Colloid Micro-Newton Thruster Development for the ST7-DRS and LISA Missions

Abstract: We present recent progress and development of the Busek Colloid Micro-Newton Thruster (CMNT) for the Space Technology 7 Disturbance Reduction System (ST7-DRS) and Laser Interferometer Space Antenna (LISA) Missions. ST7-DRS is a NASA New Millennium Program technology demonstration mission and part of the ESA LISA Pathfinder Mission. The LISA Mission is a joint NASA/ESA mission scheduled to launch in the next decade. These drag-free missions require precision microthrusters to provide lownoise spacecraft positio… Show more

“…The Darwin infrared space interferometer and the Laser Interferometer Space Antenna (LISA) [1] are examples of missions that require technology capable of producing 0.1 to 1000 N of thrust with low thrust noise and high thrust precision. Two ideal candidates that could meet the thrust requirements are the colloid micronewton thruster (CMNT) and the field emission electric propulsion (FEEP) thruster [1][2][3]. CMNT and FEEP thrusters are unique in that they do not require a cathode for propellant ionization.…”

“…However, any miniaturization only achieves its full potential if its merit is not outweighed by the mass and volume required by auxiliary propulsion components in the propulsion system. While advances have been made in the miniaturization of auxiliary components such as the Busek Microvalve used for the colloid thruster system on LISA Pathfinder [91], the propellant stored itself constitutes a natural barrier towards miniaturization. Any meaningful miniaturization of a thruster technology therefore needs to consider the entire propulsion mass, highlighting the importance of maintaining, or increasing, the propulsion system efficiency with advancing miniaturization.…”

“…Charged droplets are generated by applying a strong electrostatic field and extracted to generate thrust. Colloid propulsion technology has advanced significantly during the last decade, through the development of the thrusters for NASA's ST-7 [23] and the Laser Interferometry Space Antenna missions [24]. The technology leveraged from the ST-7 design is now available for use in nanosatellites [25].…”
