The groundbreaking Vulcan Centaur, the latest addition to the United Launch Alliance (ULA) family of rockets, is on the brink of its maiden voyage, the culmination of years of design, manufacturing, and rigorous testing. This magnificent craft, standing tall at a majestic 202 feet, is set to define the future of space exploration.

As the sun set over the Cape Canaveral Space Force Station in Florida on June 7, the Vulcan Centaur achieved a pivotal milestone, successfully executing a critical engine test - the first of its kind for this pioneering machine.

In the world of rocketry, countdowns are moments filled with anticipation and nail-biting suspense. The magic started at T-4.88 seconds, the engine start sequence initiated, as Vulcan Centaur's two main-stage engines roared to life on the launch pad. What followed was a burst of power lasting two seconds, where the engines reached their intended thrust level, and then gradually wound down. This crucial Flight Readiness Firing (FRF) test, as brief as it was significant, encompassed a span of just six seconds.

Powering the Vulcan Centaur's inaugural stage are two BE-4 engines, the brainchild of Blue Origin, while the Centaur V upper stage is propelled by a pair of RL-10 engines. The versatility of this spacecraft does not stop there. The design also allows for the addition of up to six strap-on solid rocket boosters, augmenting its launch capabilities further.
