The Astrogeology Science Center serves the nation, the international science community, and the general public in the pursuit of new knowledge about our Solar System. The program has participated in analyzing data from numerous missions to planetary bodies, mapping planets, moons, and asteroids, and researching these body’s geologic processes.
Our scientists work with NASA and other space agencies to lead investigations, select rover landing sites, create geologic maps and cartographic products for numerous spacecraft missions throughout our solar system. Our Astrogeology Science Center continues to provide support for numerous past, present and future space missions.
The USGS Astrogeology Science Center is a hub for planetary research. The center provides guest facilities, labs, and numerous cartographic resources for both the scientific community and the general public. Geologists, archivists, data specialists, and cartographers are employed at the center to assist the planetary science community.
The Astrogeology Science Center's mission includes producing planetary maps and cartographic products which reveal topography, geology, topology, image mosaics and more, all made available to the international scientific community and the general public as a national resource.
We study geology, volcanism, astrobiology, dunes, ice and water flow, crater aging, mineral deposits and the make-up of various planetary surfaces. Our research leads to a better understanding of the character of our neighboring planets, the origins of the solar system, and a better comprehension of our own planet, Earth.
ISIS has many standard image processing operations such as contrast stretch, image algebra, filters, and statistical analysis. Isis operates on both classical two-dimensional images as well as three-dimensional cubes collected from imaging spectrometers. It also has unique capabilities for processing data from NASA spacecraft missions.
PILOT is a web based search tool for the Unified Planetary Coordinate (UPC) database of the Planetary Data System. PILOT features SPICE-corrected image locations and searching capabilities using a navigable map, user selectable image constraints, and facilitates bulk downloads and/or image processing using POW.
The Map Projection on the Web service was created to help researchers convert raw Planetary Data System images to a science-ready map projected images. The system integrates the Planetary Image LOcator Tool (PILOT) and the Unified Planetary Coordinate (UPC), ISIS3, GDAL, and the Astrogeology processing cluster for its’ processing needs.
Astro Web Maps – Our Web Mapping Services (WMS) and Web Feature Services (WFS) are based on Open Geospatial Consortium standards and allow capable mapping clients to view full-resolution planetary mosaicked Basemaps. Services are available for community use and are critical for our Planetary Nomenclature, Planetary Geologic Mapping and PILOT sites
Allows existing map-projected (derived) image products to be re-projected, stretched, clipped, and converted into a variety of useful formats. Version 2 allows us to quickly add new mosaics and potentially many other derived science products for conversion and download.
GDAL is a translator library for raster geospatial data formats that is released under an X/MIT style Open Source license by the Open Source Geospatial Foundation. As a library, it presents a single abstract data model for all supported formats. It also comes with a variety of useful commandline utilities for data translation and processing.
The Planetary Geologic Mapping Program serves the international science community through the production of high-quality and refereed geologic maps of planetary bodies. This program is in coordination between NASA science programs and the USGS Astrogeology Science Center.

Flyover of the southeast Ceti Mensa map. Distinct groups of rock layers, called geologic units, are shaded in different colors, with dark browns representing the oldest rocks and green representing the youngest rocks. All of these rocks formed as wind-blown sand that became trapped in shallow, ephemeral lakes, similar to the wet playas of the desert southwest US. The irregularly-shaped green unit is a large landslide that brought rocks from higher up on Ceti Mensa down into this area.
A new set of high-resolution geologic maps reveal complex geologic processes that suggest a dynamic, wet environment once existed on early Mars, according to the USGS.

This global geologic map of Mars, which records the distribution of geologic units and landforms on the planet's surface through time, is based on unprecedented variety, quality, and quantity of remotely sensed data acquired since the Viking Orbiters. These data have provided morphologic, topographic, spectral, thermophysical, radar sounding, and other observations for integration, analysis, and interpretation in support of geologic mapping. In particular, the precise topographic mapping now available has enabled consistent morphologic portrayal of the surface for global mapping (whereas previously used visual-range image bases were less effective, because they combined morphologic and albedo information and, locally, atmospheric haze). Also, thermal infrared image bases used for this map tended to be less affected by atmospheric haze and thus are reliable for analysis of surface morphology and texture at even higher resolution than the topographic products.
Dark features previously proposed as evidence for significant liquid water flowing on Mars have now been identified as granular flows, where sand and dust move rather than liquid water, according to a new article published in Nature Geoscience by the U.S. Geological Survey.
Billions of dollars and a decade worth of research are on the line in the instant that a spacecraft touches down on Mars. When deciding where to land on the planet’s rocky surface, it is essential to analyze potential landing sites and their surface characteristics.
A new set of high-resolution geologic maps reveal complex geologic processes that suggest a dynamic, wet environment once existed on early Mars, according to the U.S. Geological Survey.
Scientists have discovered possible evidence for water-rich minerals on the surface of the largest metallic asteroid in the solar system, according to a study by the U.S. Geological Survey and NASA.
A new global geologic map of Mars –the most thorough representation of the "Red Planet's" surface – has been published by the U.S. Geological Survey. This map provides a framework for continued scientific investigation of Mars as the long-range target for human space exploration.
Mountains on Io, Jupiter’s volcanic moon, are formed by a unique geologic mechanism not found elsewhere in the solar system, according to a new study by the U.S. Geological Survey.
The first topographic map of Mercury was released today by the U.S. Geological Survey, Arizona State University, Carnegie Institute of Washington, Johns Hopkins University Applied Physics Laboratory and NASA.
