Ouyang Ziyuan
Ouyang Ziyuan (, born October 9, 1935) is a Chinese cosmochemist, geochemist and space advocate. He is a research professor at the Institute of Geochemistry of the Chinese Academy of Sciences. Asteroid 8919 Ouyangziyuan, discovered in 1996, was named in his honor. Career Ouyang was born in 1935 in Ji'an, Jiangxi. He obtained a degree in geology at the Beijing College of Geology and a doctorate in mineral deposits and geochemistry at the Beijing Institute of Geology. Thereafter, Ouyang spent many years conducting studies in deep mines. He later studied nuclear physics and worked in a particle accelerator laboratory. He later put forward a hypothesis on the formation of iron meteorites, an evolutionary model of the formation of the meteorites which fell at Jilin in 1976, and a theory of multi-stage cosmic ray radiation history. His works include ''Celestial Chemistry'', and he has published more than 160 scientific treatises. He was elected a Member of the Chinese Academy of ...

Cosmic Ray
Cosmic rays or astroparticles are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, and from distant galaxies. Upon impact with Earth's atmosphere, cosmic rays produce showers of secondary particles, some of which reach the surface, although the bulk are deflected off into space by the magnetosphere or the heliosphere. Cosmic rays were discovered by Victor Hess in 1912 in balloon experiments, for which he was awarded the 1936 Nobel Prize in Physics. Direct measurement of cosmic rays, especially at lower energies, has been possible since the launch of the first satellites in the late 1950s. Particle detectors similar to those used in nuclear and high-energy physics are used on satellites and space probes for research into cosmic rays. Data from the Fermi Space Telescope (2013) have ...

Chinese Space Program
The space program of the People's Republic of China is about the activities in outer space conducted and directed by the China, People's Republic of China. The roots of the Chinese space program trace back to the 1950s, when, with the help of the Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance, newly allied Soviet Union, China began development of its first ballistic missile and rocket programs in response to the perceived American (and, Sino-Soviet split, later, Soviet) threats. Driven by the successes of Soviet Sputnik 1 and American Explorer 1 satellite launches in 1957 and 1958 respectively, China would launch its first satellite, Dong Fang Hong 1 in April 1970 aboard a Long March 1 rocket, making it the fifth nation to place a satellite in orbit. China has one of the most active space programs in the world. With space launch capability provided by the Long March rocket family and four spaceports (Jiuquan Satellite Launch Center, Jiuquan, Taiyuan Satelli ...

The Chinese Lunar Exploration Program (CLEP; ), also known as the Chang'e Project () after the Chinese Moon goddess Chang'e, is an ongoing series of robotic Moon missions by the China National Space Administration (CNSA). Engineering Program The program encompasses lunar orbiters, landers, rovers and sample return spacecraft, launched using the Long March series of rockets. A human lunar landing component may have been added to the program, after China publicly announced crewed lunar landing plans by the year 2030 during a conference in July 2023. The program's launches and flights are monitored by a telemetry, tracking, and command (TT&C) system, which uses radio antennas in Beijing and antennas in Kunming, Shanghai, and Ürümqi to form a VLBI antenna. A proprietary ground application system is responsible for downlink data reception.

Power Plant
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the electricity generation, generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more Electric generator, generators, rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a Electrical conductor, conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, petroleum, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and use of renewable energy, renewables such as solar power, solar, wind power, wind, geothermal power, geothermal, and hydroelectricity, hydroelectric.

Nuclear Fusion
Nuclear fusion is a nuclear reaction, reaction in which two or more atomic nuclei combine to form a larger nuclei, nuclei/neutrons, neutron by-products. The difference in mass between the reactants and products is manifested as either the release or absorption (electromagnetic radiation), absorption of energy. This difference in mass arises as a result of the difference in nuclear binding energy between the atomic nuclei before and after the fusion reaction. Nuclear fusion is the process that powers all active stars, via many Stellar nucleosynthesis, reaction pathways. Fusion processes require an extremely large Lawson criterion, triple product of temperature, density, and confinement time. These conditions occur only in Stellar core, stellar cores, advanced Nuclear weapon design, nuclear weapons, and are approached in List of fusion experiments, fusion power experiments. A nuclear fusion process that produces atomic nuclei lighter than nickel-62 is generally exothermic, due t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helium-3
Helium-3 (3He see also helion) is a light, stable isotope of helium with two protons and one neutron. (In contrast, the most common isotope, helium-4, has two protons and two neutrons.) Helium-3 and hydrogen-1 are the only stable nuclides with more protons than neutrons. It was discovered in 1939. Helium-3 atoms are fermionic and become a superfluid at the temperature of 2.491 mK. Helium-3 occurs as a primordial nuclide, escaping from Earth's crust into its atmosphere and into outer space over millions of years. It is also thought to be a natural nucleogenic and cosmogenic nuclide, one produced when lithium is bombarded by natural neutrons, which can be released by spontaneous fission and by nuclear reactions with cosmic rays. Some found in the terrestrial atmosphere is a remnant of atmospheric and underwater nuclear weapons testing. Nuclear fusion using helium-3 has long been viewed as a desirable future energy source. The fusion of two of its atoms would be aneut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron
Iron is a chemical element; it has symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechan ...
