China's Tiangong-1 space station to crash to Earth within weeks

China's Tiangong-1 space station to crash to Earth within weeks

The highest-probability zones are also as they were in January: northern U.S. states, a chunk of southern Europe into western Asia, China, and the two Koreas (great), or south of the equator, Argentina, Chile, Tasmania in Australia, or New Zealand.

Suffice to say, you'd be very unlucky to look up and see a slab of Tiangong-1 hurtling towards you.

The Long March II-F rocket carrying China's Tiangong-1 lifts off from the Jiuquan Satellite Launch Center, Gansu province September 29, 2011. It was hard to predict when the module might land because its speed was affected by the constantly changing "weather" in space, he said.

Bottom line: China's first space station will undergo an uncontrolled re-entry into Earth's atmosphere sometime in the March-April timeframe. But, in 2016 the Chinese aerospace agency informed that it has lost the control over the space station and they will not be able to carry out a controlled re-entry. "Should this happen, any surviving debris would fall within a region that is a few hundred kilometres in size and centred along a point on the Earth that the station passes over".

The likelihood of being hit by some of the Chinese space junk in the descent is statistically around a million times smaller than the odds of winning the Powerball jackpot, according to the Aerospace Corporation.

Every satellites and space station, to maintain their assigned orbit need little push and initially, Tiangong-1 followed all the ground command for few years and stayed perfectly in its assigned orbit, but in 2016, the Chinese space agency lost the control over it and now it is on its way to hit the Earth.

The statement also mentioned that the module is expected to re-enter somewhere between 43 degrees north and 43 degrees south latitudes.

"No one has ever been hurt by a piece of debris landing from space". As per the reports, Tiangong-1 carries a highly toxic and corrosive fuel named Hydrazine.

"Even a couple of days before it re-enters we probably won't know better than six or seven hours, plus or minus, when it's going to come down", Harvard astrophysicist Jonathan McDowell told The Guardian. China's first space station will come into collision with our planet within weeks.

In 1991 the Soviet Union's 20-tonne Salyut 7 space station crashed to Earth while still docked to another 20-tonne spacecraft called Cosmos 1686.

Used for both manned and unmanned missions, it was visited by China's first female astronaut Liu Yang in 2012. However, one woman walking in an Oklahoma park in 1997 was struck by fragments of a burned-up Delta 2 rocket - though she was not injured.

Nasa's 77-tonne Skylab space station came hurtling to Earth in an nearly completely uncontrolled descent in 1979, with some large pieces landing outside Perth in Western Australia.
