CHINA'S DOOMED SPACE STATION: China's Tiangong-1 space station is about to return to Earth--as a massive fireball. According to the European Space Agency (ESA), the 8-ton spacecraft will re-enter the atmosphere sometime between March 30th and April 2nd. Tiangong-1 is about the size of a European cargo spacecraft, such as the ATV-1 which itself re-entered in 2008.

Tiangong-1 is currently predicted to reenter the Earth’s atmosphere around April 1st, 2018 ± 2 Days. This prediction was performed by The Aerospace Corporation on 2018 March 26.

Once it reenters and breaks up, what is the risk that any pieces reach ground?

Tiangong-1 is a large spacecraft comparable in size and mass to other, frequently used space stations and cargo vessels such as ESA’s ATV, the Japanese HTV, Russian Progress and American Dragon or Cygnus.

From monitoring the controlled reentries of those types of spacecraft, it can be surmised that Tiangong-1 will break up during its atmospheric re-entry and that some parts will survive the process and reach the surface of Earth.

Given the uncontrolled nature of this reentry event, the zone over which fragments might fall stretches over a curved ellipsoid that is thousands of kilometres in length and tens of kilometres wide. While a wide area could be affected, it is important to point out that a large part of the Earth is covered by water or is uninhabited.

Hence the personal probability of being hit by a piece of debris from the Tiangong-1 is actually 10 million times smaller than the yearly chance of being hit by lightning.

In the history of spaceflight, no casualties due to falling space debris have ever been confirmed.
