Abstract
Emerson Speyerer and co-authors use 14,092 temporal ('before and after') image pairs obtained by NASA's Lunar Reconnaissance Orbiter to quantify the contemporary crater-production rate on the Moon. They identify broad reflectance zones associated with the new craters that they interpret as evidence of a surface-bound jetting process, and estimate that this secondary cratering process is churning the top of the regolith much faster than previously thought.
