Over the last ten years, 100 Year Starship brought together, at the symposia, some of the brightest minds in fields as varied as cosmology, medicine, policy, propulsion, finance, anthropology, navigation, and textiles, to discuss and advance the possibilities of deep space travel-beyond our sun to another star.

This is a collection of many of the best papers from these symposia, covering a wide range of topics, including propulsion, life systems, and societal impacts. These papers represent the cutting-edge thinking and research on achieving human interstellar travel and provide a glimpse into the extraordinary future of space exploration and the benefits (and perhaps risks) to life here on Earth.

Whether you are an academic researcher, a space enthusiast, or someone interested in the future of humanity, here are possibilities that may await us as we embark on the journey to reach another star.
