In September 2015, NASA selected five mission concepts from a field of 27 to proceed to the next stage (step 2) of the latest Discovery mission competition. Each team submitted a Mission Concept Study to NASA in August 2016, and in January of 2017 NASA selected Psyche and a second mission for flight. This paper describes Psyche, a unique investigation of a metal world, which is the only one of the original five mission concepts studied in detail to propose the use of Electric Propulsion (EP) to…

Development of the Psyche Mission for NASA ’ s Discovery Program

In January 2017, the proposed mission Psyche: Journey to a Metal World, led by principal investigator Dr. Lindy Elkins-Tanton of Arizona State University (ASU), was selected for implementation as

A Margin Management Strategy for Low Thrust Trajectories on the Psyche Project

An overview of the margin management process for Psyche is presented, and how it has evolved from the early proposal stage to its current state, culminating in a new margin strategy that enables optimization across many of the system elements, and will serve as a template for future deep space SEP missions.

Overview of the spacecraft design for the Psyche mission concept

The Psyche mission concept is presented, and the unique architecture that enables the use of commercially developed electric propulsion and space power systems from Space Systems Loral to provide flexibility in mission design is presented.

Evolution of the Preliminary Fault Management Architecture and Design for the Psyche Mission

This paper describes the evolution of the Psyche fault management architecture and design from the concept study into the preliminary design phase, with a focus on the unique challenges associated with flying GEO communications satellite hardware in deep space, implementing a robust low-thrust mission, and the integration of design philosophies and hardware from JPL and Maxar.

An Approach to Magnetic Cleanliness for the Psyche Mission

This paper describes the derivation of a set of magnetic cleanliness requirements directly derived from the magnetometer science performance and Psyche's range of expected fields, and more generally the processes and procedures that govern the magnetics program for Psyche.
