SpaceX’s Elon Musk hints at “notable” Starship changes, explains static fire anomaly
CEO Elon Musk has offered an explanation for SpaceX’s recent Starship static fire anomaly and says that an overview of the next-generation rocket development program will be delayed to account for some “notable” design changes.
Over the last several months, Musk has promised to do one of his (thus far) usual annual Starship updates, either in the form of a presentation in South Texas, an article published on SpaceX’s website, or both. Originally expected in September or October, the CEO’s tentative schedules have come and gone several times. Simultaneously, however, SpaceX has been preparing Starship serial number 8 (SN8) for a range of crucial tests and Starship program firsts, recently culminating in a successful cryogenic proof test, multiple wet dress rehearsals (WDRs), nosecone installation, the first triple-Raptor static fire test, engine tests using smaller ‘header’ tanks, and more.
Unfortunately for SN8, the most recent Raptor engine header static fire – drawing propellant from two small internal tanks mainly used for landing burns – did not go according to plan, resulting in some kind of high-temperature fire and severing Starship’s hydraulic systems. For SpaceX test controllers, that meant a total loss of control of most vehicle valves and pressurization systems, essentially putting one of Starship SN8’s header tanks through an unplanned pressure and failsafe test. In the days since, what exactly caused that unfortunate failure has been the subject of a great deal of discussion – discussion that can finally be put to rest with new information from Musk himself.
In a surprise, SpaceX had apparently decided to add a failsafe to Starship SN8’s new nose section, installing what is known as a burst disk – effectively an automatic single-use valve. Once the upper (liquid oxygen) header tank reached dangerous pressures, the force of that pressure broke the seal, allowing the rocket to vent excess pressure and avoid what would have otherwise been a potentially catastrophic explosion.
The cause of that near-miss, according to Elon Musk, was as simple as debris kicked up during the Starship SN8 Raptor engine static fire directly prior. Producing up to 200 metric tons (~450,000 lbf) of thrust and an exhaust stream traveling some 3.3 kilometers per second (2 mi/s, Mach ~10), Musk says that Raptor tore apart a special ceramic coating covering the concrete directly beneath Starship SN8. Likely accelerated to extreme velocities in milliseconds, shards of that coating reportedly “severed [an] avionics cable, causing [a] bad [Raptor engine shutdown].”
Prior to Musk’s comments, SpaceX technicians had already removed on of SN8’s three Raptors – SN32 – on November 14th and replaced it with Raptor SN42 on November 16th, effectively confirming that any damage suffered by Starship’s engine section was easily repairable. It’s unclear how exactly a single severed cable could result in a Raptor engine seemingly dripping molten metal but regardless of the cause, the fix appears to have been a quick one.
In response to the anomaly, Musk says that Starship avionics cables will ultimately be routed inside steel pipes to shield them from debris, while “water-cooled steel pipes” will be added to the launch pad to help limit the damage Raptors can cause. Perhaps as a partial result of SN8’s troubles at the launch pad, Musk says that his Starship blog post will have to wait, as SpaceX “[may be] making some notable changes” to the launch vehicle.
Prior to Starship SN8’s failed November 12th Raptor test, SpaceX was expected to attempt three consecutive static fires before clearing the rocket for an ambitious 15 km (9.5 mi) flight test. One of those static fires had already been completed on November 10th and it’s unclear if SpaceX’s SN8 test plan has remained unchanged or if the static fire counter has been effectively reset. Either way, barring more surprises, there’s still a definite possibility that Starship SN8 will be ready for its launch debut by the end of November and an even better chance that it will launch some time between now and 2021. Stay tuned for updates!
SpaceX plans to attempt what will be a defining moment in rocket reusability on Starship Flight 15.
As Elon Musk announced in a recent X post, SpaceX will attempt to catch both the Super Heavy Booster and the Starship upper stage during the upcoming orbital flight. If successful, it will mark the first time that all parts of an orbital rocket return to Earth intact, a breakthrough Musk has called essential to making life multiplanetary.

Previous flights have demonstrated the tower-catch technique with Super Heavy. SpaceX has successfully caught V1 boosters three times (on Flights 5, 7, and 8), with some even reflown. The Ship upper stage has never been caught.
Returning from orbital velocity after deploying payload makes it a significantly harder challenge due to higher energy, heat loads, and the need for precise belly-flop reentry, a flip maneuver, and a final landing burn to settle between the Mechazilla tower’s chopstick arms.
Flight 15, using Booster 22 and Ship 42 (both Block 3 vehicles), is targeted for no earlier than Friday, November 13, 2026, from Orbital Launch Pad 2 at Starbase, Texas. The 75-minute window opens at 4:45 p.m. CT, pending regulatory approval. After hot staging and separation, the booster is planned to return for a catch roughly 6 minutes and 35 seconds after liftoff.
The Ship will insert into a roughly 275 km orbit, deploy 26 advanced Starlink V3 satellites, complete about 14 orbits over more than 22 hours, and—if systems check out—perform a deorbit burn, reentry, flip, and landing burn for a tower catch at approximately T+22 hours 32 minutes.
SpaceX confirms Starship 15 launch window with massive ambitions
A simulation shown during SpaceX’s October earnings call depicted the Ship descending in a belly-flop attitude, flipping upright with a short engine burn, and being captured by the arms:

SpaceX is just ONE WEEK away from attempting its most ambitious Starship catch yet https://t.co/nHrxSX6DSz

