Abstract

Endurance is a mission concept to explore and ultimately return samples from the Moon's largest and oldest impact basin, South Pole-Aitken (SPA). SPA holds the answers to many outstanding planetary science questions, including the earliest impact bombardment of the Solar System and the evolution of the Moon's interior. Endurance would address these questions by traversing 2,000 kilometers across the lunar farside, collecting samples, and delivering those samples to Artemis astronauts for return to Earth. Endurance was identified as the highest priority strategic mission for NASA's Lunar Discovery and Program in the recent Planetary Science and Astrobiology Decadal Survey. This report summarizes the results from the first public workshop about the concept. Major findings include: (1) Endurance is an exciting concept that would address long-standing, high-priority lunar and planetary science questions, and the community is ready for it. (2) Endurance's sample science objectives are achievable, although they would require coordinated analysis techniques and numerous diverse samples. (3) Geologic context is essential for addressing Endurance's science objectives. (4) While Endurance's objectives center on sample return, Endurance's long traverse would enable a variety of additional transformative science investigations. (5) Endurance is an ambitious mission that would be enabled and enhanced by investing in developing key technologies now. (6) Endurance should strive to include more diverse perspectives in its formulation, particularly from early-career scientists and engineers who will ultimately operate the rover and analyze the samples. Endurance is early in its formulation and the next major activity will be a Science Definition Team (SDT). It is expected that this report and the findings therein may be useful input to the Endurance SDT.
