Ariane 6 pre-show wet dress rehearsal finished
The excitement was palpable as teams from ESA, CNES, and ArianeGroup meticulously prepared for the wet dress rehearsal of Ariane 6 flight model-1. Months of meticulous planning had led to this pivotal moment, where every step would be executed with unwavering precision.
The first task was to roll back the colossal 90-meter-tall Ariane 6 mobile gantry building, unveiling the majestic rocket standing tall on the launch pad. This marked the first time the complete rocket stood free, a sight that filled onlookers with a sense of awe and anticipation.
Next, the intricate process of fueling the rocket began. Over the course of 3.5 hours, technicians at the control center skillfully cooled the pipes, valves, tanks, and engines from the tropical temperatures of French Guiana, around 30 degrees Celsius, down to the super-chilled temperatures required for the cryogenic propellants:
- Liquid oxygen at a frigid -180°C
- Liquid hydrogen fuel at an astonishing -230°C
Meticulous care was taken to ensure no humidity remained in the system, as any moisture would immediately freeze and potentially block valves at such extreme temperatures. Inert nitrogen gas was used to flush out any traces of air or humidity before fueling commenced.
As the tanks steadily filled, teams remained vigilant, continuously topping them up to compensate for the inevitable boil-off of the supercooled propellants under the relentless tropical sun. Once the tanks were full, the rocket stood ready, a towering symbol of human ingenuity and the culmination of years of dedication.
