Re: [meteorite-list] Meteorites as Ammunition
It wouldn't be practical to melt meteorites to make musket balls. That's not to say that iron meteorites couldn't be used as ammunition just as they are. The blunderbuss had a large enough bore and muzzle to accpt smaller meteorites as is. In fact it wasn't uncommon for users of the blunderbuss to load it with rocks, nails, and anythnig else that happened to be around. Same with canons.

Re: [meteorite-list] Meteorites as Ammunition
I never saw the movie, but there are plenty of historical references to cannoneers using scrap of all kinds (metal, glass, rocks, gravel, lengths of chain, etc.). The common commercially-made equivalent ammunition was grapeshot and canister rounds. Getting hit with grapeshot or a canister round would definitely make your eyes water.

thats the melting point for pure iron. The Ni works like antifreeze and lowers the melting range about 50 degrees.

1) When did you start collecting? (how long ago) 2) What first interested you about meteorites? 3) What was your first meteorite purchase, and from whom? 4) How many meteorites or localities do you currently have in your collection? 5) If you had to know for insurance purposes, what do you value your entire collection at? - in dollars - ballpark figure OK, or just say none of your business. 6) What is your favorite meteorite and why? 7) Have you ever found a meteorite in the field? 8) Did you ever get the deal of a lifetime on a meteorite? If so, what was it? 9) Did you ever go through the ordeal of a lifetime to obtain a meteorite? If so, please explain. 10) Have you ever consumed meteoritic material? (If so, how or under what circumstances?) 11) Does your spouse share your meteorite passion, is ambivalent towards it, or resents it? 12) Have you ever let a bill go unpaid or late to buy a meteorite? 13) A perfectly oriented, fully crusted, baseball-sized, lunar meteorite crashes through your roof and lands in your lap while you are reading this. It's the most gorgeous aesthetically-superior specimen you have ever seen - like Lafayette, but better. It legally belongs to you. What do you do with it? 14) Statistics have caught up with someone. Anne Hodges will no longer be the only documented person to be struck by a falling meteorite. Assuming the next person struck could be anyone and you could pick that person, who would it be? (silly answers only, nothing mean or political) 15) You are awarded the honor of selecting one specimen to keep from any meteorite collection in the world. What would it be? 16) Have you ever sold or donated your entire collection, and then had to rebuild it? 17) Summarize what you think about tektites in one sentence. 18) Which do you prefer - thin sections, whole specimens, slices, or endcuts? 19) Do you collect meteorwrongs? 20) Have you ever dropped a tiny crumb of a rare meteorite and lost it? -- Mike Gilmer - Galactic Stone Ironworks Meteorites http://www.galactic-stone.com http://www.facebook.com/galacticstone __ 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] Dawn Journal - July 26, 2010
http://dawn.jpl.nasa.gov/mission/journal_07_26_10.asp Dawn Journal Dr. Marc Rayman July 26, 2010 Dear Dawn Days of Summers, Dawn is flying smoothly through the asteroid belt, now less than a year from entering orbit around Vesta, the first of its two cosmic destinations. Earlier in July, while the spacecraft was devoting its time to gentle thrusting with its ion propulsion system, members of the mission control team spent some of their time in August 2011. Impressively capable as NASA is, time travel is not within its powers. (If it were, your correspondent could travel back in time after this is posted to remove his controversial and inappropriate comments above, thereby preventing anyone from ever having seen them and avoiding the regrettable consequences of his poor judgment. Alas, that awaits a future capability.) Instead, the team simulated being in the future, when Dawn will be finishing its approach to survey orbit around Vesta, where it will begin its intensive scrutiny of the alien world. That will be a very busy period not only for the spacecraft but also for the human members of the team. To account for details of the normal variations in the trajectory (as illustrated in a log last year http://dawn.jpl.nasa.gov/missionjournal_1_27_09.asp#navigators) as well as the properties of the protoplanet that will be determined as Dawn closes in on it, controllers may adjust the sequences of commands that are being developed this year for execution at Vesta . For example, once the brightness of different regions of the surface is known, the instructions for the science instruments to perform their observations may need to be changed accordingly. The procedures to make these modifications reliably are complex, and the time available between receiving the pertinent data from the spacecraft and radioing the refined sequences back often will be only a few days. The team has formulated detailed schedules for all the necessary work, including the checks needed at every step. Engineers have established the criteria for making revisions, determined exactly what data must be presented and in what format for each meeting at which a decision will need to be made, and developed the computer programs to be used for verifying that no unintentional changes are made along with the intentional ones. For these complex operations involving many participants, the team cannot wait until arrival at Vesta to verify that the plans are sound, so they rehearse major elements of it. Such operational readiness tests, or ORTs, also were conducted before launch. This time, with great creativity and care, some engineers had concocted data from the science instruments and navigational data, all representing results from the approach phase. The rest of the operations team treated the data as if they were real and went through all the steps to be followed when Dawn is nearly ready to begin surveying Vesta. The ORT was successful, concluding with your correspondent providing the final approval to transmit the fine-tuned sequences to the spacecraft. The ORT allowed team members to identify opportunities for improvements in their software tools and procedures, such as parts of the schedule that allowed more time than needed for some steps and not enough time for others. While such details may seem prosaic, they are essential for the accomplishment of a grand and challenging endeavor. All the improvements will be incorporated into the final plans for how operations will be conducted at Vesta. Even as the team was simulating activities in the future, Dawn remained committed to its present task of thrusting with its ion propulsion system. Last month, it exceeded the greatest propulsive change in speed by any spacecraft. On July 8, it passed another milestone when its ion thrusters had yielded 10,000 mph over the course of the mission. Such an achievement may seem somewhat less noteworthy when expressed in metric units, as the project does, but 4.47 kilometers per second is just as great a velocity! Although most of Dawn?s interplanetary travel is dedicated to thrusting, the design of the flight profile included coasting during most of the week of July 19 to accomplish some other work. Each of the science instruments was activated and tested, confirming that all remain healthy and ready to reveal Vesta?s secrets to eager earthlings. A small software update was transmitted to both the primary and the backup science cameras, correcting a minor bug that would have added some complexity to the acquisition of images at Vesta. Subsequent tests showed the software ?patch? works perfectly. The spacecraft also pointed the primary science camera to selected stars as part of its regular calibration, as it has done before. In addition, the camera imaged Ceres, the dwarf planet it will study at close range in 2015. At a distance of 3.3 AU (almost 500 million kilometers, or nearly 310 million miles), the giant of the asteroid belt appears

