Astronaut activity

Koch was selected to be a member of NASA Astronaut Group 21 on June 17, 2013.

On March 15, 2019, she reached the ISS as a member of the Soyuz MS-12 crew. Originally, it was planned that she would take part as a flight engineer in the long-term missions Expedition 59 and Expedition 60 , which corresponds to a stay of about half a year. Due to delays in the completion of the new US spaceships Crew Dragon and CST-100 Starliner , their planned stay was extended to Expedition 61 , which was also extended. This corresponds to a total length of stay of eleven months. On February 6, 2020, Koch returned to Earth with Soyuz MS-13 .

During her stay on the ISS, Koch undertook several space missions for maintenance work on the station's power supply. She completed her first space exit with Nick Hague on March 22, 2019, the second with Andrew Morgan on October 6. The two missions lasted around seven hours each. A third on October 18, 2019 together with Jessica Meir attracted a lot of attention, as it was the first time that an all-female team was on the field. The mission lasted seven hours and 17 minutes, including a brief live television broadcast of US President Donald Trump and Vice President Mike Pence .

In December 2019, Koch set the previous world record for a woman to stay in space continuously and subsequently surpassed it with 328 days. The US astronaut Peggy Whitson had previously kept him on the ISS for 289 days (2016/17). Koch also achieved the second longest stay of a US astronaut in space, after Scott Kelly with 340 days.


Christina Hammock Koch is married and lives in Texas with her husband Robert Koch . Her hobbies include climbing, sailing, yoga , as well as photography and traveling.
