Astronaut Christina Koch of the Artemis II mission is a climber. And not just a climber in passing, with rental shoes and little else. She’s a climber to her core, listing “rock and ice climbing” among her hobbies in her NASA profile. The 47-year-old first took up climbing in college at North Carolina State University. She fell in love with everything from the physical challenge of the sport, to the gear, to the trust you place in your partners.
