When Will China's 'Heavenly Palace' Space Lab Fall Back to Earth?

A Chinese space lab is bound to come back to Earth relatively soon, but when and where this happens is a matter of debate and speculation. For example, some satellite trackers think China may have lost control of the uncrewed 8-ton (7.3 metric tons) vehicle, which is called Tiangong-1. "If I am right, China will wait until the last minute to let the world know it has a problem with their space station," Dorman told Space.com.
