On Thursday the 30.08.2012 at 11:04 CET, the second experimental rocket of the TU Wien Space team launched in Biscarrosse, France. As planned, the rocket separated at apogee releasing the small and later the main parachute. After a soft landing 1.2 km from the launch site “STR-02 Hornet” finished its maiden voyage “VOL NOMINAL” and sent it’s GPS Coordinates via RF Telemetry to the control station.

STR-02 Hornet was designed and built in a time frame of 12 months by 8 students with the help of many sponsors and various institutes of the TU Wien.
