| Research Abstract |
By using newly obtained image data acquired by Japanese lunar exploration mission, Kaguya, and Lunar Reconnaissance Orbiter (USA), I revisited a crater production function which has been produced in the early 1980s.As a result, newly obtained crater production function in the range from present to 3 Gyr ago corresponds approximately to previous research. On the other hand, I found that the effect of secondary crater on the Apollo 15 landing site that was researched by Neukum is not negligible, so, it is necessary to evaluate the crater production function of older area before than 3 Gyr ago.
