Hypergolic bipropellant engine
A higher-thrust engine in development that mixes hydrogen peroxide with a proprietary fuel that ignites on contact, targeting up to 500 N.
Why it matters
Docking and lunar landing need fast, precise pulses of high thrust. A green fuel pair that self-ignites could do that without hydrazine.
How the technology works
The engine combines hydrogen peroxide with a hypergolic fuel, so the two ignite on contact and can pulse rapidly. Arkadia is funding development with its 2026 European Innovation Council package and sees uses including lunar landers.
