Scientists in NASA have discovered water molecules in the polar regions of the Moon. It has been said that more water has been found than was predicted by scientists. The analysis of the data by the Moon Mineralogy Mapper (M3) on board Chandrayaan-I has led to the find. The result was published in the journal, Science. Here is the video of Press Meet compiled by the society exclusively in order to share the historic announcement of Water Ice on Moon . Other parts of the Video would be uploaded in a day. What is the Moon Mineralogy Mapper? The M3 scientific instrument is a high throughput pushbroom imaging spectrometer, operating in 0.7 to 3.0 µm range. It measures solar reflected energy, using a two-dimensional Hg-Cd-Te detector array. A spectrometer is a device which is used to measure properties of light which helps to identify materials. It is a payload on board Chandrayaan-I from Brown University and Jet Propulsion Laboratory through NASA, USA. What is the role of Chandrayaan-I in this finding? Chandrayaan-I is India's first mission to the Moon. Chandrayaan-I carried the Moon Mineralogy Mapper (M3) which is the instrument that found nearly 700 parts per million of water molecules on the Moon. M3 is an instrument provided by NASA. It was results from M3 which led scientists to re-check the information found by Cassini, Deep Impact and the samples from the Moon returned during the Apollo missions. The results were analysed jointly by Indian and American scientists jointly led by Dr. Carla Pieters of Brown University while the Indian team led by Prof. J. N. Goswami of Physical Research Laboratory, India. When did Cassini and Deep Impact look at the Moon? Deep Impact (now called Epoxi) had studied the Moon during June 2 and June 9 2009. Cassini is a spacecraft that is now studying Saturn and her Moons. Cassini studied the Moon on its way to Saturn in 2005. Both these data confirmed the finding that M3 had proposed.
