China\'s first space lab module Tiangong-1 completed its second obital transfer Friday afternoon BJT with its apogee altitude rising from 200 kilometers to 362 kilometers. The obital maneuver was executed under the direction of the Beijing Aerospace Flight Control Center as the module made its 13th circle around the earth. The Space lab finished its first obital transfer on Friday as well. The Control Center will now start obital tests which will last for about one week. Tiangong-1 will orbit the earth for about one month waiting the arrival of the Shenzhou-VIII unmanned spacecraft. Once the two vehicles are in orbit, they will conduct their first space docking.
