In this Climate Chat episode, host Dan Miller interviews Planetary Sunshade Institute's Board Member and former Executive Director, Ross Centers, on the science, risks, and reality of using giant space-based sunshades located between the Sun and the Earth to reduce global warming.
Ross Centers is an American planetary geologist, space entrepreneur, and climate advocate. He is the Co-Founder and CEO of Ethos Space, a lunar infrastructure startup. Based in Los Angeles, California, Centers has positioned himself at the intersection of commercial space resource utilization (SRU) and space-based climate mitigation technologies. By leveraging a deep technical background in space architecture and resources, his career focuses on establishing the physical infrastructure required to sustain an off-world economy while simultaneously building tools to stabilize Earth's climate. Centers developed his expertise in aerospace and geology at the Colorado School of Mines, where he earned a Master’s degree in Space Resources.
