| Popis: | Onboard spacecraft power and propulsion are two of the essential utilities provided on a spacecraft. Together, these two subsystems can comprise one-half to over three-fourths of the launch mass of a spacecraft. What is not often realized is that there is a synergism between spacecraft power and electric propulsion. Studies by NASA and other organizations have consistently shown that advanced space power technologies complement advanced electric propulsion technologies. Awareness of this synergism is beginning to be noticed in designs of next-generation communications satellites and scientific spacecraft. This paper highlights some of the emerging NASA-sponsored space power and electric propulsion technologies that can benefit both commercial and scientific spacecraft by reducing the mass fractions of these utilities by 50 percent or more.