Does anyone know if the large Gebel Kamil main mass individual with regmaglypts was found on the surface or was buried and how close to the crater? Just thinking that the shrapnel pieces would have landed on the surface after exploding from the crater a a much lower velocity than individuals...thus individuals with character/crust are much more likely to be buried deeper and perhaps many more of them may be found with detectors at a later date/expedition. Perhaps there is a strewn field of these individuals associated with the crater similar to Sikhote Alin. Any thoughts anyone?

[meteorite-list] Scientist Warns Massive Asteroid Could Hit Earth in 2182
Wow - that's only 72 years from now... Don't think I'll be around Greg S. http://www.foxnews.com/scitech/2010/07/28/massive-asteroid-hit-earth-warn-scientists/?test=faces Scientist Warns Massive Asteroid Could Hit Earth in 2182 A large asteroid in space that has a remote chance of slamming into the Earth would be most likely hit in 2182, if it crashed into our planet at all, a new study suggests. The asteroid, called 1999 RQ36, has about a 1-in-1,000 chance of actually hitting the Earth, but half of that risk corresponds to potential impacts in the year 2182, said study co-author María Eugenia Sansaturio of the Universidad de Valladolid in Spain. Sansaturio and her colleagues used mathematical models to determine the risk of asteroid 1999 RQ36 impacting the Earth through the year 2200. They found two potential opportunities for the asteroid to hit Earth in 2182. The research is detailed in the science journal Icarus. The asteroid was discovered in 1999 and is about 1,837 feet (560 meters) across. A space rock this size could cause widespread devastation at an impact site in the remote chance that it hit Earth, according to a recent report by the National Academy of Sciences. Scientists have tracked asteroid 1999 RQ36's orbit through 290 optical observations and 13 radar surveys, but there is still some uncertainty because of the gentle push it receives from the so-called Yarkovsky effect, researchers said. The Yarkovsky effect, named after the Russian engineer I.O. Yarkovsky who proposed it around 1900, describes how an asteroid gains momentum from thermal radiation that it emits from its night side. Over hundreds of years, the effect's influence on an asteroid's orbit could be substantial. Sansaturio and her colleagues found that through 2060, the chances of Earth impacts from 1999 RQ36 are remote, but the odds increase by a magnitude of four by 2080 as the asteroid's orbit brings it closer to the Earth. The odds of impact then dip as the asteroid would move away, and rise in 2162 and 2182, when it swings back near Earth, the researchers found. It's a tricky orbital dance that makes it difficult to pin down the odds of impact, they said. The consequence of this complex dynamic is not just the likelihood of a comparatively large impact, but also that a realistic deflection procedure (path deviation) could only be made before the impact in 2080, and more easily, before 2060, Sansaturio said in a statement. After 2080, she added, it would be more difficult to deflect the asteroid. If this object had been discovered after 2080, the deflection would require a technology that is not currently available, Sansaturio said. Therefore, this example suggests that impact monitoring, which up to date does not cover more than 80 or 100 years, may need to encompass more than one century. By expanding the timeframe for potential impacts, researchers would potentially identify the most threatening space rocks with enough time to mount deflection campaigns that are both technologically and financially feasible, Sansaturio 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

