Our Technology

Technology-OhmSpace

Our innovation allows extreme temperatures for thousands of heating cycles as required by typical mission requirements. We developed high temperature resistojets through a new design enabled by 3D printing.

Our resistojet technology offers a previously unseen combination of efficiency, low cost and reliability.

Our resistojet technology offers a previously unseen combination of efficiency, low cost and reliability.

We advanced resistojets to the ultimate stage, a propulsion technology that heats a propellant electrically with a resistive element, at temperatures as high as 2,400 K.

We have unlocked very high-temperature operation with multiple propellants, including water, ammonia, and inert gases.
