Science Priorities for Sample Return for Artemis Missions to the Lunar South Pole

Abstract

Samples are needed to address scientific as well as engineering knowledge gaps. Samples collected during the Apollo missions have been studied for five decades and continue to be investigated vigorously. Because of the lasting importance of the samples and to ensure that samples returned to Earth maintain their integrity, curation of the samples is also a crucial activity. In this white paper, we address the key science priorities for which samples are needed.
