旅行者1号(Voyager 1)是迄今为止飞得最远的探测器,该探测器于1977年9月5日发射升空,在接下来的时间里,它连续利用了木星、土星等巨行星的引力助推,进而获得了足以摆脱太阳引力束缚的速度,在此之后,它就一直在向宇宙深空前进,如果不出意外的话,在遥远的未来,它就可以飞出太阳系。 就目前的情况来看,旅行者1号已经飞了46年的时间,它当前的位置距离地球大约242亿公里,这大概相当于日地平均距离的162倍,对于我们人类来讲,这样的距离可以说是非常遥远了。 令人惊讶的是,这个探测器仍然与地球保持着联系,那么问题就来了,在这么远的位置上,它为什么还能和地球通讯呢? 是使用了什么“黑科技”吗? 其实并不是。
