Shielding astronauts from cosmic rays, and planning the end of fossil fuels

Shielding astronauts from cosmic rays, and planning the end of fossil fuels

First up on the podcast, how do we protect astronauts when they leave the shelter of Earth’s protective magnetic fields and face the slow, constant bombardment of space radiation? Freelance science journalist Elie Dolgin joins host Sarah Crespi to discuss what we know about the damage from high-velocity particles and the research being done to curb their biological toll. Next on the show, modeling the fall of fossil fuels during the decarbonization of energy systems, with civil engineer and environmental sociologist Emily Grubert and historian and engineer Joshua Lappen, both at the University of Notre Dame. The pair wrote a policy forum on predicting chokepoints or “minimum viable scales” in the decline of fossil fuel networks—in effect, when a system might get too small to maintain its function. Understanding how to keep things online until they are no longer needed is important to maintain energy for all, as renewables grow and mines, pipelines, and refineries shrink.
