Astronaut Christina Koch will soon break the record for longest single spaceflight by a woman, NASA announced Wednesday. Koch will beat out former NASA astronaut Peggy Whitson, who was in space for 288 days two years ago. Koch, who arrived at the space station in March, will stay on mission until February 2020, NASA writes. The 328-day orbit will allow researchers to study the effect of long-term spaceflights on the body. Last month, Koch and Anne McClain were among NASA's top picks for its first female-led spacewalk, though the trip was later canceled amid spacesuit sizing issues.
