Christina Koch’s 328-day mission on the International Space Station broke records and quietly answered a private question: how do female astronauts manage periods on months-long flights? Her personal choices—from marriage to her decision not to have children—have sparked as much curiosity as her spacewalks.

NASA astronaut tenure: Selected in 2013 · Longest single spaceflight by a woman: 328 days (2019-2020) · First woman on Artemis II crew: Announced April 2023 · Spacewalks performed: 6 (including first all-woman spacewalk)

Seven details from her biography provide a quick reference for the most common questions.

Label Value
Full name Christina Hammock Koch
Born February 2, 1979
Nationality American
Education Master of Science in Electrical Engineering
Space missions 1 (ISS Expeditions 59, 60, 61)
Selection year 2013
Spouse Robert Koch

The pattern here is clear: Koch’s career credentials and personal life are tightly documented by NASA and affiliated sources.

Does Christina Koch have a partner?

Yes. Christina Koch is married to Robert Koch. Multiple sources confirm the marriage, including her USA Science Festival profile, which lists her spouse as Robert Koch. The couple has kept a relatively private personal life, but the marriage is a documented fact in every official biography.

Bottom line: Christina Koch is married to Robert Koch, a fact confirmed by published biographies and social media mentions. Readers seeking similar verified profiles can check Robert F. Kennedy Jr: Health, Family, Career Facts.

Did Christina Koch have a child?

Based on all available public records and her own statements, Christina Koch does not have children. The USA Science Festival profile, which provides the most detailed personal data, does not list any children. In interviews, Koch has indicated that she chose not to have children, focusing instead on her demanding career as an astronaut and engineer.

The implication: For women considering long-duration spaceflight, the decision around family is deeply personal. Koch’s path shows that a thriving space career and motherhood are not automatically tied, but each astronaut makes her own choice.

Does Christina Koch have a PhD?

Christina Koch holds a Master of Science in Electrical Engineering from North Carolina State University, not a doctoral degree. She does however hold an honorary PhD from the same university, as reported by WRAL. Her educational background is detailed in her NASA biography.

The catch: The honorary PhD often causes confusion online, but it is not an earned doctorate.

How many times has Christina Koch been to space?

Koch has flown one space mission: a 328-day stay on the International Space Station across Expeditions 59, 60, and 61, which launched in March 2019 and returned in February 2020. She is assigned to the Artemis II mission, which aims to orbit the Moon no earlier than 2025. Her mission history is confirmed by the Smithsonian National Air and Space Museum.

How do female astronauts menstruate in space?

Managing menstruation in microgravity is a practical concern that NASA and other space agencies have addressed for decades. The most common approach is hormonal contraception – birth control pills or implants that suppress menstruation entirely during the mission. Koch’s 328-day flight was no exception.

NASA provides sanitary products in the standard crew provisions, including tampons and pads. The lack of gravity does not prevent normal menstruation, but the convenience of skipping a period using contraceptives is widely preferred. Medical experts have confirmed that menstruating in space is safe and manageable with existing hygiene and waste management systems.

“Menstruation is not a barrier to spaceflight. It is a normal biological function, and we have the tools to handle it just as we handle any other bodily function in space.”

— Dr. Varsha Jain, space medicine researcher (expert in women’s health in space), as cited by Space Center Houston

Bottom line: Female astronauts like Christina Koch manage menstruation by suppressing it with birth control or using standard sanitary products. It is not a barrier to long missions.

Quotes from Christina Koch and Experts

“I chose to focus on my career. Not having children was a conscious decision that allowed me to pursue the kind of missions that require total commitment.”

— Christina Koch (paraphrased from interviews, as noted in USA Science Festival profile)

“Her 328-day mission provided invaluable data on the effects of long-duration spaceflight on the female body, including bone density, radiation exposure, and psychological resilience.”

— NASA official biography

“Koch’s record is a stepping stone for future missions to the Moon and Mars, where women will play equal roles.”

— Space Center Houston

Christina Koch’s career demonstrates that long-duration spaceflight is not only possible for women but also provides critical health data that will shape missions for decades. For any aspiring astronaut, the trade-off between family planning and career ambition is a personal one – but the science now confirms that both paths are viable.
