Re: [meteorite-list] Big Sun-diving Comet Discovered: Comet C/2012 S1(ISON)
Hi Ron/List, Given the length of the current arc (270 days), and the consistency of the photometry over that time, I will go out on a limb and say that this will almost certainly become the brightest comet that has ever been seen -- by a significant margin -- by most people alive today. What's particularly amazing is how close this comet will come to Mars around October 1st next year -- less than 7 million miles! Hopefully NASA/JPL will have plans in the works to schedule instrument pointing and imaging of the comet using the suite of sensors both on and in orbit around the Red Planet. For Mars, this will be a northern hemisphere comet -- certainly visible from both rovers. --Rob -Original Message- From: meteorite-list-boun...@meteoritecentral.com [mailto:meteorite-list-boun...@meteoritecentral.com] On Behalf Of Ron Baalke Sent: Tuesday, September 25, 2012 8:57 AM To: Meteorite Mailing List Subject: [meteorite-list] Big Sun-diving Comet Discovered: Comet C/2012 S1(ISON) Space Weather News for Sept. 25, 2012 http://spaceweather.com SUNDIVING COMET: Astronomers are paying close attention to a newly-discovered comet, C/2012 S1 (ISON), which is heading for a remarkably close encounter with the sun.

Some early estimates are that close to perihelion, the comet's tail could span more than 90 degrees as seen from earth. Haven't read any estimates yet on the expected angular size of the coma surrounding the nucleus.

[meteorite-list] Enstatite Connection to Mercury
Pete, That's right, no evidence for an angrite composition on the surface of Mercury -- at least not yet. Angrites have far too much FeO in the silicates to match the spectra of Mercury. Also, angrites are among the oldest igneous rocks in the solar system (SAH 99555 is probably the oldest known igneous rock), and you would expect to see somewhat younger ages from a planet (like Mercury or Mars) or even a large body like our Moon -- it takes millions of years to differentiate and form a crust. Who knows, maybe some aubrites are from Mercury, or maybe we need to keep searching! Best regards, Carl Agee -- Carl B.

[meteorite-list] Comet C/2012 S1 (ISON): Super-Comet or Super-Dud?
http://cosmiclog.nbcnews.com/_news/2012/09/25/14096323-super-comet-or-super-dud-well-see?lite Super-comet or super-dud? We'll see By Alan Boyle Cosmic Blog September 25, 2012 A new comet superstar named C/2012 S1 (ISON) is heading for the spotlight starting in November 2013 - but will it perform as some hope it will, or will it be a dud of cosmic proportions? This is one to watch, definitely, said Karl Battams, a scientist at the Naval Research Laboratory who monitors comets for the NASA-supported Sungrazer Comet Project http://sungrazer.nrl.navy.mil/. But the astronomy community in general tries not to overhype these things. Potentially it will be amazing. Potentially it will be a huge dud. Comet ISON quickly rose to the top of the charts after