[meteorite-list] Comet C/2013 A1 May Postpone India's Mars Mission
http://www.dnaindia.com/scitech/1819996/report-dna-exclusive-comet-mars-isro-s-rs450cr-dream-mission Comet Mars Isro's Rs450cr dream mission Nirad Mudur DNA India April 8, 2013 India's Mars mission is suffering from birth pangs. A comet heading towards the planet could derail Indian Space Research Organisation's (Isro) project, worth Rs450 crore, scheduled to take off in October-November this year. Scientists are now exploring the possibility of postponing the launch to allow the comet to pass by Mars before the spacecraft lands. The comet - C/2013 A1 - is approaching the red planet at a speed of 2 lakh km/hour and has a probability of 1 in 8,000 to strike Mars. As per current trajectory projections, calculated by US' National Aeronautics and Space Administration (Nasa), the comet will be closest to Mars at a distance of 3 lakh km. But the planet will be engulfed in the tail of the comet - extending to millions of kilometres - which will be on Mars' sunward side. The tail of a comet points away from the sun due to radiation effects. The comet poses a problem because no one knows its precise properties, and therefore, the effects it'll leave behind. It was discovered only on January 3 this year by Rob McNaught at the Siding Spring Observatory in Australia. And our mission will reach the planet just a month before the comet's arrival. Isro scientists admit that India's Mars mission will be affected by the comet. One of the main objectives of the mission is to detect methane in the Martian atmosphere with a methane sensor for Mars (MSN). The sensor will be one of the five payloads on board the unmanned spacecraft, which is expected to orbit the planet at an altitude of 500km after covering a journey 5.46 crore km through space in nine months. A senior scientist working on the Mars mission explains how the comet could scuttle the project. Most comets have methane, and there is a good chance that our MSN payload may confuse the methane it detects from the comet as that of Mars and transmit wrong data. Such data will mislead us. Even Nasa is wary. Prof Tushar Prabhu, dean of Bangalore-based Indian Institute of Astrophysics (IIA), agrees that the comet's tail, which is packed with methane, will play the spolier. He hopes that Isro will take a guarded decision on the mission. M Annadurai, Mars mission project director, is non-committal on whether the launch date would be pushed ahead, saying it all boils down to the comet's trajectory. It's too early to say anything right nowbut we are in touch with Nasa scientists on this. Although he neither denies nor confirms the rescheduling, he gave enough hints that the current date - November 27 - of the launch could be changed. Isro had zeroed in on three launch windows for the mission - November 2013-January 2014, January-April 2016; and April-May 2018. Isro scientists are not sure if the launch date could be postponed within the current launch window (November 2013-January2014) or if they'd have to wait till 2016 or 2018. But Prof UR Rao, one of India's staunchest supporters for exploring and colonising Mars and who is also chairman of the governing council of Isro's Ahmedabad-based Physical Research Laboratory (PRL), suggests that we have to take some risks. There is still time [to change plans], says IIA's Prof Prabhu. I hope Isro scientists take the right decision on time. It will be a difficult decision. The presence of methane on Mars is indicative of two things - signs of life or possibilities of chemical reactions, just like on Earth. Methane was faintly detected on Mars a few years ago. But its presence could not confirmed as the Nasa rover then could detect only a larger volume of the gas at a go - about several parts per billion. Prof JN Goswami, director of PRL, says India's MSN payload can detect even faint amounts - 10 parts per billion. The comet has taken even Nasa by surprise. It, too, will send out a craft - MAVEN (Mars Atmosphere and Volatile Evolution) - to study Mars' upper atmosphere in November this year. The launch was planned much ahead of C/2013 A1's discovery and its close Mars fly-by. It will reach the planet around the same time as India's spacecraft. Isro Mars probe, the victim Scheduled to be launched on November 27, 2013 Will carry five payloads, including those to detect methane and hydrogen Will take nine months to reach Mars, which is 54.6 million kilometres away The problem Mars will be within the comet's tail from October 19, 2014, but no one knows for how long This would confuse the spacecraft-borne detectors about the source of the gases they are trying to detect The entire Rs450-crore mission could be affected because the comet's properties could be confused with those of Mars by the spacecraft's sensors __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com

