Design of a Green Monopropellant Propulsion System for the Lunar Flashlight Mission

2019-12-12 , Andrews, Dawn , Lightsey, E. Glenn

The Lunar Flashlight Mission is a lunar-bound small satellite that will investigate the Moon’s poles for water ice. Aboard the spacecraft is a green monopropellant propulsion system that has been designed by the Georgia Institute of Technology under sponsorship and guidance by the NASA Marshall Space Flight Center. Green monopropellant propul sion is a forthcoming technology that promises improvements in performance and safety over existing monopropellant systems such as Hydrazine, making it a very desirable new technology, and Lunar Flashlight will be the first mission to utilize this propulsion on a CubeSat platform. The design solution for the Lunar Flashlight Propulsion System will be shared, as well as the story behind its evolution through the design process. Additionally, several key aspects of its design that are fundamental to green monopropellant propul sion will be collected in contribution to a design methodology for future iterations. This project is intended to continue on to launch with the Artemis-1 Mission, at which point the propulsion system would complete its objectives of contributing flight heritage to this technology while acting as a critical component for the Lunar Flashlight Mission.
