A US astronaut set a record Saturday for the longest single spaceflight by a woman, breaking the old mark of 288 days with about two months left in her mission. Christina Koch, a 40-year-old electrical engineer from Livingston, Montana, arrived at the International Space Station on March 14. She broke the record set by former space station commander Peggy Whitson in 2016-2017.
