What you need is a house. To build a house, you need cement. If you want to drive a car or motorcycle, you need to burn gasoline.
Question 2: What are the things used in life, such as space technology, electric energy-saving system, smoke detector, food desiccant, sunglasses, electric drill radio equipment, diapers, solar energy, microwave oven, memory foam,
Question 3: The application of space technology in life. To give a few examples, diapers, dehydrated vegetables in instant noodles, space breeding, solar panels, satellite navigation and so on. They are all contributions to space technology, which can be said to cover all aspects of food, clothing, housing and transportation.
In the development of space technology, there will inevitably be various problems, which will form a large number of demands and further promote the development of technology. Like the example mentioned above, others are far away from people. For example, the demand for new materials in aerospace has promoted the development of the chemical industry. Organic fluorine, the gasket material originally used for aerospace vacuum isolation, has now become the fist product of China Chemical Industry.
Are there any other examples, Tom? Cruise wore a invisible braces made of translucent polycrystalline alumina from NASA. Yao Ming once used the "anti-gravity treadmill" developed for the space station for recovery training; Sunglasses, originally invented to prevent astronauts' eyes from being burned by strong light, have long been a necessity for "fashion hipsters"; In recent years, the high-definition camera technology of iPhone, which is highly sought after by young people, is inseparable from the CMOS photosensitive elements used in space telescopes.
Question 4: The application of space technology in life. How to fill in the rest? Space technology is used in life, mobile phone, mobile communication, navigation, positioning, space breeding,
Question 5: What benefits can space technology bring us? Satellites can also provide farmers with crop yield estimation and pest prediction, and provide fishermen with fish location information. "China's multi-modal microwave remote sensor has achieved all-weather and all-day observation ability, and it is self-evident that seafood can be seen, where there are fish schools and how big the fish schools are."
Medicine
Using space technology to develop man-made organizations
NASA has developed a "bioreactor" for research. These reactors are used to make human tissues such as ligaments. They neutralize gravity, so cells can grow as if they were in the body. The miniature heart pump is developed by using the fuel pump technology on the space shuttle.
Space sickness drugs can also treat seasickness.
The first case of space disease was accompanied by manned space flight, which was a directional obstacle caused by weightlessness. Cosmic medicine has developed a variety of drugs and equipment to solve the above and other diseases caused by long-term weightlessness. Some of these methods can also be used to treat common diseases, such as seasickness.
Intelligent materials improve the technology of making artificial limbs.
NASA's research on the next generation space shuttle technology will have a wide impact. At present, we are studying "smart" materials that can still remember the original shape after being changed. This material may help to improve the technology of making artificial limbs.
Derived a device for measuring physical condition.
Non-invasive sensors used to measure pulse and other physical conditions come directly from similar equipment used to monitor astronauts.
New drug research and development
"Humans have made a lot of scientific achievements in space activities in the past half century, some of which have been used to improve human life, and some will be reflected in people's lives in the near future."
From the life-threatening "artificial heart" and kidney dialysis technology to a pair of sports shoes on the feet, all of them are "masterpieces" of aerospace technology.
[Space Vegetables]
Space has a unique high vacuum, strong radiation, microgravity and other environments that are difficult to simulate on earth, providing an ideal experimental site for scientific research. Using special space environment to induce plant character variation and cultivate new varieties with excellent characters is space breeding.
Since 1987, more than 300 kinds of crop seeds have been developed in China, and more than 50 strains have been planted and popularized in a large area.
According to incomplete statistics, 43 strains have been planted and popularized in large areas in China, and there are space breeding bases in Beijing, Shanghai, Heilongjiang, Jiangsu, Gansu and other places. "Hangjiao No.3 and No.4", "Space Cucumber" and "Hangqie 1 No.3" ... The nutritional content of these delicious space vegetables has generally increased by 30% ~ 46%, and they have been put on the table of ordinary people's homes.
Of the more than 1000 new materials developed in China in recent years, 80% were developed under the traction of space technology. Nearly 2,000 achievements in space technology have been transplanted to various sectors of the national economy.
Among the millions of protein in human body, less than 1% is known. "In the microgravity environment in space, protein can grow very large crystals, which can be used for structural analysis. If it is applied to pharmaceuticals, every successful protein structural analysis will produce a new product. "
It is reported that the R&D cost of developing a new drug in the United States is generally between 500 million and 654.38 billion US dollars, with an average time of about 5 years. Undoubtedly, studying protein in space environment will greatly improve efficiency and quality, and the research results may be used to change human health, solve food and medicine problems and greatly improve people's quality of life. Hu Wenrui estimates that it may take decades to turn these into reality. However, once the results are applied, the changes of human life will be unpredictable. "
Space food facilitates daily life.
Many freeze-dried foods in supermarkets are foods eaten by astronauts.
[Life] Staring at the birth of a mattress that can release stress
The "memory foam" mattress made of polyurethane was invented by NASA. Mattress made of this kind of foam can release pressure and give good support to all parts of the body.
