The Estimated Timelines of the Impact Rate at the Early Solar System

Caption

An intense spike at ~3.9 Ga (LHB) was previously expected (the dashed curve 'a'), mainly based on lunar and some meteorites data. This study reports the earlier impacts (~4.4 - 4.15 Ga) from Vesta's rocks, suggesting that the timeline should be modified (probably like the curve 'b').
