She landed in Kazakhstan on February 6 with two colleagues aboard a Russian capsule. According to the Huffington Post, her time in space was just 12 days shy of the American spaceflight record, held by astronaut Scott Kelly.
"I didn't necessarily know what this mission was going to turn into when I launched", Koch told ABC News' senior transportation correspondent David Kerley in an interview from the space station last month. This makes her unprecedented mission the second-longest spaceflight in NASA history.More news: Proud father Dwayne Wade remembers the moment his daughter announced her transition
