Live coverage: International crew lands in Kazakhstan

A Russian cosmonaut, a NASA flight engineer and a Japanese physician-astronaut strapped into their Soyuz ferry ship early Sunday, undocked from the International Space Station and plunged back to Earth, landing on the steppe of Kazakhstan to close out a 168-day mission.

Launch of a Russian Soyuz spacecraft Friday carrying three fresh crew members to the International Space Station will boost the lab’s crew back to six and, most important from NASA’s perspective, dramatically boost research with four crew members — three NASA astronauts and a veteran European flier — available to operate experiments in the American segment of the laboratory.

SpaceX and NASA launched a planet-hunting satellite Wednesday from Cape Canaveral, two days after calling off a launch attempt to conduct additional guidance, navigation and control analyses. Liftoff occurred at 6:51 p.m. EDT (2251 GMT), and the first stage of the Falcon 9 rocket successfully landed on a drone ship in the Atlantic Ocean.
