- Christina Koch made the return trip from the International Space Station (ISS) , along with ESA astronaut Luca Parmitano and Russian cosmonaut Alexander Skvortsov.
- Koch’s trip was significant because it set a record, officially making her the U.S. astronaut with the second-longest stay in space with 328 consecutive days at the Station. She’s second only to Scott Kelley, who spent 340 days in space, and she’s officially the woman with the longest stay in space worldwide, passing fellow U.S. astronaut Peggy Whitson’s record of 289 days.
