Mississippi, USA — Ekhbary News Agency
Rocket Lab announced the successful completion of a pivotal qualification test for its Archimedes engine, a critical component poised to power the company's next-generation Neutron launch vehicle. This full-duration burn, executed at NASA’s Stennis Space Center in Mississippi, signifies a major leap towards Neutron's inaugural flight, anticipated later this year.
Key Milestone Achieved for Neutron
The recent test involved a second-stage Archimedes engine, firing for just under 5.5 minutes to simulate flight conditions. Company officials lauded the achievement on social media, describing it as a "thing of beauty" and "critical preparation." This rigorous evaluation paves the way for integrating the engine with the Neutron rocket in the coming months. For what it's worth, such meticulous testing underscores Rocket Lab's commitment to reliability.

Neutron's Innovative Design and Reusability
Neutron distinguishes itself with a unique design, featuring eight Archimedes engines on its first stage, collectively generating nearly 1.5 million pounds of thrust at liftoff. Like SpaceX's Falcon 9, Neutron's first stage is engineered for partial reusability, capable of returning to its launch site or drone ship. Its second stage, however, presents a novel approach: payloads emerge from clam-shell-like fairings, dubbed the "Hungry Hippo" system, for a final orbital push. A vacuum-optimized Archimedes (AVac) engine, taller and more powerful than its first-stage counterparts in space, propels this final stage.
Overcoming Setbacks and Future Outlook
Despite previous timeline adjustments and a tank rupture incident in January at the Wallops, Virginia, facility, Rocket Lab CEO Peter Beck has consistently affirmed the team's dedication to achieving orbit only when the vehicle is fully ready, prioritizing readiness over arbitrary deadlines. This steadfast approach, it seems, guides the company's development trajectory.
