Recent and numerous failures of reaction wheels have cut short and/or limited the mission functions of several spacecraft including DAWN, Mars Odyssey, and Kepler among others. A micro Newton impulse-bit hydrazine thruster has the potential to backup or even replace reaction wheels on most missions, thereby extending mission life. This paper will discuss the development and test of a plug-and-play hydrazine thruster with 30 – 130 milliNewton thrust levels, and impulse bits < 50 microNewton-sec. In addition, this paper will address mission applications that include backup for, or even replacement of reaction wheels, delta-V thrust for CubeSats, and primary attitude control for the 20 – 50 kg class of spacecraft.
