Samantha Hurley is a PhD candidate focusing in MicroCathode Arc Thruster (µCAT). She received her BS and MS from The George Washington University in Mechanical and Aerospace Engineering. In addition, she is a PATHWAYS intern at NASA Goddard working for the Satellite Servicing and Capabilities Office. She is designing a linear actuator system; this is a new version of the µCAT. The system replaces the spring-feed mechanism with a stepper motor to feed the cathode forward as it ablates. The motivation behind this change is that a longer cathode can be used in order to increase lifetime, there will be precision feeding via step control, an increase to the thrust over power ratio, and a magnetic coil is not necessary omitting any possibility of unwanted torque or interference with the satellite.

Sungrae received his Master’s degree in Mechanical & Aerospace Engineering from The George Washington University. His research was focused on design of air-breathing hall-effect thrusters. As a PhD student, Sungrae is continuing his research of air-breathing hall-effect thrusters that could one day be used in the Martian atmosphere.

Li's research area is the physics of plasma. He is researching the behavior of cold atmospheric plasma (CAP) jet under different conditions. For example, He is examining how a CAP jet is affected by external electric fields, magnetic fields, and how it interacts with other objects such as nano particles. In a recent experiment, Li studied the CAP jet in an axial DC electric field. The electric field was generated by applying varying values of electric potential to a copper ring. Regarding plasma diagnostics, Li measured several quantities: (1) the electron density was measured using the Rayleigh Microwave Scattering (RMS) method, (2) the plasma bullet behavior was observed using an Intensified Charged-Coupled Device (ICCD) camera, and (3) the chemical species in the jet were identified by analyzing the jet spectra using a spectrometer.
