On the Use of Subcarriers in Future Space Missions

Deep space missions and the issue of overcoming the problem of space radiation

As a member of the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), Iran has a long-term space exploration program. Space radiation is one of the challenges facing humans when they go outside Earth's protective atmosphere and magnetic field. Space is an environment that the cardinal principles of radiation protection i.e. time, distance and shielding cannot be effectively ...

Future role of vitamin C in radiation mitigation and its possible applications in manned deep space missions: survival study and the measurement of cell viability

Background: Astronauts will be exposed to both chronic space radiation and acute high doses of energetic radiation of solar particle events in long-term deep space missions. The application of radioprotectors in space missions has basic limitations such as their very short time window as well as their acute toxicity and considerable side effects. The aim of the present study was to investigate ...

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...

آینده‌پژوهیِ تبارشناسانه (رویکردی شایسته در آینده‌پژوهیِ پدیده‌های جغرافیایی)

This article tries to focus on the genealogy of Foucault, and by putting it in connection with future studies, try to introduce genealogical future studies as a qualified methodology in geographical research. Accordingly, if the geographic space, relational space, and scenes role playing of discourses and relations of power and knowledge is considered, we face the object and subject of a discou...
