In this SBIR Phase II project, Benchmark Space Systems proposes to build a resistojet micropropulsion system based on proprietarynbsp;warm gas generator technology. Results from Phase I of this project indicate that a system built around a resistojet thruster could increase specific impulse by up to 110% while remaining within the power budget of a typical CubeSat/SmallSat mission. That level of specific impulse would make the proposed propulsion system useful for Lunar and deep space missions, as well as enhancing the capabilities of low Earth orbit missions.The key advantages of the proposed system include:Unpressurized launch:nbsp;The system is launched unpressurized, and then pressurizes after a post-launch checkout. This eliminates risk associated with pressurized launches.Long Term Storage:nbsp;Since the system does not need to be pressurized until thrust is required, it can sit in a quiescent state for up to 2 years with no performance degradation or propellant lost to leakage.High Thrust:nbsp;The system is capable of operating at thrust levels up to 1N, making it viable for impulsive maneuvers.Low Cost:nbsp;The system is based around commercial-off-the-shelf components and a low-cost propellant, making it attractive for both NASA and commercial customers.This technical effort will take the concept evaluated and tested in Phase I and bring it to a flight-ready propulsion system that can be inserted into a range of upcoming commercial, DoD, or NASA technology demonstrations.
