　View Summary

Measuring shapes of asteroids is one of the significant objectives of asteroids missions. In order to measure shapes of asteroids, we have to decide asteroid's rotation axis. We have been investigating the methods to measure figure of Asteroids using the Orbital Motion Analysis system at CRL. Here, we report our investigation results for rotation axes-decision, by numerical calculation.

　View Summary

The changes of surface reflectance in response to changing illumination and viewing geometry, depends upon physical and optical properties of surface materials and overall shape of the body. We are trying to estimate the surface reflectance properties of Phobos using the computer graphic (CG) of detail model of Phobos, on which reflectance conditions can be freely changed. Here we report the system configuration and procedures of the simulation study.
