Artemis II astronaut Christina Koch posts video of balance issues after return

Artemis II astronaut Christina Koch posted a video showing wobbliness and an unsteady gait while readapting to Earth's gravity after returning from the mission. Mission medical staff have begun monitoring Koch and started a rehabilitation program to address her balance challenges. Physicians plan to assess her vestibular function, muscle strength, and bone metrics to set recovery timelines and to inform health protocols for future Artemis crews.
