During October 12-17, 2005, the Shenzhou VI manned space flight task under China manned Space Program was successfully implemented. The main purpose of this task is to master the technology relating to "multi-person and multi-day" orbit flight of manned spaceship, carry out the manned space-related scientific experiments, verify the function and performance of various systems, further improve the safety and reliability, accumulate the experience in prolonged stay in space (working and living), and create conditions and lay foundation for the sustainable development of the China Manned Space Program. Riding the Shenzhou VI spaceship, the astronauts Fei Junlong and Nie Haisheng successfully completed the first "multi-person and multi-day" manned space flight test of China. The preset objective of this task, which says "successful launching, normal operation, safe return, and healthy astronauts," was achieved, which indicates that China has made another major achievement in the manned spaceflight technologies.

At 9:09 a.m. on October 12, 2005, the Shenzhou VI spaceship, together with the astronauts Fei Junlong and Nie Haisheng, was launched by the LongMarch 2F carrier rocket from Jiuquan Launch Center. At 120 seconds after taking-off the escape tower separated; at 137 seconds the boosters separated; at 159 seconds the first stage separated and the second stage ignited; at 200 seconds fairing separated; at 461 seconds the second stage main engine powered off; at 584 seconds spaceship separated from the rocket and entered an elliptical orbit with inclination of 42.4o, the perigee height of 200km and the apogee height of 346.8 km. In the orbit，the spaceship set up an in-orbit operating mode and unfolded the solar cell arrays on the propulsion module to point the sun. When the flight began with the fifth circle, the spaceship implemented orbital transfer to the 343km circular orbit.

In the course of the task, the ground tracking & control center understood the physical, living and working conditions of the astronauts on the basis of the physiological parameters obtained through remote sensing, the image transmitted back to the ground and the audio communication. In the course of flight, the two astronauts monitored the implementation of important commands and the operating conditions of spaceship, reported the relevant situations to the ground, re-sent the relevant commands, carried out the in-orbit anti-interference test, the space-ground communication test and the operation of camera and maritime satellites, and implemented a series of key control including posture adjustment, separation between orbital module and re-entry module, braking and ignition. At 4:33 on October 17, 2005, after flying around the Earth for 76 circles, the re-entry module of the spaceship safely landed at the primary landing site, and the astronauts Fei Junlong and Nie Haisheng successfully completed the manned flight task. The orbital module remained in the orbit for about half a year, carrying out space-related scientific experiments and application tests.
