Executive Summary
Chronologic investigations of newly identified samples from the Apollo lunar sample collection will be completed in order to constrain the age, origin, and evolution of the Moon. This research supports National Aeronautic and Space Administration missions as it will position Lawrence Livermore National Laboratory to conduct forensic analyses of returned samples from Moon missions.
