Dawn’s single-thruster CubeSat Propulsion Modules range from 0.8U to 2U+ in size. They include a single B1 Thruster, tanks, valves, and control electronics. The structure is additively manufactured as a single monolithic piece per ECSS standards and includes both fuel and oxidizer tanks. Health monitoring instrumentation includes integrated and isolated thermocouples, pressure sensors.
Utilizes nitrous oxide (N2O) and propene (C3H6), which are safe to handle and widely available, unlike ADN or HAN.
Propellants are self-pressurizing and don't require complex controls or moving parts to maintain performance.
Delivers 285 s of Isp, similar to bi-propellant hydrazine-based alternatives, but with less mass and smaller volume.
Suitable for any CubeSat:
Dawn can provide stand-alone thrusters or a complete propulsion system including tank, feed, and instrumentation & control.
- Dawn Aerospace
- Based in New Zealand, the Netherlands, and the United States, Dawn Aerospace is a space transportation company building non-toxic satellite propulsion systems and same-day reusable launch vehicles. Non-toxic, high-performance, and turn-key propulsion systems for CubeSats, ESPA, and ESPA-Grande satellites. For small satellites, they simplify systems and replace the poisonous and highly-regulated fuel, hydrazine. For CubeSats, they increase capabilities by supplying 1,000x higher performance than electric-based propulsion systems. Same-day Reusable Launch Vehicles that do not require specialized space-launch infrastructure, integrate with everyday aircraft in nearby airspace and launch as often and routinely as commercial aviation. By building these technologies in tandem, Dawn is creating the end-to-end architecture required for delivering, positioning, and returning spacecraft in a highly scalable and environmentally conscious way.
