About

C. Zeitlin is a leading researcher in space radiation physics, with a career focused on characterizing the hazardous particle environments encountered during deep-space exploration. His work is critical for understanding the risks to both robotic missions and future human crews traveling beyond low-Earth orbit. A major contribution is his involvement with the Radiation Assessment Detector (RAD) on the Mars Science Laboratory, where he has helped quantify the complex radiation field on the Martian surface. His most-cited paper, "Space radiation measurements during the Artemis I lunar mission" (2024, 30 citations), provides essential data on the radiation environment inside the Orion spacecraft during its journey around the Moon, directly informing NASA's plans for crewed lunar missions. Another highly influential work, "Particle Radiation Sources, Propagation and Interactions in Deep Space, at Earth, the Moon, Mars, and Beyond" (2017, 26 citations), serves as a comprehensive reference for the field. Through studies like "Unfolding the Neutron Flux Spectrum on the Surface of Mars" (2023, 8 citations), Zeitlin continues to refine our understanding of secondary particle production, a key factor in astronaut exposure. His research is foundational for designing shielding and setting safe exposure limits for the next generation of space explorers.
