Sagan reflects on the future of humanity and the question of "who speaks for Earth?" when meeting extraterrestrials. He discusses the very different meetings of the Tlingit people and explorer Jean-Francois de La Perouse with the destruction of the Aztecs by Spanish conquistadors, the looming threat of nuclear warfare, and the threats shown by destruction of the Library of Alexandria and the murder of Hypatia. The episode ends with an overview of the beginning of the universe, the evolution of life, and the accomplishments of humanity and makes a plea to mankind to cherish life and continue its journey in the cosmos. The Cosmos Update notes the preliminary reconnaissance of planets with spacecraft, the fall of the Berlin Wall and the end of apartheid in South Africa, and measures towards the reduction of nuclear weapons.

Born of the Cold War, NASA moves stridently from disastrous rocket tests to the glorious conclusion of the Gemini Program. We experience the massive challenges of sending a man into space and how, despite many setbacks, the astronauts proved that the key element to exploration would be human resourcefulness, in space as well as on the ground. NASA veterans describe these early missions as the hardest of all - the first, uncertain steps towards a new frontier. Building on the success of the pioneering Mercury program, Project Gemini gives NASA the experience and confidence to take the next giant leap - to land men on the Moon.
