Voyager 2 at 12,000 Days: The Super-Marathon Continues
本帖最后由 MBR 于 2010-7-7 21:20 编辑NASA's plucky Voyager 2 spacecraft has hit a long-haul operations milestone today (June 28) -- operating continuously for 12,000 days. For nearly 33 years, the venerable spacecraft has been returning data about the giant outer planets, and the characteristics and interaction of solar wind between and beyond the planets. Among its many findings, Voyager 2 discovered Neptune's Great Dark Spot and its 450-meter-per-second (1,000-mph) winds.
旅行者2号探测器创造了一个新的里程碑---连续飞行了12000天。在将近33年的时间里,这艘古老的飞船传回了许多地外行星的数据,以及其与太阳风相互作用后的特征。在旅行者2号探测器的众多发现中,包括了1989年8月25日人类首次对海王星的造访。在那次的接触中,发现了位于海王星南半球的沿逆时针方向自传的大黑斑,黑斑的大小大约是木星大红斑的一半,其内部风速高达450米每秒。
The two Voyager spacecraft have been the longest continuously operating spacecraft in deep space. Voyager 2 launched on August 20, 1977, when Jimmy Carter was president. Voyager 1 launched about two weeks later on Sept. 5. The two spacecraft are the most distant human-made objects, out at the edge of the heliosphere -- the bubble the sun creates around the solar system. Mission managers expect Voyager 1 to leave our solar system and enter interstellar space in the next five years or so, with Voyager 2 on track to enter interstellar space shortly after that.
到目前为止,两艘旅行者探测器是深空中连续可控运行时间最长,同时也是距离地球最远的人造物体。旅行者二号于1977年8月20日发射,当时的美国总统还是吉米卡特。旅行者一号于两周后发射,9月5日。现在,探测器的位于日光层(太阳气层)的边缘,是由太阳将太阳风(具有带电粒子)吹向太阳系周围产生的日光层气泡,囊括了整个太阳系,是太阳风与星级物质相互作用的边界线。对探测器的任务预期估计,旅行者一号探测器将在下一个五年左右率先离开太阳系,进入星际空间,旅行者二号则紧随其后,闯荡险象环生的茫茫星际。
Having traveled more than 21 billion kilometers (13 billion miles) on its winding path through the planets toward interstellar space, the spacecraft is now nearly 14 billion kilometers (9 billion miles) from the sun. A signal from the ground, traveling at the speed of light, takes about 12.8 hours one-way to reach Voyager 2.
旅行者二号探测器迄今已飞行了210亿千米(130亿英里),巧妙地利用行星间的引力向太阳系以外的星际空间飞去,探测器距离太阳140亿千米(90亿英里)。地面控制站的信号要经过12.8小时才能被接收。
Voyager 1 will reach this 12,000-day milestone on July 13, 2010 after traveling more than 22 billion kilometers (14 billion miles). Voyager 1 is currently more than 17 billion kilometers (11 billion miles) from the sun.
旅行者一号在飞行了至少220亿千米(140亿英里)后,将在2010年7月13日迎来一个新的里程碑—空间飞行12000个地球日,目前距离太阳170亿千米(110亿英里)。
The Voyagers were built by JPL, which continues to operate both spacecraft. Caltech manages JPL for NASA.
探测器由美国国家航空航天局喷气推进实验室加州理工学院负责项目管理

只要它还能工作,就继续工作下去。地球还能收到信号就可以。仪器方面不太清楚,应该是没有关闭什么仪器吧。 携带的相机是关了,其他的不清楚,主要维持个通信 不知道未来的飞船会不会追上它 -。-
