SpaceX’s preparations for Starship Flight 13 hit an unexpected setback after the vehicle triggered an abort during testing on the launch pad.In this video, we break down what happened, what the abort…
The flight computer, it detected that insufficient thrust right at ignition.
So the automatic abort triggered the exact moment the water deluge system activated.
You have this massive 11 million pound machine just sitting on the pad, fully fueled, and it shuts itself down at the absolute last millisecond.
It leaves you looking at this and wondering if they're just dealing with normal testing friction or if they have a fundamental engine problem.
And that's a problem that threatens an entire space industry that has basically tied its future to this exact rocket succeeding.
And if you look at the mechanics of that T-Zero abort, it shows you exactly how tight the operational margins actually are.
The flight computer has to manage just an impossible amount of data in those final milliseconds.
For the Super Heavy booster, the acceptable limit is a maximum of three failed engines on startup.
They have 33 Raptor engines clustered at the base, and they're all trying to light simultaneously.
To understand why three is that hard limit, you'd have to look at the physics of the vehicle.
Like I said, the whole stack weighs roughly 11 million pounds when it's fully loaded with liquid oxygen and liquid methane.
So those 33 engines combined, they produce around 16 million pounds of thrust.
If you lose one or two engines, you are losing a fraction of your total thrust, sure, but your thrust-to-weight ratio remains above one.
Exactly.
