Ariane 6 hot-fires: the highlights

Video: 00:01:25

Cinq, quatre, trois, deux, un. Allumage Vulcain! This is the moment Ariane 6’s main engine was sparked into life, and the entire main stage of the new rocket and the many parts of the launch pad in Kourou, French Guiana, practised for the full duration of a launch. Of course, as planned, the test model did not leave the ground.

Without its boosters, instead of piercing the clouds Ariane 6’ created its own on Earth: a clean byproduct of the Vulcain 2.1 engine’s oxygen and hydrogen propellants, which came together to send out impressive swirls of H2O.

After the almost 150 tonnes of propellant was burnt through and the clouds dispersed, the curtains closed on the successful rehearsal. The data from thousands of monitors around the rocket will be crunched in the coming weeks to learn all that’s needed for Ariane’s next, real, flight.
