Re: [meteorite-list] Rosetta gravity assist flyby
Hello List Larry is right. This was not a screw-up of any person or group, they performed diligently within the given parameters. It could be called though, and I think Larry would agree, a mild screw up of the system. There should be heliocentric elements updated as there are Earth orbital elements. This problem has been going on for some time. Back in the 1970's , when the Satellite Situation Report was a distributed printout, it listed heliocentric objects as merely Heliocentric Orbit. I wrote to the guy in charge for more specifics. The letter came back listing every object I inquired about, with simply the words Heliocentric Orbit beside it. Certainly active heliocentric spacecraft such as Rosetta should be right there with elements. I suspect there is an additional problem. I cannot imagine the DOD software/database did not know Rosetta was coming in. But the walls of secrecy are up, and the phone lines are therefore down. It used to be there was a lot of scientists doing a lot of secret work who were also active publishing academic work. They would instantly know. But this is increasingly not the case.

These are hard-working dedicated people, most of whom I have known for 20-30 years. I do not know all of the details, but when a discovery is made, the discoverers have access to a very large database of Small Solar System Bodies (asteroids and comets). Generally, things in orbit around the Earth have distinct enough orbits so that they are easily recognized. Not so for objects in heliocentric orbits (orbiting the Sun). In this case, an object was seen that appeared to be a Near-Earth Object that was about to make a close approach to the Earth and for which the database did not have the orbital elements. Thus, it was at first considered to be a new discovery. There are nearly 500,000 known asteroids (many with poorly known orbits) and about 5000 new ones are being discovered every month! Maintaining this database is not an easy task. Obviously, someone fairly quickly realized that this was not an asteroid, but Rosetta, but not before the alert went out for astronomers to make observations. The system worked! What did not work, as was pointed out by the Minor Planet Center, was that unless there is someone who is in a position to provide them with the orbital elements of Rosetta, there is no way that they can put this into their database. This is where the system failed. Actually it is impressive that the Catalina Survey people did see this incoming asteroid and shows how well they are covering the sky in order to locate any asteroids heading toward the Earth. However, Doug, Pluto and the IAU decision is another story that we should discuss over beers sometime.

Re: [meteorite-list] Rosetta gravity assist flyby
Hi Sterling, et al.: The asteroid (Rosetta) was discovered near midnight on November 7 and was confirmed the next night at 2 other sites. I did a calculation of size vs magnitude for the asteroid at discovery. Its H magnitude (how bright it would be at 1 astronomical unit, 1 AU, from the Earth) was 26.3. That would make it 23 meters in diameter with a 10% reflectivity (gray). The darkest asteroids reflect 5% of the light the hits them which would give a diameter of about 30 to 35 meters. At the time of discovery, it was 0.04 AU from the Earth (about 6,000,000 km) was magnitude 19.7 (about 1,000,000 times fainter than the faintest stars one can see with the naked eye) and was moving at a little less than 2 arc-minutes a day (mostly north to south). The diameter of the Moon is 30 arc-minutes (1/2 degree) for comparison. It turns out that the main belt asteroid Ceres was in the same area of the sky and was moving about 1/2 as fast north to south, but 15 times faster west to east at this time. Why the difference? Ceres is moving in its orbit around the Sun while Rosetta was aiming right at the Earth (nearly so), so even though is was much closer to Earth, it was going almost directly toward us! (if an object is getting brighter but with no apparent motion, duck!) The whole idea behind discovering Earth-approaching asteroids is to find them not when they come by the first time (not much you can do about them) but to get an early warning for when it might be coming by the next time, as in the case of Apophis. For comparison, I think that Apophis was moving at several degrees a day at the time of discovery. At that point you have a chance to do something about it (beyond just running for cover). So, to answer Sterling's question, VN84 was not discovered because of its fast motion OR brightness, but more for how slow it was moving west to east relative to its north-south motion! I will try to track this down. Larry On Mon, November 12, 2007 10:53 pm, Sterling K. Webb wrote: Hi, Larry, Doug, and other members of the Target Population, While my first reaction was to be pleased: There's something re-assuring about the notion that we could detect a potential impactor, even if we didn't immediately recognize that it's one of ours! I'm beginning to reconsider. The MPC Circular was Nov. 8th, so the detection would seem to have been the night of Nov. 7-8, or since that seems to be cutting things close, perhaps Nov. 6-7. But the first we knew of the potential event was Nov. 8th. The flyby is 20:57 UT on Nov. 13th, which for the US is the early morning hours of the 14th. That means that effectively there was 5.5 days of lead time for a potential impact. When we thought it was a small, dark (and hence unreflective) asteroid, it was estimated to be a 20-meter object (instead of a small shiny spacecraft) which, if it had stuck the Earth's atmosphere, would not have survived the encounter and would have been no threat. (Or not, if stone, it's about 10,500 tons, with an airburst of a trivial 150,000 tons of TNT.) It would interesting to know if 2007 VN84 was detected because of its brightness or because of its high proper motion. If it was because of brightness, we would have 11 days of warning for a 40-meter object, 23 days of warning for a 80-meter object, 47 days of warning for a 160-meter object... That last one, the 160-meter stone, weighs in at 5,120,000 tons, and I, for one, am willing to take that seriously (75 MegaTons of TNT and a one-and- a-half mile crater 1500 feet deep). OK, I've got 47 days. What do I do? Practically, I think the only thing that I could do is to calculate exactly where is a good place to watch the show when it hits. It's probably significant that the CSS (Catalina Sky Survey) was the one to catch it; in 2005 they found the greatest number of NEO's of all the searchers. Their methodology, as I understand it, is based on detection by large proper motion, but the object has to be bright enough to be noticed first. A really dim object shifting its relative position rapidly wouldn't get caught... until it brightened. Our problem (as a species and civilization) is that we're still in the phase of trying to find all those sneaky potential impactors. We haven't been promoted to the grade level where all we have to do is keep track of them and roll out the laser cannons in case of emergency! In this event, however, we have encountered the first known occasion where part of the problem fell under the jurisdiction of the keeping-track department (you know, the one we don't have yet). And, by pinpointing that problem, I think we've made another advancement, assuming we do something about getting that department. Sterling K.

