Experts from the agency, the Chinese Academy of Sciences and China Aerospace Science and Technology Corp reviewed the design, construction and test reports on the space station's Tianhe core module, the Tianzhou 2 cargo spaceship and the core scientific capsule, the agency said in a statement on Thursday.

Sources close to the agency said the components will be transported to the Wenchang Space Launch Center on Hainan Island and launched into space in coming months.

China will start assembling its first space station this year, according to government plans. Major stages of the program include the Long March 5B flight this spring, tasked with transporting the station's core capsule into a low-Earth orbit; two astronaut missions to prepare the capsule for other components; and two robotic cargo flights to deliver supplies.

The core capsule, Tianhe, or Harmony of Heavens, will have three parts - a connecting section, a life-support and control section and a resources section.

It will be equipped with three docking hatches for manned and cargo spacecraft, and two berthing locations to connect with space laboratories. There will also be a hatch to launch astronauts' extravehicular activities.

The core module will be 16.6-meters long, with a diameter of 4.2 meters. It will be central to the space station's operations, given that astronauts will live there and control the entire station from it. The module will also be capable of hosting scientific experiments.

Once it becomes fully operational around 2022, the multimodule Chinese space station - Tiangong, or Heavenly Palace - will be comprised of three main components; the Tianhe capsule and two space labs, with a combined weight of more than 90 metric tons.
