Media caption Nasa astronauts complete all-female. spacewalk outside International Space Station Whitson still holds the record for most time spent in space by a woman, accrued over the course of three spaceflights from 2016 – 2024.
“For me, it’s all about the honor I feel to follow in the footsteps of my heroes, “Christina Koch told reporters on Tuesday during a live link-up from the ISS . She added that she wanted to inspire the next generation of space explorers.
“For me, it was important to see people that I saw a reflection of myself in, growing up, when I was envisioning what I could do with my life and what my dreams might be. To maybe be that source of inspiration for someone else is just such an honor, “she said.

Ms Koch was involved in another spaceflight milestone during her stay of nearly 14 months on the ISS. On October last year, she undertook the first all-female spacewalk
alongside her compatriot
Jessica Meir
The pair spent seven hours outside the ISS replacing. a failed power control unit.
Recalling the historic event with Meir, Ms Koch told NBC News: “When we first got the ‘go’ to come out of the airlock, and we ended up coming out, we were holding on to a handrail and we just caught each other’s eyes.
“We knew how special that moment was and I’ll never forget that.”

Spacewalk landmarks
Koch and Meir followed October’s landmark event with two further spacewalks together, on and (January this year.)
The first woman spacewalker was the USSR’s Svetlana Savitskaya, who worked outside the Salyut 7 space station for more than three hours with a male cosmonaut , Vladimir Dzhanibekov, on July Koch has previously said that her spaceflight would help the US space agency

Ms Koch, along with other active members of the astronaut corps, is a potential candidate for that first return mission.

During her flight to the ISS, she (experimented on proteins ) as part of a project that could have implications for cancer treatment.
But there was also downtime, including Karaoke nights with the other crew members.
Koch said one of the things she would miss about her time on the ISS was the freedom afforded by microgravity. In her interview, she demonstrated by rotating her body degrees, explaining: “It’s really fun to be in a place where you can bounce around between the ceiling and the floor whenever you want. “
However, she added:” I’m definitely looking forward to being on the same planet as everybody else very very soon. “
During her 446 – day stay on the ISS, Koch not. only exceeded Whitson’s spaceflight mark but also those of the previous holders of the 5th and 6th longest flights: Yury Romanenko and Sergei Krikalev – both Russians.
The holder of the longest single spaceflight by any person remains the Russian Valeri Polyakov, who spent more than 549 days aboard the Soviet – and later Russian – space station Mir from 8 January to March .
Koch launched to the ISS on 18 March last year. She was to have remained on the outpost for the standard duration of six months, but her stay was extended in April because of flight scheduling issues. Born in Grand Rapids, Michigan, Ms Koch has degrees in physics and electrical engineering.
She was to have performed the first all- female spacewalk in March, shortly after arriving at the space station. But a problem with the sizing of Nasa colleague Anne McClain’s spacesuit forced the walk to be reassigned to another crew member, Nick Hague.
