Outline of Final Research Achievements

Predominant geological feature Rupes on Mercury are analyzed using image and altitude data by NASA MESSENGER Mercury mission. The rupes are presumably formed by crust shrinking globally considering their distribution on large circles of Mercury and large offsets of rupes. Rupes on the Moon are comparably investigated on their distribution and offset magnitude. I concludes lunar rupes are locally formed in margin area of Mares solidifing magma.
Results of this study are also used to make observation program in next Mercury exploration Bepi-Colombo project.
