Earth revolution synchronous orbits and aero-gravity assists to enhance capabilities for interplanetary missions by sub-payload spacecraft

Abstract

This paper proposes a strategy for sub-payload spacecraft to extend possibility of interplanetary exploration without interrupting the mission by the main spacecraft. Combination of Earth revolution synchronous orbits and aero-gravity assists at Earth will allow sub-payload spacecraft to control its departure timing, C3 energy and destination independently. A case study of a possible sub-payload bound for Mars is shown and a preliminary mission sequence is presented. Show more
