Exploration of Mars is currently underway by use of a rover and helicopter team. A hybrid ground/aerial vehicle concept that marries the respective strengths of rovers and rotorcraft for Mars exploration is presented in this paper. LILI (Long-term Ice-field Levitating Investigator) is a novel hybrid ground- and aerial-mobility concept vehicle proposed for exploration of the Martian polar regions. LILI combines episodic rotary-wing flight with primary ground-mobility-mode of a propeller-driven sled via an arrangement of three skis/runners and tilting proprotors. In this manner, the best of both worlds can be achieved for Mars polar exploration: rapid, obstacle-bypassing flight with low-power, efficient, longer duration -- and range -- sledding. LILI’s propulsion system is based on solar-electric recharging of batteries. Consequently, periods of its air or ground movement are separated by periods of recharging. The overall project goal is to refine the vehicle and mission concept, while constrained within the current technology state of the art, and, leveraging the design heritage of the Ingenuity Mars Helicopter technology demonstrator. LILI’s aerodynamic performance, flow interactions, and design characteristics, as well as potential mission profiles are suggested.
