Is there life in the Venusian Clouds? Neil deGrasse Tyson and comic co-host Chuck Nice are joined by planetary astrobiologist David Grinspoon to discuss NASA’s return to Venus, our space future, and whether we’ll find life in our solar system. As a primary investigator on the upcoming DAVINCI mission, David explains why we haven't sent a dedicated U.S. mission to our sister planet since the 1980s and how the history of "space futures" has always been a reflection of our own culture and politics. Neil and David explore the evolution of our planetary visions, from the mass delusion of Martian canals and Jules Verne's moon voyagers to the propaganda efforts during and before the Apollo era. You'll learn how people once assumed every planet was inhabited, only to have their "cloud swamp" dreams shattered by the harsh reality of a runaway greenhouse effect. When did scientists realize Venus’s runaway greenhouse and that it wouldn’t have life? We get into the nuts and bolts of the DAVINC
