After a record-breaking stint in space, NASA astronaut Christina Koch is back on solid ground.
Koch had six spacewalks over the nearly year-long mission, two of which were all-female journeys with fellow NASA astronaut Jessica Meir. All of Koch’s spacewalks totaled 42 hours and 15 minutes, CNN reported.
While she spent a total of nearly two full days in space over her time on the International Space Station, she broke the record for a woman in space spending 328 days conducting experiments and being a test subject herself. The previous record-holder was Peggy Whitson who was in space for 288 days during a single mission, but she was 12 days short of Scott Kelly’s record of 340 days, the BBC reported.
Koch was part of the Vertebral Strength investigation that takes a look at how bone and muscle loss during extended space missions could be lessened with preventative medicine and exercise, according to CNN.
She also worked on a project growing protein crystals in microgravity. The crystals could help in treating cancer.
Koch arrived on the ISS on March 14, 2019.
