Email: vgulick@mail.arc.nasa.gov INTRODUCTION: The High Resolution Imaging Science Experiment (HiRISE) will fly on the Mars Reconnaissance Orbiter (MRO) mission, planned for launch in August of 2005. HiRISE will investigate deposits and landforms resulting from geologic and climatic processes and is optimized for the evaluation of candidate landing sites. The camera will combine unprecedented resolution (25-50 cm/pixel) and signal-to-noise ratio (SNR >100:1 at all latitudes) with a 5-10km swath width, partial 3- color coverage, and image >2% of Mars at 1m/pixel or better. Stereo image pairs will be acquired over the highest-priority locations allowing for a relative vertical precision of <25 cm. By combining very high resolution and SNR with a large swath width, it is possible to image on a variety of scales down to 1 m, a scale currently afforded only in glimpses by landers. HiRISE will offer such views over any selected region of Mars, providing a bridge between orbital remote sensing and landed missions. The HiRISE team welcomes and will facilitate involvement by the science community and the public. All team members are involved in HiRISE's E/PO effort. User-friendly web tools will be available to both the science community and the public to view/analyze HiRISE images and to submit observation requests. Processed images will be released soon after acquisition to allow everyone to share in the scientific discovery process. Illustration of HiRISE Image (at 400 km) over a portion of the Grand Canyon.

The HiRISE instrument and science team together in Boulder, Colorado., January, 2002. HiRISE images can resolve features diagnostic of origin and process: (a) volcanic fissure vent is diagnostic of the eruptive style; (b) large-scale cross bedding indicates eolian deposition by migrating dunes; (c) boulders exhibiting linear layers suggest lacustrine/pelagic deposition and their angularity indicates minimal transport; (d) polygons marked by sub-meter troughs suggest shallow subsurface ice; rock populations (c and d) indicate style of erosion, and are valuable for assessing landing sites. Each image is sampled at 25 cm/pix with a 10 m scale bar. HiRISE 3-color data will be able to distinguish important classes of materials. Vertical error bars are smaller than symbols. Simulated 200 km orbit Mars images with SNRs of 100:1 (HiRISE) and 25:1 (Brand-X). The magnified region is highlighted in the input image to the left and is 50 x 110 pixels (12.5 m x 27.5 m). SCIENCE COMMUNITY & PUBLIC PARTICIPATION: The science community and the broader public as a whole are encouraged to participate in HiRISE targetting and data analysis. This will be made possible by several key innovations: User-Friendly Image Targeting Interface via HiWEB (based on thesuccessful Marsoweb site, http://marsoweb.nas.nasa.gov/landingsites, currently used for MER landing site selection studies) User-Friendly Image Targeting Interface via HiWEB (based on thesuccessful Marsoweb site, http://marsoweb.nas.nasa.gov/landingsites, currently used for MER landing site selection studies) A web-based clickable, zoomable image data map will allow seamless access to all HiRISE, other MRO, and previous Mars mission data including image, topographic, spectral, and derived data sets. The interface will allow easy Inter-comparison of data sets via transparent overlays on the image data map. A key feature will be rubber-band selection of image targets and a simple justification interface. Similar versions of the interface will be maintained for team members, the science community, and the public at large.

Similar versions of the interface will be maintained for team members, the science community, and the public at large. Anyone may submit suggested image targets, give short justification and list of constraints (season, SNR, resolution, etc.). Science community suggestions will be routed to appropriate HiRISE Co-I for consideration for targeting by spacecraft. Public suggestions will be filtered to minimize duplication and frivolous input. NASA Quest and other partners will host web events and workshops to educate public to encourage high quality suggestions.

Public interest in data analysis demonstrated by 80,000 unique users who collectively identified essentially every impact crater on Mars. Excellent fidelity of results demonstrated by comparison to Barlow crater catalog.
