The NETLANDER mission, planned for 2007, will be the first mission to establish an operating network of stations on the surface of Mars. Each one of the four identical landers is equipped with science payloads dedicated to study the atmosphere and geosphere of Mars; operating together or stand-alone they will investigate Martian meteorology, ionosphere, ground and subsurface. Landing locations spread over two hemispheres and a mission duration of one Martian year expose the surface modules and its sensitive electronics compartment to a wide range of hostile conditions. Additional constraints come from the transporting spacecraft, where heat can be exchanged only across small interfaces. The purpose of the thermal control system is to maintain nevertheless the electronics and battery temperatures within a narrow band. Contrasting demands of reduced heat leaks and effective dump of surplus heat require new technologies and advanced design concepts to be satisfied under strict mass limits imposed. The paper describes the design, development and testing activities of a thermal control concept including high performance insulation combined with an innovative Loop Heat Pipe system. Extensive thermal analyses using ESARAD / ESATAN have been run and hardware has been built, qualified and tested.
