What are the applications of space science and technology in industry and life?

In fact, some important achievements in space science and technology have been popularized and applied in all sectors of the national economy, which has effectively promoted economic development. For example, dozens of new materials are used in machinery manufacturing; Some test stands have been used to improve the life of civil machinery; The structural test method and device of the space shuttle have been extended to the development of various aircraft, new cars and agricultural machinery. The automatic landing system of the space shuttle is also used for all-weather landing control of civil aviation and cargo aircraft; Computer-aided design and computer-aided manufacturing technologies developed for the development of space shuttles and other spacecraft have been applied to other industries. The popularization and application of aerospace technology in the field of civil industrial technology has greatly promoted the technological upgrading of various sectors of the national economy.

Space technology has also brought good news to medical and health undertakings, and it is not uncommon to use the achievements of space technology to check and treat diseases. For example, space technology can be used to treat heart disease. Now we can transplant microcircuits and nickel-cadmium batteries from satellites to make rechargeable implantable pacemakers to help patients' hearts work. This kind of pacemaker is small in size and light in weight, and can be charged from outside the patient's body, thus reducing the pain caused by replacing the pacemaker. Another example is the blood pressure detector used to monitor the physical condition of manned spacecraft astronauts. At present, it is placed in various public places in the United States for patients with hypertension to check their blood pressure, which is very convenient to use. The instrument can analyze the blood condition of human body according to the sound of blood flow, measure systolic blood pressure and diastolic blood pressure, and automatically record the blood pressure data measured every time for doctors' reference. Using infrared photography interpretation technology in aerospace technology, we can determine the burn degree of burn patients and the range of necrotic tissue in deep subcutaneous tissue, thus providing reliable basis for early escharectomy and skin grafting, and avoiding the self-healing tissue from being cut by mistake. Using the sensitive radiometer used on the spacecraft, the temperature change of 0. 1 degree Celsius can be measured. Because the temperature of cancer tissue is higher than that of normal tissue, it can be used to detect where there is cancer. It can also measure the temperature difference deeper in the human body. The achievements of space technology can also be used to manufacture new medical and health care instruments. For example, the automatic microbial detector used on spacecraft can measure the microbial content in liquid within 15 minutes on the ground; Using space technology, a folding walker can be made for patients with lower limb paralysis who can go up and down stairs. The automatic optical microscope developed in space exploration can enhance the unclear images taken in space into high-resolution display images. Using automatic optical microscope in medicine can improve the effect of X-ray images and make other pathological images clearer.

Tele-electronic medical system developed by ground monitoring and control center to monitor the physical condition of astronauts on spacecraft can also be used in medical and health undertakings, which is telemedicine. It can connect medical staff in remote areas and senior doctors in big city hospitals to solve the treatment problems of difficult and sudden diseases in remote areas. For example, in March of 1989, the United States provided a compatible satellite earth station, located in Armenia, and began medical consultation between countries. Medical facilities in the United States are connected to hospitals and rehabilitation centers in Armenia through satellites of commercial satellite companies and international satellite companies. Two days a week, provide one-way TV and two-way communication for several hours every day, and provide medical consultation and help.
