Water More Abundant Than Previously Believed
06.15.10
 
NASA-funded scientists estimate that the volume of water molecules locked in minerals in the moon’s interior could exceed the volume of water in the Great Lakes here on Earth. Scientists at the Carnegie Institution’s Geophysical Laboratory, along with scientists across the nation, determined that the water was likely present very early in the moon’s formation history as the hot magma started to cool and crystallize. The result means water is native to the moon; it’s found in its structural form, hydroxyl, a very minor component of the rocks that make up the lunar interior.

Cut 1 (00:20) - “What’s really exciting about these observations is that it is allowing us for the first time  to understand what the conditions of the early Earth was when the Earth and the moon were formed together from a collision of a Mars sized object  that hit the Earth 4.5 billion years ago.”

Cut 2 (00:15) - “So the measurements they are making now, finding these very small, incredibly tiny amounts of hydroxyl,  tell us a lot about the amount of water at the early formation stage of the Earth and the moon.”

Cut 3 (00:15) - “Well this is not really H2O, water that we know, so it’s not like its pools of water or even ponds of water, it’s actually ancient water that has been modified in the solidification process of the moon during the time of its early formation. “
