NASA Astronaut Christina Koch—Space Station Scientist & Spacewalker

NASA Astronaut Christina Koch—Space Station Scientist & Spacewalker


Six years before her Artemis II Moon Mission, NASA astronaut, scientist, mission specialist, flight engineer, and spacewalker Christina Koch spent almost a year in space on International Space Station Expeditions 59-61, before coming home. 

When Koch returned to Earth after her long-duration human spaceflight mission, she had lived in space for 328 days, setting the record for the longest single spaceflight by a woman. During this time, Koch spent many of her hours on science activities aboard the International Space Station and wore many hats—farmer, biologist, physicist, engineer, test subject and many more. 

Christina also participated in the first all-female spacewalk with fellow NASA astronaut Jessica Meir, currently serving aboard the International Space Station on Expedition 74.

Artemis II mission specialist and NASA astronaut Christina Koch joined NASA astronauts Reid Wiseman, Victor Glover, and Canadian Space Agency astronaut Jeremy Hansen on a nearly 10-day lunar flyby mission, surpassing the Apollo 13 record for farthest crewed spaceflight and observing the lunar surface like never before, capturing iconic views.
