There still is a need for a small launcher capacity to place 300 to 2000 kg satellites into the polar and low-Earth orbits used for many scientific and earth observation missions. Europe is developping Vega, named after the second brightest star in the northern hemisphere. Vega will make access to space better. 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.

Dutch Space is responsible for the development of the Vega Interstage 1/2. This all-aluminium conical Interstage is designed as a monocoque structure using 2mm thick plates without stringers. The Interstage has a front and aft part to be separated during launch. Dutch Space will therefore also be responsible for the installation of the separation line (pyro cord) and retro-rockets for firing away of the first stage together with the aft interstage at moment of separation.
VEGA Interstage 1/2 Qualification Models in different stages of assembly
The qualification of the Interstage 1/2 has been succesfully completed. Delivery of the first Flight Model will be summer of 2010. Maiden flight of VEGA is scheduled for beginning 2011.
