Lunar Water Discovery: Chinese Scientists Find Mineral Enriched with Water in Moon Soil Samples

Strategic Insights -

Scientists from the Chinese Academy of Sciences have discovered a mineral, dubbed "unknown lunar mineral (ULM-1)," in lunar soil samples returned from the Moon by the Chang'e 5 mission. This mineral is found to be "enriched" with water, revealing the presence of trace water from a much higher latitude than any previous missions. The findings, published in Nature Astronomy, provide evidence of water molecules persisting in sunlit areas of the Moon as hydrated salts. This breakthrough could power future missions to the Moon and contribute to the ongoing space race between the US and China.

Key Takeaways:

  • The Chinese Academy of Sciences discovered a mineral, unknown lunar mineral (ULM-1), enriched with water in lunar soil samples returned from the Moon by the Chang'e 5 mission.
  • The mineral contains over 40% water by mass and has been ruled out as contaminated by rocket exhaust or terrestrial contamination.
  • The discovery suggests that water molecules can persist in sunlit areas of the Moon in the form of hydrated salts.
  • This breakthrough provides fresh clues about the chemical and physical form of Moon water and its implications for mineral extraction for rocket fuel on the lunar surface.
  • In 2020, Nasa announced the discovery of water on the Moon's sunlit surface, following India's Chandrayaan-1 mission detection of hydrated minerals in 2009.
  • The Chang'e-5 lunar lander sent back the first on-site evidence of lunar water, and samples collected continue to shed light on the presence of water on the lunar surface.
  • China plans to send a crewed mission to the Moon by 2030 and aims to build a lunar base, which could utilize the discovered water resources.
  • The discovery has significant implications for the lunar space program, potentially revealing fresh insights into lunar history and evolution.

Statistics:

  • 40% of the mineral sample is comprised of water by mass.
  • The discovery was published in Nature Astronomy.
  • The Chang'e 5 mission returned lunar soil samples from a much higher latitude than previous missions.
  • The US and China are in an ongoing "space race," with Nasa administrator Bill Nelson terming it a new "space race."
