Pale blue dot : a vision of the human future in space : second draft

The second of twenty full drafts of Pale blue dot : a vision of the human future in space, published in 1994. Sagan discusses the history of astronomy and considers the future of humanity in space, arguing that it is necessary for humanity's survival to explore and ultimately terraform and create human settlements on planets and asteroids. The draft is made up of interleaved notes. These notes were transcribed from audio recordings dictated by Carl Sagan. The resulting assembled document was then extensively marked up and revised by Sagan. In cases where Sagan wrote notes on the back of printed pages those pages were digitized.
