Research Abstract

In order to investigate the time behavior of impact flux, I performed size-frequency measurements of small craters on ejecta blankets of lunar fresh craters using high-resolution images obtained by Kaguya and Lunar Reconnaissance Orbiter. The measured crater size-frequency distributions have a steeper slope in the diameter range of D <= 100 m compared to previous production functions. Using new crater production function, I derived the relationship between the crater frequencies and the absolute ages, suggesting that the cratering rate decreased with time.
