The Matterhorn project was the association’s first major project, and what a start! After only one year of development, the team managed to win the prestigious “Jim Furfaro Award for Technical Excellence” given to the team that best demonstrated the mastery of the rocket’s integrated technologies.




Epoxy impregnated fiber glass nose cone. Unlike the carbon fiber body, radio waves can penetrate this composite material, making it a great choice for housing part of our avionic and antennas.

Experimental Payload

Student researched and developed muon detector. Thanks to its 8 muon sensible scintillating plastic rods, the detector can estimate its descent speed based upon the muon detection rate. The payload has its own parachute which deploys completely at ejection and GPS beacon to aid recovery when it hits the ground. Thanks to its accelerometer, the payload can detect when liftoff occurs thus turning itself on. This minimizes battery usage.


In-house developed controllers for parachutes and airbrakes in the center while telemetry and localization sensors are in the nose cone.


We call them the « shuriken airbrakes ». Our rocket’s engine is planned to overshoot by around 500 meters. Taking account the wind, air pressure and other parameters, the on-board computer controls the airbrakes. A space-grade Faulhaber actuator drives a gearwheel which then drives the three breaking surfaces.

Ground Segment

From the ground, we receive heaps of data from the rocket’s on-board computer. Functionalities of the station include discrete event identification, flight prediction visualisation and altitude check.

Recovery Bay

Most critical sub-system of the rocket, our recovery system functions with a single parachute. To minimize drifting due to high-altitude winds, the parachute’s shape is modified during the recovery using a technique called reefing. This is managed by changing the length of the central cord. The parachute’s ejection is done by piercing two CO2 capsules at apogee, thus creating an over pressurization. The payload comes out first and is attached to the parachute bag. As the chute bag is being pulled by the payload, the parachute comes out of the rocket and deploys itself, initially reefed.

Structure and Fins module

Made from epoxy impregnated carbon fiber, the multiple rocket tubes are assembled using a SRAD coupling system capable of lifting a small car! An easily removable fin module allows us to quickly swap them with 3mm thick carbon fins in case of damage.


It is using a solid COTS (Commercial Of-The-Shelf) rocket engine.
