What are the practical applications of human space technology?

Space technology is closely related to our lives. According to a list from the National Space Agency, there are more than 700 applications in people's daily lives. Space science and technology in modern medicine is remarkable: laser angiography, a new generation of pacemakers, infrared thermometers, heat-sensing video (without surgery can determine the lesions in the human body), blood analyzers and so on. In addition, fire extinguishing systems, assessment of the damage caused by ultraviolet rays to human beings, lasers, satellite photographs, weather monitoring systems, all corrosion-resistant coatings and materials, the application of solar energy, wireless devices, water filtration devices, virtual display systems, portable computers, and so on, are also the application of aerospace science and technology in people's lives. Nowadays, all major hospitals in the world have intensive care wards, which is one of the most important applications of aerospace science and technology in human life. Various equipments in the intensive care wards were used in the 1960s to monitor the physical condition of astronauts traveling in space. Going to be limited to transporting machines into space orbit or sending probing radio waves into the distant unknown of space. Many branches of science are closely related to space. The discovery or creation of new materials, the study of the human body's physiological response to microgravity, intense radiation or high acceleration are just a few examples of space-related research. Although the initial goal of these new technologies was not to be applied on Earth, many of these technological advances have ended up as means to benefit humanity. The study of the consequences of human exposure to high radiation conditions and the search for ways to avoid the harmful effects of radiation on the blood of astronauts have led to the discovery of treatments for blood diseases such as leukemia and anemia. New advances in the field of bio-nanotechnology are also being applied in medicine. It was envisioned that nanoparticles could be placed in human cells to act as an extremely tiny sensor. As long as this nano-sensor found the existence of some kind of problem, such as viral invasion, it will inform people by means of luminescence and other means of the body out of the problem of aerospace science and technology into the implementation of industrial productivity, into the technology that can be commercialized, civil use, should be the goal of mankind *** with the efforts.
