Lucas Caleb Clarke Murphy • 2026-07-15 • Reviewed by Sofia Lindberg

Few astronauts have captured the public imagination quite like Christina Koch. When she returned to Earth in February 2020 after 328 consecutive days in orbit, she set a record that still stands for the longest single spaceflight by a woman.

Record-breaking spaceflight: 328 days (longest single flight by a woman) ·
Space missions: 1 (ISS Expedition 59/60/61) ·
Current role: Artemis II crew member (lunar flyby) ·
Education: MS in Electrical Engineering, MS in Physics ·
Marital status: Married to Robert Koch

4What’s next
  • Artemis II lunar flyby, no earlier than April 2026
  • First woman to travel beyond low Earth orbit

Six key facts about Christina Koch, drawn from NASA and university records, give a clear picture of her career path.

The pattern in her records reveals a deliberate career built on engineering credentials rather than a research doctorate.

Label Value
Full Name Christina Hammock Koch
Born January 29, 1979, Grand Rapids, Michigan
Education BS Electrical Engineering, MS Electrical Engineering, MS Physics
Space Missions 1 (ISS)
Notable Achievements Longest single spaceflight by a woman, first all-female spacewalk
Current Role Artemis II Mission Specialist
Koch’s choice to pursue dual master’s degrees instead of a PhD kept her on a faster track to astronaut selection — a practical trade-off that paid off.

Does Christina Koch have a child?

  • No. Christina Koch does not have children.

Who is Christina Koch’s husband?

  • She is married to Robert Koch, a software engineer.

The couple has no children, a fact that has been confirmed by NASA’s official biography. The implication: Koch’s personal life remains private, but the absence of children is a deliberate choice that has allowed her to focus on long-duration missions.

Does Christina Koch have a partner?

  • Christina Koch is married to Robert Koch, a software engineer.
  • They have no children.

What this means: her partner is a constant presence in her life, but the couple has chosen a path that prioritizes her demanding career.

Does Christina Koch have a PhD?

  • No. Christina Koch does not hold a PhD.

What is Christina Koch’s educational background?

  • She earned a B.S. in Electrical Engineering from North Carolina State University in 2001.
  • She then completed a second B.S. in Physics and an M.S. in Electrical Engineering in 2002.
  • She also holds an M.S. in Physics.

The trade-off: she chose applied engineering and physics over a doctorate, a path that clearly served her astronaut candidacy.

How many times has Christina Koch been to space?

  • Once. She flew to the International Space Station on March 14, 2019, and returned on February 6, 2020, after 328 days.

What is Christina Koch doing now?

  • She is training for the Artemis II mission, a lunar flyby scheduled for no earlier than April 2026.
  • She served as Mission Specialist I on Artemis II.

The pattern: after a single marathon mission, she is now preparing to become the first woman to travel beyond low Earth orbit, a leap that will define the next phase of her career.

What is Christina Koch doing now?

  • She is training for Artemis II, the first human mission to reach the Moon since 1972.
  • She previously served as branch chief over the Assigned Crew Branch in NASA’s Astronaut Office.

Why this matters: she is not just a passenger on Artemis II; she holds a leadership role and is helping shape the operational side of the mission.

Timeline: From Michigan to the Moon

  • 1979 – Born in Grand Rapids, Michigan
  • 2001–2002 – Earns B.S. in Electrical Engineering, B.S. in Physics, M.S. in Electrical Engineering from NC State
  • 2013 – Selected as NASA astronaut
  • March 2019 – February 2020 – 328-day mission on the ISS, including the first all-female spacewalk
  • April 2023 – Named to Artemis II crew
  • No earlier than April 2026 – Artemis II launch
Her 328-day mission remains the longest single spaceflight by any woman, a record that has stood since 2020 and underscores the endurance required for future lunar missions.

Voices from the Mission

“It’s an incredible privilege and responsibility.”

— Christina Koch, on her Artemis II assignment, as quoted by Space.com (space news outlet)

“Christina Koch is a vital member of the Artemis II crew, bringing her experience from the International Space Station to this historic mission.”

— NASA statement, NASA (U.S. space agency)

For NASA, the Artemis II mission with Koch aboard represents a critical step toward returning humans to the Moon. For young women aspiring to spaceflight, her path—from a small town in Michigan to a seat on the first lunar crew in over 50 years—demonstrates that the journey is possible with the right combination of education, persistence, and timing. Koch’s trajectory mirrors that of other high-achieving individuals like Jannik Sinner and Coco Gauff, who also rose from modest beginnings to the top of their fields through disciplined career choices.

Her 328-day mission aboard the ISS, detailed in Christina Kochs record-breaking spaceflight, set a new standard for women in space exploration.
