SpaceX shuffles Starships, gears up for more Super Heavy static fires
SpaceX is busy preparing for the orbital launch debut its next-generation Starship rocket, but the company’s South Texas rocket factory is also working around the clock to prepare several more sets of ships and boosters for the flight testing that will follow.
That was more obvious than usual on November 8th, when SpaceX made moves to prepare both of its finished Starships for new phases of testing. SpaceX kicked off the busy day by removing Starship S25 – a newer prototype that arrived at the launch site just three weeks prior – a stand dedicated to proof testing ships. Three hours later, after spending three of the last four weeks sitting on top of Super Heavy Booster 7, Starship S24 was ‘destacked’ (lifted off of B7 and lowered onto a stand on the ground) in the early afternoon.
Booster 7, Ship 24, and Ship 25 have all been busy since mid-October. SpaceX stacked Booster 7 and Ship 24 for the first time on October 11th and then attempted to test the fully-stacked rocket on October 13th. By some accounts, although almost nothing was visible to the public, the first full-stack test may have gone poorly, potentially even endangering pad technicians that approached the rocket to troubleshoot. On October 16th, SpaceX fully destacked Ship 24, and CEO Elon Musk noted that the company was “proceeding very carefully” to avoid an explosion that could set “Starship progress back by ~6 months.”
But if there was a major issue on October 13th, SpaceX didn’t show it, and Ship 24 was reinstalled atop Booster 7 on October 20th without any obvious maintenance or repairs. SpaceX then kicked off an unusual series of tests on October 24th, during which it only filled the liquid oxygen (LOx) or liquid methane (LCH4) tanks of Super Heavy B7, Ship 24, or both vehicles at once. A rare NASA briefing on October 31st later called them “single-species prop[ellant]” tests – a kind of extra-cautious testing that had never been seen before at Starbase. A few days prior, a member of NASA’s Aerospace Safety Advisory Panel (ASAP) noted that an accidental explosion that damaged Booster 7 in July had caused SpaceX to “increase [the rigor of its] systems engineering and risk management,” explaining the sudden influx of unusually conservative testing.
By the time Ship 24 was destacked from Booster 7 on November 8th, SpaceX had completed seven single-species tests, four of which involved loading LOx or LCH4 into both stages and three of which only tested Super Heavy. Booster 7 and Ship 24’s tanks were fully filled and LCH4 and LOx were never simultaneously loaded on either stage.
NASA’s October 31st briefing reported that SpaceX had plans to destack Ship 24 before conducting additional static fire testing with Booster 7. While B7 completed 1, 3, and 7-engine static fires in August and September, those tests were nowhere close to the full 33-engine static fire required to properly qualify the most powerful rocket in history. According to NASASpaceflight.com managing editor Chris Bergin, SpaceX’s next goal is to fire up approximately half of Super Heavy B7’s Raptors.
Strangely, although Ship 24 was believed to have completed all of the standalone testing needed to clear it for flight, SpaceX installed the vehicle on a stand used for Starship static fire testing on November 9th, implying that more standalone testing may be required. For now, that shouldn’t pose a problem as long as SpaceX wraps up any additional Starship testing around the same time as Booster 7’s next static fire campaign wraps up, but it could delay full-stack launch readiness if it takes any longer.
Finally, after Ship 25 was removed from SpaceX’s other Starship test stand on November 8th, it was rolled back to Starbase’s Starship factory. Ship 25 first rolled to the launch site on October 19th and has since completed four visible tests. On October 28th, Ship 25 survived a pneumatic proof test that showed that its tanks were leak-free and capable of surviving flight pressures (roughly 6-8.5 bar or 90-125 psi). Three cryogenic proof tests followed on November 1st, 2nd, and 7th. The first cryoproof was likely just that – a test that pressurized Ship 25’s tanks and filled them with cryogenic liquid nitrogen (LN2) or a combination of liquid oxygen and LN2.
The next two tests likely took advantage of the customized test stand, which has been semi-permanently outfitted with a set of hydraulic rams that allow SpaceX to simulate the thrust of six Raptor engines while Starship’s structures are chilled to cryogenic temperatures and loaded with roughly 1000 tons (~2.2M lb) of cryogenic fluids. If a Starship can survive those stresses on the ground, the assumption is that it will likely survive similar stresses in flight.
Assuming that Ship 25’s first several proof tests were successful, which they appear to have been, SpaceX returned the prototype to its Starbase factory to install six Raptor engines and a series of shields and firewalls that will protect those engines from each other. Once fully outfitted, Ship 25 will return to the launch site for static fire testing and take Ship 24’s place on Suborbital Pad B. Ship 24 took approximately two months to go from its last cryoproof to its first static fire. But its testing got off to a relatively rocky start, so Ship 25 could be ready sooner.
SpaceX could begin the next phases of Booster 7 and Ship 24 testing as early as November 10th or November 13th.
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.
🚨 A Tesla Semi reportedly caught fire, with California Highway Patrol confirming. The Semi was on I-880 SB

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.
