Scientists from India's Physical Research Laboratory and the Indian Space Research Organisation have detected possible subsurface ice at the Moon's south pole [1].
The discovery is significant because these ice deposits could provide essential water, oxygen, and rocket fuel for future human missions to the lunar surface [1].
Researchers analyzed data from the Dual Frequency Synthetic Aperture Radar, an instrument aboard the Chandrayaan-2 spacecraft [2]. The team identified signals consistent with the presence of ice located beneath the surface in permanently shadowed craters [2]. These regions are of particular interest to space agencies because they never receive direct sunlight, allowing volatile materials to remain stable over billions of years [4].
The research, which was conducted in 2024 [1], focuses on the specific geological characteristics of the south pole region [3]. By using the radar's ability to penetrate the lunar crust, the scientists were able to look beyond the surface layer to find these potential reserves [4].
While the findings are described as possible deposits, the data provides a new map of where resources may be concentrated [2]. This information helps refine the landing sites for future missions that aim to extract lunar volatiles for sustainable habitation [1].
This effort represents a collaborative analysis between the Physical Research Laboratory and the Indian Space Research Organisation to maximize the scientific output of the Chandrayaan-2 mission [1]. The use of the DFSAR instrument allows for a more detailed understanding of the lunar subsurface than previous optical observations alone [2].
“Possible subsurface ice deposits beneath the Moon’s south-pole region”
The identification of subsurface ice transforms the lunar south pole from a scientific curiosity into a strategic resource hub. If confirmed, these reserves reduce the mass of supplies humans must carry from Earth, enabling longer-term lunar bases and serving as a refueling station for deeper space exploration.
