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....

This is the recent hotfire test of Astra's most powerful Rocket 4 first stage engine. The quick green flash comes from a special compound called triethylborane (TEB). It's pyrophoric - meaning it spontaneously ignites the moment it touches air. That super-hot green flame then lights the main propellants: kerosene and liquid oxygen. Once ignited, the engine unleashes a roaring orange plume and huge clouds of smoke. These ground tests prove the engine is ready for flight - checking thrust, stability, and performance before it ever leaves the pad. Credits: astraspace

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.

ELON: STARSHIP MAKES SATURN V LOOK LIKE A PROTOTYPE Elon said the Starship program is “thousands of times more capable” than the Saturn V, the rocket that carried humans to the Moon. This isn’t trashing Apollo, it’s pointing out the leap: full reusability, massive payloads, rapid launch cadence, and radically lower cost per ton to orbit. Saturn V was a heroic one-off era, while Starship is designed as industrial infrastructure that flies over and over again. Moon landings were history, mass access to space is the endgame. “A Starship is 2.5 times the thrust of a Saturn V. Saturn V was the largest rocket to ever reach orbit, and this has 2.5 times more power than that. They’re meant to be reusable… we’re talking about something that ultimately as a system, is thousands of times more capable than the Saturn V program.” Source: ELON CLIPS, Elon Musk

The United Launch Alliance Atlas V has arrived on the launch pad for its midnight ride to low Earth orbit tonight, continuing the rocket's workhorse service in helping deploy the Amazon Leo constellation. ULA's Atlas has launched more than half of the network's satellites so far. ULA is proceeding with a continuous roll-and-launch in a single-day countdown, part of our efforts to increase launch cadence for our Amazon Leo customer. This effort reduces the amount of time the rocket spends at the pad, enabling launch to occur sooner. Liftoff time is 12:24 a.m. EDT (0424 UTC). // Amazon Leo

🚨BREAKING: HEZBOLLAH USE LARGE MISSILE FOR FIRST TIME THIS WAR The explosion below is suspected to be ''Burkan" Missile from Hezbollah. This would be the first time that Hezbollah has used this weapon in this war, marking an escalatory step due to its increased payload. The Burkan, also known as “The Volcano”, has a range of 500-2,000 meters and can carry explosive warheads that weigh hundreds of kilograms. The video below shows the rocket being used in a different conflict. Is this a warning to Israel, or is it indicating an intention to escalate? Source: Yedioth Newspaper

🇮🇱🇮🇷 The massive explosion in Beit Shemesh was at the Tomer Company, Israel's government defense firm that builds the rocket engines for Arrow 2 and Arrow 3 missile interceptors. The systems Israel uses to shoot down Iranian ballistic missiles. Here's why the "controlled explosion" explanation doesn't hold up: Controlled detonations require advance public notification. There was none. Emergency services were scrambled immediately to respond. You don't scramble emergency services to something that was planned. And the scale of the blast is consistent with one thing: rocket motor propellant or solid fuel igniting unexpectedly. Which makes complete sense for a facility that manufactures rocket propulsion systems. The most likely explanation: an accident during testing or production. But the timing is worth sitting with. Iran just escalated for the first time on its own terms, not in response to U.S. action, but initiating. A more emboldened Iran than the one that entered this ceasefire. An accident at Israel's most critical missile defense facility is the probable answer. Sabotage, at exactly this moment, at exactly this target, cannot be fully ruled out.

🚨 NASA just tested an experimental engine that could dramatically cut travel time to Mars. This isn’t a normal rocket. It’s a nuclear-powered ion engine capable of producing plasma hotter than 2,800°C while firing electromagnetic lithium exhaust through space. NASA says the new thruster is already 25 TIMES more powerful than current ion engines. And future versions could reach megawatt-level power. Why this matters: The faster astronauts reach Mars… the less time they spend exposed to deep-space radiation, muscle loss, and isolation. This may be one of the first real steps toward practical human missions to the Red Planet. The space age is starting to look very different. Follow for more future technology and space breakthroughs.

This week, the IDF Artillery Corps conducted its first operational shelling with the new Ro'em self-propelled howitzer, in support of ground forces operating in southern Lebanon. The 282nd Artillery Regiment used the Ro'em, also known as the SIGMA 155, to shell Hezbollah rocket and anti-tank launch sites. The military says the shelling was "deemed successful and yielded achievements." The IDF says the Ro'em brings "groundbreaking capabilities to the battlefield," including increased fire-rate, longer firing ranges, and better mobility than existing howitzers. The Ro'em will enter service gradually through the conversion of artillery battalions that currently operate the aging M109 howitzer.

An airplane radial engine is a powerful internal combustion engine where cylinders are arranged in a circle around a central crankshaft, resembling the spokes of a wheel. Renowned for their exceptional power-to-weight ratio and reliable air cooling, they were the dominant powerhouses of early aviation and World War II. An aeroplane radial engine operates by converting fuel into mechanical rotation through a unique circular piston arrangement. The cylinders are positioned in a circle around a central crankcase, resembling the spokes of a wheel. Inside the hub, only one "master" connecting rod attaches directly to the crankshaft, while all other rods anchor to the base of that master rod. As fuel ignites inside the cylinders, the pistons fire in a specific "skip-one" sequence-such as 1, 3, 5, 7, 9, 2, 4, 6, 8-to distribute power evenly around the hub. This sequential pushing motion turns the master rod assembly, which rotates the crankshaft and spins the aircraft propeller. Finally, because the cylinders face forward into the oncoming wind, the engine cools itself naturally using direct airflow instead of heavy liquid radiators.

❗️❗️❗️ For the first time in a long period, the Russian army is retreating in the Zaporizhzhia and Dnipro directions 🇷🇺 The Russian spring offensive campaign, which the occupiers had been preparing for over the past months, has collapsed due to colossal losses and Ukraine’s technological superiority on the battlefield. 📍 In certain directions, the Ukrainian Armed Forces are already advancing. The Russian Federation continues to strike cities using multiple launch rocket systems (MLRS), however Ukraine is destroying the occupiers’ rear logistics with increasing effectiveness. 📍 It is for this reason that Russia will intensify terror against major cities and the civilian population in order to exert pressure during negotiations….

🚨🇺🇸 ANOTHER CLEAN RETURN FOR SPACEX AS FALCON HAS A FLAWLESS TOUCHDOWN SpaceX nailed it again. Falcon 9 booster successfully touched down at Landing Zone 4 moments ago after launching [payload/mission details if known, otherwise: its latest mission from Cape Canaveral. The booster, fresh off the pad, executed a textbook return to LZ 4 on Florida's Space Coast, legs deployed, engines relit, and a perfect vertical touchdown. This marks yet another precise landing for the reusable rocket program that's redefined spaceflight. With boosters now routinely flying multiple missions, SpaceX continues to drive down launch costs and push rapid reusability closer to reality. Falcon 9 landing at LZ-4 is the kind of routine that used to be impossible. Now it's just a Friday. Yet it still gets me every time. Source: SpaceX, NSF - NASASpaceflight.com
