[meteorite-list] Rover Opportunity Wrapping up Study of Martian Valley
http://www.jpl.nasa.gov/news/news.php?feature=6536 Rover Opportunity Wrapping up Study of Martian Valley Jet Propulsion Laboratory June 14, 2016 "Marathon Valley," slicing through a large crater's rim on Mars, has provided fruitful research targets for NASA's Opportunity rover since July 2015, but the rover may soon move on. Opportunity recently collected a sweeping panorama from near the western end of this east-west valley. The vista shows an area where the mission investigated evidence about how water altered the ancient rocks and, beyond that, the wide floor of Endeavour Crater and the crater's eastern rim about 14 miles (22 kilometers) away. Marathon Valley lured the mission because researchers using NASA's Mars Reconnaissance Orbiter had mapped water-related clay minerals at this area of the western rim of Endeavour Crater. The rover team chose the valley's informal name because Opportunity's arrival at this part of the rim coincided closely with the rover surpassing marathon-footrace distance in total driving since its January 2004 Mars landing. "We are wrapping up our last few activities in Marathon Valley and before long we'll drive away, exiting along the southern wall of the valley and heading southeast," said Opportunity Principal Investigator Steve Squyres, of Cornell University, Ithaca, New York. As Opportunity examined the clay-bearing rocks on the valley floor that were detected from orbit, the rover's own observations of the valley's southern flank revealed streaks of red-toned, crumbly material. The science team chose to investigate this apparently weathered material. The rover approached exposures of it to prepare for using the Rock Abrasion Tool, called the RAT. This tool grinds away a rock's surface to expose the interior for inspection. "What we usually do to investigate material that's captured our interest is find a bedrock exposure of it and use the RAT," Squyres said. "What we didn't realize until we took a close-enough look is that this stuff has been so pervasively altered, it's not bedrock. There's no solid bedrock you could grind with the RAT." Instead, the rover exposed some fresh surfaces for inspection by scuffing some of the reddish material with a wheel. Squyres said, "In the scuff, we found one of the highest sulfur contents that's been seen anywhere on Mars. There's strong evidence that, among other things, these altered zones have a lot of magnesium sulfate. We don't think these altered zones are where the clay is, but magnesium sulfate is something you would expect to find precipitating from water. "Fractures running through the bedrock, forming conduits through which water could flow and transport soluble materials, could alter the rock and create the pattern of red zones that we see." As of June 14, Opportunity has driven 26.59 miles (42.79 kilometers). NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, built the rover and manages the mission for NASA's Science Mission Directorate, Washington.

[meteorite-list] NASA Mars Curiosity Rover Descends Plateau, Turns Toward Mountain
http://www.jpl.nasa.gov/news/news.php?feature=6532 NASA Mars Rover Descends Plateau, Turns Toward Mountain Jet Propulsion Laboratory June 13, 2016 NASA's Curiosity Mars rover has analyzed its 12th drilled sample of Mars. This sample came from mudstone bedrock, which the rover resumed climbing in late May after six months studying other features. Since the previous time Curiosity drilled into this "Murray formation" layer of lower Mount Sharp, the mission has examined active sand dunes along the rover's route, then crossed a remnant plateau of fractured sandstone that once more extensively covered the Murray formation. While on the "Naukluft Plateau," the rover examined its 10th and 11th drill targets to repeat an experiment comparing material within and away from pale zones around fractures. From there, Curiosity also took the latest in a series of self-portraits. "Now that we've skirted our way around the dunes and crossed the plateau, we've turned south to climb the mountain head-on," said Curiosity Project Scientist Ashwin Vasavada, of NASA's Jet Propulsion Laboratory, Pasadena, California. "Since landing, we've been aiming for this gap in the terrain and this left turn. It's a great moment for the mission." Curiosity landed near Mount Sharp in 2012. It reached the base of the mountain in 2014 after successfully finding evidence on the surrounding plains that ancient Martian lakes offered conditions that would