[meteorite-list] Naming the Universe
Hi Larry, Firstly, this post is intended to be in compliance with IAU's MPC which information on names, designations, orbits, etc., are the intellectual property of MPC and may not be shared openly in public strict policy except: Selected information extracted ... may be occasionally (NOT regularly) used ... actual quoting of no more than one or two sentences (or paraphrasing) ... reference to the source of the information is acknowledged...Specifically, circulars must not be redistributed to Usenet newsgroups or to e-mail lists... [I interpret the selected extractions (but not regular extraction, nor general circular redistribution) to be permitted on the met-list]. This policy is needlessly restrictive in my opinion. If the Meteoritical Society had the same policy, commercial use (even one extracted statement posted here, and most all of our websites would be infringing by using any classification information, for example. David's site, without special permission, would be a super offender! For reasons we can imagine, Proposed Asteroid name Roberthaag was refused to be allowed by the MPC as a name. This gives me a great appreciation for the Nomenclature Committee of the Met-Soc and the ability of scientists to manage and work with non-professionals and the public. Sometimes we don't appreciate the liberties we are given! OK: In 1999, when Pluto was actually the EIGHTH planet: http://www.cfa.harvard.edu/mpec/J99/J99C03.html : Next month, we shall pass #10,000 in what is a collection of small objects ... It is also very important to affirm that there is absolutely no implied demotion...It has been traditional to have a special celebration with each thousandth numbering...It has been traditional to have a special celebration with each thousandth numbering. This honor was thus tendered. True? Similar honors given at round numbers (Minor Planet Circular 19342?): Asteroid #4,999 was named MPC by the MPC: Named by the Minor Planet Names Committee for the Minor Planet Circulars... The abbreviation also honors the Minor Planet Center, which operates through IAU Commission 20 to issue the Circulars. The milestone Asteroid #5,000 was then celebrated by naming it IAU by the MPC, to honor the International Astronomical Union. By some induction, twice as important as it would have been 10,000 Pluto?! The legislating of extraterrestrial real estate that contributed to the disgust felt by the entire world seeing the day the image of the fatherly respected astronomer, and Clyde too, were plutoed on a greasy skewer followed at the Pluto meeting. Asteroid (110,000) Vendreuncanardàmoitié? ...Just a quick view of the forest without seeing the oaks, elms and elders. Last month, the public was told in a press release that asteroid Number 100,000 (OK minor solar system body) was designated Astronautica. The chimeric astronomer stereotypes have thankfully returned as the kind and corny professor image we love, via being vested as the sole authority to name and rename the Solar System: Because 100,000 meters altitude is where space begins. This is great news. According to the IAU and Harvard, the MPC committee decided this honor for the 1 mile in diameter typical lump (that one imagines also could have been Pluto's number). Astronautica means and was chosen because: Typically the discoverer names the asteroid, but the committee sometimes takes the initiative for special numbers, explained Marsden. October 4, 2007 was an important anniversary, and we felt it was right to recognize it this way. We wanted a name with a broad international appeal, so we chose 'Astronautica,' which comes from the Latin for 'star sailor.' Ref: http://www.cfa.harvard.edu/press/2007/pr200723.html BTW, I would think Astronautica comes from the Greek astron and nautes and we have Latinized the Greek with ica it to agree with IAU policy. and Kosmonautica would have been preferable given the Sputnik tie-in and that these first 50 years have been in the kosmos, but not yet the stars (astros)...but twithout any personal auspices for sure :-) And back in 1999, asteroid 10,000 was named when Pluto himself rejected being one of the myriad. MPC then playfully named Asteroid number 10,000 Myriostos. That's from Greek for myriad, ten thousand things. Paraphrasing: You should have taken the 10,000 when we offered it to you, tough luck, serves you right. was the pith for several unprofessional participants during the Pluto debates of 2006. Does the gestalt strike you as somewhat arrogant and give no doubt why the consternation and sullied generalized images have materialized in the public? I think that recent memo was unprofessional because: (1) No one at the authority took responsibility, making AU Tomatic sign it though an opinionated and aggressive editorial of blame, not automated data. (2) The authority on naming then went on to blame others for not doing the

