Physical Investigation of Space, Dosimetry of Space Ionizing Ray Effect (Van Allen belts, Galactic Cosmic Rays and Solar particles) and Plotting Dose Map for Satellite Circular Missions
One of the main factors for satellite design is simulating of total ionizing dose due to space ionizing rays in devices used in space. By measurement of induced dose based on available data in different altitudes, expenses of designing, satellite weight and amount of needed fuel will be reduced. Optimum design of satellite for protecting satellite against ionizing radiation has considerable eff...
متن کاملComputation of cosmic ray ionization and dose at Mars: a comparison of HZETRN and Planetocosmics for proton and alpha particles
The ability to evaluate the cosmic ray environment at Mars is of interest for future manned exploration. To support exploration, tools must be developed to accurately access the radiation environment in both free space and on planetary surfaces. The primary tool NASA uses to quantify radiation exposure behind shielding materials is the space radiation transport code, HZETRN. In order to build c...
متن کاملSpace Environment and Evaluation of Typical High Altitude Satellite
The space environment consists mainly of high-energy charged particles, such as protons, electrons and heavy ions. They are originating from several sources including galactic cosmic radiation, solar flares and van Allen belts. High energy electromagnetic radiation and neutrons have also been measured on spacecraft. Although shielding can reduce the effect of space radiation it cannot be elimin...
متن کاملEnergies of Cosmic-Ray Particles
Cloud chamber photographs of cosmic-ray tracks in a magnetic field up to 17,000 gauss are shown. On the assumption that the particles producing the tracks are travelling downward through the chamber rather than upward, particles of positive charge appear as well as electrons. From the specific ionization along the track it is concluded that the positives are protons, and are not nuclei of charg...
متن کاملManned - Unmanned Vehicles Convoy
This paper describes the project undertaken by DSO National Laboratories to demonstrate convoy movement involving a manned vehicle and two Unmanned Ground Vehicles (UGVs) along roads and dirt tracks at speeds up to 35 km/h and 20 km/h respectively. The project work included development of UGV hardware, vehicle controller, sensor suite comprising of short and long range sensors, and high speed n...
