Early Evolution of the Solar System: A Planetary Perspective

A geochemical study of early solar system materials will be conducted to investigate physical conditions leading to assembly of the terrestrial planets, and the chronology of early geological events that shaped the Earth and Moon. Objects from the solar nebula and samples from the Earth, Moon, Mars, and differentiated asteroids will be studied. This research will contribute toward understanding the astrophysical environment of the inner solar system, establish a high-resolution absolute timescale for early geological events, and Identify the population of solid bodies present during the initial stages of planetary development.
