An Out-of-control Chinese Space Station is Falling Towards The Earth! Should we be Worrying About Tiangong-1?

Scientists speculate that parts of Tiangong-1, weighing as much as 100kg may crash on the Earth’s surface.

China, October 16, 2017: An out of control Chinese space station, weighing 8.5 tonnes, is falling towards the Earth and will crash land on the surface within a few months, experts say.

The Chinese space laboratory, Tiangong-1, or the ‘Heavenly Palace’ was launched in 2011, symbolic of the hopes of the Chinese ambitions in space. It was also believed to be a stepping stone to establish China as a global ‘space’ superpower.

Tiangong-1 was used for multiple space missions, some of which even included astronauts – the space station was also visited by the first female astronaut from China, Liu Yang, in 2012.

Harvard astrophysicist Jonathan McDowell has now revealed that the space station is descending quickly to the earth and will crash on the planet’s surface ‘soon’.

The ‘Out of Control’ Tiangong-1

Scientists had long speculated the strange behavior of Tiangong-1. Finally, in 2016, officials at China’s CNSA space agency had confirmed that they had lost complete manned control of Tiangong-1 and that the space station would now be descending towards the Earth.

According to The Guardian, McDowell was quoted as saying “(we) expect it will come down a few months from now – late 2017 or early 2018.” 

Where Will Tiangong-1 Crash?

At the moment, is practically impossible for scientists and engineers to confirm about the precise landing site as the capsule is completely beyond human control.

Researchers believe the descent is now going to be guided and influenced by the wind.

The industry enthusiast Jonathan McDowell had previously told The Guardian that even a slight change in the atmospheric conditions could push the landing site “from one continent to the next.”

Does The Crash-Landing of Tiangong-1 Pose A Threat To Life?

Tiangong-1 is expected to hit the Earth’s surface is late 2017 or early 2018.

Scientists are also examining the possibility of the debris from the craft causing casualties upon landing. While most of the craft is expected to burn up in the atmosphere, parts weighing as much as 100kg can be expected to crash on the Earth’s surface.

The possibility of the debris from Tiangong-1 falling in populated regions cannot be precisely calculated, however authorities believe that is likely to not happen.

In May this year, China had additionally informed the United Nations “Committee on the Peaceful Uses of Outer Space” that the descent of the space craft will be closely monitored and the United Nations will be duly informed when it takes it final plunge.

Tiangong-1 will not be the first to descend from the space with parts of the debris falling on the Earth. Previously,

  • 1979: NASA’s gigantic Skylab space station, weighing 77-tonne uncontrollably shot down to the Earth with large chunks of the craft landing near Perth in Western Australia.
  • 1991: Soviet Union’s Salyut 7 space station, weighing 20-tonne had crashed to the Earth while it was still docked to another spacecraft called Cosmos 1686 and had broken up over Argentina, throwing debris all over the town Capitán Bermúdez.

Tiangong-1 had been launched on 29 September, 2011, as a long-term mission, with an aim to establish a Chinese outpost in space. However, the out of control Chinese space station is now expected to crash land on the Earth ‘soon’.

Australia Rejects U.N. Climate Report, Continues Using Coal

Australia is the world's driest inhabited continent.

Australia is rejecting the latest U.N. report on climate change, insisting coal remains critical to energy security and lowering household power bills.

The United Nations’ Intergovernmental Panel on Climate Change (IPCC) said in its report released Monday that global greenhouse gas emissions must reach zero by the middle of the century to stop global warming exceeding 1.5 degrees Celsius.

The authors warned that if warming was allowed to reach two degrees, the world would be on course toward uncontrollable temperatures.

They made special mention of coal, insisting that its use for power generation would have to fall to between zero and two percent of current usage.

The report has received a lukewarm response by Australia’s center-right government. It has said it has no intention of scaling back fossil fuel production because without coal, household power bills would soar.

Canberra also insists it is on target to meet its commitments under the Paris agreement, which attempts to unite every nation under a single accord to tackle climate change for the first time ever.

Australia earns billions of dollars exporting coal to China and other parts of Asia, while it generates more than 60 percent of domestic electricity.

Australia’s Environment Minister Melissa Price believes the IPCC report exaggerates the threat posed by fossil fuel.

“Coal does form a very important part of the Australian energy mixer and we make no apology for the fact that our focus at the moment is on getting electricity prices down,” Price said. “Every year, there is new technology with respect to coal and what its contribution is to emissions. So, you know, to say that it has got to be phased out by 2050 is drawing a very long bow.”

Australia has some of the world’s highest per capita rates of greenhouse gas pollution. A recent government report showed a failure to reduce levels of greenhouse gas pollution. The survey said that between January and March this year, Australia had its most elevated levels of carbon pollution since 2011.
