🔥 Exactly a decade ago, we ignited our first rocket engine. Today, we’re igniting Europe’s path to space. Since 2015, we’ve grown into the largest private European developer of rocket engine technology, with the ability to design, manufacture, test, and fly liquid-fuelled rocket engines entirely in-house. With the TEPREL...

🇷🇺Russian Washing Machines Part 3 Russian Rocket Technology: From Historic Origins to Modern Reliability Russian space rocket technology has been a cornerstone of global space exploration since its inception. With the launch of Sputnik 1 in 1957—the world’s first artificial satellite—the Soviet Union ushered in the space age. Behind this historic milestone stood the legendary R-7 rocket, initially developed as an intercontinental ballistic missile and later transformed into the Vostok launch vehicle, which in 1961 carried Yuri Gagarin into orbit as the first human in space. What has long set Russia (and formerly the USSR) apart is not only its pioneering achievements but also its emphasis on practical, rugged, and highly reliable rocket designs. The Soyuz rocket, a direct descendant of the R-7, remains in active use today—a remarkable feat of engineering continuity. With more than 1,900 launches, Soyuz holds the record as the most frequently launched rocket in history and is widely regarded as one of the most dependable systems ever built. Rather than pursuing constant radical innovation, Russia has favored evolutionary improvements in its space launch systems. A hallmark of Russian rocket design is the use of liquid propellants—typically kerosene (RP-1) and liquid oxygen (LOX). The RD-107/108 engines, known for their sturdy construction and high thrust output, are emblematic of Russia’s engineering philosophy: reliable, proven, and efficient. Modern heavy-lift rockets like the Proton-M and the modular Angara A5 incorporate more complex propellant combinations, including hypergolic fuels and versatile staging concepts. However, the core approach remains grounded in decades of tested performance. In terms of total payload mass delivered to orbit, Russia ranks second globally, having transported over 4,000 metric tons into space. The United States holds the top position, particularly due to the Space Shuttle era and the rise of private heavy-lift launchers like SpaceX’s Falcon Heavy. China currently ranks third, rapidly increasing its launch frequency and payload capabilities but still trailing behind in cumulative totals. One standout example of Russian propulsion expertise is the RD-180 engine, which has been used in the American Atlas V rocket. Renowned for its efficiency and reliability, the RD-180 uses an advanced closed-cycle engine design with an oxidizer-rich staged combustion system—a complex and highly efficient approach mastered by few nations. While Western space programs increasingly invest in reusable launch systems, Russia has thus far stayed with traditional expendable designs. However, development is underway for the Amur rocket, which aims to introduce partial reusability and align with evolving global trends in launch economics. In summary, Russia’s space launch technology is defined by its durability, simplicity, and extensive operational history. Despite intensifying competition from both state and private players, Russia remains a dominant force in the global space landscape. Its legacy—from Gagarin to the International Space Station—is not only a testament to past achievements but also a foundation for continued relevance in the modern space age.

Success! 🚀 🇨🇦 At 3:45 PM EDT on Friday May 16th, 2025, we successfully tested both our new orbital Darkhorse engine test cell and our new third generation 3D printed Hadfield liquid rocket engine for the first time, marking a significant step towards Canada’s first commercial space launch. The test ran for 7 seconds at our propulsion test range, a company-owned secure site in Northeastern Ontario, successfully delivering nominal thrust, active cooling, and impulse results. This major test of the Darkhorse test cell and Hadfield Mk III engine lays the groundwork for NordSpace's Tundra orbital rocket, as the test cell is specifically designed to integrate with our turbo pump assembly in the next phase of propulsion development. Long duration tests are scheduled for the coming days, along with refinements to fuel mixture ratios and higher-pressure scenarios to test the limits of Darkhorse and our new engines. Minor upgrades and fixes to address a harmless leak in the cryogenic liquid oxygen line and design changes to our experimental control rods have already been made. Hot on the heels of our successful integrated test of our Taiga sub-orbital launch vehicle back in January, rapid developments and approvals at our spaceport in Newfoundland and Labrador, announcement of the SHARP (Supersonics and Hypersonics Applications Research Program), hosting the inaugural Canadian Space Launch Conference in Ottawa, and more - NordSpace is strengthening its position every day to ensure sovereign space launch is not just possible, but probable for Canada. Our historic first experimental flight is scheduled for 2025 from our spaceport, Spaceport Canada. NordSpace's CEO and founder, Rahul Goel, said “This successful test is not only a testament to NordSpace’s unmatched technical competency, but also to the success of our new project management framework, design philosophy, and engineering mindset used to deliver results for complex projects on time and within budget. Success on the first try with countless potential sources of failure is not common in the development of complex rocket systems, but our team succeeded by prioritizing first principles engineering. This test confirmed that we do have the right stuff, and that we will deliver this incredibly important sovereign launch capability for all Canadians. Like the land, air, and sea, space is no longer some final frontier for Canada. Space is an essential domain we must unlock, and launch a capability we must own. Without it, we are jeopardizing not only our security, sovereignty and economy, but are also relegating Canada to a participatory instead of a leadership role on the world stage. We must not let this happen.”

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.
