Astronaut Christina Koch set a record for women Saturday, logging her 289th day in space at the International Space Station.

Koch, 40, who took off for the space center on March 14, broke Peggy Whitson's world mark for the longest single space flight by a woman, CBS News reported. Whitson spent 288 days in space in 2017-2018, WLOS reported.

Koch, an electrical engineer who graduated from North Carolina State University, told CNN that her record was "a wonderful thing for science."

Koch has made four spacewalks during her time in space, joining fellow astronaut Jessica Meir for history's first all-female spacewalk in October, CBS News reported. Koch plans to team with Meir for two more spacewalks in January, the network reported.

According to NASA's schedule, Koch will remain at the station until February 2020, CNN reported. That will put her a few days shy of NASA's all-time single space flight, set by Scott Kelly in 2016.

The all-time single flight record is 438 days, set in 1995 by cosmonaut Valery Polyakov, CBS News reported.
