Tiangong-1 was launched in September 2011 as a prototype for China's ultimate space goal: a permanent space station which is expected to launch around 2022. But the Chinese government told the United Nations in May 2017 their space lab had "ceased functioning" in March 2016, without saying exactly why.
An updated ESA forecast issued today (March 30) said the 8.5-metric-ton (9.4 tons) space lab will fall to Earth later in the day on April 1. That's because the sun's activity is weaker than expected, ESA explained.
There's no need for concern however, scientists have emphasized the danger of being hit by falling debris is tiny, as low as one in 1 trillion, as the structure is likely to burn up in the atmosphere during reentry. "There is no need for people to worry about its re-entry into the atmosphere," an article by the China Manned Space Engineering Office published on state media said. "It won't crash to the Earth fiercely, as in sci-fi movie scenarios, but will look more like a shower of meteors."
Update: Tiangong-1 is now forecast to re-enter Earth's atmosphere on April 1 at 12:15 p.m. EDT (1615 GMT), give or take 9 hours, according to the Aerospace Corp. The Stations path could still change but as of now, we are expecting it to pass over NE Ohio.
