Panel Selection: Inner Planets: Mercury, Venus, and the Moon.
Institution: Southwest Research Institute
We discuss our priorities for exploring the Moon''s bombardment history: (1) Test the idea of a massive impactor spike 3.8-4.0 billion years ago. (2) Anchor the early Earth-Moon impact flux curve by determining the age of South Pole-Aitken Basin. (3) Establish a precise absolute chronology.
