Future challenges for astrocytology, astroembryology and astrohistology

Human settlement in space brings with it interconnected biomedical challenges stemming from gravity, radiation, and temporal variability. Microgravity alters cellular processes, while cosmic radiation accelerates DNA damage. Furthermore, the absence of Earthly zeitgebers disrupts circadian rhythms and necessitates chronobiological adaptations. To overcome these challenges, interdisciplinary collaboration across physics, medicine, and molecular biology is essential to develop preventive strategies and ensure human health, survival, and evolution beyond Earth's boundaries.