http://www.esa.int/esaCP/SEMC20VOM8F_index_1.html Rosetta swing-by a success European Space Agency 13 November 2007 An important milestone has just been accomplished as Rosetta successfully swung by Earth at 21:57 CET. The spacecraft will now be catapulted towards the outer Solar System with its newly-gained energy before coming back to Earth for another boost. As mission operators waited for the fully automated manoeuvre to be carried out, Rosetta flew directly above 63° 46â south and 74° 35â west, at 21:57 CET (above the Pacific ocean, south-west of Chile). Rosetta whizzed past 5295 km overhead, at a velocity of 45 000 km/h (12.5 km/s). Europe's comet chaser has now flown a little over 3 thousand million km of its 7.1 thousand-million-km journey on its way to its destination comet 67/P Churyumov-Gerasimenko. This was the third planetary swing-by for Rosetta and its second swing-by of Earth. Science close to Earth Around closest approach, Rosetta took a good look at Earth for observations of its atmosphere and magnetosphere, imaged urban regions, and looked for meteors from space. Shortly before midnight, Rosetta will turn to observe the Moon until about 11:00 CET tomorrow, 14 November. Following this, on 15, 16, 18 and 20 November, Rosetta will observe the Earth-Moon system from a distance, on its outbound trajectory. Scientists are now eagerly awaiting some of the first data to become available during the course of the night. Rosetta will be back in our neighbourhood, and will swing by Earth for the last time in November 2009. But before that, as it crosses the asteroid belt, Rosetta will grab the opportunity to study asteroid Steins during a fly-by in September 2008. Tune in early tomorrow morning: we will be publishing pictures and results as soon as they become available, throughout the day on 14 November.

