VEGA – VEGA C PROGRAM
The VEGA project is a launch system (launch vehicle & launch base) for payloads up to 1500 kg at 700 km in SSO polar orbit. The small Vega launcher, developed by AVIO SpA, 30 meters high with a maximum diameter of 3 meters and weighing 137 tons, consists of three solid propellant stages (P80, Zefiro 23, Zefiro 9), a liquid propulsion high stage with multiple re-ignition capability (Attitude and Vernier Upper Module – AVUM) and an Upper Composite which contains one or more satellites.
The VEGA C project is the upgraded version of the VEGA launcher for payloads up to 2300 kg in low Earth orbit. The new launcher, 35 meters high with a maximum diameter of 3.3 meters and a weight of 210 tons, consists of three solid propellant stages (P120, Zefito 40, Zefiro 9), a liquid propulsion high stage with multiple re-ignition capability (AVUM) and an Upper Composite which contains one or more satellites.
Both launchers are integrated and launched from the VEGA Launch Base (ZLV) located in the European Space Center in French Guiana.
