Abstract:All space vehicles require some source of power for operation of the instruments and the radio communication equipment which makes possible the remote recording of the data obtained. Current satellites and space probes require relatively low power; for example, Pioneer V, whose data were recorded at distances up to 221/2 million miles from the earth, carried out its mission with a power of 30 watts.Many satellites use chemical energy stored in nickel-cadmium or silver-zinc base batteries, which have a limited … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research 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 students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
