"It felt great": Artemis II astronaut Christina Koch on post-flight moonwalk simulations

After returning to Earth, Artemis II astronaut Christina Koch jumped straight into intense, suit-up simulations to help refine future Artemis moonwalks. The idea? Train while the body isn’t fully readjusted—just like astronauts would experience right after landing on the Moon. "We didn’t walk on the Moon until we got back to Earth. To understand how to optimize lunar surface spacewalks on future Artemis missions, we do simulated runs as soon as we are back. Spoiler alert: It felt great," she wrote in the caption.
