NASA astronaut Christina Koch is returning to Earth later this week after a record-setting mission onboard the International Space Station (ISS). Koch launched to the ISS in March 2019, and her extended time on station set a record for the longest single spaceflight by a woman. Koch also conducted the first all-woman spacewalk with fellow ISS crew member NASA astronaut Jessica Meir.
During her time in orbit, Koch worked on an immense amount of research sponsored by the ISS U.S. National Laboratory—ranging from the life and physical sciences to materials science, remote sensing, technology development, and education. Below highlights some of the many ISS National Lab investigations Koch worked on while onboard the ISS.