Contingency splashdown zones exist in the Gulf of Mexico (booster) and Pacific (Ship) if a catch is not viable. SpaceX has stressed rigorous health checks before committing the Ship to a return-to-launch-site trajectory.
Musk has described the odds of success on this first dual-catch attempt as “more likely than not,” noting a steady stream of additional flights is already scheduled if needed. Full recovery would enable rapid inspection, refurbishment, and reflight—slashing costs and supporting the high launch cadence required for Starlink expansion, lunar missions, and eventual Mars settlement.
As Musk put it, this is “the critical breakthrough needed to make life multiplanetary.”
Tesla Cybercab is going to get some pretty substantial updates, including improvements to efficiency and a new color.
CEO Elon Musk said in a post on X on Saturday that Tesla would be working to refine the Cybercab even more, following the announcement during the week that the company would eliminate the Cybertruck lines within Giga Texas for more Cybercab manufacturing capacity.
“There are efficiency improvements coming that will allow for a 40kWh Cybercab pack,” Musk posted on X. “We will make this in liquid silver, so the colors are not too monotonous.”
There are efficiency improvements coming that will allow for a 40kWh Cybercab pack. We will make this in liquid silver, so the colors are not too monotonous.
The biggest thing most people fail to understand is that there are a very limited number of smart, dedicated people! They can only do so many things.
If we have to maintain a complex production line, supply chain and allocate engineering for Cybertruck, we can’t use those people or factory space and machinery for scaling Cybercab, which is the vehicle that will PROFOUNDLY transform the world of terrestrial transport!
— Elon Musk (@elonmusk) November 7, 2026
A new, more efficient model of the Cybercab will be engineered, which will only help Tesla’s profitability and margins, and it also boosts the argument for why the Cybertruck should be discontinued, at least from a business perspective.
The current Cybercab that operates in the Robotaxi platform in Austin, Texas, has a 48 kWh pack, and it sounds like Musk believes Tesla is on its way to introducing a version that has fewer cells but can manage the same workload thanks to engineering efficiencies.

Musk also doubled down on the decision to prioritize Cybercab production over Cybertruck, which is a decision that has been extremely polarizing within the community, and many fans have made it abundantly clear that they are not particularly pleased with the plans.
“If we have to maintain a complex production line, supply chain, and allocate engineering for Cybertruck, we can’t use those people or factory space and machinery for scaling Cybercab, which is the vehicle that will PROFOUNDLY transform the world of terrestrial transport,” Musk said.

Cybercab is obviously Tesla’s path forward in an automotive sense. It seems that Tesla is less concerned about catering to the passenger vehicle market and is more prone to focus on transforming passenger transportation in a way that prioritizes autonomy. However, this requires some sacrifice on Tesla’s end, and the Cybertruck is unfortunately a victim of this.
Cybercab holds an extremely crucial part of Tesla’s future. With the company already revolutionizing passenger transportation once, this is the next phase, and Cybercab is the path forward.

Tesla Robotaxi app update now tells riders if Cybercab is the better choice
Tesla’s Robotaxi app now shows ETAs, wait times and availability for Cybercab and Model Y.
Tesla has rolled out a new vehicle selection screen in its Robotaxi app, and it puts the numbers riders care about most in front of them before they book.
Version 26.11.0 of the app shows the estimated arrival time, the expected wait and current availability for each vehicle option on a single screen, according to a video shared by @gheeunit on X on November 7. Riders deciding between a Cybercab and a Model Y Robotaxi can now compare those figures side by side instead of picking a car first and learning how long it will take afterward.
Tesla first gave riders that choice on September 3, the day paid Cybercab rides began in Austin. The original version of the screen listed the Cybercab, which seats two, next to the Model Y, which seats four. A later build, 26.8.2, added a seating capacity indicator so groups knew which car would fit them. What it did not show was whether choosing the Cybercab meant standing on the curb a few extra minutes.
Newest version of @robotaxi app has a new vehicle selector UI for choosing between Cybercab and Model Y and shows you the fare for both simultaneously! https://t.co/7qoDQ0vACX — mantequilla 🧈 (@gheeunit) November 7, 2026
That question matters more now than it did two months ago. Tesla had 45 Cybercabs on the Texas DMV roster when rides started. By late October the state listed 573, alongside 631 Model Ys, and community trackers logged a record 1,576 Cybercab sightings across Austin on Halloween alone. With two large fleets sharing one service area, the closest car and the quickest pickup are not always the same vehicle.
Inline availability also changes what happens when demand spikes. If no Cybercab is free nearby, the rider sees that on the selection screen rather than after trying to book one.
For now the comparison is mostly an Austin feature. Riders in Dallas, Houston, Fort Worth and the Florida markets are still matched with Model Y vehicles, though Tesla said on its third quarter earnings call that Cybercab rides would launch in Dallas this month.
The update follows a steady run of smaller changes to the rider experience. Late last month Tesla brought a quiet mode that blacks out the cabin screen to Model Y Robotaxis after first testing it in the Cybercab, and it has stretched Austin service to run from 6 a.m. to 2 a.m.
The Cybercab side of that selection screen is about to get much busier. Elon Musk said this week that Tesla will wind down Cybertruck production at Gigafactory Texas around the middle of 2027 to make room for more Cybercab output, and Tesla has said it is aiming to get Cybercabs to customers by the end of this year.
Tesla has not published official release notes for version 26.11.0.
