Once the existence of this wave-length had been discovered, it was not long before its use as the uniquely recognizable broadcasting frequency for interstellar communication was suggested.

一旦这种波长的实际存在被发现，提出把它作为星际间唯一可辨认的广播频率就为期不远了。

If I hack a tiny bit of code, just 20 instructions in the rover's operating system, NASA can link the rover to Pathfinder's broadcasting frequency and we're in business.

如果我编一段程序只用将 20 条指令输入到操作系统，NASA 就能把探测车和探路者通讯频率联上搞定了。
