SpaceX Starship factory breaks ground on an even bigger ‘high bay’
SpaceX appears to have more or less broken ground on a new, even bigger ‘high bay’ assembly facility at its Boca Chica, Texas Starship factory.
Barely one year ago, SpaceX erected the first prefabricated steel sections of what eventually become its Starship factory ‘high bay’ – a spartan 81m (~265 ft) tall designed at the most basic level to shield final Starship and Super Heavy booster assembly from the elements. Situated near the southernmost tip of Texas and just a few miles west of the Gulf of Mexico, those “elements” can be less than pleasant at SpaceX’s primary Starship factory, ranging from sauna-like heat and humidity and mosquitoes the size of quarters to regular downpours, thunderstorms, tropical conditions, and even hurricanes.
While a great deal of work at Starbase is still done out in the open with little more than an umbrella as protection, SpaceX has nevertheless worked to find a middle ground where the most sensitive work (mainly structural welding) can be mostly shielded from wind and rain. First, SpaceX built a (relatively) tiny ‘windbreak’ too small for much of anything. Two years later, the windbreak is partially used for Starship nose section assembly – when a nose cone is stacked on and welded to a separate stack of four steel rings.
A few months after the triangular windbreak was fully finished, SpaceX started work on a larger box-like building that would eventually be known as the Starship factory’s ‘midbay.’ Standing around 45m (~150 ft) tall, the midbay was designed to support the process of assembling Starship tank sections from several stacks of 2-4 steel rings but was – for whatever reason – left too short to support the full Starship assembly process.
Instead, once Starship tank sections were finished, they would have to be rolled out of the midbay for nose installation. Eventually, in July 2020, SpaceX began assembling an even larger ‘high bay’ that would ultimately measure 81m (~265 ft) tall and 20-25m (65-80 ft) wide and deep – easily big enough to fit the company’s existing Falcon 9 or Falcon Heavy rockets with room to spare. More importantly, of course, the high bay was built to be large enough to support Super Heavy assembly from start to finish, giving SpaceX teams a sheltered place to build the largest rocket boosters in history.
As of August 2021, SpaceX’s midbay has supported the assembly of 10 Starship prototypes, 5-6 propellant storage tanks, and several ‘test tanks,’ while the newer high bay has helped SpaceX build three (mostly) complete Super Heavy boosters in 2021. However, working at full speed, SpaceX’s midbay is really only capable of supporting the assembly of one Starship tank section (and more general work on two) at a time and the high bay – while offering at least twice the covered surface area – appears to be limited to simultaneous work on two or three different stacks (boosters, ships, tanks, etc.).
As SpaceX slowly but surely treks towards the end of approximately two years almost exclusively dedicated to building ever-changing prototypes, it’s been clear for a while that the company would need to drastically expand its production facilities to produce the dozens of Starships and boosters CEO Elon Musk has been publicly dreaming of. Even at lower volumes, those existing facilities – while great for producing a dozen or more prototypes per year – would still become a chokepoint for the near-term production of a small fleet of operational Starships and Super Heavies.

In turn, Musk revealed that SpaceX was about to start building “a much larger high bay” adjacent to the existing structure in late July. On August 20th, a little over a year after assembly of the original high bay kicked off, SpaceX began the process of tearing up existing concrete for the even larger bay – breaking ground, at least in a sense. According to Musk, the newest addition to Starbase’s Starship factory will be about 10% taller (~90m vs 81m), substantially wider, and likely a bit deeper than the existing high bay, allowing for the installation of two side-by-side bridge cranes with tracks running the full width of the building.
With at least 2-3 times more surface area than the high bay, the new wide bay should give SpaceX enough space to simultaneously assemble something like 4-8 Starships or Super Heavy boosters. Depending on which direction SpaceX goes, the wide bay could also potentially be large enough for SpaceX to create the first true Starship and Super Heavy assembly lines, though that would be a substantial departure from Starbase’s existing approach to manufacturing.
Tesla AI lead Ashok Elluswamy said this week that 24-hour Robotaxi service is close. Replying on X to a rider who wanted Cybercab trips all night, he wrote that the capability would arrive “next month or so” once “the next tech to merge on the v15 plan” is ready.
The comment landed on September 4, one day after Tesla opened public Cybercab rides in Austin. It is the clearest near-term timeline yet for overnight unsupervised operation. Tesla’s paid Robotaxi network currently runs from 6 a.m. to 10 p.m. seven days a week across Austin, Dallas, Houston, Miami, Orlando, and Tampa.
next month or so. the next tech to merge on the v15 plan will enable it.

