[meteorite-list] Rosetta Science Working Team Dedication to Deceased Colleagues
http://blogs.esa.int/rosetta/2015/09/28/rosetta-science-working-team-dedication-to-deceased-colleagues/ Rosetta Science Working Team dedication to deceased colleagues Guest blog post by Matt Taylor, Rosetta Project Scientist. September 28, 2015 At the most recent Rosetta Science Working Team meeting, held in Gottingen Germany in September 2015, a number of new science investigations were discussed, along with updates on on-going studies of Comet 67P/Churyumov-Gerasimenko and its environment. This growing body of science and discovery has only been made possible through the dedication of hundreds of scientists and engineers across the globe, who have worked or still work on the mission. For a project that has been going for almost 30 years, it is also regrettably inevitable that a few members of this large team have been outlived by the mission, including some who unfortunately did not live to appreciate the main comet phase. As a token of deep gratitude and thanks, the Rosetta SWT has dedicated the upcoming special issue of scientific papers in Astronomy & Astrophysics to everyone who has worked on the mission, including those who continue to work on the mission, but especially those colleagues who have passed away. As part of this recognition, the SWT has also dedicated two features on the comet to two esteemed colleagues who have passed away in recent years. These features are the C. Alexander Gate, found on the smaller lobe, dedicated to Dr Claudia J. Alexander, the US Rosetta Project Scientist who passed away in July this year, and the A. Coradini Gate, located on the larger lobe, after Dr Angioletta Coradini, the former Principal Investigator of the VIRTIS instrument, who passed away in September 2011. The two features were chosen for their prominence on Comet 67P/C-G, and for their very distinctive and striking gate-like appearances, considered to be highly appropriate monuments for our absent colleagues. Matt also announced the dedication during the opening ceremony of the European Planetary Science Congress today. __ Visit our Facebook page https://www.facebook.com/meteoritecentral and 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] Hitchhiking to Mars
http://www.nasa.gov/feature/ames/hitchhiking-to-mars Hitchhiking to Mars Story by Gianine M. Figliozzi, Space Biosciences Division, Ames Research Center September 24, 2014 [NOTE: During the experiment the public can watch the progress of the flight unfold by following the links to Fort Sumner Operations from NASAs Columbia Scientific Balloon Facility website at: http://towerfts.csbf.nasa.gov/] Could some of the hardiest bacteria on Earth hitchhike on a Journey to Mars and survive after landing in a new world? NASA researchers intend to find out. A helium-filled scientific balloon will soon carry bacteria to the edge of space - Earth's stratosphere - exposing them to conditions similar to those found on the surface of Mars. NASA researchers will measure how long the bacteria can endure up there, and they also will study the biological underpinnings of bacterial survival in harsh conditions. Earth's stratosphere is an extreme environment. Situated above 99 percent of Earth's protective atmosphere, conditions are dry, cold, and bathed with intense ultraviolet solar radiation. The air pressure is so low it's nearly a vacuum. For these reasons, Earth's stratosphere is a great stand-in for the surface of Mars. "If we want to discover life on other planets we need to know if we are introducing Earth life as we explore,' said David J. Smith, scientist in the Space Biosciences Division at NASA's Ames Research Center, Moffett Field, California, and principal investigator for the study. "There are terrestrial microorganisms that can survive space-like conditions. We know some of these same microorganisms are onboard robotic spacecraft so we need to be able to predict what will happen when they get to Mars." A specialized hardware system that will be used for the study, Exposing Microorganisms in the Stratosphere (E-MIST), was developed at NASA's Kennedy Space Center in Florida. The E-MIST system was successfully flight tested during a five hour balloon flight in 2014. A report on the test flight was published in the December 2014 issue of Gravitational And Space Research. Following this successful validation of the E-MIST system, the first full science mission using the E-MIST system is planned to launch from NASAs Columbia Scientific Balloon Facility in Fort Sumner, New Mexico on September 26. During this mission, similar to the 2014 test flight, the balloon will ascend to altitudes upward of 120,000 feet. "This weekend's flight will be a long duration float in the stratosphere" said Smith. With the extended mission time, the researchers expect to expose the bacteria to the Mars analog environmental conditions for separate intervals of six, 12, 18 and 24 hours. 