Chinese Space Station Tiangong-1’s Crash to Earth: Everything You Need to Know

Tiangong-1 Crashing back to Earth between March 30 and April 2

It is the Chinese space station Tiangong-1 (in Chinese, “Star Palace-1”), launched on September 30, 2011 as part of an ambitious scientific project to turn China into a space superpower. But since 2016, the space station was abandoned and replaced by the Tiangong-2, which resulted in its loss of control and its inevitable descent to Earth.

Tiangong-1 will re-enter the Earth’s atmosphere during the first week of April, however there is a window of uncertainty when the space station will crash to Earth.

The spacecraft is likely to burn up upon re-entry, however scientists have warned there is a chance a small amount of debris could survive re-entry and hit the Earth.

What is China’s Tiangong-1 station?


Tiangong-1, which translates to mean “Heavenly Palace-1”, is operated by the China Manned Space Engineering Office (CMSE).

It was launched by China’s National Space Administration (CNSA) without anyone aboard on September 29, 2011.

The 40-foot space station was a prototype for China’s large modular space station, which is expected to launch around 2022.

The orbit of the Tiangong-1 station is about 217 miles (350km) above Earth, which is lower than the International Space Station, whose average altitude is 250 miles (400km).

Tiangong-1 measures 9.4 ton (8.5 metric tons) and is about 34 feet long by 11 feet wide (10.4m by 3.4m).

It was used for both manned and unmanned missions and visited by China’s first female astronaut, Liu Yang, in 2012.

However the space station “ceased functioning” on March 16. 2016, China told the United Nations in May 2017 and therefor they are unable to perform a controlled re-entry.

The space station will fall back to Earth on its own, pulled down by atmospheric drag.

When will it fall to Earth?


There are various reports when the space station will fall to earth.

The European Space Agency (ESA) said Tiangong-1 space station will re-enter the Earth’s atmosphere between March 30 and April 2, however it warned the estimate was “highly variable.”

The China Manned Space Engineering Office said it expected the lab to re-enter the atmosphere between March 31 and April 4, burning up in the process.

Aerospace Corporation, a non-profit spaceflight research company, said the space station will re-enter the atmosphere around April 1 – or three days either side of that date.

Jesse Gossner, an orbital mechanics engineer who teaches at the US Air Force’s Advanced Space Operations School told Business Insider the uncertainty over when the space station will land is due to the nature of Earth’s atmosphere and how high-speed objects behave in it.

“You’d be surprised just how inaccurate and random it is because of the atmosphere. Have you ever skipped a stone on a lake.
