Compact low power avionics for the Europa Lander concept and other missions to ocean worlds

This paper presents the results of NASA's game changing technology development entitled “Ultra Low Temperature Electronics” which represents a paradigm shift in spacecraft avionics development. The project has developed compact avionics technologies to address the Command & Data Handling (CDH), Power and Motor Control needs for mission concepts to ocean worlds such as a potential Europa Lander. We addressed this need by developing the key technologies necessary to develop a next generation compact avionics package. The key technologies that we developed significantly reduce the size, weight, power, and cost (SWAP-C) of the avionics package. These technologies will also allow extreme-environment missions to last longer in their environment by reducing the power and energy requirement to keep the avionics warm.
