    Detection of silica-rich deposits on Mars (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-05-24
    Description: Mineral deposits on the martian surface can elucidate ancient environmental conditions on the planet. Opaline silica deposits (as much as 91 weight percent SiO2) have been found in association with volcanic materials by the Mars rover Spirit. The deposits are present both as light-toned soils and as bedrock. We interpret these materials to have formed under hydrothermal conditions and therefore to be strong indicators of a former aqueous environment. This discovery is important for understanding the past habitability of Mars because hydrothermal environments on Earth support thriving microbial ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Squyres, S W -- Arvidson, R E -- Ruff, S -- Gellert, R -- Morris, R V -- Ming, D W -- Crumpler, L -- Farmer, J D -- Marais, D J Des -- Yen, A -- McLennan, S M -- Calvin, W -- Bell, J F 3rd -- Clark, B C -- Wang, A -- McCoy, T J -- Schmidt, M E -- de Souza, P A Jr -- New York, N.Y. -- Science. 2008 May 23;320(5879):1063-7. doi: 10.1126/science.1155429.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Astronomy, Space Sciences Building, Cornell University, Ithaca, NY 14853, USA. squyres@astro.cornell.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18497295" target="_blank"〉PubMed〈/a〉

    Exploration of Victoria crater by the Mars rover Opportunity (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-05-23
    Description: The Mars rover Opportunity has explored Victoria crater, an approximately 750-meter eroded impact crater formed in sulfate-rich sedimentary rocks. Impact-related stratigraphy is preserved in the crater walls, and meteoritic debris is present near the crater rim. The size of hematite-rich concretions decreases up-section, documenting variation in the intensity of groundwater processes. Layering in the crater walls preserves evidence of ancient wind-blown dunes. Compositional variations with depth mimic those approximately 6 kilometers to the north and demonstrate that water-induced alteration at Meridiani Planum was regional in scope.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Squyres, S W -- Knoll, A H -- Arvidson, R E -- Ashley, J W -- Bell, J F 3rd -- Calvin, W M -- Christensen, P R -- Clark, B C -- Cohen, B A -- de Souza, P A Jr -- Edgar, L -- Farrand, W H -- Fleischer, I -- Gellert, R -- Golombek, M P -- Grant, J -- Grotzinger, J -- Hayes, A -- Herkenhoff, K E -- Johnson, J R -- Jolliff, B -- Klingelhofer, G -- Knudson, A -- Li, R -- McCoy, T J -- McLennan, S M -- Ming, D W -- Mittlefehldt, D W -- Morris, R V -- Rice, J W Jr -- Schroder, C -- Sullivan, R J -- Yen, A -- Yingst, R A -- New York, N.Y. -- Science. 2009 May 22;324(5930):1058-61. doi: 10.1126/science.1170355.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Astronomy, Space Sciences Building, Cornell University, Ithaca, NY 14853, USA. squyres@astro.cornell.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19461001" target="_blank"〉PubMed〈/a〉

    In situ evidence for an ancient aqueous environment at Meridiani Planum, Mars (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-04
    Description: Sedimentary rocks at Eagle crater in Meridiani Planum are composed of fine-grained siliciclastic materials derived from weathering of basaltic rocks, sulfate minerals (including magnesium sulfate and jarosite) that constitute several tens of percent of the rock by weight, and hematite. Cross-stratification observed in rock outcrops indicates eolian and aqueous transport. Diagenetic features include hematite-rich concretions and crystal-mold vugs. We interpret the rocks to be a mixture of chemical and siliciclastic sediments with a complex diagenetic history. The environmental conditions that they record include episodic inundation by shallow surface water, evaporation, and desiccation. The geologic record at Meridiani Planum suggests that conditions were suitable for biological activity for a period of time in martian history.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Squyres, S W -- Grotzinger, J P -- Arvidson, R E -- Bell, J F 3rd -- Calvin, W -- Christensen, P R -- Clark, B C -- Crisp, J A -- Farrand, W H -- Herkenhoff, K E -- Johnson, J R -- Klingelhofer, G -- Knoll, A H -- McLennan, S M -- McSween, H Y Jr -- Morris, R V -- Rice, J W Jr -- Rieder, R -- Soderblom, L A -- New York, N.Y. -- Science. 2004 Dec 3;306(5702):1709-14.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Astronomy, Cornell University, Ithaca, NY 14853, USA. squyres@astrosun.tn.cornell.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15576604" target="_blank"〉PubMed〈/a〉

