About

Jussi Lehti is a leading researcher in space radiation physics, with a focus on characterizing the deep-space radiation environment to safeguard future human exploration. His most prominent work involves the first comprehensive measurements of space radiation during the Artemis I lunar mission, a landmark study that provides critical data on galactic cosmic rays and trapped particles beyond low Earth orbit. This 2024 paper, already garnering 30 citations, directly addresses the primary hazards of long-duration spaceflight—including cancer, cataracts, and degenerative tissue risks—by quantifying acute and chronic exposure levels. Lehti’s contributions are pivotal for designing shielding and risk mitigation strategies for upcoming crewed lunar and Mars missions. His research bridges fundamental radiation physics and practical astronaut safety, earning recognition from both space agencies and the planetary science community. By delivering empirical evidence from humanity’s return to the Moon, Lehti has established himself as a key voice in the next era of deep-space human exploration, where his measurements will inform everything from spacecraft design to mission duration limits.
