SpaceX’s Raptor engine didn’t just iterate on rocket design—it obliterated one of the biggest engineering nightmares in aerospace: turbopump cross-contamination. By splitting the oxygen and methane boost pumps onto completely separate, dual-shaft drives, engineers eliminated the catastrophic risk of volatile propellants leaking into each other under extreme chamber pressures. It’s the sheer mechanical brilliance behind Full-Flow Staged Combustion that finally made rapid rocket reusability a reality. #SpaceX #RaptorEngine #RocketEngineering #Aerospace #Starship #EngineeringExcellence #Propulsion #TechInnovation

I bet long term, SpaceX is going to be the default choice for overseas cargo deliveries, especially when Starship is proven to work. “Once you achieve full reusability, then it’s simply the cost of access to orbit is just the cost of propellant, because now you can reuse all aspects of the vehicle. The propellant we use for the Starship is liquid oxygen and liquid methane, which is the cheapest propellant you could possibly get. …So the cost of propellant for Starship will be less than the cost of jet aviation fuel, which means that you should be able to actually send cargo to space for less than the cost of cargo of an airplane going on a transoceanic trip.”

This is not a model engine pretending to be a jet engine. It is actually a complete gas turbine shrunk onto a test bench. Inside this small machine are a compressor, combustion chamber, turbine wheel, fuel system and digital engine controller, the same basic physics used in aircraft engines. At full power, this turbine reaches nearly 98,000 RPM over 1,600 revolutions every second while producing 280 N of thrust, equivalent to roughly 28 kg of pushing force. At nearly 98,000 RPM, even a tiny imbalance can destroy the turbine. The combustion chamber must survive exhaust temperatures approaching 700°C, while the fuel system continuously manages a core flame powerful enough to create 280 N of thrust without losing combustion stability. A high-end RC turbine can cost $7,000-20,000+, despite fitting on a workbench. It is nowhere near the complexity of a modern military turbofan with thousands of components, afterburners and advanced cooling systems. But that is what makes it fascinating, engineers have compressed the core mechanisms of a jet engine compression, combustion and expansion, into a machine small enough to hold. 📹 RC hobby

The secret to keeping Starship from ripping itself apart at 7,000+ MPH? It’s all about the "deep freeze." When SpaceX's Raptor engines ignite, they gulp down thousands of gallons of propellant every single second. At that insane flow rate, regular fuel would actually start to boil from the drop in pressure, creating deadly vapor bubbles—a phenomenon called cavitation. Think of it like microscopic pipe bombs violently imploding inside the fuel pumps, capable of shredding metal in seconds. By super-chilling the liquid oxygen and methane into a "sub-cooled," hyper-dense state, SpaceX drastically lowers the vapor pressure. Paired with a precision-engineered tank geometry that keeps the fluid perfectly packed, the propellant behaves like a rock-solid column of liquid under massive G-forces. No boiling, no bubbles, no cavitation—just pure, uninterrupted high-thrust power tearing through the upper atmosphere. #Starship #SpaceX #RocketScience #RaptorEngine #AerospaceEngineering #SciTech #HowItWorks #SpaceExploration

STARSHIP V3 SHIP 39: THE REUSE AUDITION BEGINS Everyone watches launches. Engineers watch the tests before them. Ship 39 just rolled from Mega Bay 2 to Massey’s test stand – engine bay empty on purpose. The Test Ladder: * Rollout complete – Ship 39 now sitting at Massey’s dedicated test stand * Cryo proof testing – tanks filled with liquid nitrogen to simulate brutal flight conditions * Pressure cycles – checking domes, tank walls, thrust structure and leaks * Structural stress – proving the ship can survive real propellant loads Pass that test and the real fun starts: * Install 6 Raptor 3 engines * Move to Orbital Launch Pad 2 * Full propellant load – liquid oxygen + methane * Static fires – first single engine, then all six This one is different. Ship 39 is the first flight-ready Block 3 Starship – taller, stronger, and built for reuse. If testing holds, it flies with Booster 19 on Flight 12. Target: March 2026. Source: Grok SpaceX

Chicago PD Superintendent delivers a brutal warning to Antifa: Threaten law enforcement, and they will not hesitate to use deadly force. So in other words… FAFO. “Federal agents, ICE, HSI, are officers. They are agents of law enforcement.” “When you plow into a vehicle that contains law enforcement agents, you're using deadly force. And they can use deadly force in response to stop you.” “If you box them in with vehicles, it is reasonable for them to believe that they are being ambushed and that this could end in a deadly situation. And it's reasonable for them to use force based on those conditions.”

I spend a small fortune on granola bars at the store… and I never once thought to just make them myself. This woman shows how easy it is: toast some oats, almonds, and pecans, melt butter, brown sugar, honey, and vanilla, mix it all together with dried cranberries and mini chocolate chips, press it into a pan, chill, and cut into bars. They look so much better (and fresher) than the packaged ones — and you can customize them any way you want. Why did it take me this long to figure this out?

