From the moment she first learned to surf along the Gulf Coast of Texas 6 years ago, NASA astronaut Christina Koch has spent much of her free time capitalizing on every bump of windswell near her home in Galveston. She’s also ventured abroad to places like New Zealand and Puerto Rico on wave-hunting missions. But in March of last year, Koch set aside her board and wetsuit, committing to a lengthy dry spell for the sake of an entirely different sort of adventure — a mission on the International Space Station that would see her spending 328 days in space, setting a new record for the longest single spaceflight ever completed by a woman in the process.
