A new specialized electrospray thruster with a potential to be used with a 3-U CubeSat was operated. The key difference between this thruster from traditional colloid thrusters is the porous stainless steel surface used for the emission sites. With this porous surface the actual location and number of the Taylor cones changes with varying fuel flow. The understanding of these formations is discussed with low, moderate, and high flow rates. The limitations of the experiment equipment and observed system response are discussed. Due to these limitations, the colloid thruster was only able to operate in the low mass flow rate regime.