have been favorable for microbes if Mars has ever hosted life. Rock layers forming the base of Mount Sharp accumulated as sediment within ancient lakes billions of years ago. The Murray formation is about one-eighth of a mile (200 meters) thick. So far, Curiosity has examined about one-fifth of its vertical extent. "The story that the Murray formation is revealing about the habitability of ancient Mars is one of the mission's surprises," Vasavada said. "It wasn't obvious from pre-mission data that it formed in long-lived lakes and that its diverse composition would tell us about the chemistry of those lakes and later groundwater." The latest sample-collection target, "Oudam," was drilled on June 4. On the Naukluft Plateau, Curiosity drilled "Lubango," within a halo of brighter sandstone near a fracture, and "Okoruso," away from a fracture-related halo, for comparison. The mission conducted a similar experiment last year, with two sample targets drilled at another exposure of the fractured sandstone. This sandstone unit, called the Stimson formation, is interpreted to have resulted from wind that draped a band of sand dunes over lower Mount Sharp. That would have been after the main stack of the mountain's lower layers had formed and partially eroded. Water later moved through fractures in the sandstone. Investigation of the fracture-related halos aims to determine how fluid moved through the fractures and altered surrounding rock. "We were about to drive off the Naukluft Plateau and leave the Stimson formation forever as we go up Mount Sharp," said Curiosity science-team member Albert Yen of JPL. "A few of us were concerned. The fracture-associated haloes were becoming more prevalent, and we had only one data point. With just one data point, you never know whether it is representative." As with the similar previous experiment, comparison of Lubango and Okoruso found higher silica and sulfate levels in the sample nearer to the fracture. Multiple episodes of groundwater flow with different chemistry at different times may have both delivered silica and sulfate from elsewhere and leached other ingredients away. "The big-picture story is that this may be one of the youngest fluid events we're likely to study with Curiosity," Yen said. "You had to lay down the Murray, then cement it, then lay down the Stimson and cement that, then fracture the Stimson, then have fluids moving through the fractures." On Mount Sharp, Curiosity is investigating how and when the habitable ancient conditions known from the mission's earlier findings evolved into conditions drier and less favorable for life.

[meteorite-list] NASA Mars Orbiters Reveal Seasonal Dust Storm Pattern
http://www.jpl.nasa.gov/news/news.php?feature=6529 NASA Mars Orbiters Reveal Seasonal Dust Storm Pattern Jet Propulsion Laboratory June 9, 2016 Fast Facts: * A pattern of three large regional dust storms occurs with similar timing most Martian years. * The seasonal pattern was detected from dust storms' effects on atmospheric temperatures, monitored by NASA orbiters since 1997. * Improving the ability to predict large-scale, potentially hazardous dust storms on Mars would have safety benefits for planning robotic and human missions. After decades of research to discern seasonal patterns in Martian dust storms from images showing the dust, but the clearest pattern appears to be captured by measuring the temperature of the Red Planet's atmosphere. For six recent Martian years, temperature records from NASA Mars orbiters reveal a pattern of three types of large regional dust storms occurring in sequence at about the same times each year during the southern hemisphere spring and summer. Each Martian year lasts about two Earth years. "When we look at the temperature structure instead of the visible dust, we finally see some regularity in the large dust storms," said David Kass of NASA's Jet Propulsion Laboratory, Pasadena, California. He is the instrument scientist for the Mars Climate Sounder on NASA's Mars Reconnaissance Orbiter and lead author of a report about these findings posted this week by the journal Geophysical Research Letters. "Recognizing a pattern in the occurrence of regional dust storms is a step toward understanding the fundamental atmospheric properties controlling them," he said. "We still have much to learn, but this gives us a valuable opening." Dust lofted by Martian winds links directly to atmospheric temperature: The dust absorbs sunlight, so the sun heats dusty air more than clear air. In some cases, this can be dramatic, with a