BEIJING- China’s first experimental space lab is expected to come crashingback to Earth between March 31 and April 4.

Space authorities said that the space lab should burn up in the atmosphere.

Tiangong-1 has officially stopped sending data and entered its final phaseof life on March 16, a statement issued on Monday by the China Manned SpaceEngineering Office said.

The Tiangong, or Heavenly Palace, is orbiting at an average height of about216.2 kms, the announcement noted, but did not disclose any re-entrylocation.
