China’s third unmanned spacecraft returned to Earth on Monday after spending a week in orbit. The Shenzhou capsule, touched down in northern China’s Inner Mongolia Autonomous Region at 0851 GMT (3:51am EST). The spacecraft contained a series of experiments designed to test the life support systems of the capsule. It’s still unknown when China will actually send humans into space, but officials from the country’s space agency said that more unmanned tests will still be required.
