That would be pretty easy to find out with some basic equipment. Take some sort of measuring cup or some type of graduated container and measure the volume of the object (the amount by which the water level rises is the volume. If you don't have that, fill some sort of comtainer to the very top. Carefully place the object in it and captue the water that spills out. Weigh that water and calculate how much volume that weight of water would have. Either way, once you have the volume, weigh the "thing" and divide weight by volume. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Re: Dronino & Steve Schoner's meteorite anti-rust treatment.
Mike & list, I haven't seen any responses come through on this and it's a bit of meteorite lore that many might find occasion to need. I don't know anything about the Schoner post you mentioned, but last year I had a chance to go to Argentina and acquire some Campos directly from the family who's estancia includes part of the strewn field. They have recovered more than a tonne from the family garden plot! This is an extreme case, and for lesser rust you can be less aggressive. The pieces I got were very rusty. The locals coached me on cleaning them, and this approach worked very well. 1) pound all the scaly areas with a hammer. It sounds brutal, but you won't be able to mark the solid metal (remember the Tucson ring/anvil!). Only the scaling rust will flake off, and you need to get rid of it. I used my geologist's pick. The pointy end works well for getting into regmaglypts. Spend some energy at this stage. I was stuck in a field camp in the high Andes, so I pounded on my meteorites every evening for a couple of weeks. Rust everywhere! This is an outside job. 2) Immerse it in a strong sodium hydroxide solution for as long as it takes. Two weeks is common, a month is not uncommon. You will see an amazing amount of rust flakes spall off and fall to the bottom. After a couple of weeks transfer the iron to another pail and decant the lye solution onto it. When stuff quits falling off, you're done. You will lose some mass, but this story is about a real rust bucket, and anything that will come off by this process needs to come off. 3) Rinse it well. I used water, and I really think it's okay at this stage. Anything that was porous or cracked will have come off in steps 1 or 2. You need to get rid of the lye. You can deal with the water in step 4. 4) Immerse in anhydrous isopropyl alcohol for about a week. 5) Air dry, then dry in the oven under low heat, oven door cracked open for an hour or so. 6) While it's still warm (but no longer hot) treat with a rust inhibitor. The Argentines suggested simple mineral oil, which I used with fine results. A thread on the metlist a year or so ago recommended Paraloid dissolved in acetone (used for conservation of archaeological materials). Type B72 for irons, B42 for stones. Hope this helps someone out there. Cheers, Norm, squirrely as a first-grader on the day before Christmas!!!

[meteorite-list] Mars Science Laboratory: Big Wheels on A Red Planet
http://www.space.com/businesstechnology/060118_msl_wheels.html Mars Science Laboratory: Big Wheels on A Red Planet By Leonard David space.com 18 January 2006 PASADENA, California - Make way Spirit and Opportunity - big daddy is coming! The next wheels on the red planet will belong to the Mars Science Laboratory (MSL) - a huge step in how that planet is further poked, probed, and more fully plumbed for new information. MSL is a huge chunk of machinery. At liftoff in September 2009, it will carry the largest, most advanced set of instruments for on-the-spot science duties ever dispatched to the martian surface. The nuclear-powered rover is being designed to assess whether Mars ever was, or is still today, an environment able to support microbial life. On one hand, MSL closes out an intensive period of surveying Mars - while setting the stage for an aggressive agenda of future robotic Mars exploration that ultimately leads to the planting of the first footprints on the red planet. Chemist on Mars "This is a good mission to end the decade on, but also the stepping stone for the next 10 years after that," said MSL Project Manager, Richard Cook, here at the Jet Propulsion Laboratory (JPL). "It's kind of a good transition mission." Cook said the MSL team now consists of nearly 200 people, with everyone benefiting from years of plotting out the vehicle's design and how best to build and land the mega-rover. "We've looked at a lot of the technical issues and, hopefully, have our arms around a lot of them," he told SPACE.com. The still going strong, golf cart-sized Mars Exploration Rovers (MER) - Spirit and Opportunity - have often been characterized as field geologists. "MSL is like a chemist on Mars," Cook said. "From a technological point of view, people will be fairly amazed by both the size and the capability of MSL. It will certainly be able to drive circles around MER to a certain extent. Not speed wise. But from how long MSL can go every day - it will be able to do much more," he added. Single, go-it-alone rover The MSL mission, including cost of a launcher, is in