On March 8, 2023, Tlon Space flew the first stage of its Aventura I rocket.

The purpose of the flight was to test all the subsystems of the vehicle, such as the structural fuselage made all in composite materials, the ECOSTAR E1 rocket engine, which is fueled by electric pumps, the avionics as guidance, navigation, control, data&video downlink, and flight termination uplink.

This test was carried out after important works to complete the infrastructure of Tlon’s spaceport, which included improvement in access to launch Pad and control areas, in the ground network and electricity supply, an establishment of security protocols, among others.
