Tlön Space — Enabling your access to Space

Tlön develops ultralight launch vehicles to deploy nanosatellites into low Earth orbit, reducing costs and democratizing access to space from Argentina. Our vision is to create the most frequent and cost-effective Small Launch Vehicle in the world to serve the Smallsat Industry.

Aventura I

Aventura I is an ultralight, two-stage launch vehicle optimized for dedicated nanosatellite missions into Low Earth Orbit. It is about 10 m tall, 0.352 m in diameter, and designed for roughly 20 kg to a nominal 500 km LEO. ECOSTAR propulsion is electropump-driven, hypergolic and non-cryogenic, using high-test peroxide and Tlön’s proprietary NHMF fuel blend in a carbon-fiber composite structure.

Malacara Spaceport

Malacara Spaceport in Lobería, Buenos Aires is Tlön’s operational launch site for dedicated nanosatellite missions, flight-test campaigns and launch operations.

Heritage

Tlön is a Certified B Corporation, with 200+ engine test firings, 9 test flights across Aventura 0 and Aventura I, and core subsystems validated including ECOSTAR, GNC, DLink, FTS, composite structure and TLM.
