NASA astronaut Christina Koch is going to set record for longest single spaceflight by a woman.
About:
NASA astronaut Christina Koch is going to have her mission on the International Space Station (ISS) extended to 328 days. Koch arrived at the space station on March 14 and now is scheduled to remain in orbit until February 2020.
Current record holders:
This would set a record for the longest single spaceflight by a woman by breaking the record of 288 days set by former NASA astronaut Peggy Whitson in 2016-17.
The longest single spaceflight by a NASA astronaut is 340 days, set by former NASA astronaut Scott Kelly during his one-year mission in 2015-16.
Significance: Her extended mission will help scientists gather additional data about the effects of long-duration human spaceflight beyond those of the normal six-month station expedition. Such research is essential to support future missions to the Moon and Mars.
