In September a year ago, however, scientists at China's CNSA space agency admitted to having lost control of the lab, saying that it would be crash-landing on Earth.
Chinese officials told the United Nations in 2016 they had lost the ability to correct the station's altitude and expected it to plummet to the ground between October 2017 and April 2018.
And there won't be much advance notice of when it does make impact, as scientists will have just a few hours of heads up when Tiangong-1 will crash and therefore rare.
But in 2016, after months of speculation, Chinese officials confirmed they had lost control of the space station and it would crash to Earth in 2017 or 2018.
The first prototype Space Station of China Tiangong-1 will crash on Earth in the late 2017 or at the beginning of 2018, the Guardian reported.
According to Harvard astrophysicist Jonathan McDowell speaking to the Guardian, the Chinese space station is accelerating its fall towards Earth and will reach the ground in the coming months. It is decaying quickly and he expects "expect it will come down a few months from now - late 2017 or early 2018", he said. It was the first space station launched and operated by NASA.
Tiangong-1 was visited by a series of Shenzhou spacecraft during its two-year operational lifetime. Despite that, Tiangong-1 stopped sending signals in February 2016. After the last crew departed the module in June 2013 it was put into sleep mode and it was intended that it would remain in orbit for some time, allowing China to collect data on the longevity of key components before being commanded to gradually re-enter the atmosphere.
An amateur satellite tracker, Thomas Dorman, told Space.com: "If I am right, China will wait until the last minute to let the world know it has a problem with their space station". The launch mass of the Tianzhou cargo spacecraft is expected to be around 13 metric tons (29,000 lb), with a payload of about 6 metric tons (13,000 lb).
An 18,752 pounds space station, 34 feet by 11 feet in size, was launched in 2011 for both manned and unmanned missions. It was launched in 1973 and completed 2,249 days in its orbit before it finally fell in Western Australia.
