Thermasat thruster


The ThermaSat thruster offers a high thrust, simple, and safe mobility solution for an in-space economy. The rise in proliferated LEO constellations, servicing vehicles, and debris mitigation regulations will necessitate a propulsion system that adapts to this changing environment. Rapid response and deployment will be critical in maintaining constellations and space superiority.

ThermaSat provides a solution for a more sustainable space economy through rapid mobility and a propellant with superb safety and availability.



ROAMER is a multipurpose orbital servicing vehicle utilizing ThermaSat propulsion technology.

With the ability to be refueled with water, ROAMER will be located around space stations. ROAMER vehicles can assist with station inspections, assembly, and docking of satellites.

The water based and low-pressure propulsion system poses little risk to human crew and costly assets.

Positioning ROAMER around a central hub allows it to be refueled and supplied with the ability to venture into different orbits to perform servicing, refueling, removal of debris, and repositioning satellites without propulsion systems.


ThermaSat Plus takes SmallSat
Technologies to New Level


With performance metrics matching that of nuclear thermal rockets, ThermaSat Plus can deliver cargo throughout LEO, GEO, cis-lunar space and beyond.

This work-horse is designed to be the most sustainable and efficient orbital transport vehicle (OTV) that ensures total space superiority.


HotSwap Milestone 3 Render 3

Update and Maintain In Orbit

ThermaSat’s HotSwap Technology consists of ISAM removable cartridges that are secured into a ThermaSat HotSwap bus.

This allows satellite subsystems to be rapidly replaced in orbit to update payloads or fix broken subsystems.

ThermaSat provides an unparalleled capability and a unique thermal propulsion approach for maneuvering in space.

With nearly unlimited configurations and operational concepts ThermaSat’s family of systems offer unmatched capabilities enabling more space missions, more space assets, and more space-based capabilities at a fraction of the cost.
