Den kinesiska rymdstationen Tiangong-1 (Himmelsk plats" lär det betyda),
somsköts upp 2011, är utom kontroll och befaras snart störta:

"It marked successful docking exercises between 2011 to 2013 but ever since it
has been floating in an in-orbit “operation management phase”.
According to the China Manned Space Engineering (CMSE) office, between 2011 to
2014, Tiangong-1 “has obtained a great deal of application and science data,
which is valuable in mineral resources investigation, ocean and forest
application, hydrologic and ecological environment monitoring, land use, urban
thermal environment monitoring and emergency disaster control.”
But earlier this year, China’s state-run xinhuanet.com reported, “After an
operational orbit of 1630 days, China’s first space lab Tiangong-1 terminated
its data service.
“The flight orbit of the space lab, which will descend gradually in the coming
months, is under continued and close monitoring, according to the office, which
said the orbiter will burn up in the atmosphere eventually.
...there’s a high possibility it will reach Earth before it melts away.
One amateur astronomer, who has been tracking the space station’s movements
using telescopes, binoculars and video cameras, believes Tiangong-1 is on a
crash course towards Earth, and China isn’t doing anything to stop it.
It is expected to make its return to ground late 2017, but China has remained
tight-lipped about when — and where — it might happen.
“If I am right, China will wait until the last minute to let the world know
it has a problem with their space station,” Amatuer satellite tracker Thomas
Dorman told Space.com from his home in El Paso, Texas.
“It could be a real bad day if pieces of this came down in a populated area,
but odds are it will land in the ocean or in an unpopulated area."
