VEGA: launcher

VEGA LAUNCHER MAIN CHARACTERISTIC

Vega is the ESA’s satellite launch vehicle designed to send small satellites into Low Earth Orbit (LEO). It provides great flexibility of mission at an affordable cost. Together with the Ariane launcher family, it represents the European solution for space accessibility.
Vega can carry up to multiple payloads at a time in any orbit up to 1,500 km (reference performance is 1,500 kg at a circular polar orbit of 700 km).
Vega is a four stage vehicle powered primarily through solid propulsion. It is 30m high and weights 137 tons at lift-off. It hosts a payload dynamic envelope of 2.3 m diameter and 6.3 m height.
