The crew included NASA astronauts Zena Cardman and Mike Fincke, Roscosmos cosmonaut Oleg Platonov, and JAXA astronaut Kimiya Yui. They spent 165 days aboard the ISS.
The reason for the emergency return was the deterioration of health of one of the mission participants, whose identity has not been disclosed. Information about health issues emerged on January 8, when a scheduled spacewalk was canceled.
Currently, Russian cosmonauts Sergey Kud-Sverchkov (the new commander) and Sergey Mikaev, as well as NASA astronaut Christopher Williams, remain on the ISS. The next Crew-12 mission is expected to arrive at the station in mid-February.
