Assessing the Recent Impact Flux in the Inner Solar System: 1 Ga to Present
The Moon’s craters record the flux of impactors in the inner solar system. We focus on understanding the flux over the past 1 Ga, which multiple lines of evidence suggest has not been constant. We recommend a multi-pronged approach to addressing gaps in our knowledge of this flux and its consequences for all inner solar system bodies.
