This assessment was requested by the NASA Engineering and Safety Center (NESC) Guidance, Navigation, and Control (GN&C) Technical Discipline Team (TDT), which identified the topic as an unrecognized critical need for the Agency’s future space science observatory-class space platforms. An initial low-fidelity feasibility study of the use of cold-gas micro-thrusters as a replacement for reaction wheels was performed in 2017 as a GN&C TDT discretionary activity. The assessment documented in this final report was initiated in 2018 as a follow-on high-fidelity study.
