+*Title:* Autonomous Task and Motion Planning for Ice Worlds Exploration
+
+*Abstract:* Icy moons of the gas giant planets, such as Europa, Titan, and Enceladus, are at the forefront of astrobiological interest due to the evidence of subsurface oceans. Enceladus is unique among the icy moons because there are known vent systems that are likely connected to a subsurface ocean, through which the ocean water is ejected to space. An existing study has shown that sending small robots into the vents and directly sampling the ocean water is likely possible. To enable such a mission, JPL is developing a novel, snake-like robot called Exobiology Extant Life Surveyor (EELS) that can navigate Enceladus' extreme surface and descend an erupting vent to capture unaltered liquid samples and potentially reach the ocean. However, navigating to and through Enceladus' environment is challenging: there is substantial uncertainty with respect to its geometry and physical properties of the surface/vents due to the limitations of existing orbital reconnaissance; and communication is limited which requires highly autonomous robots to execute the mission with limited human supervision. In this talk we provide an overview of the EELS project and its development effort to create a risk-aware autonomous robot to navigate these extreme ice terrains/environments. We describe the robotÕs architecture and the technical challenges to navigate and sense the icy environment safely and effectively. We focus on the challenges related to surface mobility, and task and motion planning under uncertainty. We provide initial results on mobility and risk-aware task and motion planning from field tests and simulated scenarios.
