Ariane 6 revealed on its launch pad in preparation for hot-firing tests

Paris, France (SPX) Jun 23, 2023

As part of the combined tests campaign, the Ariane 6 mobile gantry was retracted on June 22, unveiling the launch vehicle on its launch pad. During a rehearsal representative of a real launch sequence, the removal of the mobile gantry marks the completion of the functional tests performed so far and precedes ignition of the core stage Vulcain 2.1 engine on the launch pad. The rehearsal serves to run through the engine ignition test, to minimize the risk of any problems during the final sequence.

For several months, teams from ArianeGroup, CNES and ESA have been working together to conduct combined tests at the Spaceport in Kourou to verify and qualify the interfaces between the launcher and its launch pad. Following the launch sequence chronology, various rehearsals are carried out to qualify, step by step, the different functions and operations leading up to lift-off.

Before the mobile gantry was removed, the teams carried out functional and avionics systems tests known as "dry runs", during which all the launch vehicle's avionics chains were armed to achieve a stable, repeatable configuration leading to the final synchronized sequence and handover to the flight program for Vulcain 2.1 engine ignition.

Final launch of Europe's Ariane 5 rocket postponed
Paris (AFP) June 15, 2023
The final launch of Europe's Ariane 5 rocket has been postponed due to a technical problem, French firm Arianespace said on Thursday, in the latest blow to European space efforts. After 27 years of launches, the Ariane 5's 117th and last mission had been scheduled to blast off between 2126-1001 GMT on Friday from Europe's spaceport in Kourou, French Guiana. But "it has come to light that there is a risk to the redundancy of a critical function on the Ariane 5," tweeted Arianespace, which operate ... read more
