Full coverage: China Tiangong-2 Space Lab Launch

Tiangong-2 space lab is now orbiting the earth at about 380 kilometers high.

Initial in-orbit tests are now being carried out to make sure all equipment be working properly. Tiangong-2 will later maneuver itself to a slightly higher orbit of about 393 kilometers above Earth's surface. That is the altitude where the docking with a manned spacecraft will take place in October.

The two astronauts onboard will work in the lab for 30 days before returning to Earth. The lab will conduct 14 experiments on space science and application of space technology. The results will help prepare for longer space flight and longer space habitation.
