[meteorite-list] Mars Rover Opportunity Update: November 7-11, 2014
http://mars.nasa.gov/mer/mission/status.html#opportunity OPPORTUNITY UPDATE: Several Drives Push Opportunity Over 41-Kilometer Mark! - sols 3835-3839, November 7, 2014-November 11, 2014: Opportunity is on the west rim of Endeavour Crater heading towards Marathon Valley, a putative location for abundant clay minerals about a mile (1.4 kilometers) to the south. The rover has begun to pick up the pace. Sol 3836 (Nov. 8, 2014), was the first sol of a 2-sol Touch 'n Go using the robotic arm to gather information of a target of opportunity within the arm work volume from the last drive. Opportunity collected a Microscopic Imager (MI) mosaic of the surface soil target, called Rock Creek, then placed the Alpha Particle X-ray Spectrometer (APXS) on the same for a multi-hour integration. On the next sol, the rover drove about 226 feet (69 meters) to the south, passing 25.48 miles (41 kilometers) of odometry. On Sol 3839 (Nov. 11, 2014), Opportunity continued the fast-pace push to the south with over 371 feet (113 meters) of driving. The first portion was driven blind with the final part using guarded (autonomous) motion. Both drives involved collecting pre-drive targeted imaging and post-drive panoramas. An atmospheric argon measurement with the APXS was performed on Sol 3835 (Nov. 7, 2014). The rover is in good health. As of Sol 3839 (Nov. 11, 2014), the solar array energy production was 516 watt-hours with an atmospheric opacity (Tau) of 1.474 and a solar array dust factor of 0.713. Total odometry is 25.56 miles (41.14 kilometers). __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list
[meteorite-list] Second Time Through, Mars Rover Curiosity Examines Chosen Rocks
http://www.jpl.nasa.gov/news/news.php?feature=4378 Second Time Through, Mars Rover Examines Chosen Rocks Jet Propulsion Laboratory November 18, 2014 NASA's Curiosity Mars rover has completed a reconnaissance walkabout of the first outcrop it reached at the base of the mission's destination mountain and has begun a second pass examining selected rocks in the outcrop in more detail. Exposed layers on the lower portion of Mount Sharp are expected to hold evidence about dramatic changes in the environmental evolution of Mars. That was a major reason NASA chose this area of Mars for this mission. The lowermost of these slices of time ascending the mountain includes a pale outcrop called Pahrump Hills. It bears layers of diverse textures that the mission has been studying since Curiosity acquired a drilled sample from the outcrop in September. In its first pass up this outcrop, Curiosity drove about 360 feet (110 meters), and scouted sites ranging about 30 feet (9 meters) in elevation. It evaluated potential study targets from a distance with mast-mounted cameras and a laser-firing spectrometer. We see a diversity of textures in this outcrop -- some parts finely layered and fine-grained, others more blocky with erosion-resistant ledges, said Curiosity Deputy Project Scientist Ashwin Vasavada of NASA's Jet Propulsion Laboratory, Pasadena, California. Overlaid on that structure are compositional variations. Some of those variations were detected with our spectrometer. Others show themselves as apparent differences in cementation or as mineral veins. There's a lot to study here. During a second pass up the outrcrop, the mission is using a close-up camera and spectrometer on the rover's arm to examine selected targets in more detail. The second-pass findings will feed into decisions about whether to drill into some target rocks during a third pass, to collect sample material for onboard laboratory analysis. The variations we've seen so far tell us that the environment was changing over time, both as the sediments were laid down and also after they hardened into bedrock, Vasavada said. We have selected targets that we think give us the best chance of answering questions about how the sediments were deposited -- in standing water? flowing water? sand blowing in the wind? -- and about the composition during deposition and later changes. The first target in the second pass is called Pelona, a fine-grained, finely layered rock close to the September drilling target at the base of Pahrump Hills outcrop. The second is a more erosion-resistant ledge called Pink Cliffs. Before examining Pelona, researchers used Curiosity's wheels as a tool to expose a cross section of a nearby windblown ripple of dust and sand. One motive for this experiment was to learn why some ripples that Curiosity drove into earlier this year were more difficult to cross than anticipated. While using the rover to investigate targets in Pahrump Hills, the rover team is also developing a work-around for possible loss of use of a device used for focusing the telescope on Curiosity's Chemistry and Camera (ChemCam) instrument, the laser-firing spectrometer. Diagnostic data from ChemCam suggest weakening of the instrument's smaller laser. This is a continuous wave laser used for focusing the telescope before the more powerful laser is fired. The main laser induces a spark on the target it hits; light from the spark is received though the telescope and analyzed with spectrometers to identify chemical elements in the target. If the smaller laser has become too weak to continue using, the ChemCam team plans to test an alternative method: firing a few shots from the main laser while focusing the