旅行者1号和旅行者2号于1977年发射，开始了太阳系外行星的盛大旅行。它们已经成为运行时间最长、离地球最远的航天器。两者都超越了日球层，这是由太阳风和太阳磁场影响所定义的领域。在旅行者1号和2号驶向恒星的第45个年头，它们分别到达了距离太阳近22光小时和18光小时的地方，仍然是目前唯一探索星际空间的航天器。每艘飞船都携带一个12英寸的镀金铜盘，上面记录着声音、图片和信息。金唱片旨在传达地球上的生活和文化故事，保存在一种可以在星际旅行中存活10亿年的介质中。

Voyager 1 and Voyager 2 were launched in 1977 on a grand tour of the outer planets of the Solar System. They have become the longest operating and most distant spacecraft from Earth. Both have traveled beyond the heliosphere, the realm defined by the influence of the solar wind and the Sun's magnetic field. On the 45th year of their journey toward the stars Voyager 1 and 2 reached nearly 22 light-hours and 18 light-hours from the Sun respectively and remain the only spacecraft currently exploring interstellar space. Each spacecraft carries a 12-inch gold-plated copper disk with recordings of sounds, pictures and messages. The Golden Records are intended to communicate a story of life and culture on planet Earth, preserved in a medium that can survive an interstellar journey for a billion years.
