Problem
Conventional space propulsion systems rely on chemical combustion and limited impulse performance, constraining payload capacity and mission flexibility for deep-space travel. The growing demand for lunar and interplanetary missions requires more efficient propulsion approaches that can reduce transit times and enable heavier cargo deliveries between Earth and the Moon.
Solution
Stellar Alpina is developing propulsion technology based on detonation physics to improve efficiency and thrust performance for space mobility. The company's approach leverages detonation-based combustion cycles, which can extract more energy from propellants than traditional deflagration systems. This technology is intended to power spacecraft and transfer vehicles operating between Earth and lunar orbits, supporting cargo and potentially crewed missions. Stellar Alpina is building its engineering capabilities and partner network to mature the technology from concept toward flight-ready systems.
Target Audience
Primary customers are space agencies, satellite operators, and commercial lunar logistics providers requiring efficient propulsion systems for Earth-Moon transportation and deep-space missions.