difference of more than 63 Fahrenheit degrees (35 Celsius degrees) between dusty air and clear air. This heating also affects the global wind distribution, which can produce downward motion that warms the air outside the dust-heated regions. Thus, temperature observations capture both direct and indirect effects of the dust storms on the atmosphere. Improving the ability to predict large-scale, potentially hazardous dust storms on Mars would have safety benefits for planning robotic and human missions to the planet's surface. Also, by recognizing patterns and categories of dust storms, researchers make progress toward understanding how seasonal local events affect global weather in a typical Mars year. NASA has been operating orbiters at Mars continuously since 1997. The Mars Climate Sounder on Mars Reconnaissance Orbiter, which reached Mars in 2006, and the Thermal Emission Spectrometer on Mars Global Surveyor, which studied Mars from 1997 to 2006, have used infrared observations to assess atmospheric temperature. Kass and co-authors analyzed temperature data representative of a broad layer centered about 16 miles (25 kilometers) above the Martian surface. That's high enough to be more affected by regional storms than by local storms. Most Martian dust storms are localized, smaller than about 1,200 miles (about 2,000 kilometers) across and dissipating within a few days. Some become regional, affecting up to a third of the planet and persisting up to three weeks. A few encircle Mars, covering the southern hemisphere but not the whole planet. Twice since 1997, global dust storms have fully enshrouded Mars. The behavior of large regional dust storms in Martian years that include global dust storms is currently unclear, and years with a global storm were not included in the new analysis. Three large regional storms, dubbed types A, B and C, all appeared in each of the six Martian years investigated. Multiple small storms form sequentially near Mars' north pole in the northern autumn, similar to Earth's cold-season arctic storms that swing one after another across North America. "On Mars, some of these break off and head farther south along favored tracks," Kass said. "If they cross into the southern hemisphere, where it is mid-spring, they get warmer and can explode into the much larger Type A dust storms." Southern hemisphere spring and summer on modern-day Mars are much warmer than northern spring and summer, because the eccentricity of Mars' orbit puts the planet closest to the sun near the end of southern spring. Southern spring and summer have long been recognized as the dustiest part of the Martian year and the season of global dust storms, even though the more detailed pattern documented in the new report had not been previously described. When a Type A storm from the north moves into southern-hemisphere spring, the sunlight on the dust warms the atmosphere. That energy boosts the speed of winds. The stronger winds lift more dust, further expanding the area and vertical reach of

[meteorite-list] Mars Rover Opportinty Update: May 17 - June 14, 2016
OPPORTUNITY UPDATE: sols 4378-4384, May 17, 2016-May 24, 2016: Investigating the Soil Exposed with the Rover Wheel Opportunity is exploring 'Marathon Valley' on the rim of Endeavour crater, inspecting specific outcrops for evidence of clay minerals. Previously, the rover used the left-front wheel to scuff a red vein feature to break up and expose its compositional material for further investigation. On Sol 4379 (May 18, 2016), Opportunity bumped 6 feet (1.75 meters) back towards the scuff to set up for an in-situ (contact) investigation of the scuffed material. The rover also collected some targeted Panoramic Camera (Pancam) 13-filter images and a Navigation Camera (Navcam) panorama. On Sol 4381 (May 21, 2016), Opportunity began the contact investigation using the robotic arm to collect a Microscopic Imager (MI) mosaic of the scuff and then place the Alpha Particle X-ray Spectrometer (APXS) on the same. On the next sol, the rover offset the APXS on the scuff by about 1 centimeter and performed another integration. Opportunity continued on the next sol with yet another APXS offset placement, more MI mosaics and some more targeted Pancam 13-filter imaging. As of Sol 4384 (May 24, 2016), the solar array energy production is 636 watt-hours with an atmospheric opacity (Tau) of 0.605 and a solar array dust factor of 0.756. Total odometry is 26.59 miles (42.79 kilometers), more than a marathon. -- sols 4385-4391, May 25, 2016-May 31, 2016: Study of 'Wheel Scuff' Continues