Ancient Moon Samples
In July 2008, water was found conclusively for the first time inside ancient moon samples brought back by Apollo astronauts. Researchers led by Brown geologist Alberto Saal analyzed lunar volcanic glasses, such these gathered by the Apollo 15 mission, and used a new analytic technique to detect water. The discovery strongly suggests that water has been a part of the Moon since its early existence – and perhaps since it was first created.
