2.	Laboratory simulation of space weathering and water formation caused by solar wind proton on lunar and planetary surface.

Research summary
Lunar & Planetary exploration and space weathering effect We can estimate the composition of lunar and planetary surface using near-infrared spectra. However, optical properties of lunar and planetary surface are changed by space weathering effect, and this change affect to estimate of surface composition. Additionally, OH and/or H2O are formed due to interaction between minerals and irradiated solar wind protons at lunar surface. So, I simulate and investigate the spectral changes and water formation mechanism using ion irradiation equipment and infrared spectrometer.

Present specialized field
Moon, Asteroids (Keyword：Lunar & Planetary Exploration,Lunar water,Space weathering)
