NASA astronaut will break the record for longest spaceflight by a woman

NASA astronaut Christina Koch will soon set the record for the longest spaceflight by a woman. The space agency set a new schedule and assignments for crew on the International Space Station this week, revealing Koch’s mission has been extended to a total of 11 months. Koch arrived at ISS on March 14 and is now expected to remain in orbit until February 2020. This will bring her total time away from Earth to a number just shy of the all-time record for the longest single spaceflight – 340 days, set by former NASA astronaut Scott Kelly – and eclipse the 288-day milestone set by Peggy Whitson in 2016-17.
