The B1 Thruster assembly includes the thruster body, valves, and control electronics. The thruster body is additively manufactured as a single structure using Inconel 718 and includes the injector, combustion chamber, and nozzle. Health monitoring instrumentation includes an integrated and isolated thermocouple and chamber pressure sensor. With standard data and power interfaces, thrusters are easy to command and operate.

Available in a variety of form factors, the B1 Thruster is currently used in the following arrangements within Dawn systems:
- One thruster in the center of Dawn’s single-thruster CubeSat Propulsion Modules.
- Four thrusters, mounting in each corner of Dawn’s four-thruster CubeSat Propulsion Modules.
- Eight thrusters on a single system positioned to allow for full 6-axis spacecraft control.
- A modular building block for customized propulsion systems, with absolute freedom on positioning and mounting.

Power Consumption:
- Hit: 12 W (for 50 ms)
- Hold: 0.8 W
- Igniter: 9 W (for 50 ms)
