Cosmochemistry is the chemical analysis of extraterrestrial materials. This term generally is taken to mean laboratory analysis, which is the cosmochemistry gold standard because of the ability for repeated analysis under highly controlled conditions using the most advanced instrumentation unhindered by limitations in power, space, or environment. Over the past 40 y, advances in technology have enabled telescopic and spacecraft instruments to provide important data that significantly complement the laboratory data. In this special edition, recent advances in the state of the art of cosmochemistry are presented, which range from instrumental analysis of meteorites to theoretical-computational and astronomical observations.
宇宙化学是对天体物质的化学分析。这个术语通常是指实验室分析,因为它是宇宙化学的黄金标准,能够在高度受控的条件下使用最先进的仪器进行重复分析,不受电源、空间或环境的限制。在过去的 40 年中,技术的进步使望远镜和航天器仪器能够提供重要的数据,这些数据极大地补充了实验室数据。在这个特刊中,介绍了宇宙化学领域的最新进展,从陨石的仪器分析到理论计算和天文观测。
