FORGET FIREWORKS, THE REAL LIGHT SHOW MAY BE AMERICA’S NUCLEAR ROCKET While the world is busy counting down with champagne and drone shows, the U.S. government quietly lit something far brighter. The Department of Energy and NASA made it official. Nuclear Thermal Propulsion is no longer a science project. This is the moment chemical rockets start looking like steam engines. Nuclear Thermal Propulsion doesn’t burn fuel. It cheats physics the old-fashioned way. Liquid hydrogen gets blasted through a nuclear reactor, uranium atoms split, heat explodes outward, and the hydrogen screams out the back at absurd speeds. No combustion. No oxidizer. Just raw nuclear heat turned into thrust. The payoff is brutal and obvious. It delivers roughly double the efficiency of chemical rockets. That means fewer launches, heavier payloads, and much shorter trips. Mars stops being a nine month radiation marathon and starts looking like a three to six month sprint as the tech matures. Less time in deep space. Less exposure. More margin for humans to survive the trip. Faster travel keeps astronauts alive. Higher efficiency makes sustained missions possible. And nuclear propulsion is the only tool on the table that actually scales beyond flags and footprints. Now zoom out. SpaceX already solved the hardest problem in rocketry. Cost to orbit. Starship is the freight train. Nuclear propulsion is the engine swap that turns that train into an express. Chemical rockets get you off Earth. Nuclear engines move civilization through the solar system. Source: Office of Nuclear Energy | US Department of Energy

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.

Helion energy is building what will be the world’s first commercial fusion power plant, scheduled to be finished in 3 years. Great interview by Lex Fridman with David Kirtley (CEO of Helion). Most power plants are heat engines. You burn fuel or run fission, boil water, spin a turbine, and get about 35% electricity while the rest leaves as waste heat. Helion flips the flow. The fusion reaction makes charged particles that push back on a magnetic field tied to a capacitor bank, so you get direct electricity instead of a steam loop. That path can reach about 85% efficiency from fusion energy to electrical output, which means less conversion gear and tighter control over power delivery. 🧪 How the machine works A giant capacitor bank drives coils that both accelerate and squeeze plasma. Two plasmas, deuterium plus helium‑3, are launched from opposite sides and collide in the center. By rapidly reversing the magnetic field in about 1 microsecond, the plasma self-organizes into a field‑reversed configuration that traps itself. Then the machine compresses it hard. Fusion happens, new charged particles appear, and their pressure pushes the magnetic field so the system dumps energy back into the capacitors. It is pulsed, up to 100Hz in tests, so each shot is a clean measure of input versus recovered electricity. 🛡️ Safety and waste There is no chain reaction. The device only holds about 1 second of fuel at any time, so stopping the drive stops fusion. X‑rays and some neutrons exist during operation, so you use shielding and standard controls, similar to particle‑accelerator facilities. When the pulse stops, the radiation source stops. 🖥️ Why data centers care The output is high‑voltage DC sitting on capacitors. You can invert to AC for the grid, or route DC with fewer conversions into rectifier buses for racks. That cuts losses and simplifies backup. The company is targeting 2028 for a first grid-tied plant for a large buyer, which lines up with growing AI power needs. 🧩 What is still hard Helium‑3 is scarce on Earth, so you must produce it or source it. This fuel also likes higher temperatures, roughly 200M-300M degrees, so the pulsed magnets and power electronics must be very fast and very tough. Stability is managed by giving the plasma enough “spin” and length so it behaves like a fast top that stays upright, plus thousands of synchronized switches that fire with microsecond timing. If this architecture keeps showing pulse gain and high‑efficiency recovery, you get a compact generator that skips steam, feeds a capacitor, and delivers clean power in the exact format modern compute wants.

Here’s a reason why this is happening that no one is talking about A worldwide energy infrastructure reset has been underway for some time now We’re entering the later stages of this transition where nations and institutions are jockeying for position to benefit the most on the other side of the transition The battle is to secure inputs for EVs, magnets, batteries, semiconductors, defense systems, and grid equipment Of course these materials will fuel the next stage of energy production and distribution Like SMR’s (Small Modular Reactors) which will likely play a major role To slow down the competition, we have been subject to attacks on the most important commodities that are needed to win the race This is why oil, gas, refining, and shipping chokepoints have been the subject of destruction all over the world in recent weeks What the news tells us as the reasons for this phenomenon is mere propaganda Japan is advancing deep sea rare-earth extraction near Minamitorishima, with reports that the mud there contains very large quantities of yttrium and dysprosium These rare earth materials are needed for performance electronics, energy systems, and advanced materials, especially where heat resistance, magnet strength, and precision optics are required Japan is an ally to America China on the other hand has just announced major new finds in Sichuan including fluorite which is very important in parts of the semiconductor and battery supply chain But in an energy transition, economies still depend heavily on refining capacity The IEA has warned that the current Middle East damage is a major threat precisely because oil and gas infrastructure remains systemically import So these kinds of events like the one here in Valero aren’t likely a total controlled demolition of these sites But they may be strategic attacks by our competitors to slow down the capacity to move the materials around to get ahead in the transitional period Stay watchful ✝️

