Re: [meteorite-list] Experiment Update #1
Göran & all, I don't understand the chemistry involved, but I have personally used a concentrated sodium hydroxide bath to remove rust from very rusty Campos. It took weeks, but scales of rust just kept detaching untill the bottom of the pail was a centimeter deep in rust flakes. I did do a final treatment with a wire brush, but ended with a beautiful metallic specimen. This treatment wasn't just a rust stopper. It removed rust in large quantities. The solution didn't discolor as if iron was being dissolved. Flakes just popped off and fell to the bottom.

Re: [meteorite-list] Experiment Update #1
Hi, Liquid Drano contains sodium hypochlorite as well as sodium hydroxide, so there are plenty of chlorine ions in this solution, and soaking in it is likely to increase the chlorine ions in the iron rather than leach them out.

[meteorite-list] Lunar Meteorite on Display at Belfast Museum
http://news.bbc.co.uk/2/hi/uk_news/northern_ireland/4765656.stm Rare moon rock on show at museum BBC News March 2, 2006 A Belfast museum is quite literally over the moon about its latest acquisition. A rare piece of moon rock, which was found in Oman in 2001, is being unveiled this weekend. It is part of the Ulster museum's Rocky Roadshow, which explores all sorts of rocks and fossils. A museum spokeswoman said: "All of the moon rock on earth would fit into the boot of a small car - making our small piece of rock far more valuable and rare than gold or diamonds." More than 90% of the lunar rocks on earth were brought back by the Apollo astronauts and are owned by Nasa. But the rock going on show fell to earth as a meteorite after being blasted off the moon's surface by the impact of another meteorite. The spokeswoman added: "Although it weighs only 6.39 grams, this is one of the largest pieces of moon rock on display outside of the USA. "What is even more amazing is that it probably came from the far side of the moon. This was an area never visited by the Apollo astronauts and never seen from earth." About 20,000 space rocks are estimated to land on this planet every year but very few hail from the moon. One of the few ways to understand the chemistry of the moon's surface is by analysing these lunar meteorites - little fragments of rock that are flung into space during great impacts before occasionally winding up on earth. Only about 30 of them have ever been found in deserts around the globe. Lunar meteorites are useful for building up a data base of the range of rocks on the moon. But it is hard to work out which rocks come from where, because moon rocks can betray their place of origin. If you wish, you can bring your own rocks to the Rocky Roadshow and the museum's experts will do their best to tell you more. The Rocky Roadshow is on from 1330 - 1630 GMT on Saturday and from 1430 - 1630 GMT on Sunday.

[meteorite-list] Instruments of Cosmochemistry: Ion Microprobe
http://www.psrd.hawaii.edu/Feb06/PSRD-ion_microprobe.html Instruments of Cosmochemistry Ion Microprobe Planetary Science Research Discoveries February 28, 2006 Written by Linda M. V. Martel and G. Jeffrey Taylor Hawai'i Institute of Geophysics and Planetology In this series of articles, "Instruments of Cosmochemistry," PSRD highlights the essential tools and amazing technology used by talented scientists seeking to unravel how the solar system formed. You will find information on how the instruments work as well as how they are helping new discoveries come to light.lightbulb Precision Instrument The ion microprobe is a Secondary Ion Mass Spectrometer (SIMS), a precision instrument used to quantitatively analyze the elements and isotopes of materials at microscopic scales. This complicated instrument consists of an ion source, mass spectrometer, detection system, associated electronics, and vacuum system. A schematic diagram of an ion microprobe is presented later, but first we'll look at the instrument's use of a primary ion beam to bombard a sample of material and how that gives us information about the material's composition. In SIMS analysis, a primary, high-energy beam of ions (usually oxygen, argon, or cesium) is aimed at a small area of a sample, such as a mineral grain. The primary ions have energies on the order of 10,000 electron volts. (An electron volt is the energy given to an electron by accelerating it through 1 volt of electric potential difference. The electrons in a typical television screen ... not the new flat-screens... have about 20,000 electron volts.) The primary ions dig a hole into the sample causing sputtering of atoms and ions (called secondary ions) that reveal the elemental and isotopic characteristics of the sample. See graphic below. [graphic of supttering] Artist's rendition of an incoming beam of ions (colored purple) impacting a sample and sputtering off the upper few layers of particles (colored red, green, and blue) some of which are ions. These secondary ions (approximately 1% of the sputtered material) are accelerated into a mass spectrometer, where they are sorted by mass/charge ratios with a large sector magnet. See diagram below. [ions through mass spec] [light through prism] TOP: In a mass spectrometer, ions travel different paths through the magnet to the detector due to their mass/charge ratios. A mass analyzer sorts the ions according to mass/charge ratios and the detector records the abundance of each ratio. BOTTOM: For an analogy, think of how a prism refracts and scatters white light separating it into a spectrum of rainbow colors. A series of ion detectors counts the ions in different mass categories. Analysts take these raw counts, apply corrections, and normalize them to well-analyzed standards to arrive at the true abundances of elements and isotopes in the original sample. (Read an account of SIMS in use in PSRD article: A New Type of Stardust) The diagram, below, shows the entire instrument scheme. [schematic diagram of an ion microprobe] The different components of an ion microprobe are numbered and color-coded in this diagram. Ion beam paths are shown in white. Starting from the left, the primary ion column (yellow) provides the highly-focused ion beam produced from one of two sources (1,2). The sample (5, red) is located where the primary ion column joins the secondary ion extraction system (blue) wherein lenses focus the sputtered secondary ions into the mass spectrometer entrance slit (9, orange). The secondary-ion mass spectrometer (orange) is a double focusing mass spectrometer with both electrostatic and magnetic sectors. The electrostatic analyzer (10) bends lower energy ions more strongly than higher energy ions. The ions then pass through the electromagnet sector (13) where lower mass ions are bent more than higher mass ions. Finally, the secondary ions pass to the sensitive detection systems (green), which include an electron multiplier for counting individual ions (19), and Faraday cup for measuring ion current (20). CamecaTM ims-series ion microprobes also have the capability to operate in "ion microscope" mode, providing elemental and isotopic imaging capability at ~1 micrometer spatial resolution. The images are captured by an imaging device consisting of a channel-plate (17) and a fluorescent screen (18) in the detection system. SIMS analysts may choose to vary several features of the instrument: (1) the polarity and species of the primary ion beam (O-, O2+, Ar+, Cs+ are often used), (2) the impact energy (between ~3,000-20,000 electron volts), current, and diameter of the primary ion beam, (3) the polarity of the secondary ion beam, and (4) the initial kinetic energies of the secondary ions detected.

