Magmatic volatiles (H, Cl, F, S, C, N) are a powerful tool for understanding how planetary bodies formed and evolved. Recent advancements in analytical instrumentation have permitted discoveries of volatiles in lunar samples that were not possible during the Apollo era. In this talk I will present hydrogen and chlorine isotope data obtained from a geochemically diverse group of lunar rocks. These data provide evidence for the common heritage of water in the Moon, Earth, Mars, and some ancient asteroids, and allow us to explore the roles that volatiles played during the magmatic differentiation of the Moon and subsequent mare volcanism.
