NASA astronaut Christina Koch set a spaceflight record over the weekend. Koch eclipsed the record for the longest single spaceflight by a woman on Saturday with her 289th day in space. Koch is scheduled to spend 328 days in space, returning in early February. Koch broke the record that had been set by Peggy Whitson, who still has the record for cumulative time in space by a woman at nearly 666 days.
