Russian commander Oleg Kononenko, Canadian co-pilot David Saint-Jacques and NASA flight engineer Anne McClain closed out a 204-day mission in orbit Monday with an undocking from the International Space Station at 7:25 p.m. EDT (2325 GMT), followed by landing in Kazakhstan aboard their Soyuz MS-11 capsule at 10:47 p.m. EDT (0247 GMT Tuesday).

NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko are gearing up for launch March 27 to kick off a record one-year stay aboard the International Space Station, an orbital marathon both men say is crucial for planning future flights beyond Earth orbit and, eventually, to Mars.

Nearly two days after launching from Cape Canaveral, SpaceX’s Dragon cargo craft arrived at the International Space Station on Saturday with more than 5,000 pounds of supplies, food, experiments and a new docking mechanism. Astronauts aboard the station captured Dragon using the Canadian-built robotic arm at 9:11 a.m. EDT (1311 GMT).
