w w w . b u s e k . c o m Technically mature, low pressure, non-toxic electrospray system for high delta-V CubeSat propulsion BET-1mN Electrospray Thruster The Busek Electrospray Thruster system is the result of over 10 years of pioneering research and development, enabling a new class of CubeSat and NanoSat missions. The 8.5 cm x 8.5 cm x 6 cm module consumes under 15W power to deliver a thrust up to 1.0mN, at ISPs ranging from 400 s to over 1300 s. The in-situ optimization of performance output provides significant mission flexibility and versatility. The Electrospray Thruster System features a precision micro-valve, leveraged from ST7 design heritage, and rugged flight electronics. • 50mL propellant reservoir, 100mL reservoir, or custom volumes are available • Integrated DCIU enables communication via UART • Propellant-less field emission cathode neutralizes the positively-charged electrospray plume, minimizing risk of spacecraft interception. • Tank is at low pressure • Safe, non-toxic, non-volatile propellant • Complete System Precision Miniature Valve
