X Minus One -- And the Moon Be Still as Bright

From NBC's landmark science fiction series X Minus One comes Ray Bradbury's haunting Martian Chronicles tale. The Fourth Expedition lands on Mars to find its ancient civilization gone -- wiped out by chickenpox carried from Earth. As his crewmates desecrate the silent ruins, the archaeologist Spender is consumed by grief and rage, and turns against his own men to defend a dead world's beauty. Adapted by Ernest Kinoy, it remains one of radio's most literate and unsettling broadcasts.