Re: [meteorite-list] Meteorite 20 Questions - Answer and Share if you Dare. :)
To answer my own questions : 1) When did you start collecting? (how long ago) A little over 4 years ago. 2) What first interested you about meteorites? I have always been an avid amateur astronomer, so after years of observing objects in space, I wanted to own a few. 3) What was your first meteorite purchase, and from whom? A handful of NWA 4293 pebbles from Bob King. 4) How many meteorites or localities do you currently have in your collection? About 100 localities and about 1000 meteorites. 5) If you had to know for insurance purposes, what do you value your entire collection at? - in dollars - ballpark figure OK, or just say none of your business. I've never sat down and calculated the value, but I'd guess it's worth a few thousand dollars. 6) What is your favorite meteorite and why? A 110g oriented uNWA with nice crust and a pleasing shape. I've had this stone since my first few months of collecting and I just love how it looks. It's shaped like a twinkie - Tallahassee from Zombie Land would be tempted to eat it. 7) Have you ever found a meteorite in the field? No, although I have found a couple of convincing meteorwrongs. 8) Did you ever get the deal of a lifetime on a meteorite? If so, what was it? Yes, but I am not at liberty to discuss it. 9) Did you ever go through the ordeal of a lifetime to obtain a meteorite? If so, please explain. No. 10) Have you ever consumed meteoritic material? (If so, how or under what circumstances?) Yes. I have eaten and drank - NWA 998, NWA 482, NWA 4734, SAU 005, Murchison, Tagish Lake, NWA 6026, and Allende. I was trying to gain telekinesis, the ability to fly, invisibility, or some other super-power. All but the Allende were consumed in a beverage. The Allende was snorted, accidentally, while trying to detect an aroma in a baggie of fragments. I have probably consumed more carbonaceous chondrite than any person on Earth and it's likely that my gastro-intestinal tract is contaminated with nanodiamonds. 11) Does your spouse share your meteorite passion, is ambivalent towards it, or resents it? She does not collect, but she fully supports my obsession and is working on some meteorite-related artwork that will be offered on my website in the future. 12) Have you ever let a bill go unpaid or late to buy a meteorite? Yes. I have intentionally over-drafted my bank account more than once to purchase meteorites. 13) A perfectly oriented, fully crusted, baseball-sized, lunar meteorite crashes through your roof and lands in your lap while you are reading this. It's the most gorgeous aesthetically-superior specimen you have ever seen - like Lafayette, but better. It legally belongs to you. What do you do with it? I'd have it classified. Then, I put the meteorite on a loaner program to various schools and institutions, with the condition that the meteorite is never cut or altered in any way. I would have a mold made and sell casts of the meteorite - like the Venus Stone. 14) Statistics have caught up with someone. Anne Hodges will no longer be the only documented person to be struck by a falling meteorite. Assuming the next person struck could be anyone and you could pick that person, who would it be? (silly answers only, nothing mean or political) Me - assuming I am not permanently disabled or killed. I would have it classified. Then, if the stone was not aesthetically-pleasing or a rare type, I would slice up half of it and sell the slices. I would keep the biggest endcut for myself. 15) You are awarded the honor of selecting one specimen to keep from any meteorite collection in the world. What would it be? This is a tough one. Probably the Willamette iron or the Tucson Ring. I would erect a meteorite museum around the specimen. 16) Have you ever sold or donated your entire collection, and then had to rebuild it? Yes, twice. Both times due to medical bills. I am currently building my third collection. 17) Summarize what you think about tektites in one sentence. Tektites are fascinating objects that have an allure that is different from meteorites, but no less interesting because their exact origins are still under some debate. 18) Which do you prefer - thin sections, whole specimens, slices, or endcuts? Whole stones. 19) Do you collect meteorwrongs? Yes, but only the very unusual ones or ones I have found. 20) Have you ever dropped a tiny crumb of a rare meteorite and lost it? Yes, several times. Right now, there is a piece of Ensisheim in my carpet somewhere. On 7/28/10, Galactic Stone Ironworks meteoritem...@gmail.com wrote: 1) When did you start collecting?