Rover team members reported diverse findings today at the European Geosciences Union 2013 General Assembly, in Vienna. Evidence has strengthened this month that Mars lost much of its original atmosphere by a process of gas escaping from the top of the atmosphere. Curiosity's Sample Analysis at Mars (SAM) instrument analyzed an atmosphere sample last week using a process that concentrates selected gases. The results provided the most precise measurements ever made of isotopes of argon in the Martian atmosphere. Isotopes are variants of the same element with different atomic weights. We found arguably the clearest and most robust signature of atmospheric loss on Mars, said Sushil Atreya, a SAM co-investigator at the University of Michigan, Ann Arbor. SAM found that the Martian atmosphere has about four times as much of a lighter stable isotope (argon-36) compared to a heavier one (argon-38). This removes previous uncertainty about the ratio in the Martian atmosphere from 1976 measurements from NASA's Viking project and from small volumes of argon extracted from Martian meteorites. The ratio is much lower than the solar system's original ratio, as estimated from argon-isotope measurements of the sun and Jupiter. This points to a process at Mars that favored preferential loss of the lighter isotope over the heavier one. Curiosity measures several variables in today's Martian atmosphere with the Rover Environmental Monitoring Station (REMS), provided by Spain. While daily air temperature has climbed steadily since the measurements began eight months ago and is not strongly tied to the rover's location, humidity has differed significantly at different places along the rover's route. These are the first systematic measurements of humidity on Mars. Trails of dust devils have not been seen inside Gale Crater, but REMS sensors detected many whirlwind patterns during the first hundred Martian days of the mission, though not as many as detected in the same length of time by earlier missions. A whirlwind is a very quick event that happens in a few seconds and should be verified by a combination of pressure, temperature and wind oscillations and, in some cases, a decrease is ultraviolet radiation, said REMS Principal Investigator Javier Gómez-Elvira of the Centro de AstrobiologÃa, Madrid. Dust distributed by the wind has been examined by Curiosity's laser-firing Chemistry and Camera (ChemCam) instrument. Initial laser pulses on each target hit dust. The laser's energy removes the dust to expose underlying material, but those initial pulses also provide information about the dust. We knew that Mars
[meteorite-list] Shaking ExoMars
http://www.esa.int/Our_Activities/Space_Science/Shaking_ExoMars Shaking ExoMars European Space Agency 8 April 2013 The structural model of the Entry, Descent and Landing Demonstrator Module, or EDM, of ESA's 2016 ExoMars mission has been subjected to a series of intense shaker tests to simulate the rigours of launching into space. EDM will be launched to Mars together with the Trace Gas Orbiter and will test key landing technologies in preparation for the 2018 ExoMars rover mission and subsequent missions to Mars. The orbiter will search for evidence of methane and other atmospheric gases that could be signatures of active biological or geological processes. It will also act as a relay for EDM and the ExoMars rover, which will search the planet's surface and drill to depths of 2 m, looking for signs of life, past and present. Before being launched to the Red Planet, each component of the mission must undergo thorough testing to certify it for the journey from Earth to the surface of Mars, and for the harsh space environment. EDM arrived at ESTEC, ESA's technical centre in Noordwijk, the Netherlands, in mid-February, on a lorry from the Turin facility of Thales Alenia Space in Italy. After unpacking in one of ESTEC's cleanrooms, it was subjected to a leak-test, to verify the bio-seal between its main structural elements, the aeroshell, front shield and back cover. The bio-seal prevents contamination of the inside of EDM from Earth-borne organisms during ground transportation and testing. After that, EDM has undergone a series of vibration tests on the ESTEC Test Centre Multishaker and QUAD shaker. These intense tests qualify the spacecraft design by ensuring that it will be able to withstand the vibrations it will experience when it lifts off on a Proton rocket in 2016. During the tests, EDM was mounted on a table where it was shaken up and down or from side to side for several minutes over a frequency range of 5 Hz to 2 kHz. Afterwards, another leak demonstrated that the bio-seal had not been degraded by the vibration tests. The EDM structural model has now returned to the Turin factory, where it will undergo further structural testing. This will include tests to simulate entering the martian atmosphere and deploying the module's parachutes. At Mars, EDM will hit the atmosphere at 21 000 km/h, decelerating to just 15 km/h in less than 8 minutes. The ExoMars missions in 2016 and 2018 are being performed by ESA in partnership with Russia's Roscosmos space agency. __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] House-AD: In Honor of Vesta - Dreampiece (only AHOW-an) and Dreambits
