Four astronauts on the Crew-11 mission will depart the International Space Station as early as Wednesday on NASA's 1st medical evacuation.

With Crew-11 set to depart shortly, command of the ISS will fall to Russian cosmonaut Sergey Kud-Sverchkov. He'll remain on the station with fellow Soyuz travellers, NASA astronaut Chris Williams and Roscosmos cosmonaut Sergei Mikaev. They will be the only crew aboard the station until SpaceX Crew-12 launches in February.