Re: [meteorite-list] Meteorite 20 Questions - Answer and Share if youDare. :)
15 months ago. Newbie! A picture I saw in a newspaper of Dr. Donald Brownlee of NASA holding NWA 5000 over his head with both hands and a big smile on his face. I bought my first meteorite from Robert Cucchiara (Meteorite Madness)in May of 2009. A triple cut and etched 2.7 kilo Campo with beautiful even regs and a couple of unusual troilite inclusions. It just jumped out of the monitor and said pick me! pick me!. One hundred and fifty six. I had to go count them just now. I think some must have mated. Probably a little Fukang going around the meso drawer. I don't mind talking money. It seems popular to do so today. I know how much I spent to the penny for those I purchased, and I can guess as to the value of the few I have received as gifts, and then there is the big chondrite I found which was just appraised. Probably, somewhere between $35,000 and $40,000 in acquisition, so the retail value would, I trust, be higher. A 2.1 gram crusted Nakhla individual with it's original British Museum collection card and release papers that has been keep unmolested-molested in a sterile container accompanied by an attribution letter from another major institution. It's my favorite because I'm hoping one night little green aliens will crawl out of it. Did I! Last May 5th. I went hunting with Sonny Clary in Pahrump Valley 45 minutes from my house in an area he said he had been working for over six years. Stepped out of the truck and limped a couple of hundred yards out into the desert and tripped over a 29 pound LL6 chondrite sticking four inches out of the sand. It was my first find. It turned out to be the largest individual stone meteorite found in Nevada. The Nakhla described above. No ordeals. It has all been a most pleasant experience except for one bump caused by a sobering lack of judgement. Yes. When I set about to polish the half of the big chondrite I found, I got my face right up on it as I was using the 600 grit and didn't realize I was breathing the particles until I coughed and sneezed black soot the next morning. The Countess, who generally eschews any activity I engage in, likes meteorites and the people associated with them. It might have something to do with that gorgeous Lapis Lazuli necklace a Moroccan made for her in Tucson. Not yet...but I can see it in my future. Pick it up with nitrile gloves and put it in sterile container. Pick up all the house debris and store it in bags by type. Call Allstate. Call the firm of Brownlee, Irving, Bunch and Hupe'. Me. No. Say again? I haven't studied enough specimens to have developed a preference. I'm sort of omnivorous at this point in my education. Unintentionally. Yes. I bought 4 mg of original Shergotty and when I opened the membrane box to look at the little Bessy specks under the scope they just flat disappeared. I discovered membrane boxes are like minature trampolines. I hope everyone who read these answers knows how happy I would be if they brought a smile, or two.

