Hstar

Hstar is building the transportation systems that will make space not just reachable, but livable, navigable, and valuable. We are a cooperation of mission-aligned companies developing the infrastructure layer for a scalable human presence in orbit. From fully reusable heavy-class launchers to in-space shuttles and safety systems, our focus is clear: enabling safe, routine access and movement in space, while always staying connected to Earth. Each Hstar entity is rooted in a specific region, but contributes to a shared global mission. • Hstar Space is designing Europe’s next-generation heavy-lift vehicle. • Hstar Orbital is delivering in-space mobility and satellite coordination systems, including Pulsar, our space-based GNSS transponder. • Additional operations across the U.S., France, Australia, Japan, and beyond are advancing key capabilities—from reentry and refueling to logistics, AI flight systems, and ground operations. Together, we’re building the systems that will support the next era of space activity - commercial stations, research platforms, constellations, and the lives and cargo they carry.
