Chandrayaan-3 Data Suggests Water Ice Easier to Find on Moon, PgII

Major Findings from Chandrayaan-3

• Vikram Lander’s instrument recorded surface temperature at its location as 82°C, while just a metre away, it dropped to 58°C.
• Significant temperature variations indicate the possibility of water ice stabilizing beneath the surface.
• Researchers at the Physical Research Laboratory (PRL), Ahmedabad, found that water-rich areas on the moon are more common than expected.

Significance of Discovery

• Moon water can support astronauts’ drinking and sanitation needs.
• Can be used as fuel for space missions.
• Supports long-term human exploration & moon habitation projects.

First In-Situ Measurement of Moon’s Surface Temperature

• ChaSTE (Chandra’s Surface Thermophysical Experiment) measured lunar soil temperatures.
• Temperature gradient showed significant variations between shaded and sunlit areas.
• Shiv Shakti Point, where Vikram landed, recorded higher-than-expected temperatures.

Analysis & Way Forward

• Findings pave the way for future lunar resource extraction projects.
• Encourages further exploration of high-latitude regions, which are less challenging than permanently shadowed areas.
• Global lunar exploration missions (NASA’s Artemis, China’s Chang’e) may leverage these insights for sustainable moon colonization.

Mains Mock Question:

Discuss the significance of Chandrayaan-3’s findings on lunar water ice and their implications for future space exploration and human habitation on the Moon.
