Christina Koch Begins Earthbound Recovery From Artemis II Vestibular Changes
Christina Koch says her vestibular system isn’t functioning normally after Artemis II’s 10-day lunar flyby and is undergoing physical therapy to readjust to Earth's gravity; she explains that the brain relies on vision and eyes to orient itself after microgravity, with a tandem walk with eyes closed being particularly challenging, and notes recovery is underway about a week after splashdown as NASA researchers study neuro-vestibular effects from extended microgravity missions.
