanologists has pieced together exactly how the debris from the impact devastated the surrounding region. The new research shows that some aspects of giant meteorite impacts may mimic the behavior of large volcanic eruptions. Meteorite impacts are more common than most people realize, but what happens when the meteorite hits? Direct observation is understandably difficult, but researchers can pick through impact debris that hasn't eroded away and then forensically reconstruct these catastrophic events. The volcanologists say that an improved understanding of what happens when large objects hit the Earth will help us understand how such events affect life on the planet. Volcanologists analyzed a layer of ejected debris from this huge meteorite impact and discovered that much of the debris moved across the ground as rapid, dense, ground-hugging currents of gas and debris, remarkably similar to the pyroclastic density currents — fast-traveling streams of hot ash and rock — that flow outward from explosive volcanoes. In particular, the way that ash and dust stick together seems identical, said study team member Mike Branney of the University of Leicester in England. Moist ash from explosive volcanoes sticks together in the atmosphere to fall out as millimeter-sized pellets. Where these drop back into a hot pyroclastic density current, they grow into larger layered structures, known as accretionary lapilli. The researchers studied the finely preserved deposit in northwest Scotland from the ancient impact. It shows both types of these 'volcanic' particles — pellets and lapilli — are produced. This reveals that that the 10 meter-thick [33 feet] layer, which has been traced for over 50 km [31 miles] along the Scottish coast, was almost entirely emplaced as a devastating density current that sped outwards from the point of impact — just like a density current from a volcano. Only the uppermost few centimeters actually fell out through the atmosphere, said study team member Richard Brown of the University of Durham. __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] NASA's Spitzer Detects Comet Storm in Nearby Solar System
http://www.jpl.nasa.gov/news/news.cfm?release=2011-322 NASA's Spitzer Detects Comet Storm in Nearby Solar System Jet Propulsion Laboratory October 19, 2011 PASADENA, Calif. -- NASA's Spitzer Space Telescope has detected signs of icy bodies raining down in an alien solar system. The downpour resembles our own solar system several billion years ago during a period known as the Late Heavy Bombardment, which may have brought water and other life-forming ingredients to Earth. During this epoch, comets and other frosty objects that were flung from the outer solar system pummeled the inner planets. The barrage scarred our moon and produced large amounts of dust. Now Spitzer has spotted a band of dust around a nearby bright star in the northern sky called Eta Corvi that strongly matches the contents of an obliterated giant comet. This dust is located close enough to Eta Corvi that Earth-like worlds could exist, suggesting a collision took place between a planet and one or more comets. The Eta Corvi system is approximately one billion years old, which researchers think is about the right age for such a hailstorm. We believe we have direct evidence for an ongoing Late Heavy Bombardment in the nearby star system Eta Corvi, occurring about the same time as in our solar system, said Carey Lisse, senior research scientist at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., and lead author of a paper detailing the findings. The findings will be published in the Astrophysical Journal. Lisse presented the results at the Signposts of Planets meeting at NASA's Goddard Space Flight Center in Greenbelt, Md., today, Oct. 19. Astronomers used Spitzer's infrared detectors to analyze the light coming from the dust around Eta Corvi. Certain chemical fingerprints were observed, including water ice, organics and rock, which indicate a giant comet source. The light signature emitted by the dust around Eta Corvi also resembles the Almahata Sitta meteorite, which fell to Earth in fragments across Sudan in 2008. The similarities between the meteorite and the object obliterated in Eta Corvi imply a common birthplace in their respective solar systems. A second, more massive ring of colder dust located at the far edge of the Eta Corvi system seems like the proper environment for a reservoir of cometary bodies. This bright ring, discovered in 2005, looms at about 150 times the distance from Eta Corvi as the Earth is from the sun. Our solar system has a similar region, known as the Kuiper Belt, where icy and rocky leftovers from planet formation linger. The new Spitzer data suggest that the Almahata Sitta meteorite may have originated in our own Kuiper Belt. The Kuiper Belt was home to a vastly greater number of these frozen bodies, collectively dubbed Kuiper Belt objects. About 4 billion years ago, some 600 million years after our solar system formed, scientists think the Kuiper Belt was disturbed by a migration of the gas-giant planets Jupiter and Saturn. This jarring shift in the solar system's gravitational balance scattered the icy bodies in the Kuiper Belt, flinging the vast majority into interstellar space and producing cold dust in the belt. Some Kuiper Belt objects, however, were set on paths that crossed the orbits of the inner planets. The resulting bombardment of comets lasted until 3.8 billion years ago. After comets impacted the side of the moon that faces Earth, magma seeped out of the lunar crust, eventually cooling into dark seas, or maria. When viewed against the lighter surrounding areas of the lunar surface, those seas form the distinctive Man in the Moon visage. Comets also struck Earth or incinerated in the atmosphere, and are thought to have deposited water and carbon on our planet. This period of impacts might have helped life form by delivering its crucial ingredients. We think the Eta Corvi system should be studied in detail to learn more about the rain of impacting comets and other objects that may have started life on our own planet, Lisse said.

