Water exists on the moon, scientists confirm


Casey Honniball at Nasa’s ASA Goddard Space Flight Center in Maryland, US, and colleagues have detected a chemical signature that is unambiguously H2O, by measuring the wavelengths of sunlight reflecting off the moon’s surface. The data was gathered by the Stratospheric Observatory for Infrared Astronomy (Sofia), a modified Boeing 747 carrying a 2.7-metre reflecting telescope.

米尔顿·凯恩斯开放大学行星科学和探索教授马赫什·阿南德(Mahesh Anand)说,这些水是在靠近月球南极的高纬度地区发现的,含量约为百万分之一百到四百。它的分量大约与从地球大洋中脊流出的熔岩中溶解出来的水相当,在适当的温度和压力条件下,可以收集这些水分制造液态水。

The water was discovered at high latitudes towards the moon’s south pole in abundances of about 100 to 400 parts per million H2O. “That is quite a lot,” said Mahesh Anand, professor of planetary science and exploration at the Open University in Milton Keynes. “It is about as much as is dissolved in the lava flowing out of the Earth’s mid-ocean ridges, which could be harvested to make liquid water under the right temperature and pressure conditions.”