'I suspect the bacteria will survive, but we just don't know until we fly them up there and take a look afterwards in our lab," said Smith. Before launch, NASA researchers will load bacteria samples into specialized containers that can be opened or closed during flight by the E-MIST system. Launching with closed containers will protect the bacteria from the elements during ascent to Earth's stratosphere. Once the balloon reaches a target altitude, the containers that hold the samples of bacteria will open. At a series of specified time points, each container will close. To terminate the flight, an explosive charge will detonate, tearing a hole in the balloon. E-MIST and other science payloads attached to the balloon's gondola will return to Earth under a parachute, where waiting researchers will recover biological samples for analysis. The E-MIST hardware system was built with funding from Rocket University, a training program developed by Kennedy's Engineering and Technology Directorate and supported by the NASA Office of the Chief Engineer. The E-MIST 2015 science mission is supported by the Core Technical Capabilities Special Studies project at NASA's Kennedy Space Center in Florida; the NASA Balloon Program Office at NASA's Wallops Flight Facility, Wallops Island, Va.; and NASA's Space Biology Project at Ames. Balloon launches are sensitive to local weather conditions and the launch time may vary. Whatever the exact time the balloon takes flight, "I'll be watching online from my office, and so can anyone else with a computer," said Smith. During the experiment the public can watch the progress of the flight unfold by following the links to Fort Sumner Operations from NASA's Columbia Scientific Balloon Facility website at: http://towerfts.csbf.nasa.gov/ For more information about NASA's scientific balloon program watch the video "B-Line to Space: The Scientific Ballooning Story." __ Visit our Facebook page https://www.facebook.com/meteoritecentral and 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] Mars Rover Opportunity Update: September 16-22, 2015
http://mars.nasa.gov/mer/mission/status.html#opportunity OPPORTUNITY UPDATE: Rover's Current Location Makes Communications a Challenge - sols 4140-4146, September 16, 2015-September 22, 2015: Opportunity is within 'Marathon Valley' on the west rim of Endeavour Crater conducting a walk-about survey for clay minerals. The rover's current location within Marathon Valley with its high walls to the north and west presents a challenge for low-elevation Ultra-High-Frequency (UHF) relay passes to the west. On Sol 4141 (Sept. 17, 2015), no data were received as the orbiter's flight path was below the elevation on the valley ridgeline. On that sol, the rover did successfully perform an in-situ science campaign on the surface target, 'Pvt. George Gibson' that included a Microscopic Imager (MI) mosaic and the placement of the Alpha Particle X-ray Spectrometer (APXS). Some of those data were received on subsequent sols. On Sol 4144 (Sept. 20, 2015), another MI mosaic was taken and the robotic armed stowed for a future drive. Once again, the high ridgeline of the valley obscured the low-elevation pass on Sol 4145 (Sept. 21, 2015), and little data were received. On Sol 4146 (Sept. 22, 2015), Opportunity was configured from RAM-only operation to Flash as a planned test of the non-volatile storage system. The drive on that sol completed successfully, but an amnesia event with Flash prevented a return of drive-related data on that sol. Those data are expected to be received on subsequent sols. The plan forward is to continue to operate in Flash for one week in order to gain information and statistics on the state of the Flash storage system. As of Sol 4146 (Sept. 22, 2015), the solar array energy production was 335 watt-hours with an atmospheric opacity (Tau) of 0.539 and a solar array dust factor of 0.569. Total odometry is (26.43 miles) 42.53 kilometers, more than a marathon. __ Visit our Facebook page https://www.facebook.com/meteoritecentral and 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] Dawn Journal - September 27, 2015
http://dawnblog.jpl.nasa.gov/2015/09/27/dawn-journal-september-27-2/ Dawn Journal by Dr. Marc Rayman September 27, 2015 Dear Dawnniversaries, Eight years ago today, Dawn was gravitationally bound to a planet. It was conceived and built there by creatures curious and bold, with an insatiable yearning to reach out and know the cosmos. Under their guidance, it left Earth behind as its Delta rocket dispatched it on an ambitious mission to explore two of the last uncharted worlds in the inner solar system. As Earth continued circling the sun once a year, now having completed eight revolutions since its celestial ambassador departed, Dawn has accomplished a remarkable interplanetary journey. The adventurer spent most of its anniversaries powering its way through the solar system, using its advanced and uniquely capable ion propulsion system to reshape its orbit around the sun. On