AB: The Mars Reconnaissance Orbiter's (MRO) High Resolution Imaging Science Experiment (HiRISE) began acquiring data in the fall of 2006. Some of the images of the past year of operations include support for the 2009 Mars Science Laboratory (MSL) potential landing sites, which were proposed at the first landing site workshop in October of 2006. There are 28 proposed sites that were prioritized at the first workshop and they are located across elevations and latitudes ranging from -6 km to approximately +1 km, and 29.3°N to 48.5°S respectively. These sites emphasize a range of science themes including mineralogy (i.e. phyllosilicates, sulfates, or hematite), layered materials, or presence of fluvial, erosional or depositional landforms. Each site was originally proposed with a 20 km landing ellipse in an area that appeared smooth and flat in pre-HiRISE images. Many of the sites are "go to" sites where there is a proposed landing ellipse adjacent to a nearby science target of interest. HiRISE has acquired images at ~30 cm/pixel for all the proposed sites, including a few additional images of the northern hemisphere landing ellipses at low sun, used to better constrain the distribution of slopes at small scales. Each HiRISE image is approximately 6 km wide by at least 10 km long and includes a 1.2 km-wide blue-green and NIR swath down the middle of the image. For each HiRISE footprint, there is also a co-located Context Image (CTX) and CRISM hyperspectral image. The HiRISE images show a variety of landforms at high resolution, such as layered deposits, dunes, channels, ridges, rocks, polygonal terrain and craters. Each of these sites will be extensively studied to assess the safest landing site, as well as what is best suited to achieving mission science objectives. The acquired images have been released to the PDS and are available to all interested parties, including MSL project and science advocates for the purpose of characterizing potential hazards to safe landing and operations and to assess to science potential of the sites relative to stated mission objectives and planetary protection requirements. http://marsoweb.nas.nasa.gov/landingsites/ http://webgis.wr.usgs.gov/msl/
