The APU (auxiliary proportion unit) allows the engine to be reactivated. It re-pressurizes the tanks so that they can be ignited. APU ensures a stable thrust in the fuel flow.

If the Vinci engine and the APU (auxiliary proportion unit) can't be reactivated the planned orbit for the return to Earth can't be reached. This is also a issue because of leaving space debris.

The restart of the Vinci engine has happened but short after the restart the engine shutdown automatically as a safety measurement. This results that Ariane 6 is not in the planned orbit attitude any more.

We are waiting for the Go of the launch. All systems look good at this moment.
Mission control room is about 20 kilometres away from the launch pad.

When the rocket is installed the mobile gantry will roll away making space for Ariane 6 to launch.
The Ariane program is a program financed by Europeans for Europeans.

This reduces transport costs by 50% and the engines of the ship are be able to reduce emissions by 30 %. Kourou, the locations of the launch pad in French Guiana is near the equator. As soon as all parts are arrived they will be installed.
#Ariane6 #ESA #FrenchGuianca #Ariane #VA262 #GoAriane
The different parts of the rocket are produced allover Europe and the installed stages are then shipped to French Guiana. A special designed ship makes monthly round trips between South America and Europe.
