9月13日凌晨,美国航空航天局宣布,“旅行者1号”探测器目前已经飞出了太阳系,成为第一个进人星际空间的人造物体。“旅行者1号”是1977年发射的,如今在距离太阳125个天文单位的位置(地球与太阳之间的距离为一个天文单位,约为1.5亿公里)。它就像一个旅行家一样,但这场旅行没有终点。一般的空间探测器只有30年寿命,“旅行者1号”已进入“期颐之年”。不过当时为它配置了核能电池,能让它工作36年。为省电,从2007年开始,一些仪器被关闭,现在只留下紫外线探测设备,直到2025年核电池才能耗尽。之后,它会继续在星际空间游荡,没有人知道它将到达哪里。但如果接收不到信号,那一切都没有意义。目前“旅行者1号”发回
On the early morning of September 13, NASA announced that the “Voyager 1” detector has now flown out of the solar system and became the first man-made object to enter interstellar space. “Traveler 1” was launched in 1977 and is now located at 125 astronomical units away from the Sun (the distance between the Earth and the Sun is an astronomical unit of about 150 million kilometers). It’s like a traveler, but there’s no end to the trip. The general space probe has only 30 years of life, “Traveler 1 ” has entered the “period of the year ”. However, when it was equipped with nuclear batteries, it can work 36 years. To save electricity, some instruments have been shut down since 2007, leaving only UV detection equipment until nuclear cells can be depleted by 2025. After that, it will continue to wander in interstellar space, no one knows where it will arrive. But if it does not receive the signal, it makes no sense. Currently “Traveler No. 1” sent back
