1977年,在美国弗罗里达州的肯尼迪角发射了两艘无人驾驶的“旅行者”宇宙飞船,执行收集太阳系外层行星资料的任务。从1972年以来,“旅行者”计划的主任科学家,物理学家爱德华·C·斯通(Edward·C·Stone)就一直指挥着人类有史以来为时最长,也是最为成功的行星探索。这位美国加州理工学院的物理学教授,到1989年,已经协调了多达230人的国际科学家小组的力量,由美国国家航空和宇航局提供资助,由位于帕沙第纳(Pasadena)的该学院的喷气推进实验室组织实施,分析由“旅行者”获取的图像和其它资料。这次任务,最初打算持续大约5年的时间。在这样一段时间里,只能够探索木星和土星。但是在斯通的率领下却成功地把飞船的寿命延长到人们的预料之外,使“旅行者”在这次引人注目的旅行中,能够同天王星和海王星进行首次相会,并有了许多新的重要发现。
In 1977, two unmanned “Traveler” spacecraft were launched at Kennedy Point, Florida, USA, to perform the task of collecting information on the outer planets of the solar system. Since 1972, the lead traveler physicist and physicist Edward C. Stone has directed the longest and most successful planet in human history ever. The professor of physics at the California Institute of Technology, by 1989, has coordinated the strength of a team of international scientists of as many as 230 people funded by the National Aeronautics and Space Administration of the United States of America, funded by NASA in Pasadena The Institute’s Jet Propulsion Laboratory organizes the analysis of images and other materials captured by Travelers. This mission, initially intended to last about five years. For such a period of time, only Jupiter and Saturn will be explored. But under the leadership of Stone, it succeeded in extending the longevity of the spacecraft beyond people’s expectations, enabling Travelers to meet for the first time with Uranus and Neptune during this spectacular trip. Many new important discoveries.
