Vega (Vettore Europeo di Generazione Avanzata, European Advanced Generation Vector) is a planned expendable launch system developed jointly by the Italian Space Agency and the European Space Agency since 1998, with the first launch planned for 2008. It is designed to launch small payloads: 300 to 2000 kg satellites for scientific and Earth observation missions to polar and low earth orbits. It is named after the star Vega. It is a single body launcher with three solid rocket stages, the P80 first stage, the Zefiro23 second stage, the Zefiro9 third stage, and a liquid rocket upper module called AVUM. The technology developed for the P80 program shall also be used for future Ariane developments. Italy is the leading contributor to the Vega program with 65%, other participants being France (12.43%), Belgium (5.63%), Spain (5%), The Netherlands (3.5%), Switzerland (1.34%) and Sweden (0.8%). The reference VEGA mission is a polar orbit bringing a spacecraft of 1,500 kilograms to an altitude of 700 kilometers.

First engine test

The first full-scale test of the Vega engine took place on 4 December 2007 in Kourou. [1]

Future developments

The future upgraded Vega (LYRA program) has exceeded the feasibility study and is planned to have new third and fourth low cost LOX/HC stages and a new guidance system. The purpose of the program is to upgrade the polar orbit payloads to up 2,000 Kg.
