Space Travel

The article frames space travel as a biological resilience problem as well as an engineering problem. Short suborbital flights are treated as biologically different from long orbital or Mars missions. The article does not provide a validated astronaut preparation protocol for long-duration space exposure. Ketosis is mentioned as a possible DNA-protective space strategy but not as an established standard. The proposed spaceflight response combines baseline testing, pre-flight optimization, DNA-repair support, inflammation control, and possible metabolic strategies. Space exposes humans to stressors including radiation, electromagnetic exposure, DNA damage, altered gravity, and bone density loss.
