The Energetic Transient Array (ETA) is a mission, proposed by the Center for Space Research (CSR) at MIT, to set up an interplanetary constellation of six microsatellites for Gamma Ray Burst (GRB) astrometry. The micro-satellites will be deployed into distinct heliocentric orbits by a carrier spacecraft which will be propelled by a stationary plasma (SPT-79) electric thruster. This paper presents a discussion of the issues related to the application of electric propulsion technology in a primary propulsion mode. An overview of the mission is given. The results of a trade study, performed to assess various propulsion options, show that the SPT-70 is best suited to meet ETA system requirements. A constellation deployment scenario has been developed around the operation of two SPT-70 thrusters in serial mode. Details of SPT-70 system hardware are presented together with system block diagram and configuration. ETA is a unique opportunity to demonstrate the operation of electric propulsion technology in an interplanetary setting and in the mode of primary propulsion.
