Reimagining the way orbital rockets are built and flown.

AEON 1

gradient-overlay-v4.jpg

Extraordinary engine performance.
Designed for automation.
<100 components.

 

Propellants of the future: oxygen + methane.

Enhanced mission reliability by simplifying engine igniters, turbopumps, reaction control thrusters, and vehicle pressurization systems.

As a bonus, these propellants are the easiest to eventually make on Mars.