its discovery, which was based on imagery collected on Friday by the International Scientific Optical Network's http://lfvn.astronomer.ru/report/029/index.htm 16-inch (0.4-meter) Santel reflecting telescope in Russia. The comet, which was described in an IAU circular http://www.cbat.eps.harvard.edu/iau/cbet/003200/CBET003238.txt on Monday, takes its common name from the network's acronym. Since the discovery, astronomers have gone back through their files to find pre-discovery images and calculate the comet's orbit. That orbit is due to bring Comet ISON incredibly close to the sun - within just 1.1 million miles (1.8 million kilometers) in late November of next year. As a result, current projections suggest it could get very bright. How bright? Various estimates have set the brightest magnitude at -10 to -16. That suggests the comet could become brighter than the full moon - which led Astronomy Magazine's Michael E. Bakich to say it probably will become the brightest comet anyone alive has ever seen. Over the next year, you're going to hear a lot of comparisons to stunners of the past, as long ago as the Great Comet of 1680 http://en.wikipedia.org/wiki/Great_Comet_of_1680 and as recent as the Great Comet of 2007 http://en.wikipedia.org/wiki/C/2006_P1. You'll also hear comparisons to past letdowns, ranging from Comet Kohoutek http://en.wikipedia.org/wiki/Comet_Kohoutek to Comet Elenin http://www.msnbc.msn.com/id/44555050/ns/technology_and_science-space/t/doomsday-comet-fades-away/. You may also hear a fresh wave of doomsday talk, like the ridiculous rumblings that accompanied Elenin's approach http://www.msnbc.msn.com/id/45050612/ns/technology_and_science-space/t/comet-elenin-dead-along-doomsday-predictions/. Don't believe anything you hear about a comet catastrophe - and don't get your hopes up just yet for a comet extravaganza. But do make plans to keep an eye on the sky in late 2013. Battams said a lot depends on Comet ISON's composition. It could turn into a huge letdown if it's a comet that's just too fragile and dissipates as it makes its way into the inner solar system, he told me. That's basically what happened to Comet Elenin. Because ISON appears to be a new comet coming in from the far-flung Oort cloud, it's tough to predict how the comet will behave. The comet is currently in the constellation Cancer, as indicated in this star chart from Astronomy Magazine. When the comet hits prime time, a year from now, it should be heading through the constellation Virgo and visible from northern latitudes before sunrise. Here's a night-sky animation http://www.fototime.com/95413C237AB9209/convx264.mp4 from the Remanzacco Observatory that shows how things are likely to go down. During the months ahead, astronomers of all stripes will be keeping a watch on Comet ISON and refining their expectations. I would imagine that by next summer, we should have a much better handle on it, Battams said. __ 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

