China's Tiangong-1 Space Lab expected to fall to Earth in 2 to 3 weeks

The European Space Agency’s (ESA) Space Debris Office in Darmstadt, Germany, has issued a new update on the expected re-entry of China’s Tiangong-1 space lab.

The new forecast, which was issued March 15, predicts that the 8.5-ton Tiangong-1 will fall back to Earth between March 30 and April 6, though it stresses that this is a rough estimate.

"At no time will a precise time/location prediction from ESA be possible," Space Debris Office officials wrote in the update.

Tiangong-1, the first space station built by China, launched in late September 2011. The first Chinese orbital docking occurred between Tiangong-1 and an unpiloted Shenzhou spacecraft on Nov. 2, 2011. Two piloted missions visited Tiangong-1 as well: Shenzhou 9 and Shenzhou 10, in June 2012 and June 2013, respectively.
