American astronaut Christina Koch holds several records. In 2019–20 she set the record for longest spaceflight by a woman, having spent 328 days on the International Space Station (ISS). During her time there, she made six spacewalks, including the first three all-woman spacewalks, with Jessica Meir. Then as a mission specialist on Artemis II (April 1–10, 2026), she became the first woman to travel around the Moon. She and the other crew members also set a record for the farthest distance traveled by humans in space: 406,771 km (252,756 miles).
