According to foreign media reports, NASA's advanced aerospace propulsion system researchers demonstrated the feasibility of a nuclear rocket as a propulsion system at the Marshall Space Flight Center. The use of non-nuclear fuel to simulate a nuclear rocket power system has helped the progress of this technology. Humans solve the dynamic problem of flying to Mars and other star systems. The nuclear power system cryogenic advancement research group hopes to use three years to study the nuclear power technology of space flight. Because the nuclear rocket material will face extremely high temperatures, it is necessary to make breakthroughs in this area. This technology can also bring about spacecraft. Strong driving force is more effective than conventional chemical rocket motors.
The nuclear rocket system can greatly shorten the time to fly to Mars and help reduce the time that astronauts are exposed to cosmic rays.
The research team tested the components of various materials through the nuclear rocket element simulator. The final nuclear power prototype element would include uranium, but no radioactive material was involved in this test. Scientists used graphite composites and "cermet" composites as materials that were previously investigated by NASA and the Department of Energy. The use of nuclear rockets as aerospace power is not a completely new concept. NASA conducted research on the power of this future spacecraft from 1955 to 1973, and conducted feasibility tests. As a result of the launch of the Manned Landing Mars Project, testing was stopped and new construction was conducted. The simulation facility mainly studies fuel elements and materials and simulates the working environment of space nuclear propulsion systems, such as materials that can withstand extreme conditions of 2760 degrees Celsius and 1000 pounds per square inch of pressure.
Mike Hortz, project leader of the nuclear power system at Marshall Flight Center, believes that these tests will help us reduce the development risk and related costs of nuclear-powered rockets. The first-generation nuclear-powered cryogenic propulsion system has a greater thrust than a chemical-energy rocket, which can shorten space flight time, reduce the time that astronauts are exposed to harmful rays during space flight, and promote the human landing Mars program. In addition, the nuclear power system can also transport large-capacity payloads to lay the foundation for the development of more advanced aerospace power systems. Humans must make greater breakthroughs in the power system when entering deep space.
A prism is a transparent optical element with flat, polished surfaces that refract light. At least two of the flat surfaces must have an angle between them. The exact angles between the surfaces depend on the application,prism: In optics, piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light.
Dispersive prism can be used to break light up into it's constituent spectral colors(the color of the rainbow).Furthermore, prisms can be used to reflect light or to split light into components with different polarizations.
Optical Prism include Right angle prism.Equilateral dispersing prism.Dove Prism.Corner Cube Reflectors.Beamsplitter, Powell prism, dove prism, wedge prism, penta prism etc.
