After almost a year in space, NASA astronaut Christina Koch is coming home. When Koch returns to Earth, she will have lived in space for 328 days, setting the record for the longest single spaceflight by a woman. On Dec. 28, 2019, she surpassed the previous record of 288 days held by NASA astronaut Peggy Whitson. Her extended mission will provide researchers the opportunity to observe effects of long-duration spaceflight on a woman as the agency plans to return to the Moon under the Artemis program and prepare for human exploration at Mars. During this record-setting mission, Koch spent many of her hours on science activities aboard the space station and wore many hats: farmer, biologist, physicist, engineer, test subject and many more.
Here is a look back at Koch’s efforts as she conducted research in microgravity on Mizuna mustard greens, combustion, bioprinting and kidney diseases, among others.
