In the early hours of Feb. 6, physics and engineering alumna and NASA astronaut Christina Koch touched down in Kazakhstan after a record-setting mission to the International Space Station. During her 11 months in orbit, she set the record for the longest female spaceflight and also participated in the first all-female spacewalk.
Her mission, by the numbers:
- 328 days in space
- 139 million miles
- 5,248 orbits of Earth
- 6 spacewalks (42 hours, 15 minutes total)
Look back on some of the highlights of her mission.
