Indian Scientists Discover Evidence of Water Ice in Moon's Polar Craters

  • 07 May 2024

Recently, Indian space scientists, in collaboration with international researchers, have uncovered compelling evidence indicating an increased likelihood of water ice occurrence in the polar craters of the Moon.

Key Points

  • Sub-Surface Ice: The research reveals that the amount of sub-surface ice in lunar polar craters is significantly higher (five to eight times) than surface ice, emphasizing the importance of drilling for future missions and human presence on the Moon.
  • Polar Disparity: The study indicates that the northern polar region of the Moon has twice the extent of water ice compared to the southern polar region.
  • Origin of Ice: The findings confirm the hypothesis that sub-surface water ice in lunar poles originates from out-gassing during volcanism in the Imbrian period.
  • Methodology: Seven instruments, including radar, laser, optical, neutron spectrometer, ultra-violet spectrometer, and thermal radiometer, aboard the NASA Lunar Reconnaissance Orbiter, were utilized for the research.
  • Mission Implications: Accurate knowledge of water ice distribution and depth is crucial for selecting future landing and sampling sites for lunar exploration missions.
