Preventive solutions to space debris

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.

Live Interview on BFM Business

Ascend Beyond Space was recently featured on Tech & Co on BFM Business to showcase our ecosystem of solutions aimed at preventing space debris and contributing to a more sustainable future in space. Our flagship product is a revolutionary, eco-friendly propulsion system that uses water as fuel and fully disintegrates at the end of its mission. This minimizes environmental impact and ensures a cleaner orbital environment for future generations. Designed and manufactured entirely in France, our systems leverage the advanced industrial expertise of our local partners in the Haute-Savoie region. Together, we are working to strengthen France’s space sovereignty for the long term. 🎙 You can (re)watch the full interview here: https://www.bfmtv.com/economie/replay-emissions/tech-and-co/quentin-mannes-ascend-beyond-space-une-solution-pour-reduire-les-debris-spatiaux-10-03_VN-202503100860.html

Orbiting at Tech & Fest Grenoble

Ascend Beyond Space wrapped up an incredible two days at TECH&FEST Grenoble, where we proudly unveiled the Ascend Propulsion System for the first time! Designed to make sustainable mission termination accessible to all, the system received an enthusiastic response from both industry professionals and newcomers eager to tackle the growing challenge of space debris. The event was packed with insightful discussions, from engaging with local suppliers and industry leaders to connecting with passionate space advocates. A key highlight was the visit of Geneviève Fioraso, former Minister for Higher Education and Research, whose commitment to promoting space awareness strongly aligns with our mission. This is just the beginning of our journey toward a more sustainable future in space!