[meteorite-list] Mars Exploration Rovers Update - November 12, 2007
http://marsrovers.jpl.nasa.gov/mission/status.html SPIRIT UPDATE: Spirit Continues Drive As Power Levels Decline - sol 1363-1369, November 12, 2007: Spirit has been gradually losing power, with energy levels dropping to 320 watt-hours per Martian day (100 watt-hours is the amount of energy needed to light a 100-watt bulb for one hour). Measurements of atmospheric dust, known as Tau, have been averaging 0.65. That dust level is typical of levels measuring throughout most of the mission, but power levels are lower than in previous years because of higher dust accumulation on the solar panels. (The rover estimates dust levels by measuring opacity -- the degree to which the atmosphere is impenetrable by light. During most of Spirit's mission on Mars, except during the recent dust storms, tau values have fallen between 0 and 1.) During the trek to reach the north edge of Home Plate before the next Martian winter, Spirit had time to conduct only one scientific campaign. Scientists selected a rock target nicknamed Pecan Pie (investigators are nicknaming targets on top of Home Plate for things served in bowls) for closer investigation, at a location known as Site 5. Spirit brushed Pecan Pie, took pictures of it with the microscopic imager, and analyzed its composition with the alpha-particle X-ray spectrometer. Planned measurements over the weekend included an analysis of iron-bearing minerals with the Moessbauer spectrometer before resuming the drive. The successful brush of Pecan Pie marked the first time that Spirit had used the new, two-sol brushing procedure that enabled continued use of the rock abrasion tool following the failure of the grind encoder. Spirit continued to collect images of the west side of Home Plate (known as West Valley to science team members) while advancing northward. The images are important for understanding the geology as well as for planning the hoped-for, post-winter drive to a hill known as von Braun south of Home Plate. Spirit remains healthy. On Sol 1369 (Nov. 9, 2007), plans called for Spirit to run a diagnostic of the rock abrasion tool by pointing it at the hazard avoidance camera for photo documentation while running the motor at various voltages. The resulting measurements of the spinning of the tool will provide a baseline for eventual failure of the motor and for comparison with Spirit's twin, Opportunity, on the other side of Mars. Sol-by-sol summary In addition to receiving morning instructions directly from Earth via the high-gain antenna, sending evening data to Earth at UHF frequencies via the Odyssey orbiter, measuring atmospheric dust levels with the panoramic camera, and surveying the sky and ground with the miniature thermal emission spectrometer, Spirit completed the following activities: Sol 1363 (Nov. 3, 2007): Spirit acquired pre-drive, panoramic camera images of targets known as Posole, Green Chile, and Flan, then drove 24.83 meters (84.46 feet) to Site 5 on Home Plate. The rover acquired post-drive image mosaics with the navigation and panoramic cameras. The next morning, Spirit completed a survey of rock clasts with the panoramic camera and took a mosaic of images with the navigation camera. Sol 1364: Spirit acquired images of the distant dune field known as El Dorado with the panoramic camera, and after communicating with the Odyssey orbiter during its overhead pass, measured atmospheric argon with the alpha-particle X-ray spectrometer. In the morning, Spirit completed a full-color, systematic ground survey using all 13 filters of the panoramic camera. Sol 1365: Spirit spent the day recharging the battery. The following morning, Spirit searched for dust devils using the navigation camera. Sol 1366: Spirit placed the rock abrasion tool on Pecan Pie and acquired a mosaic of images known as the West Valley View with the panoramic camera. The next morning, the rover took spot images of the sky with the panoramic camera and acquired movie frames in search of dust devils with the navigation camera. Sol 1367: Spirit acquired another mosaic of images of West Valley View with the panoramic camera. In the morning, Spirit acquired full-color images, using all 13 filters of the panoramic camera, of the rover's tracks. Sol 1368: Spirit conducted scientific studies of Pecan Pie, including brushing the surface of the rock target with the brush on the rock abrasion tool, acquiring stereo microscopic images of the brushed surface, and collecting 9 hours of compositional data with the alpha-particle X-ray spectrometer. The rover also acquired a mosaic of images of West Valley View with the panoramic camera. The following morning, Spirit took thumbnail images of the sky with the panoramic camera. Sol 1369 (Nov. 9, 2007): Plans called for Spirit to run diagnostic tests of the rock abrasion tool and acquire a mosaic of images of West Valley View with the panoramic camera.

[meteorite-list] Campbell, Planetary Society urge Congress to save Arecibo
http://www.news.cornell.edu/stories/Nov07/arecibo.congress.html Chronicle Online e-News Campbell, Planetary Society urge Congress to save Arecibo http://www.news.cornell.edu/stories/Nov07/arecibo.congress.html Nov. 9, 2007 By Lauren Gold [EMAIL PROTECTED] As part of a continuing effort to save the Arecibo Observatory from fatal budget cuts, Cornell astronomy professor Donald Campbell testified before Congress, Nov. 8 on the importance of the telescope's radar system for the identification and tracking of potentially hazardous near-Earth objects (NEOs). On the same day, the Planetary Society, a space advocacy organization co-founded by the late Cornell astronomer Carl Sagan, issued a statement to Congress in support of the planetary radar system at Arecibo and its research. If some object out there really is on a collision course with Earth, and we don't have the means to track it properly, the statement said, the price we would pay would be astronomical. The observatory's future has been in jeopardy since November 2006, when an advisory panel to the Division of Astronomical Sciences at the National Science Foundation (NSF) recommended that its operating funds be reduced to $8 million from $10.5 million over three years and then halved to $4 million in 2011. If the observatory failed to raise funds from external sources to make up the difference, it would be forced to close. In October, U.S. Rep. Luis Fortuño (R-Puerto Rico) and Dana Rohrabacher (R- Calif.) introduced legislation in the U.S. House of Representatives to ensure continued operation of Arecibo. Campbell was among five scientists to address the Subcommittee on Space and Aeronautics of the House Committee on Science and Technology. He discussed the role of Arecibo's radar system, which is one of only two high-powered radars in the world used for studying solar system bodies, on characterizing NEOs and their potential threat to Earth. Arecibo's radar is over 20 times more sensitive than its counterpart, NASA's Deep Space Network 70-meter antenna at Goldstone, Calif., Campbell noted. But because it is less maneuverable, both systems are vital and complementary. The more we know about NEOs in general and about specific ones that pose a threat to Earth, the easier it will be to design effective mitigation strategies, said Campbell. NEOs form a very diverse population encompassing a large range of sizes, shapes, rotation states, densities, internal structure and binary nature. Radar provides the best way to survey and categorize such objects, he said. For an object that we know poses a direct threat to Earth, radar can provide vital input to mitigation planning, including planning for any precursor space mission. Campbell also noted Arecibo's unique role in supporting research in radio astronomy, radar planetary studies (including the study of NEOs) and ionosphere physics, as well as in education and outreach activities. If the Arecibo radar system is decommissioned ... a tremendous amount of basic science related to NEOs and other solar system bodies would be lost, he said. In its concurrent statement, the Planetary Society called the Senior Review recommendation a misguided attempt to free up funding for new projects that do not yet exist.

