Christina Koch: Biography, Record-Breaking Flight & Artemis II

Christina Koch’s name keeps surfacing in headlines about space exploration because she set the record for the longest single spaceflight by a woman, spent 328 consecutive days aboard the International Space Station, and is now preparing to circle the Moon on Artemis II. This article assembles verified facts about her biography, record-breaking career, personal life, and the practical realities of astronaut pay and life in space.

NASA astronaut since 2013 · Longest single spaceflight by a woman 328 days · Spacewalks performed 6 · Artemis II mission role Mission Specialist · Total hours in space over 7,800

Eight key details capture the core of Christina Koch’s journey and credentials.

These credentials span her full career arc from education through record-setting ISS expedition to her next mission around the Moon.

Does Christina Koch have a child?

Christina Koch’s family status

• Christina Koch does not have children. All credible sources — including her NASA bio (official astronaut page) and public social media — make no mention of children, and in interviews she has not stated having any.

Does Christina Koch have a partner?

• Yes. Christina Koch is married to Robert Koch. The couple lives in Texas. (NASA (official astronaut bio))

The implication: Koch has chosen to focus on her demanding career during peak training years. No public indication of future family plans exists.

How much money do NASA astronauts get paid?

NASA astronaut salary range

• NASA astronauts are paid on the U.S. General Schedule (GS) scale. A Yahoo Finance report (business news outlet) states most NASA astronauts earn roughly $150,000 per year. The top of the GS-15 scale reaches about $152,000, noted in a Fortune repost on LinkedIn (business media), though this is secondary reporting rather than official NASA salary data.

Artemis II astronaut compensation

• Artemis II astronauts receive standard NASA salary plus per diem during training and mission. Yahoo Finance (business news outlet) reported in 2026 that crew members would earn about $152,000 per year while on the mission roster. A Reddit discussion (social forum) claimed similar figures, but that source carries low confidence.

The catch: a comfortable but not spectacular salary for a job that involves life-changing risk and years of training.

What was Christina Koch famous for?

Record-breaking spaceflight

• Koch set the record for the longest single spaceflight by a woman: 328 days. The Astronaut Scholarship Foundation (educational nonprofit) adds that she completed 5,248 orbits of Earth during that mission.

First all-female spacewalk

• On October 18, 2019, Koch and fellow NASA astronaut Jessica Meir performed the first all-female spacewalk. NASA (official astronaut bio) confirms the event.

Artemis II mission

• In April 2023, Koch was assigned as mission specialist for Artemis II, the first crewed lunar flyby mission since 1972. NASA’s Artemis crew page (official mission page) lists her alongside Victor Glover, Reid Wiseman, and Jeremy Hansen.

The pattern: Koch’s achievements have reshaped public expectations for women in space exploration, moving from participation to record-setting leadership.

How do female astronauts menstruate?

Menstruation in microgravity

• No medical reason prevents menstruation in space. According to NASA’s health guidance (official space agency), female astronauts can use birth control pills to suppress menstruation if they choose, or manage periods normally with tampons and pads.

Options for female astronauts

• Menstrual products are available on the ISS. Many astronauts opt to suppress their period to reduce waste and simplify hygiene in microgravity. NASA (official astronaut bio) notes that Koch used birth control to skip periods during her 328-day mission.

The implication: spaceflight does not require sacrificing reproductive health — it’s a matter of personal choice and mission practicality.

Where does astronaut urine go?

Urine collection on the ISS

• Astronauts use a funnel-and-hose system connected to the toilet. NASA’s ISS operations documentation (official space agency) explains the design.

Water recycling system

• The Water Recovery System (WRS) on the ISS recycles urine into drinking water. NASA (official space agency) states the system recovers about 90% of water from urine.

The pattern: every drop is reused — a critical capability for long-duration missions to the Moon and Mars.

The timeline reveals a steady progression from engineering degrees to a record-setting ISS stay and onward to lunar exploration.

Clarity: What we know vs what’s uncertain

Voices on Christina Koch

Christina Koch is a NASA astronaut and engineer who has spent 328 days in space — the longest single spaceflight by a woman.

NASA (official astronaut bio)

She holds the record for the longest single spaceflight by a woman at 328 days and completed 5,248 orbits of Earth during that mission.

For anyone dreaming of a career in space, Christina Koch’s path proves that engineering expertise, perseverance, and a willingness to push boundaries can lead to the Moon and beyond. The trade-off: the mental and physical demands of long-duration spaceflight remain significant, and the paycheck, while comfortable, is modest by celebrity standards. For aspiring astronauts and space fans, the decision to invest years of training is clear: the experience of exploring the cosmos is unmatched, but it comes with real personal sacrifices.
