Lessons Learned from All-Terrain Hex-Limbed Extra-Terrestrial Explorer Robot Field Test Operations at Moses Lake Sand Dunes, Washington

The Jet Propulsion Laboratory (JPL) is developing the All-Terrain Hex-Limbed Extra-Terrestrial Explorer (ATHLETE) as part of NASA’s Exploration Systems Mission Directorate, Exploration Technology Development Program (ETDP). The program develops technologies for surface mobility and equipment handling, human-system interaction, and lunar surface system repair, and constructs dexterous robots and autonomous rovers that can drive over rough terrain and help crew explore, assemble, and maintain a lunar outpost. ETDP sponsors a series of field tests at lunar analog test sites where prototype robots can operate in ways that simulate lunar surface conditions. In this paper, we describe the lessons learned about ATHLETE operations at the most recent lunar analog field test in June 2008 at Moses Lake Sand Dunes, Washington. The Moses Lake field test was structured as a series of “acts” which correspond to unpiloted and piloted missions to the lunar surface in the 2019 to 2022 timeframe. The field test took place over a period of two weeks and involved several robots from various NASA field centers, including the Chariot lunar truck from Johnson Space Center, the K10 planetary rover from Ames Research Center, and ATHLETE from JPL. Lessons learned from the Moses Lake field test will be incorporated into the evolving design of the ATHLETE operations system, and will be tested at subsequent field trials.
