SpaceX Starship prototype ignites six engines, starts major brush fire
SpaceX has successfully ignited all six engines on its latest Starship prototype, taking a significant step towards ensuring that the upper stage will be ready for the rocket’s first orbital launch attempt.
Unfortunately, the same successful static fire of a Starship upper stage – potentially producing almost twice as much thrust as the booster of SpaceX’s Falcon 9 rocket – scattered superheated debris hundreds of meters away, igniting a major brush fire. It’s not the first major fire caused by Starship activities in South Texas, and it likely won’t be the last.
Starship S24 completed its first successful static fire on August 9th, igniting two Raptor engines. Several unsuccessful attempts to test more engines followed throughout the rest of the month, and SpaceX ultimately decided to replace one of Starship S24’s three Raptor Vacuum engines in early September before trying again. After workers installed the new engine and buttoned up Ship 24, the stars eventually aligned on September 8th.
Kicking off the test, SpaceX pumped several hundred tons of liquid oxygen (LOx) and a much smaller quantity of liquid methane (LCH4) fuel into Ship 24 in about 90 minutes, producing a crisp layer of frost wherever the cryogenic liquids touched the skin of the rocket’s uninsulated steel tanks. No frost formed on Starship’s upper methane tank, implying that SpaceX only loaded methane fuel into internal ‘header’ tanks meant to store propellant for landings. The hundreds of tons of liquid oxygen, then, were likely meant as ballast, reducing the maximum stress Starship could exert on the test stand holding it to the ground.
That potential stress is substantial. Outfitted with upgraded Raptor 2 engines, Starship S24 could have produced up to 1380 tons (~3M lbf) thrust when it ignited all six for the first time at 4:30 pm CDT. On top of smashing the record for most thrust produced during a Starbase rocket test, Ship 24’s engines burned for almost 8 seconds, making it one of the longest static fires ever performed on a Starship test stand.
Several brush fires were visible almost immediately after clouds of dust and steam cleared. More likely than not, the combination of the extreme force, heat, and burn duration likely obliterated the almost entirely unprotected concrete surface below Ship 24. Despite continuous evidence that all Starship static fire operations would be easier and safer with the systems, SpaceX still refuses to install serious water deluge or flame deflector systems at Starbase’s test stands and launch pads.
Instead, under its steel Starship test stands, SpaceX relies on a single middling deluge spray nozzle and high-temperature concrete (likely martyte) that probably wouldn’t pass muster for a rocket ten times less powerful than Starship. In multiple instances, Starships have shattered that feeble martyte layer, creating high-velocity ceramic shards that damage their undersides or Raptor engines, requiring repairs and creating risky situations. With essentially no attempt at all to tame the high-speed several-thousand-degree Raptor exhaust, static fire tests at Starbase thus almost always start small grass fires and cause minor damage, but those fires rarely spread.
Ship 24’s first six-engine test was not so lucky, although the Starship made it through seemingly unscathed. Most likely, eight long seconds of blast-furnace conditions melted the top layer of surrounding concrete and shot a hailstorm of tiny superheated globules in almost every direction. Indeed, in almost every direction there was something readily able to burn, a fire started. In several locations to the south and west, brush caught fire and began to burn unusually aggressively, quickly growing into walls of flames that sped across the terrain. To the east, debris even made it into a SpaceX dumpster, the contents of which easily caught fire and burned for hours.
Eventually, around 9pm CDT, firefighters were able to approach the safed launch pad and rocket, but the main fire had already spread south, out of reach. Instead, they started controlled burns near SpaceX’s roadblock, hoping to clear brush and prevent the fire (however unlikely) from proceeding towards SpaceX’s Starbase factory and Boca Chica Village homes and residents.
The nature of the estuary-like terrain and wetlands means that it’s very easy to stop fires at choke points, so the fire likely never posed any real threat to Boca Chica residents, SpaceX employees, or onlookers. It was also unlikely to damage SpaceX’s launch facilities or return to damage Starship S24 from the start, as both of are surrounded by a combination of concrete aprons, empty dirt fields, and a highway.
Still, the “brush” burned by the fire is a protected habitat located in a State Park and Wildlife Refuge. While fire is a natural and often necessary element of many habitats, including some of those in Boca Chica, this is the second major brush fire caused by Starship testing since 2019, which may be less than desirable. At a minimum, fighting fires around Starbase generally requires firefighters to walk or even drive on protected wetlands and salt flats, the impact of which could ultimately be as bad for wildlife and habitats as the fire itself.