This isn't alien technology, literally or metaphorically. The breakthrough here isn't in engineering at all — it's in corporate organization. See, most machines are broken because the organizations that make them are broken. As an engineer, I would estimate that at least 30% of the parts of any given device exist only to correct for the design flaws in the other 70%. Works like this. Suppose I, an engineer, design a set of pipes and injectors to feed fuel to a combustion chamber at a consistent and controllable rate. Except in testing, there's some corner cases it doesn't handle well. Now, if you're an engineer, you understand this is normal. Nobody ever gets a design right the first time, unless it's so trivial that it's probably been done before. Your first design doesn't survive the wind tunnel, your first code doesn't compile right away, and if does, it segfaults. Your rockets blow up. And there's a flow problem with your fuel feed lines. It happens. Doesn't mean you're stupid. Means you didn't have enough information. But you have an even bigger problem. Middle management. Middle management is a special variety of hazmat suit, which is worn by the finance, sales, or market guys who run companies, so they don't have to touch the icky engineers. C-suite guys hate hate hate engineers, because it's a terrifying sensation to be dependent on someone you cannot understand, who doesn't appear to respect you much. (It does not occur to them that it is also extremely frustrating to have your work paid for, and thus controlled, by someone who cannot understand what you do, who doesn't appear to respect you much.) The primary role of middle management is talk to engineers so C-suite guys won't have to, and the primary qualification is to be a member of the right social class, and to hate engineers. This qualification is dressed up in secret handshake buzzwords like "management experience", as used in the sentence "I know you have been an engineer for twenty years and the other engineers all come to you for advice and leadership, but you don't have management experience, so I am going to hire my golfing buddy's 23 year old kid, who just graduated business school." So the fact that the fuel lines lines are not working quite right isn't your problem. That's part of the normal engineering process. Your problem is that your manager hates you and everything you stand for, and doesn't trust you or take your word for anything. He think his job is to keep you in line rather than help or empower you. So when you say "the fuel feed lines need to be redesigned", he says "we already spent six months and seventeen million dollars design the fuel feed system, we can't let you do it again." He thinks you are telling him seventeen million dollars worth of work needs to be thrown away and redone, and he cannot be told otherwise, because he cannot be told anything. So he says "you have two weeks and fifty thousand dollars to fix it". So you add another turbopump. What else can you do in two weeks? Now there's a new part. And if something goes wrong with that, another new part will be added to fix it. Because the company's actual priority isn't what you are responsible for — the design. It's what middle management is responsible for — the schedule and the budget. You have to play the villain so they can play the hero. What middle management doesn't understand, is paid to not understand, is what engineering actually is. Engineering is the process of making mistakes until you run out of mistakes to make. So when you spend six months and seventeen million dollars, and ended up with a design that doesn't quite work right in all cases, you weren't throwing away money, you were burning through mistakes. You've gotten a lot of them out of the way and won't make them again. But you have to get rid of some more before the design is actually right and doesn't require extra parts. The work of engineering isn't making the thing. It's teaching yourself to make the thing. Once you've done that, you can make the thing with minimal effort and time, because you know how to make the thing. C-suite financiers would hate this idea if they understood it. Why? Because it's unpredictable. Financiers like safe investments that make money. Not knowing how long something will take or how much it will cost is terrifying to them. So they train engineers to lie to them, by hiring a middle managers who try to force them to lie, and just interpret every guess as a promise if engineers still refuse to do so. But lying to yourself doesn't make the truth go away. The truth is that engineering projects take as long as they take, and cost as much as they cost. And that no one knows how long or how much they will be, because no one knows how many mistakes are waiting to be made, until they actually make them. The only thing you thing you can do about this is hire really good engineers, who catch more of their mistakes on the white board, leaving fewer to be caught in the wind tunnel, and this makes engineering faster... but it doesn't make engineering more predictable. Gantt charts are nothing but a collection of lies that corporations have taught themselves to tell themselves, lies that middle managers try to make true by enforcing them as promises. The ultimate reason that machines are 30% unnecessary parts is that the corporations that build them are 30% unnecessary people. This is what's different about Elon Musk. It's not that he's a better engineer. It's that he's a better manager. He understands engineers and engineering, and he doesn't hate them because he is one. He understood all along that green-field design is full of unknown-unknowns, and that there is absolutely no number-crunching, pie-chart, MBA magic that can eliminate this risk... it can only be hidden from view. The critical understanding is in the video clip below, where he says that SpaceX only had a 10% chance of success. You cannot say something like that unless you get it. And when you get it, you are free. Free from artificial anxiety about schedules and budgets. Anxiety about schedules and budgets is based on the delusion of control. Managers can't make a project finish "on time". They never could. The only power they have is the power to screw it up. The fate of a project is already written in the unknown unknowns before it ever starts. And the best, the absolute best, an engineering team can ever do, under any circumstances, is to confront those unknowns with clear-eyed honesty, and a willingness to adapt. Well, when you say to yourself, "This project has a 10% chance of succeeding", you've already confronted the pain of those admissions, which means you have already conquered the fear. The fear that makes you try to treat a prediction as a promise. The fear that makes you insert an extra turbopump, when what you really need to do is get busy redesigning the pipes, even though you have no idea how long it will take or much it will cost. Even when your rockets blow up. The SpaceX Raptor engine isn't just, or even primarily, a triumph of engineering smarts. It's a triumph of character. It's about an entire team with virtues MBAs lack: self-awareness, persistence, courage, humility, and, ultimately, hope. Because that's what it takes to pursue the best design, the RIGHT design, not even knowing if it exists to be found, much less whether you'll find it before you run out of money. Great things are not accomplished by middle managers with spreadsheets and Gantt charts. They are accomplished by teams of experts with passion and vision. Who are willing to risk failure so they can succeed. So what's the point in me saying all this? Am I just writing a puff piece on SpaceX and the Raptor engine? No. The point is that this is not special, one-off, magic alien technology. It's the systematic result of a correct understanding of engineering. Which means that EVERY COMPANY CAN BE LIKE THIS. If the people who control the purse strings are willing to learn from this example, and stop managing with spreadsheets and fear.