its way to the main asteroid belt, it sailed past Mars, taking some of the that red planet's orbital energy to boost its own solar orbit. On its fourth anniversary, the probe was locked in orbit around the giant protoplanet Vesta, the second most massive object between Mars and Jupiter. Dawn's pictures and other data showed it to be a complex, fascinating world, more closely related to the terrestrial planets (including one on which it began its mission and another from which it stole some energy) than to the much smaller asteroids. Today, on the eighth anniversary of venturing into the cosmos, Dawn is once again doing what it does best. In the permanent gravitational embrace of dwarf planet Ceres, orbiting at an altitude of 915 miles (1,470 kilometers), Dawn is using its suite of sophisticated sensors to scrutinize this mysterious, alien orb. Ceres was the first dwarf planet ever sighted (and was called a planet for more than a generation after its discovery), but it had to wait more than two centuries before Earth accepted its celestial invitation. The only spacecraft ever to orbit two extraterrestrial destinations, this interplanetary spaceship arrived at Ceres in March to take up residence. Although this is the final anniversary during its scheduled primary mission, Dawn will remain in orbit around its new home far, far into the future. Later this year it will spiral down to its fourth and final orbital altitude at about 230 miles (375 kilometers). Once there, it will record spectra of neutrons, gamma rays, and visible and infrared light, measure the distribution of mass inside Ceres, and take pictures. Then when it exhausts its supply of hydrazine next year, as it surely will, the mission will end. We have discussed before that despite the failure of two reaction wheels, devices previously considered indispensable for the expedition, the hardy ship has excellent prospects now for fulfilling and even exceeding its many goals in exploring Ceres. Last month we described the plans for Dawn's penultimate mapping phase at the dwarf planet, and it is going very well. The probe is already more than halfway through this third orbital phase at Ceres, which is divided into six mapping cycles. Each 11-day cycle requires a dozen flights over the illuminated hemisphere to allow the camera to map the entire surface. Each map is made by looking at a different angle. Taken together then, they provide stereo views, so scientists gain perspectives that allow them to construct topographical maps. The camera's internal computer detected an unexpected condition in the third cycle of this phase, and that caused the loss of some of the pictures. But experienced mission planners had designed all of the major mapping phases (summarized here) with more observations than are needed to meet their objectives, so the deletion of those images was not significant. At this moment, the spacecraft is nearing the end of its fourth mapping cycle, making its tenth flight over the side of Ceres lit by the sun. You can follow Dawn's progress by using your own interplanetary spaceship to snoop into its activities in orbit around the distant world, by tapping into the radio signals beamed back and forth across the solar system between Dawn and the giant antennas of NASA's Deep Space Network, or by checking the frequent mission status reports. You also can see the marvelous sights by visiting the Ceres image gallery. Among the most captivating is Occator crater (see the picture below). As the spacecraft has produced ever finer pictures this year, starting with its distant observations in January, the light reflecting from the interior of this crater has dazzled us. The latest pictures show 260 times as much detail. Dawn has transformed what was so recently just a bright spot into a complex and beautiful gleaming landscape. Last month we asked what these mesmerizing features would reveal when photographed from this the present altitude, and now we know. Scientists are continuing to analyze Dawn's

Re: [meteorite-list] Where do I find a high end buyer 120kg+ Campo Del Cielo meteorite
Hi Bill, An interesting post. I would think that most high end clients and serious collectors would subscribe to this list. So perhaps you have already reached them. My questions for you are why do you think your rock would interest a "high end client"? Where was it found? When was it found? Did you find it? The answers to these questions may make it more interesting. However it is a common meteorite (albeit a larger sample). Your in situ photos add a little interest to the rock. The question is do they add enough? I can't imagine that you would be able to put together a client base of "high end" clients without first having a history of selling desirable meteorites. Perhaps your best bet is to pay someone to get access to their "high end" clients. The easiest way to do that would be to consigning your rock to an auction house with a successful track record of selling meteorites.
