    Research Interests:

    @   We study the origin and the evolution of planets in the solar system including the Earth, satellites and asteroids, by laboratory experiments and planetary explorations. Particularly, we focus on the impact phenomena which are an important factor to clarify the origin and the evolution of the solar system, and examined the relationship with the variety of bodies in the solar system.
       Currently, we collaborate with the researchers in ISAS, JAXA, PERC in Chiba Tech., Kouchi Univ., Univ. Occup. Env. Health, Aichi Toho Univ., etc., and develop the devices, SCI (Small Carry-on Impactor) and DCAM3 (Deployable Camera), equipped on Hayabusa-2 explorer.

    EXP


    a) Ground experiments of SCI (Small Carry-on Impactor) equipped on Hayabusa-2
    b) Impact cratering experiments in laboratory (Target: 100-μm glass beads)
    c) Impact experiments of equal-sized gypsum spheres
    d) Two-stage gas gun (A projectile can be accelerated at the highest impact velocity of 7 km/s !!)
    e) Illustration showing our study scope. "Missing link" means the mysterious zone in which the evolution
       processes are not clarified yet.



    Current Projects:@

    • Basic research for the proposal of planetary exploration spacecraft and impact experiments in space missions
    • Collision processes in planetesimal formation and evolution
    • Formation of craters and regolith deposition on asteroids and small icy bodies
    • Evolution of glaciers, ice sheets, and permafrosts on Mars
    • Origin and evolution of Jovian and Saturnian icy satellites, comet nuclei, and Kuiper Belt Objects (KBOs)
    • Origin and distribution of interplanetary dust
    • Classification of asteroid based on infrared observations
