I have also always thought that not having any sort of flame mitigation was a huge mistake from the start. I thought it was sort of evident after the short static fires that bad things would happen without something in place. |

D politicians would love to make political hay over this but I don't see much of that happening. NASA has awarded over $3B in contracts to SpaceX that rely on Starship becoming not just operational, but man rated, as it is their chosen delivery method for putting the next people on the moon. SLS will get them there. Starship takes them down to the surface and back up to orbit after. Not just that, but NASA, NSA, NRO, CIA, DoD, NSF, etc., are all salivating at the enormous diameter, volume and payload the booster can deliver to orbit. Same goes for commercial launch customers that have politicians in their hip pocket. No, entrenched bureaucrats who wield the real levers of power and control in .gov REALLY want this to be successful. That's my take anyway. |

Basically it's what Disneyworld did later on with the concrete "Utilitadors" network of tunnels, and built foundations for all the attractions at mostly ground level, then bought in an additional 12' of soil to cover it all and make the park's public street level. I assume in that flat sandy area so close to the ocean, the geology is similar in Boca Chica. So I'd guess that the lack of a trench and water deluge system, and risk of FOD, and even acoustic shaking or resonance damage to Superheavy it created, was calculated against the massive earthworks needed to raise the level. So the expense and time for what might be destroyed by a RUD right on the pad, at a site that has a limited use-time, and EPA, Army COE, and whatever TX submissions, reviews, and approval would be needed, not just for the diverter & deluge system, but a bajillion cubic yards of dirt was in the balance. I imagine that amount of dirt getting trucked in would get a lot of hairy eyeball from bureaucratic enviroweenies. It could be cut corners, or simply just not worth it, not just in sunk-costs time and expense, but in future losses against testing and upgrades/changes. Just my armchair opinion, but the only loss from not having a more sophisticated pad is if the failures turn out to be 100% FOD and/or noise and vibration, and nothing else could be learned, and it doesn't sufficiently advance the aggressive "Physical test & iteration" strategy. |

From ChatGPT:
Starship soared high into the sky, A shiny steel rocket, sleek and spry. Its engines roared with a fiery might, As it pierced the heavens, a dazzling sight. The countdown ticked, the tension rose, But Starship knew just where to go. Through clouds and skies it cut a path, A mission of science, with no aftermath. But as it reached the pinnacle of space, Disaster struck, a fiery chase. Starship burst into a million parts, And scattered across the ground, broken hearts. But even in its catastrophic fall, Starship gave us lessons, new knowledge tall. For though it failed, it tried its best, And inspired us all, to reach for the crest. |

Maybe Sea Dragon water launches weren't such a dumb idea for a huge rocket.
Doesn't help the Mars launch piece though... Regardless - awesome event today. |

Given the damage to the launchpad and other support facilities - how far is Boca Chica still ahead of the Florida launch site?

In the long run I think confirming the Stage 0 flaws now will turn out to be worth any setback. And now Starship teams have a lot of real data to work with while Stage 0 gets revamped. |

Only the ship would be taking off from Mars or the moon, and with lower gravity and little or no atmosphere, it won't need that much thrust to get off the surface, but at the same time those conditions will cause debris to that is kicked up to fly a very long distance. They might need terrain or a berm between the landing pad and the habitats on Mars. On the moon, debris might even make a full orbit and hit surface structures from the opposite direction. |

View Quote Correct. More I think about it, the more I'm concerned about the initial soft landing on the moon. It will come down pretty gingerly with thrusters firing until it is settled. All that will kick up a lot of debris potentially damaging the engines or other components. Obvious and cool ass Buck Rogers solution would be to pre-stage a robotic Stage 0 on moons surface. It would land first, level itself, then unfold blast shield petals similar to an unfolding solar panel. Starship then lands and blasts off from this safe LZ. If they go this route, I want full credit for crazy idea. |

I can not think of a good way to integrate a flame trench with the existing launch mount. The water table is too high and they will probably need a pretty deep pool to obsorb the thrust. Repairing and retrofitting the launch mount would probably cost more than a complete redesign. The crane tower can be reused but it will have to be taller. Is an oilrig style launch platform the better option? The hight can be adjusted with buoyancy and you get a free source of coolant for your exhaust. |

I wonder if there are individual flight termination systems for booster and ship. Maybe they didn't separate on purpose.
