[meteorite-list] NASA's Curiosity Mars Rover Views Striated Ground
http://www.jpl.nasa.gov/news/news.php?release=2014-063 NASA's Curiosity Mars Rover Views Striated Ground Jet Propulsion Laboratory February 26, 2014 [Images] * Martian Landscape With Rock Rows and Mount Sharp * Martian Landscape With Rock Rows and Mount Sharp (Stereo) * Curiosity's View Back After Passing 'Junda' Striations * Panoramic View From West of 'Dingo Gap' * Panoramic View From West of 'Dingo Gap' (Stereo) NASA's Curiosity Mars rover has reached an area where orbital images had piqued researchers' interest in patches of ground with striations all oriented in a similar direction. A close-up look at some of the striations from the rover's Navigation Camera gains extra drama by including Mount Sharp in the background. The lower slopes of that layered mountain are the mission's long-term science destination. The image is online at: http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA17947 The foreground rocks are in an outcrop called Junda, which the rover passed during a drive of 328 feet (100 meters) on Feb. 19. It paused during the drive to take the component images of the scene, then finished the day's drive. A location still ahead, called Kimberley, where researchers plan to suspend driving for a period of science investigations, also features ground with striations. 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.

[meteorite-list] MAVEN Performs 2nd Trajectory Correction Maneuver

Post-maneuver data review shows that TCM-2 went according to plan. This burn lasted approximately 19 seconds and imparted a change in velocity of 68.8 centimeters per second (1.54 mph). The maneuver was used to adjust the ...aim point of MAVEN at its closest approach when it arrives at Mars, so that it can properly enter orbit around the planet. All spacecraft systems continue to show nominal performance. TCM-1 occurred on Dec. 3, 2013. TCM-3 is scheduled for July 23. Upcoming events in March include continuing calibrations and checkouts of various instrument and spacecraft systems. MAVEN is at a distance of 21.2 million kilometers (13.2 million miles) from Earth and 103.7 million kilometers (64.4 million miles) from Mars. The current velocity is 29.44 kilometers per second (65,855 mph) as it moves around the Sun. __ 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] NASA Scientists Find Evidence of Water in Mars Meteorite, Reviving Debate Over Life on Mars
http://www.jpl.nasa.gov/news/news.php?release=2014-065 NASA Scientists Find Evidence of Water in Meteorite, Reviving Debate Over Life on Mars Jet Propulsion Laboratory February 27, 2014 A team of scientists at NASA's Johnson Space Center in Houston and the Jet Propulsion Laboratory in Pasadena, Calif., has found evidence of past water movement throughout a Martian meteorite, reviving debate in the scientific community over life on Mars. In 1996, a group of scientists at Johnson led by David McKay, Everett Gibson and Kathie Thomas-Keprta published an article in Science announcing the discovery of biogenic evidence in the Allen Hills 84001(ALH84001) meteorite. In this new study, Gibson and his colleagues focused on structures deep within a 30-pound (3.7-kilogram) Martian meteorite known as Yamato 000593 (Y000593). The team reports that newly discovered different structures and compositional features within the larger Yamato meteorite suggest biological processes might have been at work on Mars hundreds of millions of years ago. The team's findings have been published in the February issue of the journal Astrobiology. The lead author, Lauren White, is based at the Jet Propulsion Laboratory. Co-authors are Gibson, Thomas-Keprta, Simon Clemett and McKay, all based at Johnson. McKay, who led the team that studied the ALH84001 meteorite, died a year ago. While robotic missions to Mars continue to shed light on the planet's history, the only samples from Mars available for study on Earth are Martian meteorites, said White. On Earth, we can utilize multiple analytical techniques to take a more in-depth look into meteorites and shed light on the history of Mars. These samples offer clues to the past habitability of this planet. As more Martian meteorites are discovered, continued research focusing on these samples collectively will offer deeper insight into attributes which are indigenous to ancient Mars. Furthermore, as these meteorite studies are compared to present day robotic observations on Mars, the mysteries of the planet's seemingly wetter past will be revealed. Analyses found that the rock was formed about 1.3 billion years ago from a lava flow on Mars. Around 12 million years ago, an impact occurred on Mars which ejected the meteorite from the surface of Mars. The meteorite traveled through space until it fell in Antarctica about 50,000 years ago. The rock was found on the Yamato Glacier in Antarctica by the Japanese Antarctic Research Expedition in 2000. The meteorite was classified as a nakhlite, a subgroup of Martian meteorites. Martian meteoritic material is distinguished from other meteorites and materials from Earth and the moon by the composition of the oxygen atoms within the silicate minerals and trapped Martian atmospheric gases. The team found two distinctive sets of features associated with Martian-derived clay. They found tunnel and micro-tunnel structures that thread their way throughout Yamato 000593. The observed micro-tunnels display curved, undulating shapes consistent with bio-alteration textures observed in terrestrial basaltic glasses, previously reported by researchers who study interactions of bacteria with basaltic materials on Earth. The second set of features consists of nanometer- to-micrometer-sized spherules that are sandwiched between layers within the rock and are distinct from carbonate and the underlying silicate layer. Similar spherical features have been previously seen in the Martian meteorite Nakhla that fell in 1911 in Egypt. Composition measurements of the Y000593 spherules show that they are significantly enriched in carbon compared to the nearby surrounding iddingsite layers. A striking observation is that these two sets of features in Y000593, recovered from Antarctica after about 50,000 years residence time, are similar to features found in Nakhla, an observed fall collected shortly after landing. The authors note that they cannot exclude the possibility that the carbon-rich regions in both sets of features may be the product of abiotic mechanisms: however, textural and compositional similarities to features in terrestrial samples, which have been interpreted as biogenic, imply the intriguing possibility that the Martian features were formed by biotic activity. The unique features displayed within the Martian meteorite Yamato 000593 are evidence of aqueous alterations as seen in the clay minerals and the presence of carbonaceous matter associated with the clay phases which show that Mars has been a very active body in its past, said Gibson. The planet is revealing the presence of an active water reservoir that may also have a significant carbon component. The nature and distribution of Martian carbon is one of the major goals of the Mars Exploration Program. Since we have found indigenous carbon in several Mars meteorites, we cannot overstate the importance of having Martian samples available to study in earth-based laboratories. Furthermore, the
