Watch Ariane 5 launch with Star One D1 and JCSAT 15

Five European satellites, including a Italian radar surveillance craft and an ESA exoplanet probe, lifted off Wednesday at 0854 GMT (3:54 a.m. EST) from French Guiana aboard a Russian Soyuz rocket. A launch attempt Tuesday was scrubbed due to a software concern with the launch vehicle.

A Soyuz rocket took off from French Guiana on Thursday with the SES 15 communications satellite, a craft heading for an orbit more than 22,000 miles over the equator to provide airborne wifi and aeronautical navigation services over the United States.

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.
