The exploration of space resources will be a part of major space developments in the 21st century. Among the extraterrestrial bodies in the solar system, minor bodies, particularly asteroids, are very attractive targets, not only because of their scientific value but also because they are promising extraterrestrial resources for future exploitation. Recently, the growing international interest in these small bodies has resulted in many spacecraft exploration plans being proposed, and some of these are now in action. We have also proposed a mission concept for Phobos/Deimos exploration. We have attempted to apply some schemes originally developed for Earth remote-sensing data processing to the estimation of a small body's shape. In this paper we describe some preliminary results, which consist of three parts: (1) parallel matching experiment of control points between different images of the target body by computer simulation using large scale parallel processors; (2) application of an automatic shape recognition scheme to celestial shape estimation; (3) application of a massively-parallel processing scheme to crater recognition.