telescope, before performing the analysis. This would take advantage of more than 2,000 autofocus sequences ChemCam has completed on Mars, providing calibration points for the new procedure. Curiosity landed on Mars in August 2012, but before beginning the drive toward Mount Sharp, the rover spent much of the mission's first year productively studying an area much closer to the landing site, but in the opposite direction. The mission accomplished its science goals in that Yellowknife Bay area. Analysis of drilled rocks there disclosed an ancient lakebed environment that, more than three billion years ago, offered ingredients and a chemical energy gradient favorable for microbes, if any existed there. Curiosity spent its second year driving more than 5 miles (8 kilometers) from Yellowknife Bay to the base of Mount Sharp, with pauses at a few science waypoints. NASA's Mars Science Laboratory Project is using Curiosity to assess ancient habitable environments and major changes in Martian environmental conditions. JPL, a division of the California Institute of Technology in Pasadena, built the rover and manages the project for NASA's Science Mission Directorate in Washington. For more information
[meteorite-list] Did Philae Drill The Comet?
http://blogs.esa.int/rosetta/2014/11/19/did-philae-drill-the-comet/ Did Philae drill the comet? European Space Agency November 19, 2014 Philae's Sampling, Drilling and Distribution (SD2) subsystem was activated towards the end of the surface operations that Philae performed on Comet 67P/Churyumov-Gerasimenko last week, despite fears that it might alter the lander's precarious position following its third touchdown. Here we present the latest update from the SD2 team. SD2's goal was to drill into the comet surface in order to collect and deliver samples to the COSAC and Ptolemy instruments inside the lander (Click here for our introductory post on SD2). It was the last of the lander's ten instruments to be operated. @Philae2014 tweeted that the drill was activated as planned SD2 principal investigator Amalia Finzi has reported that the drill was deployed as planned, extending 46.9 cm below the balcony of the lander and 56.0 cm from its reference point. It was then retracted to the reference position, the carousel turned in a way that the sampling tube was in front of the right oven, the discharge operation from the sampling tube to the oven was completed, and the carousel rotated in a way that that oven was positioned at COSAC's location, she said. Although the ovens worked correctly, the scientists do not yet know how much - if any - material was actually delivered to the ovens by SD2, or whether the instruments sampled dust or gas that entered the chamber during the touchdown. Because Philae was not anchored to the comet surface, it is also possible that, if the drill touched a particularly hard surface material, it moved the lander instead of drilling into the surface. Furthermore, the SD2 instrument lacks dedicated sensors to determine whether or not the surface has been reached, whether a sample was then collected in the sample tube, or if it was then discharged into the oven. But other instruments on board Philae can help understand what actually happened. For example, the downward-looking ROLIS camera obtained two images of the surface under the balcony, one before and one after the lander's main body was lifted and rotated. Because of those movements, the SD2 footprint' may be included in those images and thus may be able to provide visual evidence that the drill interacted with the surface. We hope to be able to provide an update on this soon. As for whether COSAC received a sample from the drill, the analysis is on-going. As far as we can see at the moment, SD2 and COSAC telemetry cannot reliably discern between lack of sample and insufficient gas generation from it, says Amalia. A CIVA-MV/MI image would have been needed for this purpose, which was not available for the first sample. Meanwhile, COSAC's analyses on the data acquired from its surface measurements are on-going. But it is apparent that COSAC already sniffed' the comet's atmosphere during the first touchdown, detecting organic molecules. The Ptolemy instrument is also reported to have successfully collected the ambient gases of the comet. Analysis of the spectra and identification of the molecules detected by both instruments are continuing. Mario Salatti, Philae Program Manager for ASI adds: We are all hoping that Philae wakes up and we can perform many more measurements on the surface of the comet, including the chance to drill again with SD2. The final site where Philae landed does not enjoy long exposure to sunlight, but on the other hand, it opens new perspectives. As the lander appears to be currently shielded by walls, the local temperature may be lower than it would have been at the chosen landing site. So if Philae wakes up, it might remain operative much longer than expected, possibly until perihelion, which is extremely exciting. The SD2 (Sample Drilling Distribution) instrument was conceived by technologists at the Italian Space Agency, designed and developed by the SELEX ES in Milan, under the scientific responsibility of the Principal Investigator Prof. Amalia Ercoli Finzi from Politecnico di Milano: for more than 10 years, SD2 team has been planning SD2 operation sequences and validated them with the unit spare available at their institution's laboratories.