Re: [meteorite-list] Scientist Warns Massive Asteroid Could Hit Earth in 2182
Wow what a sham(e). A friend asked me about this earlier today but he cited a British rag. I told him that the British tabloids still report this sensationalistic crap every so often but the media in the US has figured out to ignore it. Well at least most of them have. A quick explanation: When we observe an asteroid, there is some uncertainty in our observations so while we get a good handle on the orbit, the orbit isn't exactly known to a precise amount. As such, there are often a number of similar orbits that satisfy the set of observations of the object we have on hand. There are scientists at JPL and elsewhere who's job it is to determine which NEOs will come close to the Earth. During their calculations they run all the possible orbits that satisfy the observations and determine which objects have possible orbits that intersect the Earth, when the Earth is at that intersection. These objects that have such a possible orbit are then referred to as Virtual Impactors or VI for short. The way we reduce this uncertainty of the orbits for a given object is to re-observe it over time. As we continue to obtain additional observations the number of possible orbits that satisfy all of the observations gets smaller until we come to an orbital solution that is most likely the one that the object actually is in. When an object has been determined to be a VI that alerts observatories around the world to obtain additional observations of this object. NASA JPL have a page on the NEO Program website ( http://neo.jpl.nasa.gov/ ) that is updated daily as new observations come in and get folded into the dataset. It is the Impact Risk page at: http://neo.jpl.nasa.gov/risk/ If you visit the page you'll see information on the object in question, but you'll also note that there are other objects that are also of interest, Watch it every day and you'll see impact probabilities for any given object rise and fall, with new ones appearing as they are discovered and others dropping off the list entirely as more observations come in and the orbits become more refined. My advice is unless you hear of a 100% chance of impact, ignore the story. The media is just wasting your time by making a story out of something that is not news...

The asteroid, called 1999 RQ36, has about a 1-in-1,000 chance of actually hitting the Earth, but half of that risk corresponds to potential impacts in the year 2182, said study co-author María Eugenia Sansaturio of the Universidad de Valladolid in Spain. Sansaturio and her colleagues used mathematical models to determine the risk of asteroid 1999 RQ36 impacting the Earth through the year 2200. They found two potential opportunities for the asteroid to hit Earth in 2182. The research is detailed in the science journal Icarus. The asteroid was discovered in 1999 and is about 1,837 feet (560 meters) across. A space rock this size could cause widespread devastation at an impact site in the remote chance that it hit Earth, according to a recent report by the National Academy of Sciences. Scientists have tracked asteroid 1999 RQ36's orbit through 290 optical observations and 13 radar surveys, but there is still some uncertainty because of the gentle push it receives from the so-called Yarkovsky effect, researchers said. The Yarkovsky effect, named after the Russian engineer I.O. Yarkovsky who proposed it around 1900, describes how an asteroid gains momentum from thermal radiation that it emits from its night side. Over hundreds of years, the effect's influence on an asteroid's orbit could be substantial. Sansaturio and her colleagues found that through 2060, the chances of Earth impacts from 1999 RQ36 are remote, but the odds increase by a magnitude of four by 2080 as the asteroid's orbit brings it closer to the Earth. The odds of impact then dip as the asteroid would move away, and rise in 2162 and 2182, when it swings back near Earth, the researchers found. It's a tricky orbital dance that makes it difficult to pin down the odds of impact, they said. The consequence of this complex dynamic is not just the likelihood of a comparatively large impact, but also that a realistic deflection procedure (path deviation) could only be made before the impact in 2080, and more easily, before 2060, Sansaturio said in a statement. After 2080, she added, it would be more difficult to deflect the asteroid. If this object had been discovered after 2080, the deflection would require a technology that is not currently available, Sansaturio said. Therefore, this example suggests that impact monitoring, which up to date does not cover more than 80 or 100 years, may need to encompass more than one century.

[meteorite-list] 1999 RQ36 V.I.
Hi Richard/List, I just added three more positions for this V.I. taken from Haleakala on September 12, 2005. The observations are bracketed by a pair of positions from Pulkovo taken on 9/10 and four more on 9/13 from Catalina Sky Survey, so I don't expect the impact probabilities to be altered much by my new positions. I note that there is a triplet of images from 2/7/2006 taken by Spacewatch that ought to be sensitive enough to see 1999 RQ36. It would be very close to the bottom center of the frame (and quite possibly just off the frame in some or all of the images). The other Spacewatch triplet to check is from 12/27/2005 -- the NEA is definitely in the field of view of the camera; the only question is whether it's bright enough at magnitude 21.4 to be detectable. --Rob -Original Message- From: meteorite-list-boun...@meteoritecentral.com [mailto:meteorite-list-boun...@meteoritecentral.com] On Behalf Of Richard Kowalski Sent: Wednesday, July 28, 2010 3:52 PM To: Meteorite List Subject: Re: [meteorite-list] Scientist Warns Massive Asteroid Could Hit Earth in 2182 Wow what a sham(e).

