New Delhi: Scientists from the Indian Space Research Organisation (ISRO) have discovered possible subsurface water-ice deposits beneath permanently shadowed craters near the Moon’s south pole.
The discovery was made using radar data collected by the Chandrayaan-2 lunar orbiter. This new finding could become a major breakthrough for future Moon missions and long-term human settlement plans.
Details of ISRO Moon Water-Ice Discovery
According to official findings shared by ISRO-backed researchers:
- Scientists studied four permanently shadowed craters near the lunar south pole.
- Radar signals showed possible signs of buried water-ice beneath the surface.
- The strongest evidence came from the Faustini crater region.
- The suspected ice deposits are hidden in areas that never receive sunlight.

These extremely cold regions can preserve ice for billions of years because temperatures remain around 25 Kelvin, or nearly minus 248 degrees Celsius.
ISRO Moon Water-Ice Discovery: How Chandrayaan-2 Detect
The Chandrayaan-2 orbiter carries a special radar instrument called:
- Dual Frequency Synthetic Aperture Radar (DFSAR)
This radar can scan below the Moon’s surface and identify hidden structures or materials. Scientists used this technology to study underground features near the Moon’s south pole.
Researchers noticed unusual radar reflections and crater shapes that strongly suggest the presence of underground water-ice.
Why ISRO Moon Water-Ice Discovery Is Important
This discovery is very important for future lunar missions because water is one of the most valuable resources in space.
Possible uses of lunar water-ice include:
- Drinking water for astronauts
- Producing oxygen
- Creating rocket fuel
- Supporting long-term Moon bases
- Reducing the cost of deep-space missions
Many future missions, including NASA’s Artemis program and India’s future Moon exploration plans, are focused on the Moon’s south pole because scientists believe it may contain frozen water reserves.
ISRO’s Growing Role in Space Exploration
India’s space agency continues to gain global attention after the success of Chandrayaan missions.
Major achievements include:
- Discovery of water signatures during earlier Moon missions
- Successful Chandrayaan-3 south pole landing
- Advanced lunar mapping through Chandrayaan-2 orbiter
- Long-term lunar surface and underground studies
The Chandrayaan-2 orbiter is still operational and continues to send valuable scientific data from lunar orbit.
What Scientists Say
Scientists believe the newly identified regions may contain stable underground ice deposits protected from sunlight and radiation.
Researchers also say these permanently shadowed regions are among the coldest places in the solar system, making them ideal for preserving frozen water over very long periods.
Global Interest in Moon’s South Pole Rising
The Moon’s south pole has become one of the most important targets in modern space exploration.
Countries and space agencies are now competing to:
- Study lunar ice reserves
- Build Moon research stations
- Prepare for Mars missions
- Develop future space mining technologies
India’s latest findings strengthen its position as a major player in global lunar research.
