On the 23rd, the Shenzhou 18 manned flight mission conducted its final regional joint training and a comprehensive system air tightness inspection. At present, rockets and spacecraft have completed power performance tests, and astronauts and various systems at the launch site have conducted full process launch exercises, all in good condition. According to Zhao Bingkun from the Jiuquan Satellite Launch Center, certain adjustments have been made to the testing launch process for this mission. Starting from the Shenzhou-18 mission, the rocket system carried out testing and launch preparation work according to the optimization plan of the standby arrow testing process, which shortened the launch cycle and improved work efficiency. Through conducting comprehensive system launch drills and regional joint exercises, various systems participated in joint debugging and testing, comprehensively simulating various technical states and work processes during launch preparation, launch, and flight, and verifying the software technology status. At present, the testing equipment is in stable condition and personnel are ready, waiting for the launch of the Shenzhou 18 manned spacecraft. The manned mission of Shenzhou-18 is the first launch mission conducted in April since the construction of the space station. This month is also the month with the highest number of strong wind and sand storms in the Jiuquan Satellite Launch Center throughout the year. The strong wind and sand storms will have adverse effects on the outdoor equipment such as the launch site's air conditioning system, non-standard tower support equipment, and power supply and distribution, and also pose certain challenges to ground support work. "We are paying attention to the changes in ground winds, dust, and high-altitude wind speeds caused by frequent activities of cold air every day." Ren Fengjie from the Meteorological Office of the Jiuquan Satellite Launch Center introduced that in order to avoid adverse effects of sandstorms on launches, the central meteorological department began task meteorological preparation work a month ago, completed the status inspection of key equipment, and added automatic meteorological stations in the surrounding key areas. A key thematic analysis of historical strong winds and dust weather was carried out based on the climate characteristics of April to improve the prediction understanding of complex weather processes. In addition, meteorological observers at the launch site analyzed and organized multiple emergency response and disposal plans by comparing the wind speed data of the launch site in April over the past decade. "We will use reliable equipment to closely monitor the evolution of surrounding meteorological data and provide timely and reliable launch site meteorological monitoring data for the task command center," said Li Zonggang, the emergency response person in charge of launch site meteorological equipment. At the same time, the launch site staff also carried out various preparations for wind and sand prevention. Platform commander Liu Yang led the personnel to use windproof cloth, sealing strips, etc. to carry out wind and sand prevention work in the tower sealing area, providing a good environment for product testing in the launch area to ensure the successful launch mission. After the Shenzhou-18 ship rocket combination arrived at the launch area, it has completed the functional and matching checks of the spacecraft and rocket, organized a full system launch drill, and will proceed with rocket propellant filling and launch according to the procedure. To ensure the safety of astronauts, the astronaut rescue team conducted a one-to-one process drill in conjunction with the mission. "While enhancing the emergency response capability and rescue level of space rescue team members, the scientific and rational nature of emergency plans has been verified, ensuring the absolute safety of astronauts," said Gao Fei, a member of the space rescue team.
