Part of a huge rocket that launched China’s first module for its Tianhe space station is falling back to Earth and could make an uncontrolled re-entry at an unknown landing point.

The 30-metre high core of the Long March 5B rocket launched the “Heavenly Harmony” unmanned core module into low Earth orbit on 29 April from Wenchang in China’s Hainan province.

The Long March 5B then itself entered a temporary orbit, setting the stage for one of the largest ever uncontrolled re-entries. Some experts fear it could land on an inhabited area.

“It’s potentially not good,” said Jonathan McDowell, Astrophysicist at the Astrophysics Center at Harvard University.

 

Since the weekend it has dropped nearly 80km in altitude and Space

News reported that amateur ground observations showed it was tumbling and not under control. This, and its speed, makes it impossible to predict where it will land when Earth’s atmosphere eventually drags it down, though McDowell said the most likely outcome is that it will fall into the sea, as the ocean covers about 71% of the planet.
