Research in the area of “Emerging Worlds” aims to answer the fundamental science question of how the Solar System formed and evolved. It helps to advance the strategic science goal to “explore and observe the objects in the Solar System to understand how they formed and evolve” through basic research that supports planetary exploration, aids in the development of missions, and provides context for the interpretation of all Solar System observations that are relevant to its formation and evolution. Major interdisciplinary efforts to solve key questions are particularly valued.

A wide range of investigations will be covered, including, but not limited to, theoretical studies, analytical and numerical modeling, sample-based studies of extraterrestrial materials, laboratory studies, and synthesis of previous work.
