Elon Musk exposed: SpaceX's Raptor V3 Upgrade Could Be a Big Issue.Here's why...
SpaceX’s brand new Raptor 3 engine is here—and it’s a beast! More power, more performance, and a super sleek design that’s supposed to change the game for space travel. But... there’s a problem. Actually, two major ones.
Elon Musk himself says the startup sequence is so insanely complex, if even one thing goes slightly off... BOOM. You’ve got a multi-million-dollar fireworks.
And if you think fixing it is an option? Think again. SpaceX went all-in on a fully welded design. No bolts, no flanges—just one solid piece. Which is great for strength… but terrible for maintenance.
So we’re talking about an engine that’s hard to start... and even harder to repair. In today's Techmap episode, we’re diving deep into what SpaceX is really up against with Raptor 3 and whether these bold design choices could come back to bite them.
Will this next-gen engine take us to Mars, or blow up before liftoff? Let’s find out.

While Raptor 3's supposed to be more reliable than ever, there’s a catch (at least for now). And guess who confirmed it? None other than Elon Musk himself. In a recent post on X, he casually dropped a bombshell about the engine’s startup sequence: “Very complex startup sequence. Insane timing precision is needed to avoid blowing up the engine.”
Yeah… not exactly a confidence booster, right?
Turns out, getting Raptor 3 up and running is a bit like trying to perform open-heart surgery with chopsticks. Every move has to be timed just right, or the whole thing could blow, literally. It’s one of the most complex parts of the engine’s design, even more so than earlier versions.

Here’s how the whole startup dance goes down:
Step 1: Super chill before ignition
Before anything even starts, certain parts of the engine need to be cooled way down. Why? Because the fuel is so cold it could crack the metal if the engine’s too warm. Ice bath first, fire later.
Step 2: Spin up the beast
Next, the engine’s massive pumps have to kick in. These bad boys push liquid oxygen and methane into the engine, and they need to hit just the right speed. Too fast or too slow? That’s a problem.
Step 3: Light the mini flames
Before the main fire show starts, tiny burners (called preburners) need to ignite in a super-specific order. They power the pumps and get the main engine ready for liftoff.
