Hundreds of impact craters on Mars contain diverse phyllosilicates, interpreted as excavation products preexisting subsurface deposits following and crater formation. This has been used to argue that the conditions conducive phyllosilicate synthesis, which require presence abundant long-lasting liquid water, were only met early in history planet, during Noachian period (> 3.6 Gy ago), aqueous environments widespread then. Here we test this hypothesis by examining process hydrated minerals...
Refined calibrations of CRISM images are enabling identification smaller deposits unique aqueous materials on Mars that reveal changing environmental conditions at the region surrounding Mawrth Vallis. Through characterization these clay-sulfate assemblages and their association with layered, phyllosilicate units this region, more details geochemical history can be gleaned. A stratigraphy including five distinct mineral horizons is mapped using compositional data from over CTX HRSC imagery...

Abstract We describe the field demonstration of astrobiology instruments and research methods conducted in from Mars Desert Research Station (MDRS) Utah during EuroGeoMars campaign 2009 coordinated by ILEWG, ESA/ESTEC NASA Ames, with contribution academic partners. discuss entire experimental approach determining geological context using remote sensing, situ measurements, sorties sample collection characterization, analysis laboratory, to post advanced laboratory facilities. present...
Abstract. Historic analogue seismograms of the large 1956 Amorgos twin earthquakes which occurred in volcanic arc Hellenic subduction zone (HSZ) were collected, digitized and reanalyzed to obtain refined estimates their depth focal mechanism. In total, 80 records events from 29 European stations collected and, if possible, digitized. addition, bulletins searched for instrument parameters required calculate transfer functions correction. A grid search based on matching historic waveforms...
After more than ten years in orbit at Mars, the coverage from High Resolution Stereo Camera (HRSC) on European Space Agency’s Mars Express is sufficient to begin constructing mosaic products a global scale. We describe our systematic processing procedure and, particular, technique used bring images affected by atmospheric dust into visual consistency with mosaic. outline how same method produce relative colour which shows local differences. demonstrate results and show that techniques may...
After the successful landing of Mars Science Laboratory rover, both NASA and ESA initiated a selection process for potential sites Mars2020 ExoMars missions, respectively. Two ellipses located in Mawrth Vallis region were proposed evaluated during series meetings (three mission five ExoMars). We describe here regional context two as well framework objectives these missions. Key science targets their astrobiological interests are reported. This work confirms that contain multiple past martian...
The installation of planetary and lunar human outposts might be an important step for future solar system exploration by both public space agencies private companies. Humans living working in these artificially created habitats will possibly depend, among other life support approaches, on bio-regenerative systems to produce recycle oxygen water, food. A variety natural resources suitable can readily found Mars, a lesser extent the Moon. Instead launching all (e.g., propellant, food...
Accurate activity classification is essential for the advancement of closed-loop control left ventricular assist devices (LVADs), as it provides necessary feedback to adapt device operation patient’s current state. Therefore, this study aims at using deep neural networks (DNNs) precisely classify these patients. Recordings from 13 LVAD patients were analyzed, including heart rate, flow, and accelerometer data, classifying activities into six states: active, inactive, lying, sitting,...
Acid-sulfate minerals such as jarosite are often used indicators of environmental conditions on Mars. These form in a diverse set environments Earth; however, all known Martian deposits most likely evaporative, from evaporation either groundwater or ponded water. Here, we use the Compact Reconnaissance Imaging Spectrometer for Mars and High-Resolution Science Experiment to report new deposit along southern wall Ius Chasma. The morphology geologic context unique Mars, difficult explain with...
(ABRIDGED) In previous work, two platforms have been developed for testing computer-vision algorithms robotic planetary exploration (McGuire et al. 2004b,2005; Bartolo 2007). The wearable-computer platform has tested at geological and astrobiological field sites in Spain (Rivas Vaciamadrid Riba de Santiuste), the phone-camera a site Malta. this we (i) apply Hopfield neural-network algorithm novelty detection based upon color, (ii) integrate field-capable digital microscope on wearable...
Abstract The circum north-polar Rupes Tenuis unit forms the polar-proximal basal stratigraphical and morphological units that delineate north polar cap between 180° 300°E. In region of mouth Chasma Boreale re-entrant, is likely to extend further southwards into northern plains. This suggested by occurrence isolated remnants have been interpreted as basaltic shield volcanoes, maar craters or mud volcanoes in past. As key elements this study, we assessed quantitative characteristics using...
Abstract We describe an image-comparison technique of Heidemann and Ritter (2008a, b), which uses image compression, is capable of: (i) detecting novel textures in a series images, as well (ii) alerting the user to similarity new previously observed texture. This has been implemented tested using our Astrobiology Phone-cam system, employs Bluetooth communication send images local laptop server field for image-compression analysis. system site displaying heterogeneous suite sandstones,...
Intriguing outcrops in Ius Chasma provide a window into past aqueous processes Valles Marineris, Mars. Hydrous sulfate minerals are abundant throughout this region, but one area includes phyllosilicates, opal, and additional materials with unusual spectral features. This study at Geryon Montes, an east-west horst that divides northern southern canyon, exploits recent advances image calibration feature extraction techniques for analysis of hyperspectral images acquired by the Compact...