[meteorite-list] Mars Rover Opportunity Update: October 7-13, 2011
http://marsrovers.jpl.nasa.gov/mission/status.html#opportunity OPPORTUNITY UPDATE: Opportunity Keeps Rolling With an Eye on Future Havens for Next Winter - sols 2738-2744, October 07-13, 2011: Opportunity is moving generally north across Cape York on the rim of Endeavour crater with an eye ahead to the next winter. With her solar arrays dustier and atmospheric opacity higher than in past years, the winter will be more challenging. So, Opportunity has been surveying regions with favorable northerly tilts so she can spend the winter months actively exploring. On Sol 2738 (Oct. 7, 2011), the rover drove north toward the feature Shoemaker Ridge with a 28-meter (92-foot) drive. On the next sol, Opportunity continued her scouting trek with a 78-meter (256-foot) drive to the north-northeast. On Sol 2742 (Oct. 11, 2011), the rover conducted a reconnaissance of the local area with a zigzag drive totaling almost 40 meters (131 feet). The plan ahead is more northward driving surveying Cape York. As of Sol 2744 (Oct. 13, 2011), solar array energy production was 316 watt-hours with an atmospheric opacity (Tau) of 0.791 and a solar array dust factor of 0.498. Total odometry is 20.98 miles (33,761.36 meters, or 33.7 kilometers). __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

One of the principal characteristics of impact events is the formation and emplacement of ejecta deposits. An understanding of impact ejecta deposits, and their components, is critical for the results of planetary exploration; particularly future sample return missions. Their compositional and physical characteristics provide fundamental information about the sub-surface of planets. Current models of ejecta emplacement, however, do not account for several important observations of planetary ejecta deposits; in particular, the presence of double or multiple layers of ejecta. Further, there is also no universal model for the origin and emplacement of ejecta on different planetary bodies. Here, we present a new working model for the origin and emplacement of ejecta on the terrestrial planets, in which ejecta is emplaced in a multi-stage process. Critical observations from the terrestrial planets: It is generally acknowledged that proximal ejecta deposits around impact craters on airless bodies, such as the Moon and Mercury, are emplaced via the process of ballistic sedimentation – this results in the incorporation of local material (secondary ejecta) in the primary ejecta, via considerable modification and erosion of the local external substrate [1]. A typically overlooked, but critical, observation is that proximal ejecta may consist of more than one layer. Moon and Mercury.On the Moon, melt ponds on the rim terraces of complex lunar craters and overlying parts of continuous ejecta have been documented since the 1970s [2] (Fig. 1a). The interpretation is that these deposits consist of impact melt that has flowed and pooled according to local slopes, after its initial emplacement as ejecta. This is consistent with observations from the Lunar Reconnaissance Orbiter Camera (LROC) (Fig. 1b). Images recently returned by the Messenger spacecraft show the presence of what is interpreted as melt ponds around several Mercurian impact craters [3]. If ballistic sedimentation followed by radial flow accounts for the emplacement of the continuous ballistic ejecta, it begs the question as to the origin of this overlying melt-rich ejecta observed around many lunar and Mercurian craters. Venus. The relative increase in the volume of impact melt produced on Venus, for a given transient crater size, compared to the Moon is manifest as spectacular melt outflows exterior to Venusian craters [4]. Several factors complicate the interpretation of these outflows around Venusian craters and not all may have the same origin; however, they share many traits with exterior lunar impact melt deposits and ponds. Fig. 1. (a) Large impact melt (“m”) pond around King Crater crater. Portion