The Small Spacecraft Mission Service (SSMS) dispenser will allow dedicated rideshares to space. Routine dedicated rideshares to space for small satellites. Vega-C’s range of adapters make this a very flexible launch vehicle. Vega-C mission capabilities Vega-C for a wide range of missions During its two-minute burn this motor delivers an average thrust of 4,500 kN – equivalent to the output of 15 modern airliner engines.Īnd, the P120C will do double service, with either two or four of these solid fuel motors acting as strap-on boosters for ESA’s Ariane 6 launch vehicle. P120C’s monolithic carbon fibre structure weighs about 8 t and carries 143.6 t of solid propellant. Vega-C's P120C first stage replaces Vega’s smaller P80 to provide a significant increase in thrust at liftoff. The new Zefiro-40 second stage contains 36.2 t of solid propellant, providing an average thrust of 1304 kN. The third stage, Zefiro-9, is taken from Vega and burns 10 t of solid propellant.
After separation of all payloads, a final boost may deorbit the upper stage to minimise debris left in orbit. Thrusters may burn several times to reach all required orbits. AVUM+ has a propellant mass of 740 kg and the main engine will provide an average thrust of 2.42 kN. The reignition capability of the AVUM+ allows Vega-C to reach a range of orbits to deliver multiple payloads on a single mission. The upper stage AVUM+, or Attitude Vernier Upper Module, ensures attitude control and precise orbital positioning and is designed for extended stays in space. Made of carbon fibre-polymer composite, this structure protects satellites from the thermal, acoustic, and aerodynamic stresses of liftoff and on the ascent through Earth's atmosphere. The ogive-shaped fairing at the top of Vega-C is 3.3 m in diameter and over 9 m tall, doubling the payload volume available with Vega. As with Vega, its main elements are three solid propellant stages, an upper fourth stage powered by a reignitable liquid-propellant engine and a payload fairing. Vega-C is based on the Vega launch vehicle.