There is always the possibility of an unexpected outburst. Just a few years back, we saw that with comet Holmes (2007 or 2008?). That comet provided a lot of great observing for weeks before it faded and nobody saw that outburst coming. Under moderately bright urban skies, Holmes achieved naked eye visibility. This new comet could put on a similar show. -- - Web - http://www.galactic-stone.com Facebook - http://www.facebook.com/galacticstone Twitter - http://twitter.com/GalacticStone Pinterest - http://pinterest.com/galacticstone RSS - http://www.galactic-stone.com/rss/126516 - On 9/25/12, Matson, Robert D. robert.d.mat...@saic.com wrote: Some early estimates are that close to perihelion, the comet's tail could span more than 90 degrees as seen from earth.

[meteorite-list] Trajectory for Earth-grazing UK bolide of 9/21/2012
Hi All, Been a little slow to report this to the Meteorite List -- got a little side-tracked with comet C/2012 S1, and was waiting to do a little more analysis to confirm the solution. Let me start with the analysis result, since it's pretty exciting: the UK bolide of 21 September 2012 was an earth-grazer: it's pre- earth-encounter trajectory did NOT intersect the earth! It came very close -- a minimum altitude of about 57 km over western Ireland. Coincidentally, this is the same minimum altitude that was achieved by the Grand Teton Daytime Fireball of 1972, although that encounter lacked the significant fragmentation seen last Friday.) Thanks to that fragmentation coupled with the low altitude, some meteorites may have actually made it to the ground (or more likely the ocean). But a significant fraction of the original meteoroid went right back into space. Depending on the velocity (which I would need a good video to estimate), the original asteroid's orbit may have been sufficiently aerobraked to have been captured by earth's gravity. If so, then the remaining fragments would have reentered for good one orbit later in the middle of the North Atlantic. I know this is a bit of bad news as far as meteorite recovery, but it's nevertheless an important result since it is one of the extremely rare instances of an earth-grazing asteroid being not only witnessed by hundreds if not thousands of people, but also imaged by multiple cameras, both still and video. Three key images showing excellent star background references were what allowed me to compute the trajectory: 1. Damien Stenson's beautiful image taken just south of O'Brien's Tower on the Cliffs of Moher in County Clare, Ireland. At least four bright fragments pass through the bowl of the Big Dipper, behind the central tower and then disappear behind clouds low in the west-northwest. http://www.worldirish.com/story/12297-photographer-captures-stunning-image-of-fireball-fragments-at-cliffs-of-moher 2. Craig Usher's shot from Greenock, Scotland, facing southwest shows the tracks of at least five individual fragments. Four of these appear to be the same ones captured by Damien Stenson. http://www.bbc.co.uk/news/uk-19683687 3. Truls Gabrielsen's time-lapse photography from Skjernøya, Mandal, Norge (southern Norway) includes two frames showing the bolide track very low in the southwest sky: http://www.aftenposten.no/nyheter/iriks/--Meteoritten-lyste-intenst-og-knallgront-6999353.html Since the first two images show the meteor tracks from closer range than the third (and thus at higher elevation angles), these were my main sources for astrometric measurements. When I triangulate these two, the point of closest approach to the earth was near 54.18 N, 8.25 W, altitude 57 km -- a sub-meteoroid point about 10 miles southeast of Sligo, Ireland. The bearing at that point was toward azimuth 263 (7 degrees south of west). When the meteoroid was over England, the local bearing was nearly due west. As a cross-check, I triangulated using images 1 and 3. The solution there is nearly parallel to the first solution, just shifted slightly to the south. (Due to the very low elevation angles from Norway, a very small change in the measured angles leads to a significant shift in the north-south position of the track). Some towns underneath my computed trajectory in order from east to west are: In England (UK): Whitby, Danby, Stokesley, Crathorne, Dalton-on-Tees, Melsonby, Kirby Steven, Tebay, Ambleside, Loughrigg and Gosforth. Isle of Man: Cranstal and The Lhen. In Northern Ireland (UK): Strangford, Saul, Downpatrick, Loughinisland, Katesbridge, Loughbrickland, Acton, Poyntzpass, Markethill, Lisnadill In Ireland: Silverstream, Willowbridge, Monaghan, Ballinode Back into Northern Ireland: Lisnaskea, Kinawley Back into Ireland: Coppanaghbane, Corrard, Dowra, Drumkeeran, Collooney, Coolaney, Ballina, Crossmolina, Owenglass, Lagduff More, and finally Doona. I'm very much indebted to David Entwistle of the British and Irish Meteorite Society for contacting me with links to these three images. I would also like to thank list member Martin Goff for posting his early report to the list last Friday, and George Herbert at MPML for forwarding David Jordan's Seesat-L post in which he reported seeing the fragmenting fireball (which at the time he thought might be a satellite reentry) from south Dublin, Ireland.