Elon Musk: My initial plan was not to start a rocket company. I just wanted to fund a one-time Oasis mission to Mars. “I started off initially with the idea of doing something in the space exploration arena. In fact, it wasn't actually with the idea of creating a company. It was initially with the thought of spurring interest in sending people to Mars. So I put together this idea called Mars Oasis, which was to send a small greenhouse to the surface of Mars and get people excited about the idea of going there and thus increase NASA's budget in order to make it happen. As I got more and more into that, I discovered that the real issue was that the cost of space transportation was really high, and it was getting worse. So we're used to technology getting better every year, but in some arenas it actually does not. It gets worse, particularly when you consider that in 1969 we were able to go to the moon and then we were unable to go beyond low Earth orbit. And now with the space shuttle retired, we're not even able to go to Earth orbit at all, even with people. That was not the right trajectory. So I actually went to Russia three times to look at buying an ICBM to launch this mission. Just very crazy. After my third trip of trying to negotiate with the Russians to buy an ICBM and I did actually get a deal, so figured out what it would cost and everything. But I concluded that my initial assumption had been wrong, that it was not a question of trying to generate more will to explore. Because I think the United States in particular is distillation of the human spirit of exploration. Space exploration is fundamental to the American psyche. But people really need to believe that it can be done and it's not going to break the bank if it does. So that's when I decided to start a rocket company. And I actually didn't think it would succeed and it almost didn't. We started off developing a small rocket which was kind of a scale model version. It was about 100,000 pounds of thrust. So big, you know, big, big by normal standards, but small for a rocket. And developed the engine and the airframe and the electronics and the guidance control system and then proceeded to have three failed launches in a row. And so for various technical reasons, the first three launches did not succeed in reaching orbit. Launches two and three did get to space, but they didn't achieve enough speed to reach orbital velocity. So this is 2008. And so we were heading into the recession and we had one rocket left. And fortunately in late 2008, that fourth launch did work and we made it to orbit. And then we won a NASA contract after that. And so fortunately things worked out. But if that fourth launch had not worked, then SpaceX wouldn't be around. So it was very close call. In fact, when I started I thought, okay, I've got enough money, I think I've got enough money for three launches. Fortunately, it was just enough to make that fourth one.” Montana Jobs Summit, September 16, 2013

