美国航天局正在关闭旅行者1号和2号航天器上的两个科学仪器,以保存电力和延长飞行任务。 NASA is shutting down two science instruments on the Voyager 1 and 2 spacecraft to conserve power and extend their missions. Voyagers号于1977年发射, 现在位于星际空间, 旅行者在距离地球超过150亿英里的地方, 旅行者在距离地球超过130亿英里的地方, 旅行者在超过21亿英里的地方。 The Voyagers, launched in 1977, are now in interstellar space, with Voyager 1 over 15 billion miles from Earth and Voyager 2 over 13 billion miles away. 每个航天器仍拥有三种仪器来研究太阳的保护泡泡和外太空。 Each spacecraft still has three instruments to study the sun’s protective bubble and the space beyond. 必须关掉仪器,因为探测器每年失去大约4瓦的功率。 Turning off the instruments is necessary as the probes lose about 4 watts of power per year.
