Shenzhou VI spacecraft is still the three-compartment structure of the propulsion module, the return module, the orbital module, the shape and structure of the entire ship and the original same, the weight of the basic to remain at about 8 tons. After entering the orbit, the spacecraft will first run on an elliptical orbit with a perigee of 200 kilometers and an apogee of 350 kilometers for 5 laps, and then change to a circular orbit 343 kilometers away from the ground, and it will take 90 minutes to fly around the Earth, and the flight track will be projected to the ground as a sinusoidal curve that is constantly moving to the east. The orbital characteristics are the same as those of Shenzhou V.
Since there is no rendezvous and docking mission on this flight, Shenzhou VI has canceled the additional segment used for this function. In addition, more than 40 pieces of equipment and six pieces of software have been newly added to the spacecraft, bringing it to more than 600 pieces of equipment, 82 pieces of software, and more than 100,000 components.
Shenzhou VI's improvements can be roughly summarized in four areas: [blocked ads]
I. Improvements centered around a two-person, multi-day mission. First, an adequate or even spare amount of astronaut consumables, including food, water, sleeping bags, etc., were prepared. Food cabinets were placed in the orbital module, which was previously in a vacant state. Astronaut water was prepared both in tanks and in individual soft packs, based on one and a half warmers per person per day. Second, the environmental control of the cockpit was improved. One person exhales nearly a liter of water a day. Shenzhou VI has improved its ability to condense water vapor, enlarged the condensate tank, and plastered all exposed piping with water-absorbent materials to ensure that the spacecraft's humidity is controlled at less than 80 percent. Oxygen, temperature and humidity in the cabin can be automatically sensed and adjusted.
Second, the orbital module has been improved in terms of function and use. A lot of necessities for astronauts' life have been placed, such as food heating devices and tableware. There is a sleeping bag hanging in the orbital module for two astronauts to take turns resting. Under weightlessness, a person can actually float in the air and sleep, but considering the habits that people have developed on the ground, the sleeping bag is used to artificially create a feeling of "bed", otherwise the astronauts may have the illusion of falling into an abyss when they sleep. The orbital module also has a special cleaning supplies cabinet, astronauts can use the wipes and other items for cleaning. The urine and feces collection device was also used for the first time this time.
Third, improvements to enhance astronaut safety. The astronauts' chairs in the return capsule are designed with a landing cushion function, which is designed to ensure the safety of the astronauts in case of a failure of the thrust reverser rocket. Shenzhou V spacecraft, only Yang Liwei riding in the chair with landing buffer function, and there is a small defect, is to return to the chair before lifting the astronauts difficult to see the situation outside the porthole. Shenzhou VI has redesigned the buffer and combined it with the whole ship for repeated tests, and the three tests thrown down from high towers and airplanes have been successful each time. The hatch between the return module and the orbital module will threaten the safety of the astronauts if it is not closed tightly when returning. Three Russian astronauts have died as a result. Shenzhou VI researchers successfully developed a rapid automatic detection device for hatch closure, and spent months developing a special rag that does not produce fibers, static electricity, or odors, and is specifically designed to clean the hatch.
Four, continuous improvement. China's manned spaceflight project was officially launched in 1992, and 13 years have passed since then, some of the components and raw materials initially used on the spacecraft are no longer in production, and individual technologies have become slightly outdated. Shenzhou VI has made some daily continuous improvements. For example, the "black box" on Shenzhou I to V was developed in 1994, with a storage capacity of only 10 megabytes. Now the black box is not only 100 times larger than the original storage capacity, and data writing and reading speed has increased by more than 10 times, but the volume is less than half of the original.
Shenzhou VI spacecraft composition
Orbital module: "multi-purpose hall"
Shenzhou spacecraft orbital module is a cylinder, the total length of 2.8 meters, the maximum diameter of 2.25 meters, one end and the return module, the other end and the space docking station. Connected to the other end of the space docking agency connected. The reason why the orbital module of "Shen6" is called "multi-functional hall" is because the two astronauts have to enter the return module in addition to the lift-off and return, and other times are in the orbital module. The orbital module set work, eat, sleep, wash and convenience and many other functions in one.
