Orbion raises $9.2M to mass-produce plasma thrusters for small satellites

Michigan-based startup Orbion has secured $9.2 million in Series A funding, which it will use as it undertakes the mass-produced manufacturing of its plasma thrusters for use in small satellites. Orbion’s thrusters are Hall-effect thrusters, which use an electric field to accelerate their propellant and create thrust. Hall-effect thrusters are nothing new, but Orbion’s approach, which uses plasma propulsion, has not previously been available at a cost and volume affordable for smaller satellite operators.

Just as SpaceX has greatly reduced the cost of launch services, Orbion aims to take a technology that was once reserved for the elite few, who could spend hundreds of millions or more on launching gigantic, train car-sized satellites into orbit. That basically limited the addressable market to government, defense and some very deep-pocketed commercial clients.

It’s a shame because plasma propulsion is a fundamental necessity for some types of satellite operations, regardless of budget – and it’s also a much more propellant-efficient method vs. other potential options, and will even enable satellites to have longer operating lives before they fall out of orbit and therefore out of service.

The small sat and cube sat boom we’ve seen and are seeing is due in large
