Rockets Get Us to Mars. Biology Decides If We Can Stay | Ryan T. Scott of NASA AMES | Ep. 44

<p>In this episode, NASA space biologist Ryan T. Scott explains why biology, not rocket science, is the real limiting factor in humanity’s goal of becoming a multi-planetary species. We discuss how NASA’s Open Science Data Repository (OSDR) is transforming space biology by making decades of multi-modal data openly available, standardized, and reusable.</p><p><br /></p><p>Ryan breaks down why studying hazards like microgravity and radiation in combination (instead of in isolation) is critical for long-duration missions to the Moon and Mars. He also shares how open data and AI are accelerating discoveries, how high school students are now publishing peer-reviewed NASA space biology papers, and what it will actually take, biologically, for humans to thrive beyond Earth.</p><p><br /></p><p>If we want to become a true spacefaring civilization, we need to treat biology as seriously as propulsion. This conversation goes deep into the data infrastructure, research gaps, and mindset shifts required to make that future possible.</p><p><br /></p><p>List of studies cited:</p><p><br /></p><p>1.
