On the evening of February 23, close to the Lantern Festival, the Long March 5 Yao-7 carrier rocket took off from the Wenchang Cosmodrome and flew into space. This Spring Festival, multiple missions in the launch site were carried out in parallel, and multi-satellite and multi-arrow tests were organized and carried out as planned. During this period, the scientific and technological personnel of the Technical Department of Xichang Satellite Launch Center laid a solid foundation for the success of the mission with perseverance and dedication.
The weather in the mission launch window is good, and the launch meteorological conditions are met. Fan Jing, an engineer of the meteorological system at the launch site, said that Wenchang is in the dry season during the mission, and it is necessary to pay attention to the evolution of cold air and high-altitude wind fields. During this period, he and his colleagues continued to strengthen the detection frequency and accuracy of the high-altitude wind field according to the climatic characteristics of the high-altitude wind field in the dry season, and paid close attention to the shear and weather changes of the high-altitude wind field, so as to provide meteorological support for the successful launch.
This Spring Festival, the astronauts at the Wenchang Cosmodrome are particularly busy. Since the launch of the mission, they have stuck to their posts and provided decision-making basis for key nodes such as vertical rocket transfer, fuel filling, and launch window.
Watching the "Fat Five" rise from the ground in the roar, Zhang Qing, senior engineer of the cryogenic filling system, smiled. In order to ensure the reliability of the equipment, the system where he is located must maintain the equipment daily to ensure the normal state of the equipment. The transformation of the equipment should also be carried out simultaneously, and various technical solutions should also be designed. In 2013, when Zhang Qing first entered the Wenchang launch site, he took on the heavy responsibility of designing and building the low-temperature refueling system and gas supply system at the launch site. There was no ready-made experience to refer to, so he "gnawed" the drawings and "chewed" the plan, led everyone to overcome a number of technical problems, and designed a set of refueling processes for the brand-new launch site and low-temperature large rocket.
Before the rocket launch, Zhang Qing was always the busiest time, starting with the injection of cryogenic propellant, monitoring the refueling status until launch, and sometimes, he and his colleagues had to stay up all night, "but until the moment the success was announced, all the hard work was worth it." ”
