Research in the area of Emerging Worlds aims to understand the formation and early evolution of the Solar System. The central goal of the program element is to understand how the Sun’s family of planets, satellites, and minor bodies (including small bodies and rings) form and evolve. NASA is particularly interested in research projects that closely support its mission for exploring the Solar System, contribute to the development of future missions, or involve major interdisciplinary efforts to solve key questions. A wide range of investigations will be covered, including theoretical studies, analytical and numerical modeling, sample-based studies of extraterrestrial materials, laboratory studies, data synthesis, and observational studies of objects outside of our Solar System relevant to the formation of planetary systems.
