Artemis II and the invisible hazard on the way to the Moon

6 hours ago

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.
