Science Fiction Greats on Humanity’s Destiny in Space

Philosopher Rebecca Lowe joins us to explore how the ideas of classical liberalism can provide fresh insight into humanity’s activities in space. Our conversation explores the philosophical tensions between individual freedom and societal good, the instrumental and intrinsic value of space activities, and the uniquely accessible nature of space science and exploration. From a novel approach to lunar property rights and the opportunities to support human flourishing, Lowe offers a thought-provoking vision of how philosophical traditions can inform our cosmic ambitions.

Space Policy Edition: Locke, liberty, and the pursuit of happiness (in space)

NASA’s OSIRIS-REx mission has returned pristine samples from asteroid Bennu to Earth, and the early results are remarkable. Sample analysts have confirmed the presence of abundant organic compounds, nitrogen-rich material, and evidence of past liquid water, all key ingredients that could help us understand the role asteroids played in delivering the building blocks of life to Earth. This week, we’re joined by Scott Sandford, co-investigator on OSIRIS-REx and a research scientist at NASA’s Ames Research Center. He explores the first two sample analysis papers published by NASA’s OSIRIS-REx team. Then, Bruce Betts joins us for What’s Up, where we look back at humanity’s history of sample return missions.

Twenty years ago, NASA’s Genesis spacecraft returned to Earth carrying precious samples of the solar wind, only to crash-land in the Utah desert. But that wasn’t the end of the mission. Amy Jurewicz, Assistant Research Professor Emeritus at Arizona State University and former project scientist at NASA’s Jet Propulsion Laboratory for the Genesis team, takes us inside the mission’s highs and lows, from its Apollo-inspired origins to its contributions to cosmochemistry and space weather. We discuss what this mission taught us about future sample returns, spacecraft protection, and long-term human spaceflight beyond Earth’s magnetosphere. Then Bruce Betts, Planetary Society chief scientist, joins for What’s Up and a look back at the history of sample returns.