SpaceX’s Federal Aviation Administration (FAA) Programmatic Environmental Assessment (PEA), which fully greenlit the company’s existing Starbase Texas facilities and launch plans earlier this year, only discusses fire [PDF] a handful of times. Repairing and preventing future damage to wetlands, however, comes up dozens of times and is the subject of numerous conditions SpaceX must meet before the FAA will grant Starship an orbital launch license.
Ultimately, given that the FAA approved that PEA in full awareness of a 2019 brush fire caused by Starhopper (an early Starship prototype) that may have been as bad or worse than 2022’s, there’s a chance that it will play a small role in the ongoing launch licensing process, but the odds of it being a showstopper are close to zero. Still, it would likely benefit SpaceX at least as much as the surrounding Boca Chica wilderness if it can implement changes that prevent major brush fires from becoming a regular ‘accidental’ occurrence.

SpaceX tells the FCC that Starship Flight 14 is going to orbit
SpaceX filed with the FCC for Starship Flight 14, its first true orbital launch attempt.
SpaceX has asked the Federal Communications Commission for permission to fly Starlink terminals during Starship’s fourteenth flight test, and the filing lays out a genuine trip to orbit, something the program has never attempted.
Every Starship flight so far, including Flight 13’s successful splashdown in the Indian Ocean on July 24, has flown a suborbital arc that ends with the ship reentering the atmosphere within the same hour it launches. The FCC paperwork describes a mission profile built around an actual orbital insertion instead.
The payload is the other half of the story. Flight 13 carried 20 production Starlink V3 satellites, but because that mission never reached orbit, the satellites reentered along with the ship rather than joining the constellation, something Teslarati covered in detail after SpaceX released footage shot from one of those satellites as it drifted away from Starship in space. Flight 14 is designed to close that gap. If the orbital insertion holds, the roughly 20 V3 satellites onboard would separate into an operational orbit and could eventually go into service, each one rated for about 1 terabit per second of downlink capacity by SpaceX’s own account.
SpaceX announces new Starbase for ‘thousands of Starship launches annually’
Elon Musk first flagged the orbital attempt during SpaceX’s August 4 earnings call, the company’s first as a public entity following its June IPO under the ticker SPCX. He also floated catching the ship with the Starbase tower on the same flight, an idea he walked back on August 20, saying the catch attempt would more likely come “in a few months,” as Teslarati reported at the time. Flight 14 will instead target a splashdown for the ship in the Indian Ocean, the same recovery method used since Flight 12.
Hardware has been catching up to the ambition. Booster 21 completed a full 33-engine static fire on August 28, and Ship 41 finished its own six-engine test the week before. An airspace briefing circulated to pilots on August 20 listed September 15 as the target date, later than the end of August window Musk mentioned on the earnings call, though SpaceX has not confirmed a launch date publicly and Starship schedules routinely slip while hardware and FAA paperwork line up.
The FCC filing itself does not guarantee a launch date. It covers communications authority, and not flight readiness, considering SpaceX still needs Ship 41 fully stacked and cleared by the FAA before Flight 14 can fly. But the filing is a real marker of intent and it puts a specific regulatory process behind what had so far only been Musk’s word on the earnings call.
Tesla is set to launch Cybercab on Thursday at an event in Austin, Texas, which will officially bring the company’s first steering wheel-less and pedal-less vehicle to a limited number of consumers for the first time.
The event, which is invite-only, is still thin on details: we’ll be there, and it seems the event will be held at Gigafactory Texas, but the launch of this vehicle truly relies on it being operational outside of the factory and on public roads.

Nevertheless, there are some big things to expect, and other things to temper expectations on. For what it’s worth, we believe this event could be perhaps the biggest indication that Tesla is ready to truly enter a new phase and chapter in its historic story.
Tesla Cybercab’s First Foray into the Public with Real-World Riders
Cybercab will likely hit the streets of Austin and the surrounding areas, likely in the established geofence that Tesla has expanded on for the past 14 months. Just yesterday, Tesla expanded it once again by 9 percent.
Tesla will put, for the first time, a vehicle without any manual controls on public roads, likely without any help from teleoperators. This is a truly groundbreaking development if it comes through in this fashion: it would be groundbreaking for Tesla to roll out a truly driverless ride-hailing vehicle.
