MOON WATER All of you might have heard about presence of water on moon. Have you ever wondered why Moon has water on it.Does really Moon has water?

Do you know how EARTH has water on it there is a theory behind it;either by water itself or its components of hydrogen and oxygen,was deposited on earth's surface during a period of "late heavy bombardment" around 3.9 billion years ago-by the impact of comets and asteroids.

Since Moon shares the same area of space as Earth it might have received its share of water as well. However moon has only tiny fraction of earths gravity most of its water supply should have evaporated or drifted away in space long ago. Most perhaps not all.Here is the image of water bearing comets and asteroids. In 1960s Apollo flights confirmed that the dominant geological process on Moon is impact related. This conformation in turn ushered new question:Since Earth's water was delivered largely by comets and asteroids,could this process have done the same for Moon.

In 1998 NASA had sent another space craft LUNAR PROSPECTOR to scan Moon's surface for water using neutron spectrometer. Once again polar craters yielded a intriguing signal:neutron ratios indicated hydrogen.

If presence of water on Moon is for sure then in future men will be living on it. And it will be good for human kind.
