OhmSpace

OhmSpace is pioneering next-generation resistojet propulsion with a novel 3D-printed resistive element, capable of enduring thousands of high-temperature cycles—surpassing typical customer mission lifetimes. Our resistojet technology supports a wide range of propellants, including water, ammonia, xenon, krypton, and other inert gases, offering unmatched operational flexibility.

Our flagship product, STAR-Water-nano, is a plug-and-play, ultra-compact propulsion system designed for both nano/microsatellite missions in LEO and secondary propulsion needs on GEO telecommunications satellites. With a low-pressure tank, modular architecture, and streamlined AIT requirements, it ensures fast integration and reduced mission costs.

Set for its first in-orbit demonstration in Q1 2026, STAR-Water-nano offers high performance with:

• Isp > 200 s
• Thrust up to 20 mN
• Total Impulse from 600 Ns
• Power up to 50 W
• Tank capacity from 0.3 kg
• Compact sizing from 2U

Delivering up to 10x faster ROI than Hall-effect thrusters and 100x quicker maneuvers than FEEP, our technology marks a step change in electric propulsion performance and integration simplicity.
