A European Ariane 5 rocket fired into a gloomy sky Thursday over French Guiana and streaked into space from the tropical launch base with 2.9 million pounds of thrust from two solid rocket boosters and a hydrogen-fueled Vulcain 2 main engine.

The first of up to 22 launches on Arianespace’s schedule in 2020 successfully delivered a commercial European broadband satellite and an Indian communications payload to orbit Thursday using a heavy-lift Ariane 5 rocket.

A nearly 180-foot-tall (54.8-meter) Ariane 5 rocket rolled out of its integration hangar to the ELA-3 launch zone Wednesday at the Guiana Space Center in South America, moving into position for liftoff Thursday with two geostationary communications satellites.

A broadband communications satellite for Paris-based Eutelsat — built on a new Thales Alenia Space all-electric design with xenon plasma thrusters — and an Indian broadcasting spacecraft are fastened to the top of an Ariane 5 launcher for liftoff Thursday from French Guiana.
