Question 2: What are the things in life that use aerospace technology Electric energy-saving systems, smoke detector, food desiccant, sunglasses, drilling radios, diapers, solar energy, and the use of aerospace technology in the life of a person. Microwave ovens, memory foam,
Question 3: The application of space technology in life To give a few examples, diapers, instant noodles in dehydrated vegetables, aerospace breeding, solar panels, satellite navigation and so on have the contribution of aerospace technology, can be said to cover all aspects of food, clothing, housing and transportation.
In the development of space technology, it is inevitable that a variety of problems will arise, and these problems also form a lot of demand, which in turn drives the development of technology. The ones that are close to people are mentioned above, and there are some that are farther away from people, for example, the demand for new materials in aerospace has pushed the development of the chemical industry, and the sealing gasket material organic fluorine used in aerospace in order to isolate the vacuum is now the fist product of the chemical industry in China.
There are some other examples, Tom Cruise wore a gasket used by NASA. Cruise wore invisible braces made of polycrystalline aluminum oxide, a translucent material used by NASA; Yao Ming has recovered with the help of an anti-gravity treadmill developed for the space station; sunglasses, initially invented to prevent astronauts' eyes from being burned by bright light, have long since become a must-have for the "fashionable and trendy"; and in recent years, sunglasses have become a must-have for the "fashionable and trendy". "The iPhone, which has been highly sought after by young people in recent years, has a high-definition camera technology that can't be separated from the CMOS sensor used in space telescopes.

Artificial Tissues Developed with Space Technology
NASA developed "bioreactors" for research, which are used to create human tissues such as ligaments. They neutralize gravity so cells can grow as they would in the body. The miniature heart pump was developed using fuel pump technology from the space shuttle.
Space Disease Drugs Also Cure Seasickness
The first case of space sickness followed manned space flight, and it was disorientation caused by weightlessness. Cosmic medicine has developed a variety of drugs and devices to address these and other ailments caused by prolonged weightlessness. Some of these methods can also be used to treat common ailments such as seasickness.
Smart Materials Improve Technology for Prosthetics
NASA's research on the next generation of space shuttle technology will have broad implications. Research is underway on "smart" materials that have memory of their original shape even after they have been altered. Such materials may help improve the technology for making prostheses.
Derivation of Devices for Measuring Physical Conditions
Non-invasive sensors for measuring pulse and other physical conditions are directly derived from similar devices used to monitor astronauts.
New drug development
"Nearly half a century of human activity in space has yielded a large number of scientific results, some of which have already been used to improve human life, and some of which will be embodied in people's lives in the near future."
From the life-threatening "artificial heart", kidney dialysis technology, to the feet of a pair of travel shoes, are space technology "masterpiece".
[Space vegetables]
Space has a difficult to simulate on Earth, unique high vacuum, strong radiation, microgravity and other environments, for scientific research provides an ideal experimental place. Utilizing the special environment of space to induce variation in plant traits and cultivate new varieties with excellent traits is space breeding.
Since 1987, China has carried out more than 300 kinds of crop seed satellite piggyback test, completed more than 50 strains of large-area planting promotion.
Incomplete statistics show that, at present, China has 43 strains in large-scale planting and promotion, Beijing, Shanghai, Heilongjiang, Jiangsu and Gansu and other places have space breeding base. "Aero-pepper three, four" "space gourd melon" "Aero-eggplant one, three" ...... these delicious space Vegetables, nutritional content generally increased by 30% to 46%, has been placed on the table of ordinary people.
China in recent years, more than 1,000 kinds of new materials, 80% is in the space technology under the traction of the development of the completion; nearly 2,000 space technology results have been transplanted to various sectors of the national economy.
Of the millions of proteins in the human body, less than one percent have been understood by humans. "In the microgravity environment of space, proteins can grow very large crystals that can be used for structural analysis. If applied to pharmaceuticals, every successful analysis of the structure of a protein will produce a new product."
