Live coverage: Three Chinese astronauts return to Earth

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.

A Long March 6 booster took off Tuesday from China with three commercial Earth observation satellites designed to record high-definition video and color imagery from a perch more than 300 miles above the planet.

One week after two cosmonauts and a NASA astronaut arrived at the International Space Station for a six-month stay, the three crew members they’re replacing packed up their Soyuz spacecraft for a fiery plunge back to Earth Wednesday evening to close out a 196-day mission.