Escape Tower: Keeping the Spacecraft Safe
Escape Lifeguard Tower: Located at the very front of the spacecraft, it is 8 meters high. It itself is actually a small launch vehicle composed of a series of rocket engines. In the carrier spacecraft rocket takeoff 900 seconds before to 160 seconds after takeoff period? Rocket running distance of 0 to 100 kilometers, once an emergency occurs, this life-saving tower will start in an emergency, pulling the "Shenzhou VI" spacecraft return capsule and orbital module and the rocket separation, rapid escape from danger, and the use of parachutes to land in a safe area.
Retaining orbit module: astronauts' "home"
Orbital module: also called the work module. Its shape is a cylinder with tapered corners at both ends, and it is the astronauts' "space bedroom" and "work room". It also has two functions of astronauts' living module and orbital experiment module, so it is also called orbital module. Inside the orbital module, there are many kinds of experimental equipment and experimental instruments, which can be used for earth observation, and both sides of the module are equipped with retractable large-scale solar cell wings, solar sensitizers and various antennas, as well as various docking structures, which are used for converting solar energy into the energy source of the spacecraft, and communicating with the ground, and so on. As the astronauts' "space bedroom", the orbital module's environment is very comfortable, and the temperature inside the module is generally between 17 and 25 degrees Celsius.
Return capsule: astronauts' "cab"
Return capsule: also known as cockpit, it is the astronauts' "cab". It is the cabin section where astronauts ride when traveling to and from space, and it is a closed structure with a hatch at the front end. "After Shenzhou VI completes its flight around the earth, the two astronauts will return to the earth in the return capsule.
Propulsion module: also called instrument module. It is usually equipped with a propulsion system, power supply, orbital braking, and oxygen and water for the astronauts. Both sides of the propulsion module are also equipped with the main solar cell sail wings with an area of more than 20 square meters.
Why choose the fall launch?
Morning News comprehensive Xinhua News Agency, careful people will note that two years ago at this time, China's first manned spacecraft Shenzhou V launched successfully. The launch of Shenzhou VI this year, again in the fall, is it a coincidence? No. That's because the meteorological conditions in the fall are the most suitable for China to launch a manned spacecraft.
The selection of the launch season for a spacecraft takes into account a variety of factors that may affect the launch, of which meteorological conditions are the most direct and critical determinant.
After the spacecraft takes to the skies, it is up to the spaceflight measurement and control network to implement measurement and control management for the spacecraft. If the Shenzhou spacecraft is compared to the "kite" flying in space, then the spaceflight measurement and control network is the important "kite line". China's spaceflight measurement and control network consists of a number of ground measurement and control stations and four spaceflight measurement ships, namely, the Pacific Ocean Surveyor, the Pacific Ocean Surveyor, the Pacific Ocean Surveyor and the Pacific Ocean Surveyor. These four survey ships are the "Yuanwang" No. 1 and "Yuanwang" No. 2 in the Pacific Ocean, the "Yuanwang" No. 4 in the Indian Ocean, and the "Yuanwang" No. 4 in the Atlantic Ocean. "Far Sight No. 3 in the Atlantic Ocean. Three of the ships are in the southern hemisphere, where latitude is relatively high.
The seasons in the southern hemisphere are exactly the opposite of ours. China's spring and summer seasons in the southern hemisphere is the fall and winter seasons, sea conditions are very poor, even normal navigation is difficult to ensure safety, let alone at sea to carry out measurement and control tasks, so it is not suitable for launching spacecraft. China's fall and winter seasons in the southern hemisphere is the spring and summer seasons, sea conditions are better, easy to navigate and perform measurement tasks. Therefore, China's Shenzhou 1 to 5 spacecraft launch timing are selected in the southern hemisphere and the opposite of the fall and winter seasons.
In addition, compared with winter in autumn, although Shenzhou IV, launched on December 30, 2002, had broken the historical record of low-temperature launches in China, in manned space flights, people-oriented and fully guaranteeing the safety of astronauts have become the most important features of the launches, and thus the meteorological conditions of the launching section are also very important. Obviously, fall is more suitable than winter. Therefore, the Shen5 two years ago and this year's Shen6 manned spacecraft both chose to launch in the fall.
According to Gong Jiancun, a researcher at the Space Environment Prediction Center of the Chinese Academy of Sciences, "This year is exactly the position near the bottom of the cycle, and it is expected that the solar activity will be stable during the flight of Shenzhou VI, which is suitable for human space activities."
