Christina Hammock Koch is an American astronaut who was selected as a member of NASA's astronaut corps in 2013. She was born on January 29, 1979, in Michigan, USA, and grew up in Jacksonville, North Carolina.

Koch graduated from North Carolina State University with a Bachelor of Science in Electrical Engineering and Physics in 2001. She then worked for several years as an electrical engineer at NASA's Goddard Space Flight Center and the Johns Hopkins University Applied Physics Laboratory.

In 2012, Koch was selected as one of eight members of NASA's 21st astronaut class, which was the first to include equal numbers of men and women. After completing two years of training, she was assigned to Expedition 59/60, which launched to the International Space Station (ISS) in March 2019.

Koch's contributions to space exploration and her advocacy for women in STEM have made her a role model for aspiring astronauts and scientists around the world.

Koch's contributions to space exploration are numerous, including the following:

1. Longest Single Spaceflight by a Woman: Christina Koch holds the record for the longest single spaceflight by a woman, spending 328 days in space on the International Space Station (ISS). She surpassed the previous record of 288 days set by Peggy Whitson in 2017.
2. Conducted Spacewalks: During her time on the ISS, Koch conducted six spacewalks, totaling 42 hours and 15 minutes. Her spacewalks included the first all-female spacewalk with astronaut Jessica Meir in October 2019.
3. Scientific Research: Koch conducted several scientific experiments during her time on the ISS, including research on plant growth in microgravity and the effects of long-duration spaceflight on the human body.
4. Leadership: Koch served as the Crew Support Officer for the Expedition 56 crew, responsible for coordinating logistics and communication between the ISS and ground support teams.
