NASA astronaut Tracy C. Dyson and Roscosmos cosmonauts Nikolai Chub and Oleg Kononenko will close the hatch between the Soyuz MS-25 spacecraft and the International Space Station at 1:05 a.m. EDT Monday, Sept. 23.
The spacecraft will undock from the orbiting laboratory’s Prichal module at 4:37 a.m. to begin the journey back to Earth, heading for a parachute-assisted landing at 8 a.m. (5 p.m. Kazakhstan time) on the steppe of Kazakhstan, southeast of the town of Dzhezkazgan.
NASA will provide live undocking coverage at 4 a.m. on NASA+ and the agency’s website.
Spanning 184 days in space, Dyson’s mission includes covering 2,944 orbits of the Earth and a journey of 78 million miles. The Soyuz MS-25 spacecraft launched March 23, and arrived at the station March 25, with Dyson, Roscosmos cosmonaut Oleg Novitskiy, and spaceflight participant Marina Vasilevskaya of Belarus. Novitskiy and Vasilevskaya were aboard the station for 12 days before returning home with NASA astronaut Loral O’Hara on April 6.
Kononenko and Chub, who launched with O’Hara to the station on the Soyuz MS-24 spacecraft last September, will return after 374 days in space and a trip of 158.6 million miles, spanning 5,984 orbits.
Dyson spent her fourth spaceflight aboard the station as an Expedition 70 and 71 flight engineer, and departs with Kononenko, completing his fifth flight into space and accruing an all-time record 1,111 days in orbit, and Chub, who completed his first spaceflight.
