　　China News Service, Beijing, November 29th (Ma Shuisha) On November 29th, the Shenzhou 15 manned spacecraft was lifted steadily by the Long March 2F carrier rocket, carrying 3 astronauts, from the Jiuquan Satellite The launch center soared into space.

This is the last manned spacecraft launched during the construction phase of China's space station.

　　In late November, the Jiuquan Satellite Launch Center was already very cold, with the lowest temperature reaching minus 20 degrees Celsius.

Previously, only two unmanned spacecraft, Shenzhou 1 and Shenzhou 4, were launched after mid-November.

The Shenzhou 15 mission is the first manned mission implemented in such a low temperature environment.

　　Facing this new challenge, the test team confirmed the guarantee of the air supply equipment in the two sets of fairings configured at the base, and agreed to supply air according to the upper temperature limit.

At the same time, in view of the possible failure of the low air supply temperature in the waiting section, the test team formulated a risk control plan, and turned on the electric temperature adjustment on the ground of the propulsion storage tank according to the situation, so as to ensure that the temperature of the propellant in the return cabin and the propulsion cabin meets the launch requirements. .

　　It is reported that the Shenzhou 15 mission is China's 10th manned spaceflight mission.

As the "boat of life" for astronauts to go back and forth between heaven and earth, the Shenzhou series of manned spacecraft consists of an orbital module, a return module and a propulsion module. It is the spacecraft with the most stringent reliability and safety requirements in China.

Since the establishment and implementation of China's manned space program, China has successfully launched 15 Shenzhou spacecraft, successfully sent 16 astronauts and 26 people into space, and the mission success rate is 100%.

　　In the follow-up, the Shenzhou 15 spacecraft will conduct forward rendezvous and docking with the space station assembly that has formed the basic configuration of "T".

Afterwards, the three astronauts will enter the space station and meet with the astronauts of Shenzhou XIV.
