A NASA astronaut has set a new record for time spent in space, and she still has six weeks to go before she returns to Earth.

Christina Koch has surpassed the record for the single longest space mission by a woman as previously established by NASA astronaut Peggy Whitson in 2017. The 40-year-old Expedition 61 flight engineer exceeded Whitson's record of 289 days, 5 hours and 1 minute on Saturday (Dec. 28) at 6:16 p.m. CST (0016 GMT on Dec. 29).

"Having the opportunity to be up here for so long is truly an honor," said Koch during a series of press interviews on Thursday. "Peggy is a heroine of mine and has also been kind enough to mentor me through the years, so it is a reminder to give back and to mentor when I get back."

Koch launched to the space station on March 14 on what was expected to be a typical six-month mission. Then her stay was extended by NASA, in part to collect more data about the effects of long-duration spaceflight. She is now slated to land on Feb. 6, 2020.
