All wet, or high and dry?

The lunar interior may contain far less water than Earth’s

The inside of the moon might not be all wet after all. A new study suggests that, contrary to recent work, the lunar interior is as bone-dry as scientists thought 40 years ago, when NASA astronauts lugged home the first moon rocks.

New analyses of chlorine in those rocks, published online August 5 in Science, indicate that the moon contains just one-10,000th to one-100,000th the water that the Earth’s interior does.
