Expedition 58

Expedition 58 was a three-person International Space Station increment commanded by Roscosmos cosmonaut Oleg Kononenko, with NASA astronaut Anne McClain and Canadian Space Agency astronaut David Saint-Jacques serving as flight engineers. The increment began on December 20, 2018, after Soyuz MS-09 departed with the Expedition 57 crew, leaving the Soyuz MS-11 crew to operate the station until the next crewed Soyuz arrival. During the increment, the crew supported station systems, visiting cargo vehicles, and a broad research program that included robotics work, wound-healing investigations, studies of disease development, and research tied to muscle conditions in microgravity. The crew also monitored visiting vehicle activity during the first uncrewed Crew Dragon Demo-1 flight to the station in March 2019, a key commercial crew test before later astronaut missions. Expedition 58 ended on March 15, 2019, when Soyuz MS-12 docked and expanded the station crew for the next increment.
