Building Europe’s Next-Generation Reusable, Very Heavy-Lift Launcher
Making Space a Catalyst for Earth’s Global Decarbonization
Our Purpose
We exist to build a future where space directly serves Earth, powering clean energy, securing data, and a carbon-free economy.
​
Our company positions itself as the lead designer of Europe’s next-generation very heavy launchers.
Hstar Space is a French aerospace company developing a large-scale, reusable launch vehicle through an innovative hybrid economic model inspired by industry leaders best practices, to combine technical excellence, industrial resilience, and market adaptability.
​
Our ambition is to make Europe the global leader in sustainable and intelligent launch systems by building the most inspiring space ecosystem for future generations — where every euro invested drives both Earth’s decarbonization and the responsible expansion of humanity into space.



To pioneer the development of a European very-heavy, fully reusable space transportation system, leading system integration while orchestrating a horizontal European supply chain that leverages both industrial champions and NewSpace innovators for large-scale production and sustainable deployment. Leveraging a user-centric co-design approach, we tap into vertical markets like energy and data to secure demand and drive long term profitability.