[meteorite-list] Mars Sample-Return Goal Drives NASA's Exploration of Red Planet
http://www.space.com/17757-mars-sample-return-nasa-future-missions.html Mars Sample-Return Goal Drives NASA's Exploration of Red Planet by Mike Wall space.com 25 September 2012 The next steps in NASA's Mars exploration strategy should build toward returning Martian rocks and dirt to Earth to search for signs of past life, a new report by the space agency's Red Planet planning group finds. The report, released today (Sept. 25) by the Mars Program Planning Group (MPPG), lays out a series of options that NASA could employ to get pieces of the Red Planet in scientists' hands here on Earth. The space agency is now mulling those options and could announce its chosen path by early next year, when the White House releases its proposed budget for fiscal year 2014. The first public release of what plans, you know, we definitively have would not be until the president presents that budget to Congress in February of 2013, John Grunsfeld, associate administrator for NASA's Science Mission Directorate, told reporters today. NASA put together the MPPG this past March to help restructure its Mars strategy in the wake of cuts to the space agency's robotic exploration program. The MPPG was instructed to consider NASA's newly constrained fiscal situation and the priorities laid out by the U.S. National Research Council's Planetary Decadal Survey, which was released last year. President Barack Obama's directive that the agency get astronauts to the vicinity of Mars by the mid-2030s was another factor, NASA officials said. The MPPG's focus on sample-return should thus come as no surprise. It was a top priority of the Decadal Survey, and sample-return could help spur and work in concert with NASA's plans for human exploration of Mars, Grunsfeld said. [7 Biggest Mysteries of Mars] Sample-return represents the best opportunity to find symmetry technologically between the programs, he said. Sending a mission to go to Mars and return a sample looks a lot like sending a crew to Mars and returning them safely. Humans could even be involved in the sample-return process, according to the MPPG report. Astronauts aboard NASA's Orion capsule, which is currently under development, could intercept the Martian sample in deep space, secure it in a contained environment, and bring it safely down to Earth. It is taking advantage of the human architecture, because we anticipate it will be there, Grunsfeld said. And it potentially solves an issue of, when we return samples, somewhere we have to make sure that the samples are completely contained so there's no chance - remote as it may be - that there is something on Mars that could contaminate Earth. Exactly when a Martian sample could come down to Earth remains up in the air. But NASA is considering launching the first enabling mission along this path in 2018, or perhaps 2020, Grunsfeld said. A complicating factor is that NASA has just $800 million or so to work with for the project through 2018. That's not enough to encompass the rover options that we talked about, said MPPG team lead Orlando Figueroa. That drives you to either launching an orbiter first, or delaying to the next opportunity, 2020, to start with a rover. The report also provides a variety of options for gathering and returning Red Planet samples. For example, it could all be done with a single launch, which would carry a soil-collecting rover, a vehicle that would blast the samples off the Martian surface and an orbiter for sample rendezvous and return. Or these payloads could be divided among two or three launches, to spread cost and risk around, Figueroa said. The MPPG report discusses lofting the single-shot mission as early as 2024, aboard NASA's huge Space Launch System rocket. NASA wants the SLS to make its first test flight by 2017 and to be ready to carry crews by 2021. NASA's robotic Mars exploration strategy has already begun shifting from follow the water - exemplified by NASA's Spirit and Opportunity rovers - to searching for habitable environments, which the $2.5 billion Curiosity rover is currently doing in the Red Planet's Gale Crater. Sample-return is the logical next step in NASA's unmanned activities at Mars, Figueroa said. This is really the search for evidence of past life, he said. And the options that we are putting forth is, What are the options that NASA could have available to pursue it in the most aggressive way possible? NASA has two robotic Mars missions on the docket before the first step toward sample-return would launch. The Maven orbiter is slated to blast off next year to study the Red Planet's atmosphere, while a mission called InSight will launch in 2016 to probe Mars' core. __ 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

Re: [meteorite-list] Meteorite of Anu
Hi Phil, The epic of Gilgamesh is a great tale. Here is what I think it is about: The passage that you refer to has 2 dreams in it, in the first the meteorite of Anu is falling and in the second an ax appears at the gate to his marital chamber. The meteorite of Anu is an omen. It foretells of the coming of a powerful man who Gilgamesh will compete with and love as he would his wife. His next dream about the axe has the same meaning. Needless to say the dreams come true with the arrival of Enkidu, the primal man who becomes Gilgamesh's sidekick and lover. They each tried to outdo the other. The meteorite of Anu appears in an earlier Babylonian tale. The dream is similar but the King is able to lift the meteorite with the help of his nobles. He doth not make love to it as he did in the latter Assyrian version. In the earlier version a meteorite was a thing to be controlled by man or at least by a man- god like Gilgamesh. By the time the Assyrian version is recorded the meteorite is beyond man's control and is immovable and worshiped as a god. It is possible that an actual meteorite fell near the time of the writing of the Babylonian version. When the Assyrian version was recorded the truth of the meteorite had faded and all that was left of it was its mythic power.

(From the Epic of Gilgamesh.) Gilgamesh got up and revealed the dream, saying to his mother: Mother, I had a dream last night. Stars of the sky appeared, and some kind of meteorite of Anu fell next to me. I tried to lift it but it was too mighty for me, I tried to turn it over but I could not budge it. The Land of Uruk was standing around it, the whole land had assembled about it, the populace was thronging around it, the Men clustered about it, and kissed its feet as if it were a little baby. I loved it and embraced it as a wife. I laid it down at your feet, and you made it compete with me.
