Artemis II Astronaut Christina Koch Shares Struggle of Adapting to Earth After Moon Mission

Koch said microgravity left her relying on vision after 7 days back on Earth, and a tandem walk with eyes closed proved difficult.

  • NASA astronaut Christina Koch, the first woman to fly around the moon, shared footage on Friday showing her struggle to walk with eyes closed after the Artemis mission splashdown.
  • Microgravity alters how vestibular organs tell the brain about movement, causing astronauts to adapt by relying heavily on visual cues for orientation upon return to Earth.
  • Since their return, the four astronauts—Reid Wiseman, Victor Glover, and Jeremy Hansen—have undergone medical testing of balance and vision, despite completing 30 minutes of resistance training daily during their 10 days in space.
  • Data from the astronauts informs treatment for vertigo and concussions on Earth; Koch explained that "learning about this can help inform how we treat vertigo, concussions and other neuro-vestibular conditions on Earth."
  • Seven days post-splashdown, Koch stated, "Luckily we're already adapting back to gravity at 7 days post-splashdown," while joking, "Guess I'll be waiting a minute to surf again.
