CTOnews.com March 12 news, CTOnews.com learned from the China Manned Space Engineering Office, China's space station has been fully completed, China's manned space project "three-step" development strategy has become a reality from conception. At present, the space station complex is operating stably in orbit, and the Shenzhou XV astronauts are in good condition and are scheduled to return to the ground in June this year.

At present, the project has fully entered a new stage of space station application and development. At present, Tianzhou-6 cargo spacecraft has completed relevant work and transported to Wenchang Space Launch Site. It is planned to launch in May this year. Astronaut crews for two manned flights have been selected and mission training is ongoing.

In the new stage, China's manned space program will carry out two Shenzhou manned spacecraft launches and one to two Tianzhou cargo spacecraft launches every year. The year 2023 is the first year when China's space station has entered the application and development stage. It is planned to launch two manned spacecraft, Shenzhou 16 and Shenzhou 17, and one cargo spacecraft, Tianzhou 6.

It is expected that on the afternoon of May 10,2023, the "Long March 7" remote 7 launch vehicle carrying the "Tianzhou 6" cargo spacecraft will be launched from Station 201 of Hainan Wenchang Launch Site. After the spacecraft is launched, it will be docked to the rearward port of the "Tianhe" core module in a rapid rendezvous and docking mode. This launch is the first launch of China's manned space project in 2023. It will send "grain and grass" and "baggage" for the "God 16" mission first, and undertake the important task of starting the new stage of China's manned space project.

Starting from "Tianzhou 6,""Tianzhou" series spacecraft entered a new batch production stage, and six spacecraft from "Tianzhou 6" to "Tianzhou 11" were arranged for development and production. At this stage, the "Tianzhou" spacecraft has been upgraded systematically, the cargo compartment has been greatly improved, the cargo transportation capacity of the capsule has been greatly enhanced, and the materials provided to the astronauts will be able to last longer. Compared with the previous batch, the "Tianzhou-6" spacecraft increased the volume of the sealed cabin by about 500 kilograms, increasing the capacity from 6.9 tons to about 7.4 tons. Based on the increase in capacity, the launch density of the space station mission "Tianzhou" cargo spacecraft was adjusted from 2 times/ 1 year to 3 times/ 2 years accordingly.

In this trip, the "Tianzhou-6" mission mainly includes the expendable materials such as the astronaut residence materials and extravehicular clothing; the maintenance spare parts and propellants to ensure the safe operation of the platform, various loads and samples of the application mission; and the descending orbital wastes.
