For many years, researchers believed that the rocks from the Moon were 'bone dry' and that any water detected in the Apollo samples had to be contamination from Earth. But about five years ago, new laboratory techniques revealed that the interior of the Moon is not as dry as previously thought. Around the same time, data from orbital spacecraft detected water on the Lunar surface, which is thought to be a thin layer formed from Solar wind hitting the Lunar surface. After examining new data it was found that the crater has significantly more hydroxyl — a molecule consisting of one oxygen atom and one hydrogen atom — compared to its surroundings. The internal magmatic water provides information about the Moon's volcanic processes and internal composition. The research confirms earlier lab analyses of Apollo samples.
Visionary researchers here on Earth are already designing our future Lunar bases.
