约1吨重的美国太空探测器“旅行者2号”,在太空中邀游了12年,几乎闯荡了半个太阳系,今年8月24日,在覆盖着凝冻的甲烷云层的海王星北极区上空4800多公里处掠过,近距离访问了这颗太阳系中神秘的第八行星。紧接着马不停蹄,继续以每小时几万公里的速度向太阳系的边陲飞去。据科学家估计,它还能继续工作25年,在太空中进行紫外天文考察,寻找太阳系的边缘,向远在几十亿、几百亿公里之外的一个亮点——地球母亲发回各种科学数据。一旦油干灯
Approximately one ton of US space probe “traveler 2” has been invited to space for 12 years and has almost half a solar system. On August 24 this year, over the Neptune Arctic, covered with frozen methane clouds, Over 4800 kilometers swept past and visited the mysterious eighth planet in this solar system. Immediately afterwards, they continued to fly to the fringes of the solar system at the speed of tens of thousands of kilometers per hour. It is estimated by scientists that it will continue to work for 25 years and carry out an ultraviolet astronomy investigation in space to find the edge of the solar system and send back a variety of sciences to Mother Earth as a bright spot beyond billions and tens of billions of kilometers away data.
