ISRO Discovers Evidence of Ice in the Moon's Polar Regions
Increased Evidence of Subsurface Water Ice
A recent study by the Indian Space Research Organisation (ISRO) has revealed compelling evidence of water ice in the Moon's polar craters. This study suggests that the amount of subsurface ice in the first few meters is approximately 5 to 8 times greater than the amount of ice on the surface at both the northern and southern poles. The discovery has significant implications for future lunar exploration and potential long-term human habitation.

Collaboration and Research Findings
The study was conducted by scientists from ISRO's Space Applications Center (SAC), in collaboration with researchers from IIT Kanpur, University of Southern California, Jet Propulsion Laboratory, and IIT (ISM) Dhanbad. The findings indicate that the northern polar region has twice as much water ice as the southern polar region.
This discovery underscores the importance of drilling on the Moon to sample or excavate ice for future missions and long-term human presence. The origin of this ice, as confirmed by the study, is attributed to volcanic outgassing during the Imbrian period. The study also concludes that the distribution of water ice is likely controlled by Mare Volcanism.
Methodology and Significance of Findings
To understand the origin and distribution of water ice on the Moon, the research team used seven instruments on the Lunar Reconnaissance Orbiter, including radar, laser, optical, neutron spectrometer, ultraviolet spectrometer, and thermal radiometer. These instruments provided valuable data to map and analyze the presence of water ice in the Moon's polar regions.
Accurate knowledge of the distribution and depth of water ice is crucial for planning future missions and selecting landing and sampling sites. This knowledge helps reduce uncertainties and enhances the efficiency of missions focused on exploring and characterizing lunar volatile substances.
Supporting ISRO's Previous Study and Future Missions
The new findings support ISRO's previous study using polarimetric radar data from the Chandrayaan-2 dual-frequency synthetic aperture radar instrument, which indicated the presence of water ice in some polar craters. These studies collectively point to the potential of water ice as a valuable resource for future lunar exploration.
The evidence of water ice in the Moon's polar regions provides significant opportunities for space agencies to explore the potential of lunar resources. The information derived from these studies can guide future missions, facilitating sustainable lunar exploration and paving the way for long-term human habitation on the Moon.
Conclusion
ISRO's discovery of evidence of ice in the Moon's polar regions represents a significant breakthrough in lunar exploration. The findings provide a deeper understanding of the origin and distribution of water ice on the Moon, offering valuable insights for future missions and the potential for long-term human presence. As space agencies continue to explore the Moon, these studies play a crucial role in guiding mission planning and resource utilization.
