Live coverage: Ariane 5 successful in middle-of-the-night launch

Europe’s top rocket contractor is pressing ahead with development of the Ariane 6 rocket, a versatile launcher with half the cost of Europe’s current Ariane 5 booster, keeping the new vehicle on track for its 2020 debut.

Giulio Ranzo is the chief executive of Avio, the Italian company responsible for building the Vega rocket. Ranzo recently spoke with Spaceflight Now about the Vega rocket’s increasing launch rate, the debut of the new Vega C booster in 2020, and future plans to evolve the Vega design to compete with commercial microsatellite launchers.

Launch crews in French Guiana have mounted an innovative European space plane on top of a solid-fueled Vega launcher for a Feb. 11 suborbital test flight.
