Integrated analyses of Thermal Emission Imaging System (THEMIS) IR, Context Camera (CTX), and Mars Orbiter Laser Altimeter (MOLA) data sets have been used to characterize the western flank Martian volcano Alba Mons, which hosts a prominent population lava tube systems. Identification mapping systems is based on both morphologic topographic analyses, including presence chains collapse depression...

The amidohydrolase superfamily has remarkable functional diversity, with considerable structural and functional annotation of known sequences. In microbes, the recent evolution of several members of this family to catalyze the breakdown of environmental xenobiotics is not well understood. An evolutionary transition from binuclear to mononuclear metal ion coordination at the active sites of thes...

We describe our initial experiences producing controlled digital elevation models (DEMs) of Mars with horizontal resolutions of ≤10 m and vertical precisions of ≤2 m. Such models are of intense interest at all phases of Mars exploration and scientific investigation, from the selection of safe landing sites to the quantitative analysis of the morphologic record of surface processes. Topomapping ...

The pushbroom scanner HRSC (High Resolution Stereo Camera) onboard the European Mars Express mission is orbiting the planet Mars since January 2004 and delivers stereoscopic imagery with five panchromatic and four colour channels. This paper describes the process of improving the exterior orientation of the HRSC which is needed in order to derive high quality products such as high resolution Di...

Introduction: The possible presence of confined bodies of standing water on early Mars has been postulated for many years, both as large oceans [e.g., 1-5] and as lakes associated with impact crater or intercrater basins [e.g., 6-10]. The northern ocean hypothesis was tested using Mars Orbiter Laser Altimeter (MOLA) elevations along two suggested shorelines, resulting in a fairly poor geopotent...

Mars Orbiter Camera (MOC) images and Mars Orbiter Laser Altimeter (MOLA) data on the Mars Global Surveyor (MGS) spacecraft show evidence for three catastrophic outflow channels around the Cerberus Plains region, Mars. The morphologies seen in MOC images located within channels seen in gridded MOLA topography are similar to those found in catastrophic flood terrains on Earth, such as the Channel...
