"The Earth is the cradle of humanity, but mankind cannot stay in the cradle forever."—Konstantin Tsiolkovsky "In order for us to have a future that's exciting and inspiring, it has to be one where we're a spacefaring civilization."—Elon Musk In this course, we explore becoming spacefarers, colonizing our solar system. Why should we? An exploration of the economic, existential threat, and manifest destiny reasons. How should we? A primer on the history, science, technology, biology, and challenges of human spaceflight. Where should we? Possible solar system destinations for humanity. What then? The challenges and rewards of solar system colonization and terraforming. Finally, what should be the future of humanity in the cosmos? How do we get there? There are equations in this course, but they are few in number, and mathphobics should be able to follow along anyway. Unfortunately, our universe is mathematical, but I promise to use it gently and infrequently. | Lecture + Q&A.
