SpaceX ‘go’ for 50,000-foot Starship launch debut after static fire, Elon Musk says
CEO Elon Musk says that SpaceX’s first fully-assembled Starship prototype is on track for its 15-kilometer (~50,000 ft) launch debut after completing a second three-engine static fire test on Tuesday.
Starship serial number 8’s (SN8) three Raptor engines ignited for a few seconds around 5:30 pm CST (UTC-6) on Tuesday, November 24th, less than four hours before a record-breaking Falcon 9 rocket launched another batch of Starlink satellites roughly a thousand miles to the east. Perhaps briefly producing upwards of 600 metric tons (6000 kN/~1.3M lbf) of thrust, Starship SN8’s second triple-engine static fire was actually the first with that particular trio of engines.
Back on November 13th, an otherwise successful one or two-engine static fire nearly ended in catastrophe when the hypersonic Raptor exhaust kicked up blade-like debris that severed crucial control cables and triggered an apparent engine meltdown. Thanks to a “burst disk” failsafe, Starship SN8 – unable to actuate valves needed to depressurize – was saved from what could have been catastrophic damage. Believed to be SN32, the damaged Raptor was subsequently removed on November 14th and replaced with SN42 on November 16th.
As such, SN8’s November 24th static fire was the first with that particular set of three engines, although it was technically the rocket’s second three-engine test. SN42 now (hopefully) proven to be flight-ready, it remains to be seen if SpaceX will attempt more static fires before Musk’s promised 15 km launch debut.
As of November 25th, SpaceX still has a static fire backup window open open from 8 am to 5 pm CST, while Starship SN8’s launch road closures remain in effect from 7 am to 6 pm on November 30th with backups from 8 am to 5 pm on December 1st and 2nd.
Having now spent more than a month at the launch pad, it’s increasingly unlikely that SpaceX will continue to choose caution first for upcoming Starship SN8 tests. As Musk recently noted and easily visible from public roads, SpaceX’s Boca Chica factory is developing an extraordinary backlog of giant steel rockets. Just today, November 25th, Starship SN9 (featuring “small improvements”) was stacked to its full 50-meter (~165 ft) height after SpaceX kicked off nose section installation. In simpler terms, if SN8 is destroyed during testing, Starship SN9 will likely be ready to roll to the launch site almost as soon as the pad is clear.
Meanwhile, Starship SN10 is likely just 7-10 days away from a similar nosecone stacking milestone and Starship SN11’s tank section is just one stack away from completion, likely putting it less than two weeks behind SN10. In other words, insofar as speed is a priority and each prototype is anywhere close to as cheap as Starship’s majority-steel bill of materials might suggest, SpaceX is building the rockets so quickly that it almost doesn’t make sense to spend more than a few weeks working through any given ship’s bugs for as long as prototypes remain firmly suborbital.
Musk also says that Starship SN15 will be the host of some mysterious “major upgrades”, likely implying some substantial manufacturing improvements and design refinements. Given that large portions of Starship SN15 (and likely SN16, too) are already visibly in work in Boca Chica, it makes even less sense to spend outsized amounts of time on a much earlier prototype.
It doesn’t come as a huge surprise, then, that Musk has given SN8 – warts and all – a 33% chance of successfully launching, ‘skydiving’ back to Earth, reigniting one or more Raptors, and landing in one piece. The only real certainty is that regardless of the outcome, Starship’s high-altitude launch debut is guaranteed to be spectacular. Stay tuned for updates as we get closer to SpaceX’s November 30th target.
A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
