How to prepare humans for space travel
summary
Microgravity shifts fluid to the head causing puffy faces and raised intracranial pressure that flattens the eye, bone and muscle loss that current countermeasures largely contain with a T2 treadmill and ARED 550-pound resistance, and severe sensory‑motor breakdown: tandem‑walk failures, vomiting and blackouts on gravity transitions. Field tests reach crewmembers within 30 minutes using a lab‑in‑a‑backpack 70 lb, VR training (four days of 20‑minute sessions) cuts disorientation long‑term, and proposed fixes range from exoskeletons to short‑radius centrifuges.
