Robotic and Human-Assisted Lunar Sample Return

A study of the feasibility of a robotic lunar sample return mission has been performed that leverages NASA’s currently planned exploration missions. The primary mission objective is to return a one kilogram sample of lunar farside regolith to Earth-Moon L2 (EM L2). In order to address the primary objective, elements have been designed to achieve orbit, descend to the South Pole/Aitken Basin (SPA), collect a sample, and return it to E-M L2. After delivery to a holding orbit, the ascent module and sample canister wait for collection by a human mission for Earth return and further study. After liftoff of the ascent module, the rover continues operations at the SPA to address multiple Strategic Knowledge Gaps regarding exploration objectives. To meet the mission objectives, a design selection process for each element is conducted and an overall mass and volume estimate of the elements is provided.
