Video Shows NASA Astronaut Struggling to Walk After Journey Around the Moon

NASA astronaut Christina Koch posted a post-splashdown video showing temporary trouble walking with her eyes closed.

NASA says the effect is normal after microgravity, as the inner ear and brain readjust to Earth’s gravity.

The clip underscores how spaceflight can disrupt balance and how astronauts recover after landing.

It also offers insight that may help researchers better understand dizziness, vertigo, and other vestibular disorders on Earth.
