After Venus, Mars is the planet visited in this episode. Sagan shows the fascination with the red planet since HG Wells's War of the Worlds (1866-1946), and his own fascination with the novels by Edgar Rice Burroughs (1875-1950) from Barsoom's series, showing some illustrations by Michael Whelan (1950-). Thus Sagan moves on to the fanciful notes of Percival Lowell (1855-1916), followed by Robert Goddard's (1882-1945) rocket development until the launch of the Viking 1 and Viking 2 probes, which sought signs of life on the planet. red. At this point, the experiment of his late friend Wolf V. Vishniac (1922-1973) is remembered as a possibility of finding life on Martian soil, as well as the rover project elaborated by the Rensselaer Polytechnic Institute. Finally, Sagan speculates about a theoretical terraforming on Mars that could eventually melt the ice of the Martian ice caps, returning to the fanciful channels of Percival Lowell reported earlier in the episode.