The asteroid, called 1999 RQ36, has about a 1-in-1,000 chance of actually hitting the Earth, but half of that risk corresponds to potential impacts in the year 2182, said study co-author María Eugenia Sansaturio of the Universidad de Valladolid in Spain. Sansaturio and her colleagues used mathematical models to determine the risk of asteroid 1999 RQ36 impacting the Earth through the year 2200. They found two potential opportunities for the asteroid to hit Earth in 2182. The research is detailed in the science journal Icarus. The asteroid was discovered in 1999 and is about 1,837 feet (560 meters) across. A space rock this size could cause widespread devastation at an impact site in the remote chance that it hit Earth, according to a recent report by the National Academy of Sciences. Scientists have tracked asteroid 1999 RQ36's orbit through 290 optical observations and 13 radar surveys, but there is still some uncertainty because of the gentle push it receives from the so-called Yarkovsky effect, researchers said. The Yarkovsky effect, named after the Russian engineer I.O. Yarkovsky who proposed it around 1900, describes how an asteroid gains momentum from thermal radiation that it emits from its night side. Over hundreds of years, the effect's influence on an asteroid's orbit could be substantial. Sansaturio and her colleagues found that through 2060, the chances of Earth impacts from 1999 RQ36 are remote, but the odds increase by a magnitude of four by 2080 as the asteroid's orbit brings it closer to the Earth. The odds of impact then dip as the asteroid would move away, and rise in 2162 and 2182, when it swings back near Earth, the researchers found. It's a tricky orbital dance that makes it difficult to pin down the odds of impact, they said. The consequence of this complex dynamic is not just the likelihood of a comparatively large impact, but also that a realistic deflection procedure (path deviation) could only be made before the impact in 2080, and more easily, before 2060, Sansaturio said in a statement. After 2080, she added, it would be more difficult to deflect the asteroid. If this object had been discovered after 2080, the deflection would require a technology that is not currently available, Sansaturio said. Therefore, this example suggests that impact monitoring, which up to date does not cover more than 80 or 100 years, may need to encompass more than one century. By expanding the timeframe for potential impacts, researchers would potentially identify the most threatening space rocks with enough time to mount deflection campaigns that are both technologically and financially feasible, Sansaturio 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 __ 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

Greetings, Mike and all, 14) Statistics have caught up with someone. Anne Hodges will no longer be the only documented person to be struck by a falling meteorite. Assuming the next person struck could be anyone and you could pick that person, who would it be? (silly answers only, nothing mean or political) The Mbale fall, struck a boy in the head (small stone and no injury) and that is documented and there are a few others. Maybe Michael Blood or someone else could offer other examples. I can' think of any at the time being.

It has been frequently considered for an asteroidal mission (including Osiris) as it is very easy to reach (low delta-v). We could go kick its tires...

Paradoxically, while the odds of an impact go up, so does the uncertainty of any particular outcome. It's not a party we'd want to miss the invitation to, as the impact energy is 2700 Megatons. As for waiting until the probability is 100%, Richard, you have to realize that to many people that means waiting until it's a week away. That's not the message we want to send, is it? (Keep that funding coming.) NASA put 1999 RQ36 on the Sentry Risk page at #2, trailing long time favorite 1950DA: The second object, (101955) 1999 RQ36, currently has non-zero impact probabilities on numerous occasions during the years after 2165.

As for cumulative probabilities, nothing in this kind of orbit persists for more than a few million years, maybe ten million years, so the probability that it hits either the planet whose orbit it crosses or, less likely, an object in a similar orbit is, in the long term, always 100%. We, however, are just going to hope that the folks up in 2150 have a better handle on it than we do, aren't we? (I include an exception to this last crack for Rob Matson and you, of course.)

