China's Tiangong-1 space station is forecast to re-enter the earth's atmosphere over a remote part of the South Atlantic between 8:11 a.m. and 9:33 a.m. (0011-0133 GMT) on Monday, the country's space authority said. The craft is expected to re-enter in an area around 19.4 degrees west, 10.2 degrees south, the authority said on its website, giving it a position southwest of the tiny British South Atlantic island of Ascension. Beijing said on Friday it was unlikely any large pieces would reach the ground. The 10.4-metre-long (34.1-foot) Tiangong-1, or "Heavenly Palace 1", was launched in 2011 to carry out docking and orbit experiments as part of China's ambitious space programme, which aims to place a permanent station in orbit by 2023. It was originally planned to be decommissioned in 2013 but its mission was repeatedly extended. China had said its re-entry would occur in late 2017 but that process was delayed, leading some experts to suggest the space laboratory is out of control.
