You've likely heard by now the news of the discovery of water on the moon. From Science,
"All told, LCROSS detected about 100 kilograms of water, Colaprete said.
It came from a 20-meter-wide crater maybe 3 meters deep, but he
declined to guess how abundant water ice had been beneath the impact
site. Team members must still calculate what portion of subsurface ice
actually rose into view and could have been measured, Colaprete noted.
"It would probably be safe to say it's wetter than the Atacama Desert,"
the driest place on Earth, he said."
A nice marker for a crucial time in history. Really, after the Copernican revolution, who dared think that the moon also had its secrets?