That 16-hour window is shorter than the 6 a.m. to 2 a.m. schedule the company used for much of the prior year.
Elluswamy did not name the specific feature or say whether the change would apply first to purpose-built Cybercabs, the existing Model Y fleet, or both. He also offered no city-by-city rollout list. The link to Full Self-Driving v15 is nevertheless significant.
Tesla has described v15 as a step-change architecture with seven parallel improvement tracks and roughly ten times more parameters than earlier builds. Early versions of that software already operate on the Robotaxi fleet and contain about 40 percent of the planned gains.
By July 2026, the unsupervised fleet had logged more than 380,000 miles across six cities in two states with what the company called an impeccable safety record and no notable incidents caused by the vehicles themselves. Tesla has repeatedly argued that camera-based end-to-end neural networks, rather than extra sensors, are the core of the solution.
Overnight service would test that claim in lower-light conditions and would also raise vehicle utilization, a key variable for Robotaxi unit economics. The company has already begun using public Superchargers at night and is building dedicated Robotaxi charging sites.
Riders have asked why software must change if the cars already drive in the dark. The practical answer appears to be reliability and scale: Tesla has held back mass expansion until more of the v15 stack is merged, citing the need for higher confidence before putting thousands of unoccupied vehicles on streets around the clock.
If the next module arrives on the timetable Elluswamy sketched, 24-hour service could begin in October 2026 in at least some markets.
That would mark a shift from a daytime-bounded pilot to a service that can run whenever demand exists, including the late-night hours that have so far remained out of reach.
Tesla is beginning to roll out Full Self-Driving Supervised v14.3.9 with a new active safety layer that can take control even when the driver is operating the car manually.
Tesla AI said the software can activate FSD on the driver’s behalf when an imminent collision is detected and Automatic Emergency Braking may not be enough. It may also engage if the system detects heavy distraction or an accidental FSD disengagement.
FSD Supervised v14.3.9 starting to roll out shortly
This release includes a new active safety feature set: FSD Supervised can now activate on your behalf when an imminent collision is detected and Automatic Emergency Braking (AEB) may not be enough.

The capability is essentially Automatic Collision Evasion. However, unlike conventional AEB, which mainly applies the brakes in a straight line, this feature can use steering, braking, and acceleration together if the car calculates that stopping alone will not prevent impact and a safer path exists. The system may change lanes or move toward a shoulder when conditions allow, then continue driving after the immediate threat is handled rather than simply coming to a stop.
The intervention is meant as a last-resort safety net, not a replacement for attentive driving.
Tesla Full Self-Driving v14.3.7 early review: FSD saved me from an accident
Tesla’s own description still frames FSD as supervised assistance. Secondary reports on internal release notes say the feature can fire while the car is being driven manually if cabin-camera monitoring suggests the driver is not sufficiently attentive, such as reaching toward the back seat, or if FSD appears to have been turned off unintentionally.
After the emergency maneuver, the car is expected to alert the driver and request a return to manual control.
The safety case is straightforward. Many collisions happen in the last second because a driver is looking away, fumbles a control, or faces an obstacle that braking cannot fully solve. A system that can both recognize that AEB is insufficient and execute a coordinated evasive path can reduce those remaining high-severity events.
Re-engaging after accidental disengagement also addresses a practical failure mode: a small steering nudge that drops FSD at the worst moment. The advantage is a background safety net that uses the same vision stack already running in v14, instead of leaving the car solely to emergency braking once the driver is no longer in command.
The feature still depends on FSD being enabled and, according to reports, an active FSD purchase or subscription. It does not make the vehicle unsupervised. Drivers remain responsible, and Tesla has not published how often the system is expected to intervene or how it will handle false positives.
If the rollout is conservative and the false-alarm rate stays low, the update is a meaningful step: FSD is no longer only a feature the driver turns on. In the rare moments when disaster is already forming, it can step in.
Tesla launched the all-electric, steering wheel-less, and pedal-less Cybercab last night at a quiet and small event in downtown Austin, Texas.
The launch, which marked the beginning of unsupervised ride-hailing for Tesla’s Robotaxi platform with Cybercab, has already caught the attention of the National Highway Traffic Safety Administration (NHTSA) who has more questions.
NHTSA opened an Audit Query (AQ) into the Cybercab’s Federal Motor Vehicle Safety Standards (FMVSS) certification that Tesla gave the vehicle. Manufacturers self-certify vehicles much of the time to avoid excessive regulatory delays.

However, the agency needs more information; it said in a summary:
“On September 3, 2026, Tesla began commercial deployment with a small number of its Cybercab vehicles in Austin, Texas. Tesla notified the Agency that it certified those Cybercab vehicles as compliant with all applicable Federal Motor Vehicle Safety Standards (FMVSS). Tesla also notified the Agency that it plans to gradually expand commercial deployment of the Cybercab to include additional vehicles and locations.”
It also went on to state that the Cybercab lacks traditional automotive controls, which is a groundbreaking move. The process is entirely new to the NHTSA, which gives the agency some leverage to put Tesla’s launch under a microscope:
“The vehicles lack permanently attached, conventional manual controls, such as a brake pedal, gas pedal, steering wheel, and mirrors. NHTSA is opening this AQ to examine the process and technical data on which Tesla relied when certifying the Cybercab and related issues. Among other things, NHTSA will consider the extent to which Tesla’s certification depended on determinations that certain FMVSS are inapplicable to the Cybercab.”
Tesla has added 45 Cybercab units to its fleet of Robotaxi-enabled cars in Austin, according to public documents the company submitted to the State of Texas over the past week. Enabling this level of self-driving is something Tesla has worked toward for many years, and now that it is finally here, it seems more than reasonable that regulatory agencies will have some questions.
Many outlets might try to frame this as a negative, but it is truly an agency looking to gain more information about groundbreaking tech that Tesla has been developing for years.
In an effort to keep riders, pedestrians, and property safe, any and all data accumulated from these first days, weeks, and months of rides will likely be shared with the NHTSA to enable broader rollout strategies across the United States and more in the future.
