Dawn Aerospace

Dawn Aerospace is a space transportation and spacecraft propulsion company founded in 2017, with operations across New Zealand, the Netherlands, France and the United States.^[1] The company develops non-toxic, nitrous-oxide and propylene chemical propulsion systems for satellites and reusable suborbital launch vehicles.

The SatDrive is a turn-key propulsion system for satellites in the roughly 30 kg to 500+ kg class, integrating thrusters, tanks, valves and control electronics.^[2] The CubeDrive is a 0.8U integrated unit for CubeSat-class spacecraft.^[3] B-series thrusters span the 1 N, 5 N, 20 N and 200 N thrust classes.^[4] As of May 2026, Dawn Heritage page records 207 thrusters operating on 51 satellites in orbit, including 22 SatDrive and 12 CubeDrive systems.^[5] Customers include Pixxel, Sidus Space, Blue Canyon Technologies and BRIN, among others, and its propulsion systems are used on Earth-observation satellites alongside other space applications.^[3]

The Aurora spaceplane is a remotely piloted, reusable rocket-powered aircraft for suborbital payload campaigns. Dawn describes a top speed of Mach 3.7, a maximum altitude of 100 km, a 15 kg payload capacity and a four-hour turnaround time on the dedicated Spaceplane page;^[6] the Dawn homepage quotes 10 kg payload capacity.^[7] Aurora has carried the Arizona State University LEO-TIMS thermal-infrared camera on an Earth-imaging flight^[8] and the Scout Space Morning Sparrow space-domain-awareness payload on a surveillance test flight.^[9]

Dawn Aerospace's relevance to Earth observation is ancillary: its propulsion systems enable satellite orbital manoeuvring and deorbit for EO spacecraft operators, while Aurora provides a suborbital platform for payload testing and sensor demonstration.
