- Artemis II's primary scientific focus is on radiation measurements to enable safe human exploration beyond Earth's magnetic field.
- Radiation hazards include trapped particles in Van Allen belts, solar particle events, and chronic galactic cosmic rays.
- Radiation assessment considers factors like dose rate, particle type, shielding, and spacecraft orientation.
- Artemis II uses multiple tools: cabin monitors, crew-worn dosimeters, upgraded detectors, and biological experiments.
- The mission aims to map radiation geometry with crew onboard, helping decide sheltering strategies during solar events.
- AVATAR experiment uses organ chips from astronauts' bone marrow cells to study radiation's impact on immune function.
- NASA collects immune biomarkers via saliva and blood samples, tracking physiological responses like sleep and cognition.
- Radiation interacts with other mission stressors like microgravity, confinement, and workload, complicating biological effects.
