Automated precision counting of small lunar craters – A regolith evolution model.

I will be presenting at the European Lunar Symposium 16th-21st June 2024.

This article is available for members to view in the Mercury section. 


Introduction: Lunar craters as small as 2.5m in diameter have been counted at many sites  cross the lunar surface, mainly mare ones [1]. The very large counts allow them to be plotted as size frequency histograms (CSFH), rather than cumulative distributions, enabling  subtle differences between sites to be more clearly revealed. The results for the ejecta blanket of Giordano Bruno crater, combined with current cratering rates determined by temporal imaging [2], are consistent with its age being about 10Ma [3], confirming that even  the very smallest craters formed during this period still exist today.
