Video: Change of command aboard International Space Station

A veteran cosmonaut, a German volcanologist and a Navy test pilot-turned-astronaut undocked from the International Space Station and returned to Earth, descending through low clouds to a jarring touchdown on the frigid steppe of Kazakhstan to close out a 165-day stay in orbit.

The Canadian government announced Tuesday its intention to support the International Space Station through 2024, joining the United States and Russia as the major partners officially backing an extension of the global research project.

A Russian Soyuz ferry ship carrying a Russian cosmonaut and two NASA astronauts undocked from the International Space Station early Thursday, flew a lap around the 20-year-old outpost for a photo survey and then plunged back to Earth, making a pinpoint landing on the steppe of Kazakhstan to wrap up a 197-day stay in space.
