Host: The Japanese Society for Planetary Sciences: Local Organizing Committee for 2007 Fall Meeting
We are investigating next missions of Hayabusa, which is the sample return mission from Asteroid Itokawa. Itokawa is an S-type asteroid, so next targets are C or D-type asteroids or dormant comets. Such objects are important from the scientific point of view. Also we should plan new mission so that we can get much more products. In this paper, we summarize what we have discussed about our new mission to primitive bodies in the solar system.
