SpaceX tried to fly. It didn\u2019t.<\/p>\n
The thirteenth integrated test flight of Starship ended before it really began. Automated systems hit the brakes right at T-zero. Specifically, the abort happened at about 6:45 p.m. EDT. This was on Pad 2 at SpaceX\u2019s Starbase complex in Boca Chica, Texas. The vehicle sat upright on the launch mount. Intact. But cold.<\/p>\n
Dan Huot, a SpaceX spokesperson, explained the sequence during the live stream. “We got all down to start-up, triggered hold on booster,” he said. The engines were just igniting. The system shut them down immediately. No launch. Not today.<\/p>\n
So what went wrong? Elon Musk gave the answer shortly after via social media. Some Raptor engines simply didn’t start. Not all of them. But enough to trigger a safety hold. He called it a “failed start” of some engines.<\/p>\n
The fix involves hardware swaps. SpaceX plans to remove and replace two Raptor engines. They need confidence for the next try. When will that be? Most likely early next week. They have to drain the propellant first, inspect, and reinstall.<\/p>\n
\n“Two Raptor engines will be removed and replaced to be confident of a good flight,” Musk said.<\/p>\n<\/blockquote>\n
Flight 13 is essentially a do-over of a familiar path, but with new goals. It mimics the profile of Flight 12, which also started with a scrub. That previous flight was the first for the V3 hardware. This time, both the Super Heavy booster and the Starship upper stage are V3 iterations. They are bigger. Improved. More robust.<\/p>\n
The plan remained unchanged despite the delay. After lifting off, the Super Heavy booster separates. It is supposed to fly back. Not to the tower this time. The target is a pinpoint splashdown in the Gulf Of Mexico. It failed that specific maneuver during Flight 12, tumbling instead. Flight 13 needs to nail it.<\/p>\n
Meanwhile, Starship keeps climbing. It goes suborbital. It does not orbit the Earth yet. But it goes high. Once in space, the spacecraft depays twenty Starlink V3 satellites.<\/p>\n
Here is the strange part: those satellites are doomed.<\/p>\n
They survive about twenty minutes. Then they fall back through the atmosphere and burn up. But those twenty minutes matter. They serve as cameras. Specifically, they are meant to snap pictures of Starship’s heat shield as it faces reentry stress. They send that data down to Earth via the existing Starlink network. A sacrificial payload for data collection.<\/p>\n
After the satellite drop, Starship tries something bold. It attempts an in-space restart. One of its six core Raptor engines needs to ignite again for a short burn. This maneuver was scrapped on Flight 12 after a premature engine shutdown earlier in that test. Now, they are back at it.<\/p>\n
If successful, Starship continues its journey for an hour. It splashes down in the Indian Ocean, north of Australia.<\/p>\n
Why Starship Matters for NASA Artemis and Commercial Orbit Access<\/h3>\n
Why the hurry? Why the pressure on rapid turnaround?<\/p>\n
Falcon 9 has dominated SpaceX’s roster for years. It works. But Starship is the successor. Designed to carry one hundred metric tons to low Earth orbit, it dwarfs the Falcon 9 capacity. It allows SpaceX to launch massive constellations of Starlink satellites in a single flight. Efficiency scales up.<\/p>\n
But the clock isn’t just ticking for Starlink profits. NASA is waiting.<\/p>\n
The Artemis program hinges on Starship’s success. NASA wants to land astronauts on the Moon as early as 2028. That is the target date for Artemis IV. It requires a lunar-land variant of Starship. Not the version in Texas today. A derivative. But the core vehicle must prove it can reach orbit, separate, and return safely first.<\/p>\n
The requirement isn’t a one-time success. It’s a sustained capability. Artemis IV needs multiple launches in rapid succession to fuel up the lunar lander in Earth orbit. It requires propellant depots and reliable transport. SpaceX needs to show it can fly these beasts repeatedly. Without rapid reusability, the Moon mission falls apart.<\/p>\n
There is competition, too. NASA funded Blue Origin for a second lunar lander contract. A watchdog report in March highlighted that SpaceX is already lagging behind NASA’s aggressive timeline. The agency doesn’t want all its eggs in one basket.<\/p>\n
Artemis III is supposed to launch before the end of 2025. That is a test flight in low-Earth orbit. It involves docking Starship with Orion. If Starship can’t reliably reach orbit by then, the entire crewed Moon return is in jeopardy.<\/p>\n
That is the stakes of a scrubbed engine start in Texas.<\/p>\n
It\u2019s not just a failed test. It\u2019s a delay in a geopolitical race. And maybe just another Tuesday in rocket science. The teams go back to the pad. They swap two engines. They try again.<\/p>\n
Do we get orbit this time? Nobody knows yet.<\/p>\n","protected":false},"excerpt":{"rendered":"
