NASA Develops Passive Thermal Control System for Small Lunar Rovers

NASA is developing a new thermal management technology called ECLIPSE, designed to regulate temperatures in small, mobile lunar systems. Unlike existing solutions built for large infrastructure, ECLIPSE targets compact, independent devices that must operate without heaters or significant power supplies. The system aims to limit damaging temperature fluctuations that can stress hardware during lunar missions. It was developed in response to growing demand for disaggregated lunar infrastructure, where smaller units function autonomously. The innovation could be key to enabling reliable, low-power operations across future lunar exploration efforts.
