Overview

The Ascend propulsion system is a family of fully integrated thermo-resistive, water-based propulsion solutions. Generating thrust using superheated steam, it ensures a safe, robust, and exceptionally reliable propulsion. Engineered as a plug-and-play subsystem, it combines the best aspects of the various propulsion technologies, offering substantially higher thrust than electric propulsion, along with greater simplicity and reliability than chemical thrusters. Ideal for end-of-life de-orbiting applications, its high performance and modularity also makes it a prime choice for other maneuvers, including orbit raising, collision avoidance, and formation flying. Thanks to Ascend Beyond Space's technological advancements, this propulsion system achieves superior thrust and specific impulse, establishing it as the leading water-based propulsion system on the market. Designed for high reliability, with extensive direct and indirect fluidics, electrical, sensor redundancy, making it fully compliant with launcher and ground-safety requirements from all major launch authorities.
