Water on Moon

Scientists first touch the moon and brought pieces of it back to Earth, scientists have thought that the lunar surface was bone dry. But new observations from three different spacecrafts have put this notion to rest with what has been called "unambiguous evidence" of water across the surface of the moon. The moon remains drier than any desert on Earth, but the water is said to exist on the moon in very small quantities. One ton of the top layer of the lunar surface would hold about just 32 ounces of water, the scientist saying. We remember that when Apollo astronauts returned from the moon 40 years ago, they brought back several samples of lunar rocks. The moon rocks were analyzed for signs of water bound to minerals present in the rocks, while trace amount of water were detected ,these were assumed to be contamination from Earth, because the containers the rock came back in had leaked.

The isotopes of oxygen that exist on the moon are same as that exist on Earth, so it was difficult if not impossible to tell the difference between water from moon and water from earth" said Larry Taylor of the university of Tennessee,Knoxville, who is a member of one of the NASA -built instrument teams for India's Chandrayaan-1 satellite and has studied the moon since the Apollo mission. Now we can have doubt about this discovery. Cause moon is not far away from the earth and why it took so long time to find out water on moon. And if now scientists are saying that there is water. Then how to believe that? And the water which was not found to any other satellite was wonderfully found by Chandrayaan. For that expedition India spent more then 800 drone rupees. And where is that satellite now?!?
