Helios is a high-performance orbital transfer vehicle designed to move large payloads from low Earth orbit to high-energy destinations with unprecedented speed and efficiency. When paired with a medium-lift launch vehicle, Helios enables same-day delivery to geostationary orbit, dramatically reducing mission timelines and operational complexity.
By minimizing time spent in intermediate orbits, Helios lowers overall mission cost while unlocking months of additional on-orbit operations for commercial, civil, and defense payloads. Its vertically integrated manufacturing approach ensures predictable schedules, controlled costs, and rapid mission readiness — Helios is flight-ready when your payload is.
With up to 9 km/s of delta-v, Helios supports a wide range of mission profiles, from GEO primary or secondary payload insertion to MEO constellation deployment, cislunar missions, and deep-space trajectories. High-energy orbital delivery is no longer a niche capability — with Helios, it becomes a practical and accessible solution for the next era of space mobility.
