Stellar Alpina is a Zurich-based space venture developing high-performance Rotating Detonation Engines, modular in-space vehicles and lunar delivery systems. Our mission is to build upstream hardware that gives Europe a sovereign path to the Moon. Founded by ARIS Alumni, we combine hands-on engine development, system design expertise and shared leadership to create a scalable architecture for propulsion and lunar access. Our work is grounded in Swiss precision and driven by the belief that world-class space systems can be built in Zurich. Stellar Alpina is shaping the next chapter of European space infrastructure: engines, vehicles and landers built to deliver reliably to the lunar surface.