Today, I taught my kids principle of the combustion engine focused on the crank shaft. We started by having them in groups brainstorm how they believe an engine works, then I simplified it for them, and at the end, have them create small models using toys. First, these are my kids, they are in primary 2 (8 years old). I started with them 2 years ago when they were 6 years old and most of them couldn’t even write their names. We can also do this in Nigeria: 1. Kids are all born the same, but the right nutrition at early age helps cognitive development. Let’s build stable local industries that focus on production of children meals that are rich in proteins and vitamins that are good for the children’s brain development. Too much pap and two which are carbohydrates rich aren’t sufficient, and can affect academic performance of children, whom eventually grow up to be the politicians that think giving poor people giveaways in comment sections is helping the economy. 2. Primary education is way too important to be treated as political privilege or achievement. All the countries that invested in their children such as Japan, China, US, Singapore, Finland have far superior economies and quality of life compared to the countries that didn’t. Teachers are not just civil servants, they are looked at as heroes, soldiers, critical individuals that make or break a society. They earn well, they are taken cared of and they are some of the most intelligent and creative people in a country. A keke driver knows how important his Keke is so he can make money, so he takes care of it. Don’t take care of primary school teachers, you should prepare for poverty and insecurity. Playing the blame game on political parties or candidates and insulting each other on the internet only takes our minds away from what is important. Let’s put aside political, religious, ethnic and sentimental differences and prepare a future for our children and grandchildren so they wouldn’t be slaves to my students in the future. The Nigerian education system and curriculum right now is as good as nothing. 3. Skills are part of education/degree: It is unfortunate that a former student who had so many carryovers in mathematics (which is the backbone of computer science) and barely graduated and purchased highest education certificates is confusing and discouraging people who are putting their sweat and time to get a difficult, expensive and ancient degrees in Nigeria. Considering how he failed many courses so many times, it’s not surprising that he is taking a shot at university education. Well, skills are part of degrees in normal and functioning universities and education systems with updated curriculums that fits its economy. In fact, those skills start from primary school, and I believe the professor should advocate for updated curriculums that include more modern skills, practicals, field trips, work attachments that will jumpstart Nigeria’s failing economy not destroy the little that is left in degrees and the hope millions of poor citizens have for them. 4. Native language is the way to go: Yes Nigeria has many languages, so we can use multiple official local languages in different regions to educate and run the government. English can be an optional subject in school which parents can choose. Sacrifice has to be made in order to develop, so some smaller ethnic groups that have few speakers should adopt one of the major languages in Nigeria as a secondary language to be used at home, and that would the language to use at school. Controversial? Yes, but the advantages far outweigh the disadvantages. The past is the past, we can only learn from it. Let’s use these lessons and start building a better future for our children and grandchildren now. Prayers are good, but they aren’t enough and shouldn’t take most of our time and energy. We have to physically work harder than we pray.

The situation in British Columbia has reached a breaking point, and Question Period today laid it bare. I pressed Premier David Eby on the simple, unavoidable truth: under his government, major economic opportunities are slipping away, families are leaving in staggering numbers, and investors are looking south for stability they no longer find here. I pointed out what everyone can already see. Trade with the United States is rising, but our access to Asia is stagnating. Energy projects capable of delivering world-priced returns are being blocked. Seventy thousand people have left this province in the last year alone. And now Nutrien, one of the most significant resource players on the continent, has chosen to invest more than a billion dollars in Washington State rather than here in British Columbia. That decision didn’t happen by accident. Even Saskatchewan’s Premier has warned Eby about the dangerous rhetoric and divisive politics coming out of this government. Investors, premiers, and industry leaders across Canada are signaling the same thing: they don’t trust the direction British Columbia is heading. Yet instead of acknowledging any responsibility, Eby tried to dodge and deny. He disputed basic facts and insisted the province is in a period of “epic population growth,” a claim that would surprise the tens of thousands of British Columbians who’ve already left. And after admitting that Nutrien’s decision is “deeply disturbing,” he immediately shifted blame, claiming no one ever told him the project was in jeopardy. In my response, I made it clear that the conversations I’ve had with Saskatchewan tell a very different story. They’re deeply concerned about how impossible it has become to move major projects forward in this province. And Nutrien’s own stated reasons, congestion, bottlenecks, labour instability, reliability problems, and above all, uncertainty, point directly at this government’s policies. The Premier’s answer was to lecture the province on how to pronounce the company’s name and to repeat how many “major projects” he believes are on the books. But none of that changes the reality: when a global company wants to invest a billion dollars, they look for stable rules, predictable permitting, and governments that don’t rewrite the map every six months. They don’t find that in British Columbia anymore. What I made clear today is that this failure matters. It means lost jobs, lost investment, and lost confidence, consequences that British Columbians will bear long after this news cycle ends. The government had the tools to keep this opportunity in British Columbia. They used none of them. And until that changes, more of these opportunities will keep crossing the border. #cdnpoli #bcpoli

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.”
