The American astronaut’s time on the International Space Station is said to be the longest continuous spaceflight by a female astronaut.
She return to earth on January 6, 2020, having blasted off on 12 March last year.
Her voyage saw her make 5,248 orbits of the Earth, witnessing 16 sunrises and sunsets every day, and travel 223m km, according to The Guardian newspaper.
While in space, Koch recounted her fond memories at the University of Ghana, saying it was a positive, life-changing, perspective-deepening experience.
“Seeing the beauty of Ghana from space reminds me of the amazing people I met there and how in exploring the world, we learn about ourselves,” he added.
The US astronaut took a semester to study in Ghana while pursuing a Bachelor of Science degree in Electrical Engineering and Physics at North Carolina State University.
Koch is a NASA astronaut of the class of 2013. She was selected as one of the eight members of the 21st NASA astronaut class.
