Live coverage: SpaceX supply ship returns to Earth

A SpaceX Dragon cargo freighter departed the International Space Station Tuesday for return to Earth, wrapping up the 20th and final visit to the orbiting research complex for the current version of SpaceX’s supply ship before an upgraded Dragon starts launching later this year. Release from the space station’s robotic arm occurred at 9:06 a.m. EDT (1306 GMT), followed by splashdown in the Pacific Ocean at 2:50 p.m. EDT (1850 GMT).

China’s Tiangong 1 space lab, home to two astronaut crews in 2012 and 2013, fell back to Earth uncontrolled Sunday, likely burning up over the Pacific Ocean as satellite trackers monitored the module’s gradual descent from orbit.
