Overview:A 3-man team visit the Lunar Observatory, isolated from all Earth signals on the Moon's far side, for routine Radio Telescope work. They pass the time during a long sky-mapping session by taping "A glimpse of lunar life" sound-broadcast. An power fault interrupts and requires a Moon walk to the Radio Telescope. One man is badly injured while returning. Unconscious for days, he responds to the tape-recording and deliriously asks to hear the "sound from the stars." His colleagues comply and make an interesting discovery.
