Physical Study of Comets, Minor Planets, and Meteorites,ts. The commencement of spacecraft study of small bodies marks a new era in comet/asteroid science and, in coordination with ground- based and Earth-orbital observations, will result in unprecedented new knowledge about the origin of the solar system and about solar system processes.作者: 大廳 時(shí)間: 2025-3-22 01:38 作者: outer-ear 時(shí)間: 2025-3-22 07:08 作者: 龍蝦 時(shí)間: 2025-3-22 10:02
