First Vega launch campaign
The first Vega launch campaign began on 7 November 2011 at Europe’s Spaceport in French Guiana with the installation of the P80 first stage on the pad.
The two solid-propellant second and third stages, the Zefiro-23 and Zefiro-9, were then transferred from the Vega Booster Storage and Preparation Building and added to the vehicle.
All three stages underwent final acceptance, including testing of their thrust vector control system. The next step was to move the AVUM – Attitude & Vernier Upper Module – liquid-propellant fourth stage to the pad for mating.
The ‘upper composite’ – the fairing and payload – was moved to the pad and integrated on 24 January 2012.
It was followed by final checkout of the fully assembled launcher and the countdown rehearsal.
