Aventura I — Small Launch Vehicle

Aventura I is an ultralight launch vehicle optimized for deploying nanosatellites into Low Earth Orbit. Designed with a focus on simplicity, rapid turnaround, and cost-efficiency, it enables frequent access to space for new markets.

Published vehicle characteristics include 10 m height, 0.352 m diameter, two stages, about 20 kg payload, nominal 500 km LEO, 14 kN atmospheric engine at lift-off, 1.0 kN vacuum engine, ECOSTAR ATM electropump-driven propulsion, HTP plus proprietary NHMF propellants, storable non-cryogenic storage, hypergolic ignition, and a carbon-fiber composite fuselage.

ECOSTAR combines high-test peroxide with Tlön’s NHMF fuel. The system is hypergolic, electropump-driven and designed to simplify ground operations without relying on cryogenic or hydrazine-class propellants.
