We know that the moon was likely created out of material from our planet because we share the same isotopes, making us the solar system equivalent of fraternal twins. When the astronauts of Apollo 11 took off from Earth 50 years ago today, they were visiting a long-lost relative.

In the images sent back by Apollo 11, the moon looked like an airless wasteland. But like the Earth, the moon also has water, as well as hydrated minerals called hydroxyl. This abundance of hydrogen could have been delivered in a myriad of ways. During the formation of the Earth and the Moon, a water delivery system was created from comets and asteroids impacting the surface, and from the interaction of sunlight with hydrogen molecules on the lunar surface.

While scientists know that the Moon is covered with a variety of hydrogen, they are unclear about exactly how much water is on the Moon, or even where it is located. Missions that have orbited the Moon have done basic…
