"Undocking of the Soyuz MS-13 spacecraft from Zvezda is scheduled at 10:34 p.m. Central time, 11:34 p.m. Eastern time [Sunday, or 03.34 GMT Monday] with redocking to Poisk scheduled at 10:59 p.m. Central time, 11:59 p.m. Eastern time [Sunday, or 03.59 GMT Monday]," NASA said in a statement.
Earlier, it was reported that the ISS crew would redock the Soyuz MS-13 from the Zvezda module to the Poisk module. This will free up the docking port on the Zvezda module for a repeated attempt to dock the Soyuz MS-14 spacecraft with robot FEDOR inside, which is scheduled for 03.12 GMT on Tuesday.
The Soyuz MS-14 with humanoid robot Skybot F-850, nicknamed FEDOR, onboard was successfully launched into space on Thursday. Earlier on Saturday, the spacecraft, however, failed to dock at the ISS on schedule and started retreating from the station. Later, the spacecraft was pulled to a safe distance from the ISS.
The ISS crew currently comprises Russian cosmonauts Alexey Ovchinin and Alexander Skvortsov, NASA astronauts Christina Koch, Andrew Morgan and Nick Hague, and ESA astronaut Luca Parmitano.