Did you know it’s against “the rules” to even post a video humming inside this so called “antechamber?” Why wouldn’t they want people to hear the incredible acoustics that emanate from it? Could it be because we’re not supposed to know that this mini-chamber was an acoustical filter? As Christopher Dunn states in his book ‘The Giza Power Plant’ “After building the resonators and installing them inside the Grand Gallery, the ancient Egyptians would have wanted to focus a sound of specific frequency, that is, a pure or harmonic chord, into the King's Chamber. They would be assured of doing so if they installed an acoustic filter between the Grand Gallery and the King's Chamber. By installing baffles inside the Antechamber, sound waves traveling from the Grand Gallery through the passageway into the King's Chamber would be filtered as they passed through, allowing only a single frequency or harmonic of that frequency to enter the resonant chamber. Those sound waves with a wavelength that did not coincide with the dimensions between the baffles would be filtered out, thereby ensuring that no interference sound waves could enter the resonant King's Chamber to reduce the output of the system”

Elon Musk on Starship today: "The fundamental breakthrough of Starship is that it will be the first orbital rocket that is fully reusable, so this might sound like an obvious thing, but because in every other mode of transport, whether that's aircraft, cars, bicycles, horses, ships, these are all we take it for granted that they are reusable, an aircraft journey would be very expensive if you had to throw the plane away every time, and that's how rockets have been in the past, but it's very difficult from a technology standpoint to achieve full reusability for a rocket. We've got part of the way there with Falcon 9, but we'll get all the way there with Starship, and once you achieve full reusability, then it's simply a cost of access to orbit is just the cost of propellant, because now you can reuse all aspects of the vehicle, and the propellant we used for Starship is liquid oxygen and liquid methane, which is the cheapest propellant you could possibly get. The cost of propellant for Starship will be less than the cost of jet aviation fuel, which means that you should be able to actually send cargo to space for less than the cost of cargo on an airplane going on a transoceanic trip."

xAI is rolling out Skills on This new feature lets you create custom skills that Grok can reuse across conversations. Skills run inside Grok’s sandbox environment, so they can edit files, use your Connectors (Gmail, GitHub, Notion, etc.), run code, or perform any repeatable task you define. Once you create one, you simply tell Grok “use the [skill name] skill and do…” and it executes it instantly. You can also import skills.md files from other AI tools to bring them over quickly. It turns Grok from a one-shot chat tool into a more persistent, customizable workspace. This is a huge upgrade for anyone who uses Grok regularly.

McKinney, Texas Resident Protesting the Islamic Mosque: “Muslims force their way into countries and force their religion. If you don’t accept their religion, they kill you— you may say not all of them are radicals or extreme, to that I say what book, what person, and what source does their behavior come from? The Quran and prophet Muhammad— so unless they condemn the Quran and prophet Muhammad, they are all the same. How can we not see this? I know you all sit up there, and your hands might be tied because there isn’t much you can do, after all these people are using our own constitution against us.. what I say to you is STAND! Do what is right! Let there be a lawsuit. Let us stand together knowing God is on our side.”

We just launched a generative craft system inside Marble App. Kids can now create anything and turn it into a 3D object on their map. It's designed to be realistic, so kids have to use their brain to make things happen. It works like this: 1) You describe or sketch what you want to build 2) Marble creates a blueprint you can iterate on 3) You pick the resources and tools you think you need to make it (if you have them) 4) Marble crafts the object. If the build is successful and you can drop it on your map! Since you can create your own tools, there is no limit to what you can build with this system. So excited to see what kids make with it!

Great news!! A new significant milestone for #PangeaAerospace and ARCOS! We’ve successfully fired and validated our bio-methane and oxygen, bi-material combustion chamber that will power the ARCOS aerospike engine. It worked together with two types of single-piece injector heads designed for rapid reusability, easy inspection, and minimal refurbishment. We were also able to validate the advanced manufacturing techniques and materials used, which represent breakthrough technologies for the aerospace industry. They enable us to design and create the propulsion systems of the future much faster, with fewer parts, making them reusable, and achieving the best performance-to-cost ratio. This engine will serve any stage of a launcher providing unmatched performance, enabling reusability and a lower carbon footprint. It’s a pivotal milestone for creating the propulsion platform of the future, where high efficiency, reusability, and sustainability all collide into the same product. Thanks for your trust and for supporting innovative technologies, European Space Agency , @CDTI_innovacion Thanks, DLR - English DLR_de team for once again hosting our most important milestones. Special thanks to our strong partner AeniumEng , for helping us push the boundaries of what's possible, again! Congratulations to our unbeatable team, which knows how to overcome every challenge! Do not hesitate to contact us if you are interested in ARCOS or any of the technologies showcased. Enjoy these blue diamonds! 💎

My analogy of how Black women act Eddy from ED, Edd, Eddy is so spot on. They try to scam each part of the Black male work force into to taking care of them. Thank God it’s not working. And funny part is you can tell this mf ain’t got a blue collar man, she very un-kept.

This is very true. AI integration is both hard and necessary for companies. And AI-native junior employees can drive this adoption. Earlier this year Aaron Levie explained with martin_casado on the a16z podcast how AI fluency is one of the most powerful skills a new grad can have. The real value comes from knowing how to make AI work inside an organization. Most companies, both large and small, are slow to adopt new technology. They need people who can explain what AI can do, show them how to use it, and help them move faster. If you are fluent in AI, you can be that person. You can walk into a company, spot the areas where AI can save time or create new opportunities, and make it happen. That is a wedge into your first job and a way to stand out from everyone else.

🇺🇸 EX-CIA OFFICER: “THEY CAN MAKE YOU DRIVE INTO A TREE AND CALL IT SUICIDE” John Kiriakou, once inside the CIA, just reignited a massive debate about digital privacy, citing the 2017 Vault 7 leaks. Phones, cars, TVs, laptops - he says none of them are as private as we assume. “There was a dramatic leak in 2017 that the CIA came to call the Vault 7 disclosures - gigabytes worth of documents leaked by a CIA technology engineer. What he told us was that the CIA can intercept anything from anyone. They can remotely take control of your car to make you drive off a bridge into a tree to make you kill yourself and make it look like an accident. They can take over your smart television and turn the speaker into a microphone so that they can listen to what's being said in the room even when the TV is turned off.” Source: LADbible TV
