The analysis of lunar samples returned to Earth by the Apollo and Luna missions changed our view of the processes involved in planet formation. The data obtained on lunar samples brought to light the importance during planet growth of highly energetic collisions that lead to global-scale melting. This violent birth determines the initial structure and long-term evolution of planets. Once past its formative era, the lunar surface has served as a recorder of more than 4 billion years of interaction with the space environment. The chronologic record of lunar cratering determined from the returned samples underpins age estimates for planetary surfaces throughout the inner Solar System and provides evidence of the dynamic nature of the Solar System during the planet-forming era.
对阿波罗号和月球号任务带回地球的月球样本进行的分析改变了我们对行星形成过程的看法。从带回的月球样本中获得的数据揭示了在行星生长过程中高能碰撞的重要性，这些碰撞导致了全球性的熔融。这种剧烈的诞生决定了行星的初始结构和长期演化。一旦度过形成期，月球表面就成为了超过 40 亿年与空间环境相互作用的记录者。从返回样本中确定的月球陨石坑形成的年代记录支持了内太阳系行星表面的年龄估计，并提供了行星形成时期太阳系动态性质的证据。
