On December 28, 2019, NASA astronaut aboard the International Space Station (ISS) Christina Koch broke the record for “longest spaceflight by a woman”.
Koch has already made history once in her stay aboard the orbital laboratory: in October 2019, she was part of the first-ever all-female spacewalk in history of space exploration.
Koch launched to the International Space Station on March 14, 2019, on Soyuz MS-12, alongside Aleksey Ovchinin and Nick Hague, to join the Expedition 59/60/61 crew. On December 28, 2019, she completed her 289th day aboard the ISS and broke the “longest spaceflight by a woman” record.
The previous record the longest single continuous stay in space for a woman was held by (now retired) NASA astronaut, Peggy Whitson. She spent 289 days in orbit before returning aboard Soyuz MS-04 in June 2017.
The longest spaceflight record
The longest spaceflight record in the history of space exploration belongs to Russia’s Valeri Polyakov, who spent 437 days in space aboard the Space Station Mir between launching on Soyuz TM-18 and landing on TM-20 in 1994-1995.
NASA astronaut Scott Kelly (born February 21, 1964) set the US record by staying in space for 340 consecutive days between 2015 and 2016.
Kelly flew four times to space and commanded the International Space Station on Expeditions 26, 45, and 46. He spent 520 days total in space.
