Live coverage: International crew lands in Kazakhstan

A SpaceX-owned supply ship arrived at the International Space Station on Sunday with 2.4 tons of cargo, including space debris and solar energy monitors mounted in the Dragon spacecraft’s external payload bay and more than 3,400 pounds of gear inside its reused pressurized module.

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).

The maiden flight of NASA’s Space Launch System, a heavy-lift human-rated rocket and one of the agency’s core programs, will likely not be ready for takeoff until 2020, officials said recently.
