The successful qualification flight of the VSB-30 occurred in October 23, 2004, in Alcantara, Brasil, after a long campaign mainly due to adverse wind conditions. In the wake of this flight, lies the renewed hope to keep the European sounding rocket microgravity program alive. This paper presents technical aspects of the main subsystems, the rocket and flight results. In the subsystem level, the results of the three firing tests of the S31 motor are presented together with the expected flight trust curve. The second stage fins and the payload service module were also important develoments that required extensive ground test qualification. The use of the ground qualified thrusters for the VLS-1 spin-up system proved to be a good asset for the VSB-30 spin up system. The second stage tail can and the payload adapter have large structural margins and did not undergo qualification tests. In the system level, the main tasks were to predict the trajectory parameters and establish the flight safety procedure. The payload service module was equipped with 3-axis gyros, accelerometers, vibration accelerometers, a GPS receiver and temperature sensors that provided a wealth of information on the flight dynamics, trajectory parameters and the mechanical environment. All expected and unexpected results are discussed.
