Live coverage: Three Chinese astronauts return to Earth

In a mission marking the end of an era, NASA astronaut and former virus hunter Kate Rubins, using NASA’s last currently contracted seat on a Russian Soyuz spacecraft, blasts off Wednesday with two cosmonaut crewmates on a flight to the International Space Station.

Two Chinese spacecraft designed to test inter-satellite network and Earth observation technologies launched Wednesday on top of a Long March 2C booster.

NASA and Roscosmos, the Russian space agency, have agreed to extend astronaut Peggy Whitson’s stay aboard the International Space Station by three months to enable uninterrupted research aboard the orbital laboratory during a period when Russia is temporarily reducing its crew complement, the U.S. space agency said Wednesday.
