United Launch Alliance Vulcan rocket launched as part of Cert-2 mission

United Launch Alliance (ULA) took a critical step in the certification process with the successful launch of the Vulcan VC2S rocket from Space Launch Complex 41 at Cape Canaveral Space Force Station, Florida. The launch, which took place after several hours of delay, is part of the second certification mission (Cert-2) needed by the US Space Force to ensure reliable access to space.

Led by carrier pilot Dillon Rice. the ground crew completed final preparations before authorizing the start of cryogenic loading. More than 450,000 kilograms of cryogenic fuel were successfully loaded into the rocket for launch. The mission included an inert payload and a series of technology demonstrations related to the Centaur V upper stage, which is key to the development of future space missions.

The Vulcan took off with the help of methane-powered main engines and two solid rocket boosters manufactured by Northrop Grumman. After ignition, the rocket followed an east-southeast direction to reach an initial parking orbit and then continue on an interplanetary trajectory into deep space. Two minutes and 14 seconds after takeoff, the solid fuel boosters successfully separated, leaving the BE-4 main engines to continue accelerating.

Throughout the flight, The Centaur V upper stage, powered by two RL10C-1-1A engines, performed several critical maneuvers to place the payload on the planned trajectory. These engines, part of a family with more than 60 years of history, are known for their fundamental role in launching satellites and interplanetary missions into orbit.

The Cert-2 mission is key to the final validation of Vulcan as a launch vehicle. which will strengthen ULA’s ability to provide reliable access to space for military, government and commercial applications.