Opportunity is exploring 'Marathon Valley' on the rim of Endeavour crater, investigating outcrops for evidence of clay minerals. The rover is continuing to examine a previously trenched (scuffed) surface. On Sol 4385 (May 25, 2016), Opportunity collected some more targeted Panoramic Camera (Pancam) 13-filter images and continued with an Alpha Particle X-ray Spectrometer (APXS) integration on the surface target. Then, on Sol 4386 (May 26, 2016), Opportunity bumped ever so slightly (about 1 cm) in order to reach a particular yellow pebble in the trenched area. The rover collected more targeted 13-filter Pancam images. And then on Sol 4389 (May 29, 2016), Opportunity used the robotic arm (IDD) to collect a Microscopic Imager (MI) mosaic of the yellow pebble and to position the APXS just above the pebble (since it was too small to make a contact placement). More targeted color Pancam images have been collected over the subsequent sols. As of Sol 4391 (May 31, 2016), the solar array energy production is 643 watt-hours with an atmospheric opacity (Tau) of 0.566 and a solar array dust factor of 0.738. Total odometry is 26.59 miles (42.79 kilometers), more than a marathon. -- ls 4392-4398, June 01, 2016-June 07, 2016: Examining Pebbles Exposed by 'Wheel Scuff' Opportunity is exploring 'Marathon Valley' on the rim of Endeavour crater, investigating outcrops for evidence of clay minerals. The rover is continuing to examine a previously trenched (scuffed) surface where distinct pebbles have become a focus of interest for the science team. On Sol 4392 (June 1, 2016), Opportunity continued the investigation of a 'yellow' pebble with an offset positioning of the Alpha Particle X-ray Spectrometer (APXS). This pebble has exhibited an elevated sulfate composition. Offset APXS measurements allow the 'teasing out' of the elements associated with the pebble versus those in the background (soil). Over the next two sols, the APXS was allowed to integrate while the rover collected several multi-color panoramic images of the surroundings. On Sol 4395 (June 4, 2016), the rover performed another offset positioning of the APXS followed with a multi-hour integration. On the next sol, a Microscopic Imager (MI) mosaic was collected using the robotic arm and the APXS was offset again for yet another integration. On Sol 4398 (June 7, 2016), with the work complete on the 'yellow' pebble, the rover bumped about 4 inches (10 centimeters) to another pebble of interest for in-situ (contact) investigation over the coming sols. As of Sol 4398 (June 7, 2016), the solar array energy production is 637 watt-hours with an atmospheric opacity (Tau) of 0.597 and a solar array dust factor of 0.735. Total odometry is 26.59 miles (42.79 kilometers), more than a marathon. -- sols 4399-4405, June 08, 2016-June 14, 2016: Opportunity Wraps up Work on 'Wheel Scuff' Opportunity is exploring 'Marathon Valley' on the rim of Endeavour crater, investigating outcrops for evidence of clay minerals. The rover is close to completing its investigations within Marathon Valley. On Sol 4400 (June 9, 2016), Opportunity continued with the in-situ (contact) investigation of the area that was scuffed by the rover wheel. The rover collected a Microscopic Imager (MI) mosaic of the 'red pebble' target and then placed the Alpha Particle X-ray Spectrometer (APXS) on the same for a multi-hour integration. On Sols 4402 and
[meteorite-list] Dawn Journal - May 31, 2016
http://dawn.jpl.nasa.gov/mission/journal_05_31_16.html Dawn journal Dr. Marc Rayman May 31, 2016 Dear Phodawngraphers, Dawn is continuing to record the extraordinary sights on dwarf planet Ceres. The experienced explorer is closer to the alien world than the International Space Station is to Earth. Dawn has completed more than 1,000 orbital revolutions since entering into Ceres' gentle but firm gravitational grip in March 2015. The probe is healthy and performing its ambitious assignments impeccably. In the last few months, we have described how Dawn has greatly exceeded all of its original objectives at Ceres and the excellent progress it has been making in collecting bonus data. On schedule on May 25, the spacecraft completed the mapping campaign it began on April 11, in which it took photographs with the camera pointed to the left and forward as it circled Ceres. Now it is looking to the right and forward to get another stereo view. In January we mentioned that, having already acquired far more measurements with the visible and infrared mapping spectrometer than anticipated, scientists were devoting further