"You put us in a small spaceship...and we became best friends for life": Artemis II astronaut Christina Koch

Sometimes, the people you work with end up becoming your closest friends—and the Artemis II crew proves it. After three years of training for this historic mission, they launched aboard the Orion spacecraft from Kennedy Space Center on April 1. Over the course of their nearly 10-day journey around the Moon, they experienced every high and low together—coming back not just as a team, but with a bond that’s built to last.