[meteorite-list] Pasadena To Host COSPAR Planetary Conference in 2018
http://www.pasadenastarnews.com/science/20141118/pasadena-to-host-cospar-planetary-conference Pasadena to host COSPAR planetary conference Pasadena Star News November 18, 2014 PASADENA - One of the most prestigious scientific meetings in the world will be hosted in Pasadena in 2018 - only the fifth time the Committee on Space Research has come to the United States in the past 56 years. At the biannual COSPAR assemblies, organized to promote international collaboration, scientists present their avant-garde space discoveries. Previous gatherings have played a central role in formulating such disciplines as Earth and planetary science. The California Institute of Technology will host the event - Pasadena's largest ever scientific conference - with the aid of the Jet Propulsion Laboratory, said Caltech president Thomas Rosenbaum. I know that you are well aware of the pivotal roles played by Caltech and JPL in space science since the very dawn of the Space Age almost six decades ago, Rosenbaum wrote in a letter to the president of COSPAR when campaigning for the conference. Pasadena won the 2018 bid against contenders Denver and Kuala Lumpur, Malaysia. The first U.S. space probe and the first actual space science mission, Explorer 1, was designed and built by JPL in 1958, the same year as the creation of COSPAR. It seems particularly fitting, then, that we should host COSPAR in Pasadena, California, on the 60th anniversary of the founding of COSPAR and the 60th anniversary of Explorer 1. Mayor Bill Bogaard, the Pasadena Center Operating Company, Caltech and JPL hosted a press conference Tuesday to announce everyone's excitement in winning the competitive bid for the 42nd COSPAR Scientific Assembly, set to take place July 14-22, 2018. The most recent conference took place this summer in Moscow, and the last time it was in America was in Houston in 2002. An estimated 3,500 to 4,000 scientists are expected, said Michael Ross, chief executive officer of the Pasadena Center Operating Company. Bogaard noted Pasadena is perfectly suited for these kinds of conferences. As the home of the world-renowned California Institute of Technology and the world-renowned Jet Propulsion Laboratory, we're prepared and poised to welcome this very distinguished international group to Pasadena, he said. These elite institutions are at the forefront of space, technology, engineering, mathematics and advanced-edge science. We are deeply proud of the remarkable roles that they have played on behalf of humanity in the scientific exploration of space. JPL has led 52 of NASA's 71 planetary missions, and Caltech is home to 32 Nobel Prize winners as well as 57 National Medal of Science recipients. While the conference won't cost Caltech or JPL anything, said Gregg Vane, spokesman for JPL, the institutions have so much to gain. Our community of scientists will have an opportunity to interact with 3,500 scientists from around the world without having to leave home, he said. They will invite them to their laboratories. They will initiate new partnership ideas. ... So this will give opportunities for the scientists here in the Pasadena area to form partnerships they might not be able to do otherwise. According to Ross, the event is expected to fill 6,500 hotel room nights and bring millions of dollars to the city. We know people will come early and stay late because they're coming internationally, he said. Tourist dollars will benefit the city's hotels, restaurants, bars, nightclubs, museums and retail stores, Ross said. His team has yet to predict COSPAR's economic impact on the San Gabriel Valley. Previous COSPARs have been hosted by Warsaw, Beijing, Paris, Tel-Aviv and Prague. As Astronomer Royal Martin Rees famously said, The universe of astronomy has no center, but the universe of astronomers does. For years, that center has been Pasadena. __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list
[meteorite-list] Ad, Sale. newly classified Howardite
