China's Tiangong-1 Space Laboratory is due to fall to Earth this weekend



The China Manned Space Engineering Office sets the date for re-entry a little later, between April 1 and April 2. Earlier estimates indicate the date for the 4th of April.

Scientists have pointed out the danger of falling debris It is tiny, as low as one to one trillion, as the structure is likely to burn on re-entry into the atmosphere.

"There is no need for people to worry about their re-entry into the atmosphere," said an article in the China-manned space engineering bureau published on state media.

"It's not going to crash violently on Earth as it does in science fiction movie scenes, but more like a flood of meteorites."

The Tiangong-1
was launched in September 2011 as a prototype for China's ultimate space target: a permanent space station expected to start around 2022.
But the Chinese government declared its space laboratory to the United Nations in May 2017 had "stopped functioning" in March 2016, without saying exactly why.

Although the China Space Program incident was embarrassing, it has not delayed progress. In September 2016, the Tiangong-2 space laboratory was successfully launched and put into orbit.

Witnesses can see "series of fireballs"

Markus Dolensky, technical director According to witnesses of the Tiangong 1 descent, "series of fireballs" were supposed to cross the sky – provided there were no clouds.

"It is now approaching its fiery death as it is gradually slowing down from the edges of the upper Earth's atmosphere," he said.

While it is not uncommon for debris such as satellites or spent rocket stages to fall to Earth, larger ships that can support human life are rarer.

NASA's first space station, Skylab, fell to the ground in 1979, reentering it out of control and burning it harmlessly.
The last space outpost was Russia's 135-ton Mir Station in 2001, which made a controlled landing, with most of the pieces breaking in the atmosphere. The reentry area of ​​the Tiangong-1 is expected to be 43 degrees north and 43 degrees south of the equator, a huge stretch of the earth that stretches from New York to Cape Town. Scientists say it's not possible to say exactly where that happens.

"Some parts of the upper atmosphere are thicker than others, meaning that the ship will unpredictably slow down and move around the earth in just 90 minutes, even an uncertainty of two minutes means the ship is somewhere along a thousand kilometers long distance could fall. " Alan Duffy, a researcher at the Center for Astrophysics and Supercomputers at the Swinburne Technical University in Australia, said.
