Ask the day to dream of nine days, the experts of Wu Da are the popular popular science launch knowledge of the live broadcast room

At 14:22 on July 24th, the Long March 5 Yao Three Load Rockets equipped with the Tiantian Experimental Cels was launched at the Wenchang Aerospace launcher in my country, and the launch achieved a complete success. Before and after this launch, Jimu News conducted live broadcast throughout the process, attracting tens of thousands of netizens to watch. During the live broadcast, Professor Wang Shaojo, the Academy of Astronomical and Technical Research of the School of Remote Sensing Information Engineering of Wuhan University, was the live broadcast room of the Performance News, and connected with the launching site of the Wenchang launch site in Hainan.

"Every time is very nervous"

Since 2010, Professor Wang Shaoju has participated in 6 rocket launch tasks and witnessed many important moments. He said that in 2015, the whole process of researching the first "star" who launched himself as the main research and developer was very embarrassed. "What problems will I have in the process? Are these problems solved? What happens abnormal? Is there any emergency plan? Can it be automatically repaired? What should I do if there is no plan? "

At 11:06 on February 27 this year, Wang Shaoju's "Qi Xingxing No. 1" satellite developed by Wuhan University's student team as the main body participated in the Wenchang Aerospace launchers. That time he was also performing launch mission in Wenchang. After the signal was successfully connected, Gao Hang's heart fell down, crying with the students.

"Our industry is expected and recalled. Before the launch, we need to exercise multiple exercises. Each exercise process is 1: 1 arrangement. Even if it is involved in multiple launch, the ten minutes in each launch process is still very, very nervous, very, very nervous. . "Wang Shaoju said with a smile. Although he was watching" Ask the Sky "in the cloud today, he was still nervous and sweaty.

"I hope the children are watching the launch on the spot"

Wang Shaoju revealed that most of the work in the launch task is relatively difficult and boring, and generally live a two -point life of "accommodation and eating -factory test". He introduced that there are five rocket launches in my country, namely Jiuquan, Taiyuan, Xichang, Wenchang and Yantai.

Wang Shaoju believes that there are many main reasons for the landscape of this launch site. First of all, Wenchang is in Hainan Island, and Hainan as a tourist province itself is pleasant. Its natural scenery attracts many tourists. Children travel. Second, Wenchang launches is China's first coastal space launch base. The latitude is low, the shot width (within 1000 kilometers is all sea), and the sea is convenient. It is suitable for launching large space equipment. The launching ground of new types of pusher such as liquid oxygen, aviation kerosene, and many cabins in the space station have taken off from here. The third is everyone's patriotic enthusiasm. This feeling of watching large -level launch activities in person is very different from cloud viewing.

"I very much hope that the conditions for conditions can take the children to the scene to observe the rocket launch and let the children build the dream of a strong science and technology country." Wang Shaoju said that the on -site observation of the rocket launch process can truly feel the strength of the motherland's scientific and technological power. In the future, it may become the aerospace personnel of our country.

"Fat Five is an all -round improvement"

Asking the Tianjin Experimental Cels is the first experimental cabin in the construction stage of my country's space station, and it is also the largest load in my country so far. The Long March 5 Yao Three Lairer of the Long March 5 of the launching task was affectionately called "Fat Five" by netizens.

Wang Shaoju said that when it is fat, it means that its size is large, the weight of the goods that can be carried is higher, and the requirements for accuracy will be higher. Essence This time is also the first time that the "Fat Five" performs the zero window launch task, which requires it to be launched in seconds, otherwise it will not be able to send the test compartment to the specified position.

It is understood that this year's "Fat Five" will also undertake the launch task of the Mengtian experimental cabin, helping the three cabins of China Space Station to form a "T" based on the basic configuration, and complete the construction of China Space Station in the rail.

What is the effect of remote sensing

Wang Shaoju has long been engaged in the research of aerospace optical remote sensing instruments and small satellite platforms. He has won 2 first prizes of military scientific and technological progress, one second prize of national science and technology progress, and more than ten authorized invention patents. During the live broadcast, he also popularized what was "aerospace remote sensing" for netizens.

"It can be understood that the high -level camera is launched to the sky, taking pictures of the earth from the sky, and then analyzing and measured the situation on the ground through photos." Wang Shaoju said that remote sensing is measuring wind direction wind speed, environmental monitoring, agricultural reinstatement, forest grassland evaluation, etc. It has a great role in it. At present, the space -sensing image accuracy of Chinese commercial applications can reach 0.5 meters.

Wang Shaoju revealed that according to my country's space station construction plan, in the future, it will also launch Tiangtian Space Telescope. At that time, China Space Station will carry out more cutting -edge scientific research to help us understand some of the more information about some information, develop space resources, research the origin of the universe, etc.
