As NASA prepares to return to the Moon, learning from history is important for ensuring that a sustainable and long-term lunar return is possible. The Apollo program was not sustainable. The purpose of this workshop is to bring together academic, governmental, and private sector interests to focus on the sustainability theme of the LEAG-coordinated Lunar Exploration Roadmap. The meeting will incorporate the results from the latest missions (especially the LRO/LCROSS mission) to ensure that the framework for a sustainable presence is established early in this next era of lunar exploration.