the range of $1.5 billion, Cook said. Under consideration to boost the Mars Science Laboratory is either the Delta IV or the ATLAS V rocket. The primary MSL launch/arrival period is scheduled to extend from September 15 through October 4, 2009. That equates to a rover arrival period at Mars starting on July 10, 2010 and lasting until September 22, 2010. Once down on Mars in 2010, MSL is to demonstrate long-range mobility on the surface of the red planet of about 3 to 12 miles (5-20 kilometers) for accomplishing a range of exploration tasks. There will be no doubling-up on Mars like Spirit and Opportunity. MSL is a single, go-it-alone rover tipping the scales at about 1,708 pounds (775 kilograms). And that's where the Mars Reconnaissance Orbiter (MRO) - now outbound toward the red planet - will provide a big step up, Cook advised. "We're going to be able to learn much more from orbit. And I'm confident that in the end we'll pick out the best MSL landing site. If you only have one to send, you send it to the best place you can on Mars," Cook said. Plutonium-powered While the cruise to Mars, as well as descent onto the planet mirrors past missions, the landing part of MSL is new. Mars Science Laboratory is to use precision landing techniques, steering itself toward the martian surface similar to the way the space shuttle controls its entry through the Earth's upper atmosphere. In this way, the spacecraft would fly to a desired location above the surface of Mars before deploying its parachute for the final landing. Given that capability, the plutonium-powered MSL will land within a 12-mile (20-kilometer) ellipse. NASA is also considering a solar power alternative for the rover that could meet the mission's science and mobility objectives. "It's not the same mission with the solar arrays. It would have to be a conscious decision on NASA's part to say we want to change the basic parameters of the mission," Cook said. MSL's arrival on Mars will not rely on airbags. "While airbags are certainly great they have certain limitations," Cook said, explaining that the future rover package is to be lowered onto Mars via an engine-firing "Sky Crane". This never-flown-before concept will lower the upright and ready-to-roll MSL on a tether to the surface. Wringing out the risks "Obviously, the entry, decent and landing is a very big challenge. I think we're going down the path - retiring a lot of the risk in the technology. But there's still the whole validation process - and still a lot of effort ahead to make that work," Cook said. While putting all your Mars eggs in the one and only MSL basket would appear to the squeamish a risky approach, consider the Cassini at Saturn mission now underway, as well as the one and only Mars Pathfinder project that unloaded the tiny Sojourner rover onto Mars in 1997.

HOSTETLER RICHMOND TIMES-DISPATCH January 19, 2006 NASA moon rocks stolen from a parked van were tucked in a safe whose combination lock worked sporadically, says the Virginia Beach educational specialist who used the rocks to teach about space. NASA and Virginia Beach police are investigating last week's theft near Oceana Naval Air Station. One Lucite disk about 6 inches wide held three moon rocks and three soil samples weighing a little more than a paper clip, and another disk contained six meteorite samples. "I really feel bad about what happened, losing a national treasure," aerospace education specialist Rudo Kashiri said yesterday. The van's alarm sounded shortly after 3 a.m. Jan. 10, but by the time Kashiri awoke in her condo and ran outside to her driveway, someone had forced open the van's side door and snatched the moon rocks from the safe, which was bolted and welded to the van, she said. A silver suitcase, a projector and a cooler were also taken. The cooler was found nearby by police who arrived and searched the area, she said. Kashiri said the safe's lock had been troublesome lately, but she thought the safe was closed that night. "Once in a while, sometimes it would not stick [shut], and sometimes it will, and maybe this is one of the times I thought I locked it all the way and it didn't," she said. Her employer says the problem was not reported but an official is going through e-mails to see if it had been overlooked. Kashiri works for the NASA Aerospace Education Services Program, which has 32 education specialists around the country assigned to NASA centers. They visit classrooms and give teacher workshops and lectures to the public. The program is run by Oklahoma State University. After the theft in Virginia Beach, the specialists were reminded of NASA's requirements to safeguard their samples, said the program's director, Steve Marks of OSU. "They are to be under lock and key at all times," he said. Marks said he is waiting for reports on the investigation by police and NASA's Office of Inspector General before determining whether to take any action against Kashiri. Kashiri, a former teacher trained in physics, joined the edu- cational program in 2004 after working at Atlanta's Fernbank Science Center for several years. As one of three instructors at Langley Research Center