It is reported that the United States for the development of a new drug research and development costs are generally in the range of 500 million to 1 billion U.S. dollars, an average of about five years. Studying proteins in a space environment will undoubtedly greatly improve efficiency and quality, and the results may be used to change human health, solve problems such as food and medicine, and greatly improve the quality of human existence. Hu estimates that turning these into reality "may take a few more decades. However, once the results are applied, the changes to human life will be hard to estimate."
Space food facilitates daily life
Much of the freeze-dried food in supermarkets is what astronauts eat.
[Life] Staring at the birth of a mattress that releases pressure
The "memory foam" mattress, made of polyurethane, was invented by NASA. A mattress made of this foam releases pressure and gives complete support to all parts of the body.
Inventing Smarter Robots
Human communication with robots exploring the entire solar system takes too long, relative to the speed of light, for ground control to make "snap decisions". So engineers on spaceships have invented ever-smarter artificial information systems so that robots can make decisions automatically, without human control.

Question 6: Examples of the use of space technology in people's lives When it comes to aerospace technology, the first reaction of people must be unfathomable, just like the feeling that space is out of reach. In fact, many of the technologies in the field of aerospace have been applied in our daily life! Just go with me to see how those unfamiliar space technology is applied to our lives!
Anti-scratch glasses
As we all know, we live in the space environment floating in a lot of dust and small particles, NASA invented a special coating to protect space equipment from its harm, especially the astronauts' helmets. Later, a sunglasses manufacturer in the United States was authorized by NASA's technology to make sunglasses with this special plastic coating. Sunglasses are more than ten times more resistant to scratches than ordinary eyeglasses. You guys understand the difference between sunglasses and ordinary glasses!
Satellite phones
Do you know why we can call our friends across the ocean? This is the credit of the satellite. Before mankind was able to enter space, NASA built satellites to allow people to observe conditions in outer space. Later, using this satellite technology, satellite phones were created. Now there are about 200 communication satellites orbiting around the Earth every day, providing us with cross-country satellite calls!
Ear Thermometer
Do you remember? When Influenza A H1NI was prevalent, students had to measure their body temperature every day they entered the campus. There is no careful children have observed the thermometer to measure body temperature? Traditional mercury thermometers are not only time-consuming to use, but also difficult to recognize, always making people feel inconvenient. Since the ear thermometer, this problem has been solved! Ear thermometer is NASA and the United States Diatek company developed in 1991, it uses infrared light in the measurement of temperature advantages, only two seconds can accurately measure the body temperature. With it, we can take body temperature fast and well!
Elastic insoles
Do you know what mysteries are in the insoles of astronauts? Originally, the U.S. Apollo program astronauts wore moon boots fitted with special insoles, which not only for astronauts walking on the moon to provide elasticity, but also ventilated and breathable. Since the success of the moon landing, many athletic shoe companies have adopted this technology, placed in the sole of the elastic cushion, has been widely welcomed. Now these insoles are widely used in our sports shoes. Now, doesn't it feel that the shoes nowadays are getting lighter and lighter when you walk?
Water filters
How is the pure water we drink every day purified? It's thanks to the Americans. They invented water filtration in the early 1950s. In order to keep clean water clean for a longer period of time under more extreme conditions, NASA has further improved the water filtration technology. Water filters have large pieces of activated charcoal built into them, and this charcoal is specially activated to eliminate pathogens and kill bacteria in the water. At the same time, the charcoal also prevents further bacterial growth. Numerous water filter manufacturers utilize this technology to provide pure drinking water to countless people around the globe every day. When you have time, you can carefully observe the water dispenser in your house to see if there is any activated charcoal in it?
Hope to adopt!
Question 7: What are the main achievements in the field of aerospace technology in China Find a lot, the most concise is this, choose to copy it
February 19, 1960, China's self-designed and manufactured experimental liquid-fueled sounding rockets launched successfully for the first time.
On April 24, 1970, the first artificial Earth satellite, Dongfanghong 1, was successfully launched from Jiuquan, making China the fifth country in the world to launch a satellite.
