美国航空航天局近日宣布,放弃唤醒“勇气号”火星探测器,取而代之的“好奇号”正在紧锣密鼓地研制中,但设计样式可能有根本的改变。火星探测车的昂贵造价及其不能令人满意的表现,使美国科学家对以轮式滚动的方式登陆地外星球的做法产生怀疑。研究证明,让稳定善行的“机器虫”充当探测工具,可能是不错的选择。 NASA recently announced that it is in full swing to abandon the awakening Mars Spirit and replace it with “curiosities.” However, the design style may have fundamentally changed. The high cost of Mars exploration vehicles and their unsatisfactory performance cast doubts on American scientists’ landing on alien planets by means of wheeled scrolls. Research proves that it may be a good idea to have a stable “good machine worm” as a sounding tool.
