从阿波罗11号宇宙飞船1976年7月登月以来,至阿波罗17号为止,美国共登月六次(阿波罗13号计划失败),宇航员从月球表面各处采取了岩石试样,带回地球。这些试样在世界约150个研究单位进行了岩石矿物学、化学和物理学分析。月球岩石大致分为三种:月火成岩、月细砂和月凝灰岩。这些岩石中夹杂着直径为0.1毫米至1微米的金属颗粒,其中的强磁性成分主要是
From the Apollo 11 spacecraft’s lunar landing in July 1976 to the Apollo 17, the United States altogether toured the moon six times (the Apollo 13 program failed) astronauts took rock samples from all over the moon’s surface, Bring the earth back. These samples were subjected to rock mineralogy, chemical and physical analysis in about 150 research units around the world. Moon rock is divided into three types: lunar igneous, fine sand moon and tuff. These rocks are surrounded by metal particles with a diameter of 0.1 mm to 1 μm, of which the ferromagnetic components are mainly
