ELON MUSK: "Raptor 3 engine is very advanced engine, by far the best rocket engine ever made. On liftoff, Starship is generating over 100 gigawatts of power. It's 20% of US, while not exploding. There's thousands of ways it could explode and only one way that it doesn't."

Elon Musk: Raptor 3 is kind of alien technology “Even industry experts, when we showed a picture of the Raptor 3, said, ‘That engine is not complete’” “Well, here’s the engine - not complete - firing at a level of efficiency that has never been achieved before” Raptor 3 is a massive leap forward in rocket engine design • No base heat shield required, saving huge mass and improving reliability • Fuel leaks are no longer catastrophic, they safely burn off in open plasma • Dramatically higher payload capacity and efficiency • Simpler design with fewer parts, but far more capability • Secondary fluid systems and electronics are integrated directly into the engine structure

Elon Musk: Raptor 3 is alien technology. “Raptor 3 is a massive increase in payload capability, in engine efficiency, and in reliability. This is really a revolutionary engine. Raptor 3 is really kind of an alien technology rocket engine. Even industry experts, when we showed a picture of the Raptor 3, said, that engine is not complete. Then we said, here's the engine, not complete, firing at a level of efficiency that has never been achieved before. That is one clean engine. In order to make the engine like that, we had to simplify so many parts of the design, incorporate secondary fluid circuits and electronics in the structure of the engine itself so everything is contained and protected. It is a marvel of engineering, frankly.” From: SpaceX Update, May 27, 2025

Elon Musk on Raptor 3 Engine: "Raptor 3 is designed to require no basic heat shield, saving a lot of mass on the bottom and actually improving reliability, so that if there is, for example, a small fuel leak from the Raptor engine, it will simply leak into the existing flaming plasma and not really matter, whereas a fuel leak when the engines are contained in a box is a very scary thing indeed. It will be a massive increase in payload capability, in engine efficiency and in reliability. So this is really a revolutionary engine. Raptor 3 is really, I'd say, kind of alien technology, rocket engine. So in order to make the engine like that, we had to simplify so many parts of the design, incorporate secondary fluid circuits and electronics in the structure of the engine itself, so everything is contained and protected. It is a marvel of engineering."

Yes, LANDSPACE is going for full-flow staged combustion cycle methalox engine & fully reusable 2-stage rocket, confirms the CEO ZHANG Changwu in an interview Engine will be 200t-thrust Raptor alike. Rocket will obviously be Starship-like. The goal is to achieve it around 2030.

The most important upgrade to Starship isn't a new Raptor engine or a bigger booster. It's hidden beneath the launch pad. SpaceX is quietly changing how the world's largest rocket is fueled, and it could be the breakthrough that makes rapid reusability possible. #SpaceX #Starship #RocketScience #Cryogenics #Starbase

Flashback to July 2022: Elon Musk showing Everyday Astronaut the massive leap from messy Raptor 1 (‘Christmas tree’ vibes 😂) to clean Raptor 2 – 230 tons thrust at 300 bar, tons of parts deleted! Fast-forward to 2026: We’re already on Raptor 3 – 280+ tons thrust, even simpler design, no external pipes, in production (100+ built!), testing like crazy, set for Starship V3 flights soon. Insane progress in ~3.5 years!

Raptor 3 is a beast! Testing a Raptor 3 engine doing what it would do during a Starship V3 launch. SpaceX is running different versions of this test to make sure the three center engines can handle all the conditions they’ll face on the way up.

🇺🇸 SpaceX just flew an engine so advanced, only 2 other organizations in history ever built one. The Soviet Union tried, the US barely demoed it, but SpaceX actually flew it. Raptor 3 hits 350 bar chamber pressure, a world record, and shaved 10+ tons by eliminating heat shields, fire suppression systems, and basically anything that wasn't absolutely necessary. Pure confidence in engineering. "Raptor 3 is engineering art." Definitely. Source: AstroMind Hub YT, Elon Musk, SpaceX

STARSHIP V4: 42 ENGINES – THE PROPHECY FULFILLED, AS FORETOLD IN THE GUIDE TO THE GALAXY Starship V4 is leveling up with 3 additional vacuum Raptor engines on the ship, bringing the total stack count to the ultimate answer: 42. This isn’t just a nod to Hitchhiker’s Guide—it’s a massive thrust boost for deeper space missions, better efficiency, and the rapid reusability needed to build a Mars city. Here’s Elon’s direct quote: “The Starship V4 ship will have 3 more vacuum engines, making the total stack engine count 42, as foretold in the prophecy” This upgrade unlocks: •Insane thrust — Pushing toward 10,000+ tons total, enabling heavier payloads for Moon landings and Mars cargo fleets. •Enhanced vacuum performance — More optimized engines for orbital and interplanetary maneuvers, reducing refueling needs. •Faster iterations — V4 builds on V3’s reliability, closing in on airline-like launch cadence for multiplanetary goals. •Prophecy power — 42 isn’t random—it’s the cosmic key to life, the universe, and everything… including humanity’s future off-Earth. Every engine added edges us closer to boots on Mars. The ultimate answer is clear: Starship is the way.

We fired a really cool rocket engine - and broke some records while we were at it. 🔥This Rotating Detonation Rocket Engine produced more than 4,000 pounds of thrust, and included a 300-second continuous burn, which is believed to have set the record for longest duration hot firing of an RDRE engine to date. Watch it fire:

Why doesn't SpaceX just use the Raptor engines to brake before hitting the atmosphere?" It's the most common question under every Starship reentry stream. It sounds like a common-sense solution to save the heat shield tiles. But trying to slow down using fuel instead of atmospheric drag introduces a brutal physics trap. To completely cancel out orbital velocity using raw engine thrust, Starship would need to carry an impossible amount of weight. Here is exactly why the Rocket Equation makes a "cool reentry" mathematically impossible: 👇#spacex #starship #reentry #raptor

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

SpaceX’s Raptor 3 engine is sublime engineering • No basic heat shield needed → saves mass and dramatically boosts reliability • Small fuel leaks aren’t dangerous — they simply burn off safely in the open plasma • Major improvements in payload capacity, efficiency, and overall reliability • Radically simplified design with deeply integrated electronics and fluid systems • So clean and minimalist that even propulsion experts initially thought it looked “unfinished”
