The Exploration of the Solar System

southwestern tip of Portugal, what we would now call an Institute of Maritime Research. This date conveniently marks the commencement of the heroic age of oceanic exploration and of our understanding of the geography of this planet. Under Henry's sponsorship, the Portuguese captains discovered the Canary and Cape Verde Islands and sailed as far south as Sierra Leone, dispelling medieval terrors...

Electric Propulsion for Solar System Exploration

The use of ion propulsion for deep-space missions will become a reality in 1998 with the  ight of the ion-propelled, New Millennium Deep Space 1 (DS1) spacecraft. The anticipation of this event is stimulating the call for improved ion propulsion technologies, a trend that is expected to continue. This paper describes the evaluation of possible advanced solar electric propulsion technologies an...

Study of the performance of a solar adsorption cooling system

This article presents a transient model of a solar adsorption cooling system. A computer program has been developed to simulate the operation of a two bed silica gel- water adsorption cooling system as well as flat plate collectors and the hot water storage tank. This program is then utilized to simulate the performance of a sample solar adsorption cooling system used for cooling a set of r...