Invent smarter robots
Compared with the speed of light, the communication time between humans and robots exploring the whole solar system is too long, and it is difficult for ground control to make "real-time decisions". Therefore, engineers on the spacecraft invented more and more intelligent artificial information systems, allowing robots to make decisions automatically without human control.
Show humans something farther away.

Question 6: Examples of the application of space technology in people's lives When it comes to space technology, everyone's first reaction must be unfathomable, just like the feeling that space gives people, out of reach. In fact, many aerospace technologies have been applied in our daily life! Come with me and see how those strange space technologies are applied to our lives!
Anti-scratch glasses
As we all know, there are a lot of dust and small particles floating in the space environment where we live. To this end, NASA invented a special coating to protect space equipment, especially astronauts' helmets. Later, NASA authorized an American sunglasses manufacturer to make sunglasses with this special plastic coating. The scratch resistance of sunglasses is more than ten times stronger than that of ordinary glasses. Look at the difference between sunglasses and ordinary glasses!
satellite phone
Do you know why we can call our friends across the ocean? Thanks to the satellite. Before humans could go into space, NASA built satellites to let people observe the situation in outer space. Later, using this satellite technology, satellite phones came into being. Now there are about 200 communication satellites orbiting the earth every day, providing us with the service of transnational satellite calls!
Ear thermometer
Do you remember? When influenza A (H 1NI) is prevalent, students should take their temperature every day when they enter the campus. Have any careful children observed the thermometer for measuring body temperature? The traditional mercury thermometer is not only time-consuming, but also difficult to identify, which always makes people feel inconvenient. Since the ear thermometer, this problem has been solved! The ear thermometer was jointly developed by NASA and Diatek in 199 1 year. It uses infrared rays to measure temperature, which can accurately measure human body temperature within two seconds. With it, we can measure our temperature quickly and well!
Elastic insole
Do you know what's in the astronaut's insole? It turns out that the moon boots worn by astronauts in the American Apollo program are equipped with special insoles, which not only provide flexibility for astronauts to walk on the moon, but also provide ventilation. Since the success of landing on the moon, many sports shoes companies have adopted this technology, placing elastic cushions on the soles, which has been widely welcomed. Now these insoles are widely used in our sports shoes. Now, do you think shoes are getting lighter and lighter?
water filter
How is the pure water we drink every day purified? Thanks to the Americans. They invented water filtration technology in the early 1950s. In order to keep clean water for a long time under more extreme conditions, NASA has further improved the filtration technology of clean water. The water filter is built with large activated carbon, which can eliminate pathogens and kill bacteria in water after special activity treatment. At the same time, charcoal can also prevent the further growth of bacteria. Many water filter manufacturers use this technology to provide pure drinking water to countless people around the world every day. When you are free, you can carefully observe the water dispenser at home to see if there is activated carbon in it.
Hope to adopt!

Summary: From 1999 to 2005, six years, six spaceships and six leaps, the speed and efficiency of China's manned space flight amazed the world and made hundreds of millions of people in China feel encouraged and proud. In six years, six spaceships and six breakthroughs, China astronauts used their wisdom and efforts to make up for the lack of material and technical foundation and created a rapid leap in manned space flight in China.
Like other space powers in the world, China's space industry began with the development of missiles.
In the mid-1950s, Chairman * * * and the CPC Central Committee issued a call to "March into science", and Premier Zhou Enlai organized and formulated a long-term plan for the development of science and technology, including rocket technology.
1In February, 956, Dr. Qian Xuesen, who had just returned from overseas, put forward suggestions on developing missile technology. Under his auspices, more than 30 experts and 100 college graduates formed a scientific research team, which was at the peak of simplicity and arduousness.
1956 10. On 8 October, under the direct leadership of Marshal Nie, the Fifth Research Institute of the Ministry of National Defense was established. China's scientific and technical personnel and workers began to learn their own design skills through imitation with the aid of the Soviet Union.
1960165438+1On October 5th, the first short-range surface-to-surface missile copied by China rose from the eastern horizon.
1962 March 2 1 day, the first medium-and short-range missile designed and developed by China failed to launch for the first time. However, the first major setback in the development of space technology did not discourage scientific and technological personnel.
1On June 29th, 964, the medium and short-range missile independently developed by China was successfully launched. It marks a good beginning for China's strategic missile development.
Since then, China's fledgling space industry has been reported frequently: 1966, the missile nuclear weapon launch test was successful; 1970 medium-range and long-range missiles have successively completed flight tests; 197 1 The flight test of the long-range missile was basically successful. All these have laid a solid foundation for the development of China's ground-to-ground strategic missile technology.
Since 1980s, China's long-range strategic missile test and underwater submarine's launching of solid strategic missiles have been successful, which shows that China has mastered effective nuclear counterattack capability and improved the level of national defense modernization. At the same time, great progress has been made in the development of various tactical missiles.
"We also want to build satellites."
1958 in may 17, chairman * * * put forward at the second meeting of the eighth national congress of * * *: "we also want to build satellites." From 65438 to 0965, based on the development of surface-to-surface missiles in China, the first artificial satellite was developed.