[meteorite-list] Two Other Mars Missions Heating Up
http://news-info.wustl.edu/news/page/normal/6575.html Two other Mars missions heating up Radar mapping polar caps, impact craters By Tony Fitzpatrick Washington University in St. Louis March 1, 2006 Two Mars orbiter missions - one from NASA, the other from the European Space Agency (ESA) - will open new vistas in the exploration of Mars through the use of sophisticated ground-penetrating radars, providing international researchers with the first direct clues about the Red Planet's subsurface structure. Roger Phillips, Ph.D., Washington University in St. Louis Professor of Earth and Planetary Sciences in Arts & Sciences, is participating in both the Mars Express (ESA) and NASA's Mars Reconnaissance Orbiter (MRO) missions by lending his expertise in radar. Phillips says that the combination of the radars on the two missions will provide important and unique data sets that will directly map the structure of the upper portions of the interior of Mars. The Mars Reconnaissance Orbiter (above) is poised to go into orbit around Mars in March, then spend about six months aerobraking to place the spacecraft in a low circular orbit by this fall. Roger Phillips, Ph.D., WUSTL professor of earth and planetary sciences and director of the university's McDonnell Center for the Space Sciences, is lending his expertise in radar for both the MRO and for the European Space Agency's Mars Express. Mars Express features an instrument called the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS); Mars Reconnaissance Orbiter's radar instrument is called the Shallow Subsurface Radar (SHARAD). Both instruments have been built primarily by the Italian Space Agency, and, says Phillips, they are complementary. Mars Express went into orbit on Christmas Day of 2003, but the radar developed some technical problems and didn't start operating until the summer of 2005. One of the problems was making sure that the craft's long antennas would unfold without damaging the spacecraft. This necessitated a full stop, followed by many hardware and computer simulations until confidence was gained that the antennas could be deployed safely. The first data were published in the journal Science late last year, with Phillips a co-author along with approximately 30 European and American colleagues. "One of the spectacular results of that paper is the fact that we've sounded the northern polar cap of Mars, the radar signals penetrating all the way to the bottom of the icy cap and bouncing back so that we can see right down to the cap's base, nearly two kilometers deep," Phillips says. "This result tells us that we will eventually be able to map the volume of both the northern and southern ice caps, which will provide a much better understanding of the origins and evolution of these features and the amount of water that is tied up frozen in the caps. The radar is looking inside the planet directly - that's never been done before on Mars." The northern cap data also provide the Mars Express team with the first direct observation of how the load of the ice cap deforms the planet's underlying crust - a phenomenon called flexure. There is in fact no flexure observed within the error limits of the radar data, which means that the crust beneath the northern polar cap is very strong, says Phillips. "That also tells us that the heat output of the planet at present is quite low. There have been theoretical models predicting this, but never a direct observation until now. " Finding unfrozen subsurface water is a possibility, too; this is the Holy Grail of MARSIS, Phillips says. "At the boundary of a water-rich environment we should see a very strong reflection. Whether we find such a reflector remains to be seen - we're in the early days of gathering data. Right now MARSIS is carrying out a campaign to map the structure of the southern polar cap." Phillips says that the MARSIS radar also has mapped buried impact craters, which should revise the theory of how old the martian crust is and how it evolved. SHARAD will likely not probe as deeply as MARSIS, but it has ten times the vertical resolution, allowing for opportunities to map detailed subsurface stratigraphy, says Phillips, who is also director of Washington University's McDonnell Center for the Space Sciences The MRO spacecraft is now poised to go into orbit around Mars in March, and will then spend about six months aerobraking to place the spacecraft in a low circular orbit by this fall. This will mark the start of a two-year mapping campaign that NASA calls the primary science phase. Phillips is Deputy Team Leader for the MRO SHARAD experiment. The Team Leader is Roberto Seu, Ph.D., of the INFOCOM Department at the University of Rome, La Sapienza, Italy. "I think that SHARAD will be an excellent mapper of the sedimentary layers on Mars, and that will help us better understand the water history of the planet, "Phillips says. "One of my hopes is to connect what SHARAD maps in
