Water on Moon Questioned.
Scientist has discovered that the amount of water present on the moon’s surface may have been overestimated by scientist studying lunar rock* samples. To know more read the full Article.
Using data collected by India’s Chandrayaan mission, NASA has detected magmatic water locked under the surface of the Moon.
The findings represent the first remote detection of this form of water that originates from deep within the Moon’s interior, NASA researchers said. Earlier studies had shown the existence of magmatic water in lunar samples returned during the Apollo programme.
NASA said scientists using data from the Moon Mineralogy Mapper (M3) instrument aboard the Indian Space Research Organisation’s Chandrayaan-1 spacecraft, remotely detected magmatic water, or water that originates from deep within the Moon’s interior, on the lunar surface.
Lunar water is water that is present on the Moon. Liquid water cannot persist at the Moon’s surface, and water vapor is decomposed by sunlight, with hydrogen quickly lost to outer space. Inconclusive evidence of free water ice at the lunar poles was accumulated from a variety of observations suggesting the presence of bound hydrogen. On 18 November 2008, the Moon Impact probe was released from India’s Chandrayaan-1 at a height of 100 kilometres (62 mi).
That is contrary to 40 years long held dry moon assumption. The discovery of hydrogen rich apatite* with lunar rocks in 2010 seemed to hint at a more watery past.
The new study revealed that the unusually hydrogen-rich apatite crystals observed in many lunar rocks samples may not have formed within a water-rich environments was originally expected.
The mineral apatite is the most widely used method for estimating the amount of water in lunar rocks. The detection of internal water from orbit means scientists can begin to test some of the findings from sample studies in a broader context, including in regions that are far from where the Apollo sites are clustered on the near side of the Moon.
