Archimedes second stage engine full duration burn - complete ✅ (and what a thing of beauty). The AVac (Archimedes Vacuum) engine produces 1.2x lbf of its Stage 1 variant and stands ~2.5m taller thanks to its extended nozzle optimized for the vacuum conditions of space. Recent AVac testing included a stub skirt for the nozzle. Since full length vacuum nozzles at ground level risk flow separation and instability, stub skirts are used to anchor our engineers' analysis for how the engine will perform with the full nozzle in vacuum conditions - all critical preparation for Neutron's first flight.

E-2 has successfully demonstrated a full mission duty cycle with margin, completing a 201 sec run at our Mojave, CA test site. Multiple 200+ sec test fires have now been completed, proving performance and reliability across engine builds. As the highest performance LOX/kerosene engine in the small launch class, E-2 is designed to maximize your payload capacity and unlock more value from every mission to orbit.

Last week, we pushed our Hadfield MK IV engine and Darkhorse engine test cell to their limits ahead of our upcoming thrust vector control (TVC) and orbital engine test campaigns. It was thrilling to see this controlled test go sideways — literally! Orbital launch vehicles operate within narrow design margins and constrained safety factors, where excess mass in any subsystem directly impacts payload capacity or mission viability. Destructive and limit testing enable us to validate optimal mass-performance trade-offs across propulsion, pressure systems, and primary structures. Key outcomes from this test include: ✅ Structural margins validated – Darkhorse demonstrated stable operation under full thrust loads at gimbal angles exceeding design specifications ✅ Thermal performance characterized – Extended burn duration at off-nominal mixture ratios provided empirical data on regenerative cooling degradation modes and injector thermal limits ✅ Fault tolerance demonstrated – Engine maintained functionality despite progressive damage, validating robustness for anomalous flight conditions ✅ TVC readiness confirmed – Test results validate system integration for upcoming actuated TVC test series l Design optimization insights – Failure mode analysis generated actionable improvements for cooling architecture, injector design, thrust structures, and engine reusability At NordSpace, we push limits. Canada needs to get to orbit with sovereign light-lift launch by 2028 and medium-lift launch by the early 2030s. The only way this is possible is through extreme levels of testing, manufacturing, and investment. Our mission to build a Canadian end-to-end space missions capability will change the shape of our nation both on Earth and in space. If you would like to join our mission, please apply for a role at NordSpace via the Careers page on our website, and join us at the Canadian Space Launch Conference on May 5th, in Ottawa.

Who has ever seen a LOX/Kerosene liquid 🚀 engine with a blue plume 💎💎💎💎? Not only does it look spectacular, but it also serves as undeniable proof of the 99%+ combustion efficiency achieved in this test. Enjoy this 3-minute, 20-second test of E-2, a mostly 3D-printed 22k lbf (10 tf) ORSC LOX/Kerosene liquid rocket engine. Nominal pressure: 100 bar; mixture ratio: 2.7. Recorded today at Stennis Space Center, this test also secured the duration record for the test stand. E-2 is now available for sale to launch companies.

Over the past weeks, we have continued advancing the Gas Generator Qualification campaign to ensure this hardware is fully ready for flight. Our Qualification Model (QM) Gas Generator has successfully accumulated over 15 minutes of operating time across 20 test runs, covering all launch and re-entry scenarios. These tests included: ▪️Ignition and short-duration burn (5 s) ▪️Medium engine running time (20 s) ▪️Stage 1 nominal burn duration (40 s) ▪️Longest Burn (LB) for engine duty cycle ▪️Extended burn (+10%) for qualification margins With more than 15 minutes of accumulated runtime, this Gas Generator has operated at over 400% of a single mission requirement, including simulations of 3 booster re-entry burns, preparing the hardware for reusability conditions. Hardware reliability is a must, and with all those tests, PLD Space can better determine when if hardware can fail during the process and introduce improvements that allow MIURA 5 to a successful mission 🚀
