Chinese space station’s debris may crash to earth on Friday, Scientists say

Debris from a defunct Chinese space station could crash to earth as early as Friday, scientists monitoring it have said.

The Tiangong-1 was part of China’s ambitious space programme, and the prototype for a manned station in 2022.

It was put into orbit in 2011 and five years later completed its mission, after which it was expected to fall back to Earth.

Time and place of impact are hard to predict as it is no longer controlled.

The latest estimate for re-entry is between 30 March and 2 April.

Most of the station is likely to burn up in the atmosphere but some debris could survive to hit the surface of the Earth.

The station is gradually coming close to Earth.

Its rate of descent “will continually get faster as the atmosphere that the station is ploughing through gets thicker,” Dr Elias Aboutanios, Deputy Director of the Australian Centre for Space Engineering Research, told the BBC.

“The station will eventually start to heat up as it gets close to 100km [from Earth],” he said.

This will lead to most of the station burning up and “it is difficult to know exactly what will survive since the makeup of the station has not been disclosed by China”.

Aboutanios said if it does burn up during night time over a populated area, it “will most certainly be visible, like a meteor or a shooting star”.