of Apollo 16 image 1580 (NASA). (b) A portion of LROC NAC image pair (M106209806RE) of melt overlying the continuous ejecta blanket at Giordano Bruno crater (NASA/GSFC/ASU). Earth. Ejecta deposits are relatively rare due to high rates of erosion on Earth; however, given the ability to ground truth, any model must be consistent with the interpretation of the characteristics of ejecta deposits on Earth, if it is to be generally applicable. The nature, lithological and stratigraphic relations of ejecta at several buried complex structures are known only from drill core but indicate the presence in the proximal ejecta of a low-shock, lithic breccia overlain by melt-bearing deposits. Some of the best preserved and exposed ejecta deposits on Earth occur

The rock layer, which stretches from Gairloch in the south to the Sutherland village of Stoer to the north, is sandwiched between sedimentary rocks which form part of the Torridonian sandstones of Sutherland. This reveals that that the 10 meter-thick [33 feet] layer, which has been traced for over 50 km [31 miles] along the Scottish coast, was almost entirely emplaced as a devastating density current that sped outwards from the point of impact — just like a density current from a volcano. Only the uppermost few centimeters actually fell out through the atmosphere, said study team member Richard Brown of the University of Durham. http://www.space.com/13325-gas-blast-meteorite-strike-resembled-volcanic-eruption.html Ancient Meteorite Blast Resembled Volcanic Eruption OurAmazingPlanet Staff Date: 19 October 2011 Time: 11:33 AM ET A billion years ago, a meteorite slammed into the Earth along the coast of what is now Scotland. A forensic investigation by a team of volcanologists has pieced together exactly how the debris from the impact devastated the surrounding region. The new research shows that some aspects of giant meteorite impacts may mimic the behavior of large volcanic eruptions. Meteorite impacts are more common than most people realize, but what happens when the meteorite hits? Direct observation is understandably difficult, but researchers can pick through impact debris that hasn't eroded away and then forensically reconstruct these catastrophic events. The volcanologists say that an improved understanding of what happens when large objects hit the Earth will help us understand how such events affect life on the planet. Volcanologists analyzed a layer of ejected debris from this huge meteorite impact and discovered that much of the debris moved across the ground as rapid, dense, ground-hugging currents of gas and debris, remarkably similar to the pyroclastic density currents — fast-traveling streams of hot ash and rock — that flow outward from explosive volcanoes. In particular, the way that ash and dust stick together seems identical, said study team member Mike Branney of the University of Leicester in England. Moist ash from explosive volcanoes sticks together in the atmosphere to fall out as millimeter-sized pellets. Where these drop back into a hot pyroclastic density current, they grow into larger layered structures, known as accretionary lapilli. The researchers studied the finely preserved deposit in northwest Scotland from the ancient impact. It shows both types of these 'volcanic' particles — pellets and lapilli — are produced. This reveals that that the 10 meter-thick [33 feet] layer, which has been traced for over 50 km [31 miles] along the Scottish coast, was almost entirely emplaced as a devastating density current that sped outwards from the point of impact — just like a density current from a volcano. Only the uppermost few centimeters actually fell out through the atmosphere, said study team member Richard Brown of the University of Durham.

That's according to the combined forces of the University of Oxford and the University of Aberdeen, who say that unusual rock formations previously thought to have volcanic origins are actually the debris ejected from a meteorite strike which threw material over an area 50 km across.
