[meteorite-list] re: meteor velocities Hoba
Hello Jose and others I suppose that the Earth's gravitational attraction onto these = meteoroids would not account too much, on their slow, or very fast = relative velocities? No, because it is the same for both 'slow' and 'fast' objects, so their relative speed difference remains. On a slightly different matter: What would you think that, considering = its ~60 Ton mass, the great HOBA meteorite's entry velocity might have = attained on atmosphere entry? Looking at the plots in Hills Goda (Astron. J. 105, 1114) as a rough indication, it should have been not more than 15 km/s. With larger velocities it would have fragmented in smaller fragments. And why was it that most of it, did no = desintegrate to smaller fragments? Even at a lower minimum velocity of some 11 km/s, why is is that it did = not made a small hole/crater on the ground? (unless if its vestiges have = been eroded with time, bearing in mind it's estimated 80.000 yrs since = it fell to the ground). This is a point about which I've wondered too! Looking at the plots in Hills Goda (Astron. J. 105, 1114), an iron body this size should actually be in the range where it would retain some of its cosmic velocity (i.e. have impact velocities of km/s, not m/s). Was it because of a very low = velocity? (which implies an asteroidal origin) Being an iron meteorite, Hoba certainly is of asteroidal origin. Iron meteorites are fragments of the metal cores of differentiated asteroids (achondrites are the mantle materials of these). - Marco -- Dr Marco Langbroek Leiden, the Netherlands 52.15896 N, 4.48884 E (WGS 84) [EMAIL PROTECTED] http://home.wanadoo.nl/marco.langbroek -- __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] ESA's First Step Towards Mars Sample Return
http://www.esa.int/export/SPECIALS/Aurora/SEMQH0XLDMD_0.html ESA's first step towards Mars Sample Return European Space Agency 12 November 2003 What is the next best thing to humans landing on Mars and exploring the wonders of the Red Planet? The answer: touching, imaging and analysing carefully preserved samples of Martian rock in a state-of-the-art laboratory on Earth. If all goes according to plan, this is exactly what ESA's long-term Aurora programme of Solar System exploration will achieve a decade from now, when the first samples of Mars material will be sealed in a special capsule and returned to Earth for analysis. The first step towards making this great leap in human knowledge a reality was taken at the end of October with the announcement of the winners of competitive contracts for the Mars Sample Return (MSR) mission, the second Flagship robotic mission to be proposed as part of Aurora. The parallel contracts for the Phase A studies that will carry out a full mission design iteration for the MSR have been placed with two industrial teams. One team, headed by Alenia Spazio (Italy), also includes Alcatel (France), Dutch Space (Netherlands), ELV (Italy) and MDR (Canada). The other team, headed by EADS Astrium (UK), also includes Astrium SAS (France), EADS ST (France), Galileo Avionica (Italy), RAL (UK), SAS (Belgium), SENER (Spain) and Utopia Consultancies (Germany). The industrial proposals received were of outstanding quality, reflecting the enthusiasm and the commitment of the industrial teams who prepared them, said Bruno Gardini, Aurora Project Manager. Bringing Mars back to Earth As currently envisaged, the MSR will be a two-stage endeavour. First, a spacecraft that includes a return capsule will be launched in 2011 and inserted into orbit around Mars. Two years later, a second spacecraft carrying a Descent Module and a Mars Ascent Vehicle (MAV) will be launched on a similar trajectory. During its final approach to Mars, the Descent Module/MAV will be released and make a controlled landing on the pristine planet. A robotic drill will then collect a soil sample from a depth of 1½ to 2 metres and seal it inside a small canister on the ascent vehicle. Other samples of Martian soil and air may also be gathered and stored inside the canister. Carrying its precious samples, the MAV will lift off from the surface, then rendezvous and dock with the spacecraft in Martian orbit. After receiving the canister loaded with Martian rocks, the spacecraft will return to Earth with the re-entry capsule containing the samples and send it plummeting into the atmosphere. Slowed by a parachute or inflatable device, the capsule will make a fairly gentle touchdown before recovery teams retrieve the container from the landing site and deliver it to a planetary protection facility where the samples will be removed to await analysis by eager scientists. The design of the capsule will ensure that the structural integrity of the sample container remains intact, even if the parachute fails to open and a crash landing occurs. The Mars Sample Return mission is one of the most challenging missions ever considered by ESA, said Gardini. Not only does it include many new technologies and four or five different spacecraft, but it is also a mission of tremendous scientific importance and the first robotic mission with a similar profile to a possible human expedition to Mars. A number of the critical technologies required for the success of this ambitious endeavour have yet to be developed in Europe, e.g. re-entry of spacecraft arriving from at high velocity from deep space. As a preliminary stage in developing a vehicle capable of bringing back samples from Mars, it was considered necessary to develop this re-entry capability and to demonstrate its maturity as part of the Aurora programme. Feasibility studies for a dedicated Arrow mission, known as the Earth re-entry Vehicle Demonstrator (EVD), were recently announced. In the same way, testing of the complex rendezvous and docking techniques will be carried out as an experiment on the ExoMars mission, the first Flagship mission of the Aurora programme. The Phase A industrial study contracts for the ExoMars mission began in September.

