人类对太空的热情越来越高涨,一方面源于人类对未知领域的好奇心,一方面也源于人类对外星资源的渴望。许多科幻片都曾描述过人类到外星球开矿致富的故事,虽然要实现外星发财的梦想尚需时日,但是这样的故事并非空穴来风,因为天文学家发现了越来越多的太空矿藏。 The enthusiasm of mankind in space is getting higher and higher, on the one hand from human curiosity in the unknown field, on the one hand, and also from the human desire for extraterrestrial resources. Many science fiction films have described the story of human beings making their fortunes to the outer planet. Although it may take time to realize the dream of making extraterrestrial fortunes, such stories are not groundless because astronomers have discovered more and more space minerals.
