Development began in 1998 and the first launch took place from the Guiana Space Centre on 13 February 2012. Arianespace has ordered launchers covering the period till at least the end of 2018.〔 It is designed to launch small payloads — 300 to 2,500 kg satellites for scientific and Earth observation missions to polar and low Earth orbits. The reference Vega mission is a polar orbit bringing a spacecraft of 1,500 kilograms to an altitude of 700 kilometers. Vega, named after the brightest star in the constellation Lyra, is a single-body launcher (no strap-on boosters) with three solid rocket stages: the P80 first stage, the Zefiro 23 second stage, and the Zefiro 9 third stage. The upper module is a liquid rocket called AVUM. The technology developed for the P80 program will also be used for future Ariane developments. Italy is the leading contributor to the Vega program (65%), followed by France (13%). Other participants include Spain, Belgium, the Netherlands, Switzerland and Sweden. ==Payload capacity== Arianespace indicates a Vega launcher is able to carry to a circular polar orbit at an altitude of .〔(【引用サイトリンク】title=Vega — Overview )〕 Arianespace is marketing Vega as a launch system tailored for missions to polar and sun-synchronous orbits.〔(【引用サイトリンク】title=Vega — Performance )〕 In its qualification flight VEGA put its main payload of 386.8 kg, the LARES satellite, into a circular orbit at the altitude of 1450 km with an inclination of 69.5 degrees.〔I.
