The construction of the space station has entered a crucial stage, said the CMSA, noting that this year will see several space missions including the launch of the station's core module, cargo replenishment, and a manned flight, which will be carried out one after another.

China aims to complete the construction of its space station by around 2022. During the construction, China plans to launch four Shenzhou manned spaceships and four Tianzhou cargo spacecraft to transport astronauts and supplement materials.

The Long March-5B Y2 rocket, which will launch the core module, has been safely transported to the Wenchang Spacecraft Launch Site in Hainan province. The core module is scheduled to be launched in the first half of this year.

China plans to launch the core module of its space station before the end of June, starting the construction of the nation's largest space-based asset, the China Manned Space Agency said.

The 20-metric-ton core module and the Long March 5B heavy-lift carrier rocket tasked with launching it have arrived at the Wenchang Space Launch Center in Hainan province, the agency said on Thursday morning, adding that four groups of astronauts have been selected for the space station's construction and are undergoing training.

It said China is determined to open the station to international cooperation in science and technology. Chinese scientists and their counterparts from the United Nations have selected the first batch of scientific experiments proposed by foreign researchers that will be carried out in the station. They are currently working on the implementation of the cooperative programs, the agency said.

The agency said it is also considering plans for China's manned lunar exploration program.

China's most sophisticated space endeavor, the multimodule space station, named Tiangong, or Heavenly Palace, will be mainly composed of three components-a core module attached to two space laboratories-with a combined weight of more than 90 tons.

The core module, named Tianhe, or Harmony of Heavens, is 16.6 meters long and has a diameter of 4.2 meters. It has three parts-a connecting section, a life-support and control section and a resources section.

It will be central to the space station's operations, given that astronauts will live there and control the entire station from inside.

The entire station is expected to become fully operational next year and is set to operate for about 15 years, program planners have said.