    Atmospheric imaging results from the Mars exploration rovers: Spirit and Opportunity (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-04
    Description: A visible atmospheric optical depth of 0.9 was measured by the Spirit rover at Gusev crater and by the Opportunity rover at Meridiani Planum. Optical depth decreased by about 0.6 to 0.7% per sol through both 90-sol primary missions. The vertical distribution of atmospheric dust at Gusev crater was consistent with uniform mixing, with a measured scale height of 11.56 +/- 0.62 kilometers. The dust's cross section weighted mean radius was 1.47 +/- 0.21 micrometers (mm) at Gusev and 1.52 +/- 0.18 mm at Meridiani. Comparison of visible optical depths with 9-mm optical depths shows a visible-to-infrared optical depth ratio of 2.0 +/- 0.2 for comparison with previous monitoring of infrared optical depths.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lemmon, M T -- Wolff, M J -- Smith, M D -- Clancy, R T -- Banfield, D -- Landis, G A -- Ghosh, A -- Smith, P H -- Spanovich, N -- Whitney, B -- Whelley, P -- Greeley, R -- Thompson, S -- Bell, J F 3rd -- Squyres, S W -- New York, N.Y. -- Science. 2004 Dec 3;306(5702):1753-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Texas A&M University, College Station, TX 77843, USA. lemmon@tamu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15576613" target="_blank"〉PubMed〈/a〉

    Wind-related processes detected by the Spirit Rover at Gusev Crater, Mars (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-08-07
    Description: Wind-abraded rocks, ripples, drifts, and other deposits of windblown sediments are seen at the Columbia Memorial Station where the Spirit rover landed. Orientations of these features suggest formative winds from the north-northwest, consistent with predictions from atmospheric models of afternoon winds in Gusev Crater. Cuttings from the rover Rock Abrasion Tool are asymmetrically distributed toward the south-southeast, suggesting active winds from the north-northwest at the time (midday) of the abrasion operations. Characteristics of some rocks, such as a two-toned appearance, suggest that they were possibly buried and exhumed on the order of 5 to 60 centimeters by wind deflation, depending on location.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Greeley, R -- Squyres, S W -- Arvidson, R E -- Bartlett, P -- Bell, J F 3rd -- Blaney, D -- Cabrol, N A -- Farmer, J -- Farrand, B -- Golombek, M P -- Gorevan, S P -- Grant, J A -- Haldemann, A F C -- Herkenhoff, K E -- Johnson, J -- Landis, G -- Madsen, M B -- McLennan, S M -- Moersch, J -- Rice, J W Jr -- Richter, L -- Ruff, S -- Sullivan, R J -- Thompson, S D -- Wang, A -- Weitz, C M -- Whelley, P -- New York, N.Y. -- Science. 2004 Aug 6;305(5685):810-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geological Sciences, Arizona State University, Box 871404, Tempe, AZ 85287-1404, USA.

    Morphology and composition of the surface of Mars: Mars Odyssey THEMIS results (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-06-07
    Description: The Thermal Emission Imaging System (THEMIS) on Mars Odyssey has produced infrared to visible wavelength images of the martian surface that show lithologically distinct layers with variable thickness, implying temporal changes in the processes or environments during or after their formation. Kilometer-scale exposures of bedrock are observed; elsewhere airfall dust completely mantles the surface over thousands of square kilometers. Mars has compositional variations at 100-meter scales, for example, an exposure of olivine-rich basalt in the walls of Ganges Chasma. Thermally distinct ejecta facies occur around some craters with variations associated with crater age. Polar observations have identified temporal patches of water frost in the north polar cap. No thermal signatures associated with endogenic heat sources have been identified.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Christensen, Philip R -- Bandfield, Joshua L -- Bell, James F 3rd -- Gorelick, Noel -- Hamilton, Victoria E -- Ivanov, Anton -- Jakosky, Bruce M -- Kieffer, Hugh H -- Lane, Melissa D -- Malin, Michael C -- McConnochie, Timothy -- McEwen, Alfred S -- McSween, Harry Y Jr -- Mehall, Greg L -- Moersch, Jeffery E -- Nealson, Kenneth H -- Rice, James W Jr -- Richardson, Mark I -- Ruff, Steven W -- Smith, Michael D -- Titus, Timothy N -- Wyatt, Michael B -- New York, N.Y. -- Science. 2003 Jun 27;300(5628):2056-61.

