Hazards · RIDGE

Radiation

GCR, solar particle events and trapped belts beyond Earth's protective magnetosphere.

Isolation & Confinement

Behavioral health, sleep, team dynamics in small, closed crews.

Distance from Earth

Medical autonomy, communication delay, no rapid evacuation.

Gravity Fields

Microgravity, partial gravity, and the transitions between them.

Hostile/Closed Environment

Atmosphere & CO₂, toxicology, microbiology, noise, dust.
