Watch Archimedes burn! Rocket Lab fires up engine for its powerful next-gen Neutron launcher (video)

Key Takeaways:

• Rocket Lab completed a full-duration static fire test of the Archimedes engine
• Archimedes will power the second stage of the company’s Neutron rocket
• Neutron represents Rocket Lab’s focus on a powerful next-generation launch vehicle
• “Stennis Space Center” appears as a keyword, indicating its relevance to the test
• Published by Yahoo! News on July 15, 2026, highlighting the timeliness of this milestone

Bold Step for Rocket Lab

Rocket Lab’s latest milestone involves a complete static fire test of its new Archimedes engine. Recently performed, this test ran for its full intended duration, demonstrating the engine’s capability to operate reliably under conditions similar to an actual launch.

The Archimedes Engine

At the heart of the company’s strategy is Archimedes, the engine selected to power Neutron’s second stage. While many details remain under wraps, the test confirms Rocket Lab’s confidence in Archimedes’ design and potential performance. The engine is expected to become a key driving force behind Rocket Lab’s ambitions in next-generation spaceflight.

The Neutron Rocket

Neutron is Rocket Lab’s planned rocket platform designed to offer greater power and versatility. With Archimedes guiding its second stage, the vehicle aims to deliver satellites and other payloads to orbit more efficiently than the company’s smaller Electron rocket. The successful engine test indicates progress toward a new era for Rocket Lab’s launch fleet.

Implications for Future Missions

With the engine test completed, Rocket Lab is one step closer to deploying Neutron in active service. Though the full details remain reserved for future announcements, this achievement underscores the company’s expanding capabilities. The reference to Stennis Space Center in the keywords hints at the center’s significance to Rocket Lab’s test or development plans.

Rocket Lab’s forward-looking approach continues to draw attention, and the Archimedes engine’s successful firing suggests its technology is maturing rapidly. As Neutron edges closer to reality, the spaceflight industry will be watching closely to see how Rocket Lab shapes the next generation of orbital launches.
