China’s Space Station Will Crash To Earth Within Months

China’s aim was to set up a larger space complex after launching its first space station in 2011.

But the Chinese space agency lost control of Tiangong-1 in September 2016, and now experts predict the 8.5 tonne craft will come crashing back down to Earth within months.

Disturbingly, experts are uncertain exactly when the space station will head towards Earth, or where the debris will land.

Chinese officials confirmed that they had lost control of the spacecraft in September 2016, and have now foretold that it will come down to Earth between October 2017 and April 2018.

The station’s orbit has also been gradually decaying, and in recent weeks it has started to fall faster.

Speaking to the Guardian, Dr Jonathan McDowell, an astrophysicist from Harvard University, said: ‘Now that [its] perigee is below 300km and it is in denser atmosphere, the rate of decay is getting higher.

‘I expect it will come down a few months from now – late 2017 or early 2018.’

The Chinese space agency has been tracking the space station, and swore to issue warnings if there are any potential collisions looming.

But not everyone is convinced by this.

Thomas Dorman, an amateur satellite tracker, 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.

‘It could be a real bad day if pieces of this came down in a populated area, but odds are it will land in the ocean or in an unpopulated area.’

Much of the spacecraft is expected to burn up in the atmosphere upon re-entry.

But Dr McDowell says that some parts might still weigh up to 100kg when they crash into the Earth’s surface, a size that could cause some serious damage.

And Dr McDowell added that we may only have hours of warning about where the spacecraft will land.

He said: ‘You really can’t steer these things.

‘Even a couple of days before it re-enters we probably won’t know better than six or seven hours, plus or minus, when it’s going to come down.

‘Not knowing when it’s going to come down translates as not knowing where it’s going to come down.’

Tiangong-1, which means ‘Heavenly Palace’, was launched in September 2011 with the hope of creating a larger space complex that China wants to be operational in Earth orbit around 2020.

The module performed a series of docking exercises, including the uncrewed Shenzhou-8 mission in 2011 and the crewed Shenzhou-10 mission in 2012.

According to the China Manned Space Engineering (CMSE) office, Tiangong-1 also contains Earth observation instrumentation and space environment detectors.

In a statement in 2014, officials from CMSE, said: ‘Tiangong-1 has obtained a great deal of application and science data, which is valuable in mineral resources investigation, ocean and forest application, hydrologic and ecological environment monitoring, land use, urban thermal environment monitoring and emergency disaster control.’

  1. Because the house is too dangerous, some villagers prefer to borrow from relatives and are not willing to “private rooms.” In another household without a “private room” villager, many parts of the house’s outer wall have collapsed. There are not only many cracks in it, but the wall behind it has been sunken and deformed. The roof above has been run down because of the rain.
