Shenzhou-12 carrying three astronauts docks with Tiangong space station
China successfully launched three astronauts into space on Thursday, bringing the country one step closer to completing its new space station.
The Shenzhou-12 spacecraft, or Divine Vessel, was launched on a Long March-2F carrier rocket Thursday morning, from the Jiuquan Satellite Launch Center in northwest China's Gobi Desert.
The mission sent the crew to the core module of the planned space station, called Tiangong or Heavenly Palace, which is still under construction in a low-Earth orbit.
Tiangong space station
China plans to build the world's third multi-module space station, to follow Mir and the International Space Station (ISS).[22][3]. This was dependent upon the date of OPSEK's separation from the ISS but after a statement in September 2017, the head of Roscosmos Igor Komarov said that the technical feasibility of separating the station to form OPSEK had been studied and there were now "no plans to separate the Russian segment from the ISS".[23]
The previous separate components will be integrated into a space station, arranged as:[5]
Tianhe Core Cabin Module (CCM) – based on the Tiangong-3 "space station" and analogous to the Mir Core Module. The 18.1-meter-long core module, with a maximum diameter of 4.2 meters and a launch weight of 22 tons,[24] was launched first on 29 April 2021.[25]Laboratory Cabin Module I (LCM-1 Wentian) and Laboratory Cabin Module II (LCM-2 Mengtian) – based on Tiangong-2 "space laboratory". Each laboratory module is 14.4 meters long, with the same maximum diameter and launch weight of the core module.[24]Shenzhou – crewed vesselTianzhou ("Heavenly Vessel") – a cargo craft based on Tiangong-1 that will have a maximum diameter of 3.35 m (11.0 ft) and a launch weight less than 13 t (13 long tons; 14 short tons), intended to transport supplies and experiments to the space station. The craft will have three versions: pressurized, unpressurized, and a combination of the two. It was first launched on the new Long March 7 launch vehicle from Wenchang on 20 April 2017.[26][27][28]
