Tiangong 2 ( Chinese 天宮 二號 / 天宫 二号 , Pinyin Tiāngōng Èrhào - "Heavenly Palace 2") was the second space station of the People's Republic of China after Tiangong 1 . It was in space from September 15, 2016 to July 19, 2019. A new, larger Chinese space station should be built from 2020 at the earliest .
construction
The fuselage of the space station was 10.4 meters long and consisted of a crew and a service module, both cylindrical , which were connected by a 1.1 meter long transition.
The crew module was 5 meters long and 3.35 meters in diameter. Among other things, it contained devices for scientific experiments and controls for the space station. It also had a coupling adapter for Shenzhou and Tianzhou spaceships. Two windows gave the crew a view of space and the earth.
The service module was approximately 3.3 meters long with a diameter of 2.5 meters. In particular, it contained the station's propulsion system, which had been taken over from the Shenzhou spacecraft. Two solar modules for power supply were attached outside . The oxygen and water supplies necessary for life support were located in the transition between the two modules.
use
Tiangong 2 was placed into orbit on September 15, 2016 by a Long March 2F rocket . The launch took place at 16:04 CEST from the Jiuquan Cosmodrome .
On October 18, 2016 , the Shenzhou 11 spacecraft docked . The Chinese Taikonauts Jing Haipeng and Chen Dong formed the first and only crew of the space station. They stayed on board for 29 days, setting a new Chinese record.
The unmanned space freighter Tianzhou-1 was docked from April 22 to June 21, 2017 . Among other things, the filling of the space station's fuel tanks was tested. Another docking of the same spaceship took place on September 12, 2017.
In July 2019, Tiangong-2 was brought down in a controlled manner. After several targeted orbit lowering maneuvers, the space station entered the earth's atmosphere on July 19, 2019 at 3:06 p.m. CEST . Most of it burned up from the heat during and after reentry ; According to the Chinese authorities, smaller remains fell in the South Pacific .
