Abstract
The degradation states of lunar impact craters are significant information to identify the eruption age of lunar maria. The terrain camera (TC) installed on SELENE will provide high-resolution (10m/pixel from the SELENE 100km altitude) stereo images of the lunar surface that are required on the detailed study of lunar crater morphology. We discuss the possibility of study of lunar crater degradation status by TC data on the basis of the recent results of TC flight model tests.