Gong Jiancun said, people have grasped the sun's activity cycle is 11 years, 2000 is the peak of this cycle, 2006 reached the bottom. Therefore, this year, the frequency of solar anomalous activity is low, the general trend is favorable to human space activities. Shenzhou VI will fly in "good weather"
From Shenzhou V to realize China's zero breakthrough in manned spaceflight, to Shenzhou VI's more than two days of space flight, China's astronauts special milk Mengniu milk, accompanied the astronauts from the sweaty training ground to the vastness of space, witnessed China's manned space industry hard and brilliant. It has witnessed the hardship and splendor of China's manned spaceflight career. What are the special requirements for the selection of food for astronauts, and how did Mengniu milk become the "Special Milk for Chinese Astronauts"? Along with the successful return of Shenzhou VI, the mysterious veil shrouding the astronauts' recipes has been gently lifted by nutrition experts.
In China, an air force pilot to be selected from 1,000 military personnel, and 100 air force pilots, only one person has the opportunity to become a fighter pilot, astronauts from these fighter pilots in a thousand, after a comprehensive examination of all aspects of the comparison of the final selection out. In order to ensure that these shoulders of the motherland's heavy responsibility of the "national treasure" to maintain good physical and mental quality, as early as Shenzhou V before the first manned space mission, a nutritional team composed of experts from various parties began the harsh astronauts special food selection work. In order to ensure the safety, greenness and nutrition of spaceflight food, the regulations of the Institute of Aerospace Medical Engineering on food for astronauts are as long as eight pages! The "whole nutritious food" milk inspection and selection of the first to bear the brunt.
Milk source is the first key to determine the quality of milk, and thus also become the primary factor in the assessment of experts. Considering that the prairie of Inner Mongolia as the core of China's western prairie is located in the internationally recognized medium-temperate monsoon climate of high-quality dairy cattle feeding zone, is the whole of China's unparalleled and the world's leading significance of high-quality prairie, the main source of milk bases are all in the zone of Mengniu Dairy into the vision of the experts. In Mengniu's production base, they saw the world's leading "model factory", where every drop of raw milk goes through a fully automated process to become a rich and qualified milk product, and the whole process is carried out in a closed and sterile state. From the market to the factory and from the factory to the farm, Mengniu's milk performance has convinced every expert.
The national aerospace department, after rigorous testing, concluded that all indicators of Mengniu milk have met or exceeded domestic and international standards. With its natural, high quality, rich nutrition and good taste, Mengniu milk eventually became the only milk designated by space nutrition experts as "special milk for Chinese astronauts". Since then, "three glasses of milk a day" has become a "white music" in the training, work and life of astronauts.
Every morning, while enjoying other carefully prepared food, the astronauts have to drink a glass of Mengniu milk to effectively guarantee calories and nutrition throughout the day. And after lunch, the training base's nutritionist will promptly serve each astronaut a cup of Mengniu yogurt. It turns out that the organic acids contained in yogurt, such as lactic acid and acetic acid, not only give yogurt a refreshing sour flavor, but also help milk form a fine curd, thus lowering the intestinal pH, promoting gastrointestinal peristalsis and secretion of digestive juices, and inhibiting the reproduction of harmful microorganisms, so that the astronauts are refreshed for an afternoon. "Mengniu has changed the probiotics in its yogurt products from two to four, so that not only is the nutritional value significantly higher than that of similar products, but its role in aiding digestion and inhibiting harmful bacteria has been strengthened even further, making it very popular with the astronauts." The nutritionist at the base commented this way.
After finishing a day of intense training, the astronauts will also drink a glass of milk at dinner. Nutrition experts pointed out that, on the one hand, the tranquilizing effect of the milk consumed at dinner promotes deep sleep among the astronauts, and on the other hand, it is easier for the human body to absorb the proteins in milk when it is in a sleeping state.
"Three glasses of milk a day, 500-800 milliliters a day. This scientific recipe not only ensures the nutritional supply, but also does not cause fat accumulation, not only applies to astronauts, with samples also applies to ordinary people"! Nutrition experts believe that the astronauts meals in the scientific collocation of milk, it is worthwhile to vigorously promote in the whole society.
