Research summary

The Late Heavy Bombardment (LHB) is a period of unusually high asteroid and comet flux hypothesized to have affected the entire inner Solar System hundreds of millions of years after its formation. If it occurred, the LHB has important implications for when and how life on early Earth developed. While nearly all evidence for the LHB has been erased from the Earth’s surface through the action of plate tectonics, the geologic stability of the Moon has allowed for billions of years of impact events to be preserved on the lunar surface. I am collecting new, high fidelity geochemistry datasets from lunar meteorites originating from the far side of the Moon and experimentally shocked lunar analogue materials. My approach will allow me to reconstruct the thermal histories, and consequently the impact histories, of these lunar samples and determine whether there is evidence for the LHB on the Moon’s far side.