    Publication Date: 2004-08-07
    Description: The magnetic properties experiments are designed to help identify the magnetic minerals in the dust and rocks on Mars-and to determine whether liquid water was involved in the formation and alteration of these magnetic minerals. Almost all of the dust particles suspended in the martian atmosphere must contain ferrimagnetic minerals (such as maghemite or magnetite) in an amount of approximately 2% by weight. The most magnetic fraction of the dust appears darker than the average dust. Magnetite was detected in the first two rocks ground by Spirit.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bertelsen, P -- Goetz, W -- Madsen, M B -- Kinch, K M -- Hviid, S F -- Knudsen, J M -- Gunnlaugsson, H P -- Merrison, J -- Nornberg, P -- Squyres, S W -- Bell, J F 3rd -- Herkenhoff, K E -- Gorevan, S -- Yen, A S -- Myrick, T -- Klingelhofer, G -- Rieder, R -- Gellert, R -- New York, N.Y. -- Science. 2004 Aug 6;305(5685):827-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Planetary Science, Danish Space Research Institute and Niels Bohr Institute for Astronomy, Physics and Geophysics, University of Copenhagen, DK-2100 Copenhagen, Denmark. preben@fys.ku.dk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15297664" target="_blank"〉PubMed〈/a〉

    Basaltic rocks analyzed by the Spirit Rover in Gusev Crater (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-08-07
    Description: The Spirit landing site in Gusev Crater on Mars contains dark, fine-grained, vesicular rocks interpreted as lavas. Pancam and Mini-Thermal Emission Spectrometer (Mini-TES) spectra suggest that all of these rocks are similar but have variable coatings and dust mantles. Magnified images of brushed and abraded rock surfaces show alteration rinds and veins. Rock interiors contain 〈/=25% megacrysts. Chemical analyses of rocks by the Alpha Particle X-ray Spectrometer are consistent with picritic basalts, containing normative olivine, pyroxenes, plagioclase, and accessory FeTi oxides. Mossbauer, Pancam, and Mini-TES spectra confirm the presence of olivine, magnetite, and probably pyroxene. These basalts extend the known range of rock compositions composing the martian crust.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McSween, H Y -- Arvidson, R E -- Bell, J F 3rd -- Blaney, D -- Cabrol, N A -- Christensen, P R -- Clark, B C -- Crisp, J A -- Crumpler, L S -- Des Marais, D J -- Farmer, J D -- Gellert, R -- Ghosh, A -- Gorevan, S -- Graff, T -- Grant, J -- Haskin, L A -- Herkenhoff, K E -- Johnson, J R -- Jolliff, B L -- Klingelhoefer, G -- Knudson, A T -- McLennan, S -- Milam, K A -- Moersch, J E -- Morris, R V -- Rieder, R -- Ruff, S W -- De Souza, P A Jr -- Squyres, S W -- Wanke, H -- Wang, A -- Wyatt, M B -- Yen, A -- Zipfel, J -- New York, N.Y. -- Science. 2004 Aug 6;305(5685):842-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Planetary Sciences, University of Tennessee, Knoxville, TN 37996-1410, USA. mcsween@utk.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15297668" target="_blank"〉PubMed〈/a〉

    Details
    Publication Date: 2004-08-07
    Description: The Mars Exploration Rover Spirit has traversed a fairly flat, rock-strewn terrain whose surface is shaped primarily by impact events, although some of the landscape has been altered by eolian processes. Impacts ejected basaltic rocks that probably were part of locally formed lava flows from at least 10 meters depth. Some rocks have been textured and/or partially buried by windblown sediments less than 2 millimeters in diameter that concentrate within shallow, partially filled, circular impact depressions referred to as hollows. The terrain traversed during the 90-sol (martian solar day) nominal mission shows no evidence for an ancient lake in Gusev crater.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Grant, J A -- Arvidson, R -- Bell, J F 3rd -- Cabrol, N A -- Carr, M H -- Christensen, P -- Crumpler, L -- Des Marais, D J -- Ehlmann, B L -- Farmer, J -- Golombek, M -- Grant, F D -- Greeley, R -- Herkenhoff, K -- Li, R -- McSween, H Y -- Ming, D W -- Moersch, J -- Rice, J W Jr -- Ruff, S -- Richter, L -- Squyres, S -- Sullivan, R -- Weitz, C -- New York, N.Y. -- Science. 2004 Aug 6;305(5685):807-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Earth and Planetary Studies, National Air and Space Museum, Smithsonian Institution, Washington, DC 20560, USA. grantj@nasm.si.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15297659" target="_blank"〉PubMed〈/a〉
