LONDON reporter, Qiu Yingqiong, reported on June 24: noon today, the Shenzhou No. 9 Temple One () will be a short separation, a second rendezvous and docking. On the 18th, the first automatic rendezvous and docking, the second will take manual control of the astronauts. Why, after the success of the automated docking also verify that the manual Both what is different Why conduct a manual rendezvous and docking Since an automated manner, the successful completion of the space docking of the aircraft, why should we allow God to nine manual docking Manned spaceflight chief designer Zhou Jianping has said from the perspective of the development of the world's manned space rendezvous and docking should be covered by the automatic and manual two aspects, both as a backup, are indispensable. Automatic and manual techniques have been verified, is to achieve a complete rendezvous and docking. From the rendezvous and docking situation of the world, the success rate of manual rendezvous and docking. This is due to the automatic docking is a program control in response to the rapid, precise control, but once outside of the strategic plan, the automated system becomes powerless. When the disposal of an accident situation, the astronauts can play it by ear. In addition, the manual rendezvous and docking, can further verify the reliability and security of the domestic docking mechanism. On the spacecraft and the Temple of the docking mechanism is by far the most complex space agencies. Rendezvous and docking validation Previously, its programs and product reliability to meet the mission requirements. Manual rendezvous and docking What's the difference Aerospace science experts Tao Jianzhong told reporters in the rendezvous and docking, the manual part is the rendezvous, docking is still the main system automatically. Manual rendezvous and docking, the astronauts just have to do two things. "Tao Jianzhong said, the first astronaut to be dimming, they shoot the outside of the television cameras on the spacecraft, so the spacecraft on the cross target and Temple "Cross target overlap, so you can achieve precise position and attitude of the rendezvous and docking. However, dimming in the case of the space environment can not be too bright or too dark, or astronauts easy tone are not allowed. The second thing is to adjust the spacecraft and the attitude of the Temple in the rendezvous and docking, when the astronauts just two joysticks on the spacecraft to adjust the pan position and attitude, to be calibrated. Seemingly simple two-step process, but in the vastness of space has become extremely difficult. Tao Jianzhong said the rendezvous and docking, the astronauts to accurately determine the relative position of the two spacecraft, attitude and translation of two handles, spacecraft attitude control, forward speed and direction, eye-hand coordination, operating fine, and psychological qualities demanding. Therefore, in order to make the manual rendezvous and docking foolproof, the astronauts on the ground thousands of times in training. It is reported that the rendezvous and docking missions, Liu Wang, training has reached 1500. Instrument data alone optical display to be able to operate.
