Abstract
This paper presents a mission scenario and a system concept of Lunar Mobile Explorer (LME) in late 1990’s, using H-II, the Japanese coming launch vehicle. Also described is the conceptual study of LME about the guidance navigation, and control (G&C) system and the communication system. In the early stage of the lunar development, it is necessary to make a detail map of the moon resources and topography, and to get the data for planning of human activities, which expects obtaining the number of Lunar bases, to decide good places for locating these bases, to estimate a scope of robot application. Then, it is appropriate to send an unmanned explorer on the moon in order to get a large amount of data. It is better choice to use mobile explorer, because no standstill can obtain the abundant data except LME.
