U.S. astronaut Christina Koch, who led the first all-female spacewalk in 2019, was due to return to Earth on Thursday.
Koch is returning after completing a record stay aboard the International Space Station.
Koch was scheduled to climb into a Russian Soyuz capsule and depart at 9:30 p.m.
On Wednesday.
If all goes according to plan, the capsule will parachute to a safe landing in Dzhezkazgan, Kazakhstan.
Koch’s 328-day mission broke the record for the longest continuous stay in space by a woman.
