 note = {The Institute of Space and Astronautical Science has launched the asteroid explorer, HAYABUSA on May 2003. HAYABUSA includes the world-first asteroid rover MINERVA which will explore the asteroid surface in 2005. MINERVA needs a battery because instantaneous power generation by solar cells is insufficient for the surface exploration and data transmission tasks such as image acquisition by the onboard cameras, movement by the onboard actuator, and communication with the mother spacecraft. The night semisphere of the asteroid will be a very cold environment with the temperature lower than minus 100 C. The rover is too small to keep the inside temperature high enough for the typical batteries to be saved. Also the temperature in the day semisphere will be hotter than 100 C. Thus the onboard battery needs the availability of wide temperature range. The rover adopts the electric double-layer capacitor as the onboard electric power storage device, which can be saved under the very cold environment. The electrolytic fluid of the capacitor was tuned considering the environment of the asteroid, which enables the degradation under the very hot temperature as small as possible. So the rover is provided the ability to pass the night and the life with a couple asteroid days. This paper reports the developed electric double-layer capacitor of MINERVA asteroid rover. The energy density of the electric double-layer capacitor is smaller than the typical primary or secondary batteries under the current technical status. But it will be improved in the near future and installation to another space mission with severe temperature demand will be possible., 資料番号: AA0047899141},
