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.
