China’s manned space engineering office revealed yesterday that according to the plan, Tiangong No. 2 Space Laboratory has completed all expansion tests. It is scheduled to be controlled off-track and re-enter the atmosphere on July 19, 2019 Beijing time. A small amount of debris will fall into the air. The South Pacific is scheduled to be safely seaed (160 degrees to 90 degrees west longitude and 30 degrees to 45 degrees south latitude).
The Tiangong No. 2 Space Laboratory was developed on the basis of the Tiangong No. 1 backup target aircraft. It consists of a test cabin and a resource compartment. The total length is 10.4 meters, the maximum diameter of the cabin is 3.35 meters, and the span of the solar sail is about 18.4. The meter has a take-off weight of about 8.6 tons. It has important functions such as rendezvous and docking with the Shenzhou manned spacecraft and the Tianzhou cargo spacecraft, the implementation of propellant on-orbit addition, space science experiments and technical tests.
Tiangong No. 2 Space Laboratory was launched into orbit on September 15, 2016. It has been designed for orbital life of 2 years. Up to now, it has been flying in orbit for more than 1000 days. The platform and load function are normal and in good condition, and the controlled re-entry into the atmosphere. Preparations are progressing steadily and steadily as scheduled.
