Water ice Found in Polar Craters of the Moon

By /

In News

  • ISRO study has revealed evidence for enhanced possibility of water ice occurrence in the polar craters of the Moon.

 Key Findings of the Study

  • Source of Ice: The primary source of sub-surface water ice in the lunar poles is outgassing during volcanism in the Imbrian period.
  • Presence of Water Ice: There is twice as much water ice in the northern polar region compared to the southern polar region.

Significance

  • This study is crucial for supporting ISRO’s future in-situ volatile exploration plans on the Moon and longterm human presence.
  • The findings of this study also supports the earlier study of Chandrayaan-2 related to presence of water on the moon.
Related Facts on the Moon

–       The Moon is the only natural satellite orbiting Earth.

–       The Moon has a diameter of approximately 3,474 kilometers, which is about one-quarter the size of Earth.

–       The Moon’s gravity is about one-sixth of Earth’s gravity. However, it plays a significant role in creating tides on Earth due to the differential gravitational pull on different parts of the planet.

–       The Moon exhibits different phases throughout the month due to its relative positions with Earth and the Sun.

–       India has undertaken three lunar missions, Chandrayaan-1 (2008), Chandrayaan-2 (2019) &.Chandrayaan-3 (2023). These missions have contributed to our understanding of the Moon’s composition, mineralogy, potential resources & soft landing on the moon’s South pole.
