On Thursday morning, Christina Koch and two colleagues touched down on Earth after almost a year in space. This marks the longest single spaceflight by a woman. She also has had the second-longest stay in space in the US, with 328 days. Koch orbited the Earth 5,248 times, traveling 139 million miles. Her trip will provide researchers information on how space travel affects women in the long run, eventually ending with another trip to the moon and humans walking on Mars. On October 18th, she and Jessica Meir, another person on the flight with her, completed the first all-female space walk. Congratulations to them on breaking so many records!
