ABOUT OUR COMPANY
The first ecosystem of equipment tailored for satellite end-of-life management.
With the booming space industry, space debris is growing exponentially, threatening access to space and vital services like communication, navigation and natural disaster management. The solution? Responsible disposal of space assets at end-of-mission, now a legal requirement since 2022.
To that end Ascend Beyond Space offers the first complete and accessible ecosystem of compatible and complementary equipment designed for this purpose, providing a sustainable solution to the growing challenge of space debris.
OUR PRODUCTS
Our range of "plug & play" preventive solutions.
Installed on ground, excelling in space.
Single-use, fully electrical switch tailored for battery passivation through disconnection and active depletion.
Handling up to 50 amperes with a highly competitive size ensuring a seamless integration in a wide range of spacecrafts.
SPARK Battery Passivator
Single-use fully electrical switch tailored for solar array disconnection at end of mission. Best cost-effective and accessible choice for integrators seeking a convenient and affordable means to passivate solar panels.
ECLIPSE Solar Array Passivator
GARNET Pressure Transducer
Combined pressure and temperature sensor designed as a seamless plug-and-play subsystem. Enabling assessment of propellant levels and propulsion system health throughout the complete mission lifetime, and at end-of-life stages.
HOOVER Isolation Latch Valve
High-reliability fluidic component designed for safe and autonomous isolation or venting of spacecraft propulsion systems. Its compact, robust design ensures leak-tight sealing without continuous power, offering a lightweight, plug-and-play solution for pressure vessel isolation at launch or end of life.
Discover more >High-performance, simple and cost-effective water-based resistojet propulsion system. Standing out as best-in-class on thrust and specific impulse in its category. Designed for high modularity allowing various tank sizes, thrust levels and total impulse making it the ideal solution for various deorbiting and mission manoeuvers.
ASCEND Propulsion System
Low size and high responsivity cold-gas based reaction control system. Featuring four independently controllable thrusters, a single unit enables precise maneuvering of the spacecraft within four degrees of freedom while two units expands control to six degrees of freedom. Agile, compact and modular, it is ideally suited for tasks such as rapid collision avoidance maneuvers in Earth orbit and attitude control in lunar orbit and deep space.