Becoming the "Chinese astronauts special milk", for Mengniu, is not only a high honor, but also a kind of expectation and responsibility. At the same time that China's aerospace industry is "inspiring China's heart" with one brilliant achievement after another, every Mengniu person is also committed to the great mission of "strengthening Chinese people". 2003, when Shenzhou V rose up to the ground, realizing the zero breakthrough in China's manned spaceflight, Mengniu's milk also quickly became the most important part of the Chinese spaceflight industry. In 2003, when the Shenzhou V was launched, realizing the zero breakthrough in China's manned aerospace industry, Mengniu's milk quickly became the leader in China's liquid milk market, and in 2004, Mengniu's milk became the special milk for athletes' training of the Training Bureau of the General Administration of Sport of the People's Republic of China, dedicating itself to China's athletes' development in world games. Afterwards, Mengniu took the lead in building China's largest "Australia-Asia International Farm", the first to introduce robotic milking facilities in China, planting the world's twelve high-quality pasture, breeding global high-quality cows, and opening up the road of upgrading China's dairy industry milk sources. 2005, when Shenzhou VI revolved around this beautiful planet of ours in a perfect posture, Mengniu was the first to be awarded the title of the first Chinese milk producer in the world, which is the largest milk producer in China. In 2005, when Shenzhou VI circled around our beautiful planet with a perfect attitude, Mengniu had already surpassed many multinational dairy giants with a daily sales of 7,000 tons of liquid milk, becoming the global leader in the field of liquid milk. As the first "China's aerospace partner", Mengniu will not only "applaud for China", but will also use its white and mellow milk to cheer for the health of every astronaut and every Chinese person, and to pursue the "dream of a strong and healthy China" tirelessly. "The company's goal is to provide the best possible service to its customers.

Following the success of China's first manned flight of Shenzhou V, the Shenzhou VI spaceflight project has already begun. "Six" space project has been in the tension. In order to put the country's "dream of flying" to another new height, "Shenzhou" six pre-launch preparations have been fully underway. As the "God of Help" of the spacecraft, the "Long March 2F" carrier rocket will take up the important task of sending the "Shenzhou" No. 6 into the sky and into orbit. "Although the power carriers of the Shenzhou V and Shenzhou VI spacecraft are the same type of rockets, the rocket system for launching Shenzhou VI is "another article ". Yesterday, Liu Zhusheng, chief designer of the rocket system, accepted an exclusive interview with this reporter to explain the "Shenzhou" six rocket focus.
Focus 1 rocket delivery time at the end of the equipment configuration
To assume the "Shenzhou" six launch of the rocket system chief designer Liu Zhusheng to the reporter revealed the launch of the "Shenzhou" six rocket system to prepare for the timetable. According to Liu Zhusheng's introduction, the end of 2004, the rocket system equipment are "on schedule", each set of instruments are required to configure a complete set of rocket system for the subsequent early next year to prepare for the comprehensive experiment. Liu Zhusheng said, comprehensive experimental stage, each component of the rocket into their respective laboratories for testing, the purpose is to ensure that the rocket as a whole up to standard, after passing the test, the system will be "division", to match the experiment.
Focus 2: Rocket emergency response capabilities are being calculated at the limit
The launch vehicle's "limit analysis" is dedicated to a series of major changes within the Shenzhou VI spacecraft. Liu Zhusheng said: "First of all, because the 'Shenzhou' six will realize multi-people multi-day flights, the increase in the number of people and the number of days to bring the increase in the quality of food, survival equipment and other mass, which requires that the rocket's capacity must be increased, such as the original 'Shenzhou' five of seven or eight. For example, the original 'Shenzhou V's' seven or eight tons of mass may have to become more than eight tons. Secondly, if there is more than one astronaut, problems during the flight will directly affect the escape capability, challenging the emergency response capability of the rocket when it encounters unexpected situations." Liu Zhusheng said, for the above two points, is currently coordinating and cooperating with the spacecraft system aspects of the relevant rocket limit calculations. It is understood that, at present, such "limit analysis" has been done several rounds.
Focus 3 Rocket power characteristics will be adjusted with the load change
Rocket with the spacecraft to form a "big spring" system, Liu Zhusheng said: "From the dynamics of the analysis, the spacecraft and the rocket connected to the impact of interaction, due to the 'Shenzhou', the spacecraft and the rocket connected to the system, the spacecraft and the rocket will interact with each other. 'Shenzhou' six orbital module payload will be from the original 'Shenzhou' five on a number of equipment into one or two devices, the changes in the airship's mass of the block is bound to affect the entire rocket's dynamics, the current work involves the rocket and airship dynamics features corresponding problems."
