Preliminary Thermal Design of the Japanese Mars Rover Mission
MetadataShow full item record
A Mars surface exploration working group in JAXA has been planning its first attempt to send a rover to the Martian surface for a technological demonstration and to engage in direct search for living organisms in Martian soil at Recurring Slope Lineae (RSL), where liquid water is believed to exist underground and flow out to the surface in the summer. A 150kg-class, stand-alone-type rover (without any mother lander or rover responsible for some roles such as communication) has been designed as a “clean rover” that excludes any radioisotope energy. This paper describes the mission overview and the results of the preliminary thermal design and analysis to show that the mission plan remains sufficiently feasible.