Cybercab Has Already Been Unveiled
This is not an unveiling event. Cybercab has been released for nearly two years, as Tesla first showed it to the public on October 10, 2024.
FIRST LOOK: Tesla ‘Cybercab’ Robotaxi makes its global debut
While there is some small speculation that Tesla could release the Roadster at the event as a surprise, it seems more likely the focus will be on the Cybercab and the huge accomplishment that will come with releasing a vehicle with no manual controls.
There Will Be a Lot of Hype
What’s important to remember about the Cybercab event is that Tesla will continue to prioritize safety and the rollout will likely be slow, just as it has been with Robotaxi.
One of the biggest complaints about Robotaxi is vehicle population, and the fact that the wait for a ride, at least in some instances, has been longer than most want to admit.
It will take time for this project to truly scale. It will take time for Tesla to roll this out in a large fashion. The important thing to note is that they are doing it, and they’re doing it with a vehicle that is completely engineered and built internally. That’s something no other ride-hailing service can say.
Elon Musk recently restated a fact that still defines SpaceX’s origin story: if Falcon 1’s fourth launch had failed, the company would not exist. The comment answered a reminder that after three consecutive losses, SpaceX had money for only one more attempt.
On X, Peter Diamandis said that the present-day acknowledgement of SpaceX’s success does not discount the rough start the company had. “Almost nobody remembers that Elon’s first rocket failed three times, and there was money for exactly only one more attempt.”
Musk said, “If the 4th launch had failed, SpaceX would not exist.”

In late 2008, the firm was nearly out of cash. Another failure would have ended payroll, closed the Hawthorne factory, and left the Falcon 9 and Dragon programs as unfinished drawings.
The first flight lifted off from Omelek Island on 24 March 2006. Thirty-three seconds later, a corroded aluminum fitting on a fuel line leaked. Kerosene ignited around the Merlin engine, control was lost, and the vehicle came apart. The small DARPA payload, FalconSAT-2, survived the short flight only to land on a storage shed near the pad. Investigators later traced the fitting to a materials mix-up that should never have reached the rocket.
Flight 2, on 21 March 2007, looked far better at first. The first stage burned cleanly and handed off to the Kestrel-powered upper stage. The vehicle crossed 100 kilometers and reached a peak of about 289 kilometers. Then propellant slosh in the second-stage tank started a circular coning motion that grew until the engine shut down. Telemetry faded as the stage tumbled, and SpaceX had reached space but not orbit. Over the next year, the team redesigned everything from the ground up, including tanks, baffles, and the new regeneratively cooled Merlin 1C.
That engine flew on Flight 3 on 2 August 2008. The first stage performed almost perfectly and reached 217 kilometers. After main-engine cutoff, leftover fuel in the cooling channels produced a faint residual thrust, roughly 10 pounds per square inch of chamber pressure. On a Texas test stand, the effect was invisible beneath ambient air pressure. In vacuum it was enough to push the spent first stage back into the second stage after separation. The stages collided, the upper stage spun, and the mission was lost. Musk later said a slightly longer delay before staging would have saved the flight.
Six weeks later, the team assembled Flight 4 from remaining parts and flew it on 28 September 2008 at 23:15 UTC. The payload was Ratsat, a 165-kilogram aluminum mass simulator built in-house. Staging was delayed so residual thrust could decay. The Kestrel ignited, the fairing split away, and nine and a half minutes after liftoff the vehicle was in orbit. After a coast, the second stage restarted, settling into a 621-by-643-kilometer path at 9.35 degrees inclination. Falcon 1 became the first privately developed liquid-fueled rocket to reach Earth orbit. Musk called the insertion “middle of the bull’s-eye.”
SpaceX restores a Falcon 1 rocket for 10th anniversary of first launch success
That success unlocked NASA’s Commercial Resupply Services award later that year. Without it, there would have been no Falcon 9, no reusable first stages, and no Dragon cargo or crew flights to the International Space Station. Launch prices would have remained far higher. Starlink’s constellation would not exist; broadband from low Earth orbit would still be a paper concept.
Ride-share markets, high launch cadence, and the current pace of lunar and Mars hardware would be years behind. Communications, Earth observation, and the cost of putting anything into space would look more like the 2000s than the 2020s.
One extra second of residual thrust in August 2008 would have written a different decade.
