On November 20th and 21st, 1999, the flight test of the first "Shenzhou" unmanned test spacecraft of China's manned space project was obtained A complete success. From the beginning of 2001 to the end of 2002, the Shenzhou 2-4 unmanned test spacecraft were successively developed and successfully launched, obtaining valuable test data and laying a solid foundation for the implementation of manned spaceflight. The Shenzhou-5 spacecraft is my country's first manned spacecraft developed on the basis of an unmanned spacecraft. It carries one astronaut and operates in orbit for one day. During the entire flight, the astronauts will be provided with necessary living and working conditions, while the astronauts' physiological data and television images will be sent to the ground to ensure the astronauts' safe return.

The spacecraft consists of an orbital module, a return module, a propulsion module and additional sections, with a total length of 8860mm and a total weight of 7840kg. The spacecraft's manual control function and environmental control and life support subsystems provide guarantees for the safety of astronauts.

The spacecraft was launched by the Long March-2f carrier rocket to an initial orbit with a perigee of 200km, apogee of 350km, and an inclination of 42.4°. After performing orbit changes, it entered a circular orbit of 343km. The spacecraft circled the earth 14 times and landed in a predetermined area.

The manned space flight of the Shenzhou-5 spacecraft has realized the Chinese nation's millennium desire to fly into the sky. It is a high degree of cohesion of the wisdom and spirit of the Chinese nation and a new milestone for China's aerospace industry in the new century.

"Shenzhou" No. 6 launch rocket chief designer Liu Zhusheng accepted this When interviewed by a reporter from the newspaper, he said that the production and manufacturing of various systems of the "Long March 2F" carrier rocket responsible for the launch mission of the "Shenzhou" 6 spacecraft has been fully launched. Up to now, all production of the launch rocket has been progressing steadily as planned.

According to Liu Zhusheng, all the equipment of the rocket system will be "complete" by the end of this year. Comprehensive experiments and matching experiments of each system will be carried out early next year. If the work goes smoothly, the "Shenzhou" six will be launched. The rocket system will be shipped from the factory in June or July next year.

Liu Zhusheng, chief designer of the "Shenzhou VI" launch vehicle, accepted an exclusive interview with this newspaper to explain the rocket system in detail

Following the successful first manned flight of my country's "Shenzhou 5", " The Shenzhou-6 space project is already underway. In order to push the Chinese people's "flying dream" to a new level, all preparations before the launch of "Shenzhou" 6 have been fully launched. As the "helper" of the spacecraft, the "Long March 2F" carrier rocket will once again assume the important task of sending "Shenzhou 6" into space and into orbit. Although the power carriers of the "Shenzhou 5" and "Shenzhou 6" spacecraft are the same type of rocket, the rocket system for launching the "Shenzhou" 6 is "different." Yesterday, rocket system chief designer Liu Zhusheng accepted an exclusive interview with our reporter to explain in detail the focus of the Shenzhou 6 rocket.

Focus 1: The rocket will be delivered by the end of the year and the equipment will be fully configured

Liu Zhusheng, the chief designer of the rocket system responsible for the launch of the "Shenzhou" 6, revealed to reporters the rocket that launched the "Shenzhou" 6 Timetable for system preparation. According to Liu Zhusheng, all equipment of the rocket system must be "delivered on schedule" by the end of 2004, and each set of instruments must be fully configured to prepare for the subsequent comprehensive experiment of the rocket system early next year. Liu Zhusheng said that in the comprehensive experiment stage, each component of the rocket must be tested in its own laboratory. The purpose is to ensure that the entire rocket meets the standards. After passing the test, the various systems will "join together" and conduct matching experiments.