Dear collectors, the Meteorite House crew is of the opinion, that in all that Chelyabinsk-hustle it would be unfair to neglect one of our all favorite luminary; Goddess Vesta - now where the Dawn spaceprobe said farewell to her (what a picture!): http://www.nasa.gov/images/content/685735main_pia15678-43_full.jpg Dawn, which had made a pass to her in such an unbeseeming manner, that the wrinkles of the Lady became visible, her pockmarks and the layers of powder she applied to cover them - and that we got the final missing evidence, that some of the rocks in our drawers and cabinets are truly of Vesta's belongings. Therefore we compiled a little piece, wherein specimens for really everyone can be found, from the budget collector, who nevertheless doesn't want cut back in quality to the toppest notch, who has severe problems to find still something substantially new for his/her collection. Four movements we have to play, but we try to keep it short this time, for not taxing your attention span (which is getting shorter and shorter in the FB-ages). 1st) NWA 6475 Cuuutest pearls and real gems, crusted and fresh individuals of a polymict eucrite. (All love them. And don't worry, also the highrollers amassing stones of museums sizes - quite all of them have a feeble for such miniatures! And will set 6475 with caution between their Mini-Camel Dongas and Bilangas). Btw. also internally NWA 6475 has all, a fine polymict EUC needs, even larger carbonaceous inclusions, here an example: http://www.meteoritenhaus.de/img/NWA_6475_end_1_59_g_01.JPG It's our second lot, the first one went so quickly, that nothing was left to advertize here, sorry. Same price. Fresh Individuals (the numbers painted on them are Buhl-numbers from the Meteorite Recon Coll.): A) 1.24g $40 A little bit broken, but in the crack by chance you find a large eucrite-nest. http://www.meteoritenhaus.de/img/NWA_6475_1_24_g_01.JPG http://www.meteoritenhaus.de/img/NWA_6475_1_24_g_02.JPG http://www.meteoritenhaus.de/img/NWA_6475_1_24_g_03.JPG http://www.meteoritenhaus.de/img/NWA_6475_1_24_g_04.JPG B) 1.77g $57 http://www.meteoritenhaus.de/img/NWA_6475_1_77_g_01.JPG http://www.meteoritenhaus.de/img/NWA_6475_1_77_g_02.JPG http://www.meteoritenhaus.de/img/NWA_6475_1_77_g_03.JPG http://www.meteoritenhaus.de/img/NWA_6475_1_77_g_04.JPG C) 1.83g $59 http://www.meteoritenhaus.de/img/NWA_6475_1_83_g_01.JPG http://www.meteoritenhaus.de/img/NWA_6475_1_83_g_02.JPG http://www.meteoritenhaus.de/img/NWA_6475_1_83_g_03.JPG http://www.meteoritenhaus.de/img/NWA_6475_1_83_g_04.JPG D) 1.94g $63 http://www.meteoritenhaus.de/img/NWA_6475_1_94_g_01.JPG http://www.meteoritenhaus.de/img/NWA_6475_1_94_g_02.JPG http://www.meteoritenhaus.de/img/NWA_6475_1_94_g_03.JPG E) 3.31g $107 http://www.meteoritenhaus.de/img/NWA_6475_3_31_g_01.JPG http://www.meteoritenhaus.de/img/NWA_6475_3_31_g_02.JPG http://www.meteoritenhaus.de/img/NWA_6475_3_31_g_03.JPG http://www.meteoritenhaus.de/img/NWA_6475_3_31_g_04.JPG 2nd) Exclusive reference specimens for numbers fetishists. There we'd have to offer as specialty three different eucrites of newer and newest NWA-entries. Exclusive they are inasmuch as these numbers are not available else than through these few references pieces, while the rest of the masses remained in the private collection of the purchasers + at the classifying institutes. Hence stuff and in sizes, which would most probably disproportionally highly paid, if thrown into ebay. However, they are pretty fresh! F) NWA 6730 Bulletin entry: http://www.lpi.usra.edu/meteor/metbull.php?code=54599 A monomict one (monomict eucrites are rarer than polymict ones). Well fresh, note the fusion crust on the edge. Displays two lithologies, one is leopardialic Millbillillie-style, the other coarser (to the left, down). Two grinded slices in a box: 1.97g + 1.21g = 3.18g $59 http://www.meteoritenhaus.de/img/NWA6730_3_18_g_01.JPG http://www.meteoritenhaus.de/img/NWA6730_3_18_g_02.JPG http://www.meteoritenhaus.de/img/NWA6730_3_18_g_03.JPG G) NWA 7705 A polymict eucrite and a true beauty. Nice extra - the finder is given in the Bulletin: http://www.lpi.usra.edu/meteor/metbull.php?code=57152 Elegant - we like especially the faint whitish cumuli clouds of the matrix, giving the view depth and the little black clasts and fragments like a flock of birds playing high in the air. It's only weakly shocked. It's even an idea fresher than the first one, as one can detect by means of the fusion crust. Two grinded reference slices 3.81g + 1.43g = 5.24g $124 http://www.meteoritenhaus.de/img/NWA7705_5_24_g_01.JPG http://www.meteoritenhaus.de/img/NWA7705_5_24_g_02.JPG http://www.meteoritenhaus.de/img/NWA7705_5_24_g_03.JPG H) NWA 7706 http://www.lpi.usra.edu/meteor/metbull.php?code=57153 Remarkably stronger shocked is that new polymict eucrite.
