BEIJING, Nov. 1 (Xinhua) “Long March II F” away eight rockets will be shipped early this morning, “Shenzhou 8″ spacecraft launch , and stable operation is rail, “Temple” target vehicle for rendezvous and docking, the implementation of China’s manned space rendezvous and docking space for the first time the task to break through and verify the automatic spacecraft rendezvous and docking technology, assembly verification mode, and in space scientific experiments.

spokesman for China’s manned space program announced October 31, “Temple/Shenzhou VIII rendezvous and docking mission,” headquarters of the fifth meeting decided that Shenzhou VIII spacecraft in November aimed at at 5:58 on the 1st launch. September 29, “Temple” target vehicle was successfully launched. After two orbit, and completed in-orbit tests and orbit phase modulation platform, the current Temple One is a height of about 343 km near circular orbit on the run, waiting with the Shenzhou VIII spacecraft rendezvous and docking.

“Shenzhou 8″ spaceship manned spacecraft improved, follow-entry capsule, Tui Jincang and orbital three-compartment structure, length of 9 meters, the maximum diameter of 2.8 m cabin, take-off mass 8082 kg. Increase of microwave radar, laser radar, CCD sensor measuring equipment such as rendezvous and docking mechanism active, with automatic and manual rendezvous and docking with the separation. Docking mechanism using inverted style guide plate allogeneic peripheral-type configuration with the configuration, can be formed after docking the astronauts 0.8m transfer channels.

launch Shenzhou VIII spacecraft’s Long March II F rocket is away eight in the original Long March II F rocket, based on the booster, control systems, fault detection processing system has been improved to improve the reliability and orbit accuracy. Rocket for about 58 meters, take-off mass of about 497,000 kg, carrying capacity is not less than 8130 kg.

rendezvous and docking control communication network consists of two days chain One relay satellites, 16 ground-based monitoring stations at home and abroad, 3 tracking ship, as well as Beijing and Xi’an, the flight control center monitoring and control centers.

Shenzhou VIII spacecraft return to the main landing field Sunit Right Banner of Inner Mongolia Autonomous Region is located in Xia Long Prairie ancient wood.

Detailed procedures for flight procedures

It is issued by the Office of China’s manned space program, the first rendezvous and docking of unmanned automatic rendezvous and docking experiments, docking target One vehicle for the Temple, tracking aircraft for the Shenzhou VIII spacecraft. Rendezvous and docking flight distance guide is divided into sections, self-control section, butt section, combination and separation of evacuation flight segment segment.

long-range guidance section from the Shenzhou VIII spacecraft orbit after, the ground control communications systems, guided by the five Shenzhou VIII spacecraft orbit, transfer orbit from the initial 330 one thousand m nearly circular orbit, the spacecraft away from the Temple One goal after about 52 km and below, with Temple One goal of the empty aircraft to establish a stable communication link to start autonomous navigation.

own experience to find the control section, close and shift closer to the three stages, Shenzhou VIII spacecraft rendezvous and docking by the measuring equipment, autonomous navigation to the target aircraft with Temple One touch, self-control flight of about 144 minutes .

docking contacts section starting from the docking mechanism, completed in 15 minutes to capture, buffer, four narrow and locking process, and ultimately two vehicle rigid connections to form a combination.

combination flight segment is responsible for the Temple One goal of aircraft flight control assembly, Shenzhou VIII spacecraft docked state. Combination of flight about 12 days, choose a second rendezvous and docking. Docking mechanism is unlocked, the two aircraft separation, Shenzhou VIII spacecraft withdrawal from the Temple to 140 meters One goal of aircraft parking, docking procedures in accordance with a second rendezvous and docking, re-form combinations.

combination to continue the flight two days later, into the evacuated section of the separation, the two spacecraft separated again, Shenzhou VIII spacecraft to withdraw from Temple One goal of aircraft a safe distance from 5 kilometers away, rendezvous and docking end of the trial.

Later, Shenzhou VIII spacecraft scheduled return flight procedures, the capsule back to the main landing field; Temple One goal of aircraft rose to a height of about 370 one thousand meters orbit autonomous flight orbit, waiting for the next rendezvous and docking .

scheduling according to the rendezvous and docking mission, in 2012 launched the Shenzhou 9 and Shenzhou-10 spacecraft, and then twice rendezvous and docking. Which is manned spacecraft Shenzhou 九号, Shenzhou VIII mission will be based on assessment of decision-making, implementation of the Shenzhou-10 spacecraft manned flight.

Through this mission, break, and of space rendezvous and docking technology will enable the level of China’s manned space technology has leapt to a new level.

“Shenzhou” Flying History

1999 年 20 to 21 November, China successfully launched the Shenzhou spacecraft conducted its first unmanned test flight The main purpose is to assess the performance and reliability of launch vehicles, and to verify the spacecraft to return control of key technologies and system design is correct.

2001 年 10 to 16 January, China successfully launched Shenzhou II unmanned spacecraft for the second flight test, the main purpose of the project and the overall system to run from the launch, return, leave track the entire process to conduct a comprehensive assessment, to further test the overall technical program and the correctness of the systems and technology solutions matching.

2002 年 March 25 to April 1, December 30, 2002 to January 6, 2003, China has successfully launched the Shenzhou III, the third spacecraft Shenzhou IV, the first four unmanned test flights, the rocket to escape, the spacecraft emergency rescue functions are real state, manned flight status and flight technical consistency.

2003 年 15 to 16 October, China successfully conducted the first manned space flight, astronaut Yang Liwei, China’s manned spacecraft Shenzhou V take to run 14 laps in space, lasted 21 hours, 23 minutes, successful completion of the scheduled operation mission, the safe return of the main landing field.

2005 年 12 to 17 October, China successfully conducted its second manned space mission, Chinese astronauts Fei Long, Nie Haisheng take the Shenzhou VI manned spacecraft in space to run 76 laps, which lasted 4 days 19 hours 33 minutes, over many days to achieve the safe return of the main flight and landing field.

2008 年 25 to 28 September, China’s successful Shenzhou VII manned space flight, astronauts Zhai Zhigang and Liu Boming, Jing Haipeng, 46 laps in space flight, which lasted 68 hours, Zhai Zhigang was wearing China developed the “Flying” extravehicular spacesuit, to achieve China’s first space astronaut extravehicular activity.
