Fuelled with highly toxic Hydrazine .

Does it come with fried rice or noodles?

[youngmafbog]

This Spacestation is rubbery.

Ah, thank you very much.

[youngmafbog]

On a more serious note, surely it will burn up on re-entry?

[EDDIE51]

It is so heavy 8.5 Tonnes that parts are likely to survive without burning up.

I remember The Vapours but they were Turning Japanese.

It'll burn up. Even 10tonnes will easily burn up, especially as it is an irregular shape. The hydrazine should not really be an issue. It'll be dilute and may even react with atmospheric oxygen to make water and nitrogen

Que-mass hysteria, soothsayers

“Even 10tonnes will easily burn up”

Really?

[douglas9401]

Yup, really, except for the bits made from titanium and such. Seems parts strip away as it comes deeper into the atmosphere and friction increases and ordinary stuff like aluminium burn up.

Try rubbing your hands together really fast for ten seconds then multiply that heat by three, it's even hotter than that. :-)

10-tonnes is a very approximate threshhold for a solid iron-based meteorite reaching the ground.

https://www.nasa.gov/mission_pages/asteroids/overview/fastfacts.html

Man-made objects such as the above are not solid lumps of matter, so have a much higher surface area to mass ratio, which means they break up higher in the atmosphere, leading to multiple objects of much lower mass thanthe somewhat arbitrary 10-tonne threshhold.

Furthermore, small meteorites hit the atmosphere very regularly. Around 100 tonnes every day.

Those very few that reach the bottom of the atmosphere mostly land in the oceans with zero impact; those that hit the ground usually land in uninhabited areas.

Nothing to worry about here. move along, please.

[youngmafbog]

Approximately
70% of the earth is water
95% of the world’s population is concentrated in just 10% of the land surface.
3% of land is populated.

So your chances of being hit by this or a meterite that makes it way through are extremely slim.

Nothing like a good panic story though is there?

[Kidas]

As expected,
"China's Tiangong-1 space lab burned up in the atmosphere over the southern Pacific Ocean late last night (April 1), falling right in the middle of the window predicted by a number of organizations"

Apparently, none of it reached the bottom of the atmosphere.

Phew!
