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.

Canada's first orbital-class rocket engine is now being manufactured! Our patent pending Hadfield-150 engine is the largest and most powerful rocket engine ever built in Canada, and the first known Canadian orbital-class engine to make it to this stage. The Hadfield-150 builds on everything we learned after years of painstakingly designing, manufacturing, and testing the Hadfield-10 series, our first regeneratively cooled and additively manufactured liquid rocket engine. Every engine test, both successful and unsuccessful on our Darkhorse test stand at Area 66, retired risk that's now carried straight into Hadfield-150 and sovereign orbital launch for Canada. A few details about the Hadfield-150 engine series: ✅ Designed to power Tundra and Tundra+, our light and medium-lift launch vehicles, and built to scale to Tempest, our larger reusable medium lift vehicle ✅ Manufactured entirely in-house, from design to print to test, for true sovereign launch capability ✅ Produced at Rocket Factory 1, on our expanding fleet of metal additive manufacturing systems at the AMA Lab, including the largest known metal 3D printer in Canada ✅ Designed for reusability and medium-lift scale from the outset, and built to significantly cut the time, infrastructure, manufacturing and cost iterative engine testing usually requires, with room to scale to even larger engines by leveraging the same design ✅ Capable of engine-out functionality, so losing one on an early flight doesn't have to mean losing the mission ✅ Optimized for Canada's Launch the North initiative, to deliver sovereign operational capability in a time and cost efficient manner Initial testing starts later this year at our new Blackhawk orbital engine test cell at Area 66, our private test range in Ontario. Stacked, integrated vehicle testing comes later at the Atlantic Spaceport Complex, our spaceport in Newfoundland and Labrador. Stay tuned for some exciting and fiery milestones ahead! 🚀🇨🇦 National Defence Defence Research and Development Canada Canadian Space Agency Transport Canada NGen Canada

SpaceX Starship reached orbit for the first time on its 14th test flight and successfully deploying 26 next- generation Starlink V3 satellites. 🇺🇸 The number that matters most here is six, not one. Starship's upper stage carries six Raptor engines specifically so that losing one mid ascent doesn't end the mission, and Flight 14 is the first time that design assumption has actually been tested in the exact scenario it was built for: an engine dropping out early in the climb, on a flight that then still reached orbit and completed its full satellite deployment. That's a meaningfully different story from a rocket surviving a problem by luck; it's a rocket surviving a problem because the vehicle was designed with enough margin to absorb it, which is precisely the case SpaceX has been making for building Starship with engine out capacity in the first place.

With rocket engines, boring is good. To that end, please enjoy this 1,030-second (17+ min!) BE-7 engine burn. This test represents the Apogee Raise Maneuver or ARM burn for our Blue Moon Mark 1 Lunar lander, plus margin, the longest burn required by the mission to reach the Moon. You may have noticed that the engine for this test does not have a nozzle. BE‑7 is tested in both vacuum and atmospheric conditions. This test was at GEEx—our atmospheric test position in West Texas.

E-2’s first 90-second test fire was a success! It performed at 55% power with a low conservative 1.6 mixture ratio as planned. The hardware appears in perfect condition ready for more tests. This is an exceptional result for a first test article (E-2 SN1). The test was also a key milestone for our US Space Force TACFI contract. We’ve wrapped up this test campaign and will be back in January with an updated injector featuring lower LOX passage pressure drop to allow us to increase the LOX mass flow and in turn reach full thrust and high performance O/F mixture ratio of 2.62. We thank our team and partners for making this possible - especially Stennis Space Center and their team. We would also like to thank the @SpaceForceDoD for their TACFI contract support.
