ExoTerra's Courier is a 12U solar electric propulsion module offering up to 1270 m/s and 2U of payload capacity in a 12U CubeSat. It uses the Halo electric propulsion system, known for its compact size and low weight, and is powered by ExoTerra's Fold Out Solar Arrays (FOSA), which generate 296 W and are mounted on a single-axis gimbal for increased power. The 100 kRad radiation-tolerant Electric Power System efficiently bridges power and propulsion, delivering reliable power to spacecraft components.
The Courier provides 2U of payload space for customers, with extra power available for high-power instruments and communications equipment when the Halo thruster is not in operation, enabling advanced applications not possible with other CubeSat buses.

Courier 4000

ExoTerra’s Courier 4000 is a high-impulse solar electric propulsion module that enables microsatellite transfers from LEO to GEO, cislunar, and interplanetary destinations, using a dedicated small launch vehicle.

Courier 4000 offers a ∆V of 6000-11,000+ m/s, allowing mission orbit optimization, inclination adjustments, orbit altitude raises, and safe deorbiting at end of life. Its high specific power solar arrays provide up to 1500 W to the payload when the thruster is inactive, enhancing payload performance and telecommunications. The module's 100 kRad electronics ensure extended mission lifetime and reliability.

A bus module can be added to transform the stage into a full spacecraft bus for GEO or interplanetary missions, improving telecommunications, command and control, and GN&C capabilities. Contact ExoTerra for details.
