Artemis II astronaut Christina Koch is struggling to walk and regain balance after returning from her historic mission around the Moon.
Koch shared a video showing her difficulty with a tandem walk, explaining that microgravity disrupts the body’s vestibular system, requiring adaptation upon return.
Her experience highlights the physical challenges astronauts face after spaceflight and offers insights for treating balance disorders on Earth.

Artemis II Splashdown Highlights Vestibular System Breakdown and Implications for Lunar Exploration
Overview
The Artemis II mission, which exposed its crew to microgravity for 10 days, safely splashed down in the Pacific Ocean on April 10, 2026. Upon return, astronauts, especially Christina Koch, faced immediate balance and spatial orientation challenges caused by vestibular system disruption from prolonged weightlessness. Medical teams quickly began comprehensive testing, while Koch started a targeted rehabilitation program that led to significant balance improvement within a week. These findings highlight risks posed by the Moon's reduced gravity for future Artemis missions, prompting NASA to develop countermeasures like in-flight exercise and artificial gravity. The mission’s data also advances treatments for Earth-based vestibular disorders, bridging space medicine and terrestrial healthcare.
