A Driving Force in Satellites

Abstract Background

Our Services,
Your Solution

With our extensive aerospace experience, ExoTerra can create the right electric propulsion solution for your spacecraft needs.

Our Products

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.
