puddingebola writes "I could not track down the original paper, but research now indicates the water on the Moon and Earth share a common origin. From the article, "In investigating primitive lunar samples carried to Earth by the Apollo 15 and 17 missions, the team found a deuterium-to-hydrogen ratio that matched the isotopic ratio in carbonaceous chondrites, which include some of the most primitive meteorites known. The ratio is also similar to that found in water on Earth. The findings “suggest a common source of water for both objects” and provide “a very important new constraint for models of Earth and Moon origin”, says planetary scientist Robin Canup of the Southwest Research Institute in Boulder, Colorado, who was not part of the study." The finding has ramifications for existing theories of formation of the Earth and Moon."