Re: [meteorite-list] Ad -Rare Weekly Material Special
Hello Adam and List, NWA 1235 caught my interest earlier this year when I read the abstract you referenced. With help from a friend I was able to acquire a small specimen and construct a webpage based on information from this abstract. BTW, contrary to the statement in this abstract that only NWA 1235 and Y-82189 have been found to contain phlogopite, it was reported that the CV3 chondrite Grosnaja contains sodium phlogopite as mentioned on my website: The Bali-like mineralogy of Grosnaja includes the phyllosilicates saponite and sodium phlogopite replacing Ca-rich minerals in chondrules and CAIs. I look forward to further research results on NWA 1235. Sorry about the difficulty in linking to my page. It was only after the 5th case (that I am aware of) of somebody using my texts verbatim on their commercial website (making it a violation of the Digital Millenium Copyright Act) that I was compelled to install an HTML protector program. This is more trouble for me to use, but gives me some degree of satisfaction knowing that these vultures (as you so succinctly put it) will now have to type out the texts by hand to steal them. The page URL still appears in the address bar and you'll notice that the previous page name is now simply preceeded by protected_. I've always given permission to use my compiled texts when asked, only requesting that a credit to meteoritestudies.com be given on the page.

It is classified as an ungrouped Phlogopite-bearing Enstatite Achondrite, in other words a unique one-of-a-kind meteorite with a Total Known Weight (TKW) of only 80 grams. We were lucky to get a few grams of this material in trade for some planetary specimens so it was not an inexpensive acquisition. We are keeping the largest piece for our collection and are offering the rest. This meteorite is even odder than NWA 011, which garnered a lot of press in the last couple years after speculation it may have originated from the planet Mercury. Just like NWA 011 the parent body is unknown. It will be interesting to see where the O-isotopes place it. We were told the finder is keeping the rest in his collection so very little will be available so now may be the time to bid. We are starting all of the NWA 1235 specimens out at just .99 and will let the market decide their value. In this weeks auction we are also introducing nine never before offered meteorites. To see these just look for NEW in the title and to see this week's special look at NWA1235.

We are obviously missing a critical issue here, because the chondrules were scant, and indistinct, in fact my Ghub, at an L6 had more structure visible. It was a very dark matrix too, whereas a lot of H3s have a light matrix (ie Parnallee) How and why is KK an H3 - the native iron was sparse, and the chondrules largely invisible.

Re: [meteorite-list] Korra Korrabes
Dave: I think it also depends on which TYPE of Korra you have. I have one that was found early on and is LOADED with gorgeous chondrules and breccia fragments. Later editions of KK were very weathered and thus did not exhibit the well defined chondrules. Also, some of the pieces were actually fragments of the breccia (L5 I think?) and of course, did not show well.

Re: [meteorite-list] Korra Korrabes
There are a couple of things you might not know about Korra Korrabes. First, there are two different grades of it that were collected. The very weathered specimens are missing much of the iron due to weathering. Fresher and better preserved specimens have less weathering and fracturing and more intact metal. Second, KK is one of those meteorites that loses much of it's detail when highly polished and viewed with the naked eye. These specimens are best viewed under well-light magnification. To make the details of the specimen more visible to the naked eye, hand sand the specimen with silicon carbide paper in 220 grit or coarser range. Selma is another meteorite that exhibits this same characteristic. When highly polished, it looks nearly black and featureless. But, when prepared properly it shows a lot of chondrules.

Hoffman III doesn't have a company, or investors forhis detection system, called "Looking out for you." But hereceived a patent (U.S. No. 6,452,538), and some distinguishedastronomers say his idea is intriguing.Hoffman wants to place telescopes on the outer-space side oftelecommunications satellites where they can continuously scanthe heavens, free from cloud cover that often hampers earthboundtelescopes, to look for what astronomers call NEOs, or NearEarth Objects.The data would beam down to a ground station and be sent - fora fee - to schools or institutions or individuals who could use itto pinpoint the rocks' orbit."I can't speak for NASA, but personally I think it's a great idea ifhe can make it work," said Dan Mazenek, an aerospace engineer based at NASA'sLangley Research Center and director of a study on how best to search for large cometsand asteroids that might strike Earth."If he can get the money to put telescopes up there then I'm interested in the results,"said Lucy McFadden.McFadden was one of thirteen scientists and researchers who signed an open letter toCongress in July warning of the threat from space and urging the government to investin some kind of system to help guard against a significant hit.Hoffman is an unimposing man with a polite, professorial manner who acknowledgeswith good humor that many people might find his idea sort of, well, pie in the sky. Andhe's also realistic enough to know he'll have to make a lot of noise to get any investorsinterested."If I have to fund it myself it's not going to happen at all," he said.He believes colleges and universities without an astronomy program might be willing topay for the telescope data.And individuals could access it via the Internet, where subscription fees and advertisingmight bring in revenue."There are lots and lots of people that would buy into the idea of helping protect theEarth by signing onto a program like this," said Kelly Beatty, executive editor of Sky Telescope magazine. Whether they would pay for the privilege is another question, headded.Beatty and others also raised numerous questions about technical aspects of Hoffman'sidea.Would the telecommunications companies that own the satellites agree to the plan?Would cosmic rays interfere with the images?How exactly would the raw data be processed into pictures of the heavens?And perhaps the biggest issue: cost."We always ask, could this be accomplished from the ground?" said Neil deGrasseTyson, an astrophysicist and director of the Hayden Planetarium at the AmericanMuseum of Natural History. He was skeptical of Hoffman's plan, he said, because "it'smore expensive to do anything in space."But Tyson, who also signed the July letter to Congress, agreed there was a need to getsomething in place to identify dangerous space rocks."There is no organized effort to monitor the sky continuously," he said.Hoffman, a graduate of Wayne High School who attended the Air Force Academy andreceived his doctorate in organic chemistry from Stevens Institute, acknowledged thechallenges but welcomed any scrutiny."The more people that start paying attention to this idea, the more likely it's all going towork," said Hoffman, who spent his career working for a number of chemical companiesincluding Union Carbide before becoming a chemical industry consultant.Hoffman said the beauty of his early warning system is its relatively low cost.He estimates putting the first telescope up might fall in
