NASA ASTRONAUT CHRISTINA KOCH RECOUNTS RECORD-BREAKING 328-DAY SPACE MISSION: 'BOREDOM WAS NOT A PROBLEM AT ALL

Koch’s nearly 11 months in orbit set a record for the longest spaceflight by a woman.

Earlier this week, Koch told Fox News’ Bill Hemmer that boredom was never a problem during her stint on the ISS.

“I wish I had enough time on there to get bored, but not all,” she explained, during her first live TV interview since returning to Earth on Thursday.

When not busy performing experiments, Koch explained that she “soaked up the unique atmosphere” of the floating space lab by taking pictures and spending time with her crewmates. “Boredom was not a problem at all,” she added.

The mission gave researchers the opportunity to observe the effects of long-duration spaceflight on a woman. The study is important because NASA plans to return to the moon under the Artemis program and prepare for the human exploration of Mars.

“It helped me see that all humans are inherently the same,” she said.

In October 2019, Koch and fellow NASA astronaut Jessica Meir made history with the first all-female spacewalk.
