High-energy particles and ions such as micro meteorites and solar wind are falling on the surface of an airless body, and space weathering that alters the surface material is occurring. Space weathering appears mainly as a change in optical properties. The mechanism was revealed by returned samples from an asteroid and moon. Research on space weathering has been progressing by simulation experiments for reproducing space weathering. In this paper, we will summarize what has been clarified so far, and look forward to future space weathering research.
