NASA TechPort describes this completed Astrobotic SBIR/STTR project as an integrated lunar CubeRover technology effort combining an ultra-compact radioisotope heater for lunar-night survival, a long-range software-defined rover-to-orbital radio, commercial mobility-as-a-service, and lunar in-situ mobility testing. The technologies were to be integrated and demonstrated on a polar lander mission, advancing a multi-day, long-range rover architecture for lunar exploration and commercial operations.
