Terrestrial Analogs for Research and Geologic Exploration Training (TARGET)​

The U. S. Geological Survey (USGS) Astrogeology Science Center (ASC) recently established the Terrestrial Analogs for Research and Geologic Exploration Training (TARGET) program. This service-oriented program is built around the recognition that the Earth is a fundamental training ground for human and robotic planetary exploration, and that ASC is in a unique position in northern Arizona with...

Mars Ice

The Mars-Ice project is a joint project between the USGS Astrogeology Research Program (Flagstaff, AZ) and the Arizona State University Mars Space Flight Facilty (Tempe, AZ) to bring together a single resource for the exploration of martian ices. Much of this research is done at the USGS Flagstaff Science Center.

Mars Dunes

Sand dunes are among the most widespread aeolian features present on Mars, serving as unique indicators of the interaction between the atmosphere and surface. On a planetary body, dunes accumulate where a supply of sand-sized grains exists or may be abraded, is carried downwind by winds of saltation strength, and is subsequently deposited where these winds weaken below the threshold for sand...

MER MI Products

A single MI image or an Microscopic Imager mosaic can be merged with Pancam color images. The two products must be coregistered first, and then added together to produce colorized images in which the intensity comes from the MI and color (hue/saturation) comes from the Pancam images. This method of colorizing data may not yield a satisfactory product if the solar illumination is from a different...

Venus Magellan Impact Crater Database

The NASA Magellan spacecraft provided synthetic aperture radar (SAR) image coverage of 98% of the surface of the planet Venus, in addition to topography and several types of physical property data on the venusian surface (e.g., radar reflectivity, radar backscatter, emissivity, and rms slopes).(See Special Magellan Issue of J. Geophys. Res., v. 97, nos. E8 and E10, August 25 and Sept. 25, 1992.)...

Mars MER Microscopic Imager Surface Findings

The Microscopic Imagers (MI) on the Mars Exploration Rovers , Spirit and Opportunity, have returned images of Mars with higher resolution than any previous camera system, allowing detailed petrographic and sedimentological studies of the rocks and soils. Designed to simulate a geologist’s hand lens, the MI cameras were mounted on the rovers’ instrument arms. They can resolve objects 0.1 mm across...

USGS-NASA Planetary Geologic Mapping Program

The Astrogeology Team at USGS provides coordination of NASA's planetary geologic mapping program. Geologic mapping investigations of any imaged planetary body (except Earth) are proposed to NASA's Planetary Geology and Geophysics Program on an annual basis (generally due sometime between late April and early June) and then reviewed by the Lunar and Planetary Geoscience Review Panel. USGS map...