observations to infrared rather than visible. Now Dawn is operating both spectrometers again. Having seen much more of Ceres in the infrared from this low altitude than planned, mission controllers now can afford to allocate some of the spacecraft's data storage and interplanetary radio transmissions to visible spectra in exchange for limiting the infrared to a few select targets. In addition, a device in the infrared spectrometer that lowers the sensor's temperature to -307 degrees Fahrenheit (-188 degrees Celsius) is showing signs of age. (We saw here that the sensor can detect heat. So to avoid interference from its own heat, it needs to be cooled.) Its symptoms are not a surprise, given that the instrument has acquired far, far more data at Vesta and Ceres than it was designed for. It is continuing to function quite productively, but now its use is being curtailed. Dawn LAMO Image 95 [Image] Dawn took this picture of canyons in Ezinu Crater from an altitude of 240 miles (385 kilometers) on April 17. (Ezinu was a Sumerian goddess of grain.) Full image and caption. Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA One of the mission's objectives was to photograph 80 percent of Ceresâ vast landscape with a resolution of 660 feet (200 meters) per pixel. Dawn has now photographed nearly the entirety (99.9 percent) with a resolution of 120 feet (35 meters) per pixel. The adventurer has shown us 25 percent more terrain than planned with 5.7 times the clarity. We can see detail 830 times sharper than the Hubble Space Telescope revealed. What is the value of that much detail? The more detailed the portrait, the better understanding geologists can obtain. Imagine the difference (not only visually but also emotionally and socially) between seeing a person at the opposite end of a soccer field and seeing them from five inches (12 centimeters) away. The pictures speak quite eloquently (and succinctly) for themselves, but let's take a look at one of the many uses of these sharp photographs: determining the age of geological features. In December, we gave an approximate age of 80 million years for Occator Crater, site of the famous "bright spots" (or famously bright spots). It takes more than an experienced geological eye to estimate such an age. [Image] Occator Crater is shown in this mosaic of photos Dawn took at its lowest altitude of 240 miles (385 kilometers). The crater is 57 miles (92 kilometers) in diameter. Go to the full image to see exquisite details of the bright areas as well as fractures in the crater floor and other intriguing features. Note how few craters are within Occator or the area around it. Scientists can translate the number and size of craters into an age. From pictures taken at higher altitudes, they estimate Occator is 80 million years old, as explained below. That age will be refined with these sharper pictures, which reveal smaller craters. Full image and caption. Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA/PSI Now don't forget that we are trying to ascertain the age, but we are going to get there on a long and winding path, mostly because it's an opportunity to touch on some fun and interesting topics. To begin, we go back in time, not quite 80 million years, to the Apollo program. Astronauts returned from the moon with many treasures, including 842 pounds (382 kilograms) of lunar material collected on six missions. In addition, three Soviet robotic Luna spacecraft came back with a total of 11 ounces (0.3 kilograms). Earth's total inventory of lunar samples is larger. By comparing the chemical composition of that material with a great many meteorites, scientists have identified nearly 120 pounds (54 kilograms) of meteorites that were blasted from the moon by asteroid impacts and then landed on our

[meteorite-list] Searchable Land
Many are concerned about what land remains searchable and how to find out federal land boundaries here in the United States. You can get this information directly from the BLM. You will need to get a Google Earth overlay from them in order to plot federally owned land areas. Please obtain the overlay directly from the BLM as I do not have the time to go through the process. Remember that there is a 10 pound limit and that no meteorites found on this land can be resold or bartered. I provided image links of screen shots to two well-know search areas below. Please note that all of the yellow shaded areas are federally owned and off-limits for commercial purposes: Roach and Ivanpah Dry Lake Areas: http://themeteoritesite.com/adam/FederalLandPrimm.jpg