美国航天局近日宣布,放弃唤醒勇气号火星探测器,它的使命正式终结。取而代之的好奇号正在紧锣密鼓地进行研制,但设计样式可能会有根本的改变。火星探测车的昂贵造价与其不能令人满意的表现,使美国科学家对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 NASA recently announced that it has officially ended its mission of waning Mars rover. The curiosity replaced is being developed in full swing, but the design style may be fundamentally changed. The high cost of Mars rovers and their unsatisfactory performance have cast doubt on the way scientists in the US have wheeled the way to land on alien planets. Research proves that it may be a good choice to have a stable “good machine worm” as a detection tool
