Title: SpaceX Has Finally Figured Out Why Starship Exploded, And The Reason Is Utterly Embarrassing
- SpaceX’s Starship experienced a catastrophic explosion during its seventh launch attempt, resulting from a failure in the fuel line due to vibrations.
- The explosion occurred over the Turks and Caicos islands, leading to debris scattering over the area.
- The fuel leak ignited two minutes after the upper stage’s engines were ignited, overwhelming the rocket’s venting capacity and compromising the engines.
- A loss of communication with ground control occurred as the engines shut down, leading to the rocket’s self-destruction sequence.
- The incident highlights significant operational failures, as engine shutdowns should not cause communication loss, indicating a lack of redundancy in systems.
- SpaceX’s pre-flight checks failed to identify potential leaks, suggesting inadequate safety measures or poor execution of checks.
- In contrast, NASA’s Saturn V rocket had a flawless launch record over its operational lifespan, showcasing superior reliability compared to Starship.
- Starship’s design has been criticized for overestimating engine thrust capabilities, limiting its payload capacity to 40-50 tons, which is less than the Saturn V.
- The cost per kilogram to launch with Starship is comparable to that of the Saturn V, undermining its intended economic advantages.
- The overall failure of Starship raises concerns about the efficiency and safety of SpaceX’s approach to space exploration, contrasting sharply with historical successes in the field.
Thank you for sparing us from the clickbait title

These points are really silly. Two engines exploded causing the ship to tumble. I’m not sure what they think additional communications redundancy would help with at that point.
And how do you indefiy a fuel leak on the ground that hasn’t happened yet? It was caused by vibrations at a resonant frequency that is only reached at a certain fuel level?
- Starship’s design has been criticized for overestimating engine thrust capabilities, limiting its payload capacity to 40-50 tons, which is less than the Saturn V.
Who said that? That’s really silly. And isn’t that payload with full reusability?
Space is hard, it’s literally rocket science. The embarrassing thing is it failed in the same way twice. But finding these resonance issues that only pop up in specific fuel states, makes sense it’s hard to pin down. I think they’ll need to characterize their vib spectrum as fuel burns down, then analyze the harmonics of the hardware and make sure they don’t couple. It isn’t easy, but they should be able to.
Edit: thanks for the summary, I just disagree with the article.
Also starship hasn’t started its operational lifespan. These are test articles still. They should absolutely be treating them with respect and due diligence since they are launching, but this is just highly public testing on a reusable rocket. Success not guaranteed and that’s why they aren’t flying real payloads (even of their own).
Also, pretty sure Apollo 1 was a great example of Saturn rockets not being flawless.
No changes were made to the Saturn family of rockets due to the Apollo 1 fire.
The command pod was changed not use a pure oxygen environment, but that is an entirely separate vehicle to the rocket itself.
What does Apollo 1 have to do with the reliability of the Saturn rockets…?
"A loss of communication with ground control occurred as the engines shut down, leading to the rocket’s self-destruction sequence.

For the communication redundancy part: This is just my interpretation of what I’m reading and it could be 100% wrong.
The communications need a redundant power supply/ connection not associated with the engine. Because they didn’t have the communication connection and the engines were on fire the self destruct was initiated. Where if they had communications maybe they could have done something else? Turn off fuel, changed location of impact, changed location of self destruct to not be where it was.
I could be wrong, Iam in fact not a rocket scientist
That’s also my interpretation. Which tracks with Musk companies, which tend to cut corners by cutting out redundancies.
At least with the Teslas, they also fail to isolate systems for cost cutting, and everything tied into the same bus causes a weird cascade with completely unrelated components when there are failures. If he’s forcing the same design philosophy with the rockets, that’s a completely moronic move.
Also, I don’t think the engines provide electrical power, that’d be from the batteries.
Edit: yeah, they use helium to spin the turbo pumps, so no electrical generator/motor on raptor.
Two engines exploded, blowing the back of the ship up, causing the ship to tumble, which lead to loss of communication a few minutes later. Abort was absolutely the right call. Saying communications need to be better is like saying you need a better bandaid for your stump of an arm after you blew it off with a grenade.
The communications failed because the ship was spinning faster and faster, and eventually the antenna tracking couldn’t keep up.
As soon as the engines exploded, the mission was dead, so the best thing is to abort, which is what they did.

Rocket-hands awarded post.
They say space is hard…
So you know that it’s ok…
That is an amazing piece of editorial bullshit.
As someone who hadn’t seen elsewhere what caused the failures it highlighted both the fires that took place, the communication failure and the self destruct. The title is shit but what else were you looking for?
This guy’s writing is horrid. At least we got the facts from the investigation.
At least we got the facts from the investigation
Not really. The only relevant bit was “vibrations caused a failure of a fuel line in the aft section of the upper stage” which had been widely reported elsewhere.
It’s AI slop
God this title is so dumb.
Yes, fuck Elon Musk. That doesn’t mean Starship isn’t still the most exciting topic in rocketry/spaceflight, and 100x more ambitious than what any other rocket manufacturer is attempting.
The Starship development cycle is hardware-rich, they have a literal conveyor belt full of rockets in various stages of completion for testing.
Their immediate goal isn’t to go to orbit, they could have done that a long time ago. They’re simultaneously testing hundreds of little to big changes to the vehicles with every launch. Stuff will go wrong along the way.
Yes, because Elon Musk is such an asshole people can’t seem to help themselves from talking shit, even when it’s misguided.
They talk about the safety record of Saturn rockets without mentioning that using those isn’t currently possible and then talk about cost per ton of falcon without acknowledging the same design process that created that rocket is being used to make this one. Falcon also had a fair number of explosions before the kinks were worked out and now it’s launching so often that no other company or nation is even close to the same cadence.
And it sucks! Because I’m interested in space, and SpaceX has done very impressive things, and it’s owned by this fucking jerk.
Well said.
Then Musk needs to stop hailing Starship as the next great thing. He doesn’t get to talk about how awesome it is, then, when it goes boom, say “oopsie, still testing, and you’re dumb for expecting otherwise”.
They’re simultaneously testing hundreds of little to big changes to the vehicles with every launch. Stuff will go wrong along the way.
If that results in their rockets exploding, perhaps they should not be allowed to do this? That’s not how science is performed.
Exploding rockets are not exactly friendly to nature or people.

Starship is not a science project. No scientific breakthroughs are made or expected. It is an engineering project. And this is exactly how that is performed.
Also, how many people crashed how many planes before the Wright brothers managed to achieve powered flight ?
Put some Musk as ballast
It’s because Elon has a tiny red button for self destruction and he keeps pressing it every time, isn’t it?
There’s a simple solution. Put the button in the starship
