ULA’s Vulcan Rocket Completes Critical Second Test Flight, Despite Booster Anomaly

United Launch Alliance (ULA) successfully launched its second Vulcan Centaur rocket on October 4, 2024, marking a major step toward certifying the rocket for future national security missions. Despite a minor booster anomaly detected shortly after liftoff, the mission proceeded as planned, achieving key objectives.

On October 4, 2024, United Launch Alliance (ULA) successfully launched its second Vulcan Centaur rocket, marking a key step toward certifying the rocket for national security missions. However, at 37 seconds after liftoff, one of the rocket’s solid-propellant strap-on boosters suffered an anomaly, ejecting sparks and debris. Despite the issue, the rocket maintained its trajectory, and the mission proceeded as planned. ULA has announced an investigation into the anomaly to assess its impact on the certification process.

The Mission Objectives and Its Significance

This launch, called CERT-2, is the second of two certification test flights that are necessary before Vulcan can begin carrying high-priority national security payloads for the U.S. Space Force and the National Reconnaissance Office (NRO). These payloads often include critical technologies, such as optical and radar imaging, encrypted communications, and electronic eavesdropping satellites. The rocket did not carry an active payload for this flight; instead, ULA used a dummy payload to simulate mass and added technology demonstration experiments to gather data about the rocket’s performance.

Vulcan Centaur’s upper stage, the Centaur 5, played a key role in demonstrating the rocket’s ability to restart its engines in space, a crucial requirement for military payloads that need to reach complex, high-energy orbits. The Aerojet Rocketdyne RL10C engines fired twice during the flight to achieve this milestone. The mission lasted approximately 54 minutes, and the extra data gathered from onboard instruments will help engineers further characterize the vehicle's performance.

Vulcan’s Future and Certification Challenges

Despite the booster anomaly, the flight’s success moves ULA closer to certifying Vulcan Centaur for national security missions. However, it remains unclear how this anomaly will impact the certification process. Tory Bruno emphasized that while the strap-on booster issue was not severe enough to affect the overall flight, it will need to be thoroughly investigated to ensure the rocket’s reliability for future missions. The investigation could delay final certification, but ULA plans to move forward with more missions later this year.

Vulcan Centaur represents the future of ULA’s launch capabilities, replacing the aging Atlas V and Delta IV rockets. The rocket is designed to be more cost-effective, with a launch cost under $100 million, making it competitive with SpaceX’s Falcon 9 and Falcon Heavy rockets. However, unlike SpaceX’s reusable rockets, Vulcan Centaur is fully expendable. This presents some challenges in terms of pricing, as SpaceX’s reusability allows it to offer lower-cost launches. Nonetheless, Vulcan’s ability to carry heavier payloads to high-energy orbits gives it a competitive edge for certain missions.

ULA still has 15 Atlas V rockets in its inventory, which will be used for upcoming launches, including Amazon’s Kuiper internet satellites and NASA’s Starliner crewed missions to the International Space Station. Once the Atlas rockets are retired, Vulcan Centaur will be ULA’s sole launch vehicle for commercial and government missions.

Looking Ahead: National Security and Beyond

The next steps for Vulcan Centaur include two national security missions planned for later this year, which will likely carry sensitive payloads for the U.S. Space Force or NRO. These missions are seen as urgent by ULA, further increasing the pressure to resolve the booster issue and complete certification. While no specific payloads have been announced, national security launches often involve highly classified technology aimed at supporting U.S. defense and intelligence capabilities.

As Vulcan Centaur continues its development, ULA aims to position the rocket as a leading vehicle in the competitive space industry. Tory Bruno remains confident that despite the challenges, Vulcan will provide a reliable and capable platform for future launches, ensuring ULA’s continued presence in the launch market.

CERT-2 represents a significant step forward for ULA, but the road to full certification and operational status for national security missions remains complex. The booster anomaly will need to be thoroughly examined, and the results of the investigation could shape the timeline for Vulcan’s future missions. However, with multiple missions planned and a growing demand for national security launches, ULA is well-positioned to meet the challenges ahead.
