We welcome Charles Swanson, Princeton PhD candidate in plasma physics, back to the show for a journey into the science of rockets: how expensive is it to travel around our
solar system? What makes rockets with high exhaust velocity better than high-thrust rockets? How hard is it to go to Mars? Also featuring Adam Sliwinski of So Percussion on being an ensemble-in-residence and making music out of cacti, the westerly winds of ancient Tibet, and the life cycles of stars.
