Christina Koch recently returned to Earth after a mission that lasted 328 days, breaking the record for the longest time a woman has spent in space.
This also makes it the second-longest spaceflight ever taken by an American astronaut, with Scott Kelly holding the record for the longest.
This achievement came as NASA is celebrating a 20-year continuous presence on the ISS, 240 miles above Earth.
The NASA Astronaut and her two colleagues landed back on Earth at 4:12 AM (EST) on Thursday 6th Feb after their record-breaking mission.
Their spacecraft successfully landed them on a frozen, remote part of desert in Kazakhstan, 7,000 miles away from the NASA headquarters in Houston, when Koch and most other NASA astronauts live.
The mission lasted 328 days with 5,248 orbits around Earth in total. Six spacewalks took place in which work carried out outside the International Space Station totaled 42 hours and 15 minutes.
Koch, a North Carolina scientist who joined the astronaut corps in 2013, carried out various scientific experiments on board the space station, relating to mustard greens, combustion, kidney diseases, and bio-printing.
The previous record holder was NASA astronaut Peggy Whitson, who spent 288 days on a mission in space in 2017.
