He said Tiangong-1's landing site in the Pacific Ocean represents "kind of where you hope it would".

Tiangong-1 had not been occupied for three years, so there was no way of knowing for certain where it would land.

The station may have landed north-west of Tahiti, Jonathan McDowell, an astronomer at the Harvard-Smithsonian Centre for Astrophysics, said on Twitter.

Anyone who sees what could be debris from the station known as "Heavenly Place: should not touch it or inhale its fumes, Aerospace Corp. warns".

Ideally, the defunct Chinese station should have been de-orbited in a planned manner, but this was not possible after the loss of command links with the station in 2016.

As Mike Wall writes for Space.com, the U.S. Strategic Command's Joint Force Space Component Command (JFSCC) reported that the prototype space station broke apart and is thought to have largely burned above the southern Pacific Ocean as it re-entered the Earth's atmosphere Sunday at about 8:16 p.m. E.D.T.

According to the China Manned Space Engineering Office there is "no need for people to worry".

It is common for an outside agency to handle the investigation into an officer-involved shooting. The injured officer was taken to the hospital, where he was treated for swelling and bruising.

Investigators say Elsbeth Kittinger, 49, of Fort Worth, Texas, shot Sheldon when she was asked to get out her pick-up. Five miles further down the road, Kittinger was reportedly met by another officer who opened fire, wouding her.

The fall of Tiangong-1 was monitored by the Inter-Agency Space Debris Coordination Committee, an global group that included NASA, the ESA as well as the space agencies of 11 other nations.

"Everyone thinks they're going to get hit by the Chinese space station". And it described the probability of someone being hit by a piece of debris from Tiangong-1 as "10 million times smaller than the yearly chance of being hit by lightning".

In 1979, the National Aeronautics and Space Administration's (NASA) first space station, Skylab fell to Earth during its re-entry to the atmosphere, burning up harmlessly in the process. It has been used twice to practice how taikonauts, China's term for its astronauts, would dock to a space station.

Within a year after Tiangong had stopped working, China launched a second space lab, Tiangong-2, whose aim is to test capabilities for long-term human presence in space, in anticipation of a permanent space station to be launched in 2023. China lost contact with the station in 2016, so the exact position was unknown.

This TV grab taken on 2 November 2011 shows an animated video clip of the docking of the Tiangong-1 space lab module and the Shenzhou VIII (Shenzhou-8) spacecraft in space. The agency also plans to put a man on the moon and send a mission to Mars, according to CNN.

When space stations come down, "a amusing thing" happens that helps doom the spacecraft, Jesse Gossner, an orbital-mechanics engineer who teaches at the US Air Force's Advanced Space Operations School, previously told Business Insider.
