Christina Koch Says She's Recovering From Major Physical Change After Artemis II

Christina Koch and the rest of the four-person Artemis II crew returned to Earth this past Friday, splashing down off the coast of San Diego after their historic 10-day lunar flyby mission.

Now, Koch is getting readjusted to life on Earth.

On Friday, Koch posted a video of herself going through physical therapy. The NASA astronaut explained that her "vestibular organs" are not working correctly due to her 10-day experience in microgravity.

"Guess I’ll be waiting a minute to surf again," Koch wrote in an Instagram post.
