Development of China’s aerospace industry

, Shenzhou V: Target manned flight, launch during the day. Different from the launch time of previous Shenzhou series, Shenzhou 5 chose daytime. In the past, the launch times of Shenzhou spacecraft were usually in the early morning and midnight. According to relevant experts, space launch requires determining a certain time period of the day as the opportunity to launch the spacecraft. This time period is called the "launch window." It turns out that the launch window of the Shenzhou series was chosen at night, mainly to make it easier for the optical tracking measuring instrument on the ground to capture the target when the spacecraft was launched into space. The Shenzhou 5 chose to launch during the day, mainly because the temperature during the day would be conducive to the work of the launch personnel, and it would also be easy to fully protect the personal safety of the astronauts when unexpected situations occur.

3. Shenzhou VI: "Shenzhou 5" has only one passenger, Yang Liwei, but on October 12, the space welcomed two guests - Fei Junlong, the two astronauts of China's "Shenzhou 6" and Nie Haisheng. The increase in the number of people has brought varying degrees of changes to all aspects of the flight mission and to various engineering systems. For example, the equipment carried has to be doubled, there are problems with coordination between the two astronauts, etc. Two-person flight can more comprehensively assess the performance of the spacecraft and other engineering systems than single-person flight.

4. Shenzhou VII: The "Shenzhou VII" flight will also conduct a test of a space relay terminal. The completion of this task will lay a good foundation for our country to establish a space and earth measurement and control network, greatly improve the coverage and efficiency of the measurement and control network, and lay a better foundation for future manned spaceflight activities such as rendezvous and docking that require higher measurement and control coverage. .

At 6:30:07 on November 20, 1999, my country's first test spacecraft "Shenzhou" 1 successfully launched. China became the third country in the world to have manned spaceflight after the United States and Russia. The country of technology. After completing 21 hours of space science experiments, it successfully landed at 3:41 on the 21st. The successful launch and recovery of the "Shenzhou" experimental spacecraft has become another milestone in my country's aerospace history. The date of success was November 21, 1999, only one month and nine days before the end of the year. Among the astronauts who have been counting down the calendar every day for seven years, many just want to have a good sleep. But even such a simple wish is an unattainable luxury for many people. Amid the new beats of war drums, "Shenzhou-2" began to take off again.

The Chinese astronauts who are driving the rumble skycar into space must race against time for the ideal of a nation!
