China's 8.5-tonne space lab could fall to Earth by March
Decommissioned space laboratory Tiangong-1, which had been declared "out of control" by China in 2016, could reportedly re-enter the Earth's atmosphere around March. While "most" of the 8.5-tonne station is expected to burn during re-entry, experts fear humans could come in contact with remnants of toxic rocket fuel. Launched in 2011, Tiangong-1 has hosted several unmanned and manned missions.
