ESA and Arianespace i aiming at january as launch-date for the first Vega-rocket. The small rocket is intended to carry small cargoes into space at a competitable price.

Although there is a growing tendency for satellites to become larger, there is still a need for a small launcher to place 300 to 2000 kg satellites, economically, into the polar and low-Earth orbits used for many scientific and Earth observation missions.

Europe’s answer to these needs is Vega, named after the second brightest star in the northern hemisphere. Vega will make access to space easier, quicker and cheaper.

Costs are being kept to a minimum by using advanced low-cost technologies and by introducing an optimised synergy with existing production facilities used for Ariane launchers.

Vega has been designed as a single body launcher with three solid propulsion stages and an additional liquid propulsion upper module used for attitude and orbit control, and satellite release. Unlike most small launchers, Vega will be able to place multiple payloads into orbit.

The first Vega launch campaign began on Monday at Europe’s Spaceport in French Guiana with the installation of the first stage on the pad. Europe’s new small launcher is on track for its maiden flight at the end of January.

The hundred-tonne solid-propellant first stage, the P80, was moved from the Booster Integration Building to the pad on 7 November using the ‘Fardier’ heavyweight transporter. As with the transfer of Ariane 5’s boosters, safety measures minimised the number of operators on site and evacuated nearby buildings.  

With the P80 installed inside the mobile gantry, all ground installations are now being configured for the booster’s final acceptance, including the Thrust Vector Control system that swivels the large nozzle for steering.

In the coming weeks, the two solid-propellant second and third stages, the Zefiro-23 and Zefiro-9, will be transferred from the Vega Booster Storage and Preparation Building and added to the vehicle. Before the end of the year, after the Flight Readiness Review, the AVUM – Attitude & Vernier Upper Module – fourth stage, will be integrated.

Final preparations for launch
In parallel to the launcher activities, the satellites are being prepared at the spaceport.

By the end of the year the LARES laser relativity satellite from Italy’s ASI space agency together with at least six small CubeSats and ALMASat-1 from European universities will be ready and enclosed in the fairing.

The campaign will continue in January with the integration of the ‘upper composite’ – the fairing and payload – followed by final check-out of the fully integrated launcher and the countdown rehearsal.

This Vega qualification flight will pave the way for the next five missions that will demonstrate the system’s flexibility as part of the VERTA – Vega Research and Technology Accompaniment – programme.

A flexible system
Vega is designed to cope with a wide range of missions and payload configurations in order to respond to different market opportunities with greater flexibility.

In particular, it offers configurations able to handle payloads ranging from a single satellite up to one main satellite plus six microsatellites.

Vega is compatible with payload masses ranging from 300 kg to 2500 kg, depending on the type and altitude of the orbit required by the customers. The benchmark is for 1500 kg into a 700 km-altitude polar orbit.