Greetings all, I'd like to announce NWA 8615, a new Howardite that I purchased earlier this year and was just recently classified. Carl Agee describes it as Two matching stones, weathered exterior with some caliche. A saw-cut reveals a breccia of light and dark clasts set in dark brown matrix. Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows a highly brecciated texture with ~50% diogenitic pyroxenes, ~25% gabbroic eucrite pyroxenes showing Fe zoning, and ~25% equilibrated basaltic eucrite clasts showing clear separation between augite and pigeonite, with coarse exsolution lamellae. Accessory Fe-Ni metal, troilite, Ti-rich chromite, chromite, and ilmenite throughout. Geochemistry: (C. Agee and N. Muttik, UNM) Diogenite orthopyroxene Fs28.8±6.2Wo2.4±1.4, Fe/Mn=34±6, n=10; gabbroic eucrite low-Ca pyroxene Fs47.1±3.7Wo4.7±3.7, Fe/Mn=36±6, n=8, basaltic eucrite augite Fs44.3±11.0Wo27.0±12.6, Fe/Mn=34±1, n=3; basaltic eucrite pigeonite Fs62.9±1.2Wo6.6±1.9, Fe/Mn=33±2, n=3; plagioclase An89.3±2.5Ab10.2±2.3Or0.5±0.2, n=6. Classification: Achondrite (howardite) with three lithologies: 1) diogenite, 2) unequilibrated gabbroic eucrite with zoned pyroxenes, 3) equilibrated basaltic eucrite. TKW is only 109 grams, so after type specimen and cut loss, there is only a small amount of this material available. I've listed 10 pieces tonight and will list a dozen or so more tomorrow. Free shipping on orders over $100. I have put photos on Flickr. In the past I have marked sold specimens in the description. This has created some confusion. From now on, as items sell, I will remove the picture of the sold specimens. Price is $20 per gram for a limited time. See: https://www.flickr.com/photos/stevewitt/sets/72157648967596398/ Please also check out my other albums with specimens for sale here: https://www.flickr.com/photos/stevewitt/sets thanks for your time, Steve Steve Witt IMCA #9020 http://imca.cc/ __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list
[meteorite-list] Video of meteor smoke ring
List, One of our local radio stations posted this link to a short video captured by an amateur astronomer that, if real (??), seems to show a meteor producing a pretty cool smoke ring upon disintegration and/or the train being twisted around by high altitude winds. The train it produced appears to have lasted for several minutes in this sped up video. I have had trouble in the past with my email provider in getting links to go thru to the list if I type it intact, so you will need to enter it as below, but obviously without any spaces at all between any of the parts. If you haven't seen this before, and if this is real event and not just computer generated, it is pretty cool, and only 10 secs long.

Re: [meteorite-list] MASSSIVE Russian Event Asteroid? 14NOV2014
Marcin, List The Sverdlovsk region is quite isolated and dense with weapon development centers of all kinds. In 1979, a germ warfare agent, aerosolized anthrax spores, escaped from a laboratory where they were being manufactured in weaponized form and killed an uncertain number of people (~100?). http://www.pbs.org/wgbh/pages/frontline/shows/plague/sverdlovsk/ and http://www.cbsnews.com/news/ussr-anthrax-outbreak-still-a-mystery/ A local news site suggests there's an old chemical plant outside the nearby town of Rezh, the explosion of which would be consistent with this phenomenon, and one local on the forum of Astronomy.ru wrote there were also reports of the military setting off ammunition. http://www.nbcnews.com/science/weird-science/meteor-ufo-flash-over-russia-ma y-have-earthly-origin-n251081 Maybe they had to sterilize something? In any case, it's very unlikely this was a natural celestial event, I'm afraid.

Also there seems to be fog or dense clouds so the whole flash will be false. But yes, this could be just big explosion in factory. -[ MARCIN CIMALA ]-[ I.M.C.A.#3667 ]- http://www.Meteoryty.pl marcin(at)meteoryty.pl http://www.PolandMET.com marcin(at)polandmet.com http://www.Gao-Guenie.com GSM: +48 (793) 567667 [ Member of Polish Meteoritical Society ] I think some kind of explosion, aircraft or chemical plant. Meteor would be faster and move. This was something else I think.
