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’.

2015 Agreement to Bring Peace to Ukraine’s East Remains Unimplemented

Ursula Mueller, the U.N.'s deputy humanitarian chief, said the conflict is causing severe humanitarian problems.

A 2015 agreement to bring peace to Ukraine’s volatile east remains largely unimplemented and civilians are paying the highest price, with more than 3,300 killed and 3.5 million needing humanitarian aid this year, U.N. officials said Tuesday.

Russia’s annexation of the Crimean Peninsula in early 2014 and support for separatist rebels in the east triggered a conflict with Ukrainian government forces that the U.N. says has also injured up to 9,000 civilians and displaced 1.5 million people.

Assistant Secretary-General Miroslav Jenca told the Security Council that negotiations “appear to have lost momentum,” with Russia and Ukraine unable or unwilling to agree on key steps forward or too distracted to focus on implementing the 2015 agreement.

Russian Ambassador Vassily Nebenzia and Ukrainian Ambassador Volodymyr Yelchenko blamed each other for the failure to implement the agreement signed in the Belarus capital, Minsk.

Jenca, who is in charge of European affairs, stressed that the conflict in eastern Ukraine is not dormant. “It is a conflict in the heart of Europe which continues to claim victims,” he said.

Jenca said the main parties have committed to over a dozen cease-fires since the start of the conflict, but “each one was regrettably, short-lived.”

The Organization for Security and Cooperation’s monitoring mission in Ukraine reports that the military positions of both sides are coming closer to each other in the “gray areas” near the so-called “contact line,” he said. “The use of heavy weapons and their deployment in the proximity of the contact line is a reality.”

Ursula Mueller, the U.N.’s deputy humanitarian chief, said the conflict is causing severe humanitarian problems, noting that many of the 3.5 million people who need aid are elderly, women and children.

“Many are struggling to access schools, hospitals and other essential services,” she said. “Many have lost their jobs, homes, family members and friends.”

Mueller said the U.N. has appealed for $162 million this year to aid 2.3 million people.

Ertugrul Apakan, chief of the OSCE monitoring mission in Ukraine, told the council by video that many people use checkpoints in eastern Donetsk and Luhansk to receive pensions and see families separated by the conflict. Since December, he said, there have been “14 cases of people who died from natural causes while waiting at the checkpoints.”

Mueller said most of those who died this year were elderly. People wait for several hours in freezing temperatures to cross the contact line, and she urged better conditions and additional crossing points, especially in Luhansk where there is only one.

Before the meeting, eight former and current European Union members of the Security Council issued a joint statement urging humanitarian access to areas not under Ukrainian government control.

They called on Russia “to immediately stop fueling the conflict by providing financial and military support” to the separatists and reiterated their opposition to Moscow’s annexation of Crimea. Nonetheless, they said, they “remain convinced that a peaceful resolution of the conflict is possible.”

Nebenzia said Russia called the council meeting to discuss implementation of the 2015 agreement, declaring that the situation in southeastern Ukraine “remains explosive” with positions now “too close to each other at some locations.” He said Ukraine “comprehensively and consciously ignores and sabotages the Minsk agreements and our Western partners cover up for all of its unlawful acts.”
