Chandrayaan-2 DFSAR finds possible subsurface ice near Moon’s south pole

Direct fact

In May 2026, scientists using Chandrayaan-2’s Dual Frequency Synthetic Aperture Radar (DFSAR) payload reported possible subsurface ice near the Moon’s south pole, adding to India’s lunar science data set.

Key specifics

• Chandrayaan-2 is India’s lunar mission, and DFSAR is its Dual Frequency Synthetic Aperture Radar payload.
• The finding concerns the Moon’s south pole, a region of high scientific interest for water-ice studies.
• The report was published in May 2026, making it a current science-and-technology development.
• “Subsurface ice” refers to ice below the lunar surface, a key term in planetary exploration.
• The observation was based on radar data, not on direct surface sampling.
