China's space lab Tiangong-2 has entered an in-orbit test track, the Beijing Aerospace Control Center said Friday.
"Tiangong-2 is in good condition currently, and its sub-systems are operating smoothly," said Chen Xianfeng, an expert with the center.
After entering the in-orbit test track, ground operators will test the stability of its sub-systems and carry out a series of space science experiments.
China successfully launched Tiangong-2 from Jiuquan Satellite Launch Center in the northwest Gobi desert late Thursday.
