The crew consisted of NASA astronauts Zena Cardman and Mike Finck, Russian cosmonaut Oleg Platonov from Roscosmos, and astronaut Kimiya Yui from the Japan Aerospace Exploration Agency (JAXA). They spent 165 days on the International Space Station.
The reason for the premature return was health issues of one of the astronauts, although their name has not been disclosed. Mention of the illness emerged on January 8, when a planned spacewalk was canceled.
Currently, Russian cosmonauts Sergey Kudy-Sverchkov (who has become the station commander) and Sergey Mikaev, as well as NASA astronaut Christopher Williams, remain on the ISS. The next mission, Crew-12, is expected to arrive at the station in mid-February.
