New rocket engine design, who’s this? #NASAMarshall propulsion engineers... designed the Rotating Detonation Rocket Engine (RDRE) that may one day power both human landers and interplanetary vehicles to deep space destinations! MORE:show more

NASA has developed and tested this Rotating Detonation Rocket... Engine (RDRE). Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, successfully tested a novel, 3D-printed RDRE for 251 seconds (or longer than four minutes), producing more than 5,800 pounds of thrust. That kind of sustained burn emulates typical requirements for a lander touchdown or a deep-space burn that could set a spacecraft on course from the Moon to Mars.show more

This video shows a static fire test of the... Archimedes rocket engine, developed by Rocket Lab. Archimedes uses liquid methane (LCH.) as fuel and liquid oxygen (LOX) as the oxidizer, a combination known as methalox. During combustion, these cryogenic propellants produce extremely high temperatures (over 3,000°C), hotter than lava. To survive this, the engine circulates cold fuel through its walls before burning it, a technique called regenerative cooling. Multiple Archimedes engines will power Rocket Lab's upcoming Neutron rocket, which is being built to launch satellites and cargo to orbit with lower cost and higher reliability. Rocket Lab is best known for its Electron rocket and is now expanding into larger, reusable launch vehicles with Neutron.show more

🚨 BIG: 🇮🇳 India's next defence breakthrough could be... powered by this homegrown engine Hyderabad-based Paninian India has unveiled the Yantur 4.5 kN turbofan engine programme, claiming it to be India's first privately developed compact turbofan engine in its class. The indigenous engine is being developed to power the company's SVAYATT-L1 long-range cruise missile and could also support future collaborative combat drones through higher-thrust variants. The programme has completed its conceptual and detailed design phases and is now progressing toward subsystem testing, validation and full engine certification, with the company aiming to strengthen India's indigenous defence propulsion capabilities.show more

🚨 NASA JUST TESTED A THRUSTER POWERFUL ENOUGH FOR... HUMAN MISSIONS TO MARS. Engineers have successfully fired a next-generation electric propulsion system that hit a new U.S. record of 120 kilowatts roughly 25 times more powerful than the thrusters currently flying on the Psyche spacecraft. Instead of using xenon gas like traditional ion engines, this experimental design runs on lithium metal vapor. The result? Dramatically higher efficiency and thrust while using up to 90% less fuel than chemical rockets. Why this matters: Electric propulsion doesn’t blast off like a rocket it provides gentle, continuous acceleration over months or years. That means spacecraft can reach much higher final speeds with far less propellant, making long-duration human missions to Mars far more practical. The deeper implication is staggering: We may finally be moving beyond the chemical rocket era. Future Mars ships could accelerate steadily for half the journey, flip around, and decelerate for the other half cutting travel time while carrying more crew and cargo. This is the kind of propulsion technology that turns the Solar System into humanity’s backyard. What happens when we have reliable megawatt-class electric thrusters flying to Mars?

🚨 A FORMER NASA ENGINEER CLAIMS HE’S DISCOVERED A... “NEW FORCE” THAT CAN OVERCOME EARTH’S GRAVITY WITHOUT ANY PROPELLANT. Charles Buhler, who spent years leading NASA’s Electrostatics and Surface Physics Laboratory at Kennedy Space Center, says his private company Exodus Propulsion Technologies has found a way to generate thrust using only electric fields. In vacuum chamber tests, their device reportedly produced enough force to counteract Earth’s gravity a claim that would completely rewrite the rules of propulsion. Why this matters: For over a century, every rocket we’ve ever launched has had to carry massive amounts of fuel. If this “New Force” is real, spacecraft could one day maneuver indefinitely without expelling mass potentially making deep space travel, satellite station-keeping, and even atmospheric flight dramatically cheaper and more efficient. The deeper implication is staggering: We may be looking at the first real breakthrough in propellantless propulsion since the invention of the rocket. If verified, this wouldn’t just change space travel it could reshape how we think about energy, momentum, and the fundamental laws of physics. Of course, extraordinary claims require extraordinary evidence. As of now, the work is still awaiting independent replication by outside laboratories. But if this holds up… What changes first space travel, energy production, or something we haven’t even imagined yet? Follow for more frontier physics and emerging technologies.show more

We just installed some CNC machines at the Engine... and Stage integration facility at Astrobase Space. Action >> Hype. The objective is to reach a stage where we can produce 50 FFSC rocket engines annually with 80 Tonne thrust each. This capacity plus Reusability allows Astrobase to deliver 200-500 tonnes annually to the orbits. With that, India will be able to sustain enough number of Sats in the space assuming standard rate of replenishment.show more

GE9X Water Ingestion Test - Proving the World's Largest... Jet Engine Can Survive Extreme Rain The General Electric GE9X, built for the Boeing 777X, must pass brutal certification tests before entering service. One of the toughest is the water ingestion test. What Is the Water Ingestion Test? This test checks if the engine can continue operating safely during extremely heavy rain. During the test: Large amounts of water are sprayed directly into the engine intake The engine runs at high power Engineers monitor performance and stability How the Test Is Performed In a specialized test facility: Water nozzles simulate intense rainfall Thousands of liters of water are injected into the airflow The engine operates at different thrust levels Sensors monitor: Combustion stability Compressor performance Temperature and pressure changes What Engineers Are Checking The engine must prove that: No flameout occurs No compressor stall happens Thrust remains stable Internal components are not damaged Even with massive water flow, the engine must keep running smoothly.show more

The Soviet Buran program developed reusable orbital spacecraft comparable... to the U.S. Space Shuttle, but with far more advanced automation. Its lone 1988 mission showcased a fully unmanned launch, orbit, and autonomous landing—an unprecedented achievement at the time. Lifted by the Energia rocket rather than onboard engines, the orbiter relied on sophisticated avionics and a unique engine-less design. Despite its technical success, the Buran program was canceled after the Cold War, and the only flown orbiter was later destroyed in a 2002 hangar collapse.show more
