In brief
The Artemis II mission presents unprecedented physiological challenges as astronauts spend ten days in microgravity.

Understanding how human physiology responds to prolonged space exposure remains crucial for future long-duration missions and deep space exploration, as our bodies evolved for Earth's gravitational environment.
