Christina Koch Christina Koch is an American electrical engineer, NASA astronaut, and researcher known for long-duration missions aboard the International Space Station and for setting records in extravehicular activity. Her career spans work in electrical engineering, atmospheric research, and human spaceflight, with roles at institutions including Draper Laboratory, Goddard Space Flight Center, and the Johnson Space Center. Koch's missions contributed to science across disciplines such as Earth observation, space biology, and space medicine.

Early life and education

Koch was born in Grand Rapids, Michigan and raised in Jackson, Michigan and Portage, Michigan. She attended Portage Central High School before earning a Bachelor of Science in Electrical Engineering from North Carolina State University and a Master of Science in Electrical Engineering from University of Alaska Fairbanks. During her studies she participated in research associated with NOAA and the United States Antarctic Program, leading to involvement with polar science programs at McMurdo Station and South Pole Station.

Engineering and NASA career

Koch began her professional career as an electrical engineer at Draper Laboratory and later joined NASA Goddard Space Flight Center where she worked on Earth science missions and payloads. She contributed to projects involving satellite instrumentation, remote sensing, and systems engineering for platforms such as Landsat and other observational programs. Selected as part of a NASA astronaut candidate group, she trained at Johnson Space Center in astronaut operations, payload integration, and Soyuz and Commercial Crew Program familiarization. Her duties included roles in mission planning, robotics, and extravehicular activity procedures for expeditions to the International Space Station.

Spaceflights and records

Koch flew to the International Space Station as part of Expedition crews where she logged an extended-duration mission aboard the station, setting a record for the longest single spaceflight by a woman. While on station she participated in multiple spacewalks (extravehicular activities), including the first all-female spacewalk alongside NASA colleague Jessica Meir. During her tenure she supported robotic operations using the Canadarm2 and contributed to operations coordinating visiting vehicles such as SpaceX Dragon and Northrop Grumman Cygnus. Her mission assignments involved international cooperation with partners including Roscosmos, European Space Agency, Japan Aerospace Exploration Agency, and Canadian Space Agency personnel on board the station.

Research and scientific contributions

On station Koch conducted experiments in areas including human physiology, plant biology, and materials science, supporting investigations from institutions such as Columbia University, Massachusetts Institute of Technology, and Stanford University. She worked on studies of bone density, muscle atrophy, and fluid shifts relevant to space medicine and long-duration exploration, enabling data useful to programs planning missions to Mars and Moon. Her work with Earth-observing instruments contributed to monitoring polar processes, atmospheric composition, and natural hazards, linking to research centers like NOAA and NASA Goddard Space Flight Center. Koch also supported technology demonstrations in life support and habitat systems relevant to Artemis and future deep-space missions.

Personal life and advocacy

Koch has spoken publicly about the importance of diversity, inclusion, and STEM outreach, collaborating with organizations such as Society of Women Engineers, Girl Scouts of the USA, and educational programs at Smithsonian Institution venues and National Air and Space Museum events. She has highlighted issues related to polar research through engagements with National Science Foundation programs and promoted awareness of climate and Earth systems via partnerships with NASA Earth Science. Koch maintains private pursuits in outdoor activities common among polar explorers and advocates for increased representation of women and underrepresented groups in aerospace careers and scientific fields.
