SpaceX Starship rolls to Texas launch pad ahead of next big test campaign
SpaceX’s first flightworthy Starship prototype has rolled to its South Texas launch pad just hours after it was welded together and is now preparing for several critical tests it must pass before it can be deemed ready for liftoff.
Fabricated and assembled with incredible speed at SpaceX’s growing Boca Chica, Texas Starship factory and test facilities, the vehicle SpaceX moved to the launch pad earlier today (Feb 25) is meant to become the first full-scale Starship prototype to take flight. Following in the footsteps of the Starship Mk1 prototype, deemed too shoddy to launch and pressurized to destruction in November 2019, the first serial build (SN01) of an improved line of Starship prototypes appears to have taken less than a month to go from first weld to the launch pad.
CEO Elon Musk took to Twitter earlier today to confirm the Starship SN01 tank section’s move to the launch pad, further noting that the tank assembly is now preparing for Raptor engine installation ahead of a static fire test. According to NASASpaceflight.com, SpaceX wants to complete that static fire and launch Starship SN01 as early as next month – a seemingly improbable target that just got much more likely with the rocket’s tank section already at the launch pad. Most importantly, however, the speed with which SpaceX has been able to assemble and prepare Starship SN01 suggests that even if things go wrong or plans change, another completed prototype could be ready to head to the pad just a few weeks from now.
On February 25th, SpaceX CEO Elon Musk posted a screenshot taken from a livestream created by SPadre earlier that day, noting that Starship will soon have engines installed in preparation for a critical static fire test.
Under the cover of an incredibly thick fog bank, Starship SN01 was lifted onto a Roll Lift transporter and carefully moved from its factory facilities to SpaceX’s Boca Chica launch pad at 4:30 am PST. Around 7:30 am PST, the giant rocket tank was lifted onto the pad’s Starship mount and technicians have been working to connect SN01 to the ground systems ever since.
Built out of stainless steel, Starship SN01’s tank section – referring to the combined liquid oxygen tank, liquid methane tank, and engine section – stands about 30m (100 ft) tall and likely weighs at least 30-45 metric tons (~70,000-100,000 lb) as it stands. While SN01 is clearly missing its pointed nose section (‘nosecone’) and flaps, among other parts, its tank section has been moved to the launch pad to perform tests that don’t involve the ship’s aerodynamic properties.
Starship Mk1 – SpaceX’s first attempt at a full-scale prototype – was fabricated and stacked piece by piece over the course of nine months before its tank section – looking almost identical to SN01 – first rolled to SpaceX’s launch pad on October 30th, 2019. Three weeks later, it was intentionally pressurized until it popped after engineers concluded that its production quality was too low for a flight test attempt to be worth the effort. On the other hand, the first of Starship SN01’s steel rings was definitively completed in the last week of January 2020, quite possibly just four weeks before the completed tank section was rolled to the same launch pad.
With that kind of speed, it’s no surprise that Musk says SpaceX will start stacking Starship SN02’s tank section this week. Intriguingly, Musk also stated that Starship SN02 would have three Raptors installed, avoiding the original question’s focus (SN01). As such, it appears that Starship SN01 may only have one Raptor installed for a static fire test and would be unlikely to ever fly if that were the case. It’s possible that after two highly successful (and explosive) pressure tests of smaller Starship test tanks that were completed last month, SpaceX still wants to perform a similar pressure test with a fully-integrated, full-scale Starship tank section to confirm that the smaller tank results carry over.
Whether SN01 is still destined for flight, it’s safe to say that Starship SN01 tank testing could begin in a matter of days — SpaceX currently has early-morning roadblocks indicative of such testing scheduled from February 29th to March 2nd. SpaceX is likely to kick off by filling SN01 with water to check its tanks for leaks, followed by liquid nitrogen – chemically neutral but still incredibly cold. After that, SN01 would likely graduate to Raptor engine installation and a wet dress rehearsal (WDR) with liquid oxygen and methane before moving on to a static fire attempt, if all goes well.

Tesla has reached a notable benchmark in its autonomous driving program after its Robotaxi fleet surpassed one million miles of unsupervised operation. The company made the announcement during its Cybercab event in Austin on September 3.
Tesla Vice President of AI Ashok Elluswamy told attendees he was happy to report the fleet had achieved one million miles of unsupervised Robotaxi operation as a testament to safety.
The new total marked a sharp increase from the 380,000 unsupervised miles Tesla disclosed during its second-quarter 2026 earnings update in late July.
In roughly six weeks, the company added about 620,000 miles. That acceleration followed Tesla’s decision to remove in-vehicle safety monitors from most of its operations outside the San Francisco Bay Area.

Tesla first launched Robotaxi service in Austin in June 2025 with safety drivers present. It later began fully unsupervised rides and expanded into Dallas, Houston, Miami, Orlando, and Tampa. The San Francisco Bay Area remains the exception, where a safety monitor still rides in the vehicle under California permitting rules.
The company has not released a city-by-city breakdown of the one million unsupervised miles.
The milestone arrived as Tesla began offering public Cybercab rides in Austin. The purpose-built vehicle has no steering wheel or pedals and is designed only for autonomous ride-hailing. Production versions joined the existing fleet of modified Tesla vehicles already operating in the service.
Tesla’s unsupervised mileage is growing at a double-digit weekly rate according to earlier company comments, yet its fleet size remains modest compared with established competitors. Waymo has accumulated more than 200 million fully autonomous rider-only miles. Tesla has described its own unsupervised operations as having recorded zero notable incidents in the period leading up to the July update.
The one-million-mile figure reflects Tesla’s shift from supervised testing to broader driverless service in multiple states. It also highlights the company’s strategy of using both existing Model Y vehicles and the new Cybercab to scale its network.

Whether the rapid recent growth continues will depend on further city expansions, regulatory approvals, and the performance of the purpose-built Cybercab in everyday paid rides. Tesla has not specified how many of the latest miles involved the new vehicle versus the rest of the fleet.
The announcement underscores Tesla’s progress toward a larger robotaxi network while illustrating the remaining gap in total autonomous experience relative to longer-operating rivals.
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.
It may also engage if we…

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.
