BEIJING, April 1 (Xinhua) -- Tiangong-1, China's first space lab, will re-enter the Earth's atmosphere on April 2, China Manned Space Engineering Office (CMSEO) said on Sunday.

Tiangong-1 orbited at an average altitude of 167.6 kilometers on Sunday.

The space lab will mostly be burnt up in the atmosphere and it's highly unlikely to cause any damage on the ground.

Tiangong-1 was launched on Sept. 29, 2011 and ended service in March 2016 after completing its mission.

It has docked with Shenzhou-8, Shenzhou-9, and Shenzhou-10 spacecraft and undertaken a series of tasks, making important contributions to China's manned space cause.
