Remote sensing is the necessary method to explore the moon and planets. Small planets such as moon and asteroids do not have the biological obstacles and atmosphere which absorb electromagnetic reflection and emission. The moon and asteroids have the naked surface of rocks and regolith to be measured the surface characteristics by remote sensing. The important resource materials can be obtained in the space as water and helium-3 which will be used for the future nuclear fusion reactor rather than rare metals and unknown minerals. The constructive materials are also the candidates of resources in the space. The resources in the space will be constrained by the type of industries and human activities in it.
