On Sunday, several hundred engineers and scientists will gather at the Jet Propulsion Laboratory in Pasadena, Calif., and await the end of the Galileo spacecraft in a suicide plunge into Jupiter''s dense atmosphere. 周日,数百名工程师和科学家,将聚集在加利福尼亚州的帕沙德纳的喷气推进实验室,静候伽利略号航天飞机自杀性插入木星周围稠密大气层的结局. They are the kind of professionals who try to resist anthropomorphizing their machines, even one like Galileo, which has been a longtime companion in their lives and careers. But they freely concede that they will be there at the end as an act of homage. 这些专家尽力阻止使机器人性化,即便是相处很久的伽利略号.但他们不得不勉强的承认他们会满怀敬意的守到最后时刻. It will be the equivalent of a wake, said Dr. Claudia Alexander, manager of the project. “它将是一个有意义的轨迹”,这个项目负责人Claudia Alexander博士评论道. Few flight teams have had to contend with a spacecraft more demanding of their attention and ingenuity. 很少飞行队要求航空飞船有更多的注意力和灵活性. Launched in 1989 after a long delay caused by the loss of the space shuttle Challenger in 1986, Galileo took six years going to Jupiter, almost half a billion miles away, by a circuitous route dictated by the limited power of its initial rocket boost. 由于1986挑战者号航空飞船的坠毁,推迟了很久的伽利略号终于于1989年发射.它花了6年的时间到达木星,几乎走了5亿英里距离. From then on, the three-ton spacecraft was tormented by as many afflictions as poor Job. 从那时起,3吨重的航空飞船被认为是一项要多痛苦有多痛苦的乏味工作 The main antenna, the one that scientists counted on for the return of pictures and data of Jupiter and its four largest moons, failed to unfurl. Engineers had to rely on a smaller antenna and an improvised system of data shorthand. 科学家们所指望的用于返回木星和他的四个最大的卫星的图片和数据的主要天线没能正常打开,因此他们不得不依靠一个小型天线和一个临时准备的数据速记系统. Galileo was further hobbled by an erratic tape recorder. After the craft began orbiting Jupiter in 1995, repeated zappings from the planet''s intense radiation belts damaged other instruments. 伽利略号又被一个漂浮在太空的磁带录音机所拖累.在飞船1995年后围绕木星轨道运动时,从行星的强辐射带发射的循坏的跳过节目的辐射损坏了其他一些仪器. In nearly all cases, engineers managed to reprogram software to overcome or work around the setbacks. As recently as last November, in its last encounter with a Jovian moon, tiny Amalthea, the spacecraft got hammered again by radiation, Dr. Alexander said. 在所有的情况中,工程师们试图重新编写软件以克服遇到的挫折.去年十一月份,在它的最后一次与木星的卫星木卫五相遇时, “飞船又被辐射给破坏了,” Alexander博士说. The spacecraft''s fault-detection system came to the rescue once again, turning off nearly all operations and saving the science data from the encounter. 飞船的错误监察系统再次起了作用：它几乎关闭了所有操作并将相遇的全部科学数据记录了下来. But the tape recorder was left stuck. Flight controllers applied electrical current to the recorder, on and off and on again, repeatedly, until the molecular structure was altered enough to unstick the recorder for transmitting data. 但是磁带记录机却粘着了.飞行控制器应用了电流将记录机反复地打开关上,直至分子结构改变才使磁带与记录机分开.