Red Dry Lake: http://themeteoritesite.com/adam/FederalLandRedDryLake.jpg Private Land: Then there is the subject of searchable private land which is intermingled with federal and state land. I have noticed a trend that land owners are becoming increasingly protective of their properties since their constitutional rights are being challenged with constant regularity. Take the privately-owned 400 acre property in the middle of Area 51 for example. The only thing that has protected their property thus far from the government are mining patents that give them supreme ownership rights over the government, the way our smart forefathers intended. One land owner was even jailed in Oregon for collecting rain water that fell on his property. If he had a land patent with intact title instead of a warranty deed, he would have been protected since he would have maintained title to the center of the Earth to infinity into the space above his property. It is pretty sad that our government even claims rainwater! They may place rain gauges on farms in California so that they can charge for the water? http://www.huffingtonpost.com/2012/08/16/gary-harrington-oregon-water-rainwater_n_1784378.html What does this have to do with meteorite hunting? The answer is that you better seek permission and do not be surprised if your request is denied. I saw a no trespassing sign that read, "Note, This Property Is Protected by UNITED STATES LAND PATENT. ", "THE RIGHT TO EXCLUDE ANYONE, EVEN THE GOVERNMENT, OR LAW ENFORCEMENT IS A FUNDAMENTAL, CONSTITUTIONAL RIGHT, SET IN LAW, TO WIT: And Another sign on rare patented land read, "The intruder who enters clothed in the robes of authority in broad daylight commits no less an invasion of property rights than if he sneaks in the night wearing a burglar's mask." I would be afraid to ask permission or enter either one of these properties. I am still in the very expensive learning process myself and have focused my attention to private property acquisition and how to seek permission to search other private property. I was extremely fortunate to purchase a property with a U.S. president (Woodrow Wilson) signed serial land patient with the title 100% intact. It cost a small fortune to have a title document research company and lawyers establish a complete title abstract. Finding this property is like winning the lottery to me and I will go to any length and expense to protect my land and all other rights including business contracts and intellectual properties as anyone who has gone against me has found out. Images of BLM land surrounding one of my patented properties in Washoe County, Nevada: http://themeteoritesite.com/adam/CherryCreekLandIsland-a.jpg http://themeteoritesite.com/adam/CherryCreekLandIsland-b.jpg Note that it is completely surrounded by federal land. They have to provide access to my property since I have supreme rights that are guaranteed forever. Fortunately there are several roads leading to the property that are protected forever as well so if the land is nationalized around it, I will still have access. Another nice thing is that the ownership rights are so supreme on this type of land that liens can never be brought against it. Land Patent to my property Serial Number 401771 signed by the President of the United States, his secretary and the recorder of the General Land Office: http://themeteoritesite.com/adam/LandPatent.JPG Here is a case of somebody taking patented land ownership to an extreme. He created his own micro-country (5 acres)here in Nevada in the same county as my property. Nevada recognizes his sovereignty and I find it very entertaining. https://en.wikipedia.org/wiki/Republic_of_Molossia https://www.ksl.com/?sid=26342238 Anyway, I wanted to move onto a another subject instead of the complete nonsense which has been plaguing the list for the last several days.

Re: [meteorite-list] In regards to NWA 10495
Adam, If you do to want to read nonsense, you should not write nonsense! Your written accusations of libel is libel in itself against me. I highly suggest you stop while you are behind! Everybody knows you AND Jeff Kroschell were/are partners and the ones who began the project. You dropped the ball and I picked it up years after you couldn't do it. I rescued the 'mission' and carried the ball across the finish line. Almost everyone is happy except YOU! YOU will never be happy unless you are writing 'nonsense' on the List. Go spend all of the money I put in yours (and hopefully Jeff's family's) pocket and quit throwing it away on wasteful things!
