The COSMOS Student Aerospace Association successfully launched the SATUS-1 rocket, its first vehicle developed entirely as part of its experimental rocketry training program.
The event took place last Saturday April 5 at 13:28 p.m., in the Brunete Aerodrome, under optimal weather conditions. This launch marks the beginning of a new era for COSMOS and for the practical training in aerospace engineering provided at the Fuenlabrada School of Engineering la URJC.
Technical validation and real learning
During flight, SATUS-1 reached a altitude of 450 meters, below the 980 meters planned, due to a minor engine combustion mishap. However, the mission was a Resounding success: enabled the validation of multiple key systems, demonstrated effective vehicle integration, and laid the groundwork for even more ambitious future developments.
The rocket, from Meters 1,21 y 7,9 centimeters in diameter, is powered by a solid fuel engine with a mixture based on ammonium perchlorateSATUS-1 was conceived as a learning platform, integrating structural design, electronic systems, telecommunications, operation, and safety under high-performance standards.
a team work

This project would not have been possible without the exemplary leadership of its three technical directors:
- Enrique Torres Hernández, project director and general coordinator of the launch.
- Joaquín Vispe Fondevila, co-director of the project, responsible for the structural design of the vehicle.
- Patrick Townsend Falcones, project co-director, responsible for electronic and telecommunications systems.
Along with them, he has worked a the entire rocketry team, comprised of passionate students who have dedicated their talent, time and energy to the development, testing and execution of the mission.
The team members are especially grateful to all the people and institutions that have accompanied them on this journey:
- Pablo Solano, professor of Aerospace Engineering, for his technical and academic support.
- Angel Raúl Zepeda Vargas, member of the Astro Exploration Rocketry Team of the Autonomous University of Baja California, for their international collaboration during the first four months, contributing experience and knowledge in propulsion systems. Their support has been key to making this launch a reality.
Pnext challenge: Towards EuRoC

Following the launch of SATUS-1, the COSMOS rocketry team is now preparing to compete in the prestigious European Rocketry Challenge (EuRoC), with the development of Lightning Traveler, a new rocket designed to reach the 3.000 meters.
This milestone places COSMOS as a partnership with international projection, committed to excellence, technological innovation and applied learning in the space field.