in Hampton, Kashiri is scheduled to present a program in Franklin on Saturday to fourth- and fifth-graders. Instructors must follow strict guidelines for safeguarding NASA's moon rocks. They are not to leave the samples unattended and may display the samples only at NASA-approved locations. When not in use, the samples are to be secured in a vault or the safes in their vans. Most of the Apollo soil samples and moon rocks, more than 800 pounds collected by astronauts from 1969 through 1972, are still held at the Johnson Space Center in Houston. The stolen samples are uninsured and have no official monetary value, according to NASA. If the moon rocks have been removed from their containers, they lose their scientific value. Federal law prohibits private ownership of lunar samples brought back by the Apollo missions, and they cannot be legally sold. However, an unscrupulous collector might seek one illegally, says a retired NASA employee who investigated missing moon rocks given in goodwill gestures to 135 foreign nations in the 1970s. Given that the asking price eight years ago for a NASA moon rock taken from Honduras was $5 million, Joseph Gutheinz said he's concerned for the specialists' safety. "What would the average criminal do for $5 million?" said Gutheinz, now a lawyer in private practice in Houston. "The good news is that the moon rocks in this case were taken from a vehicle and not a person." Marks defended the program's policies, saying that the moon rocks stolen in Virginia Beach are the first such theft for the 28-year-old educational outreach program. A reward of $1,000 is being offered for information leading to an arrest. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] NASA Postpones Dawn Launch to 2007
http://news.yahoo.com/s/ap/20060122/ap_on_sc/asteroid_mission;_ylt=AlxalUUF6kIXy4Y6drELTmJvieAA;_ylu=X3oDMTBiMW04NW9mBHNlYwMlJVRPUCUl NASA Postpones Mission to Visit Asteroids By ALICIA CHANG Associated Press January 21, 2006 LOS ANGELES - A NASA spacecraft built to explore two of the solar system's largest asteroids won't launch this year because the space agency is dealing with cost overruns and technical issues in the project. The planned summer launch of the Dawn spacecraft has been indefinitely postponed, said Andrew Dantzler, director of NASA's solar system division. Mission managers had been ordered to halt work on Dawn last fall while the project was assessed by an independent review team, which is expected to present its findings to NASA on Jan. 27. Even if NASA gives Dawn the green light, it would take another year for engineers to finish routine testing of the spacecraft, said mission principal investigator Christopher Russell of the University of California, Los Angeles. "It's like running a relay race," Russell said. "You're on your last leg and the judges suddenly say 'Stop.' You lose your momentum." Dawn is part of a NASA program called Discovery that seeks to explore the solar system on what for NASA is considered a shoestring budget. The program includes the Stardust mission, which last week returned to Earth with samples of comet dust. Dawn, however, has suffered several setbacks, including ruptures of two of its fuel tanks during testing, forcing engineers to reduce the amount of xenon gas that will be loaded into the tanks. The project was capped at $371 million, according to Russell, and when project scientists asked for an extra $40 million last year, NASA ordered the standdown to figure out why it was going over budget. Dantzler said that while Dawn is vital to advancing knowledge of the solar system's beginnings, overfunding it would hurt other missions. "This is first-class science and we'll do everything we can to give it the go-ahead," Dantzler said in a recent interview. Dawn was supposed to be launched from Florida in June. Powered by an ion engine fueled by the xenon gas, it was to make a nine-year journey to Ceres and Vesta, located in the main asteroid belt between Mars and Jupiter. Asteroids are believed to be remnants from the solar system's formation about 4.5 billion years ago, and studying them could provide clues into how the sun and planets emerged. Previous missions to asteroids include a Japanese probe that is believed to have landed on one last year to collect samples. Dawn would be the first spacecraft to spend months orbiting two large asteroids to study them in depth. The two asteroids are believed to have formed in different parts of the solar system and to have undergone different evolutionary processes. Ceres, the solar system's largest asteroid at about 600 miles long, appears to have a warm surface and evidence of a weak atmosphere. Vesta is about 320 miles long and appears to have been resurfaced by basaltic lava. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] looks Like Slag
Dear list, I want to thank all of you that responded to my earlier post. It seems like my find is some type of slag. I have no idea how a piece of slag ended up where I found it, but it did. I thought it "too good to be true". Maybe those of you who have the images can submitt them to a site and list them as meteor wrongs.

