This is Radio Sputnik.

"It was the sound of wonder and foreboding. Nothing would ever be quite the same again -- in geopolitics, in science and technology, in everyday life and the capacity of the human species." On the eve of its fiftieth anniversary (Oct. 4), the NYT remembers the Sputnik launch. "It was an unprepossessing agent of alarm. A simple sphere weighing just 184 pounds and not quite two feet wide, it had a highly polished surface of aluminum, the better to reflect sunlight and be visible from Earth...The Russians clearly intended Sputnik as a ringing statement of their technological prowess and its military implications. But even they, it seems, had not foreseen the frenzied response their success provoked."
