ExoTerra Resource

ExoTerra Resource is a Littleton, Colorado-based space propulsion company specializing in miniaturized Hall effect thrusters (HETs) and supporting propulsion hardware for small satellite and CubeSat missions. The company focuses on delivering high-impulse electric propulsion in compact form factors that are accessible for commercial and government microsatellite operators.

ExoTerra's core product is the Halo Hall effect thruster family — lightweight, compact HETs designed for CubeSat and microsatellite platforms that require significant delta-V capability within tight volume and mass constraints. Complementary products include propellant distribution systems (PDS) and power processing units (PPUs) that form complete propulsion subsystems.

The company targets the growing demand for capable propulsion systems that can fit within the mass and volume limits of small satellite buses, enabling orbit-raising, constellation management, deorbit, and deep-space missions for cost-constrained programs.
