The whole system is ready for the launch of the Tianzhou-3 cargo spacecraft

The Tianzhou-3 cargo spacecraft will be launched at the Wenchang Space Launch Site in the near future. At present, the mission’s systems have been prepared for launch. CCTV reporter Wang Xiaodan: This is the test launch hall of the Wenchang Space Launch Site. The staff of each system is conducting the last joint exercise of the entire flight area before launch to check the status of the measurement and control communication system and the coordination between the various sub-systems. Cooperate ability, and inspect, confirm and solidify the technical status of the whole flight area. This launch mission will be launched by the Long March 7 Yaosi carrier rocket on board the Tianzhou-3 cargo spacecraft into orbit. After the Tianzhou-3 ship-and-arrow assembly was transferred to the launch area on the 16th, preparations such as testing and inspection of various systems and general drills of the entire system have been carried out successively.

Mao Wanbiao, deputy director of the Xichang Satellite Launch Center: Judging from the joint training situation in the entire flight area, the measurement and control equipment in the entire flight area is in good condition, and the communication line is unblocked, and it has the conditions for refilling and launching. It should be said that our equipment and facilities are in good condition, including the cargo spacecraft system, the astronaut system, the launch site system, and the rocket system. The entire test project has been completed, the test status is qualified, and the product quality meets the requirements. According to the latest meteorological consultation, the meteorological conditions meet the launch requirements. The rocket system has entered the pre-launch state preparation stage. The replacement of the tank and the air tightness inspection of the entire system have been carried out, and the control system and measurement system on the rocket have been checked for function.

Ma Zhonghui, deputy chief designer of the Long March 7 rocket of the First Academy of the Aerospace Science and Technology Group: reviewed and confirmed the status of the cargo spacecraft launched by this mission and the rocket, and made improvements to the rocket to enhance the robustness of the rocket; another On the one hand, the pre-launch plan and the level of refinement of the interpretation have been optimized for the problems that occurred in the last shot before the launch. At present, all functional inspections have been completed, and the conditions for launch and ignition have been completed.

The Tianzhou-3 cargo spacecraft launched this time is loaded with nearly 6 tons of supplies, and will carry out autonomous and rapid rendezvous and docking with the core cabin of the space station to prepare for the follow-up Shenzhou 13 flight mission. At present, the Tianzhou-2 in space has completed its orbit, and the core module of the space station is waiting for the arrival of Tianzhou-3. Lei Jianyu, deputy chief designer of the Tianzhou-3 cargo spacecraft system of the Fifth Academy of Aerospace Science and Technology Group: At present, the Tianzhou-3 cargo spacecraft system has completed the comprehensive test of the vertical state of the launch area, the cargo loading before the launch, and the launch state setting. It is in good condition and has the conditions for launch.
