A Driving Force in Satellites
ExoTerra offers complete propulsion solutions based around our flight-proven Halo and Halo 12 miniature Hall-effect thrusters. Halo systems are inherently flexible, allowing the use xenon or krypton propellants to suit mission requirements and budgets.
ExoTerra's Iris is a fully-integrated COTS electric propulsion module for smallsats. Iris incorporates our flight-proven Halo thruster, weighs a mere 15kg (wet), and fits within the normally unused space inside common 24" diameter separation rings.
ExoTerra's power systems include radiation-tolerant, lightweight, high-efficiency power processing and distribution units. Halo PPUs are fully throttleable and highly autonomous, and support the simultaneous operation of multiple thrusters.
ExoTerra's Propellant Flow Control system delivers precisely-controlled propellant flows to electric thrusters. Its compact size (<1U) and flexibility make it the perfect choice for electric propulsion systems using xenon or krypton propellants.
ExoTerra's Courier is a complete CubeSat bus built around our flight-proven Halo thruster. Courier provides >1200 m/s dV, 300W, and 2U of payload in a 12U form factor, with >300 W electrical power available to payloads during non-thrust periods.
ExoTerra's Courier 4000 is the larger counterpart to the Courier bus. Built around one or more Halo 12 Hall-effect thrusters, Courier 4000 can be configured as a satellite bus, small launcher upper stage, or GEO, lunar, or interplanetary boost stage.
ExoTerra can deliver custom-configured, fully-integrated and tested propulsion modules to meet specific spacecraft requirements. We can also provide complete propulsion systems as discrete components for integration by the customer.
