Outer Planet Missions with Electric Propulsion Systems—Part I

Abstract EN

For interplanetary missions, efficient electric propulsion systems can be used to increase the mass delivered to the destination.

Outer planet exploration has experienced new interest with the launch of the Cassini and New Horizons Missions.

At the present, new technologies are studied for better use of electric propulsion systems in missions to the outer planets.

This paper presents low-thrust trajectories using the method of the transporting trajectory to Uranus, Neptune, and Pluto.

They use nuclear and radio isotopic electric propulsion.

These direct transfers have continuous electric propulsion of low power along the entire trajectory.

The main goal of the paper is to optimize the transfers, that is, to provide maximum mass to be delivered to the outer planets.
