Young Valley Networks on Mars: Persistent Flow of Water in Lyot Crater, an Amazonian Impact Basin Microenvironment
Introduction: While Amazonian fluvial landforms are not abundant on Mars, remote sensing data have revealed details regarding the role of ice in non-polar regions in the Amazonian. Evidence includes 1) deposits interpreted to be remnants of cold-based glaciers at low-and mid-latitudes [1-6]; 2) mantling deposits interpreted to be a desiccating layer of ground ice [7-8]; 3) laterally-expansive u...

متن کاملAncient impact and aqueous processes at Endeavour Crater, Mars.
The rover Opportunity has investigated the rim of Endeavour Crater, a large ancient impact crater on Mars. Basaltic breccias produced by the impact form the rim deposits, with stratigraphy similar to that observed at similar-sized craters on Earth. Highly localized zinc enrichments in some breccia materials suggest hydrothermal alteration of rim deposits. Gypsum-rich veins cut sedimentary rocks...
متن کاملMars atmosphere. Mars methane detection and variability at Gale crater.
Reports of plumes or patches of methane in the martian atmosphere that vary over monthly time scales have defied explanation to date. From in situ measurements made over a 20-month period by the tunable laser spectrometer of the Sample Analysis at Mars instrument suite on Curiosity at Gale crater, we report detection of background levels of atmospheric methane of mean value 0.69 ± 0.25 parts pe...
