Astronaut Christina Koch just broke the world record for the longest time spent in space by a woman. Here are 4 breathtaking photos of Earth she captured from 250 miles above the planet.

Christina Koch launched into space for her first mission on March 14, 2019. She was a part of Expeditions 59-60-61 during her stay on the International Space Station.

While in space, Koch captured breathtaking photos of Earth's landscapes and oceans from 250 miles above.

Koch completed 5,248 orbits of the Earth during a 139 million mile journey. Her mission paves the way for research into the effects of long-duration spaceflights on women.

Koch's involvement supports NASA's goal for future human landings on the Moon, and eventually Mars.
