China's first space station may crash to Earth as soon as Thursday

Source: Business Insider

China's first space station, called Tiangong-1 or "Heavenly Palace," will soon break up over Earth into a fiery rain of space junk.

The Aerospace Corp., a nonprofit spaceflight research company, has released its newest prediction about the derelict spacecraft's doom. Tiangong-1 may reenter Earth's atmosphere on April 1, give or take three days — which means the dead spacecraft could come crashing down as soon as Thursday, March 29.

When it does, extreme heat and pressure caused by plowing through the air at more than 15,000 mph will destroy the roughly 9.4-ton vessel. Not everything may vanish, though.

There's a good chance that gear and hardware left on board could survive intact all the way to the ground, according to Bill Ailor, an aerospace engineer who specializes in atmospheric reentry. That durability is thanks to Tiangong-1's onion-like layers of protective material.

with George Clooney flaunting the laws of physics again? Someone really, really needs to deorbit the both of them.

However, this situation makes me wonder whether this is a violation of the tariffs against China?

I'd guess mostly aluminum and other light alloys. Maybe some tough, light titanium, too.

That thing is going to mostly burn up. But the inner structures more likely to survive as the article states.

One thing for sure, it's going to put on quite a show. People with iPhones are going to be busy. I'd like to see an HD film of it.

The yellow bands are highest probability. Green is low probability. Blue is zero probability.

I notice that my state, Michigan, is ground zero in the south of the state. I live just north of that in the skinny green band.

Might get out the binocs when it is projected to come down and have a look see.

If it comes down in the Southern Hemisphere (about 50% chance now) it will likely hit the ocean. Except, poor Tasmania and the Kiwis.

My father built a Spirograph just because he wanted. It was very clever.

Look at the slope of the orbit in the yellow zone.

The yellow zone is the highest probability because that's where the space station spends the most time.

Sorry. But you are wrong.

My best to you.

I'd still bet it deorbits and crashes to earth in the green zone, though.

Guess we'll get the answer in a week or so!