Re: [meteorite-list] Tucson Auction & the U of A SWMC talks
Hi all, Some people have contacted me asking me about NOT attending the talks. So, let me clarify for everyone the flexibility offered: The talks will be given OFF TO THE END OF THE HALL, or in the major recessed area, not in the main part of the room. The main part of the room will, as always, have the tables displaying the meteorites at auction. The 4 talks are each fifteen minute talks on 4 different topics regarding meteorites. (actually, 10 to 12 minutes, with time for questions after each). (Sponsored by: Southwest Meteorite Center, University of Arizona Department of Planetary Sciences Lunar and Planetary Laboratory) They are: 6:00 The Southwest Meteorite Center - Marvin Killgore 6:15 The Importance of Meteorites - Dante Lauretta U of A 6:30 The Classification of Meteorites - Linda Welzenbach USNM 6:45 The Nomenclature of Meteorites - Harold Connolly, Jr. AMNH The hall is large enough that those not interested in the lectures, will be undisturbed and can concentrate on the auction lots, friends food and/or drink. You are in no way expected to, obligated to or forced to attend ANY of the 4 talks, rather you can check the itinerary and choose for yourself whether to attend 1, 2, 3, all or none of them. There will be plenty of socializing, specimen inspection etc. for those not interested in the talks. This is an opportunity, not a requirement. Remember, the earlier you sign in, the earlier you check out at the conclusion of the bidding. I believe the last bidder was checked out before 10:30 last year and the room definitely sounded festive throughout the evening.

Re: [meteorite-list] Meteorite?
If it is full of holes, it is most likely some sort of slag material, still, you need a nickel test.

Hello list, I decided to go out sunday morning on my ATV and do some exploring. I was deep in the woods @ 30 miles off the nearest highway. I found a few pieces of material which I am not sure of. This material is magnetic and had a significant amount of rust corrosion on it. I first thought "METEORITE!" Upon further inspection, I found many holes. I don't think that these holes are common traits of meteorites. Maybe hematite, magnetite or iron ore?

[meteorite-list] Re: Dronino & Steve Schoner's meteorite anti-rust treatment.
(Don't know if this made it thru the other day) Hi List, Went to my local hardware store to buy Red Devil Lye, but couldn't find any so I bought some (where else!) on ebay. I will be trying it out on some smaller irons that show some rust, including at least one Dronino. I was curious about Steve Schoner's 150 lb Campo mentioned in the post from November, 2003. Was the treatment successful, and what are the details? How long etc? I have one 13 lb Campo that could use a little help after I practice an a couple 100 gram slices first. Mike Fowler Chicago Bob King's post regarding Dronino: Hello Bernd, Marcin and all, I, too have had problems with Dronino until I used Steve Schoner's NaOH method. I left my slice in solution in a jar for two weeks. Every so often I'd pick up the jar and swirl the contents around to keep the chemicals mixed and monitor the process . The solution gradually became as dark as maple syrup as rust was dissolved. Then I removed the slice, washed it in distilled water (the lye makes the pieces very slippery.) and baked it in the oven for an hour at around 200 degrees. I still keep my Dronino with dessicant but I have not seen a speck of rust since this treatment. Marcin, you asked about dissolving the lye. I fill the jar halfway with regular isopropyl alcohol (off-the-shelf drugstore variety) which contains water. Then I add about 5 tablespoons of lye (Red Devil brand here in the U.S.) and stir and stir. It takes a while for the lye to dissolve in the alcohol. While this is happening you get an interesting exothermic chemical reaction and the jar warms up. Anyway, this is the only thing that's worked for really stubborn irons. Best to all, Bob Post from Steve Schoner, November 2003 By popular request, and a huge amount of e-mails regarding it, I post it now and for as long as the internet exists at: http://www.geocities.com/american_meteorite_survey/naoh.htm You can post it anywhere, share it, distribute it widely, and do so with the intent of preserving stubborn rusting meteorites that would otherwise snap crackle and pop as they flake away on the shelves, keeping one awake at night in the never ending cycle of terrestrialization. This "anti-rusting" process will help slow that down so that we can enjoy our specimens a bit longer. Currently I am soaking a 150 lb Campo and it has been in solution for 7 months. Soon I will take it out and see where it is in the process. It is the largest meteorite I have ever done in this process. Some meteorites might not respond, but most do.
