Sleiman Yammineerefore, it is necessary to use space insurance to protect against potential risks and reduce the possibility of economic losses. When risks occur, the project can receive compensation from space insurance. For the insurance industry, space travel is a new field, and it is expected that by 2040, the

A. Lascouxraft. The primary motivation for the development of electric thrusters is the increase in the specific impulse which is a measure of the utilization of propellant mass. Electric spacecraft thrusters are generally grouped into three categories based on the main heating mechanism: electro-thermal, ele

This chapter addresses the ionospheric manifestation of geomagnetic storms induced by solar wind. Changes in the electron

Danielle Sallesance between the energy acquired by the solar radiation absorbed and the energy lost to space by the emission of heat radiation. The interaction of this radiation with the climate system is complex but it is clear that any change in total solar irradiance (TSI) has the potential to influence climate

An Improved Spider Monkey Optimization for Solving a Convex Economic Dispatch Problem,algorithm is called multidirectional spider monkey optimization algorithm (MDSMO). The proposed algorithm can accelerate the convergence of the proposed algorithm and avoid trapping in local minima. The general performance of the proposed MDSMO algorithm is tested on a six-generator test system for
