Martians! draft script for Cosmos episode 5

Handwritten and typewritten voice-over scripts for the initial sequence of episode 5 of Cosmos, "Blues for a Red Planet." These focus on Mars as a "mythic arena" where imaginative science and science fiction have each shaped our understanding of the planet. Sagan discusses H.G. Wells and Edgar Rice Burroughs fictional writings about Martian life and civilization, Percival Lowell's work on Martian canals, the Viking Mars exploration program, and Robert Goddard's work on rocketry.