On November 26, 1975, China's first return satellite was successfully launched and returned three days later, making China the third country in the world to master satellite return technology
In October 1985, the Long March rocket began to go on the international market
On November 20, 1999, China's first unmanned test spacecraft, the Shenzhou, was launched. "China's first unmanned test spacecraft, Shenzhou 1, took off from Jiuquan and successfully landed 21 hours later at the recovery site in central Inner Mongolia.
At 01:00 on January 10, 2001, China's self-developed Shenzhou II unmanned spacecraft was launched from the Jiuquan Satellite Launch Center.
On March 25, 2002, Shenzhou III was successfully launched into space from the Jiuquan Satellite Launch Center, and on April 1, Shenzhou III successfully landed in the central region of Inner Mongolia.
Between December 30, 2002, and January 5, 2003, Shenzhou III was launched into space. From December 30, 2002 to January 5, 2003, the unmanned spacecraft Shenzhou IV was successfully launched in the freezing cold of -20 degrees Celsius and returned safely after seven days of flight.
On January 5, 2003, at about 7:00 pm, Shenzhou IV landed in the predetermined area in the middle of Inner Mongolia and was recovered smoothly. The Jiuquan Satellite Launch Center.
On October 15, 2003, China's first astronaut, Yang Liwei, took Shenzhou V into space, realizing the Chinese nation's millennial dream of flying into space.
On October 12, 2005, astronauts Fei Junlong and Nie Haisheng took the Shenzhou VI spacecraft to fly into space again, and returned to Earth safely after five days in space and a series of space experiments.
Summary: From 1999 to 2005, six years, six spaceships, six leaps, the speed and efficiency of China's manned spaceflight, the world marveled, hundreds of millions of Chinese people are encouraged, doubly proud. Six years, six spaceships, six breakthroughs, Chinese astronauts with their wisdom and efforts to make up for the lack of material and technological basis, creating a rapid leap in China's manned spaceflight.
Like other spacefaring nations in the world, China's spaceflight began with the development of missiles.
In the mid-1950s, President *** and the Party Central Committee issued a call for "marching towards science", and Premier Zhou Enlai organized the formulation of a visionary plan for the development of science and technology, including rocket technology.
In February 1956, Dr. Qian Xuesen, who had just returned from overseas, proposed the development of missile technology. Under his auspices, a research team consisting of more than 30 experts and 100 fresh university graduates peaked at the humble and grueling.
On October 8, 1956, under the direct leadership of Marshal Nie Rongzhen, the Fifth Research Institute of the Ministry of National Defense was established. China's scientific and technical personnel and workers began to utilize the Soviet Union's assistance to learn the skills of self-design through imitation.
On November 5, 1960, the first close-range surface-to-surface missile copied by China rose from the eastern horizon.
On March 21, 1962, the first launch of China's first self-designed and developed medium- and short-range missile failed. However, this first major setback in the development of aerospace technology did not discourage the scientists.
On June 29, 1964, China's independently developed medium- and short-range missiles were successfully launched. It marked a good start in the development of China's strategic missiles.
Since then, China's fledgling aerospace industry has been full of good news: in 1966, the launch test of missile nuclear weapons was successful; in 1970, the flight test of medium-range and medium- to long-range missiles was completed one after another; and the flight test of long-range missiles was basically successful in 1971. All this has laid a solid foundation for the development of China's strategic ground-to-ground missile technology.
Since the 80's, China's long-range strategic missiles and underwater submarine launched solid strategic missiles have been successfully tested, indicating that China has mastered the effective nuclear counterattack capability, and improved the level of modernization of national defense. At the same time, the development of various tactical missiles has also made significant progress.
"We also want to engage in artificial satellites"
On May 17, 1958, Chairman *** proposed at the second meeting of the *** Eighth National Congress, "We also want to engage in artificial satellites." In 1965, on the basis of the certain development of China's ground-to-ground missiles, the development of the first artificial satellite began.
