News today 11.03.2018 space: Chinese Space station with "highly toxic" chemicals on Board, which is now uncontrollably heading for Earth, may fall directly in the territory of MI, of the United States, according to estimates.
Tiangong-1 is now at an altitude of 150 miles and is the focus of multiple space agencies looking to predict when and where it will crash.
"Although not declared officially, it is suspected that control of Tiangong-1 was lost and will not be regained before re-entry", it said. For your safety, do not touch any debris you may find on the ground nor inhale vapors it may emit, ' said a warning from Aerospace Corporation's Center for Orbital and Reentry Debris Studies (CORDS). The space station is believed to contain the toxic chemical hydrazine.
In addition, there is a high chance of dropping in the North China, Central Italy, Middle East, New Zealand, Tasmania, South America, South Africa and Northern States of the USA.
While most of it will burn up during re-entry, around 10 to 40 per cent of the satellite is expected to survive as debris, and some parts may contain risky hydrazine and could weigh up to 220lb.
An Aerospace analysis found that "the risk that an individual will be hit and injured by a piece of debris is estimated to be less than one in a one trillion". Predicting where any debris could hit is next to impossible, according to Harvard University astrophysicist Jonathan McDowell. He said fragments from a similar-sized rocket re-entered the atmosphere and landed in Peru in January.
For now, ground stations are able to track Tiangong-1 as it speeds along at 16,000 miles an hour some 180 miles above Earth.
In recent months, the spacecraft has been speeding up and it is now falling by around 6km (3.7 miles) a week.
While this estimate seems imprecise, ESA said that it will land somewhere in northern latitudes.
"It is only in the final week or so that we are going to be able to start speaking about it with more confidence", said Dr McDowell. "During its re-entry, most of its parts will burn up through the atmosphere, leaving only a few to land on Earth". We know that the space station is coming down, we just don't know when or where.
The 8.5-ton Tiangong-1 space laboratory, which means "Heavenly Palace", was launched on September 30, 2011.
It was used for both manned and unmanned missions and visited by China's first female astronaut, Liu Yang, in 2012.
Scientists have been making assumptions to predict the spot of the crash, however, it is unlikely since Tiangong-1 will face erratic behavior when near Earth's atmosphere and gravity which will tear it apart even before crashing on the surface. They broke up over Argentina, scattering debris over the town of Capitan Bermudez.
