5N High Throughput (HT) Thruster

Technical Overview

The 5N HT thruster design enables a high throughput of propellant and long firing times. It shares much of the same components and design as the 5N LT thruster, but the reactor is upgraded with ultra-high temperature materials. 

The first 5N HT thrusters will be assembled in late 2023 with the qualification campaign expected to be in early 2024.
