WASHINGTON, D.C. -- North Carolina State graduate Christina Koch's spaceflight is now set to be a record-breaker.

NASA extended her time on the International Space Station through February 2020. That'll be 11 months after she boarded last month. She's now expected to spend 328 days on board, breaking the record for a woman astronaut and coming just 12 days short of the record for any astronaut.

She will be part of three expeditions – 59, 60 and 61 – during her current first spaceflight. Her mission is planned to be just shy of the longest single spaceflight by a NASA astronaut – 340 days, set by former NASA astronaut Scott Kelly during his one-year mission in 2015-16.

Koch tweeted about her extended mission earlier Wednesday.

The mission schedule currently is as follows:

June 24: Current Expedition 59 crew members Anne McClain of NASA, David Saint-Jacques of the Canadian Space Agency, and Oleg Kononenko of Roscosmos will return to Earth. Koch and fellow NASA astronaut Nick Hague, and Roscosmos cosmonaut Alexey Ovchinin will remain aboard the space station and begin Expedition 60.

July 20: NASA astronaut Andrew Morgan, ESA (European Space Agency) astronaut Luca Parmitano, and Roscosmos cosmonaut Alexander Skvortsov are scheduled to launch to the space station and join Expedition 60, returning the orbiting laboratory's crew complement to six. Parmitano and Skvortsov will return in February 2020 with Koch, leaving Morgan behind for his extended stay.

Sept. 25: NASA astronaut Jessica Meir is scheduled to launch to the station with Roscosmos cosmonaut Oleg Skripochka and United Arab Emirates' Hazzaa Ali Almansoori, a Roscosmos spaceflight participant who will return with Hague and Ovchinin Oct. 3. Meir and Skripochka will return in spring 2020 with Morgan.
