Lunar Exploration Objectives
Almost 200 lunar exploration objectives resulted from the Global Exploration Strategy process. NASA engaged the global space community to develop the objectives by asking the question, "What do we hope to accomplish through lunar exploration?"
NASA took the many answers to this question and compiled them into a comprehensive database of almost 200 different things we could do on the moon! The lunar exploration objectives are meant to capture the entire set of activities that anyone involved in lunar exploration may want to pursue. These activities could be carried out by NASA, another space agency, a private company, a university, or anyone else who invests in space exploration
