Elon Musk on how far Raptor 4 could go:
“It is so tempting to make a 500 ton thrust Raptor 4 in place of the 250 ton Raptor 3 for the outer ring of the Starship booster”
Just look at the progression:
Raptor 1 → 185 t
Raptor 2 → ~230 t
Raptor 3 → 250 t (230t reliably)
Raptor 4 → Elon is already thinking about 500 t
That’s double the thrust of Raptor 3 from the outer booster engines
SpaceX keeps pushing rocket propulsion into completely absurd territory
SpaceX will attempt to catch both the Super Heavy booster and Starship on the upcoming flight.
If both are successful, it will mark the first time that all parts of an orbital rocket return to Earth intact.
This is the critical breakthrough needed to make life multiplanetary.
More than a dozen flight tests and years of development, with countless hours worked by SpaceX engineers and technicians, all come down to this: the first orbital Starship launch carrying advanced Starlink satellites bound for space.

Standing by Elon Musk was never about agreeing with every decision or expecting an easy road.
It’s about recognizing someone willing to take extraordinary risks to build a future most people can barely imagine.
Through the criticism, the setbacks, the victories, and everything in between, my support doesn’t disappear when the narrative changes.
I believed in the mission when it was difficult. I believe in it now.
Through thick and thin. 🚀

Astrobase website animation explicitly breaks down the key architectural flow paths that define a true full-flow staged combustion cycle:
Dual Preburners
It highlights the separate fuel-rich and oxidizer-rich preburners working simultaneously.
Independent Turbines
The graphic traces how these separate preburners feed into distinct, dual turbine drives to optimally power the propellant pumps.
100% Exhaust Routing
It shows how all of the gasified preburner exhaust is funneled directly into the main combustion chamber, eliminating propellant waste and maximizing thermal and propulsive efficiency.
If your plan to protect Americans from AI is to ban American development while China keeps building, you should be nowhere near policy.
You cannot legislate away the technology. You can only decide how much of it gets built here and whose rules the rest of the world follows.
Calling a ban a safety plan, without saying who loses their job, their savings, their edge when American companies fall behind, is not protection. It is surrender on a delay.
If China builds the future anyway, who exactly did you protect?

Far out in the uncharted backwaters of the unfashionable end of the western spiral arm of the Galaxy lies a small unregarded yellow sun. Orbiting this at a distance of roughly ninety-two million miles is an utterly insignificant little blue-green planet whose ape-descended life forms are so amazingly primitive that they still think digital watches are a pretty neat idea.
This planet has-or rather had-a problem, which was this: most of the people living on it were unhappy for pretty much all of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movement of small green pieces of paper, which was odd because on the whole it wasn’t the small green pieces of paper that were unhappy.
And so the problem remained; lots of the people were mean, and most of them were miserable, even the ones with digital watches. Many were increasingly of the opinion that they’d all made a big mistake in coming down from the trees in the first place. And some said that even the trees had been a bad move, and that no one should ever have left the oceans.
And then, one Thursday, nearly two thousand years after one man had been nailed to a tree for saying how great it would be to be nice to people for a change, a girl sitting on her own in a small café in Rickmansworth suddenly realized what it was that had been going wrong all this time, and she finally knew how the world could be made a good and happy place. This time it was right, it would work, and no one would have to get nailed to anything.
Sadly, however, before she could get to a phone to tell anyone about it, a terribly stupid catastrophe occurred, and the idea was lost forever.
This is not her story. But it is the story of that terrible, stupid catastrophe and some of its consequences. It is also the story of a book, a book called The Hitchhiker’s Guide to the Galaxy-not an Earth book, never published on Earth, and until the terrible catastrophe occurred, never seen or even heard of by any Earthman.

SpaceX is currently targeting Friday, November 13th for Starship's 15th flight, according to SpaceX's VP of launch, @TurkeyBeaver.
This flight is expected to include the first-ever Starship catch 🚀
