RESTON, VA. — The U.S. Geological Survey used cutting-edge Earth science to publish the first off-planet mineral prospectivity map – assessing likely places to find lunar ice near the Lunar South Pole for a NASA mission.
“The USGS and NASA have partnered for over 50 years to leverage space technologies to map the Earth’s resources, and to bring Earth science to bear on space exploration,” said Sarah Ryker, acting USGS director.“As the nation plans to return astronauts to the Moon, the Artemis missions will require resources prohibitive to bring from Earth. Our USGS expertise in assessing resources will help locate ice, which can be purified for drinking, or electrolyzed to make hydrogen and oxygen, key ingredients in rocket fuel.”
Since its establishment in 1879, the U.S. Geological Survey has been mapping mineral resources in the U.S. and on Earth, with satellite-based scanning beginning in 1972. Off-planet prospectivity is the latest step in the USGS and NASA’s partnership applying Earth science tools to space.
NASA’s planned VIPER, or Volatiles Investigating Polar Exploration Rover, mission will explore volatile-bearing deposits within the loose surface materials near the Moon’s South Pole, specifically around the Mons Mouton landing site. By locating and characterizing these resources, particularly water ice, the mission could reduce the need to transport such materials from Earth, supporting long-term lunar exploration and future space missions.
“Contributing to the VIPER Science Team helps the USGS test our methods in new settings, with new types of data. This mission represents a bold leap forward in lunar science, and also advances what we do on Earth,” said Joshua Coyan, lead author of the study and a research geologist with the USGS Mineral Resources Program.
Mapping lunar resources paves the way for uncovering critical supplies on other planetary bodies. On Earth, the USGS maps energy and water resources; on the Moon and other planets, as on Earth, water is a potential energy resource.
To support the VIPER mission, the USGS Mineral Resources Program partnered with NASA, the University of Hawai’i, and the Search for Extra-Terrestrial Intelligence (SETI) Institute to develop a new astrogeological prospectivity map with the goal of identifying locations with a high likelihood of containing water-ice deposits around the Lunar South Pole.
“This is the first time Earth-based geostatistical techniques have been adapted to map potential resources on another celestial body,” said Coyan. “By applying proven terrestrial methods in a new planetary context, we’re showing that the tools used to assess mineral potential on Earth can also help identify strategic exploration targets on the Moon and potentially beyond.”
Studying these potential water ice deposits may also help to shed light onto the origin and distribution of these lunar volatiles, offering a deeper understanding of the Moon’s geologic and thermal evolution.
The team found that there are several highly prospective areas near the VIPER landing site. Notable locations include the bases of the Jaci, Masina, and Dawa craters, in addition to several smaller clusters of depressions in the surrounding areas.
The prospectivity map was generated using methodologies for uncovering drilling and mining locations. Remote sensing and geophysical data on the lunar poles are relatively scarce, so the team used a “fuzzy logic” artificial intelligence technique to locate areas with high potential for ice based on factors like shade and slope.
These techniques were designed to improve as new data is collected during the mission, allowing for near-real time refinement of the locations considered prospective for water ice. back...
