Lunar surface is coverd with the lunar regolith that is a kind of microscopical powder. Considering landing mission of lunar probe on such a terrain, it has some risks, therfore, we should conduct verification experiments for the analysis of landing behavior to achieve the mission. However, if we execute verification experiments on the earth, there are major differences between the moon and the earth, the atmosphere (air or vacuum), the lunar terrain and the gravity acceleration. In generally, the vaccum atmosphere and lunar terrain can be reconstructed to use the vacuum chamber and the lunar regolith simulant. On the other hand, it is possible to reconstruct the lunar gravity acceleration by airplane or semi-free-fall tower, but it is not easy. In this paper, we suggest the scaled model as a simple way of the reconstruction of the lunar gravity.
