The Rubicon Space Systems 0.1N High Throughput (HT) Thruster is designed to use in space systems.

Rubicon's four 0.1N high throughput (HT) thrusters were successfully demonstrated in space from December 2022 through May 2023, accumulating more than 90 minutes of total firing (on) time and achieving expected nominal thrust and performance.

It was developed through a NASA SBIR Phase I/II/III program. To date, it has demonstrated over 3.1 kg throughput, over 17 hours of accumulated firing time, and over 65,000 pulses. Duty cycles have ranged from 10 – 90% in pulse mode, with pulse trains as long as an hour at nominal operating conditions.

The longest single pulse was 101 minutes at normal operating pressures and thrust. After all this testing, there are no signs of performance degradation. The successful development of the 0.1N thruster was a catalyst for Rubicon’s new developments and growth. Specific Impulse (Isp) was measured at >220s.
