Trent Hare
Trent Hare is a Cartographer at Astrogeology Science Center.
Research Interests
- 2005 to present. Lead for project development and management of cartographic and science research tasks for NASA science and exploration programs (e.g., Planetary Geology & Geophysics, Lunar Mapping & Modeling Project, Applied Information Systems Research, Mars Data Analysis). Includes scientific and cartographic problem definition and analysis, and development of efficient and effective Geographic Information System (GIS) projects for research and analysis of problems in planetary science. Develop and defend reimbursable project budgets to NASA annually and manage personnel to ensure project completion on time and within budget. Develop GIS on-line mapping web sites, tools, and tutorials to facilitate and enable planetary science research and mission support. Compile planetary datasets and publish with ArcMap Server and Open-Geospatial Consortium (OGC) interfaces. Lead technical support for Astrogeology’s Planetary Geologic Mapping coordination program for NASA.
- 2008 to present. Lead and Expert Consultant for development and implementation of a data visualization and analysis tool for space mission operations and scientific research. Created Mars Exploration Rover and Mars Science Laboratory GIS packages which allowed for landing-site analysis and selection. Created the Titan on-line map viewer and Titan Swath Viewer (TSV) in ArcView for the NASA Cassini mission to Saturn. Required research on mission science objectives and redesign of the ArcView user interface to allow a novice GIS user (Cassini science team members) to test different satellite targeting scenarios for mission operations.
- 1994 to present. Developer of analytical software for science and cartographic research. Routinely design and write software in C++, PERL, and Python for photogrammetric and remote sensing software (ISIS) and scientific research using a wide variety of space mission remote-sensing datasets. Frequently serve as expert consultant to research scientists and technical developers on technical research such as design and creation of 3 dimensional image display and analysis and topographic model importers a

The northwestern slope valleys (NSVs) region, Mars: A prime candidate site for the future exploration of Mars
The northwestern slope valleys region is a prime candidate site for future science-driven Mars exploration because it records Noachian to Amazonian Tharsis development in a region that encapsulates (1) a diverse and temporally extensive stratigraphic record, (2) at least three distinct paleohydrologic regimes, (3) gargantuan structurally controlled flood valleys that generally correspond with grav

Geology of the MER 2003 "Elysium" candidate landing site in southeastern Utopia Planitia, Mars
The NASA Mars Exploration Rover (MER) Project has been considering a landing-site ellipse designated EP78B2 in southeastern Utopia Planitia, southwest of Elysium Mons. The site appears to be relatively safe for a MER landing site because of its predicted low wind velocities in mesoscale atmospheric circulation models and its low surface roughness at various scales as indicated by topographic and i

Peleolakes and impact basins in southern Arabia Terra, including Meridiani Planum: Implications for the formation of hematite deposits on Mars
The hematite deposit in Meridiani Planum was selected for a Mars Exploration Rover (MER) landing site because water could be involved in the formation of hematite, and water is a key ingredient in the search for life. Our discovery of a chain of paleolake basins and channels along the southern margin of the hematite deposits in Meridiani Planum with the presence of the strongest hematite signature

Possible Juventae Chasma subice volcanic eruptions and Maja Valles ice outburst floods on Mars: Implications of Mars Global surveyor crater densities, geomorphology, and topography
This article discusses image, topographic, and spectral data from the Mars Global Surveyor (MGS) mission that provide new information concerning the surface age, geomorphology, and topography of the Juventae Chasma/Maja Valles system. Our study utilizes data from two instruments on board MGS: images from the Mars Orbiter Camera (MOC) and topography from the Mars Orbiter Laser Altimeter (MOLA). Wit

High-resolution topomapping of candidate MER landing sites with Mars Orbiter Camera narrow-angle images
We analyzed narrow‐angle Mars Orbiter Camera (MOC‐NA) images to produce high‐resolution digital elevation models (DEMs) in order to provide topographic and slope information needed to assess the safety of candidate landing sites for the Mars Exploration Rovers (MER) and to assess the accuracy of our results by a variety of tests. The mapping techniques developed also support geoscientific studies

Resurfacing history of the northern plains of Mars based on geologic mapping of Mars Global Surveyor data
Geologic mapping of the northern plains of Mars, based on Mars Orbiter Laser Altimeter topography and Viking and Mars Orbiter Camera images, reveals new insights into geologic processes and events in this region during the Hesperian and Amazonian Periods. We propose four successive stages of lowland resurfacing likely related to the activity of near-surface volatiles commencing at the highland-low

Catastrophic erosion of Hellas basin rim on Mars induced by magmatic intrusion into volatile-rich rocks
Malea and Hesperia Plana form large sectors of the rim of Hellas basin that display partly eroded volcanic shields and plains. These regions have topographic profiles that appear to be several hundred meters lower than those of adjacent rim sectors and lack prominent massifs of remnant basement that would be expected to stand above the lava plains. We interpret that before the volcanic edifices we

Validation of the USGS sensor model for topographic mapping of Venus using Magellan radar stereoimagery
The Magellan spacecraft went into Venus orbit in 1990 and by 1992 had made three complete cycles of polar orbits, each cycle covering the full range of longitudes. During this time the spacecraft obtained synthetic aperture radar (SAR) images of >96% of the planet at a resolution of 75 m/pixel. Images taken with a decreased look angle from vertical, primarily during Cycle 3, provide stereo coverag
