A NASA astronaut will spend nearly a year at the International Space Station, setting a record for women. Station astronaut Christina Koch will remain on board for about 11 months until February — approaching but not quite breaking Scott Kelly’s 340-day US record. She tweeted Wednesday: “One month down. Ten to go.” Koch knew before launching last month that her flight might stretch into 2020 and sought advice from Kelly as well as retired astronaut Peggy Whitson, the current record-holder for female space fliers. Koch will break Whitson’s 288-day record for the longest single spaceflight by a woman at the end of December.