Hi, I'm a science teacher and have been collecting meteorites for decades and have amassed a wonderful teaching collection. The one thing I haven't done yet is search for my own meteorites and I'd like to do that now. I visited the White's dealer in CT and he recommended the MXT or DFX models and I wondered what people thought of those models compared to the more highly recommended Gold Master model. It doesn't appear that there is much difference between models but I'm sure there is some. All models seem capable of detecting iron and nickel as well as other minerals found in meteorites. I'd like to get the best model I can afford for the job so if I don't find anything I don't have to blame it on the detector. I majored in Geology and did quite a lot of field collecting and work and am really looking forward to trying my hand at this. I also will be traveling to Tucson, AZ to visit relatives in a few months and hoped that if you have searched for meteorites near Tucson you might be willing to e-mail me about your experiences and share location info. and/or advice. Thanks for any help you can give! Jon Wallace [EMAIL PROTECTED] __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Metal detector and Tucson collecting advice requests
Jon get the White's GMT model! A lot of the guys I hunt with use these and they're excellent for meteorite hunting. I've seen guys pluck 1/4 gram Chondrites with these with no problem. Dealers try to pedal the MXT because it is one of the most popular detectors and it's more expensive than the GMT. It's an all around detector meaning it's designed to use for coin/relic and gold hunting. It has a lower frequency than the GMT so you probably wouldn't be able to pick up really small Chondrites with it. To learn more about detecting sign up on this forum- http://www.nuggetshooter.ipbhost.com/index.php?showforum=8 There's a lot of knowledgeable people on it that will be glad to help you get started in hunting. Hope this helps! Del --- Frederick J. Wallace [EMAIL PROTECTED] wrote: Hi, I'm a science teacher and have been collecting meteorites for decades and have amassed a wonderful teaching collection.

[meteorite-list] [OT] Leigh Anne Update
Dear Friends and Listees: Leigh Anne has been discharged from hospital and is staying with friends here in Tucson during her recovery. The heart surgery was a success and her blood pressure and pulse are normal for the first time in her life. She looked weak and tired, but was in good spirits. She will be recuperating for some time. A sincerely thank you for all the kind thoughts and emails that were sent to the List, and to me personally. I read every one of them out loud to Leigh Anne when I visited her today and she said, I feel better already! I know that your good wishes meant a lot to her. Hopefully that's a happy ending for this story.

[meteorite-list] Fw: Crater String Claim REDUX
Hi, Jerry, List, This site is Johnny Tonto of Pueblo, Colorado. He's been much discussed on the List. His craters are largely Craters of the Mind, I think. I ain't convinced, at any rate. You want more? The crater string idea, along the same lattitude is not new and not his. The problem is: they all have different ages. Whoops! The idea of a string predates that discovery. Not all those craters are craters (but most are). The Gunnison crater has been extensively debunked on the List by folks who know a) the area, and b) geology. His evidence (concerning the Gunnison crater) isn't. Oh, and he has a secret crater somewhere that he can't divulge. The crater in the news story was also a subject of discussion here. After a few days of flurry, it turned out to be a geological formation. I'd tell you all about it, except that when it turned out not to be meteoric, I promptly forgot all of it. No point in overburdening those little grey cells, is there? Sterling K.
