Bionanotechnology in Hostile Environments: Speculative Applications for Lunar Medicine in 2050: Population Analysis

Extended analysis and updated findings. Medicine in hostile environments has always advanced on the frontier of technology. Speculative fiction has long imagined the endpoint: medical nanotechnology so advanced that the distinction between physician and pharmacist becomes irrelevant, where programmable molecular machines operate autonomously within the body, repairing damage, delivering drugs, and monitoring physiology at a resolution no macroscale instrument can match.

For lunar medicine, the applications are compelling. Radiation damage — the accumulating DNA strand breaks and oxidative injury from galactic cosmic ray exposure — is currently managed at the population level with dosimetry and early cancer screening. Molecular repair systems that could identify and correct radiation-induced DNA damage in real time would transfo...
