论文摘要
彗星通过记录前验历史,行星形成的初始状态以及早期地球的益生元有机物和挥发物来对太阳系的奥秘。分析来自彗星核的返回样品将提供有关太阳系起始材料以及它们如何融合形成行星并促进生命的无与伦比的知识: 1。彗星是如何形成的? 2。彗星材料是原始的,还是经历了复杂的改变历史? 3。彗星中是否发生了水的变化? 4。彗星有机物的组成是什么? 5。彗星提供了地球挥发物的很大一部分? 6。彗星有机物是否有助于地球上的生命同源性? 7。在星际,卵形和行星环境中,复杂的有机分子如何形成和发展? 8。彗星可以告诉我们关于原始星云中材料混合的内容?
Comets hold answers to mysteries of the Solar System by recording presolar history, the initial states of planet formation and prebiotic organics and volatiles to the early Earth. Analysis of returned samples from a comet nucleus will provide unparalleled knowledge about the Solar System starting materials and how they came together to form planets and give rise to life: 1. How did comets form? 2. Is comet material primordial, or has it undergone a complex alteration history? 3. Does aqueous alteration occur in comets? 4. What is the composition of cometary organics? 5. Did comets supply a substantial fraction of Earth's volatiles? 6. Did cometary organics contribute to the homochirality in life on Earth? 7. How do complex organic molecules form and evolve in interstellar, nebular, and planetary environments? 8. What can comets tell us about the mixing of materials in the protosolar nebula?
