Cosmos: A Personal Voyage (1980)

S1E5 Blues for a Red Planet

Could there be life on Mars? Dr. Sagan invites viewers on a journey across the red planet, starting with the imaginative visions of science fiction writers and then transitioning to the stark reality captured by two Viking spacecraft. Since 1976, these probes have transmitted thousands of breathtaking images of Mars' terrain back to Earth. While drawing on insights from earlier missions, Sagan's evaluation remains relevant and thought-provoking.
