The more companies, engineers and tech you put into the space age, the sturdier the economy that opens up. Iteration is how you correct and learn. That path works. And it teaches.

Rapid build test learn is such a great approach. A much better approach vs review and analyze ad nauseam in hopes of one shotting a build. There's important learning that comes from build and test, and the quicker you can realize that it greatly helps the development.

Here is one of our experimental 3D printed Hadfield liquid rocket engines going through some thrust vector control (TVC) profiles! As we scale to our first light-lift orbital launch vehicle, Tundra, and then our medium-lift reusable launch vehicle, Titan, precise control of the rocket at every phase of flight is critical to mission success. Guiding a rocket to orbit, and eventually back to Earth, demands close coordination across every sub-team. Some of the key challenges we’re tackling: ➡️ Reliable & repeatable TVC actuation: ensuring the engine gimbal responds consistently across every test and flight ➡️ High-frequency control loops: real-time systems that keep the vehicle stable from liftoff to orbital insertion ➡️ Propellant sloshing: accounting for the movement of fluids in tanks and its effect on vehicle dynamics ➡️ Wind shear compensation: countering atmospheric disturbances during ascent ➡️ Structural bending & flex modes: managing how the vehicle’s primary structure responds to aerodynamic and thrust loads ➡️ Precision payload delivery: hitting the exact target orbit, every time Our team at NordSpace has been advancing our propulsion systems on many fronts, as we work to unveil our orbital-scale, pump-fed Hadfield and Garneau rocket engines in the near future — the engines that will carry Canada to orbit for the first time, and unlock sovereign access to space. Check out some of our rocket hardware, meet our engineers, join over 400 attendees and over 40 speakers at the Canadian Space Launch Conference, taking place this May 5th in Ottawa.

Carney: Now, above all, we will build Canadian. The new security threats reaching our shores mean we’re making the biggest investments in our military in generations. But up until now, more than 70 cents of every dollar of military capital spending by our government has gone to the United States. With our new Defense Investment Agency, we’ll make sure we build more of our security and defense capabilities here at home—creating new careers in aerospace, shipbuilding, cyber, and AI for Canadian engineers, technicians, and scientists. It’s the same thing with steel. Consider that while 80% of the steel Europe buys is manufactured in Europe, and 75% of the steel the U.S. buys is made in the U.S., only 40% of the steel we use is made here. That doesn’t make sense—not when we have the people, the resources, and the companies to build right here in Canada. So, our upcoming budget will move forward with our Buy Canadian policy—prioritizing Canadian steel, aluminum, lumber, manufactured goods, and technology for Canadian projects. With new orders for homes, infrastructure, and defense equipment becoming orders for Canadian suppliers, we will be our own best customer

For the second time, Ursa Major has successfully fired our 10” solid rocket motor with highly loaded grain showing repeatable results with rapid iteration, as seen in the motor start up. On the topic, Bill Murray, Vice President of Product and Engineering for Solid Missiles Systems said, “At Ursa Major, we demand rigor, quality, and repeatable results. While we embrace the learning that comes from testing and iteration, our ultimate goal is nothing short of perfection. In just months, we've scaled and successfully static fired our highly loaded grain solid rocket motors from 2.75” to 5” to 7” and now to 10”. This is in addition to our four successful SRM flight tests. This rapid progression exemplifies Lynx: the future of American solid rocket motor manufacturing. By strategically deploying additive manufacturing and advanced propellant technologies, we achieve in months what traditionally takes years. Long lead times of two or more years for SRMs are no longer acceptable. Our warfighters need reliable, high-performance solutions today, and Ursa Major is prepared to deliver.” #FlyFaster

A few months ago we set out to understand exactly how our models can be used to accelerate progress in robotics and other AI systems that don’t just represent the world, but are actually able to interact with it. We’ve been collaborating with leading companies in the space and we’ve developed an initial approach that we're now opening up to accelerate development across the industry. Our fifth announcement is GWM Robotics. GWM Robotics is a learned simulator that generates synthetic data for scalable robot training and policy evaluation, removing the bottlenecks of physical hardware.

After years of development, testing and refinement, we are printing one of our last Hadfield-10 rocket engines, a bittersweet moment 🫡 More of our team is transitioning toward getting our much larger orbital-class Hadfield-100 engine ready for the test stand, and getting Canada to orbit for the first time with our Tundra rocket. The pressure-fed Hadfield-10 series has been the backbone of NordSpace's propulsion program since our earliest days. It's the engine that proved we could design, manufacture, test and fly liquid rocket engines from scratch, entirely in-house, at the pace necessary to reach orbit. It powered our first successful hot-fire tests, survived our most demanding qualification campaigns, and gave our team the hard-won knowledge that no textbook or simulation could provide. It also powers our Taiga sub-orbital vehicle, which is taking flight in a few weeks. Every experimental lesson learned in its development from combustion stability, regenerative cooling, additive manufacturing, and test operations lives on in what comes next. That knowledge now flows directly into our turbopump fed Hadfield-100 engine, the most powerful rocket engine in Canadian history. Designed to power our orbital Tundra rocket to deliver 500+ kg to LEO and scaling further to 1,100 kg LEO in the Tundra+ configuration. Architected from day one to grow to the thrust levels required for our reusable Titan medium-lift vehicle targeting 5,000+ kg to LEO while striking the right balance between performance, scalability, heritage, and speed of development to meet the Government of Canada's targets. The Hadfield-10's design will also form the foundation of our SHARP Sabre hypersonic rocket's M2S-HyRock engine. The full shift to the Hadfield-100 is a major milestone for us, and it's not just about more powerful engines. The infrastructure we're developing from moving to a much larger facility, acquiring much larger metal 3D printers, developing new test cells, and pursuing rigorous standards all feed in to this next phase of growth for our program. To everyone on the NordSpace team who designed, printed, tested, and refined these engines across so many late nights, early mornings and weekends, thank you. This chapter made everything that follows possible, and the next one starts now.

We have 6 different models of CNC machines already designed and validated for production but we would need crores to scale up production and offer it to other manufacturers. Hence, we only build machines for our own production facility. Capital is a bottleneck for us. Currently we just have a tiny space within our own factory which is our R&D lab. We are a team of mere three people. Scaling hardware isn’t easy but it’s something that must be done for us to truly be self-reliant. Really appreciate your efforts Sridhar Vembu to build these hardware tools here. We must build more factories and hardware products in the country. Long way to go before I sleep.
