陆地资源的日益枯竭,迫使人类把目光投向了深深的海洋和遥远的小行星;科幻小说中的场景成为现实的日子已经不远了。登陆小行星当地球资源即将被耗尽的时候,人类是否可以去小行星上采矿?这听起来像是好莱坞科幻大片《阿凡达》中的情节,也是科学界讨论已久的话题。随着人类终于拥有了能从外太空获取资源的技术,这种一直被认为是空想的场景,或许在不久的将来就可以变为现实。事实上,还真有一批欧美宇航员正在接受训练,为的是登陆小行星,并在其表面勘探矿产资源。他们甚至还在学习一旦小行星对地球构成威胁时,如何将其摧毁的技巧。
The depletion of land resources has forced humanity to turn its attention to the deep oceans and distant asteroids; the scenes of science fiction no longer have come to reality. Landing on an asteroid When the earth’s resources are about to be depleted, can humans mine on an asteroid? This may sound like the plot in the Hollywood science fiction blockbuster Avatar, a long-discussed topic in the scientific community. As humans have finally acquired the technology to source from outer space, this scenario, which has long been considered utopian, may become a reality in the near future. In fact, there are really a group of European and American astronauts who are currently training to land on an asteroid and explore mineral resources on its surface. They are even learning how to destroy an asteroid when it poses a threat to the Earth.