A friend asked me about this earlier today but he cited a British rag. I told him that the British tabloids still report this sensationalistic crap every so often but the media in the US has figured out to ignore it. Well at least most of them have. A quick explanation: When we observe an asteroid, there is some uncertainty in our observations so while we get a good handle on the orbit, the orbit isn't exactly known to a precise amount. As such, there are often a number of similar orbits that satisfy the set of observations of the object we have on hand. There are scientists at JPL and elsewhere who's job it is to determine which NEOs will come close to the Earth. During their calculations they run all the possible orbits that satisfy the observations and determine which objects have possible orbits that intersect the Earth, when the Earth is at that intersection. These objects that have such a possible orbit are then referred to as Virtual Impactors or VI for short. The way we reduce this uncertainty of the orbits for a given object is to re-observe it over time. As we continue to obtain additional observations the number of possible orbits that satisfy all of the observations gets smaller until we come to an orbital solution that is most likely the one that the object actually is in. When an object has been determined to be a VI that alerts observatories around the world to obtain additional observations of this object. NASA JPL have a page on the NEO Program website ( http://neo.jpl.nasa.gov/ ) that is updated daily as new observations come in and get folded into the dataset. It is the Impact Risk page at: http://neo.jpl.nasa.gov/risk/ If you visit the page you'll see information on the object in question, but you'll also note that there are other objects that are also of interest, Watch it every day and you'll see impact probabilities for any given object rise and fall, with new ones appearing as they are discovered and others dropping off the list entirely as more observations come in and the orbits become more refined. My advice is unless you hear of a 100% chance of impact, ignore the story. The media is just wasting your time by making a story out of something that is not news... But then again that does seem to be the business they

Usually a change in odds means only that the ellipse of uncertainty has necessarily become larger. Paradoxically, while the odds of an impact go up, so does the uncertainty of any particular outcome. Yes at first, but this isn't because the encounter ellipse grows. It usually means that the ellipse become more constricted, but shifts to a more specific part of the globe. Additional observations constrain the ellipse even more, but shift it beyond one earth radius. It's not a party we'd want to miss the invitation to, as the impact energy is 2700 Megatons. As for waiting until the probability is 100%, Richard, you have to realize that to many people that means waiting until it's a week away. That's not the message we want to send, is it? (Keep that funding coming.) Of course, and obviously the funding question is not missed on me. However, no one is served by sensationalistic reporting. A realistic approach is to continue optical and radar observations as the orbital mechanics allow, and then fund and launch the OSIRIS-Rex sample return mission. In this case having a spacecraft there will do more to confirm or exclude the impact threat. If it is confirmed no later than 2022, we'd have 175 years to determine what to do to avert an impact and then actually go and do it.

Webb The main point of what I wrote was not to discount any and all threats, including the minor threat that (101955) 1999 RQ36 potentially poses. Instead to offer an opinion (common in the field) that the media makes much too much about impact threats that almost always disappear rapidly. We've seen many times in the past that even before the story makes the rounds in the media, the threat has been excluded. My advice still holds; If you see something about an impact threat in the general media and it is anything less than a 100% certain. Grabs some drinks, snacks and pop Deep Impact in the DVD player. It is better than the crap ball Armageddon, but not by much. Better still, forget both of them and go have some adult fun with your partner. THAT is a much better way to spend the time!

Re: [meteorite-list] Scientist Warns Massive Asteroid Could HitEarthin 2182
List, Stuart, An eight-mile complex crater with a depth of about a half-mile. Will take 100% casualties out to about 35 miles and 70% casualties out to 60 miles. High-speed ejecta 1 cm and up will reach out to about 100 miles. Within the inner 75-mile-diameter circle, expect the destruction of almost everything and the death of almost everybody. Even at 60 miles away, the fireball will deliver about 4 megajoules per square meter for about 3.5 minutes, enough to produce deep third degree burns, and cause trees and grass to ignite, as well as wood and part-wood structures. Masonry structures would collapse from the overpressure; steel structures would survive best. An ocean strike would form a smaller crater in the seafloor but the thermal effects would be about the same (actually a little worse). The tsunami would be between 250 and 450 feet high. It would be world-wide, reach far inland in some areas, and would likely circle the globe more than once. Either a land or sea strike would likely result in comparable damages. Numbers would depend on the population and structural density of the area. Middle of the Sahara? Thousands. South China Coast? Tens of millions. Highly unlikely that any of the materials you might gather after the region of the crater stopped glowing would be part of the impactor, almost all of which would vaporize.

Sterling, With the understanding that the impactor is of the size you described in your last. Could there be significant property damage and human casualties outside the 100 mile diameter from the fall of matter propelled to great heights and trajectories? Is it plausible that large quantities of ejecta could be propelled into low earth, rapidly decaying orbits and re-enter to cause significant secondary impact damage vicariously over the earth? Do you think some material could escape the earth's gravity to become meteoroids? Count Deiro IMCA 3536 -Original Message- From: Sterling K.
