After spending 328 days in space on the International Space Station, NASA astronaut Christina Koch had to relearn basic movements like walking when she returned to Earth.
Her body had adapted to zero gravity, so muscles and balance needed time to readjust to Earth’s gravity. In these powerful photos, she’s seen training and slowly regaining strength with the help of her team.
Christina is set to make history again as part of the Artemis II mission — the first crewed flight around the Moon in over 50 years. Her journey highlights the incredible physical and mental challenges of space exploration.
This is a powerful reminder of what astronauts sacrifice for science and discovery.
