This project aims to determine precise timing of formation and primary melting of asteroids of various compositions, and to trace the stellar sources and mixing processes that caused the compositional diversity of asteroids and planets in our Solar System. This can be attained by comprehensive study of achondrites, meteorites derived from asteroids that were once partially melted. Using the world’s foremost facilities for cosmochemical research in Australia and the United States of America, the processes leading to the formation of planets will be explored. This project is intended to advance fundamental knowledge of the environment in which planets emerge and evolve, and the place of our Solar System among planetary systems in the Galaxy.

该项目旨在确定各种成分的小行星形成和初次熔化的精确时间，并追踪造成太阳系小行星和行星成分多样性的恒星来源和混合过程。这可以通过对无球粒陨石的全面研究来实现，无球粒陨石是来自曾经部分熔化的小行星的陨石。将利用澳大利亚和美利坚合众国世界上最先进的宇宙化学研究设施，探索行星形成的过程。该项目旨在促进对行星出现和演化的环境以及我们太阳系在银河系行星系统中的位置的基本知识。
