人类对地外物质的研究手段,一种是大气外观测,即通过各种空间探测器及空间实验室对太阳系各天体进行观测,或着陆就地探测;另一途径是地面观测和实验室研究。地面实验室研究,主要通过两种途径获得地外物质样品,一是人工方法,如登月取样、火箭穿透和高空气球与飞机收集宇宙尘埃,再返回地面;或地外物质通过自然过程降落在地表,如陨石的收集,海底沉积物、极地冰层和古老地层中搜集宇宙尘。我国已收集到81次陨石,在沿海沉积
Human research methods of extraterrestrial material, one is the appearance of the atmosphere, that is, through various space probes and space laboratories to observe the celestial bodies of the solar system, or landing in situ detection; the other way is the ground observation and laboratory studies . Ground laboratory research, mainly through two ways to obtain extra-terrestrial material samples, first, artificial methods, such as lunar sampling, rocket penetration and high-altitude balloons and aircraft to collect cosmic dust, and then return to the ground; or extraterrestrial material by the natural process of landing Collect cosmic dust on the surface, such as meteorite collection, seabed sediments, polar ice and ancient formations. China has collected 81 meteorites, deposited in the coastal areas
