The technology of electric propulsion evolved to overcome the high propellant weight associated with propulsion by chemical means. As opposed to ejecting propellant at velocities of kilometers per second, exhaust velocities of plasma at tens of kilometers per second and more could be accomplished through electrical means. Although higher exhaust velocities require higher on-board power, the reduced propellant requirements facilitate a large variety of space transportation missions, such as orbitraising, stati…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
