The Sounds of Venus

While the U.S. concentrated on landing probes on Mars, the Soviet Union sent a number of probes to Venus. One of them, Venera 14, had a microphone aboard. Above is a video with a soundtrack from Venera 14.

Not surprisingly the sound isn't all that interesting -- sadly, no outer-space monsters roaring in the background. However, the accompanying images from the surface of Venus are well worth a look.
