Chinas Tiangong-2 Space Lab Finishes Orbit Control

China’s Tiangong-2 space lab was adjusted to a circular orbit which is 393 kilometers above the earth’s surface on Sunday, marking the lab entering the preparation stage of docking. “This time the orbit control was to lift up the orbit of Tiangong-2, so that it can arrive in the scheduled location before the launch of Shenzhou-11 manned spacecraft,“ said Xie Jianfeng, director of the orbit office at the Aerospace Control Center. At 14:19, two times of orbit control were finished successfully.
