Mars Colonization Realities

Elon Musk's Mars timeline remains ambitious, but the biological challenges are stark. Radiation exposure during transit exceeds lifetime limits. Martian dust contains toxic perchlorates. Low gravity may cause irreversible bone density loss. Solutions like artificial magnetic fields and underground habitats exist theoretically, but testing requires decades. The first Martians won't be settlers—they'll be scientists accepting extreme risks. Permanent colonization remains centuries away, not years, regardless of rocket capability.
