HIGH ALERT: Uncontrolled Chinese space station could destroy Monaco
Uninhabitable Chinese space station with toxic chemicals could collapse next week in the earth and Monaco and parts of Europe are among the ‘most likely’ targets.
An uncontrolled Chinese space station with ‘very toxic’ chemicals on board can hit a number of major world cities,…..
including Monaco, New York, Rome, Barcelona suggests research. The first prototype of China, Tiangong-1, will return to the planet between 30 March and 6 April, experts say.
It has the greatest chance of crashing in cities along a narrow strip around latitudes of 43 degrees north and south.
This includes a number of highly populated cities, including New York, Barcelona, Beijing, Chicago, Istanbul, Rome and Toronto.
It is most likely that these places hit because it travels parallel to the equator at the most northern and southern points of its orbit.
From our perspective on earth, it seems to travel more slowly above these areas, thanks to the geometry with respect to the earth, although the speed remains virtually constant.
Because it takes longer to cross the earth’s surface at these latitudes, the risk is greater that you will come down here.
The doomed 8.5-tonne vessel, which has been rushing to Earth since the control was lost in 2016, is believed to contain dangerous hydrazine.
Scientists only know the exact date on which the effect will take place and exactly where the debris will fall during the final weeks of its decline.
Explanation why this is so. Hugh Lewis, associate professor of aerospace engineering at the University of Southampton, compared the geometric processes at work with crossing the road.
He told MailOnline: ‘The spacecraft travels around in a more or less circular orbit, which is tilted at an angle of 43 ° to the equator.
‘If you plot this path on a map of the earth, it produces a sine wave pattern, with the slower curvature of the wave in northern and southern latitudes and the faster straighter sections running from east to west.
“If you imagine that the green low-risk area on the map is the part of the road that we are trying to cross, the fastest way to go 90 degrees is straight ahead.
“When the spacecraft crosses the equator, it crosses the road at this point, and it does it so quickly.
‘When it goes over the red bands further north and south, it crosses a steeper angle – almost parallel to the road.
‘It takes longer to cross at these latitudes, which gives us a higher risk of coming here.’
Predictions of the most likely effect of Tiangong-1 are from Aerospace, a US research organization in El Segundo, California, which advises government and private companies on space flights.
It says that the space station will enter the atmosphere of the earth on April 4, give it a week or take it up, and debris will not fall further north than 42.7 ° north latitude or south of 42.7 ° south latitude. These zero probability areas, marked as safe if Tiangong-1 does not fly, form about a third of the total surface of the earth. A particular risk in the northern hemisphere are northern parts of the US, including Boston, Des Moines, Detroit, Milwaukee, Philadelphia and Salt Lake City. Florence, Italy, the city of Monaco and Sochi, Russia, are also in the region with the higher risk.
In the southern hemisphere other cities that may be affected are Trelew, Argentina, Christchurch, New Zealand and Sapporo, Japan.
Experts from the European Space Agency (ESA), based in Paris, are among those who follow Tiangong-1, which means ‘heavenly palace’.
Their Space Debris Office in Darmstadt, Germany, made a revised forecast date for re-entry on 30 March and 6 April in recent days.
This narrows from their previous estimate of 29 March and 9 April.
Exactly where it will hit is slightly more difficult to predict.
When he responded with MailOnline, Dr. Lewis adds: “We can not say exactly where, because we do not know what job it will be in. At the moment it is very difficult to say, and in recent months the spacecraft has been speeding up and it is now falling. than 6 km (3.7 miles) a week, in October it was 1.5 kilometers per week.
“Every few years something like this happens, but Tiangong-1 is big and compact, so we have to keep an eye on it,” Jonathan McDowell, an astrophysicist at Harvard University, told The Guardian.
