The Rubicon Space Systems 1N High Throughput (HT) Thruster is designed for propulsion applications in space systems.

It leverages processes developed within the 0.1N thruster program and is in active development toward flight qualification. Through a US Space Force SPRINT BAA, Rubicon developed an instrumented 1N HT thruster to demonstrate these design processes and relative thermal characteristics, achieving record throughput and performance, accumulating over 1.4 hours of firing time, and ~1.6kg throughput, and more than 5700 pulses.

Rubicon Space Systems is now on pace to complete flight qualification of the 1N HT thruster in early 2024 and a target throughput of 20kg. Specific Impulse (Isp) was measured at >250s.
