A Multi-Spacecraft Multi-Objective Interplanetary Global Trajectory Optimization Transcription

Completed Technology Project

Project Introduction

We propose to enhance GSFC’s interplanetary mission design capability by designing a fully automated multi-spacecraft multi-objective interplanetary global trajectory optimization transcription. Advanced trajectory design technologies including the ability to design Distributed Spacecraft Missions (DSMs) are attracting increased interest but no mission design tool is currently capable of performing mission and systems design/optimization for an interplanetary DSM. This effort will deliver a software prototype capable of building the optimal design of a DSM-class mission where multiple spacecraft depart to the heliocentric regime from the same launch vehicle to perform coordinated science. This new capability will lay the groundwork for a follow-on proposal to implement this new capability into NASA Goddard's Evolutionary Mission Trajectory Generator (EMTG) where it will enable new announcements of opportunity for Distributed Spacecraft Missions.
