in 1969, the United States for the first time astronauts to the moon, the human dream has long been landed on the moon ideal. Accordingly view, on the space planning and technology, today compared with the United States, there is a considerable gap.

the Hong Kong Economic Journal “on June 18, the original title:” God nine military space June 16 18 37 points 21 seconds, the “Shenzhou on the 9th The spacecraft carrying three astronauts flying. “Temple” target aircraft is 343 km away to the intersection on the trail standards, waiting the arrival of the “Shenzhou No. 9″.
at half 17 at 1, the “divine nine” spacecraft orbit for the first time this day it will be the fifth orbit to catch up with the “One Temple”, followed by the spacecraft to enter the “One Temple behind the straight-line distance of 52 km, a vertical distance of 50 km track position.
Simply put, this “God nine spacecraft during the execution of the mission are as follows:” Long March II F “away nine ignition of the rocket launch, the flight of about 585 seconds, the ship separated from the rocket, the spacecraft entered the perigee of about 200 km, an apogee of about 330 km initial orbit, will complete the automatic rendezvous and docking with the “One Temple”, to form a combination, the three astronauts to enter the “One Temple” JEM to conduct scientific experiments, technology testing, exercise and rest
subsequent separation of aircraft, another independent control by the astronauts in the spacecraft and the “One Temple” to achieve the manual rendezvous and docking, formation of the assembly again. Astronauts after the completion of scheduled tasks, the spacecraft again separated with the “One Temple” to return to Earth established the landing site, “Temple One” go to the long-term orbit.
return cabin real-time monitoring of the orbit of the three stages of theaerospace engineering
three astronauts in the spacecraft, they have clothes from the white cabin pressure to wear a blue space inside the overalls. Spacecraft into orbit, they call with the ground staff for the first time.
within a few days “divine nine” spaceship “One Temple” rendezvous and docking, which is China’s first manned space rendezvous and docking manually, the critical step in the China Manned Space Engineering step.
in January 1992, decision-making a formal decision to start a costly manned space project, code-named the “921 Project”. Loading aerospace engineering is divided into three stages to implement.
the first phase to launch a manned spacecraft, the spacecraft into orbit, and the ship safely back to the ground. 1999 launch Shenzhou unmanned spacecraft, Shenzhou V, single spacecraft, launched in 2003, double spacecraft Shenzhou VI was launched in 2005.

first end.
the secondstage, the astronauts will complete the extravehicular activities, and to achieve the rendezvous and docking, the establishment of laboratories, laboratory and in the short term care, laboratory long-term autonomous flight in space orbit.
2007, China launched the Shenzhou VII many spacecraft, the completion of extravehicular space walk; September 29, 2011, China launched the “One Temple”, to stay in the intended orbit; 30 three days after eight unmanned spacecraft in God as the target aircraft launch and success with the “One Temple” twice to complete the automatic docking, followed by separation of the return capsule returned to Earth.
is the God of eight unmanned spacecraft and the successful docking of the “One Temple”, laid the basis of this “divine nine” spacecraft carry out its mission of “Divine nine” the launch will be the first manned space rendezvous and docking with the “One Temple”, which means that China will be completed thoroughly and validation of the docking of space technology, and provide key technologies to achieve long-term manned Skylab protection.
the third stage, China will build long-term manned, short-term self-flying 20-ton space station. Chinese space station project completion of the system after a complete package, you can solve a series of applications.
God nine four task difficulty
, according to China’s aerospace sector, “God 9″ spaceship task there are four characteristics of difficulty: the first implementation of the manual rendezvous and docking, aerospace member’s first visit to the in-orbit spacecraft, the first space flight of the female astronauts, the first days of manned flight in orbit.
few decades ago, the United States and Russia has long manned space rendezvous and docking. Striking, 8 2011 launch of the Shenzhou first automatic rendezvous and docking with the “One Temple”, why should the manual docking? This is because the automated docking unexpected situation, the docking can be controlled by hand to solve the problem. The human brain, after all, is more reliable than a computer, a successful manual rendezvous and docking requirements; two high-speed flight collision, damage to the docking mechanism, the “Temple One” no longer be able to docking.
manual docking both astronauts operating the accuracy and sensitivity to high demand, but also the adaptability of the spacecraft control system and a higher requirement. Astronauts to operate inside the space is small, but also by the strong light interference, the first manual rendezvous and docking technology will consume a lot of physical strength. The astronauts operating standards is a challenge.
“God nine spacecraft is equivalent to the former Soviet Union, the United States early manned spacecraft project. Since the sixties of last century, the former Soviet Union, space agencies of the United States compete to expand the manned spacecraft project. Such as female astronaut into space, the Soviet Union in 1963 years ago humans first female astronaut into space two years later, the first female U.S. astronaut into space in 1983.
NASA to catch up in order to achieve the Skylab program, has approved astronauts into space, to drive rapid development of the U.S. manned space technology. In 1969, the United States for the first time astronauts to the moon, the human dream has long been landed on the moon ideal. Accordingly view, on the space planning and technology, today compared with the United States, there is a considerable gap.

U.S. military advantage based satellite
talked about China’s current progress in space planning and technical, may be more than the continued growth of the gross domestic product (GDP) U.S. shocked by this layer concerns mainly derived from the use of space planning and technology in the military. Is well known, especially in space planning and technology, civil and military are only separated by a layer of paper, civilian technology pierce is a military technology.
since the United States strategic concept of the “high frontier”, the Americans sustained, space planning as the main event, naturally focused on the development and use of a variety of applications satellite program. Reconnaissance, communications and positioning satellite applications, the U.S. come out on top, and thus in the military to master and control space, master, control of the United States strong in a high-tech local wars, world rare their horses. Indeed, to master and control the “high frontier”, which is in the military to master and control the Earth.
the U.S. relative to other countries, the army, As former U.S. Defense Secretary William Perry said, the gap between large modern army, like the one holding a rifle and one holding a bow and arrow and long army of ancient spear. Depends mainly on the communications satellite to study their heritage, to cover the U.S. military’s advantage is built on the basis of its satellite system, the U.S. real-time command and control, precision strikes mainly rely on Global Positioning System, the battlefield of the U.S. military is one-way transparency depends mainly on a variety of reconnaissance satellites.
, even if the U.S. satellite system to lose some functionality, the U.S. military communications, positioning and reconnaissance and other means shall suffer heavy losses, the U.S. military to play a high-tech local wars, compared with other large army, it returned to the United States and the former Soviet Union tense confrontation, the situation of the strength of a draw in the 1960s and 1970s.
Accordingly, the United States may not be the rapid development of China’s space technology lightly.
