On the morning of the 9th, the Tianzhou-6 cargo spacecraft mission organized a pre launch system wide joint exercise. At present, all systems are ready for launch. The Tianzhou-6 mission is the first flight mission in the application and development phase of China's space station. In response to the significant changes in the technical status of the "upgraded" cargo spacecraft and the shortening of the rocket testing cycle from 27 days to 25 days, scientific and technological personnel have worked under pressure, continuously fought, and persevered. They have organized and completed the testing and refueling of the technical area of the Tianzhou-6 cargo spacecraft, the vertical final assembly testing of the Long March 7 carrier rocket, the joint testing of ships and rockets, and the vertical transfer of the combination. During the joint training, the participating systems are tightly organized and closely coordinated to ensure that all procedures are carried out in an orderly manner. "This joint exercise is a comprehensive simulation exercise with the largest number of participating systems before launch and the last before launch," said Zhong Wen'an, chief engineer of Xichang Satellite Launch Center. In response to the climate characteristics of frequent showers during the mission, the launch site meteorological system has strengthened meteorological monitoring and consultation density to ensure accurate meteorological forecasts for the launch date. At present, the rocket, spacecraft, and launch site systems are in good condition. We have confidence and determination to complete the launch mission and ensure that the 'express' mission of Tianzhou-6 will be achieved, "said Zhong Wen'an. (New News Agency)
